Air purifier studies conducted by West Texas
A&M university at BSA Hospital confirm that Air Oasis 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).

Concerns about indoor air quality
(IAQ) have increased since the 1970’s when people started doing
a better job of sealing their homes and offices to conserve electricity.
Sealing buildings better only reduces the amount of fresh outside air
from coming into buildings and contributes to the buildup of indoor air
contaminants.
Complaints about IAQ range from simple complaints, such as the air smelling
odd, to more complex complaints where poor air quality results in illness
and absence in school. Identifying a single reason for these complaints
is difficult due to the number and variety of possible sources, causes,
and individual sensitivities.
Indoor air pollutants fall into three main categories:
Particulates - Over 99% of particulate matter is invisible to the naked eye and easily
infiltrates the lungs. On average, every cubic foot of untreated indoor
air contains 20 million particles.
|
Microbes - Includes three major types of organisms: bacteria, protozoa, and fungi/mold.
Most of these contaminants rely on a humid and moist environment for growth
& survival. Some molds produce certain chemicals, such as mycotoxins
and Volatile Organic Compounds (VOCs).
Gases
& Odors - Indoor gases, such as benzene, formaldehyde, and
hydrogen sulfide, are released into the air from furniture, carpets, hair
sprays, cleaning chemicals, insulation, and pesticides. Gases include
VOCs which evaporate into the air easily. Odors are often composed of
VOCs or other gases.
