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.

Best Air Purifier For Bedrooms
Bedroom8.2Particle Filtration Rate8.6Particle Concentration7.9Noise @ Lowest Fan Speed32.3dBANoise @ Highest Fan Speed63.2dBASee all our test resultsAir Cleaning Rate405 m³/HourThe 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/BP03 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 Mid-Range Air Purifier For Bedrooms
Bedroom8.4Particle Filtration Rate8.0Particle Concentration9.6Noise @ Lowest Fan Speed32.7dBANoise @ Highest Fan Speed55.6dBASee all our test resultsAir Cleaning Rate268 m³/HourLook at the Levoit Vital 200S for a less expensive air purifier. It runs almost as quietly as the NuWave OxyPure at its lowest fan speed, making it just as discreet when used later at night. 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. Another minor downside is that it has a slightly simpler filtration system compared to the NuWave OxyPure, with no extra 'BioGuard' or ozone filters. Its main filter isn't HEPA-rated, though this unit is just as capable as HEPA alternatives in trapping fine airborne allergens.
Still, if you want a device with a HEPA-rated filter, the Winix 5500-2 is a stellar alternative that also delivers excellent overall particle filtration. It operates just as quietly and is similar in dimensions. However, unlike the Levoit, the Winix 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
Bedroom7.9Particle Filtration Rate7.1Particle Concentration8.7Noise @ Lowest Fan Speed33.0dBANoise @ Highest Fan Speed55.1dBASee all our test resultsAir Cleaning Rate162 m³/HourIf you want to spend less on an air purifier for use in bedrooms and don't mind sacrificing some smart features, the Levoit Core 300 is a great option. Unlike the Levoit Vital 200S, it has no Wi-Fi connectivity and no built-in particle sensors; in real-world terms, that means you can't operate the device remotely using your smartphone, and it's incapable of automatically adapting to air quality changes in real-time.
That said, this simpler air purifier has got it where it counts. It has a smaller overall footprint than the Vital 200S, making it easier to fit in smaller rooms or on a nightstand or shelf. It also delivers good overall air purification performance, though admittedly not when the device is running at its lowest possible fan speed. CADR is lower than either the Vital 200S or NuWave, so it isn't the best fit for big bedrooms.

Best Air Purifier For Small Bedrooms
Bedroom7.4Particle Filtration Rate6.7Particle Concentration7.9Noise @ Lowest Fan Speed33.6dBANoise @ Highest Fan Speed54.7dBASee all our test resultsAir Cleaning Rate99 m³/HourThe 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.
Notable Mentions
- Coway Airmega AP-1512HH Mighty: The Coway Airmega AP-1512HH Mighty is a mid-range air purifier with a built-in ionizer, which you can turn on and off, and a built-in particle sensor that allows for automatic fan speed adjustment, depending 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. See our review

Levoit Core 400S:
The Levoit Core 400S is a good alternative to the Levoit Vital 200S, which performs similarly but has a cylindrical form factor. It makes a little more noise in its lowest fan speed setting.
