I lived in Los Angeles and San Francisco for almost a decade, including during some of the most severe wildfires the region has seen in recent years. Beneath an eerily yellow sky with smoky, stagnant air, I donned an N95 mask as a bartender—long before the pandemic made masking the norm. Needless to say, I'm no stranger to bad air and can appreciate the value of a good air purifier. Now I live in New York City, where the threat of wildfires ravaging large swaths of land is less imminent, but contaminants from cars and buses, cigarette smoke, and building and industrial emissions are ever present. Not to mention the volatile East Coast weather that's known to host newsworthy pollen spikes , and more recently, wildfire smoke drifting down from Canada. Plus, I live in a tiny apartment with a gas stove and no hood vent (yikes!), and I also have two very furry cats and a roommate who is allergic to them. So, while my focus may be less on outside air quality, I wage a daily battle fighting pet dander and microscopic allergens in my home. We tested each purifier throughout our real homes and in a sealed tent with smoke pellets. We measured visual smoke clearance, time to return to healthy air-quality readings, noise levels, room coverage, app performance, and filter design. The budget Coway Airmega Mighty2 ($270) is the best choice for most people, and the IQAir Atem X ($1,400) is our premium pick if you prioritize design and long-term repairability over price. I'm continuously testing new models to stay up-to-date with the best air purifier for every budget, room size, and pollutant.

AccordionItemContainerButton LargeChevron I have started a uniform testing method for every air purifier I test, measuring each unit’s efficacy by using a sealed tent and smoke pellets to see how quickly each air purifier clears the pellet smoke and returns the air to healthy quality when on auto mode. I measure first visually, using a timer to measure how long it takes to clear the smoke by eye. Then I measure how long it takes for the air quality to return to healthy, using both my air quality monitor and the connected app or display on the air purifier machine. I then add up the time and am able to compare models with concrete data. I also use a decibel meter on my phone to calculate noise levels during sleep and auto modes, as well as at its highest setting, since air purifiers can be egregiously loud on their most powerful setting. So for each model, I take into account how long it took on auto-adjustment settings for the air to visually clear the smoke bomb, and then use the app or machine to calculate how long it takes to measure back at healthy levels. I also use each for nearly a month, moving around my house to test in different locations: when cooking on my unventilated gas stove, under my living room window that draws in a lot of building and exhaust fumes, and outside my cat's litter box , measuring if and when the air purifier auto-engages and how long it takes to get back to clean air quality .

It's best for most homes and a great choice for anyone who wants a quiet, compact, reliable, and relatively affordable air purifier that needs minimal intervention. You just won't get some extras, like a connected app or remote. This edition has an overall bigger air-purifying system, with a prefilter to catch larger particles, a carbon filter to capture odors, and a HEPA filter to trap microscopic airborne pollutants. The latter two filters are combined into one piece that only needs to be replaced once a year—double the time of a typical air purifier filter. The Mighty2 can clean the air of up to 1,800 square feet in one hour (based on one air exchange per hour), and for smaller spaces, 900 square feet in 30 minutes (so, either one or two exchanges per hour, depending on room size). It has the brand's signature circular opening and three slits on the sides for optimum air circulation. This model also has real-time AQI detection and a MegaScan laser to evaluate a full spectrum of particles, including PM1.0, 2.5, and 10, meaning it can catch particles of microscopic virus size all the way up to pet fur. The Mighty2 has manual and auto modes, both with changing fan speeds, a sleep function, and smart settings. One of my favorite smart settings is the Mighty2's ability to intelligently adjust fan speed based on air quality so that I didn't manually have to adjust. I also liked that if the machine detects no light in the room for three minutes, it'll enter into sleep mode to conserve power and stay quiet. The touchscreen control panel features timer settings from one to 12 hours, and it displays filter life and cleaning reminders on the top display. When I tested this purifier in a smoke-filled tent, it was super-quiet, even on auto mode, only reaching about 70 decibels on the highest fan setting. It cleared smoke and restored healthy air quality in around four minutes.

I use the term “air purifier math” to consider how many air purifiers you might burn through in the next decade. One, two, maybe three? The solution to this equation shows the Atem X to be a wise investment, even at its big-ticket price. It truly is the best HEPA filter, and if you have the means, it's a worthy buy.
