Along with the best air fryers and the best coffee machines, air purifiers are becoming a must-have gadget for modern living. As we pay more attention to air quality both inside and outside our homes, the best air purifiers can be a godsend, particularly if you suffer from hay fever or have pets.

The job of an air purifier is to clean the air inside our homes by detecting and trapping tiny pollutant particles, such as dust, pet dander (the animal equivalent of dandruff), pollen, smoke and even unwelcome odours. It does this using high grade filters that can trap even the tiniest particles.

Our experts at the Good Housekeeping Institute tried a range of leading air purifiers to find the best for your home. Keep scrolling for our full reviews, but here they are in one handy list.

Best air purifiers 2025


If you’re replacing an existing air purifier, there are plenty of places for you to safely recycle your old one. Find your nearest electrical recycling point, or read our guide on how to donate or dispose of your appliances and tech for extra guidance.

How do air purifiers work?

These clever gadgets use two different filters to clean the air thoroughly, with most air purifiers claiming to remove over 99% of nasties from the air.

The first filter is usually a larger one that can be rinsed, dried and reused, and is not too dissimilar from those you find in the best cordless vacuum cleaners. This deals with the larger particles, such as dust and hair.

The second filter is much smaller and can't be washed, which means it’s disposable. On the positive side, depending on how much you use your machine, it should last a good six months.

It's this filter that catches smaller particles in the air. Some are known as a high-efficiency particulate air filter (HEPA) and filters that meet these standards can catch even the most microscopic of dust particles – generally as small as 0.3 microns, but some Dyson models claim to catch ones that are just 0.1 microns.

How to choose an air purifier

The requirements of a good air purifier are simple – it needs to improve the air quality within your home, as quickly and quietly as possible.

Features: To find the right air purifier, you need to decide what you want it to do. That may sound obvious, but the Dyson Purifier Hot + Cool not only purifies air, but also cools and heats it. And if you have a specific type of allergy, you'll want a purifier that really will pick up all those minuscule particles.

Noise: If you’re going to use your air purifier at night, look for a quiet model, especially if you’re a light sleeper.

Portability: You'll need to decide where your device is going to live and whether you're going to want to move it frequently. If so, make sure it's easily moveable and isn't too heavy.

Size and reach: Check the size of the room it's going to purify. This matters hugely, as you need to ensure the machine you buy can tackle the entire space. Some can purify rooms as large as 135m squared, while others only stretch to areas measuring 10m squared.

Wattage: Generally, the higher the wattage, the more energy intensive a product will be. The amount of energy a purifier consumes equates to how much it will cost to run per hour.

Our experts tested the energy consumption for all the models below, running them for an hour on their highest setting, and found that none used more than 1 pence of electricity in that time.

How we test air purifiers

best air purifiers
Hannah Mendelsohn

To find the best air purifiers, the Good Housekeeping Institute experts assessed how easy each model was to set up and use, as well as its overall design and efficiency. They also analysed each product's size, weight, portability, noise levels (especially at night-time) and the size of room it could purify.

When it comes to how well air purifiers do their main job – cleaning the air – our experts carry out three tests. The first looks at how quickly each air purifier cleans the everyday air of our test room, replicating how it would operate at home when you haven't got any candles lit, windows open or food cooking.

Then the testers disperse a mixture of dust and ash into the space and measure how well the air is cleaned at intervals of 30 and 60 minutes. Finally, they spray deodorant into the room for a set amount of time and again measure how well the particles are removed from the air.

Measurements are taken using an air quality monitor that detects fine particulates known as PM2.5 (often created by the combustion of fuel), and coarser, but still inhalable ones known as PM10 (dust and pollen fall into this category).

Finally, each device was trialled by a panel of experienced purifier users who reported back on whether they noticed any changes in air quality when using it at home.

Read on for our experts' pick of the best air purifiers.

Best air purifier

Dyson Purifier Big+Quiet Formaldehyde

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Purifier Big+Quiet Formaldehyde

Pros

  • Easy to set up and use
  • LCD screen tracks and reports changes in your room's air quality
  • Cleanses air quickly and responds to changes in quality automatically

Cons

  • Heavy and bulky

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.

AEG Pure 5000 Compact Air Purifier for Home

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Pure 5000 Compact Air Purifier for Home
Now 30% Off

Pros

  • Responsive controls, clear display and simple instructions make it easy to use
  • Relatively lightweight, making it portable despite a lack of wheels
  • Panellists were impressed with its odour elimination

Cons

  • Expensive replacement filters (£69.99)

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.

Molekule Air Pro Air Purifier

Air Pro Air Purifier
Now 15% Off

Pros

  • Outstanding air purification performance on test
  • Modern look shouldn't stand out too much around the home
  • Intuitive and informative accompanying app

Cons

  • Heavy

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.

Molekule Air Mini+

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Air Mini+

Pros

  • Compact yet powerful
  • Good length cord and handle making it easy to move from room to room
  • Excellent performance during our test cleaning everyday air, especially for its size

Cons

  • Slight lag when selecting power levels (in comparison to its more advanced version)

Score: 94/100

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.

