If air quality is a concern in your bedroom, a dedicated air purifier that runs all day and all night is worth considering. The best bedroom air purifiers operate quietly enough not to disturb your sleep while still delivering enough cleaning performance to continuously remove dust, pollen, smoke, and pet dander while you sleep.
We've tested more than 50 air purifiers, and below are our recommendations for the best air purifiers for bedrooms based on our test results. Here are the most important things to look for:
- Features: Many air purifiers have dedicated sleep modes that reduce their fan speed to the lowest possible setting to minimize noise. That being said, not all Sleep Modes are built alike: look for a unit that has an auto-off display to minimize distractions in a dark room.
- Clean Air Delivery Rate (CADR): As a rule of thumb, a CADR of 100 to 150 CFM covers everything from average-sized bedrooms to large primary suites, ranging in size between 150 and 250 ft².
- Operating Noise: When looking at our reviews, consider a unit that produces under 34 dBA in its lowest fan speed setting.
- Footprint: Bedrooms tend to be smaller than most other rooms in your apartment or home; units with a high performance-to-size ratio are ideal for this sort of usage.
If you want a more detailed breakdown of what to look out for, check out the buyer's guide at the bottom of the article. If low operating noise is your absolute top priority, with other considerations like performance and footprint taking a backseat, see our recommendations for the best quiet air purifiers. See our recommendations for the best air conditioners for bedrooms if you're trying to keep things cool; we've also recently updated our testing methodology to provide more accurate, relevant performance data.
We buy and independently test air purifiers with no manufacturer samples, sponsorships, or pre-approved talking points. Each unit goes through the same standardized test bench, and the results are validated by multiple teams before being published on our website, so you can accurately compare them side by side.

Best Bedroom Air Purifier For Most People
Bedroom8.4Particle Filtration Rate8.1Noise @ Lowest Fan Speed32.4dBANoise @ Highest Fan Speed60.7dBANoise8.5Recommended Room Size17.7 m² (190 ft²)Measured PM1.0 CADR207 m³/hr (122 CFM)See all our test resultsDisplay On/OffDimmable onlyThe best bedroom air purifier for most people that we've tested is the Winix 5530. It offers the right balance of performance, price, and overnight usability for standard-sized bedrooms without the bulk or cost of a premium unit. It runs very quietly overall, being practically inaudible at its lowest fan speed setting. In that configuration, its operating noise is soft enough to blend into the background of a bedroom alongside a fan or distant outdoor noise, making it an ideal option for overnight use. That said, it's noticeably louder than some alternatives at its highest fan speed setting, which can be disruptive if the unit automatically increases its fan speed overnight due to a drop in air quality. It also features a built-in light sensor that automatically dims the display and slows its fan speed in a dark room. On-board Wi-Fi allows you to monitor air quality in real time and adjust settings remotely without getting out of bed.
The main trade-off is that its CADR falls slightly short of higher-end models, so it isn't quite as well-suited for the largest bedrooms that need especially fast air cleaning, though it's still far from a poor performer in this regard. At quieter settings below 45 dBA, it can maintain a high enough CADR for all but the most massive of primary suites. While its main filter isn't officially HEPA-certified, it still performs similarly to many purifiers with HEPA-rated filters when it comes to reducing common bedroom particles like dust, pollen, and pet dander.

Best High-End Air Purifier For Bedrooms

Even at low, quiet fan speeds, where its operating noise is barely audible, its clean air delivery rate (CADR) is more than sufficient to handle common allergens like dust, dander, or pollen, even in the largest primary bedrooms, and it totally eclipses that of the cheaper Winix 5530. Its laser particle sensor also maintains a fairly accurate picture of current air quality, and allows it to automatically adjust its fan speed if particle levels increase overnight. Its integrated display can also be turned off overnight to minimize distractions, and you can set operating schedules or change settings from the comfort of your bed using its smartphone companion app. Beyond that, while it's a little on the bulky side, its flat top effectively makes it double as functional furniture rather than an eyesore you keep well out of the way.
If there's one potential dealbreaker with this unit, it's the additional electrostatically-charged layer in its filtration system, which produces ozone while the unit runs. For the record, its ozone production level is certified to fall within safe limits, but the main issue is that this system can't be turned off. This can be a dealbreaker for those with acute ozone sensitivity or for some pet owners.

Best Upper Mid-Range Air Purifier For Bedrooms
Bedroom7.8Particle Filtration Rate8.8Noise @ Lowest Fan Speed33.7dBANoise @ Highest Fan Speed61.2dBANoise7.2Recommended Room Size23.5 m² (253 ft²)Measured PM1.0 CADR275 m³/hr (162 CFM)See all our test resultsDisplay On/OffYesConsider the Levoit Core 600S if you don't want to spend as much on a bedroom air purifier as the Blueair Blue Signature Large, and find the latter's always-on ionizer to be a dealbreaker. It lags behind the class-leading Blueair in terms of CADR, but the Levoit is still far from a bad performer in this regard, with enough performance to clear the air in above-average bedrooms at low, quiet fan speeds. Unfortunately, it's much louder at its highest fan speed, and it could wake you up if air quality dips overnight and the Levoit's onboard particle sensor causes it to increase its fan speed. It does have a slightly narrower footprint than the Blueair, though it can't serve as functional furniture and won't blend into your home's decor as seamlessly.
The Levoit is Wi-Fi-enabled, allowing you to pair the device with your smartphone and view an air quality estimate, adjust the fan speed, or see filter change alerts through its companion app, so you don't have to roll out of bed to make a settings adjustment. If you'd rather not use your phone, the 600S also features Google Assistant and Amazon Alexa integration for making voice commands.

