1" Depth Air Filters

Air and furnace filters with a 1-inch depth are available in five different levels of filtration: Basic, advanced, premium ultimate and elite. Choose the right filtration level for your home based on the impurities that are filtered out. While all filters with 1-inch depth remove lint, dust, dander, mold spores and pollen, only a select few are powerful enough to reduce odor, fine dust and bacteria. Use the comparison chart below to find the right 1-inch air filter for your home.
