Are PCO Air Purifiers Better Than HEPA Filters?
By Jeanie Wong Platinum Quality Author
HEPA air purifiers have been on the market for a while, but there have
also been some recent advances made in air purification technologies
as of late. Many air purifier manufacturers are now utilizing Photocatalytic
Oxidation (PCO) technology as a way of removing toxins from the air.
This air purification method may be the most advanced one yet, and some
leading air purifier manufacturers are beginning to add PCO air cleaners
to their product lines.
For years, PCO has been FDA approved for reducing bacteria in meat
processing plants, and it is even used to cleanse pesticides from the
fruits and vegetables we eat. Essentially, PCO filtration can be summed
up as such: An intense light is reflected onto a metal surface which
in turns oxidizes toxins. In chemistry, photocatalysis is defined as
the acceleration of a photoreaction in the presence of a catalyst, and
an example of this would be the oxidation of organic contaminants such
as bacteria and mold using magnetic particles coated with titanium dioxide
nanoparticles, and agitated using a magnetic field that is exposed to
UV light. Therefore, this type of purification technology converts harmful
particulates and toxic gases into safer compounds such as carbon dioxide
and water.
PCO uses broad-spectrum UV light which reacts with a thin film of titanium
dioxide, which, in the presence of water, creates hydroxyl radicals and
super-oxide ions that "burn" VOCs and microorganisms adsorbed
on the catalyst's surface. With that in mind, many consumers may mistake
UV air purification with PCO technology, and rightfully so. However,
while both types of technology are similar in that they harness the oxidation
properties of ultraviolet light, PCO purification systems utilize UV
lamps with additional wavelengths. These additional wavelengths ensure
a quicker reaction rate when it comes the degrading of toxic compounds
that are polluting the air you breathe.
Because PCO technology is an extremely powerful purification method,
PCO units have the ability to eliminate particles as small as 0.001 microns,
including the tiny penetrating particles that can absorb into your lungs
and cause damage (HEPA filters are only able to filter out particles
as small as 0.3 microns). Studies have also shown that in addition to
VOCs, toxic gases, and chemicals, photocatalytic units can also render
gases like carbon monoxide and nitrous oxide harmless - pollutants which
can often escape standard units utilizing HEPA or ionic technology alone.
Those concerned with the possible health effects associated with PCO
will be glad to know that PCO units have been found to be much safer
than ozone and ionization, and they work wonderfully well for those with
asthma, allergies, and multiple chemical sensitivity. Nonetheless, one
should keep in mind that minute levels of ozone are created during the
catalytic free radical generation process, but most PCO purifiers only
produce ozone levels in the 0.01 - 0.04 ppm range (0.05 ppm is the maximum
level allowed by federal law for medical devices).

Air Oasis' AHPCO™
Cell is what makes these air purifiers so
unique, effective, powerful, safe and energy efficient. Unlike HEPA, carbon
and other air cleaners, Air Oasis Air Purifiers don't have to drag
the room's air into the unit to clean the air. Instead, Air Oasis sends "friendly
oxidizers" into
the room to remove air pollution at its source and to sanitize surfaces, leaving
healthy, fresh smelling air.
Air Oasis makes products fabricated and assembled in
the USA that measurably improve the quality of people's lives,
at the right price, combined with corporate financial stability and management
integrity. That combo spells success in anyone's book.
