The Molekule Air Mini+ is a small but innovatively designed air purifier. It boasts medical-grade materials and patented PECO filter technology, using UV radiation to help further destroy airborne pollutants.

I tested it to see whether it could compete with our pick of the best air purifiers on the market. It's simple to use and has an aesthetically pleasing app, but the only data that gets recorded is the air quality, in a range running from Good to Very Bad. This means that, unlike some cheaper air purifiers, there's no breakdown of the type of particles contaminating the air. In addition, the Molekule Air Mini+ can't detect VOCs (volatile organic compounds), making it hard for this purifier to tackle odors without manual intervention.

Note: the Pro version of this purifier does detect VOCs and is particularly good at tackling odors, but that model is significantly bulkier and more expensive (read my Molekule Air Pro review for more on that one). Alternatively, read on for my full Molekule Air Mini review below.

Molekule Air Mini+ review: price & availability

• List price: $359.99
• Only available in the US at present

At $359.99, the Molekule Air Mini+ isn’t cheap. You’d be forgiven for thinking that this must mean it’s packed with features, but Molekule has kept things seemingly simple with this model. Perhaps too simple, in my opinion, as cheaper alternatives can give more detailed readings.

What this purifier does have in comparison to these lower-priced alternatives, however, is patented PECO technology. This allegedly breaks down organic matter at a molecular level. While I can neither confirm nor deny that this is accurate, this, along with the use of medical-grade polycarbonate, would go some way to explain why the price point is as high as it is.

But I found myself asking: is this quality filter being used to its full potential if the Air Mini+ can't detect VOCs in order to respond appropriately in the first place?

The Air Mini+ is available to purchase directly from the Molekule website and on Amazon, but only in the US at present.

Molekule Air Mini+ review: design

• Simple aesthetic
• Redundant handle
• One-button control

Air purifiers can vary aesthetically: some look utilitarian while others make a statement, and the Molekule Air Mini+ sits somewhere in the middle. It has some fancy little design elements but, overall, I’ve gotta say, it’s kinda giving bathroom trash can vibes. That being said, it is at least a fairly compact size, standing at 12 inches tall, with a diameter of just over 8 inches. It’s surprisingly heavy for its size, weighing 7.3 lb, which is 4.8 ounces heavier than the much larger Shark NeverChange air purifier.

The white medical grade polycarbonate outer has a textured matte finish, with the word Molekule inlaid in shiny silver. On the right-hand side, a somewhat redundant tan-colored vegan leather handle is fixed in place by a large silver metal pin. It wasn’t easy or practical to carry it around using this, so it appears to be more of a design choice to keep it in line with the design concept of its larger sibling, the Molekule Air Pro.

There’s an inset gray band toward the bottom of the unit where the base meets the top section, and slanted gray slats at the top of the purifier circling the gray touch panel in the center. The control panel is subtle as no lights are on show until you touch the center to awaken the purifier. This center button is used to turn the power on and off, cycle through Auto Protect and manual fan modes, and reset the Air Mini+. In the middle of this button is the indicator light for the air quality in the room, it shows green for good, yellow for moderate, red for bad, and blue for very bad.

A series of white dots indicate the fan level, so one dot for the lowest fan speed, and five for the highest. It also shows an interlinked symbol when it’s in Auto Protect mode. There’s a Wi-Fi symbol that flashes up upon startup or if there are connectivity issues and a filter symbol that communicates the filter’s health.

In terms of packaging, the Air Mini+ comes in a shipping-style corrugated cardboard box, with consideration going into the cardboard fitments, eliminating the need for single-use materials like polystyrene. For extra protection, the purifier comes in a good-quality reusable drawstring bag.

Molekule Air Mini+ review: features

• Aesthetically pleasing app
• Lacking detailed air quality data
• Impressive (but expensive) filter

The Air Mini+ is compatible with the Molekule app, which has an attractive and easy-to-use interface with a cool-toned color palette and animations. Despite the app being simple to use, setting up the Wi-Fi connection was a bit of a headache, but I’ll regale my woes further in the performance section.

Once everything was connected, the Purifier tab on the app told me what the current IAQ was, from good to very bad. From this tab, I could also change between Auto Protect mode, or manually select a fan speed from one to five. There's also a percentage rating to show the PECO-Filter condition: when pressed, it provides further information on the filter capabilities and details on how to change it. In the More tab, you can connect to Alexa, add more air purifiers to the app, and enable or disable notifications.

