Changing or cleaning the furnace filter is one of the easiest things you can do to prolong the life of your heating and air conditioning system – and keep it operating efficiently.
E.R.S. sells and installs all types of filters for your furnace system. Please contact us if you need a new filter for your heating and cooling system.
Types of 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 “allergy” 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.
Electronic air cleaners 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.
