The AP-1512HH has also demonstrated the ability to maintain its high performance for years, even as we’ve pushed its filters far beyond their stated one-year lifespan. We ran our original test model for two years without replacing the filter, and it still performed just as well in our follow-up test as it did on day one. We ran our second test model 24/7 for four years, and again levoit filter we saw no change in performance, noise output, or reliability. When retesting our existing air-purifier picks, Tim took four measurements, two using the old filters and two using new filters, to get a picture of how (or even if) their performance changed over time. We do dismiss air purifiers that rely on ozone (O3, a molecule composed of three oxygen atoms) to “purify” the air.
You can also set a timer, see your filter’s life, and even buy a new filter within the app. Levoit products often rank highly amongst independent product reviews, and each unit we’ve tested has impressed us. From gauging customer feedback online, Levoit is often praised for its helpful customer support, with centers in the U.S., Europe and Asia. What’s more, Levoit offers special discounts through VerifyPass to active military personnel, veterans, medical staff, first responders, and teachers, which is a big plus from our point of view.

Our journalists combine independent research with (occasionally) over-the-top testing so you can make quick and confident buying decisions.
This puts its above average in our testing group though it’s not the highest performer for truly large spaces. When set to auto mode, the purifier will automatically monitor the air quality in your space and adjust the fan speeds accordingly. While those looking for further smart features can levoit air filter connect their smartphone or smart devices, such as Alexa or Google Assistant to control the unit remotely. The AirSoap, unlike all the other purifiers we have tested, does not contain a physical filter. Instead, it uses washable, electrically charged plates to capture airborne particulates.
My puppy was curious about this device that promises to help with pet dander and hair. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article.
When we researched our review of the best air purifiers, we asked experts at the California Air Resources Board if the 99.97% capture rate of a HEPA filter is enough to protect against virus exposure. While most purifiers will do an okay job if you just leave them on all the time in the background, the Levoit with WiFi can do the same thing but more efficiently. You can use the reliable smart WiFi features to make sure it filters air only when you need it. I set the schedule feature to turn the purifier on to the max speed every evening at 9pm.
If I crank the purifier up to high and put my face in front of it, the air coming out has a distinctly fresh smell to it. If you’re hoping to take the edge off the stench that’s wafting from levoit filter a laundry hamper (or maybe the clothes are just scattered all over the floor) this can do the trick.

My wife and I usually go to bed around 10pm and are awake before 7am. In order to test the sensor, I tried to put lots of dust in the air by beating some pillows and blankets. At first, I used the pillows on our bed, which must be relatively clean. I only managed to get the sensor to read “good” (one level lower than “very good”). I have a forced air HVAC system that is constantly cycling and filtering air, so I wouldn’t expect my air to be dirty very often.
It did reasonably well in our testing, removing 95.2% of the smoke on high and 89.7% on medium. But our top picks from Coway, Winix, and Blueair performed far better. The AirSoap’s claim that it will save you “thousands” in the cost of replacement filters is ridiculous—you’d have to replace the filter on the Coway AP-1512HH 20 times to reach even $1,000, which means you’d have to run it for two decades. And the need to frequently wash the plates—and, once a year, take the whole machine apart and give it a deep clean—sounds like a hassle rather than a selling point. The Honeywell InSight HPA5300B, a large-space model, likely performs well, but after measuring its electricity demands, we dismissed it. Compared with our pick for large spaces, the Blueair Blue Pure 211+, the HPA5300B is a power hog, drawing 33, 60, 94, and 117 watts on its four (low to turbo) speeds, respectively.
In 2018, he established Wirecutter’s ongoing collaboration with The New York Times’s Smarter Living. In 2017, we tested the Dyson Pure Hot+Cool Link HP02 for particulate performance in the lab and in our real-world New York apartment. It offers two distinct fan functions—diffuse and focused—and we tested it on both functions in the lab and in the real world. John Holecek further tested it for VOC removal in the lab, considering that Dyson had implemented an upgrade of its VOC filter since our 2016 test of its predecessor. In every case the HP02 offered disappointing performance relative to our top pick. Considering its high up-front cost and relatively weak performance, we can’t recommend it.