The Indoor Air tab shows a timed graph spanning 24 hours or one week. Unlike this purifier’s larger (and much more expensive) sibling the Molekule Air Pro, there is very limited information provided by the Air Mini+. You simply see a graph that notes the IAQ using the same color-coded system as shown on the purifier itself, and the length of time the air quality was at that level. There's no details on whether the IAQ was affected by dust particles, pollen, smoke, volatile organic compounds (VOCs), and so on. Perhaps this is enough information for some users, but when air purifiers that cost at least $100 less can provide more detail, it’s quite disappointing that the readings are so basic from the Air Mini+.

The Molekule Air Mini+ has received FDA clearance and is classed as a device intended for medical purposes. It’s stated that it can capture 95% of particulate matter and destroy bacteria and viruses by exposing them to ultraviolet radiation – though only when in manual mode on fan speed three or above.

The Air Mini+ comes with a PECO-HEPA Tri-Power Filter, which Molekule states can destroy bacteria, mold and allergens, and reduce odors and toxic gasses, with a 99.97% particle-capture efficiency rate. Molekule recommends changing the filter every six months, which doesn’t sound excessive, but it’s important to note that a replacement filter costs $99.99, or $79.99 if you subscribe to bi-annual deliveries.

Molekule Air Mini+ review: performance

• Buggy Wi-Fi connectivity
• IAQ tracking not accurate
• Does not clear odors automatically

Having tried out many lower-cost purifiers and the Air Mini+’s highly talented sibling, I expected great things from this little purifier. The results from everyday use didn’t blow me away, unfortunately.

Upon initial setup at home, I couldn’t connect the Air Mini+ to my iPhone 12 Pro. I found that I needed to manually go into my Wi-Fi settings to find the Molekule Wi-Fi the purifier was trying to connect to. This action wasn’t prompted or made clear; on the app, a button just appeared asking to connect to the Molekule network, which would then throw up an error saying that it was unable to join. Once I’d discovered that I needed to join this network manually, my phone connected to the purifier.

Sadly, this wasn’t the end of the frustration. When it came to connecting the Air Mini+ to my Wi-Fi router, I was left with the spinning wheel of doom until I had to give up. I tried resetting the purifier, reinstalling the app, and restarting the Wi-Fi, but to no avail. I ended up admitting defeat late in the evening, which meant that even though the Air Mini+ was running overnight, it was not collecting any data. The only indication of the air quality was the colored indicator light on the top of the unit, which turns off until you touch it, so it wasn't easily visible from my bed. It’s unusual not to have Bluetooth backup available. I found this alternative connectivity option helpful when the lower-priced Welov P200 Pro wouldn’t connect to Wi-Fi, as at least it could still record data and be controllable as long as the device was in range.

I decided to test the syncing process with our OnePlus Pad Go, to see if this was an iOS, app, or firmware issue. Upon installing the Molekule app, it became clear that it wasn’t optimized for Android tablets, or certainly not in this instance anyway. The Auto Protect and Manual button on the Purifier tab went beyond the edges of the screen, and the chart in the Indoor Air tab didn't display properly, in either screen orientation. I couldn't use the OnePlus Pad Go to connect the Air Mini+ to the Molekule app again, as the page was too large for the screen, so it wasn't possible to go through the connection process.

When I tried to connect it to the Wi-Fi in the office the next morning, it was the same fun and games, until eventually, the app said that there was an issue connecting to the network and to try to reconnect. When I pressed the button to continue, it successfully connected to Wi-Fi and I was able to name my purifier on the app. I had the same issue when setting up the Molekule Air Pro, but it surrendered much quicker than the Air Mini+.

The biggest issue with the Wi-Fi not connecting was that, despite the price, the Air Mini+ doesn’t use Bluetooth, so if you can’t connect over Wi-Fi, the IAQ isn’t tracked and you can’t adjust settings hands-free.

One element that's been a cause of irritation for myself and my colleagues is that when switching between manual mode and Auto Protect, the fan speed builds up to its highest (and loudest) setting, even when the air quality is good. This isn’t great at the best of times, but if you’ve forgotten to set it onto auto when your baby is napping, or you’re in a quiet shared office, say, it’s very inconvenient. It was particularly off-putting when going to bed late at night, as it became more apparent to me that it took the fan some time to reduce to its final speed when I put it onto auto, even though it had only been on manual for a moment and the IAQ was good, meaning that the fan noise is loud for longer than it needs to be.

