Most and Least Reliable Air Purifier Brands

Indeed, the main reason respondents were compelled to buy, according to our survey, was because of indoor air quality (71 percent). The second most-compelling reason people bought an air purifier was because of allergies (60 percent). “An air purifier in your home can provide a line of defense between external irritants and your lungs,” says Kollontai, “and people are becoming more keen to the benefit that brings.”

Most of our survey respondents have purchased their air purifier only recently: 64 percent bought their machines in or after 2020. For most folks, things are going well so far. Ninety-six percent of them said they never had a functionality issue with their purifier, and 98 percent of the air purifiers purchased in that 10-year period are still in operation today. Of course, your actual experience depends on which model you own—and a brand’s track record for air purifiers provides a good clue.
