A U-shaped inlet traps pet fur ahead of the filter; independent testing found 249 CFM PM1 CADR at 5.7–8 W on daily-use speeds. The withdrawn H13 claim means it's strong HEPA-grade, not medical.

For under $200, independent testing found 249 CFM PM1 CADR, 128 CFM below 45 dBA, just 5.7–8 W on speeds 1–2, a washable pre-filter and pellet carbon. The U-shaped pet inlet is practical engineering. Its two-year warranty and bonded cartridge are less impressive, and the withdrawn H13 claim prevents treating it as medical-grade HEPA.
Low-profile, lightweight enclosure with a wall-friendly air path.
Easy pet-hair removal materially extends the main filter’s life.
Independent clean-air output is strong, but buyers should note the withdrawn H13 marketing claim.
Provides genuine odor adsorption, unlike sprayed carbon fabric.
Low, tidy rectangle with a U-shaped side/front intake that can sit nearer a wall. Excellent top controls, light sensor and auto dimming; app adds scheduling but is unnecessary for normal use.
Two-year warranty. Filters are widely stocked, but the bonded cartridge creates replacement waste; clean the optical sensor about every two months and pre-filter routinely.
