How does activated carbon filtration protect your health?
If you're just beginning your air purifier search, the benefits of
activated carbon filtration may not be foremost in your mind. You may
be more concerned about relieving allergies or asthma, leading you to
think in terms of irritants like dust, pollen, and dander.
However,
the odors and chemicals in your home and workplace are also of serious
concern. Because of the health effects of chemical contaminants better
quality air purifiers include activated carbon filtration.
Activated carbon air filters are the most effective type of filter against chemicals, gases, cigarette smoke and odors.
Using
activated carbon for air purification will make your air healthier and
more pleasant. You will especially benefit if you suffer from Multiple
Chemical Sensitivity (MCS) or any hyper reactive airway disorder that
makes you sensitive to chemical pollutants.
Is activated carbon filtration effective?Air
purification with activated carbon air filters is the single best way
to remove chemical pollutants from the air. Activated carbon can adsorb
as much as 60% of its weight in pollutants.
Activated
carbon filters will adsorb some of almost any vapor. They have a large
capacity for organic molecules, especially solvents. Activated carbon
can adsorb and retain a wide variety of chemicals at the same time.
Activated
carbon air filters work well under a wide range of temperatures and
humidity levels; are inert and safe to handle and use; and are readily
available and affordable.
Activated carbon filtration can remove
organic acids, alcohols, aldehydes, chlorinated hydrocarbons, esters,
ethers, ketones, mercaptans, amines, halogens, halogen acids, sulfuric
acid, sulfur dioxide, phosgene, as well as odors from human and animal
sources, urine and other waste, perfumes and household cleaning
chemicals.
You should be aware that while activated carbon is
excellent for removal of volatile organic compounds (VOCs), some
compounds like formaldehyde and inorganic gases respond best to
chemisorbers that break down the pollutants by chemical reaction.
You
should look for air purifiers containing activated carbon impregnated
with appropriate chemisorbers and catalysts to control the particular
pollutants that concern you.
Using special activated carbon blends
Depending on the chemicals and odors you wish to control you may need to select a specialized activated carbon filter.
Activated
carbon blends with differing properties result from the source of the
activated carbon, the methods used to create it, and any added
chemisorbers and catalysts. These catalysts and chemisorbers enhance
the adsorption of specific pollutants such as volatile organic
compounds or cigarette smoke.
However, few air purifier manufacturers offer you any opportunity to select a custom activated carbon blend.
I
have found that Allerair air purifiers, with over forty different
activated carbon blends available can meet anyone's needs with ease.
Allerair can also provide highly customized blends for special purposes
to labs, industry, military or anyone with needs beyond the usual
residential, health care, or commercial uses.
Allerair leads the way in odor and chemical control. This is typically what the homeowner is most concerned with.
Allerair
also has activated carbon blends that will handle radioactive gases,
toxic gases of military or terrorist use (check out their Sentinel unit
for biological, nuclear and chemical weapon threats), sewage plants and
poultry plants, and museums. If you're going to buy an air purifier, it
only makes sense to purchase one that can control practically anything.
