SpaceGard/AprilAire Replacement Filters


Research Products Corp makes the Aprilaire® filters, which used to be sold under the Space-Gard brand name. Our Aprilaire brand of replacement media is the best to use for both Aprilaire® AND Space-Gard Media Air Cleaners. This filter utilizes an 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.



You can order your filters online, using PayPal, which offers VISA, Mastercard, American Express, Discover and eCheck. If you don't have a PayPal account, you can still make your online purchase using one of the above cards. Just select the option "If you do not currently have a PayPal account" continue processing order.
