Whether you worry about everyday dust and pollen or more serious pollutants like smog, mold, wildfire smoke, viruses, or bacteria, an air purifier is a worthwhile investment. That range of concerns might sound broad, but many of these pollutants have something in common: they travel through the air as particles. Larger irritants like dust, pollen, and mold spores, as well as much smaller particles from smoke, smog, and respiratory aerosols, can all be captured by a purifier as it cycles air through an effective filter.
Here are a few things to consider when choosing one:
- Recommended Room Size: Use our air purifier room-size calculator to match a purifier to your space. If you plan to run it while sleeping or working, pay attention to its coverage at quieter fan speeds too, not just at full power.
- Particle Filtration: Look for a higher clean air delivery rate (CADR), which lets a purifier clean a room faster and keep up better when air quality suddenly changes.
- Noise: If you're leaving it running for long stretches, choose a model that still cleans effectively at lower, quieter fan speeds rather than one that only performs well on high.
- Features and Maintenance: Auto modes, app controls, washable pre-filters, and an easy-to-place design all make day-to-day use more convenient.

Best Air Purifier For Most People
Particle Filtration Rate8.1Bedroom8.4Pets8.2Recommended Room Size @ Max Fan Speed37.5 m² (404 ft²)Recommended Room Size17.7 m² (190 ft²)Noise @ Lowest Fan Speed32.4dBASee all our test resultsNoise @ Highest Fan Speed60.7dBAThe best air purifier we've tested for most people is the Winix 5530. It's priced right in the middle of the pack, but it still delivers enough air-cleaning power to comfortably handle most bedrooms, home offices, and medium-to-large living rooms; so you're not paying for capacity you don't need, but you're not shortchanged either. It also holds up well at quieter fan speeds, so you can leave it running in the background while you work, watch TV, or sleep without giving up much in the way of performance. There's a good mix of useful features on top of that, too: Wi-Fi connectivity for remote control, an air quality sensor that adjusts fan speed automatically, and a Sleep mode for nighttime use. Its PlasmaWave ionization system can also be switched off independently if you'd rather not use it, and have a sensitivity to ozone.
The main catch for this air purifier is coverage. This isn't the purifier you want if you're trying to clean especiialy large or open-concept spaces with a single unit; one of our more powerful picks will serve you better there. It's also a bit larger than some competitors, though its slim, rectangular shape makes it easy enough to tuck against a wall without eating into your floor space. All things considered, the 5530's blend of solid filtration, quiet operation, convenience features, and fair pricing makes it the easiest model in this lineup to recommend for most households.

Best Air Purifier
Particle Filtration Rate9.1Bedroom9.0Pets9.1Recommended Room Size @ Max Fan Speed62.2 m² (670 ft²)Recommended Room Size30.8 m² (332 ft²)Noise @ Lowest Fan Speed31.2dBASee all our test resultsNoise @ Highest Fan Speed58.2dBAIf you want the strongest overall performance regardless of price, consider the Blueair Blue Signature Large. It's amazing for anyone shopping for an air purifier that can handle large, open spaces, but in a quiet, functional package. At its maximum fan speed, this air purifier's clean air delivery rate (CADR) is high enough for it to work as a single unit even in large, open-concept living areas. It's quite loud in this configuration, but thankfully, even at lower, quieter fan speeds, its performance is still a good match for medium-sized living areas, with its coverage in this configuration exceeding 330 ft² (30.7 m²).
One caveat, however, is that this unit's HEPASilent filter system has an ionization layer that draws particles to its electrostatically charged filter stage, which also produces ozone as an operating byproduct. While the system's ozone production level is AHAM-certified to fall within safe limits, 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. The Blue Signature Large also has a wide, squat design, but thankfully doubles as functional furniture, with a flat top that allows you to use it as an end table. You can pair this unit with your smartphone to change settings while you're away from home or, thanks to its laser particle sensor, get a fairly accurate estimate of air quality.

