The best air purifiers help to improve your health at home, thanks to their ability to trap and neutralise airborne pollutants, pollen, dust mites and pet dander. This helps reduce sneezing, makes it easier to breathe, and minimises flare-ups from allergies and irritants.
Air purifiers are sleek, quiet and packed with innovative features. Many offer app or voice control, air quality readouts, and sleep modes with ambient lighting, which is ideal for bedrooms and nurseries.
Some newer models go further, using smart home AI integration and sensors to continuously analyse air quality, creating patterns of use that save energy when you’re out, and working harder to clean the air when you’re at home. This tech is particularly handy if you live near a busy road, have a keen cook in the house, or like a wood-burning stove in the evenings.
There are a few other things to know when choosing an air purifier. HEPA filters remain the gold standard for capturing around 99.97 per cent of airborne particles, while activated carbon filters can target odours and gases. UV-C light and photocatalytic filters can kill bacteria and viruses. But new filter technologies are also starting to make their way onto the market, with some lasting as long as five years.
But that’s a lot to consider. That’s why I’ve found the best air purifiers through rigorous testing. Whether you're looking to relieve allergies, freshen up pet-filled rooms, or just want peace of mind that your indoor air is as clean as possible, there’s an air purifier to suit every home and budget.
How I tested
For context, I’m an allergy sufferer. I have hayfever and am constantly looking for ways to alleviate my symptoms. As such, I’m the perfect candidate for this test.

I tested each of these air purifiers within my home, trialling all the settings to get a full picture of performance. I assessed the following key metrics:
- Air quality: I used an air quality monitor to get real-time data on air particles and VOCs (volatile organic compounds) during testing. The best air purifiers remove these unwanted pollutants. I also timed the air purifiers as they cleaned the air to see how quickly they made a difference.
- Allergies and sensitivities: I assessed health and hygiene. Did I still get the sniffles if the air purifier claimed to be able to suck up allergens?
- Noise: I used a decibel metre to measure the noise of these air purifiers. The best models are so quiet that you barely notice them, allowing you to keep them running overnight.
- Ease of use: I assessed how easy each air purifier was to use, and assessed the performance of its smart features like air monitoring.
- Style: Most air purifiers need to be out on display, so I looked for functional but fashionable appliances that won’t ruin your interior design.
- Value for money: I considered the initial cost of the air purifier, as well as how much the filters are to replace and the cost of running the machine.
Not all of the models that I tested made the final list, so below are the best air purifiers you can rely on within your home.

Levoit core 400S air purifier
Best: Air purifier overall
CADR: 400 cubic metres per hour

Weight: 5.8kg
Energy consumption: 36W
Warranty: 2 years
Noise level: 24-60dB
Filter type: Pre-filter, filter, activated carbon filter
Why we love it
- Good app integration
- Fast air-purifying
- Quiet
Take note
- No longer uses a HEPA filter
The Levoit core 400S air purifier ticks a lot of boxes, so it’s no surprise that I found it to be the best air purifier overall. It was quick at purifying the air in my home, even in large spaces. But it’s also unbelievably quiet – even on the highest speed setting, I could barely hear it at all.
It uses a three-stage filtration system, which includes a pre-filter for larger particles, a primary filter for dust and mould, and an activated carbon filter for odour reduction, which is excellent at reducing smells from cooking or pets.
I found the automatic mode neat, cleaning the air without intervention. It’s a remarkably responsive machine, speeding up when it detects particulates and slowing down when the air is clean. It’s so responsive, in fact, that it even ramped up the power whenever my dog walked into the room.
I also loved the smart functionality – it was great being able to set up scenes in the VeSync app, turn on the air purifier before I even entered my home, and use Alexa to turn it on when I was too lazy to get to the unit. Best of all? It’s very affordable for the sheer value it delivers, although the replacement filters can be pricey.

