Why it matters
The Levoit OasisMist 1000S Smart Ultrasonic Cool Mist Tower Humidifier is an ultrasonic humidifier with a 10 liters tank.
Run time per fill, per the maker: up to 100 hours.
Aim for 40 to 60 percent relative humidity indoors: drier air irritates airways and skin, wetter air feeds dust mites and mold. Use distilled or demineralized water to avoid the white mineral dust ultrasonic mist leaves behind.
The listing names app control.
A full tank holds about 10.0 liters, which adds roughly 22 pounds of water to carry or lift to the sink and back.
Spread over 100 hours, that tank works out to about 100 milliliters an hour, the rate on the setting the run time was measured at; higher settings empty it faster.
Its stated run time of 100 hours is one of the longest run times we cover: 66 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 74 ultrasonic models we cover when we checked; the button shows today's price.
Compared with the Levoit NeoClassic 450 Humidifier: power draw 27.5 watts here vs 24 watts; tank 10 liters here vs 4.2 L; run time up to 100 hours here vs up to 42 hours.
Warranty, per the maker: 2 years.
