Guide to Aprilaire Humidifier Replacement Filters

A humidifier is an excellent addition to your home for combating dry indoor air and adding moisture for comfort. These systems include filters that help release clean, humidified air throughout your living space. Aprilaire produces popular, high-quality humidifiers known for effectively removing airborne particles and maintaining a cozy environment.

The filters used in Aprilaire humidifiers are also called water panels, evaporator pads, or water filters. They vary according to the specific model and are readily available at major retailers like Home Depot, with prices starting around $10.

Compatible with numerous brands, Aprilaire filters are primarily used in fan-powered and large bypass humidifiers. Made from elongated mesh pads of aluminum coated with a clay-like substance, they help prevent mineral and water deposit buildup. During operation, water flows into the humidifier, saturating the filter. The fan then blows dry, heated air across the moist filter, generating water vapor.

This vapor disperses into your home through the duct system, increasing humidity. To maintain optimal performance, it's important to replace the filter annually or after each heating season. Regular replacement of quality filters like Aprilaire’s ensures a healthier environment and improves your home's energy efficiency.
