I also appreciate the night mode setting, which makes everything a little quieter and less bright. A compact and easy to use air purifier that features an UV treatment technology that purifies the air twice. If you’re looking for something with a wow factor, why not blow the budget on a Dyson Purifier Cool (opens in new tab). A stylish and sleek air purifier, perfect for people who love their smart, connected devices.
Using 4 ACH—which we calculate based on a room’s volume—as a standard gives us a true picture of a machine’s capability. We also like the relatively low cost of the replacement filter, which you’ll appreciate if you need to run more than one air purifiers at the same time, or if there’s high-level pollution in the home, say from pet hair, smoke or pollen. These include tiny viral droplets, particulate matter (such as from cigarette smoke and burning wood), pet dander, dust, and dust mites. For more details, see our article on what, exactly, an air purifier can catch.
It has a four-stage purification system (most purifiers only have three), and LED touch panel, timer settings, and automatic filter replacement notifications. If you’re prone to coughing and sneezing indoors, your air quality could be to blame—and that’s where the best air purifiers come in. These powerful machines will rid your home of airborne dust mites, pesky dander, and other airborne pollutants. If you’re wondering about the overall
cost of maintenance, the LV-H132-RF Levoit air purifier filter is very affordable at about $13 per replacement. If you calculate cost based on the manufacturer’s recommended schedule, with a new filter every 6 months, you would spend about the same on filters as you do for a bigger air purifier like the Winix. It’s important to note, however, that HEPA filters will work for a very long time before they get plugged with household dust.
The evaporative technology holds the humidity at a consistent level, and is a reliable choice for humans and plants any time of the year. With a 1.1-gallon tank, this can run for up to 24 hours, and is dishwasher-safe for easy cleaning. As it so happens, there are many air purifiers you could purchase right now for just under $100.
Installing the VOC filter also lowers the machine’s CADR to just 70.6 cubic feet per minute. The Blue Pure 311 Auto also stands out for its energy efficiency, drawing just 5.9 watts on the medium setting we recommend for daily use—even less than the AP-1512HH’s thrifty 8.1 watts. And it’s especially quiet on that setting,
emitting just 33 decibels (versus the AP-1512HH’s 39 decibels) at a distance of 6 feet. In 2018, Tim also tested purifiers in Wirecutter’s Los Angeles office, attempting to simulate wildfire conditions. We do dismiss air purifiers that rely on ozone (O3, a molecule composed of three oxygen atoms) to “purify” the air.
