SpaceGard Air Filters from AprilAir for cleaner whole-house air

The Space Gard High Efficiency Air Cleaner from Aprilair (sometimes misspelled Space Guard) is a complete air cleaning system. It effectively cleans up air pollutants such as pollen, dust, dander, pet hair, dust mites and tobacco smoke. The cleaner was first released in 1973 and ever since has been reputed to be a silent worker, with relatively low maintenance and mostly inexpensive.

Space Gard 201 Uses HEPA Technology
The Space-Gard 201 filter uses a HEPA-type filtering science (highly efficient particulate air filter) that is said to be 99% effective against dust, pollen, mold and bacteria larger than five microns. For particles smaller than that size a 95% effective rate is quoted. With HEPA, these particles are trapped by the Space Gard 201's fibers by diffusion, interception or impaction. The SpaceGard air cleaner claims to be an improvement over regular HEPA science, and is said to actually improve over time and with more use.

When comparing “living air purifiers” (products by Ecoquest which is a spin off of Alpine) to Space-Gard models you notice many differences. While Ecoquest is known for its quality and variety of air purifying products, their models are electronically and ionically based. For one thing, Space-Gard cleaners have no moving parts and thus do not have all the maintenance of living air purifiers. SpaceGards do not use any large amounts of electricity nor are they noisy, whereas other types of cleaners are notorious for both. Space-Gards come with a limited lifetime warranty.