Best Upper Mid-Range Air Purifier
Particle Filtration Rate8.8Bedroom7.8Pets8.4Recommended Room Size @ Max Fan Speed52.7 m² (567 ft²)Recommended Room Size23.5 m² (253 ft²)Noise @ Lowest Fan Speed33.7dBASee all our test resultsNoise @ Highest Fan Speed61.2dBAAnyone put off by the Blueair Blue Signature Large's always-on ionization system should consider the Levoit Core 600S. While its clean air delivery rate falls some way short of the class-leading Blueair, the Core 600S is still far from a poor performer in this regard and is a viable option if you want a single unit for an entire studio apartment, large open-concept living and dining areas, or a larger basement space. At its highest fan speed, it can effectively handle rooms up to 567 ft² (52.7 m²), though. As far as features go, it's Wi-Fi enabled, allowing you to view an estimate of air quality, change the fan speed setting, or be alerted whenever the filter needs to be replaced.
Unfortunately, this unit is noticeably louder than the pricier Blueair at both its highest and lowest speeds, so it won't be quite as unobtrusive for overnight operation in a bedroom. That said, it still performs well at quieter fan settings, where it can effectively clean spaces up to 253 ft² (23.5 m²), making it practical for bedrooms, offices, or smaller living spaces where noise levels matter more. Its overall footprint is smaller than the Blueair, though this is still a fairly tall unit that can't be used as a table.

Best Mid-Range Air Purifier
Particle Filtration Rate7.7Bedroom8.3Pets7.9Recommended Room Size @ Max Fan Speed31.3 m² (337 ft²)Recommended Room Size12.6 m² (135 ft²)Noise @ Lowest Fan Speed32.7dBASee all our test resultsNoise @ Highest Fan Speed55.6dBAFor anyone whose space doesn't call for the muscle of the Blueair Blue Signature Large or the Levoit Core 600s, the Levoit Vital 200S is well worth a look. Its clean air delivery rate suits medium-sized spaces well, handling everyday sources like dust, pollen, and pet dander with ease in bedrooms, living rooms, and home offices. It also runs quieter than the Core 600S, making it easier to keep nearby for long periods. A built-in air quality sensor makes set-and-forget operation easy, and the VeSync app lets you adjust fan speed, monitor air quality, and set schedules remotely. It's also particularly practical in homes with shedding pets: the washable pre-filter is easy to clean as hair and larger debris build up, while the U-shaped air inlet is designed to resist clogs from pet hair and help maintain steady airflow between cleanings.
Compared to the Winix 5530, though, it gives up some room coverage and low-noise cleaning performance, which is part of why the Winix remains our pick for most people. The Vital 200S also can't keep up as well in particularly large rooms or open-concept spaces, especially if you want to run it at quieter fan speeds. Its footprint is a bit large for what it delivers, too, so it's not the easiest to tuck into tight spots. While the main particle filter isn't HEPA-certified, it still performed well in our particle-removal tests.

Best Budget Air Purifier
Particle Filtration Rate7.2Bedroom8.2Pets7.6Recommended Room Size @ Max Fan Speed23.7 m² (255 ft²)Recommended Room Size12.3 m² (132 ft²)Noise @ Lowest Fan Speed31.7dBASee all our test resultsNoise @ Highest Fan Speed58.5dBABudget doesn't have to mean bare-bones, and the Dreo Air Purifier 539S backs that up with solid small-to-medium room performance and a full suite of features. It's powerful enough for everyday use in bedrooms, home offices, and smaller living rooms, while staying very quiet at its lower fan speeds. It also matches more premium units like the Blueair Blue Signature Large on convenience, with an air quality sensor that adjusts fan speed automatically and Wi-Fi connectivity for changing settings, monitoring air quality, checking filter status, and setting schedules through the Dreo app. Its compact footprint also makes it easy to fit on a dresser or nightstand.
The main trade-off is airflow; its clean air delivery rate is a step down from the Vital 200S and the picks above, so it can struggle in larger living rooms or open-concept spaces, especially if you want to keep fan noise low. You'll also need to turn it up when dealing with a sudden spike in airborne particles from things like cooking, vacuuming, or grooming a pet, at which point the fan becomes more noticeable. Its display can also only be dimmed rather than turned off completely, and its highest-speed Turbo mode is only accessible through the app, which makes some controls a little less convenient than they could be.

