Why it matters
The Vivosun H05 Humidifier is an ultrasonic humidifier with a 5 liters tank.
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 5.0 liters, which adds roughly 11 pounds of water to carry or lift to the sink and back.
Its tank of 5.0 liters is above the middle of the range we cover: 44 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 middle 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 Vivosun H09 Humidifier: power draw 30 watts here vs 32 watts.
