11 best air purifiers 2024 UK; tried and tested

AIR purifiers do exactly what they say on the tin, cleaning the air inside your home and removing pollutants, odours, gases and even pet hair.

Not only do these clever contraptions provide immediate relief from pollutants, they also offer long-term health benefits. According to the WHO, the air inside homes and offices can be up to five times more polluted than outside due to cleaning products, carpeting, smoke, dust and cooking.

By removing up to 99% of airborne particles, including dust, pollen and pet hair, an air purifier can significantly reduce your risk of developing health issues and help alleviate allergies. 

So how does a purifier work? These machines draw air through a series of filters to remove contaminants and pollutants. The process typically starts with a pre-filter that captures larger particles like dust and pet hair. The air then passes through a HEPA (High-Efficiency Particulate Air) filter, which traps tiny particles such as pollen, mould spores, and bacteria.

Some models also include activated carbon filters to reduce odours. Finally, the purified air is circulated back into the room, improving air quality. 

Old-fashioned air purifiers tended to be bulky and noisy, but nowadays the best models are sleek and almost silent, and some will even connect with your smartphone.

When shopping for an air purifier, keep in mind the size of the space you need to pop it in. Look for a unit with a recommended room size that matches your room's dimensions.

Next, check the type of filter used—HEPA filters are highly effective at trapping fine particles, while activated carbon filters are great for removing odours and chemicals. Noise level is also key: opt for a quiet model if you plan to use your new purifier in a bedroom or office. 

We’ve reviewed options to suit every budget and space, from compact units for small rooms and nurseries to powerful systems suitable for larger open-plan areas, and we reckon there's an air purifier recommended here that’s perfect for every home.

Shark NeverChange5 Air Purifier HP150UK

11

Shark NeverChange5 Air Purifier HP150UK, £249.99

Pros: automatic sensor, long-lasting filter, fresh scent option

Cons: none

Rating: 5/5

This air purifier is super-easy to get going and understand once you're using it.

It's got a handy display that gives you all the information you need quickly and its auto mode means you can set it up in a corner of a room and forget it's there.

We've witnessed it first hand react to cooking odours and high pollen days by stepping up the power and we were very impressed with the results.

Shark backs this purifier to go up to five years without needing to replace the filter, so you'll be saving in the long run.

Filter: DebrisDefence / Medium Particle / Activated Carbon / NanoSeal HEPA Recommended room size: 60m2 Smart app: No

Blueair Blue Max 3250i Smart Wifi 

11

Blueair Blue Max 3250i Smart Wifi Air Purifier, £139 from Amazon

Pros: Quiet, smart phone compatible, air quality display 

Cons: Too large for small spaces

Rating: 5/5

Keep it simple with this efficient and easy to operate air purifier. Blueair’s Blue Max can be paired with a smart phone app or controlled directly from the panel on top and we on test we liked the colour-coded air quality indicator, which, unlike many other models, makes it quick to check that the air in a room is safe.

This model uses a HEPASilent filter and it was indeed one of the quietest machines we tested.

The Blue Max is larger than some compact designs but its smart grey cover should blend in in most homes. 

Filter: HEPASilent Recommended room size: 48m2 Smart app: yes

AX9 Connected Air Purifier 620 m3/h

11

AX9 Connected Air Purifier 620 m3/h, £549.99

Pros: powerful, well designed

Cons: large, expensive

Rating: 4/5

We've tested a number of products from AEG over the years and they never disappoint. This air purifier is a beast and is rated to cover a whopping 129m2; that's bigger than any room in any flat we've been in recently!

And, considering it's a rather large unit (72cm tall, 31.5cm wide) it doesn't stand out too much in a room, with its subtle design that blends into the background.

It's got an extremely powerful filter and you can download AEG's easy-to-use app to control it remotely at the touch of a button.

It's a premium product at a premium price; but, if you've got the money, you won't regret spending it on this.

Filter: Pre-filter & Antibacterial layer & Pre-charged True EPA12 filter & Active carbon and Ionization Recommended room size: 129m2 Smart app: yes

Dyson Hot+Cool 

11

Dyson Hot+Cool Air Purifier, £400 from AO

Pros: Works brilliantly, looks smart, also a heater and cooler 

Cons: Double the price of other decent models, heavier than some units

Rating: 4/5

Dyson’s Hot+Cool may be the priciest air purifier we tested, but it’s also one of the best and the sleekest-looking, too.

This efficient and quiet purifier quickly captures dust, particles and bacteria from the air and doubles up as a room heater and cooler, so if you like the idea of a one-stop-shop for cleaning the air and maintaining room temperature, this could be worth the spend.

We like that it’s quiet, comes with a remote control and oscillates to project clean air around a big space.  

Filter: HEPA 13 Recommended room size: 81m2 Smart app: No

Maxi Cosi Clean 3-in-1 Smart 

11

Maxi Cosi Clean 3-in-1 Smart Air Purifier, £89.99 from Maxi Cosi

Pros: Good looks, compact size, integrated night light

Cons: No recommended room size is given

Rating: 4/5

Maxi Cosi designed their Clean 3-in-1 Smart Air Purifier for use in nurseries, and Goldilocks style, we think it’s just the right size for a smaller room.

A HEPA filter cleans the air efficiently and we love that the Clean doubles up as a night light and even plays lullabies or white noise to help little ones drift off to sleep.

You can control all three options from your smartphone, so this model is great for checking the air quality in a child’s bedroom or for turning on the purifier before you get home from work. Smart, modern looks would work in any home. 

Filter: HEPA13 Recommended room size: n/a Smart app: yes

Vitesy Natede Smart Natural 

11

Natede Smart Natural Air Purifier, £239 from Vitesy

Pros: Lovely natural looks, doubles up as a house plant, silent, no filters required

Cons: Plant not included, still requires maintenance

Rating: 4/5

For something a little different, swap expensive filters for a more natural option and use a plant to purify your room.

