(checked 2026-10-10)
A tiny, very quiet and efficient purifier for bedrooms and dorms, but it is bare-bones (no auto mode or app), only suits small rooms, and some owners say it broke within a year.
Top complaints
- Only for small rooms, no extras
Wirecutter calls it very basic, with no smart functions and no auto mode, and suited to rooms under about 180 sq ft. Expert Reviews says it is less powerful than some rivals.