When using it in the TechRadar reviews office, the readings did not correspond with the Molekule Air Pro I had running simultaneously. The Air Pro detected a substantial drop in air quality on two occasions, which was when there was a lot of activity in the office. The reason that the two Molekule purifiers didn’t correspond with one another is simple – the Air Pro can detect an increase in VOC, but the Mini+ lacks this ability. While this can’t be held against the Mini+ due to the massive price difference between the two, before settling on a purifier you should consider the contaminants you want to be detected so that your purifier can react and clear the air fast.

I sprayed dry shampoo toward the Air Mini+ and it detected it quickly. The fan sped up gradually as a result, changing the IAQ from bad back to good within two minutes. The fan speed slowed gradually, even though the fragrance remained strong in the air. I manually set the purifier to full fan speed to clear the fragrance from the dry shampoo, it took the Air Mini+ about 30 minutes to clear the air. This is more than double the time it took the AiDot Welov P200 Pro, which left the air smelling fresher after just 10 minutes of running on full power.

One issue that became apparent is that the app does not always correspond with the reading on the purifier itself. When performing the dry shampoo test in the TR office it relayed the change in air quality after some time, but when I retested at home, it didn't register that the Air Mini+ was detecting bad air quality at all, relaying a fairly flatline reading of “good” over the whole day. While this isn’t the end of the world, as the purifier itself still reacted, it’s not ideal if you want to keep track of the air quality remotely or in the morning after a night's sleep, as the data does not feel reliable.

Molekule Air Mini+ review: Also consider

How I tested the Molekule Air Mini+

• I used the Molekule Air Mini+ for one week
• I tested it in multiple environments
• I observed its reaction to aerosols

I tested the Molekule Air Mini+ in the TechRadar reviews office and music testing room, as well as in my bedroom at home.

I monitored how effectively it detected and purified airborne contaminants such as dust and dry shampoo, and how well it tackled the strong fragrance left by the latter.

I left it running in my bedroom overnight to determine whether it disturbed my sleep. I tested the sound levels using a sound level meter on my phone and assessed the controls and how easy it was to change the filter.

Dreo MC710S air purifier: two-minute review

The Dreo MC710S is part tower fan, part air purifier. It promises both cleaner air and a cooler room with a host of smart features thrown in for good measure. It’s definitely on the larger, heavier side, and its industrial grey/silver plastic finish may not win any beauty contests. But, its height and build are practical and deliberate to make sure it offers the range of features and power needed. 

One such feature is its dual DC motors. These motors push air at a speed of up to 27 feet per second, meaning you can put it at one end of a large-to-medium-sized room and still feel a breeze at the other. The oscillation option, which covers up to 120 degrees, then makes sure this air reaches into the corners of the room (albeit at an oscillating speed that's much slower than I'd like). 

The fan operates in four modes: Normal, Sleep, Auto, and Breeze. The Sleep mode lowers the fan speed and noise, making it barely noticeable at night. The Auto mode adjusts the fan speed based on the room's temperature. As its name suggests, Breeze mode creates a gentle flow of air; this is the default setting for when the purifier is running. Note that you can run the fan without the purifier, but not the purifier without the fan. This is a little annoying when you just want to clear, and not cool the air, but it's a minor complaint. Overall, it compares well to the rest of the best fans on the market.

Speaking of the purifier, the MC710S' dual filtration system includes a pre-filter and a True HEPA filter. This combo captures 99.97% of particles as small as 0.3 microns, making it great for reducing allergens, dust, and other pollutants. During my review, I noticed a significant drop in dust and pollen, and my hayfever was noticeably more manageable. 

There are three purification settings – Low (1), Medium (2) and High (3) – plus an Auto mode that automatically adjusts the power based on the air quality. In tests, the low setting was pretty slow and poor at clearing particulates from the air, yet the high setting was fantastic, clearing dirty air in minutes. The purifier is not as great at getting rid of smells as other, cheaper purifiers I've used like the Levoit 300S, though, so if you’re cooking or have pets, you might still notice some lingering odors.

One of my favorite things about the MC710S is its smart features and remote controls. You can change the settings on the MC710S using the Dreo app, remote control, or through voice commands with Amazon Alexa and Google Assistant. Setting this up is straightforward, and I loved the convenience of being able to adjust settings without getting up. The app shows near-live air quality data and lets you set schedules, which is a nice touch.

