What Is a HEPA Filter?
HEPA stands for High Efficiency Particulate Air, and a true HEPA filter is widely regarded as the ultimate filter. It was invented during World War II, when the Atomic Energy Commission needed a filter to protect researchers from radioactive dust particles that might present a health hazard to them. It traps particles as tiny as 0.3 microns with an efficiency rating of 99.97%.

To provide an idea of the size of a micron, it takes 25,400 microns to equal 1 inch (2.54 cm). In metric terms, a single micron is 1 millionth of a meter. A particle of 10 microns is invisible to the naked eye. Pollen ranges between 5-100 microns, while human hair between 70-100 microns.

The rating for a HEPA filter is based on capturing nearly all microns 0.3 in size, versus 0.1 or even 0.001 because 0.3 microns are the hardest size to trap and the optimal size for passing into the human respiratory system. Therefore, this micron efficiency rating sets the highest standard.

How HEPA Filters Work
HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.

How Much Can HEPA Filters Help?
Using a HEPA filter in your home can remove most airborne particles that might make allergies worse. But the particles suspended in air are not the only ones in your home. There are far more in your rugs, bedding, and drapes, and resting on countertops and tabletops. So it's important to keep these areas clean. It's also important, when possible, to get rid of the source of allergens and irritants. For example, the only effective way to keep tobacco smoke out of your home is to not smoke.

These filters can be part of a plan to remove irritating particles from your home. Other parts of that strategy should be to:

  • Vacuum frequently.
  • Replace carpets with wood, tile, or vinyl flooring.
  • Open windows in your home when possible -- except when pollen counts are high.
  • Keep pets outdoors if you are allergic to pet dander.
  • Change bedding frequently and wash sheets in hot water.
  • Replace draperies and curtains with wooden or metal blinds.
  • Use plastic covers over mattresses and pillows.
  • Use high-efficiency furnace filters.
