Tried & tested: The best air purifiers in 2025 for the bedroom and nursery

We chose this as our best air cleaner overall as it's the most awarded air purifier brand in the UK (based on the awards received for performance between 2019-2023 conducted by 16 independent consumer associations, certifications, testing facilities and media houses) and it's designed to filter the air in spaces up to 48m². We love the modern and minimalist design that'll look good in any home, as well as being user-friendly with a 5-colour indicator and simple 2-button design, with an affordable price.

We like that when you connect to the Blueair app you can monitor your air quality, set schedules, use geofencing technology and more. You can even control your air purifier with voice assistance. It's a great performer too, filtering out 99.97% of airborne particles down to 0.1 microns in size – if that means nothing to you, just know that it's best than most air purifiers, which only promise to filter down to 0.3 microns. It also works up to 83% faster with 50% less noise than previous Blue models, making it perfect for use at night in the kids' bedroom with its child lock.

One customer thought the product was very good, commenting on the "surprisingly low noise" and confirming they found it to be very efficient. "Looks visually stunning too", they said, "The app works excellent and is very useful. I love the automatic fan speed mode and the air quality monitoring." They did mention being worried about finding replacement filters though, so this may be the only challenge.

Instant is all about making life at home easier, and we're on board with that! Whether you're looking for an air purifier for a small or large room, this brand has you covered with air purifiers suited to various room sizes.

The Instant Air Purifier AP300 is a larger model that has a three-in-one filter system that claims to remove 99.9 per cent of bacteria, viruses and mould in rooms up to 36m². It has an auto mode that senses the air quality and adjusts the fan speed accordingly. The best thing about this air purifier? It's designed to operate quietly, and it really works according to our Deputy Commercial Content Editor, Lily Anderson, who tried and tested it in her own home.

"My partner has recently discovered he has asthma, and we were looking for something for our home that would reduce dust, dander and pollen," Lily said. "We opted for the larger option as we have a combined living room and dining room; this device works well in our high traffic rooms. We love how you can monitor the air quality via the screen and that this air purifier is equipped with sensors that can monitor the air quality 24/7. The night mode and eco mode are a big plus for us as well."

Other reviewers have been similarly impressed by the function of this air purifier, but unimpressed by the availability of replacement filters which, they say, are very difficult to get hold of. The size of the unit is also larger than others, but it's one of the more affordable options in our round-up.

This compact and affordable air purifier is small in size and appropriate for rooms of up to 40m². The TotalClean 4-in-1 Tower Air Purifier alters the air once per hour at high speed so your room feels fresh and purified. The appliance is quiet, so it can be in operation without disruption making it one of the best air purifiers for baby in the nursery. Plus, the built-in aromatherapy feature means you can even add essential oils that fill the air with your favourite scent as it cleans.

The HoMedics TotalClean 4-in-1 Air Purifier was tried and tested by Commercial Content Writer Ellen Kinsey: "If you are looking for an air purifier under £100 that purifies a small room such as an office or bedroom, then this is a great choice. Living in an urban area means a lot of pollutants get trapped in the air in my flat so having this air purifier is really handy in ensuring the environment is fresh and clean. I especially love the aromatherapy feature, which allows me to have a beautifully scented room while it clears the air."

It has a night mode as well as filter replacement indicator and is remote controlled. There are fancier, more high-tech options on the market but for a great price this piece of equipment gets great reviews.

Delivering a super-fast air purification with 20m² covered in less than eight minutes, the Philips Series 3000i is truly a first-class machine. The device filters 99.97 per cent of airborne allergens, pollen, fine dust, particles and bacteria and is extremely easy to use with either the display or managed with the Philips Clean Home+ app.

"I bought this as I was getting a dry throat and was wondering about air quality," said one happy reviewer. "Amazing how responsive it is, and the app works really well." The main complaint with this air purifier is that it consistently has problems connecting with its app. However, there is a touch pad on top for direct control. It's larger than some other purifiers but it's also for a larger room - up to 104m² - and has a 360-degree airflow.

You can place the device in sleep mode at night, the display lights will be dimmed and the purifier will operate in near silence - as low as 34db. At faster speeds reviewers report it can be a little noisier.

