If you live in an area where air quality is a concern, it might be worth buying an air purifier capable of running all day and all night. Now, there are a few concerns you need to take into account when purchasing an air purifier for this kind of use. Quiet operation is a must, as is the ability to dim the lights on the device's user interface, so you won't have to contend with bright blinking lights when trying to get some shuteye. There are quite a few options on the market to fulfill these simple requirements, but there are major differences in overall system performance and feature sets.
We've tested over 25 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 have a bigger bedroom, you could also consult our recommendations for the best large-room air purifiers. On the other hand, if you're looking for a way to keep your floors clean but would like a vacuum that provides HEPA-level filtration, you can check out our recommendations for the best HEPA vacuums and the best vacuums for allergies.
We've independently tested over 25 air purifiers, purchasing each one ourselves like the average consumer would: no cherry-picked samples or talking points from manufacturers. 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
BedroomParticle Filtration RateNoise @ Lowest Fan SpeeddBASee all our test resultsNoise @ Highest Fan SpeeddBAThe best air purifier for bedrooms we've tested is the NuWave OxyPure. This premium model is remarkably quiet at lower fan speeds, making it an ideal fit for overnight use. While its bulky footprint makes it hard to fit into smaller bedrooms, there's no contesting that it performs remarkably well, providing a high clean air delivery rate and superb particle filtration. Instead of conventional replaceable filters, most of the NuWave model's filters are washable and reusable. This system comprises a stainless steel mesh pre-filter, two ‘Bio-Guard’ filters for viruses and bacteria, an ozone filter, and a combined HEPA/pellet-type activated carbon filter. Except for the HEPA/activated carbon filter, which you need to replace every year, the manufacturer advertises these parts to have a 20-year lifespan, requiring only periodic washing.
It features a bevy of particle sensors and a few fully automatic operating modes, allowing it to adjust its fan speed in real-time based on current ambient particle counts, so there's no need to wake up and make any adjustments if air quality takes a dive while you're sleeping. It's also Wi-Fi enabled, so you can operate it remotely using the NuWave Connect companion app. If you're looking for another high-end air purifier, the Dyson Purifier Big+Quiet Formaldehyde BP04 is a solid option that's even quieter at its highest fan speed compared to the NuWave. That said, its overall air purification performance is inferior.

Best Upper Mid-Range Air Purifier For Bedrooms
BedroomParticle Filtration RateNoise @ Lowest Fan SpeeddBASee all our test resultsNoise @ Highest Fan SpeeddBAIf you're looking for something a little more compact and a little less expensive for use in a bedroom, the Mila Air 3 is a good option. This premium model is available with a number of user-selectable filter options, intended for a variety of different types of environments and needs. Our test unit is equipped with what Mila dubs 'The Big Sneeze' filter, which is meant to strike a balance between filtration and permitting sufficient airflow for medium-sized rooms, like bedrooms. It boasts H13 HEPA filtration, but lacks a carbon layer for trapping odors. If your bedroom is next to a busy shopping street and you require something with the latter, we'd recommend buying a different kind of filter.
In terms of actual performance, the Mila is a good match for medium-sized rooms, with sufficient CADR for all but the largest of bedrooms. While it can get a little loud at its highest fan speed, it's far from obtrusive in lower settings, and you can run it overnight without it being too much of a nuisance. Beyond that, it's relatively small for a unit with this level of capacity, and it can be set up on a larger dresser or nightstand. It also has a built-in carbon monoxide and particle sensors, allowing it to change its fan speed setting automatically, handy if air quality takes a dive overnight.

Best Mid-Range Air Purifier For Bedrooms
BedroomParticle Filtration RateNoise @ Lowest Fan SpeeddBASee all our test resultsNoise @ Highest Fan SpeeddBALook at the Levoit Vital 200S for a less expensive air purifier. It runs more quietly than the pricier Mila Air 3 at both its lowest and highest fan speed settings, making it a great option if you're a particularly light sleeper. It also features a built-in light sensor, which turns off the display when you enter a dark room; that said, there's no quick way to activate this function. You can only enable it through the Levoit VeSync companion app. The app also lets you monitor air quality in real-time. In terms of performance, its max CADR falls slightly short of the smaller Mila, though it's still a good fit for all but the largest of bedrooms. Its main filter lacks HEPA certification, but it does perform similarly to devices with filters that do meet this standard.
Still, if you want a device with a HEPA-rated filter, the Coway 200M is a stellar alternative that provides higher CADR. However, it does run louder. However, unlike the Levoit, the Coway has a built-in ionizer. This system imparts a negative charge to smaller airborne particles, causing them to stick together and fall out of the air, where you can then dust or vacuum them away. Unfortunately, these systems also produce ozone as an operating byproduct, which can irritate your respiratory system. Thankfully, you can easily turn off the ionizer with no significant impact on particle filtration performance.

Best Budget Air Purifier
BedroomParticle Filtration RateNoise @ Lowest Fan SpeeddBASee all our test resultsNoise @ Highest Fan SpeeddBAThe Levoit Core 200S is the best air purifier for a small room we've tested. This device is even more compact than the Levoit Core 300, allowing you to fit it even more easily in areas where space is at a premium. However, it lags behind its bigger sibling in raw performance. It does a worse job of trapping the smallest airborne particles, and its clean air delivery rate is even lower, so it'll struggle to efficiently clear particles in larger rooms. It also runs slightly louder than those aforementioned alternatives at its lowest fan speed. Even then, however, its operating noise is only as loud as light rain falling against your window, so it isn't likely to keep you up at night.
Unlike the Core 300, the Core 200S is Wi-Fi enabled, which allows you to change device settings, set operating schedules, and send filter replacement or cleaning notifications through the VeSync companion app. However, there's no particle sensor, so the device can't automatically adapt to real-time changes in ambient particle levels. You also can't monitor air quality yourself.

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 does fall a little short of the Levoit Vital 200S in particle filtration performance and makes a little more noise.

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.
