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, offer dimmable displays so you don't have to contend with bright lights overnight, and still deliver enough cleaning performance to continuously remove dust, pollen, smoke, and pet dander while you sleep. You'll also want to look for a purifier with a HEPA filter and a clean air delivery rate (CADR) that matches the size of your bedroom. As a rule of thumb, a low-noise CADR of 100 to 150 CFM covers most average-sized bedrooms between 150 and 250 ft². If you have a larger primary bedroom, aim for something that delivers 200 to 250 CFM without having to crank the fan speed to its noisiest setting.
Note that we've also updated our testing methodology to evaluate air purification performance at a fan speed that minimizes operating noise; if you're interested in learning more, you can read our test bench changelog.
We've tested over 30 air purifiers, and below are our recommendations for the best bedroom air purifiers. If you'd like to see a broader overview of the product landscape, check out our recommendations for the best air purifiers and the best air purifiers for pets. 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. If you're also looking for a way to keep your floors clean with a vacuum that offers HEPA-level filtration, check out our recommendations for the best HEPA vacuums.
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 Air Purifier For Bedrooms
Bedroom8.2Particle Filtration Rate8.6Noise @ Lowest Fan Speed32.3dBANoise @ Highest Fan Speed63.2dBANoise8.0Recommended Room Size26.5 m² (286 ft²)Measured PM1.0 CADR311 m³/hr (183 CFM)See all our test resultsDisplay On/OffYesThe NuWave OxyPure is the best air purifier for bedrooms we've tested, combining quiet operation, strong CADR for large bedrooms, and a user-serviceable filtration system that helps keep long-term maintenance costs down. This premium model runs remarkably quietly at lower fan speeds while still maintaining strong air-cleaning performance. At its lowest setting, it operates at just 32.3 dBA, quiet enough to fade into the background alongside ambient noise from a fan, TV, or outdoor traffic. While its bulky footprint can make it harder to fit into smaller bedrooms, it can comfortably handle spaces up to 286 ft² (26.5 m²) at quieter settings, which covers most standard bedrooms. The display can also be turned off entirely, so you won't have to deal with bright lights glowing across your room while trying to sleep.
Its reusable filter system is another big advantage for everyday use. Most filters can be washed rather than replaced, helping keep long-term maintenance costs down. The system also includes a combined HEPA and activated carbon filter to help trap airborne particles, such as dust and pollen, while reducing odors. Built-in air quality sensors and automatic operating modes work together to adjust fan speed in real time based on what's in the air, so you can set it and forget it before bed. If you do want more hands-on control, though, Wi-Fi connectivity lets you monitor and manage it remotely through the NuWave Connect smartphone app, so you never have to leave the comfort of your covers to adjust a setting.

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. Its smaller footprint makes it much easier to fit into tighter bedroom layouts than bulkier premium purifiers, and it's compact enough to place on a larger nightstand or dresser without taking up space 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. It's a good match for medium-sized rooms, with enough coverage for all but the largest bedrooms, and it handles spaces up to 197 ft² (18.3 m²).
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, though it does get noticeably louder at its highest fan speed, more like a small cordless vacuum running nearby. 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
Bedroom8.3Particle 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/OffYesFor most people shopping for a bedroom air purifier, the Levoit Vital 200S hits the sweet spot; it offers the right balance of performance, price, and overnight usability for standard-sized rooms without the bulk or cost of a premium unit. It runs more quietly than the pricier Mila Air 3 at both its lowest and highest fan speed settings, operating at just 32.7 dBA on its quietest setting, which is soft enough to blend into the background of a bedroom alongside a fan or distant outdoor noise. Even at its maximum fan speed, it tops out at 55.6 dBA, making it noticeably quieter than many competing purifiers running at full power. 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 the Mila air purifier, 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 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 Levoit Vital 200S 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.

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.

Coway Airmega AP-1512HH Mighty:
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.