Coway airmega 50 air purifier

Best: Budget air purifier
CADR: 120 cubic metres per hour
Room size: Up to 31 sq m
Control: Auto, touch, smart air sensor
Dimensions: 17cm x 17cm x 32cm
Weight: 1.6kg
Energy consumption: Up to 14W
Warranty: 2 years
Noise level: 18-44dB
Filter type: Pre-filter, filter and deodorisation filter
Why we love it
- Air quality indicator
- Features night light
- Filters last for eight months
Take note
- No wifi or app control
- Not as effective on lower modes
If you're looking for a quiet, compact air purifier on a budget, the Coway airmega 50 air purifier is hard to beat. Designed with smaller spaces in mind, this unit is light enough to move from room to room, yet powerful enough to clean up to 31 square metres, making it just about right for every room in the average British home.
What I liked most during testing was the real-time air quality indicator, which uses a coloured light to show how clean the air is (blue indicates good, green for moderate, amber for bad and pink for very bad). It’s a small touch, but one that gives instant reassurance.
It’s also a great option for kids’ bedrooms thanks to the built-in nightlight, which gives off a gentle glow that’s ideal for relaxing bedtime routines or little ones scared of the dark.
The Coway airmega 50 air purifier has a smart sensor that automatically adjusts the fan speed depending on the air quality. It’s also incredibly quiet on its lowest setting, so it’s great for overnight use.
While it doesn’t come with app connectivity or wifi features, the filter lasts eight months, and the unit uses very little power, making it energy-efficient enough to leave running for extended periods. Just bear in mind it’s most effective on its higher settings – so if you live in a high-traffic area, you might want to run it at full speed before bedtime.
Overall, this is a brilliant choice for those on tighter budgets. There are still cheaper options – the Daewoo purifier below, for instance – but those models only work on fairly small rooms. For most homes, this is the best budget air purifier.

MeacoClean CA-Hepa 76x5 wifi air purifier
Best: Air purifier for large rooms
CADR: 360 cubic metres per hour
Room size: Up to 53 sq m
Control: App, touch button
Dimensions: 49.7cm x 30.3cm x 27cm
Weight: 4.6kg
Energy consumption: Up to 50W
Warranty: 2 years
Noise level: 25-56dB
Filter type: HEPA H13, activated carbon
Why we love it
- App lets you see the air quality outside
- Powerful filtration for large rooms
- Real-time air quality monitor
- Great for pet owners and hay fever sufferers
Take note
- Can be noisy at higher fan speeds
With its sleek white casing and high-performance filtration, the MeacoClean CA-Hepa 76x5 wifi air purifier is a solid pick for larger households or anyone battling indoor allergens. It uses a multi-layered HEPA H13 and charcoal filter, UV-C sterilisation, and an ioniser to tackle everything from pollen to cooking smells. With a 360 cubic metres per hour CADR, it’s powerful enough to clear the air in an open-plan space or large living room.
It’s not so heavy that you can’t move it from room to room, and it comes with a sturdy handle, making it easy to transport. You can control it via the Meaco app, which is easy to set up and shows real-time air quality readings, local weather and even energy usage. You can also switch between modes or fan speeds on your phone, or simply use the nicely designed touch-control pad at the top of the device.
It also comes with an ‘anion’ function, which releases negative ions into the air. These tiny charged particles stick to dust, pollen, and smoke in the air, causing them to clump together. This helps the air purifier catch them more easily in its filter, or they fall out of the air and onto the floor, making the air cleaner and easier to breathe.
So, if you’re looking for a high-performance purifier with app control and advanced filtration technology, the MeacoClean 76x5 ticks all the right boxes.

Levoit core 600S smart air purifier
Best: Smart air purifier
CADR: 400 cubic metres per hour
Room size: Up to 83 sq m
Control: Touch panel, app, Alexa/Google voice
Dimensions: 27.4cm x 27.4cm x 51.9cm
Weight: 5kg
Energy consumption: 24W
Warranty: 1 year
Noise level: 24-48dB
Filter type: 3-stage true HEPA H13 and carbon
Why we love it
- Impressive air cleaning for the price
- App shows real-time PM2.5 levels
- Sleep mode and auto mode for hands-free use
Take note
- A little bulky for smaller rooms
- Filters aren’t cheap
The Levoit Core 400S punches so far above its price point that it could well be a contender for the crown of best air purifier, if only it didn’t feature such a run-of-the-mill design.
Offering excellent filtration and smart features you’d usually only see on more expensive models and a three-stage HEPA H13 filter, it captures 99.97 per cent of airborne particles down to 0.3 microns, including smoke, pollen and pet dander. A carbon layer also tackles odours and VOCs, making it a great choice for allergy sufferers, pet owners or city dwellers.
Real-time air quality is shown through a coloured light ring on top of the purifier, while the app gives you scheduling, timers and remote control. There’s also support for Alexa and Google Assistant if you prefer voice control.
In my at-home tests, the core 600S cleared up to 99.9 per cent of PM2.5 particles within half an hour – even after match and smoke tests – with barely a whisper on its lower settings. The sleep mode is practically silent, while auto mode adjusts the fan speed to one of four, depending on air quality.
One downside is the app, which I had to reinstall twice when it froze during use. Plus, it only works on a 2.4Ghz network, so you might need to use your phone as a hotspot. But if you can forgive the odd hiccup and aren’t bothered about setting complex schedules (you can still set timers of up to 12 hours using the touchpad), the 400S is one of the best-value smart air purifiers around. Be warned, the filters aren’t cheap at £66.99 (Levoit.co.uk), although you may find them cheaper elsewhere.

