Why it matters
The Smartmi SKV6004EU-G Humidifier is an evaporative humidifier with a 4 liters tank.
Run time per fill, per the maker: 24 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.
The listing names a top-fill tank, automatic shut-off 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 4.0 liters, which adds roughly 9 pounds of water to carry or lift (filled in place from the top).
Spread over 24 hours, that tank works out to about 167 milliliters an hour, the rate on the setting the run time was measured at; higher settings empty it faster.
Its tank of 4.0 liters is below the middle of the range we cover: 33 of the 78 humidifiers with a stated figure come in lower, and the range runs from 0.7 liters to 20.1 liters.
Its stated run time of 24 hours is one of the shortest run times we cover: 4 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 middle third of the 22 evaporative models we cover when we checked; the button shows today's price.
It qualifies for our lists Best Cool Mist Humidifiers, Best Evaporative Humidifiers, where it is ranked against every model that meets the same rule.