The LED touch display on the fan itself is also intuitive, showing all your selected settings at a glance. The unit also features a color-coded light strip that indicates air quality: blue for Excellent, green for Good, orange for Moderate, and red for Poor. This visual cue is handy for quickly seeing the air quality in your room but I'd like the option to enable alerts that warn me when levels are higher than they should be in case I'm not in the room. 

If you’re looking for a multi-purpose appliance that improves your home's air quality and keeps you cool, the MC710S is definitely worth considering. While it's not the most aesthetically pleasing of appliances and lacks some finesse, its performance, smart features, and ease of use make it a worthwhile investment. 

Dreo MC710S air purifier tower fan review: price and availability

• List price: $299.99
• Available in the US

The MC710S is available in the US from Dreo, Amazon and Walmart.

At first glance, the Dreo MC710S's $300 price looks to be on the expensive side. Especially when no other Dreo tower fans exceed $150, and its standalone purifiers top out at $210, for the Macro Max S . In fact, the MC701S is the most expensive product across Dreo's product range.  

However, this price looks more reasonable when you consider that you effectively get two appliances in one; rival products such as Dyson's $649.99 TP07 Purifier Cool or the $550 LG AeroTower Air Purifying Fan are around twice the price; and the MC710S is full of the latest motor and smart tech. 

The most like-for-like alternatives to the Dreo MC710S are the $299.99 Shark HC450, and the $239.99 Hunter HPF500. The Shark model offers a heater function, but lacks Dreo's dual-motor, while the Hunter fan is cheaper because it has fewer speed settings – 9 versus 12 –  and lacks Dreo's smart features, but offers the same HEPA protection.

While $299.99 is far from cheap, it represents good value for money in terms of features, protection, versatility and tech. The smart controls elevate it above many competitors, and with its multi-function design, you don't have to buy or store multiple products.

Dreo MC710S Air Purifier Tower Fan specs

Dreo MC710S Air Purifier Tower Fan review: design

• Bulky, industrial design 
• Digital, color-coded controls

No matter how you look at it, the Dreo MC710S is large, bulky and bordering on ugly with its industrial-looking grey/silver plastic finish. Measuring 46.46 inches x 118cm tall, it's much taller than I was expecting and looks like a tower fan balanced on top of a purifier... which it technically is. The top half of the appliance is where you'll find the controls, LED display and the tower fan portion of the MC710S. Below the tower fan section is a transparent cylinder where the MC710S' dual-motors can be seen spinning, and this cylinder sits on top of the purifier element. 

The touch control icons, and the corresponding remote control buttons, are relatively self-explanatory and (moving anti-clockwise) represent:

• Timer: This button lets you set a timer. Once the allotted time has passed, the fan will automatically turn off. 
• Info: This button get you access to the fan's settings.
• Minus symbol: Used to reduce the fan speed. 
• Power button
• Plus symbol: Used to increase fan speed. 
• Purification mode: This button is used to select what level of purification you need, ranging from Auto up to Level 3. 
• Oscillation: Used to set the oscillation range of the tower fan, from 0° to 120° 

All of your selected settings are then shown on the LED display located at the top of the tower fan, below the touch panel. This display lets you see, at a glance, the room temperature, which purifying and fan modes are enabled, the lifespan of your filter, and the fan speed (when adjusted manually). 

It also features a thin strip of light that changes color based on your room's air quality. A blue light means the air quality is Excellent; green means it's Good; orange warns you when particulate levels are Moderate and higher than they should be; while a red light is an indication that your air quality is Poor.

The remote control features the same icons found on the touch panel. Alternatively, you can control the MC710S using the Dreo app, or via your voice by connecting the air purifier tower fan to your Amazon Alexa, or Google Assistant. 

Setup of these smart features is quick and easy. In fact, setup of the appliance generally takes less than five minutes, including getting it out of the box and removing the plastic cover from the filter. The only slightly lengthy task in the whole process is setting up a Dreo account, but even this is painless.

Elsewhere, there is a carry handle on the rear of the appliance to make it easy to move around, but the bulky shape and hefty, 17.8lbs / 8.1kg weight don't lend themselves well to portability so you're unlikely to move the fan after you've got it in place. 

