Why it matters
The Levoit Superior 6000S Smart Evaporative Humidifier is an evaporative humidifier with a 6 gallons tank, rated for 3,000 sq ft.
Run time per fill, per the maker: up to 72 hours.
Aim for 40 to 60 percent relative humidity indoors: drier air irritates airways and skin, wetter air feeds dust mites and mold. Evaporative wicks trap the minerals instead of releasing them, so tap water is fine, but the wick stiffens and needs replacing.
A full tank holds about 22.7 liters, which adds roughly 50 pounds of water to carry or lift to the sink and back.
Spread over 72 hours, that tank works out to about 315 milliliters an hour, the rate on the setting the run time was measured at; higher settings empty it faster.
Its stated run time of 72 hours is one of the longest run times we cover: 63 of the 69 humidifiers with a stated figure come in lower, and the range runs from 10 hours to 130 hours.
Price-wise it sat in the dearest third of the 22 evaporative models we cover when we checked; the button shows today's price.
