How to choose
Match coverage to your room
The maker coverage figures here are 1095 sq ft for the ToLife, 915 sq ft for the GermGuardian, 810 sq ft for the Coway and 968 sq ft for the Honeywell. Compare the figure against your room's floor area, and check the air changes behind it, since a figure at one air change an hour is not the same as one at 4.8.
Noise figures and fan speeds
The stated noise figures are 23 dB for the ToLife, 60 dB for the GermGuardian, 20 dB for the Coway and 45 dB for the Honeywell. The ToLife has 3 speeds, the Honeywell has 4 cleaning levels and the GermGuardian has 5 speeds. If a low figure matters to you, weigh the stated decibel number against the number of speeds each unit gives.
Filters and upkeep
The Coway uses a HEPA filter with a pre-filter and a deodorization filter, and the Honeywell pairs a HEPA filter with a pre-filter. Check the replacement reminder or indicator for your pick: the ToLife has a filter replacement reminder and the GermGuardian has a filter change indicator.
