Honeywell filters are up to 60 times more effective and efficient than typical one-inch fiberglass filters, and last up to one year. They are easy to install and come in a wide variety of sizes to fit all Honeywell, and most Aprilaire®, Space-Guard®, and Trion Air Bear® furnace models. We also carry filters that fit the Trane or American Standard PerfectFit™ models.
All Honeywell Whole House/Media Filters have MERV ratings (Minimum Efficiency Reporting Value). MERV measures an air filter's effectiveness. The higher the MERV rating, the more air particles a filter captures – and the cleaner the air you and your family breathe! MERV ratings are based on the ASHRAE 52.2 test designed by the National Air Filtration Association.
