Why We Recommend HEPA Filters Over Any Other Filtration Method
The most effective air
filtration method involves a type of mechanical filter called a
HEPA (High-Efficiency
Particulate Air) filter. Developed in the 1940s by the U.S. Atomic
Energy Commission to remove airborne radioactive particles in the air, HEPA filters are used in a variety of applications including hospitals,
medical offices, and government buildings.
To qualify as a "True HEPA" filter, the filter media must be able to capture
at least 99.97 percent of all particles 0.3 microns or greater in diameter.
However, be aware of filters on the market that claim to have HEPA filters but
are only half as efficient. Insist on an air purifier that meets "True HEPA" filtration standards
in order to be certain that you get a system that removes most indoor allergen particles.
HEPA air purifiers are also
the best choice for asthma and allergy sufferers. |

Purification Technologies Explained |
Confused about air cleaners or
purifiers? Here's an explanation of the different
types of air purifiers available:
HEPA Filter Air Purifiers
By definition, a
HEPA
filter air purifier is 99.97% effective at removing particles
as small as 0.3 microns. This technology is ideal if you have
problems with dust, pollen, or any other allergens.
Ionic Air Purifiers
An ionic air purifier or
ionizer
creates negative ions which change the polarity of
airborne contaminants. These particles then fall
from the air and away from the air your breathe.
Ionizer air purifiers are silent and agood at
removing particles as well as neutralizing odors. UV
Air Purifiers
If you have a problem with mold or
bacteria, look for a
UV air purifier. This type of
air purifier emits a UV light that kills microbiological contaminants such as mold,
fungus, bacteria, and even viruses.
Carbon Air Purifiers
A
carbon air purifier
utilizes activated carbon, which behaves like a sponge
and traps most airborne gases and chemicals. If
you're concerned with tobacco smoke or odors, look for
an air purifier with a carbon filter.

Purifier Buying Tips |
Air purifiers (also known as air cleaners) are designed
to reduce airborne contaminants in your home and are
great for allergy or asthma suffers. Here are some basic
buying tips:
Find the source of your contaminants.
Indoor air pollution is quickly becoming a top environmental concern. If you're looking to purchase a
home air purifier, one of the first things you should do is determine where the pollutants are coming from. Do you live with a smoker and need to get rid of tobacco smoke odors? Do you have pets and need to filter
out pet dander? Is pollen making your allergies worse?
Each one of these pollutants is best addressed by certain air purification methods, so
find out where your contaminants are coming from.
Determine what filtration methods you need.
As a general rule, HEPA air purifiers
are versatile and will work for most indoor pollution issues. HEPA filters boast 99.97% efficiency down to 0.3 microns or 1/100th of a human hair! Look for a
HEPA air
purifier if you have a problem with pollen, pet dander, or dust. To get rid of odors, gases, or smoke, look for an air purifier with activated carbon. For mold, mildew, or other biological contaminants,
a
UV air purifier would be your best bet.
Learn what CADR means. CADR stands for Clean Air Delivery Rate. This is a certification program developed by the Association of Home Appliance Manufacturers (AHAM) to help consumers choose
air purifiers. CADR is based on the cubic feet of air an air cleaner can filter per minute. The higher the CADR number, the faster and more efficient the air purifier will be at cleaning your air.
