9 best air purifiers for a cleaner, healthier home in 2025

Score: 98/100

Our winner is a real statement buy. Dyson’s latest model was developed to purify larger spaces than its predecessors, and it impressed on design (it’s big yet sleek) and performance, removing most of the particles our testers threw its way quickly and effectively. In fact, from dust to deodorant, it aced all our tests in the lab and at home, and our pet-owning panel tester found it removed animal dander effectively too.

Our panel liked its unique ‘breeze mode’, which mimics the feeling of being outdoors, and you can angle its air flow to suit, too. Its auto mode also deserves a special mention for its responsiveness, ramping up purifying efforts immediately when our tester started cooking,

As with most Dyson products, it’s the detail that truly sets it apart; it has hidden wheels to make moving it around easier (although it’s still heavy and probably too big for smaller homes), and its app is intuitive and informative. Everyone found it quiet too and it used minimal electricity on test. It’s a serious investment, but it barely dropped a mark on test and has style in spades, so if you’ve got the budget and space, it shouldn’t disappoint.

We've also tested this air purifier's more premium counterpart – the Dyson Purifier Big+Quiet Formaldehyde BP04, awarding it one of our 2024 Good Housekeeping VIP Awards. It has a souped up filter that claims to remove more NO2 and a CO2 filter. It's just as high-performing, but with an even higher price tag.

Score: 96/100

This compact, slate grey air purifier boasts lots of innovative features including a breeze filter, which AEG claims will remove 99.97% of pollutants from the air, an ‘active carbon layer’ to absorb cooking and damp dog smells, and an odour sensor designed to detect and reduce any hazardous gas or solvents in the air.

It also has a ‘night mode’ that automatically dims the LED display and powers down the fan when you’re ready for sleep, and it connects to the AEG Wellbeing app so you can monitor filter usage.

This device definitely lived up to its impressive billing – our experts liked the chic design, clear display, responsive controls and easy-to-follow instructions. When it came to performance, they rated it “exceptionally good” at filtering normal air and removing dust and ash. It was also quiet in use, even on its highest setting. Our panel liked being able to see a graph of the machine’s progress, and praised the “stealthy” night mode.

The filters aren’t the cheapest and it doesn’t have castor wheels for moving around, but due to its compact design, this shouldn’t be too much of an issue.

Score: 96/100

This sleek air purifier achieved full marks for all three of our air quality tests – it’s seriously effective. Really, we could leave our review there. But, like our winner, this is another premium buy with a price tag to match, so we think it's worth exploring the features.

Testers liked how intuitive it was to set up and use, whether they controlled it via the app (where you can access detailed information about your air quality) or by voice. There are six settings, plus an auto one that will detect changes in air quality and adjust its power accordingly. At its max, it’s not the quietest, but it was barely noticeable on its lowest setting, recording 39dB in the lab, which is similar to the ambient noise of a library. So, it’s a good one for bedrooms too.

Finally, a note on its filters because won't see a reference to HEPA in the specs below. That’s because Molekule has created its own unique ones, which it says not only collect particles but destroy them too (including mould). This has been tested and approved by the FDA (Food and Drug Administration) in the US for added peace of mind. It’s an impressive buy.

A compact version of the model above, this is elegant and very effective. Despite its smaller stature, it cleared dust, ash and aerosol pollutants with ease, improving our air quality to better levels than when our experts started. It wasn’t quite as powerful as the Air Pro, but the difference was very small.

Set-up was easy, thanks to the clear instructions (which was helpful, as the on-purifier controls took a bit of deciphering), and it has the same intuitive features as its larger counterpart. The strong handle makes it pleasingly portable, and the filters are easy to fit and remove.

It’s an investment though, and, when on maximum power, testers recorded highs of 70 decibels. But with five settings to choose from, you should be fine to run it at night without disturbing your sleep.

Score: 94/100

Looking for an air purifier that’s compact, efficient and smartly designed for smaller living spaces? This BlueAir model ticks all the boxes – and then some.