I typically like to move my purifier into different rooms, depending on my needs i.e I put it in the kitchen when I'm cooking steak or fajitas, or I put it in my youngest son's room at night when the pollen count is high. This is nigh-on impossible with the MC710S. To put this weight into perspective, the Dyson Purifier Hot+Cool Formaldehyde HP09 which is often seen as one of the bulkiest on the market weighs less, at 12.6lbs / 5.5kg. 

With the MC710S, it's clear Dreo has prioritized function over form. It doesn't win any points for subtlety, nor does it blend seamlessly into the background, but it is incredibly easy to set up and use and the extra height and weight helps maximize its performance.

Dreo MC710S Air Purifier Tower Fan review: performance

• Powerful airflow 
• Doesn't reduce odors as well as expected
• Purification speeds vary 

The Dreo MC710S aims to hit the sweet spot between being a powerful fan and an effective air purifier and it almost manages it.

As a fan, the Dreo MC710S works well. It's powered by dual DC motors and pushes air at a speed of up 27 feet per second. This means that if you place it at one end of a large-to-medium-sized room, you’ll feel a breeze all the way across the room, even on the lower speeds. The oscillation feature, which swings up to 120 degrees, then helps make sure the cool air reaches the corners of the room. The fan comes with four modes – Normal, Sleep, Auto and Breeze. 

The Sleep setting lowers the fan speed, and noise. The Breeze setting reduces the power of the air flow, and the Auto setting sees the fan automatically adjusting its speed setting based on the room's ambient temperature. The fan isn't as powerful or effective as an air conditioner, and the oscillation speed is slower than I'd like, but it does a decent job of making a room feel cooler by moving the air around efficiently.

The downside is that the blast of air is almost icy and this can feel a little uncomfortable if you get the angle, speed or distance slightly wrong. It took a fair amount of tweaking and experimenting to find the optimum settings. Talking of settings, the fan can be on without the purifier, but the purifier can't be on without the fan. As soon as your turn the purifier on, the fan runs gently on 'Breeze' mode and oscillates at a default 30 degrees. You can't disable these features. 

I assume that this helps to improve the effectiveness of the purifier, because I don't know why else this would be the case, but it's not always needed and meant that I had to be particular about where I placed the unit so I wasn't cold while the purifier was running. On Breeze mode, as well as on the lower fan settings the fan is whisper quiet. I barely even realised it was on. The noise does increase considerably on higher settings – as high as 69dB on the top speed, which is around the sound of a car running – and this makes it difficult to have on when you're watching TV or similar. Especially if you're the one sat closest to it.

When it comes to air purification, the Dreo MC710S uses a dual filtration system that includes a pre-filter, which traps larger particles like dust and hair, as well as a True HEPA filter. The MC710S promises to captures 99.97% of tiny particles as small as 0.3 microns and this means it can reduce allergens, dust, and other pollutants in the air. My son and I both suffer from hayfever and even on days when there were so-called 'pollen bombs' in my local area, neither of us experienced symptoms to the extent we normally would. This makes it great for people with asthma, allergies or other respiratory problems.

What's more, my kitchen was undergoing a renovation during my review period and the purifier helped remove a noticeable amount of the dust in the air. Even though it wasn't in the kitchen itself, and was in the living room on the other side of the house. It performed less admirably in removing odors, compared to some other air purifiers I've tested such as the Levoit 300S.

There are three purification settings – Low (1), Medium (2) and High (3) – plus an Auto mode that automatically adjusts the power based on the air quality. To test these purifying capabilities, I sprayed deodorant directly at the purifier for five seconds and timed how long it took for the air quality to return to normal on the lowest, and highest settings.  

During the first test, on the lowest setting, the particulate level rose to 880ug/m3. It then took an hour and 15 minutes to return the air quality to normal/excellent. By comparison, on the highest setting it took just 15 minutes to go from Poor (960ug/m3) to Excellent. Interestingly, the purifier continues to take air quality readings even when it's not on, and this is useful for identifying trends and tracking air-quality changes based on certain events. 

I just wish that it would alert me when air quality reached dangerous levels so I could turn the purifier on and clear the room. Or even better, it turned on automatically – from being plugged in but switched off – cleared the particulates and turned off again. I found myself regularly asking "Alexa, what is the PM2.5 of Tower Fan" and becoming almost obsessive about it. A little more automation would give me peace of mind. 

