Hearth HEPA Air Purifier Review

The Hearth pulled down particulate readings quickly in a mid-size living room, and its auto mode ramped sensibly when we seared food nearby. On the low and sleep settings it was quiet enough to forget it was running.

Ongoing filter costs are the thing to budget for, as with any true-HEPA unit, and this model skips app control. Neither dented our enthusiasm — for clean air without the noise or the premium price, it's the one we'd buy.
