Top Fill Design

The EssickAir® 9-Gallon Top Fill humidifier adds invisible moisture to your home by moving dry inlet air through a saturated wick. As air moves through the wick, the water evaporates into the air, leaving behind any white dust, minerals, or dissolved and suspended solids. Because the water is evaporated, there is just clean and invisible moist air.

To help reduce bacteria growth and keep maximum efficiency, the filter should be replaced at least once per season depending on use or water conditions. It is also recommended to clean the base and tank bi-weekly depending on use.

Assembled in Little Rock, Arkansas using components made in both the US and China.
