Product Description

The evaporator sleeve, sometimes called a humidifier pad, media filter, or water filter, absorbs water from the pan within the humidifier. The sleeve fits over the drum assembly, which slowly spins and picks up water to circulate as humidity into the air. The sleeve should be replaced at least once a year to ensure optimal performance. This sleeve is also available as part of the GeneralAire 81 tune up kit, which provides everything necessary to make your humidifier like new.

This component is also known as part number: 7099

The manufacturer is sometimes referred to as General Filters, General Air but is correctly spelled GeneralAire®.

Was quite relieved to find the evaporator sleeve on your website since the humidifier is getting up there in years but still working very well. No problems at all installing the sleeve. Thank you so much.

Good product - hard to install by T.L. Hall (Bloomfield Hills MI US)

Definitely a necessary item since I live in an area with a lot of minerals in the tap water. Could be improved with better instructions as to how to remove the drum for installation. Maybe an on site video...