Speaking of voice controls, this soon became my favorite way to control the fan. If I heard a lot of drilling going on downstairs, I could ask Alexa to turn the purifier on and off while upstairs. It let me set timers and adjust the fan remotely, so the room was cool for when my sons got home from school, and I could then track all of these settings on the Dreo app. This convenience goes a long way towards mitigating some of the minor complaints I have about the unit.  

I didn't have the purifier on constantly during the four-week review period. I would use it twice a day – once in the morning and once in the evening – to clear the room, occasionally turning it on at other times, when we had friends over or when the building work was particularly busy. The filter only dropped to 98% during this time. A replacement filter costs $39.99 and Dreo recommends replacing it at least every six months so you need to factor this cost in. 

Overall, the Dreo Air Purifier Tower Fan MC710S does a decent job as both a fan and a purifier. It has its flaws, and there are features that could elevate it from decent to good, or even great, but it works as you'd expect and does what you need it to do.

• Performance score: 4 out of 5  

Dreo MC710S Air Purifier Tower Fan review: voice control

• Easy to set up 
• Adds an extra level of control and personalization
• Perfect when juggling work or the kids 

One of the standout features of the Dreo MC710S is the ability to control it using voice commands via your smart speaker. I have Amazon Echos in a number of rooms across my house and being able to check on the air quality, and control the purifier and fan no matter where I was in my home, was great. 

Once the purifier is connected to your home Wi-Fi, it can connect to any Amazon Echo or Google Home device on the same network at the press of a button through the Dreo app. This app also gives you voice command prompts to get you started, which can be found via Settings and clicking the voice assistant you've connected it to – either Amazon Alexa, or Google Assistant.

You can ask Google or Alexa to turn the purifier on and off and adjust the fan speed – either by asking it to select a specific speed, increasing or decreasing the speed, or setting it to maximum/minimum. You can also ask your smart speaker to set the MC710S to a specific mode – Normal, Auto, Sleep, or Breeze.  By connecting to Alexa, you can also access basic controls via the Alexa app – on/off, fan speed, mode, and display options.

Dreo MC710S Air Purifier Tower Fan review: app

• Offers a range of control options
• Color-coded design is intuitive and simple to use
• Near-live air quality data

The app, as well as using voice commands, is one of my favorite features of the Dreo MC710S. It's intuitive, and everything is well-labelled and clear. An image of the fan sits in the center of the app's home page. If you have multiple Dreo devices you can swipe left and right to access each. Below this image on the left is a clock icon, where you can quickly set the fan to turn on after a set amount of time, plus the on/off button on the right. 

Below the clock icon is the Climate widget that shows the live air-quality levels above the ambient temperature, next to a Schedules widget. In the next row is your current filter life, and the settings menu. 

When the device is on, you can see which mode it's on and whether both the fan and purifier are enabled, or just the fan. Clicking either of these icons takes you to detailed controls page which shows: 

• Mode
• Temperature
• A live air quality reading with corresponding color
• Purification on/off button
• Fan on/off button
• Fan mode controls and speed slider
• Oscillation controls 
• Preferences 

Clicking the Climate widget shows you air quality and temperature readings for the past 24 hours, and 30 days. These readings are shown on a color-coded chart – red for Poor, orange for Moderate, green for Good, and blue for Excellent. As the air quality changes, so does this number and the screen's color. 

Despite the fact these charts deal with some complex information and could be confusing, Dreo makes them easy to navigate and read by carrying through its color-coded system and keeping details to a minimum.

There's a delay of around five minutes in this chart being updated following an air quality change, so it's not hugely useful in the moment, but it's interesting and useful to check after the fact. It's also reassuring to see how the levels change over the day and how well the purifier responds.

How I tested the Dreo MC710S Air Purifier Tower Fan

• I used the Dreo MC710S Air Purifier Tower Fan and its partner app for 4 weeks
• Stress testing different substances
• Experimented with different speeds, modes and settings

I used the Dreo MC710S Air Purifier Tower Fan in the living room of my home for four weeks in peak hayfever season. During which time my kitchen was also being renovated and builders were in the house every day. 

Every morning and evening I used the device to track and manage the air quality, and used the fan on a range of speeds and settings in different scenarios, including when I had friends over. I also experimented with controlling the device using the Dreo app, the physical remote control, and via my Amazon Alexa speaker. 