The Natede Smart isn’t just a posh plant pot, though, this clever design employs phytodepuration, the ability of plants to absorb air pollutants and transform them into nourishment for the plant itself, to purify the air and water the plant in one go.

We like that you can control the power of the air purifier through your smartphone or by passing your hand over the pot’s control panel.

The filter can be popped out and washed, so no need to keep replacing it. This is also a totally silent option, great if a low hum would annoy you. The Sanseveria plant required isn’t included. 

Filter: Own-brand filter Recommended room size: 20mq Smart app: yes

Vitesy Eteria Personal 

11

Vitesy Eteria Personal Air Purifier, £169 from Vitesy 

Pros: Small size, great for desks, no fiddly filters 

Cons: Limited power

Rating: 3/5

Protect your own bubble with a personal air purifier designed to clean the space around you. Vitesy’s small but mighty Eteria is barely bigger than a pint glass but can still improve the air in a room up to 20 metres square in size thanks to a washable filter (so no expensive replacements are required).

The handy app so you can check air quality anywhere you take the Eteria. This lightweight design has neutral looks and comes in a carry bag; ideal for taking to work to pop on your desk. 

Filter: Own-brand filter Recommended room size: 20mq Smart app: yes

Russell & Hobbs Clean Air Compact 2

11

Russell & Hobbs Clean Air Compact 2, £69.99 from Curry’s 

Pros: Affordable, unobtrusive, great looks, timer

Cons: Small recommended room size, no smart app

Rating: 3/5

While the design of an air purifier shouldn’t be the top of your list of requirements, good looks don’t hurt either, and we think the newly launched Russell Hobbs Clean Air Compact 2 is super smart and eye-catching, with a sleek black or white casing and a wood-effect top dashboard.

A HEPA filter goes to work on pollutants and airborne allergens and on test we liked the three fan speeds (the lowest is pleasingly quiet), and timer that can be adjusted from two to eight hours (although it’s a pity you can’t do this from your phone).

The recommended room size is quite small, though.

Filter: HEPA Recommended room size: 11m2 Smart app: no

Midea SmartAir Pure Control

11

 Midea SmartAir Pure Control, £89.99 from High Street TV

Pros: Efficient, great responsive mode, charcoal filter

Cons: Big and bulky 

Rating: 3/5

Midea’s SmartAir is big and bulky, so it’s only suitable for larger rooms, open-plan living and offices unless you want it to compete with the furniture.

If you don’t mind a bigger design, this is a very efficient option. It quickly purifiers the air in a big space and the MSmartHome app was one of the easiest to use on test.

A charcoal filter whisks away cooking odours and pet smells and we liked Automatic Mode, which measures the air purity in a room and adjusts the speed of the purifier, so you can leave it to get on with its job. 

Filter: HEPA Recommended room size: 36m2 Smart app: Yes

Levoit Core Mini 

11

Levoit Core Mini Air Purifier, £49.99 from Amazon

Pros: Affordable, works with a smart app, aromatherapy option

Cons: Limited room size

Rating: 3/5

The most affordable purifier in our roundup is a popular choice with lots of good reviews, so if you’re a bit discombobulated by the sheer number of air purifiers on the market and the complicated jargon they use, this is a fuss-free purchase.

The Levoit Core Mini may be pocket-friendly but it still ticked the boxes on test, quietly purifying the air in an averagely-sized room using a HEPA filter.

You can also control it with a smart app. On test we loved the unique aromatherapy option; pop your favourite essential oil in to scent your space. 

Filter: HEPA Recommended room size: 17m2 Smart app: yes

Solenco Air Purification Pal

11

Solenco Air Purification Pal, £69.99 from Amazon

Pros: Looks cute, doubles up as night light, affordable 

Cons: Strong smell out of box, not silent

Rating: 2/5

Aimed squarely at use in a baby’s bedroom, Solenco’s Air Purification Pal with night light is the cutest air purifier we tested.

Customise the front with the included stickers before you pop it in a nursery; does your little one prefer a cat with a crown or a friendly tiger?

While this design is marketed for babies and toddlers, there’s no reason why you couldn’t remove the stickers and use the Air Purification Pal in any smaller room in the house.

We had a few little niggles with this model on test: the stickers are fiddly, the purifier does make a low hum, which might not be suitable for babies easily disturbed by noise, and the purifier has a strong plastic-y smell straight out of the box (but this does dissipate with time). 

Filter: HEPA13 Recommended room size: 10m2 Smart app: no

How we tested out these air purifiers

We tried out each of these air purifiers continuously for two days in different rooms of a standard family home.

We looked for ease of setup and use, simple filter changes, low noise levels and good looks, as well as a noticeable difference to the air around us. 

Why do I need an air purifier?

An air purifier improves indoor air quality by removing pollutants, allergens, and toxins. It reduces the risk of respiratory issues, allergies, and asthma by filtering out dust, pollen, pet dander, and mould spores.

For those living in areas with high pollution or suffering from allergies, an air purifier can offer significant health benefits.

They also eliminate unpleasant odours. Do you absolutely need an air purifier? No – but if you live in a city, suffer from allergies or just want to ensure that your family’s indoor space is safe, they can be worth the spend. 

How do I use an air purifier? 

Using an air purifier is pretty straightforward. First, choose the right size for your room. Position the purifier centrally, ideally away from walls and obstructions, for good airflow.

Keep doors and windows closed while running the purifier to prevent outdoor pollutants from entering. For best results, run the purifier continuously; four hours is recommended as a minimum.

Regularly replace filters according to the brand’s recommended schedule if required; typically every three to six months.
