HEPA Air Filter | Hepa Air Purifier | Ionic Air Purifier

Updated on October 9, 2009

HEPA is an acronym for "High Efficiency Particulate Air" or known as ionic air purifier. Fundamentally HEPA air filter or Hepa air purifier is a type of filter that trap a large amount of small particles in the air rather than recirculate back into your house and have been around for some time. In the 1950s the US Atomic Energy Commission needed something to remove small particulates that are radioactive. Since then HEPA air filter or Hepa air purifiers have been using this technology to clean the indoors in room units to beauty parlors. A true HEPA air filter or Hepa air purifier or ionic air purifier are able to trap at least 99.97 percent of particles of .3 microns.

HEPA air filter only allow very tiny particles to pass through into circulation. Most of the indoor air contains pollutants and toxic chemicals with a variety of airborne particles like: mold spores, dust mites, pollen, smoke, pet dander, ionic substances and chemical fumes from modern household furniture and other household cleaners. These airborne particles could carry bacteria, mold, and viruses. Every breathe you take stands to fight fatigue symptoms, illnesses, allergic reactions and many more hidings in the air. A houseplant can help remove some ionic and toxic impurities but cleaning your home and the air you breathe with fresh, clean air is easy with the use of ionic air purifier just like HEPA air filter and HEPA air purifying systems.

If we place a single sheet of this HEPA air filter's paper unit in front of a fan as if an air purifiers, very little air would be able to pass because of the small size of the holes. Now if we double the size of the sheet we would get twice the airflow and filter life. Instead let us try folding the paper back and forth so that we can present a very large surface area to the airflow and thus the ionic air purifier such as HEPA air filter system made this very efficient. This is how real-world HEPA air filter are made in real HEPA systems. Some have as much as 40 square feet of the filter material folded into the HEPA section. It also does not look like a screen or a colander. Instead it looks like a very thin bail of fibers. Thus the air has to find a route through this maze of fibers. Therefore, this ionic HEPA air filter or air purifier stop mold spores as well as many bacteria and viruses and of course larger items such as dust.

Unfortunately, HEPA air filter does not remove odors, chemicals or gases because these molecular substances are larger than the 0.3 micron. Therefore typical ionic HEPA air purifiers and filters have some level of activated carbon-based material to absorb odors and chemicals. The activated carbon unit comes into a number of varieties. This varies from a thin mat in an Air-O-Swiss unit, to pounds of activated carbon in an Austin Air Purifier. These carbon element absorbs gases that are not trapped by the HEPA air filtering systems and other ionic air purifiers. These chemicals are either harmful gases or those that cause odors.

HEPA air filter or air purifiers are easy to operate and this portable ionic air purifier can be easily moved from one room to another. However, the purifying range will be quite limited but the portability saves money on installation.