To test the air purification monitoring and speed, I sprayed a heavy particulate aerosol (deodorant) on the purifier for five seconds while it was in different purification modes and timed how long it took for the air to clear. I also measured the volume with a mobile phone decibel meter.

AiDot Welov P200 Pro review: price & availability

• List price: $159.99
• Available now, but only in the US

The AiDot Welov P200 Pro Smart Air Purifier is available for $159.99 from the AiDot website and Amazon. While reviewing, there was a flash sale on the AiDot website where the price was reduced to $59.99, so it’s worth keeping an eye out for future sales.

The $159.99 price isn’t bad for an air purifier that comes with Matter 1.2 connectivity and useful in-app features. However, value for money is impacted by the fact that the P200 Pro only reports on PM2.5 – particles that are 2.5 microns or less in diameter, such as dust or pollen – so the data provided is nowhere near as detailed as some other air purifiers in this price bracket.

At present, AiDot only supplies the Welov P200 Pro within the US, and it's only available via Amazon US.

AiDot Welov P200 Pro review: design

• Cheap-feeling, flimsy design
• Easy-to-use controls
• Underlighting

The AiDot Welov P200 Pro looks pretty utilitarian – although its dark grey cuboid shape has been jazzed up to a degree by spacing out the ventilation holes into a geometric pattern. It has a square footprint with rounded corners and dimensions of 9.5 x 9.4 x 20 inches. Its dark grey color sees it stand out in the crowd of other air purifiers we’ve tested, which are often white. It's only a shame then, with its decision to opt for a dark color, that AiDot doesn't appear to have used any recycled plastic in the design, since darker plastics are less likely to show any discoloration or impurities that may be present.

Overall build quality feels cheap and flimsy. The unit sounded particularly hollow when handled, and the surrounding panels feel thin and flexed easily. This flimsiness was even more apparent when removing the HEPA filter through the screw-in hatch in the base, which also felt low quality.

The screen on the top of the air purifier uses a mixture of printed-on symbols and LEDs. This is a little different from many of the purifiers I’ve tested, which often rely only on LEDs for the controls. Having permanently visible control symbols is useful, allowing you to find them easily even if the LEDs are off for Sleep mode. Speaking of the touch controls, they’re very responsive and easy to use.

Note that the unit displays a warm white underlight around the base. This could prove useful if the purifier is placed somewhere that it could pose a trip hazard in the dark, for example, but it can be switched off if desired.

AiDot Welov P200 Pro review: features

• Useful app
• Limited IAQ data
• Matter 1.2 connectivity

The AiDot Welov P200 Pro has some useful features for the price, but it’s somewhat limited in areas that we'd expect more when it comes to air purifiers. One of its more nifty features is the Matter 1.2 functionality, enabling it to connect to Alexa, Google Home, HomeKit and others. The Matter QR code for pairing is located on the back panel, and my iPhone 12 Pro had no issues scanning it before subsequently linking it to my Alexa app.

The P200 Pro only detects and reports on PM2.5 – fine particles, such as dust and bacteria – so I was only able to gain part of the story about my indoor air quality (IAQ). There are no readings for microfine particles, such as soot, smoke and some bacteria, nor coarse particles such as pollen, mold and dander. There’s also no measure of the relative humidity, temperature, volatile organic compounds (VOCs), or carbon dioxide, figures that many other air purifiers provide.

The PM2.5 readings themselves didn’t tell me much, but the air quality level was communicated via the indicator light on the top of the purifier’s front panel, and the color of the line in the graph in the AiDot app. I found that the graph wasn't particularly responsive, failing to show the P200 Pro detecting that the IAQ reduced to moderate levels when I conducted a test with dry shampoo. The PM2.5 levels didn’t align during the dust test, either; however, after a while, the graph indicated a brief spike in airborne particulates, although this only reports a level of 25 PM2.5, when the reading direct on the P200 Pro stated 50 PM2.5.

Aside from the less-than-informative graph, I found the app useful for controlling the P200 Pro remotely. I could easily change the fan speed and enable Sleep mode, turn off the night light or display, and enable the child lock. I could also set a timer so that the unit would automatically turn off after a set amount of time, and create automations so The Welov would turn itself on and off without me needing to do anything.

