What is HEPA Air Filtration?
HEPA stands for High Efficiency Particulate Air. By definition it means a filter must be capable of capturing 99.97% of particles as small as .3 microns. (A micron is about 1/100th the width of a human hair!)
HEPA filtration technology was developed by the U.S. Atomic Energy Commission to remove airborne radioactive particles. In order to be considered a true HEPA filter, it must be capable of removing 99.97% of particles as small as 0.3microns, which is 1/75,000 of an inch, or 1/300 the diameter of the human hair. HEPA filters are used in other places such as hospitals and manufacturers' clean rooms where clean air is absolutely vital. The HEPA filter maintains its efficiency over its two (2) to five (5) years of life.
How small is .3 micron?
The air in homes, offices and schools are polluted with chemicals, organic materials particulate and microbiological. Our indoor environment contains allergens, pollutants, chemicals, gas, particles, dust mites, mold, etc. The respiratory tract - nose, sinus, and lungs struggle daily against these contaminants. Indoor air can cause headaches, red eye, digestive problems, dizziness, chronic fatigue, congestion and many other chronic and acute diseases. More than every third adult, child, or infant has allergies, asthma, and respiratory distress, or suffers the effects from sick building syndrome. Asthma is the number one leading cause of upper respiratory illness in children. HEPA air purifiers can and will provide relief for them.
Use of HEPA filters can help everyone:
have more energy,
sleep more soundly,
work more efficiently,
be more creative,
study more effectively.
HEPA filtration is rapidly coming into many medical applications such as isolation of patients under treatment involving immunological isolation, care for burn victims, orthopedic surgery, etc.Click Here to Return to the Air Purifier Page
