Types of Furnace Filters

Disposable fiberglass filters are the least expensive and also the least effective, designed to block only large dust and dirt particles to protect your furnace. Smaller particles, like pollen and mold, pass right through.

Washable electrostatic filters have a static charge that attracts dust, dirt and other matter. These filters are slightly more effective than disposable, but still block only 15 to 20 percent of airborne particles.

Pleated filters use a much denser mesh material to trap particles. The pleats increase the surface area, eliminating large allergens like pollen and mold most are 35 to 50 percent efficient. We recommend the use of Pleated Filters due to their affordable pricing and wide array of options.

Electronic air filters use electrodes to create an ionized electrical field that magnetizes pollutant particles and collects them on the filter material. An electronic unit can eliminate virtually all pollen and mold spores, up to 94 percent of smaller particles, and even up to 80 percent of airborne viruses.
