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 45 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.

Conversely, if you'd like to see a broader overview of the product landscape, check out our recommendations for the best air purifiers. 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. If you're furnishing a smaller bedroom or working with limited space, you may also want to see our picks for the best small air purifiers. Conversely, if you're trying to cover a large primary bedroom or open sleeping area, our recommendations for the best large-room air purifiers are worth a look.
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
Bedroom8.3Particle Filtration Rate7.7Noise @ Lowest Fan Speed32.7dBANoise @ Highest Fan Speed55.6dBANoise8.6Recommended Room Size12.6 m² (135 ft²)Measured PM1.0 CADR147 m³/hr (87 CFM)See all our test resultsDisplay On/OffYesThe best bedroom air purifier for most people that we've tested is the Levoit Vital 200S. Its 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. It also features a built-in light sensor that automatically turns off the display in a dark room, which is especially useful if you're sensitive to bright light while trying to sleep, though you need to enable this feature in the Levoit VeSync smartphone companion app. The app also lets you 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. At quieter settings below 45 dBA, it's best suited for bedrooms up to 135 ft² (12.6 m²), though it can handle spaces up to 337 ft² (31.3 m²) if you're comfortable running it at higher fan speeds and enjoy a more noticeable white noise effect while you sleep. 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 Air Purifier For Bedrooms
Bedroom9.0Particle Filtration Rate9.1Noise @ Lowest Fan Speed31.2dBANoise @ Highest Fan Speed58.2dBANoise8.9Recommended Room Size30.8 m² (332 ft²)Measured PM1.0 CADR361 m³/hr (213 CFM)See all our test resultsDisplay On/OffYesIf price is no object, the Blueair Blue Signature Large is the best air purifier for bedrooms we've tested, combining quiet operation, strong CADR for large bedrooms, and a discrete, subtle design that should blend in with the rest of your room's decor. Even at low, quiet fan speeds, where its operating noise is barely audible, its clean air delivery rate (CADR) of 361 m³/hr (213 CFM) is more than sufficient to deal with common allergens like dust, dander, or pollen even within the largest of primary bedrooms, and totally eclipses that of the cheaper Levoit Vital 200S. 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 is a little on the bulky side, its flat top effectively makes it double as a piece of functional furniture, instead of it being an eyesore that you keep well out of the way.
If there's one potential dealbreaker with this unit, it's the additional ionization layer in its HEPASilent filtration system, which produces ozone as an operating byproduct. For the record, its ozone production level is AHAM-certified to fall within safe limits, but the main issue is that this system can't be turned off. This can be a potential dealbreaker for those who suffer from acute ozone sensitivity, or some pet owners.

Best Upper Mid-Range Air Purifier For Bedrooms
Bedroom7.6Particle Filtration Rate7.9Noise @ Lowest Fan Speed33.4dBANoise @ Highest Fan Speed62.7dBANoise7.5Recommended Room Size18.3 m² (197 ft²)Measured PM1.0 CADR214 m³/hr (126 CFM)See all our test resultsDisplay On/OffDimmable onlyChoose the Mila Air 3 if you want solid air-cleaning performance for all but the largest bedrooms, without a bulky unit taking up floor space beside your bed. While it doesn't double as an end table like the Blueair Blue Signature Large, its smaller footprint makes it much easier to fit into tighter bedroom layouts, or even set it on top of a larger nightstand or dresser so it doesn't clutter the area around your bed. Our test unit is equipped with Mila's 'The Big Sneeze' filter, which uses an H13 HEPA filter to help reduce common bedroom irritants like dust, pollen, and pet dander that can build up overnight while you sleep. If the Blueair's always-on ionizer is a dealbreaker, also know that this unit doesn't have that system and relies entirely on mechanical filtration. The main sacrifice versus the Blueair is coverage and overall performance: with both units set to similarly quiet fan speeds, the Blueair is over 40% faster to bring down particle levels in an equivalently-sized room. That said, if you plan on leaving the unit running overnight, that won't be as big a sacrifice: the Mila is still more than up to the task of operating in the average-size bedroom.
When it comes to overnight use, it checks most of the right boxes. At lower settings, it runs at just 33.4 dBA, barely audible and easy to tune out. Its dimmable display keeps the room dark while you sleep, and built-in particle sensors automatically adjust fan speed if air quality worsens overnight, so you're not stuck managing settings yourself. It also includes a built-in carbon monoxide detector, a nice added touch that offers extra peace of mind while you rest. Unfortunately, this purifier is a little harder to find in stock right now, though it is still available directly through Mila's website.

Best Mid-Range Air Purifier For Bedrooms
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 onlyIf you're looking for something cheaper than the Mila Air 3 and don't mind missing out on some convenience features, the Winix 5530 is a good choice. This mid-range unit is wider and taller than the Mila Air 3, but its more upright form factor is shallower, making it easier to tuck along wall if you want to set it up on your bedroom floor. Beyond that, it lacks the Mila's interchangeable filter system, but its three-stage HEPA-grade filter system is still more than able to handle common allergens like dust, pollen, and airborne grit. At low fan speed settings, its performance is all but identical to the pricier Mila, and it's more than able to handle all but the biggest of bedrooms in this configuration. It also runs amazingly quietly, producing a little less noise than the pricier Mila at its lowest fan speed setting. That said, it is noticeably louder than the similarly-sized and similarly-priced Levoit Vital 200S 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. Its display lights can dim, but unlike the Levoit, can't be turned off entirely, which can present a slight distraction for overnight use.
Like the Blueair Blue Signature Large, it features a particle ionization system that Winix calls PlasmaWave, which neutralizes airborne pollutants. As with that pricier unit, this system's ozone production levels are certified to fall within safe limits. Unlike the Blueair, the PlasmaWave system can be turned off, which is great if you or someone else in your household is particularly sensitive to ozone. Better yet, disabling this feature doesn't result in a noticeable loss in performance.

Best Budget Air Purifier For Bedrooms
Bedroom7.2Particle Filtration Rate6.0Noise @ Lowest Fan Speed33.6dBANoise @ Highest Fan Speed54.7dBANoise7.8Recommended Room Size7.2 m² (78 ft²)Measured PM1.0 CADR85 m³/hr (50 CFM)See all our test resultsDisplay On/OffYesSmall, affordable, and quiet enough to fade into the background, the Levoit Core 200S 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. Compared to bulkier models like the Winix 5530 and even mid-sized options like the Mila Air 3, this model is much easier to fit on a nightstand, dresser, or desk without taking up too much space. At its lowest fan speed, it runs at just 33.6 dBA, only about as loud as light rain falling against your window, and its display-off mode means 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 the VeSync smartphone companion app without getting out of bed.
The main trade-off is raw air-cleaning performance. It does a worse job of trapping the smallest airborne particles than pricier alternatives, and it doesn't use a HEPA-rated filter. Its lower CADR also means it'll struggle to clean larger bedrooms efficiently. Even at louder settings, it's really best suited for small bedrooms, dorm rooms, or nurseries up to 13.2 m² (142 ft²). It also lacks a built-in air quality sensor, so it can't automatically adjust the fan speed if conditions change while you sleep, which means you may wake up to stuffier air than you'd like.
Notable Mentions

Levoit Core 600S:
The Levoit Core 600S is an upper mid-range air purifier that provides a higher CADR than the Mila Air 3, but it's both bulkier and noisier, and slightly less practical for smaller bedrooms as a result.
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 Levoit Vital 200S in particle filtration performance and makes a bit more noise.

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 is 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 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.
