HEPA air purifiers are air filter cleaners that that use a fan to draw the
pollutants in and captures them within a filter and send the clean air back into
the room
The Letters in the word HEPA stand for High Efficiency Particulate Arrestance.
The HEPA filter was developed during World War II by the Atomic Energy
Commission and it was designed to remove and capture radioactive dust particles
from the air which might escape and present a health hazard to the researchers.
The HEPA filter was specifically designed to protect the Human Respiratory
System.
For a filter to be labeled "True" HEPA, it must be certified 99.97% efficient in
capturing 0.3 micron (not 0.1 or 0.01 etc..) respirable-size-particles (RSP)
according to the U.S. Military Standard MIL-STD-282, commonly known as the DOP
test. The reason 0.3 micron is used and no other is because 0.3 micron is the
size at which all mechanical filters are LEAST efficient in capturing. Other
methods of testing do not give a true picture of efficiencies relative to
respirable-size-particle (RSP) capture.
The "True" HEPA filter is recognized by OSHA / EPA as the ULTIMATE in cleansing
the air and is a proven method.
"True" HEPA filters are regarded as the best form of air filtration. Hospitals,
laboratories, even NASA spend many thousands and even millions of dollars to
create contamination free environments called clean rooms to help eliminate
foreign particles, infectious agents, heavy metal particles, and a variety of
other undesirable contaminants.
A micron is a measure of length: "1 micron equals 1 millionth of a meter!". A
particle that is 10 microns or less in size is not visible to the naked human
eye.HEPA AIR PURIFICATION
By definition HEPA 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!)
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, 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.

HEPA air
purification is rapidly coming into many medical applications such as
isolation of patients under treatment involving immunological isolation, care
for burn victims, orthopedic surgery, etc.
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 0.3
microns, 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 it's two (2) to five (5) years of life.
True HEPA
Filtration helps reduce common household allergens, including: Pollen, Household
Dust, Tobacco Smoke Particles, Cat Dander, Mold Spores |