If you are looking for good value for money and great reviews, LEVOIT makes excellent air purifiers at a mid-range price. The Core 400S has many of the useful features that its competitors have on offer such as an auto mode that detects air quality in real-time and a display to check the air quality of your home. It claims to have a reach of 83m² twice per hour - a huge space - thanks to its Vortexair technology. The device eliminates 99.9 per cent of particles, and can be operated via an app or via voice control with Alexa.

"I wouldn't be without it now," said one happy reviewer. "It makes the air like being on top of a mountain. It is so quiet it blends into the background and reacts to the slightest change in air quality. (Like when you open the oven door while cooking) so I would buy these again in a heartbeat. I also have the smaller version, which we have in the bedroom and use all night. No more tired eyes or sore throats and greatly assists my wife's breathing disorder."

Complaints include the high expense of replacement filters and dissatisfaction over the removal of unpleasant smells such as cigarette smoke and cooking fumes.

If you're looking for a nifty little machine that's perfect for moving from room to room we think you'll like the Coway airmega 100, chosen as best for portability and one of the best hepa air purifier options in our list. In comparison to the airmega mighty, this tiny cylinder is easy to tuck away, taking up any space at all, running quietly in the corner of your room. You can choose from three fan settings, with the lowest being hardly noticeable. It's also budget-friendly if you're not looking to invest in a bigger machine yet.

This machine may be small, but it does the job well! It features a pre-filter, deodorization filter and a HEPA filter that Coway says removes 99.999 per cent particles down to 0.01 microns in size, including pollen, dust and other allergens, as well as 99 per cent of volatile organic compounds and odour. That's pretty impressive for such a little guy – and the filters last up to a year, rather than six to nine months with other models.

We also like that the top lights up for a calming effect, and this doubles as an indicator to let you know more about the art quality in the room, with different colours indicating whether it's good or not. One customer wasn't sure about the sensor's accuracy though, saying; "I got the Coway Airmega 100 for my daughter, who has eczema, to reduce pet dander and dust mites. It’s quiet, effective, and seems to help with her symptoms, which makes it worth the purchase. However, the air quality sensor showed "good" air quality immediately after turning it on, which felt off since we have a dog and had never addressed air quality before. While it seems to work well overall, the sensor's accuracy could be better."

If you're looking for something more unusual and stylish for your living space, then this air purifier is a great contender! The pentagonal shape and dark grey design gives it a contemporary look, so you won't need to try and tuck this one away in a corner. One customer warns that the unit is quite big, so it's just as well the we love the design! It also has two fabric handles, which is great for portability, making it easier to move from room to room if needed, so it's a good investment, meaning you won't need to buy more than one.

We like that you don't need to monitor or do anything because the PureSense responsive technology does all the work for you, measuring air quality and automatically adjusting purification levels. With 9 speed settings you can cranks things up when you need a boost – like when your dog gets back from the park or if it's pollen season. It has an auto-sleep feature too, and it'll even let you know when the filter needs changing with its indicator.

Customers agree that the operation is nice and quiet. One reviewer said; "Seems powerful and can be silent when in Smart mode, which I like. It’s a bit bulky, hence why I removed a star, but overall it’s very easy to use. I would have loved if it had a cover on top for when not in use. I need to improvise something to protect against my toddler." Another customer found that the app didn't work well with Google home or Alexa though.

We just had to include this unusual air purifier in our round-up – we think it's the perfect choice for plant lovers or anyone who is looking for a discrete machine. What we like most about it is that the practically silent air purifier actually doubles up as a plant pot, meaning you can add in your own choice of plants – although it doesn't come with a plant. One reviewer said, "Great design, looks so good on my sideboard, looks just like a classy plant pot, and it’s quite quiet when it’s in use. I bought one of the recommended plants to go in it. It’s easy to set up, and much larger than I expected it to be, lovely size. I really like this product."

Keep in mind that this does mean you'll have to water and maintain the plant you choose, so make sure you have a green thumb. Plus, it'll add to the set-up time as you'll need to pot the plant yourself rather than just plug the air purifier in and switch it on. If you're new to houseplants, they do provide a list of recommended air-purifying plants to help you decide on the best one for your home. And because they pot is nice and big, you can go for a decent-sized mature plant, which should be easier to look after as it'll already be established with good roots.

The product works by drawing air in through the purifier and into the roots to break down and absorb pollutants from the air. It's super convenient too as there's no need to replace the filters, the ceramic photocatalytic filter can simply be washed under water now and then. As a bonus, it monitors temperature, humidity, CO2 and more, all of which you can monitor through the app.
