The Aprilaire 600 Humidifier Water Panel Paper Evaporator is a "compatible"paper humidifier filter also known as the Aprilaire 35. There is also a metal filter that Aprilaire manufactures which is the Aprilaire 600 Humidifier Water Panel Evaporator (Metal). The humidifier filters works in wick style humidifiers, which draws dry air through the wet humidifier pad. When dry air passes through the wet Aprilaire 35 humidifier filter, moisture is picked up, thereby humidifying the house air. When calcium, lime and other hard water deposits collect on the Aprilaire 600 humidifier filter, it is less able to humidify the air. Utilizing replacement pads every 6 months will allow the humidifier to run less, which will maximize humidity output and save money. Mold and fungus spores can also be prevented from collecting in the air by using a clean Aprilaire 35 water panel evaporator. This is a Aprilaire "compatible" filter.
