Why it matters
The Levoit Dual 200S Humidifier is an ultrasonic humidifier with a 3 liters tank, rated for 290 square feet.
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 a top-fill tank and app control.
Top-fill tanks are filled from above without carrying the tank to a sink, which also makes them easier to wipe out.
A full tank holds about 3.0 liters, which adds roughly 7 pounds of water to carry or lift (filled in place from the top).
Its tank of 3.0 liters is one of the smallest tanks we cover: 14 of the 78 humidifiers with a stated figure come in lower, and the range runs from 0.7 liters to 20.1 liters.
Price-wise it sat in the cheapest third of the 74 ultrasonic models we cover when we checked; the button shows today's price.
It qualifies for our list Best Cool Mist Humidifiers, where it is ranked against every model that meets the same rule.
Compared with the Levoit LUH-D302-BUS Humidifier: power draw 24 watts here vs 25 watts.
