Best air purifiers for bedroom

by motherandbaby |
Updated on

You might think that you only have to worry about air quality outdoors where there is polution, but the quality of the air inside your home is just as important! Pollutants and pollen from outside can enter your home through windows and doors, and let's not forget about indoor pollutants like cigarette smoke, dust, and pet dander. Appliances like air purifiers and air dehumidifiers are designed to clean and improve the air quality in your home so that you don't have to worry about you or your your children inhaling toxic compounds from your cleaning materials, amongst other things.

Many peo0ple ask the question – are air purifiers worth it? And we think the answer is, yes! If your baby or toddler is showing signs of allergies or childhood asthma, it's best to keep airborne particles such as dust, pollen and mould spores to a minimum. Allergens and pollutants in our air are ever increasing, and using a high-efficiency air purifier in their room will significantly reduce the volume of irritants that they have to encounter and breathe at all hours of the night, and especially when they are sleeping – while your little ones will still be exposed to some allergens during the day, and this is beneficial to their developing immune systems, during sleeping hours it's better that your baby or child breathes clean air so that their lungs and immune system have time to rest and rejuvenate.

Not all air purifiers tick the same boxes though. They come in different shapes and sizes, have different features and ways of working, and what suits one home may not suit yours. That's why we have done the hard work for you, to find the best deals, with the top products to help make your decision easier. So whether you're look for the best air purifier for allergies or specifically, the best air purifier for pets, you'll find something in our roundup below. We've chosen a variety of products, including the best air purifier for bedroom use and the best budget air purifier.

Best air purifiers for your home in 2025:

Here's our round-up of the top ranked air purifiers according to our research and what customers are saying about the products in reviews...

Best air purifier overall

Blueair Blue Max 3250i Air PurifierImage: Amazon

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.

Pros

  • Most awarded air purifier brand in the UK (2019-2023)
  • Modern, minimalist design looks good in your home
  • Easy to use with a 5-colour indicator and simple 2-button design
  • More effective than other brands
  • Faster than previous models makes it more effiecient
  • Quieter than previous models - good for bedroom use at night
  • App provides more features - monitoring air quality, setting schedules
  • Voice assistance control

Cons

  • Challenging to find replacement filters

Best air purifier on a budget

Instant air purifierAmazon
Price: $64.90 (was £81.41)

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.

Pros

  • App controls use and shows air quality
  • It's more affordable than some other alternatives
  • There's a low energy eco-mode
  • Auto mode adjusts fan speed according to need

Cons

  • Replacement filters are difficult to get hold of
  • It's larger than some other alternatives

Best air purifier for a refreshing scent

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.

Pros

  • aromatherapy feature gives off a scent of choice
  • An affordable option compared with others
  • Night mode

Cons

  • Not as quiet as other options
  • No app - it's remote controlled

Best air purifier for large rooms

Philips Series 3000i Connected Air Purifier AC3033/30Amazon

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.

Pros

  • Very quiet at low speeds
  • Caters to a large area or room
  • Super fast air purification
  • Auto mode automatically adjusts speed according to need
  • Attractive, modern design

Cons

  • Some units have problems connecting with the app
  • At higher speeds it's noisier than some would like

Best air purifier for voice control

LEVOIT Air Purifier, The Core 400SImage: Amazon
Price: $219.99 (was 239.99)

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.

Pros

  • Manages a large area
  • Manual, app and voice control (via Alexa)
  • Auto mode that automatically adjusts speed according to need

Cons

  • Large compared with some competitors
  • Some say it doesn't deal with unpleasant smells effectively

Coway airmega 100 air purifier

Best air purifier for portability

Coway airmega 100 air purifierImage: Amazon

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."

Pros

  • Tiny size is great to move around from room to room
  • Run quietly with three fan settings to choose from
  • Budget-friendly
  • Filters lastlonger than other models
  • Top lights up as an indicator for air quality
  • Lights create a calming mood in the room

Cons

  • One customer thought the sensor's accuracy could be better

Best air purifier for style and function

AEG AX91-404GY air purifierImage: ao.com
Price: $529

ao.com

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.

Pros

  • Contemporary design looks good in your home
  • Two fabric handles make it easy to move between rooms
  • Continually measures air quality and automatically adjusts purification
  • Indicator lets you know when filter needs changing
  • Runs quietly and has 9 speed settings when you need a boost

Cons

  • Quite large
  • Customer said it doesn't work well with Google Home or Alexa

Vitesy natede smart air purifier

Best air purifier for plant lovers

Vitesy natede smart air purifierImage: Amazon

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.

Pros

  • Unusual aesthetic design - an air purifier than doubles as a plant pot
  • Add your own choice of plant to suit your preferences and decor
  • Comes with a list of recommended air-purifying plants
  • Water-washable ceramic filter means you won't have to replace it
  • Monitors temperature, humidit, CO2 and more via app

Cons

  • Setup is longer as you have to pot up your own plant
  • Doesn't come with a plant
  • You'll have to maintain the plant you choose

What to consider when buying an air purifier

There are a few aspects to consider when looking to invest in an air purifier, such as speed, noise, built-in sensors and the type of filters.

Speed: Most air purifiers have multiple speed settings, so consider picking one that you can adjust. For example, if you’re in a meeting, you can turn it down, or you can turn it up when the pollen levels are high.

Noise: Where you are keeping your air purifier will depend on the noise level to look for when choosing this appliance. Consider one that works quietly if it is for your bedroom or perhaps one that has a sleep mode so that the light and noise from the device will be kept at a minimum.

A built-in sensor: A built-in air sensor will sense when the air quality is poor and automatically switch itself on - making your life easier. This is a great function for those who suffer seasonal allergies.

HEPA filter: There are various filters when it comes to air purifiers, but HEPA is the best. HEPA, which stands for high-efficiency particulate air, catches more pollutants than other filtration systems. Nearly all of the appliances on this list feature a HEPA filter.

This may mean that your running costs work out less over the long term. More expensive ones may also be more pleasant to use because of their visual aesthetic or the fact that hat they're more quiet. this is all individual though, and you can get more budget options that stand up well next to their more expensive competitors. The best thing you can do is read reviews and comparison articles like this one in order to make an informed decision.

If you've ever wondered – do air purifiers help with dust? The answer is, they sure do! Air purifiers work effectively to remove dust from the air, particularly when equipped with a HEPA (High Efficiency Particulate Air) filter, which is designed to capture even very small dust particles with high efficiency. SO if you're worried about reducing airbonre dust particles in your home, an air purifier can certainly help to give you peace of mind.

They say that experts recommend you look for an air cleaner with a HEPA (high-efficiency particulate air) filter for a single room.

Do air purifiers use a lot of electricity?

Good news - generally speaking, no, air purifiers do not use a lot of electricity. To give you a better idea – the average air purifier uses around 50 watts, which is similar to the power of a laptop or ceiling fan. This will depend on the model and how it's set.

Where should you not put an air purifier?

To make sure your air purifier can do its job effectively you should position it so that it has enough space around the machine for air to circulate. This means you should avoid tucking it awqay in tight corners or placing it behind furniture where airflow may be more restricted. As a general guide, ensure there's at least 3-5 feet of clear space around the unit to allow for unimpeded air intake and output.

An air purifier filters the air in a room by removing harmful airborne particles and gases, and then recirculating the clean air back into the room. The machines often include HEPA filters, activated carbon filters, or electrostatic filters to help with this process, and they have fans to circulate the air through the filter.  Some air purifiers may also use a vacuum to remove larger particles like pet hair.
