For big spaces, the Coway Airmega 300 is tops. We also cover air purifiers that perform nearly as well, air filters for whole-house heating systems, and discuss what type of air purifier to avoid at all costs. In expert tests and user reviews, the Coway AP-1512HH Mighty excels at particle, pollen and smoke removal. It doesn’t have the largest capacity, but with the ability to clean air in rooms of up to 326 square feet, it can handle all but the largest master bedrooms. Speaking of bedrooms, the Coway is among the quietest air purifiers in testing, “effectively silent” at its lowest setting one top expert reports.
Good durability and low long-term ownership costs are pluses, too. Room size — Up to 1,250 sq. It’s overkill for a bedroom, and loud at its high speed, but if you live near a highway, or want an air purifier for an oversized space, such as a great room, the Coway Airmega 300 is a top choice. Furnace filters cost significantly less than air purifiers, and experts say they can be just as effective for most people. The 1550 gets very high ratings in professional tests.

Users like them, too, and many say that they effectively help reduce allergy symptoms. Portable Air Purifiers If you suffer from allergies, asthma or any other condition that’s made worst by airborne particles, a room air purifier may provide you with some — or quite a bit — of relief. Furnace Filters Rather than purifying air one room at a time, another alternative is to consider a whole-house furnace filter. Can air purifiers help you breathe easier? In reviewing air purifiers, we discovered that the most satisfied customers are those who understand the limitations of an air purifier and adjust their expectations accordingly. Air purifiers do their work using different technologies, and some use multiple technologies, to deal with airborne pollutants. Reviewers say this type of air purifier is by far the most effective.
These models don’t produce any ozone, either. Some air purifiers use electronic technology in place of or in addition to a mechanical filter. Electronic ionizers work by reversing the charge of particles in the air. The charged particles are then passed back out to the room where they are attracted to objects such as clothing, walls, floors and furniture. In effect, particles are removed from the air and deposited on your furnishings and clothing. While both types of electronic air purifiers are effective, they can also produce a small amount of ozone, a lung irritant, though typically at levels below the standard set as safe by Underwriters Laboratory and by government agencies. Some electronic air cleaners put a small charge on a mechanical filter to help it collect particles more effectively.
With that type of air cleaner, the charge is low enough that measurable amounts of ozone are not produced. Ionic and electrostatic air purifiers emit small amounts of ozone as a byproduct, but ozone generators sold as air purifiers emit high levels intentionally to neutralize chemical irritants and odors. Research has shown that, while this can be effective, it’s also fairly dangerous. The best advice we found is to avoid ozone generators altogether. As noted above, with the exception of ozone generators, none of these mechanical or electronic air purifying techniques are particularly effective against chemical gases or strong odors. Some air purifiers add some type of chemical filtration — typically activated carbon — to deal with those irritants. For its part, Consumer Reports notes in its review that “Some portable models with carbon pre-filters are claimed to filter VOCs, but the Environmental Protection Agency warns that such filters are specific to certain gaseous pollutants, not for others, and that no air purifier is expected to remove all gaseous pollutants found in the typical home.
Finally, we analyze the full cost of the unit, which includes both the initial cost and the ongoing costs of filter replacement. The results of that research helps us to narrow down our recommendations for the top air purifiers for any space or budget. This Coway air cleaner is rated for rooms up to 326 square feet, making it suitable for all but the largest master bedrooms. Wirecutter’s test — “far quieter than a typical conversation,” John Holecek and Tim Heffernan report. At its lowest setting, this air purifier “is effectively silent on low at 42. That all wouldn’t matter if the air purifier wasn’t a capable performer, but it is — “reducing particle concentration to just 12 percent background level after 20 minutes,” Holecek and Heffernan say.
