The Aprilaire humidifier filter is a key facet in the process of introducing water vapor into your home. The "heart" of your whole-house humidifier, the Aprilaire #35 water panel (also known as Aprilaire humidifier filter, water pad, evaporator pad), is constructed of an expanded aluminum honeycomb mesh. Dipped in a clay coating, this mesh filter pad is able to absorb and hold water. As warm, dry air is forced through the Apriliare humidifier filter on its way through your whole-house humidifier, water vapor is produced and released throughout your entire indoor space.
Water vapor released into the air by the Aprilaire #35 water panel works to increase the humidity level of your indoor spaces. Achieving a proper humidity level between 30% and 50% will alleviate symptoms of dry air such as dry skin, bloody noses, and itchy eyes. Cold air holds less moisture in the air, so the humidity is lower which means dry air. In colder weather, a humidifier is a great solution to rejuvenate the moisture levels in your household.
