How TiO2 UV Photocatalytic Oxidation (PCO) Works
Photocatalytic oxidation (PCO) is
achieved when you combine UV light rays with a TiO2 coated filter. TiO2 refers
to Titanium Oxide. This process creates hydroxyl radicals and super-oxide
ions, which are highly reactive electrons.
These highly reactive electrons
aggressively combine with other elements in the air, such as bacteria and
VOCs. VOC is an acronym for Volatile Organic Compounds, which include harmful
pollutants such as formaldehyde, ammonia and many other common contaminates
released by building materials and household cleaners generally found in the
Once bound together, the chemical
reaction takes place between the super-charged ion and the pollutant,
effectively "oxidizing" (or burning) the pollutant. This breaks the pollutant
down into harmless carbon dioxide and water molecules, making the air more
Catalytic Oxidation (PCO) is an advanced process by which volatile organic
compounds (VOCs), bacteria, mold and fungus is destroyed by incorporating
photon and ultraviolet (UV) energy activating a catalyst creating photo
catalytic oxidation (PCO). PCO is produced by the air being exposed to photon
light and passing through a catalyst comprised of specific nano-sized mineral
compounds. After exposure and upon entering an area, three specific free
radicals are released which destroys the bioaerosols (bacteria, molds, and
fungus). During the process, hydrogen peroxide, hydroxyl radicals, and
hydroxides attach themselves to specific organisms and kill them.
of producing PCO is directly linked to the efficacy of the results. The
advantage of this specific technology is a higher yield of free radicals which
occurs due to the exposure of catalytic compounds. If low levels of PCO are
introduced into a room, this would be effective in removing odors caused by
organic elements, smoke, fungi, and bacteria. When the levels of PCO are
increased, it would only produce a greater benefit. This would be appropriate
in such places as homes with smoke damage or high levels of microbial
contamination. This would also be useful in automobiles with tobacco or musty
introduction of PCO into an environment would be to destroy the microbial
contaminants. Another aspect of using PCO is that it is successful at killing
pathogens organisms. There are various types of microbial spores that can be
treated, but it is also an advantage that advancement in this technology now
makes it possible to use PCO as a defense against specific organisms that may
threaten the general population when used by radical organizations.
Technology can be used with-out causing any disruptions. Free standing units
are not very noticeable. They can sit in a bookshelf or on a table. They can
be placed into the air duct system for even distribution in your airspace. PCO is used every day to kill microbial contaminants and keep your environment
healthy. People today want to be safe where they work and live. PCO
technology helps to confirm their concerns.

Principle of Photo-Catalytic Oxidation
Photocatalytic Oxidation (UV PCO TiO2) Studies
from the University of Colorado and the National
Renewable Energy Laboratory in Colorado conducted an experiment
testing the effectiveness of photocatalytic oxidation against harmful VOCs
(volatile organic compounds such as formaldehyde and other known
carcinogens). They found that destruction of these
contaminates was nearly 100%.
Scientists working on behalf of the
U.S. Department of Energy found that photocatalytic
oxidation air purification may be beneficial for the large-scale treatment
of air in occupied buildings, while conserving energy costs. This is due to
the fact that this technology destroyed VOC chemicals at a
significant rate, even at high air flow rates. Their study indicated that
photocatalytic oxidation could provide as much VOC removal by itself as
compared to the expensive process of introducing outdoor air into the indoor
environment, drastically reducing the need to channel outdoor air inside.
In another study commissioned by
the U.S. Department of Energy, scientists found that
photocatalytic oxidation converted more than 95% of harmful
VOC chemicals to harmless carbon dioxide and water molecules.

Air Oasis Makes
Scientifically Advanced Products that Clean Up Today's

The Air Oasis uses an
AHPCO Cell, (Advanced
Oxidation technology). The cell consists of a special broad
spectrum high intensity ultraviolet (UV) lamp. The
improved UV lamp cell technology Air Oasis has achieved
an astonishing 25,000 hour (3 year) life span instead of
the usual 1 year.
Many UV lamps maintain 65% of their output at 9,000
hours, whereas ours will maintain up to 80% of their
output at 16,000 hours.
The UV light is targeted on a hydrated TiO2 metallic
catalyst. With this catalyst the ozone created by the UV
lamp is converted into friendly, safe and aggressive
oxidizers that revert back to oxygen and hydrogen. The
AHPCO Cell produces minimum ozone levels well below the
amount considered safe by the EPA. AHPCO Cell technology
has been successfully tested and approved to combat a
variety of indoor air quality concerns. Note: Danger /

How the Air Oasis Air Purifier Air Cleaner
How It Works:
Without high-powered fans or thick filters, this non filtration system uses a
lamp that destroys germs with UV light. That light is reflected with the AHPCO
catalyst, which produces catalytic molecules, which then, in turn, seek out
and destroy carbon-based molecules. This powerful small air purifier cleans
the air quickly, efficiently, and without using too much energy. Air Oasis now
has Bi-Polar technology to further enhance the effectiveness of our

contains six rare catalyst metals. Air Oasis' also
incorporates nano size particles and special hydrating
agents to increase the kinetic rate of reaction providing

In addition to using Bi-Polar Ionization and an AHPCO catalyst, the Air Oasis Sanitizers also includes LongLife technology. Because of this
specialty coating on our UVC lamps, the output of our lamps is far
higher than the industry standard. Many lamps maintain 65% of their
output at 9,000 hours, whereas ours will maintain up to 80% of their
output at 16,000 hours.
Warning about other PCO Air Purifiers
There are many air purifiers on the market that use PCO (Photo Catalytic
Oxidation) technology. If not used properly PCO technology will do little to
purify your air. In fact it can cause an increase in harmful contamination.
Researchers have found with many PCO air purifiers that incomplete
decomposition of the VOCs in the air stream there is a net production of
formaldehyde, acetaldehyde, formic acid and acetic acid. Of particular concern
was that the outlet concentrations of formaldehyde and acetaldehyde were 3.4
and 4.6 times the inlet concentrations, respectively. Both formaldehyde and
acetaldehyde are recognized as important indoor toxicants. Formaldehyde is
classified as a human carcinogen. Governmental guidelines suggest keeping
indoor concentrations of formaldehyde and acetaldehyde at very low levels.
Many brands of air purifiers are beginning to use cheap imitations of PCO
technology in their product. Most use cheap titanium dioxide (the basic white
pigment in paint) as their catalyst. They then combine this with a cheap
foreign UV lamp and call it a PCO air purifier. These air purifiers will not
usually provide any University studies to validate their claims.
Air Oasis developed a proprietary
metal nano catalyst that
is far superior to any cheap imitations on the market. Their UV lamps use a
proprietary long life coating to more than double their life over competitor
lamps. Preliminary results from West Texas A&M University show huge reductions
in formaldehyde and other VOCs. Rapid reductions in odors were also observed.