- Charges your mobile phone or earbuds
- Easy to control via the SwitchBot app
Take note
- Can get noisy at maximum fan speed
- Wouldn’t charge my Fire tablet
- Limited to 2.4 GHz wifi
This model is designed to double up as a side table, so it wins first prize for thinking outside the box and making an air purifier multi-functional and genuinely practical. It’s a brilliant solution for smaller spaces, and works well in living rooms, bedrooms, or home offices.
A favourite feature is the pull-out aroma pad drawer for essential oils, which adds a subtle scent to your room without needing a separate diffuser. The ambient light ring is another nice touch, glowing green, orange, or red to reflect current air quality. You can also customise it to any colour you want via the app, which also lets you easily check your air quality and tweak settings from your phone.
The air purifier includes a PM2.5 sensor for monitoring fine particles, and it’s compatible with Matter, Apple Home, Google Home, Alexa, and more. That means you can control it via voice commands, routines, or automation.
It also doubles as a wireless charging station, handy for keeping your phone or earbuds topped up overnight. That said, I found it a bit slow, and it didn’t work with an Amazon Fire tablet, so don’t expect lightning-fast charging speeds. Still, it’s a thoughtful bonus that adds extra value.

Best: Value air purifier
CADR: 240 cubic metres per hour
Room size: Up to 63 sq m

Weight: 3kg
Energy consumption: Up to 35W
Warranty: 2 years
Noise level: 20-52dB
Filter type: Pre-filter and filter and deodorisation filter
Why we love it
- Auto mode with real-time air quality sensor
- Features mood light
- Filters last 12 months
Take note
- No wifi or app control
- Higher price than similar-sized models
Coway is known for its premium air purifiers, and the airmega 100 lives up to the hype. Designed to sit discreetly in bedrooms, living rooms or even home offices, it includes a smart air quality sensor that constantly monitors your indoor air and adjusts the fan speed accordingly.
The LED ring on the front glows blue, orange or red depending on the current air quality, which is a handy way to get a visual on your data without fiddling with buttons or apps. I also liked that it powered up straight away when I burned some matches or sprayed deodorant during testing, returning my home’s air quality to ‘good’ in less than 20 seconds.
There’s no app or voice control, which feels like a missed opportunity in a premium device. But it does what it sets out to do — it cleans the air quietly and effectively. Plus, the filters last 12 months, which is twice as long as many other big brands, and they’re around half the price too, so it’s more cost-effective in the long term.

Blueair blue mini max air purifier

Dimensions: 17.2cm x 17.2cm x 28.9cm
Weight: 1.4kg
Energy consumption: 2-10W
Warranty: 2 years
Noise level: 26-46 dB
Filter type: HEPA silent, carbon
Why we love it
- Whisper quiet
- Energy efficient
- Washable fabric pre-filter in different colours
Take note
- No smart features
- No auto mode
The popular Blueair blue mini max air purifier is simplicity done right. With a stripped-back one-button control and customisable fabric pre-filters in colours like grey and brown, it resembles a Scandi-style music speaker more than an air purifier.
Small enough to fit on a shelf or move from room to room, its compact footprint is ideal for smaller rooms and flats, where bulky purifiers can take up valuable space.
Despite its diminutive size, I was impressed by the mini max’s power. With 100 CADR and Blueair’s patented HEPA silent technology to capture particles and reduce noise, it reduced 0.3-micron particles by more than 50 per cent in half an hour in my kitchen after cooking, noticeably reducing the smell of fried onions and garlic.
This is a very popular air purifier, but it didn’t reach the top of my list because no app or smart home compatibility. There’s also no auto mode to cope with sudden decreases in air quality, which other cheaper models include as standard.
However, this could be a winner if you’re after something that’s plug-and-go. It’s also quiet enough for bedtime use, making it a good option for light sleepers or nursery rooms.

