How to choose
Match coverage to your room
Coverage here is the maker's own figure, not a promise about a room. The GermGuardian is rated for up to 915 sq ft by the maker, the Shark for up to 1,000 sq ft, the Kenmore for up to 1,200 sq ft and the AROEVE for up to 1,095 sq ft. Measure your room first, then pick the unit whose stated coverage covers that floor area without stretching past it.
Compare filters and speeds
Filter types differ across the four picks. The AROEVE adds a high-efficiency filter with an air quality sensor and auto mode. The GermGuardian and the Kenmore give 5 speeds and the Shark gives 4 speeds, so compare filter types and speed choices side by side before you choose.
Plan upkeep and placement
The Shark suggests replacing filters every 6-12 months and the AROEVE suggests replacing the filter every 3-5 months, so plan for a replacement filter. The Kenmore display sets the mode, fan speed and timer, and the AROEVE sensor lights the indicator blue, yellow or red, so check the controls before you run the unit.
