HEPA Furnace Filters

A lot of people wonder about using HEPA filters for their home’s air conditioning and heating system, and this is a great question. HEPA, which stands for High Efficiency Particulate Air filters must capture at least 99.97% of all particles that are 0.3 microns in diameter or larger. One micron is one millionth of a meter, or one thousandth of a millimeter and is some 300 times smaller than a human hair diameter. HEPA filters can filter out particles that are too small to see with the unaided eye.

It turns out that HEPA filters can be used with home furnace and air conditioning systems, and they are among the most efficient available. A HEPA filter removes almost all the allergens that are routed through a home furnace or air conditioning system. They remove pet dander, dust mites, mold spores, pollen, and other common home allergens.

HEPA filters are often used in places where the air must be clean, such as in hospital rooms, clean rooms for high-tech manufacturing, surgery suites, and other places where the maximum particle filtration is of utmost importance. They are also used in appliances like HEPA air purifiers and on vacuum cleaners. One choice of HEPA furnace filter is the RiteAir HEPA-Pure, a filter that has over 7 pleats per inch, giving the filter the maximum surface area for catching particles. Filters like the HEPA-Pure can be vacuumed multiple times to extend the time between replacement.

HEPA furnace filters are great choices for providing relief for those who have asthma or allergies because of their superior ability to trap pollen, pet dander, mold, skin flakes, and other airborne particles. If you do choose a HEPA furnace filter, it is very important that it be maintained faithfully. Once a HEPA furnace filter becomes clogged, air flow through the furnace system will be greatly reduced, and the filter will be to clogged to do much good.

HEPA furnace filters in some ways look like regular filters. However, the filtration material in HEPA furnace filters is different from the filtration materials used in regular filters in that it is a denser material to be able to catch small particles. Additionally, HEPA furnace filters are pleated, giving the filter the maximum amount of surface area for filtering particles out of the air. The pleats also have the effect of extending the useful life of a HEPA filter, because dust will collect in the deepest folds of the pleats first, whereas if the filter were not pleated, the dust would clog the HEPA filter much more quickly.

HEPA furnace filters make a great choice for home furnace and air conditioning systems. They come in the same standard sizes as normal furnace filters, though they cost more. On the other hand, with proper maintenance, HEPA furnace filters can outlast regular filters due to their pleated design. They are very efficient at keeping the air inside your house clearer from allergens such as pollen, pet dander, and mold.

  1. If you have a very airtight house that gets stuffy, select a HEPA model that introduces filtered fresh outdoor air into your duct system.
    Thanks for having a great post!
