Model 2400 (401)
The Aprilaire® Media Air Cleaner (formerly Space-Gard®) is a silent, low-maintenance, inexpensive air filtration system. 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%. Even the smallest particles, as small as one micron, can be filtered out at 95% effectiveness. The high-density filter unit is attached to your existing heating or cooling system, where it captures pollutants from conditioned air before it is distributed to the rooms of your home.
