Save energy by keeping your furnace or heating and cooling system clean and efficient. Clean HVAC systems and furnaces operate more efficiently. Honeywell air cleaners filter microscopic particles and allergens to help make your home a healthier place to live with cleaner air to breathe. Ordinary furnace filters may provide a bit of cleaning protection for your heating and cooling system, but most do not improve indoor air quality. You can improve the air quality in your home with Honeywell's whole-house air cleaner filters. Honeywell air cleaning filters for your HVAC or furnace are up to 60 times more effective and efficient than typical one-inch fiberglass filters AND they last up to one year! Honeywell furnace HVAC air cleaning filters are easy to install and come in a wide variety of sizes to fit all Honeywell furnace models AND most other common furnace and HVAC models such as Aprilaire, Space-Gard, Trion Air Bear, Trane or American Standard models.
