Home > Air Filtration > Permanent Electrostatic Furnace Filters

Permanent electrostatic furnace filters are a convenient alternative to traditional disposable filters. They are made of a special charged filter material that attracts and traps airborne particles to clean the air in your heating system before it is distributed throughout your home. The filters work better than traditional filters, trapping more dust and particles while offering low airflow resistance to minimize strain on your forced air system.

Installing your new electrostatic furnace filter is a breeze. The permanent furnace filter goes into your furnace the same way as your old filter, but it is permanent so you never have to worry about finding the right size filter again. Instead of changing your filters, simply remove the permanent electrostatic air filter from your appliance, rinse it with water, let it dry and re-install it.

Our air filters come in a variety of common sizes, or you can order a custom-cut filter. Consult your old filter or your furnace paperwork to find which size you need. If you need more than one filter, we offer volume pricing on orders of 2 or more filters for an unbeatable value.
