Air purifier studies conducted by
West Texas A&M university at BSA Hospital confirm that our air
purifier / sanitizer technology not only purifies your air, but
sanitizes surfaces. This study measured reductions in methicillin
resistant Staphylococcus aureus, MRSA on surfaces.
This study also measured reductions in other
microbes and fungus. There was a 75% reduction in microbes and
fungus in only 8 hours of use. Other studies show an almost
complete eradication over longer periods of exposure to our air
purifiers.. |
Studies have also proven effective
treatment on the concentration of indoor aeroallergern
concentration. Current ongoing studies are aimed at proving
reductions in VOC and odors. These tests will be conducted against
formaldehyde, hydrogen sulfide, carbon disulfide and more.

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).