Despite its smaller footprint, it proved itself a powerful performer, scoring full marks when tackling high-pollution areas in the home. Its compact design makes it easy to tuck into corners or behind furniture, without compromising airflow or accessibility. The interface is clear and well-thought-out, with three fan speeds and two distinct modes (standard or night), which are all easy to navigate using the device’s responsive controls.

Its seamless app connectivity also sets this model apart. The BlueAir app pairs easily via Bluetooth and Wi-Fi; and, once connected, you can control fan speeds and modes and schedule the device to turn on or off at specific times. Sleek and reliable, this purifier punches well above its price tag.

Score: 93/100

With its pared-back style, straightforward set-up and intuitive app control, this air purifier should fit right into any home. Testers liked the detailed manual, its range of three fan speeds and quiet night mode. It’s also lightweight, which means moving it around isn’t too much of a struggle, despite a lack of handles.

When it came to performance, it quickly started cleaning the air in our lab, returning it to a healthy level within half an hour. It’s also quiet in use. Our panellists at home said it made a noticeable difference to their air quality, including one hay fever sufferer who found it improved the quality of his sleep.

We’ve tested this whole range from Blueair. At a glance, here are their scores and what sets them apart:

• Blueair 3250a: Scored 92/100 and designed for rooms of 48m2; lacks app compatibility
• Blueair 3250i: Scored 91/100 and designed for rooms of 48m2
• Blueair 3450i: Scored 87/100 and designed for rooms of 103m2

Score: 92/100

This air purifier has built-in anti-odour technology, which releases a fresh floral and citrus scent so your air is both cleaner and sweeter-smelling. Testers found it worked well and liked the effect. In terms of air quality, it removed dust and pet dander from our test room very quickly but took longer to deal with deodorant particles.

Our experts praised its clear control panel and sizeable air quality display. They found it easy to set up too, and thought the instructions were helpful (there’s a start-up guide in the box with the rest accessible online). But it’s not the most portable, as there’s no handle or obvious area to grip onto.

There’s a good selection of modes, timers and air speeds though, so you can tailor it to your home. And the filters are designed so that you only need to change them up to every five years. They were simple to fit and remove for cleaning too.

For even bigger spaces, there’s also a MAX version, which caters to spaces measuring up to 130 square metres.

Score: 86/100

The BlueAir ComfortPure 3-in-1 T10i is a versatile, compact air purifier that also doubles up as a heater and fan, making it a top choice for smaller households where space saving is a priority.

This device impressed with its user-friendly features and in-app connectivity, which allows you to control fan speeds, modes, and real-time pollutant monitoring from your phone (we found the timer feature, which estimates the time needed to bring levels down to a healthier range based on the current mode, particularly helpful).

It performed well as a heater; combined with adjustable fan speeds, oscillation and a timer, it offers great flexibility for colder weather (though it may struggle to heat larger, open spaces). On the flip side, the fan mode promises welcome relief on those warm summer nights – scoring full marks for both airflow range and control. Sound levels ranged from 38.7 dB at the lowest setting to 61.4 dB at the highest, which, while not whisper-quiet at full blast, is a reasonable trade-off for its powerful airflow.

Whether via the app, remote control, or the device itself, adjusting settings was quick and intuitive. Filters were also easy to fit and remove, and we appreciated its thoughtful design features (think: ergonomic controls, sturdy construction, and comfortable strap handles for portability), though, like other Blueair products, the lack of a direct UK contact number for support can be frustrating.

Score: 81/100

Designed specifically for children’s bedrooms (and with customisable stickers included), this air purifier also has a UV nightlight. It runs quietly in the background and reached a maximum volume of just over 48dB in our lab, which is quieter than the 54 advertised. It performed well across all our testing, particularly in our deodorant test. Dust and ash were cleansed effectively too; it just took a bit longer to remove all the particles our experts introduced.

It’s fairly bulky, which means it may not blend in with your overall decor. And there’s no handle, so while it’s not heavy, it is a bit of a faff to move around. Our testers also flagged that the machine doesn’t arrive ready to plug in and go; you need to remove the filter from its packaging. This is mentioned in the instructions, but it’s not obvious otherwise.