Why we love it
- Compact and easy to move
- Good value for money
- Simple to control
Take note
- Suitable for smaller rooms only
- No app or smart features
Ideal for smaller rooms, Daewoo’s air purifier is one of the most affordable HEPA air purifiers out there. While you don’t get smart features or app connectivity, it covers the basics at a decent price. You get three fan speeds and three timer settings, as well as an optional night light.
The air purifier’s compact design means it's light enough to move around the home with ease, and it won’t take up much space, so it’s ideal for dressing tables, shelves or bookcases. At its lowest fan speed, it registers just 30dB, making it a good option for a nursery, bedroom, student accommodation or home office. It’s also energy efficient, costing less than 1p an hour to run (at the time of writing).
Of course, it’s a pretty no-frills option. There’s no real-time air quality data, no timers or modes, and you’ll need to remember to manually turn it on and off, unless you use the timer. It also won’t be powerful enough for bigger rooms. However, if you just want something simple to freshen the air in a small space, this Daewoo model does the job without breaking the bank.

Shark neverchange 5 air purifier
Best: Air purifier for bad odours
CADR: 60 cubic metres per hour
Room size: 60 sq m
Control: Extra cost
Dimensions: 38.5cm x 23.7cm x 26.6cm
Weight: 3.32kg
Energy consumption: 26W
Warranty: 2 years
Noise level: 35dB
Filter type: HEPA, medium particle, activated carbon
Why we love it
- Filter only needs changing once every five years
- Has add-on anti-odour cartridges
Take note
- No app support
- Looks a bit weird
While it’s not the best-looking machine, Shark’s neverchange 5 air purifier worked wonders in my kitchen. It was one of the most effective models for zapping odours, and it left my kitchen smelling surprisingly fresh, even after cooking a chicken curry and chopping onions. It works so well because it features some sweet-smelling anti-odour cartridges. You can choose between different strength settings, and the cartridges last a couple of months. It’s a great touch, and it’s not particularly overpowering.
As for the purifier itself, it removes allergens, mould and bacteria, cleaning the air and circulating it through the room after multi-stage HEPA filtration, including a carbon layer, together capturing 99.97 per cent of pollutants and allergens down to 0.1 microns. The display even shows the size of each particle it removes.
The auto mode adjusts the fan speed to suit the air quality and turns off when the air quality is perfect, and the built-in sensors track changes in the air in real time. The digital display reports the percentage of clean air, the time left to clean and the particle amount, so you can be confident the air is as clean as it can be.
The biggest perk of the model is its filter. Shark says the filter will last a whopping five years before it needs replacing. That’s fantastic and blows the competition out of the water. Accurate? I’ll have to take Shark’s word for now. The only real downside is that it doesn’t have an app – everything has to be controlled using the buttons at the top of the machine.

This is a compact two-in-one dehumidifier and air purifier designed for small to medium-sized rooms.

In terms of air purification, though, it boasts an H13 HEPA filter, capable of trapping up to 99.95 per cent of microscopic particles, including dust, pollen, pet dander, smoke, and other airborne allergens as small as 0.3 microns.
This makes it a solid choice if you struggle with hay fever, asthma, or other respiratory sensitivities. The night mode is handy for light sleepers, too. At just 35db, it runs at a gentle hum – ideal for uninterrupted sleep or study sessions. You can increase the fan speed during the day to tackle stuffy air, then tone it down at night for peace and quiet.

- Multi-layered filtration system for allergens, smoke, VOCs and more
- Quiet enough for bedrooms and offices
- Easy to set up and use
Take note
- No wifi or app control
- No smart air quality sensor
A strong performer for purifying large rooms, this appliance has a sophisticated five-stage filtration system and an H11 HEPA filter that traps everything from dust and pollen to smoke and pet dander. It’s a great choice if you want something reliable and effective without paying for extra features you might not use, such as voice or app control.
It features three fan speeds, a sleep mode, and a filter change indicator. While some buyers might appreciate this simplicity, others might find the lack of innovative features more frustrating than freeing. For example, there’s no air quality sensor, meaning it won’t detect pollution spikes or automatically ramp up its settings to deal with them. You’ll have to adjust it manually, which means the onus is on you to sense when to dial up air purification and vice versa – often a tricky job.
It’s functional and minimalist in design, but a little on the bulky side. That said, it's a solid, affordable option if you’re looking for powerful, reliable filtration and don’t mind the basic controls or lack of smarts.

