HEPA filters have been traditionally
used in hospital operating and isolation rooms, pharmaceutical
and computer chip manufacturing, and other application requiring
"absolute" filtration. Today HEPA filters are used in a wide
variety of critical filtration application in the nuclear,
electronic, aerospace, pharmaceutical and medical fields,
and in equipment for asbestos abatement.
HEPA filters are highly recommended
for allergy sufferers. The High Alpha Hepa filter meets the
strict Military Standard 282 filtration efficiency test.
Why Use a HEPA Filter Vacuum?
For
allergy and asthma sufferers, vacuuming can turn into a never-ending
battle. Even the most valiant of vacuum cleaners may succumb
to the battle and help cause a sneeze when allergens rear
their nasty little heads. One of the reasons this may happen
is that your tried and true vacuum cleaner is simply exhausting
dirt every time you use it! Even expensive vacuum cleaners
are left in the dust without adequate filtration. In order
to have a fighting chance against indoor pollutants, a HEPA-filtered
vacuum cleaner is the best, most cost effective way to help
you control your environment.
First, let us look at some important
facts pertaining to particle sizes:
Small particles are generally measured in fractions of a meter
or "microns." One micron equals one one-millionth of a meter.
The following chart contains the particles sizes of some common
items:
- Human hair 80.0 - 100.0 microns
- Dust mite waste particles
10.0 - 24.0 microns
- Mold 4.0 -+ microns
- Pollen 10.0 - 40.0 microns
- Bacteria 0.3 - 50.0 microns
- Asbestos (fibers) 3.0 - 20.0
microns
- Particles below 10 microns are
invisible to the human eye. -
The most common airborne particle size is 2.4 microns.
- The most harmful Respirable
Size Particle (RSP) is 0.3 microns.
- The average vacuum cleaner
only filters particles from 30 to 50 microns, thus exhausting
harmful respirable allergens back into the air.
Now let us look at the facts
