How to choose
Coverage for small rooms
Coverage is the first split: the POMORON is rated for 1,250 sq ft, the HealthSmart for 300 sq ft and the GermGuardian for 50 sq ft. Match the maker figure to your room size. The GermGuardian is a 7-inch wall-pluggable unit, the HealthSmart plugs into any outlet, and the POMORON measures 6.34 by 6.34 by 11.81 inches.
UV light and filters
All three picks use a UV light, but only the POMORON pairs it with a True H13 3-layer filter and an ionizer. The GermGuardian and HealthSmart are UV sanitizer units, so compare them on size, coverage and controls rather than filter stages. The POMORON filter removes 99.97% of airborne particles as small as 0.3 microns.
Timers, speeds and noise
The POMORON lists an 8, 12 or 24-hour timer and 4 fan speeds. The GermGuardian runs at 45 dB and the HealthSmart at 10 dB, while the POMORON sleep mode runs at 25 dB. Compare the stated decibel figure with your room, and check the timer and speed count before you buy.