Best Budget Air Purifier For Bedrooms
Bedroom8.1Particle Filtration Rate6.5Noise @ Lowest Fan Speed31.2dBANoise @ Highest Fan Speed56.0dBANoise9.0Recommended Room Size9.0 m² (97 ft²)Measured PM1.0 CADR106 m³/hr (62 CFM)See all our test resultsDisplay On/OffDimmable onlySmall, affordable, and quiet enough to fade into the background, the Dreo Air Purifier 338S is a great fit for small bedrooms or anyone looking to outfit multiple rooms without spending a lot. Its compact size and low price also make it a practical alternative to a single larger purifier in open-concept spaces like studios or lofts, where spreading a few smaller units around the room can be just as effective. The main trade-off is raw air-cleaning performance. It does a worse job of trapping the smallest airborne particles than pricier alternatives. Its lower CADR also means it'll struggle to clean larger bedrooms efficiently. Even at higher volumes, it's best suited for medium-sized bedrooms and might struggle a little in especially large primary suites. That said, at its lowest fan speed, it's almost inaudible yet still offers just enough coverage for small bedrooms.
Compared to bulkier models like the Winix 5530, this model is much easier to fit on a nightstand, dresser, or desk without taking up too much space. There's no full display off function, but you can dim its display so you won't have to deal with bright indicator lights while trying to sleep. Wi-Fi connectivity also lets you adjust settings, create schedules, and receive filter reminders through a smartphone companion app without getting out of bed. It also has an air quality sensor that enables it to adjust its fan speed if particle levels rise overnight.

Mila Air 3:
The Mila Air 3 is an high-end air purifier that's more compact than the Blueair Blue Signature Large and features a unique swappable filter ecosystem, with different filters intended for different environments, but it has a much lower maximum CADR.
See our review -
Coway Airmega Mighty AP-1512HH:
The Coway Airmega AP-1512HH Mighty is a mid-range air purifier with a built-in ionizer that you can turn on and off, and a built-in particle sensor that automatically adjusts fan speed based on current air quality. That said, it falls a little short of the Winix 5530 in particle filtration performance and makes a bit more noise.
See our review -
Levoit Vital 200S:
The Levoit Vital 200S is a good alternative to the Winix 5530, with lower operating noise when both units are set to their maximum fan speeds. That said, it performs noticeably worse than the latter at quieter settings, making it a little worse at continuous low-noise operation.

Levoit Core 200S:
The Levoit Core 200S is a compact, budget-friendly air purifier that's just as small as the Dreo Air Purifier 338S. That said, it's CADR at both its maximum and low-noise fan speeds lag behind the latter.

What To Consider When Buying An Air Purifier For Bedroom Use
Clean Air Delivery Rate (CADR) And Coverage
Generally speaking, when considering an air purifier for bedroom use, it's best to measure the size of your own bedroom, so you don't overpay for a unit with far more performance than needed, or, worse, end up with too little performance for your needs. If you're looking at our reviews to help make that choice, pay close attention to the 'Low-Noise Particle Filtration Rate' test, particularly the 'Recommended Room Size' field.
- 70 - 100 ft2 (6.5 - 9.3 m²): Very small secondary bedrooms in basements, or especially small apartment bedrooms
- 120 - 150 ft2 (11.1 - 13.9 m²): A size range that covers the vast majority of bedroom sizes in most apartments and homes
- 180 ft2 or more: Very large primary suites.
While it might be tempting to only consider maximum CADR, that isn't as relevant a metric for an appliance that you plan on leaving to run overnight. A unit with high max CADR might be able to bring air quality up to a good level in a short span of time, but can be highly disruptive at these higher fan speeds, which obviously won't do if you're trying to get some sleep and expect poor air quality to persist overnight.
Operating nOise
If you're using an air purifier overnight, it's best to leave it at a lower fan speed setting to minimize noise. In that configuration, most air purifiers tend to be pretty quiet, though there's still some variance there.
- 30-32 dBA: Practically inaudible, and unlikely to be a distraction even for the lightest of sleepers.
- 32.5-34 dBA: Still very quiet, but can be heard if you have particularly sensitive hearing.
- 35 dBA or more: Similar to a fridge running nearby, or soft rainfall against a window. Can be distracting for very light sleepers.
Features
There are a few features that are especially nice to have if you're shopping for a bedroom air purifier:
-
Air Quality Sensor Auto Mode
- This allows the air purifier to automatically adjust its fan speed setting in real time, without forcing you to fiddle with its onboard controls or a remote control, which is handy if air quality in your bedroom takes a dive while you're asleep.
-
Remote Control/App
- An included remote control or a smartphone companion app also allows you to operate the unit without having to get out from under your covers.
- Display Off Functionality
- This minimizes distractions in a dark bedroom by keeping you from having to contend with any bright indicator lights reflecting off your wall, or simply being visible out the corner of your eye.
