Review on 🌬️ Powerful H13 Smart True HEPA Air Purifier for Large Rooms up to 495 ft² - Remove 99.97% Hairs, Dust, and Smoke in Bedroom by Michelle Jackson

I'd love to see the science behind their 400 square foot display. The block is very small. The infiltration area reflects this community and is less than 2 feet by 2 feet. If it doesn't move the air, it won't clean the air. These fans, powered by AA batteries, move more air than this unit. This is sufficient for dust in a 10 x 10 room, but the lack of a charcoal insert also means odors and gases simply pass through an extremely cheap filter. 10 out of 10 not recommended.
