The high-density filter unit is attached to your heating or cooling system, where it captures pollutants from conditioned air before it is distributed to the rooms of your home. 99% efficient at removing particles 1/100th the thickness of a human hair (1 micron) on a singe pass. The Aprilaire® Media Air Cleaner is silent and low maintenance. It utilizes a simple, remarkably effective HEPA-type filtering media that actually improves its particulate-capturing capability the longer it is used. For particles larger than five microns, efficiency reaches 99%.

Select an air cleaner with dimensions that most closely match your furnace's or air handler's dimensions where the air cleaner will be installed. Most air cleaners attach to a furnace's side, or air handler's bottom or top (depending which is the air inlet). Therefore, select an air cleaner with a length that does not exceed a furnace's depth, or air handler's air-inlet dimensions. (Viewing an upright furnace or air handler from the side, depth is considered the space from left to right.) View online spec sheets for dimensions of furnaces and air handlers sold here.
