How to choose
Match coverage to room size
Coverage is the maker's own figure, so compare it with your room. The ECOSELF is rated for up to 1,800 sq ft by the maker, the Coway for up to 1,748 sq ft and the GermGuardian for up to 743 sq ft. A larger figure suits a larger room, while a smaller room needs less coverage, so measure your room before you choose.
Filters for cooking odors
Cooking smells are odors, and each pick handles them with its own filter. The GermGuardian pairs its HEPA filter with an activated carbon filter for odors from cooking, and the ECOSELF has an activated carbon layer for everyday smells. The Coway combines a pre-filter, a deodorization filter, and a HEPA filter. Compare the odor filter, not just the HEPA filter, when cooking smells are the need.
Noise, timers and upkeep
Noise figures decide bedroom use: the ECOSELF sleep mode runs at 20 dB, the Coway at 24.4 dB and the GermGuardian at 55 dB. Timers help too: the ECOSELF has a 1 to 24 hour timer and the Coway has a timer. For upkeep, replace the ECOSELF filter every 3 to 6 months and watch the Coway filter indicator.
