Summary
AHPCO™, is an Advanced Hydrated
Photocatalytic Oxidation technology. Basically, it is a broad spectrum
high intensity UV light targeted on our patent-pending quad-nano Xtreme™
quad metallic catalyst in a low-level ozone and moist atmosphere. This
creates an advanced oxidation of friendly oxidizers. Unlike ozone, these
oxidizers are safe, but yet aggressive at killing mold, bacteria, viruses
and more. They also effectively neutralize odors and VOCs. Once
they have done their job they revert back to oxygen and hydrogen. AHPCO
technology has been successfully used in water, air, food and laundry
applications.
Development
The UV light and ozone are not new discoveries.
Ozone was first discovered in the late 1800's and used as a water
purifier in Europe. UV light was discovered in the 1930's. Actually,
nature discovered it before; it was called the "sun". The
disinfection qualities of UV light are also not new. Hospitals have
used UV light for decades in operating rooms. Barbers were disinfecting
combs in the 1950's with UV light. What is new is the enhancement
of both these natural, friendly oxidizers and the validation for use
on air, water, food and laundry.
History of Air Systems
In the mid-1980's air purifiers started to make their way into the
residential market. Ozone air systems were widely used in the commercial
restoration business for fire and flood damage to buildings. These
applications utilized corona discharge systems (CD) that use a spark
or electrically charged plates to simulate lightning. This converted
the oxygen (O2) to ozone (O3). The CD method creates very high concentrated
ozone. Plus by using air as the oxygen source, you are receiving 20%
oxygen and 80% nitrogen. The problem with CD systems is with oxygen
conversion you also get a nitrogen conversion, which makes nitric
acid and nitric oxide.
The problem facing the residential
air systems was that the cost of an oxygen generator was so high they
went without one. This, of course, created a CD unit that produced
high concentrated ozone plus low levels of nitric oxide and nitric
acid. The maintenance was a problem due to the corrosive nature of
nitric acid and the high concentration of ozone exceeding the Federal
safety limits of .04 ppm. Ozone readings at the exhaust have exceeded
10 ppm, which is potentially lethal. Air Oasis decided to stay out
of this dangerous market.
In the late 1980's it was discovered
that the lower concentration of ozone could have an effect on odors,
mold and bacteria. Testing this theory, determined that safe, low
levels of ozone could have a significant result with airborne mold,
odors and bacteria. The problem was to create a safe residential air
purifier that could produce safe, low concentrations of ozone that
would not exceed the .04 ppm Federal limits. This was accomplished
in the early 1990's, about the same time as the Federal Government
was going after the ozone residential units. This battle of the Feds
and manufacturers gave ozone a very bad name.
With the technology to build a device
that produces safe, low concentrations of ozone and the ability to
ensure a room would not exceed .04 ppm, it was time to set out to
validate the use of this device on mold, VOC's, odors and bacteria.
Fox TV News was doing a three-part series on indoor air problems and
tested one of the ozone units. The unit they had tested was producing
18 ppm ozone, a lethal amount that drove the camera crew and news
reporter right out of the office. The Fox people then asked if they
could independently test the AHPCO technology. They ran tests supervised
by an independent air specialist and two medical doctors. The series
turned out to be a fantastic infomercial for this technology. The
results couldn't have been better. Fox ran this on their national
news network and their national health news. Popular Science picked
up the story for the magazine and ran it on the Popular Science TV
Show.
In 2003 the AHPCO Cell was developed.
Rhodium was now added as a catalyst and improved hydration compounds
were also added. Plus, a total new target concept was used. A 360
degree cell provided maximum exposure of the catalysts. The bulb was
reworked and a HE/UV Broad Spectrum bulb with a heavy duty filament
and long life coating was developed. This gave the new AHPCO Cell
an unprecedented 3 year, 25,000 hour life. This was a major improvement
over the current standard 8,000-10,000 hour UV bulb life. The most
important improvement was the efficacy, the new cell design created
more hydro peroxides, super oxide ions and ozone levels were .01-.015
ppm or less. Country or forest air is usually around .01-.02 ppm of
ozone. Most people can smell ozone at .01 ppm, and .05 ppm is the
federal safe limit for medical devices. The new cell also produces
hydroxide ions and ozonide ions which broadened the scope of capabilities.
By using a AHPCO™ Cell with
redundant oxidizers our scope of effectiveness is widely broadened.

In March of 2006 our new quad-nano
Xtreme™ catalyst coating was introduced. With this new patent-pending
coating a fifth powerful catalyst metal was added. We also reduced
the particle size of our metals down to a nanosize particle in order
to increase the surface area and therefore increase the kinetic rate
of reaction. The hydrophilic gel was also improved to further hydrate
the coating and react in combination with the metal catalysts (by
donating hydrogen to the ozone) to decompose ozone to form hydroxide
ions, and radicals, as well as hydro peroxides, such as the HO2 radical
and hydrogen peroxides, which are desirable reaction products from
the decomposition of ozone due to their strong oxidizing properties,
which enhances the germicidal effect of UV radiation.
While competitors are using TiO2
alone with no hydrating agents or other less effective catalyst coatings,
Air Oasis is setting the trend for the next generation of air purifiers.
