Press Release Summary = When it comes to air filter efficiency, it's important to
understand the unique, measurable differences offered by genuine HEPA Filters. HEPA
Air Filters undergo specific measurable testing not always required of other filter
media.

Press Release Body = When it comes to air filtration and air quality, there are few
commercially or residentially available systems that can rival HEPA (High Efficiency
Particulate Air) filters and HEPA filtration systems. The difference is in what we
can't see-an ability to remove 99.97% of all airborne contaminants at .3 microns and
smaller in the air-a performance that's largely unmatched in non-HEPA equivalent
systems.

"The HEPA difference makes all the difference when it comes to filtering particles
from the air," says Dave Hearn, President of PureAir Systems, Inc. "It's important
to look very closely at how an air filtration system is tested, because the smallest
particles that pass through other systems are almost always caught by HEPA-based
systems. And the smallest of particles are almost always the most potentially
harmful to us."

Obviously, the ability to remove virtually 100 percent of harmful respirable
particles from the air offers cleaner, healthier indoor air quality. Less apparent
to the average consumer is how filter efficiency ratings are determined-a critical
distinction and difference between what initially might seem to be similar air
filters and filtration systems

HEPA air filters are the only mechanical air filters tested and certified to meet a
specific efficiency at a specific particle size. All HEPA air filters must meet a
minimum efficiency of 99.97% at 0.3 microns-3 millionths of a meter. Non-HEPA
filters are required to provide an efficiency rating, but not necessarily a rating
that is based on particle size. Since many of the respirable particles that are
harmful to us are usually less than 2 microns in size, it's vital to know what size
particles a filter removes from the air.

In fact, a filter that boasts 95 percent efficiency without a particle size
measurement, may actually remove little, if any, of the harmful particles at 0.3
microns or fewer.

"HEPA filters are used in high-tech manufacturing, hospitals, and sterile clean
rooms around the world." Hearn added, "That's the technology we bring to the table
in our systems. That's the technology I want protecting my family."
