HEPA FILTERS
High Efficiency Particulate Air (HEPA) filters are the highest efficiency
air filters available for the filtration of small particles. Defined
by the Institute of Environmental Science, a Certified HEPA filter
must capture a minimum of 99.97% of contaminants at 0.3 microns in
size.
The first HEPA filters were developed in the 1940's by the USA Atomic
Energy Commission to fulfill a top-secret need for an efficient, effective
way to filter radioactive particulate contaminants. They were needed
as part of the Manhattan Project, which was the development of the
atomic bomb. The first HEPA air filters were very bulky compared to
the HEPA air filters that are produced today. HEPA filter technology
was declassified after World War 2 and then allowed for commercial
and residential use.
HEPA air filters have been traditionally used in hospital operating
and isolation rooms, pharmaceutical and computer chip manufacturing,
as well as in other applications requiring "Absolute" Filtration.
Today HEPA air cleaners, vacuum cleaners and air filters are used
in a wide variety of critical filtration applications in the nuclear,
electronic, aerospace, pharmaceutical and medical fields. HEPA air
cleaners, vacuum cleaners and air filters are required by law to
be used in all equipment for asbestos, lead, toxic chemical and mold
abatement.
These HEPA filtered products must meet the strict Military
Standard 282 HEPA filtration efficiency test.
