According to the 27-page lawsuit, high efficiency particulate air (HEPA) filters are strictly designed to meet specific standards for capturing small, airborne pathogens. The U.S. Department of Energy states that a filtration system must trap at least 99.97 percent of dust, pollen, mold, bacteria or other particles as small as 0.3 microns in order to qualify as HEPA, the filing relays.

Although Aroeve represented its air purifiers—specifically, models MK01, MK04 and MK06—as having HEPA-grade filters, independent laboratory testing showed that the products were “not even remotely close” to meeting the required standards, the complaint claims.

Per the case, testing also revealed that the air purifiers did not meet their claims of using H13 HEPA filters, which capture at least 99.95 percent of particles and are considered medical grade.

In 2024, a competing company challenged Aroeve’s allegedly misleading HEPA and H13 representations in a dispute brought before the National Advertising Division of the Better Business Bureau, the case says. The defendant has since agreed to remove such claims from its product pages and packaging, but the suit argues that the effort is “a day late and a dollar short.”

The plaintiff, a New York City resident who suffers from asthma and allergies, says he bought an Aroeve air purifier after smoke from Canadian wildfires drifted into the Big Apple in June 2023. As the case tells it, the plaintiff was willing to pay a premium price for the product due to its HEPA label and promises of high-quality filtration. The man asserts that he would not have bought the air purifier, or paid significantly less for the product, had he known its filter did not meet HEPA standards.

The lawsuit looks to represent anyone in the United States who purchased an Aroeve MK01, MK04 or MK06 air purifier or replacement filter during the applicable statute of limitations period.
