"A feature-rich purifier whose clean air delivery rate cannot possibly match its marketing claims."
The '2,400 sq ft in 30 mins' claim is a calculation based on one or two slow air changes per hour. For meaningful removal of allergens and particulates, as recommended by health associations, this unit is realistically sized for a room under 400 sq ft.
This unit is for a buyer on a strict budget who prioritizes features like an air quality display and auto mode for a small bedroom or office. You are buying for the control panel features, not for verified performance in a large space.
Anyone with significant allergies or asthma should skip this due to the lack of a verified CADR rating. Buyers concerned with long-term running costs should also avoid it until the replacement filter price is known.
