Arvin humidifiers are vital to release humidity back into the air. Humidifiers are important appliances in buildings where furnaces are being run all winter long. Arvin's humidibelt replacements (also known as evaporator pads) aid your humidifier process by filtering the water the system uses. Be sure to change your filter twice a season to ensure that moisture quality remains high