Best Cheap Air Purifier
Particle Filtration Rate6.0Bedroom7.2Pets6.4Recommended Room Size @ Max Fan Speed13.2 m² (142 ft²)Recommended Room Size7.2 m² (78 ft²)Noise @ Lowest Fan Speed33.6dBASee all our test resultsNoise @ Highest Fan Speed54.7dBAIf you want to spend as little as possible and only need something for a smaller room, the Levoit Core 200S is the best cheap air purifier we've tested. It lags behind the Dreo Air Purifier 539S and larger machines, such as the Winix 5530, with a considerably lower air-cleaning rate and poorer overall performance when capturing the smallest airborne particles. That said, this device is also small enough to fit on a dresser, nightstand, or shelf, yet still offers enough airflow for bedrooms, nurseries, dorm rooms, or small home offices. It isn't powerful enough for larger living rooms or open-concept spaces, but for smaller rooms where you're sitting or sleeping relatively close to the purifier, it can still make a noticeable difference in day-to-day air quality.
It also stays fairly unobtrusive noise-wise. At quieter fan settings, it produces a soft background hum that's easy to tune out while sleeping or working nearby. Even at its highest fan speed, it remains less disruptive than many larger purifiers, though its low-noise air-cleaning performance is fairly limited. You'll need to run it at higher fan speeds to get the best performance outside of very small bedrooms or offices. While the 200S lacks the Dreo's automatic fan speed adjustment setting, it's Wi-Fi enabled, allowing you to pair it with your smartphone via the VeSync companion app to operate the device remotely, set operating schedules, or receive filter replacement notifications.

A DIY Alternative
Particle Filtration Rate9.5Bedroom4.3Pets7.7Recommended Room Size @ Max Fan Speed80.5 m² (867 ft²)Recommended Room Size54.3 m² (585 ft²)Noise @ Lowest Fan Speed51.7dBASee all our test resultsNoise @ Highest Fan Speed67.3dBAA DIY Corsi-Rosenthal Box is worth considering if convenience features, style, and quiet operation aren't priorities. We used this guide to make our own with a set of 3M Filtrete air filters and a Lasko 20-inch box fan. This homemade machine isn't nearly as practical or feature-rich as the Blueair Blue Signature Large. It's ugly, bulky, and very noisy, so it's not the best option for spaces like living rooms or bedrooms. Even at its lowest fan speed, it produces about 51.7 dBA, creating a constant fan hum that's hard to ignore in quieter spaces. At its highest setting, noise levels climb to 67.3 dBA, loud enough that holding a conversation nearby can become difficult. It also lacks niceties like particle sensors and Wi-Fi connectivity, though you could add the latter yourself using a Wi-Fi-controlled outlet. There's also no odor-absorbing carbon filter, though most air purifiers we've tested lack sufficient carbon to effectively deal with even moderate levels of volatile organic compounds.
That said, it's hard to beat the Corsi-Rosenthal Box in terms of actual performance. It offers a very high clean air delivery rate, sufficient for big open-concept living spaces up to 867 ft² (80.5 m²). More impressively, it still maintains excellent low-noise filtration performance, effectively handling spaces as large as 585 ft² (54.3 m²) even at quieter fan settings. If you plan to set it up in an area where noise, size, and aesthetics aren't a concern, such as a workshop, garage, basement, or utility space, it's hard to do any better. It's also worth noting that some iterations of the Corsi-Rosenthal Box utilize multiple PC case fans instead of a single box fan, which is intended to help reduce operating noise and boost efficiency. That said, we've yet to build a Corsi-Rosenthal Box in this manner, so we can't personally guarantee how it performs.