There is an Outdoor Environment section in the app that provides ratings of environmental factors based on your geographical location, rather than monitoring the air via the P200 Pro. Once your mobile device's location has been shared, this section shows the risk of wildfire, the humidity and pollen levels in your area. According to this feature, in Bath, where our head office is based, there's a high level of mold, but low levels of grass, ragweed and tree pollen. Since this feature used my phone's location, I could update this at home, or while out and about. It was interesting to learn which pollen types were the most prolific wherever I was.

AiDot Welov P200 Pro review: performance

• Lowest fan speed is whisper-quiet
• Purified contaminated air in under 2 minutes
• Readings on app don’t often align with display

While the lackf of labs means I can't present any scientific data on the impact of the AiDot Welov P200 Pro on air quality, what I can tell you is the results from day-to-day use and the odd curve-balls that I threw its way – such as bombarding it with dust and dry shampoo.

I found that the Welov P200 Pro wasn’t very sensitive to ambient dust levels; the readings remained low in both the TechRadar reviews office and my home, despite dust being visible in both locations. It was more sensitive than the Shark NeverChange purifier, however, which regularly stated that there were zero levels of PM2.5 in the air. In contrast, the P200 Pro detected small levels at all times. These levels never rose above 5 PM2.5, however, and continuously bounced randomly between readings of 1–5 every two seconds, so I can’t vouch for the reliability of this reading.

I sprayed dry shampoo around the air purifier. This change in IAQ was quickly detected and the reading on the app and the LED screen rose above 350 PM2.5; this caused the indicator light on the purifier to turn red, indicating that the IAQ rating was poor. While the app reading aligned on this occasion, the color reference and classification on the graph didn’t change from "Good", which suggests that the app needs some improvements in order to be considered trustworthy. Since the Welov was in Auto mode, the purifier’s fan sped up to its top speed in response to the presence of dry shampoo, and the reading lowered to 7 PM2.5, within two minutes.

However, our benchmarking air quality monitor was still showing air quality as poor. This was because the P200 Pro can't detect VOCs in the air, only particles of 2.5 microns or larger, meaning that the fan speed reduced as a result of the positive reading, when it ideally should have continued on the higher speed. After manually setting the fan back to max speed, the P200 Pro was able to clear the strong fragrance of the dry shampoo from my bedroom in 10 minutes.

To determine whether the Welov P200 Pro could detect higher levels of dust, I repeatedly kicked up the corner of the rug in our music testing room. This stirred up a fair amount of dust and the purifier detected this increase in about 30 seconds. With the P200 Pro in Auto mode, the fan sped up automatically once the particle levels raised above 50 PM2.5 on the LED screen, and it took the purifier about a minute to bring levels back down to 1 PM2.5.

I tried out the Sleep mode feature overnight and found it sufficiently quiet to not impact my ability to fall asleep. Welov advertises that the P200 Pro can be as quiet as 23dB; on measuring noise levels using an app on my iPhone 12 Pro, I saw a reading of 27dB, which wasn’t as quiet as AiDot suggested; but it wasn’t miles off. Although the Welov was quiet enough, the purifier's sound was a little high-pitched, reminding me of the high-pitched noise of crickets you hear in remote-location horrors, when everything goes quiet right before a jump scare. This wasn't a thought I needed popping into my head at 1am.

On awaking, I didn’t notice that the air felt different to any other morning, which is in contrast to my tests of the Shark NeverChange, where the air felt noticeably fresher upon waking. Personally, I feel this could be due to the very low fan speed in Sleep mode, meaning the rate of air being pulled through is fairly low.

I tested the air purifiers sound levels from the lowest to the highest manual fan speeds. The lowest speed gave a reading of 35dB, which is equivalent to a whisper. Meanwhile, the middle speed registered at 62dB, which is similar to the noise of a normal conversation, and the highest fan speed was 71dB, which is close to the sound emitted by a washing machine.

Welov P200 Pro review: Also consider

How I tested the Welov P200 Pro

• I used the Welov P200 Pro for one week
• I tested it in multiple environments
• I observed its reaction to dust and aerosols

I tested the Welov P200 Pro in the TechRadar reviews office and music testing room, as well as in my bedroom at home.

I monitored how effectively it detected and purified airborne contaminants such as dust and dry shampoo, and how well it tackled the strong fragrance left over from the latter.

I left it running in my bedroom overnight to determine whether it disturbed my sleep. I tested the sound levels using a sound level meter on my phone and assessed the controls and how easy it was to change the filter.