Why we love it
- Has a USB port for connecting to laptops
- Purifies automatically once plugged in
This small, sleek purifier is so whisper-quiet on its lowest setting that I had to check if it was even switched on. Suitable for rooms up to 7 sq m, it has a USB connection rather than a plug, so it would be handy next to a computer or even in a car. It’s extremely simple to set up, and it enters automatic mode as soon as it’s plugged in, adjusting fan speed automatically to suit the air quality. This can also be adjusted manually.
The filtering process includes four-stage air disinfection, with a silver ion coating to destroy microorganisms and activated carbon to tackle smells and gases. Depending on usage, it’s the filter lasts about every three to six months. I loved how portable and light it was, at just 400g. If you want to improve the air even when you’re driving, I still think it’s a good bet.

Your questions about air purifiers answered
What is the best air purifier?
My tests found that the Levoit core 400s is the best air purifier you can buy. It’s packed with features, and it’s so sensitive to air quality that it even detects when a dog enters a room.
However, you get what you pay for, so anyone on a budget should opt for the Coway airmega 50, which is tidy and inexpensive but effective in most rooms. If you want something that also works as a fan, take a look at the Dyson purifier humidify + cool formaldehyde.
What does an air purifier do?
Professor David Fairen-Jimenez, head of the absorption and advanced materials lab at the University of Cambridge, says: “We spend so much time indoors that the quality of the air will impact the quality of health and life.” Air purifiers filter out various particles and pollutants to improve air quality.
The contaminants could be anything from volatile organic compounds (VOCs) generated from doing work around the house (if, for example, you have freshly painted walls) to car fumes coming in through your windows when you air your home, or the fumes that result from frying food.
How do air purifiers work?
Most work by drawing the air into the machine and running that air through a filter (sometimes several filters) to grab small particles of pollen, pollution, dust and – depending on the type of filter – viruses and smaller particles. It then sends the clean air out into the room again. Some also use something called ultraviolet germicidal irradiation to ‘kill’ any viruses caught in the air.
It’s worth noting it isn’t only catching small particles that’s tricky, but also PM 2.5, or fine particulate air pollution, which is another area researchers are continually looking into.
Do air purifiers remove dust?
In a word: yes. The thing to know about air purifiers is that their efficacy depends largely on the filtration system and the size of the particles they can capture. The gold standard in filters is the high-efficiency particulate air filter (aka the HEPA filter), which captures at least 99.97 per cent of 0.3-micron and larger particles. The naked eye can’t see particles smaller than 10 microns in size, so, yes, most air purifiers will remove dust from the air.
Do air purifiers help with allergies?
If your allergies are triggered by pollution or other fine particles in the air, a good purifier is likely to help.
Studies carried out by Lung India show that asthma patients who were sensitised to dog and cat fur, dust mites, and birch and tree pollen found symptoms improved after 10 weeks of sleeping in a room where there was a purifier containing a HEPA filter.
That said, even the best one has limitations – you will still be breathing in allergens when you leave your home and open windows – but, on the whole, if you notice your house being clean and ventilating well reduces allergies, it’s safe to assume an air purifier will also have a positive effect.
Can air purifiers help remove smells?
A good air purifier can help reduce or even eliminate unpleasant smells entirely, while making the air you breathe healthier and fresher.
Do air purifiers help with mould?
While air purifiers won’t help treat active mould in your home, they can help capture spores from the air, preventing them from reproducing and spreading throughout your home, so these gadgets are a great way to control the spread of airborne mould particles.
Should you buy a combined air purifier and dehumidifier?
Air purifiers and dehumidifiers offer the perfect combo. They both work at pulling things out of the air to make it fresher for you. Air purifiers use a filter to pull allergens and dust out of the air, while dehumidifiers pull moisture out of the air, which can cause mould growth. They’re both great appliances on their own, but together, they’re even better.
What is the Clean Air Delivery Rate?
The CADR (Clean Air Delivery Rate) indicates how quickly the purifier removes contaminants from the air, but it shouldn’t be the sole factor in deciding which one to choose. It’s advised to aim for a CADR that is at least two-thirds of your room size in square metres. For example, if your room is 20 sq m, opt for an air purifier with a CADR of at least 240 cubic metres per hour.