Pros

  • Sturdy and stable
  • Range of fan speeds
  • Intuitive controls and seamless in-app connectivity

Cons

  • Run time can only be controlled via the app

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.

Blueair Blue Max 3350i

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Blue Max 3350i

Pros

  • Detailed instructions means set-up is a doddle and done in a couple of minutes
  • Easy to switch between fan speeds and modes
  • Sturdy but also fairly portable

Cons

  • The cable isn't that long, which could make it tricky to find the right spot

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

Dyson Hot+Cool Formaldehyde Purifying Fan Heater

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Hot+Cool Formaldehyde Purifying Fan Heater

Pros

  • Intuitively designed controls
  • Relatively lightweight to pick up and move
  • Compatible with the MyDyson App and voice control for easier use

Cons

  • Expensive (although cheaper than our winning Dyson)

Score: 93/100

This Dyson's versatility hugely impressed our panel, as it's able to blow both hot and cool air, as well as purify. Its multi-purpose design means it saves on having to store three large separate machines, and no one can argue with the brilliance of that. As for its purifying prowess, it proved a trusty buy, whether facing ash or deodorant, leaving the air cleaner after an hour than it had been before we started both tests.

Testers liked the way it creates an air quality report for you to monitor in real time on the LCD screen. It's also straightforward to operate, thanks to a remote control and app. And it ranked as one of the most energy efficient machines on test, using a mere 0.003 kilowatts running on its highest setting for an hour – that's less than one pence.

Though expensive, you do get three products in one. If you're planning to sleep with it on, note that it got noisier on speed settings six to ten.

Shark NeverChange5 Air Purifier HP150UK

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
NeverChange5 Air Purifier HP150UK

Pros

  • Quick at cleaning air on test (just our intensive deodorant test took a while)
  • User-friendly

Cons

  • While small, it’s not the most portable design
  • Touch screen sometimes slow to respond

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.

Russell Hobbs Clean Air Compact Air Purifier RHAP1001B

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Clean Air Compact Air Purifier RHAP1001B

Pros

  • Sturdy despite compact design
  • Clear instructions and simple to set up

Cons

  • Less energy efficient than others on our list (although still only used about one pence of electricity an hour)

Score: 92/100

Designed for smaller spaces such as home offices, this mini air purifier can easily move from room to room as and when you need it, making it a good buy if you want one close by at all times.

Testers found it was better at removing larger PM10 (e.g. dust and pollen) than PM2.5 and when they tested it with deodorant, it didn't return the particulate levels down to what they were beforehand within an hour. That said, our experts create a worst-case scenario and it still left the air a lot cleaner.

Our testers praised the device's LED display with touch sensitive buttons, but they'd have liked an air quality indicator, which most other models have. Some noticed a little condensation on their windows, too.

Russell Hobbs Clean Air Mini Aroma

Clean Air Mini Aroma

Pros

  • Controls are well-placed and simple to use
  • Design is great for small spaces

Cons

  • Short power cord may make placement tricky
  • No handles to help with portability (and while it's small, it may be too big for some shelves, so check measurements before you buy)

Score: 86/100

There’s something spa-like about this minimalist air purifier from Russell Hobbs, making it our top pick for soothing you to sleep. It’s quiet, and while it’s busily (and effectively) cleaning the air around it, it can also disperse essential oils via a hidden aroma pad. Testers found this feature was fiddly to access at times, but once they added a few drops, the scent would linger for a long time.

Back to its main job, it was easy to set up and removed dust, ash and deodorant from the air quickly, leaving the room feeling notably fresher. While lightweight and relatively compact, it proved sturdy too. Time to plug it in, add a few drops of lavender oil, and drift off.

BlueAir ComfortPure Most Powerful 3-in-1 Air Purifier

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
ComfortPure Most Powerful 3-in-1 Air Purifier

Pros

  • Multi-functional for year-round use
  • Sleek, space-saving design
  • Seamless in-app connectivity

Cons

  • Expensive
  • Slower to purify

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.

Solenco Purification Pal

UK Approved(Esquire,Red,HB,GH,Country Living,Prima)
Purification Pal

Pros

  • Buttons are well-located and responsive
  • Scored well when clearing everyday and deodorant particles

Cons

  • It's not immediately obvious how to dismantle the purifier
  • Must be one metre from walls, which could create a trip hazard for little ones depending on positioning

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.

The verdict on air purifiers

If budget is no object, then our joint winning Molekule Air Pro Purifier is sleek and achieved full marks in all our air purification tests.

For something more affordable, the AEG Pure 5000 Compact Air Purifier was rated as "exceptional” by our experts and costs over £600 less, although you'll have to bear the cost of its replacement filters in mind (£69.99 each).

Our best air purifier under £50 is the Russell Hobbs Clean Air Mini Aroma. It’s effective but it is a smaller device, making it better suited to more compact rooms.
