The 4 Best Air Purifiers For Bedrooms - Spring 2024 Reviews

Best Air Purifiers For Bedrooms

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 20 air purifiers, and below are our recommendations for the best air purifiers for bedrooms you can buy.

  1. Best Air Purifier For Bedrooms

    The best air purifier for bedrooms we've tested is the NuWave OxyPure. This premium air purifier operates remarkably quietly at lower fan speeds, making it an ideal fit for overnight use. It might be a little overkill for smaller bedrooms, as it has a fairly bulky footprint. However, there's no contesting its excellent overall performance, with 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, though you must wash them periodically.

    It features a bevy of particle sensors and a few fully automatic operating modes, allowing it to adjust its fan speed in real-time according to the current ambient particle counts, so there's no need to wake up and make any adjustments if air quality takes an overnight dive. It's also Wi-Fi enabled, and 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.

  2. Best Mid-Range Air Purifier For Bedrooms

    Look at the Levoit Vital 200S for a less expensive air purifier. It runs almost as quietly as the NuWave at its lowest fan speed, so it's just as discrete if you leave it running later at night. It also features a built-in light sensor, which turns off the display when you bring it into a dark room; you must enable this function separately through the Levoit VeSync companion app. It has a slightly simpler filtration system than the NuWave OxyPure, with no extra 'BioGuard' or ozone filters. That said, its onboard HEPA filter is very effective in trapping the majority of airborne particles, and it has a clean air delivery rate that's high enough to render it a suitable choice for small to medium-sized rooms. It's Wi-Fi enabled, so you can control it remotely using the VeSync companion app, allowing you to monitor air quality in real-time.

    If you don't need Wi-Fi connectivity, the Winix 5500-2 is a stellar alternative, with similar overall particle filtration performance, similarly low operating noise, and similar overall dimensions. That said, 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, in the case of the Winix, you can easily turn off the ionizer, which has a negligible impact on particle filtration performance anyway.

  3. Best Budget Air Purifier

    If 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, 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, and it delivers good overall air purification performance, though admittedly not when the device is running at its lowest possible fan speed. All the same, this won't be a huge issue if you leave it running all night.

  4. Best Air Purifier For Small Bedrooms

    The 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 fairly easily on a dresser or shelf. However, it does lag behind its bigger sibling regarding raw performance. It does a worse job of trapping the smallest airborne particles, and its clean air delivery rate is a little on the lower end of the scale. It also runs slightly louder at its lowest fan speed, though the operating noise is still just a very low murmur.

    Unlike the Core 300, the Core 200S is Wi-Fi enabled; this allows you to change device settings, set operating schedules, and send filter replacement or cleaning notifications through the VeSync companion app. That said, there's no particle sensor, so not only can you not check ambient air quality, but the device is also incapable of automatically adjusting to differences in particle levels.

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. See our review
