How to choose
Read coverage as the maker's figure
Coverage is the first split in this list. The LabCharge and the Shark are each rated for up to 250 sq ft by the maker, while the Honeywell is rated for up to 530 sq ft by the maker. Match the rating to the room where the unit will run, and check the rating before you compare size or weight.
Filters and controls compared
Filter design splits these three. The LabCharge runs filter-free on ions with touch control, while the Shark pairs a HEPA filter with washable Debris Defense screens and a control panel that shows air quality, filter life, fan speed and Eco mode. The Honeywell runs 3-in-1 filtration with button control, 3 cleaning levels and a timer. Compare the filter set and the controls against what you want to adjust each day.
Placement and upkeep
Put the unit where air can move around it and where the controls stay easy to reach. The LabCharge plugs in with a wall plug and a USB cable, so it fits on shelves, nightstands and countertops. For the Shark, the screens can be vacuumed, wiped or rinsed clean, and for the Honeywell the filter change indicator shows when to check the filter. Check the indicator or the screens on a regular schedule.
