HEPA Vacuum Cleaner
HEPA Vacuum Cleaner Filtration System
Allergy sufferers know that microscopic particles in the air can be a real pain. Even particles that cannot be seen can be felt – reddening
the eyes, making breathing difficult and generally causing pain and discomfort. Even people who are lucky enough not to suffer from allergies may
have family and friends who do. For these reasons, maximum efficiency when vacuuming is a must. A vacuum cleaner with HEPA filtration is the
pinnacle of scientific achievement when it comes to cleaning the air in your home.
What Is a HEPA Vacuum Cleaner?
HEPA filter stands for “High Efficiency Particulate Air” filter. Through a patented process derived from decades of research, the
HEPA filter is built with millions of tiny interwoven fibers. Vacuum cleaners use HEPA filters to clean the exhaust air that is put back out
into your home. Cleaner air means less allergies and a cleaner home. Through mastery of the physics and movement of the microscopic
particles, HEPA filter vacuum cleaners trap 99.97 percent of mold, bacteria, dust and pollen.
Technical Specifications of HEPA Filtration
HEPA filter vacuum cleaners are equipped to remove particles from the air that range in sizes of approximately 0.3 micrometers. To say that
these particles are undetectable to the naked eye is a serious understatement. The efficiency rating of 99.97 percent is based upon the
scientific presumption that all particles would be 0.3 micrometers, which is actually the most difficult size particle to be trapped in the
Particles that are larger or smaller than that are trapped more easily. This means that 99.97 percent is actually the “worst case scenario”
for the efficiency percentage. Since the particles in your home are undoubtedly larger or smaller than exactly 0.3 micrometers, the HEPA filter’s
true efficiency rating is considerably higher than even 99.97 percent.
Origins and Early Usage
The lineage of today’s modern HEPA vacuum cleaners can be traced back to the 1940s and 50s when HEPA filtration was
used to clear the air of radioactive particles resulting from nuclear testing. Since then they have been used in fields as diverse as
biomedicine, computer micro-circuitry and aerospace engineering. If HEPA filtration can do all of these things, just think what a HEPA vacuum
cleaner can do for your home. The technology behind these vacuum cleaners is amazing. The key to achieving this 99.97 percent or better rating in
your own home is proper usage and care of the vacuum cleaner.
