A proposed class action lawsuit alleges that Clorox and Hamilton Beach Brands have falsely marketed their Clorox 11030 Air Purifier as equipped with a high efficiency particulate air (HEPA) filter when, in fact, the standard filter that comes with the product and replacement filters do not meet HEPA standards.

According to the 21-page complaint, Clorox deceived consumers about the purported HEPA air filters so as to sell the 11030 Air Purifier at a premium price. Per the case, independent testing performed by the plaintiff’s counsel revealed that the filters in the products, as well as replacement filters sold by the defendants, fall short of HEPA standards.

Without the alleged deception, the plaintiff argues, reasonable consumers would have been willing to pay less for the air purifiers—or not bought them at all.

“Defendants knew this, but continued hocking their wares, making a killing selling the Air Purifier and replacement filters since the outset of the COVID-19 pandemic,” the class action lawsuit charges.

To meet HEPA standards, a filter must remove 99.97 percent of all dust, mold, bacteria, and other microscopic particles, the lawsuit explains. However, an independent laboratory hired by the plaintiff’s counsel determined the Clorox filters removed only 99.83 percent of particles in the air, meaning their efficacy does not meet the threshold for HEPA compliance, the filing says.

The suit argues that Clorox was aware that its filters weren’t up to HEPA standards but advertised the products as meeting HEPA standards anyway, so as to influence consumers into paying a higher price.

The suit relays that the COVID-19 pandemic and drastic uptick in wildfire smoke caused a surge in the demand for air filters, with the air purifier market expected to balloon to $25.26 billion in 2030. The case accuses Clorox of capitalizing on widespread contamination fears while failing to disclose that its air purifiers had no actual HEPA filtration.

The lawsuit goes on to allege that the defendants were “in a position to know (and did know) the true quality and capability of their Products but affirmatively warranted that the Products had a greater purifying ability than they actually did.”

The plaintiff is a California resident who purchased the 11030 Air Purifier in May 2025. Per the suit, the plaintiff chose this particular model of air purifier after reviewing information that stated the device had a HEPA filter.

The lawsuit maintains that the plaintiff would not have bought the air purifier had they known it was not equipped with a HEPA filter.

The Clorox air purifier lawsuit looks to cover all consumers in the United States who purchased a Clorox 11030 Air Purifier within the applicable statute of limitations period.
