Air Purifiers that use ozone
have come under fire of late.
The
problem stems from the fact that some manufacturers of ozone generators
first advertised and sold the ozone systems as “In the Home
Air Cleaners”.
Typically an ozone generator is a machine that simulates lightning
by a corona electric arc or spark. Thus the name "Corona Discharge
System". Strong ozone occurs through this conversion of oxygen
to ozone. These units well exceed the limit of .05ppm which is the
current limit the Federal Government has placed home air purifiers.
Corona Discharge was never meant to be used in the vicinity of people;
this form of ozone air cleaner is to be used strictly in unoccupied
areas of very high contamination. The companies that sold
these units as air purifiers succeeded in creating a skewed public
perception and in giving ozone a very bad name.
To improve this situation other manufacturers have sought out different
means of utilizing ozone as an air purifier
mainly by way of a UV-C ozone lamp. Although it brings the level
of ozone produced way down, the method remains highly unregulated
and will still manufacture ozone above the federal limit of .05ppm
in some cases. This continued inability to harness ozone gas recently
brought the ozone air purification industry under fire again.
In September of 2007, California approved a ban on all Air Cleaner
Brands that
produce ozone above the Federal limit. California Assembly Bill
2276 (2006, Pavley), signed by Governor Schwarzenegger in September
2006, directs the Air Resource Board (ARB) to develop and adopt
a regulation to limit the ozone emitted from indoor air cleaning
devices in order to protect public health. The bill requires the
ARB to adopt the regulation by December 31, 2008.
These indiscretions and oversteps in the ozone air purification
industry have overshadowed and seemed to be on route to cripple
research on other methods of ozone cleaning technologies
that have proved to be safe and more effective.
AHPCO(advanced hydrated photo catalytic oxidation) is one such technology. This process exposes a metallic
photocatalyst to a UV-C Ozone lamp in a moist atmosphere.
The result is a reaction
that converts the ozone into hydyoxl ions and hydoperoxide ions
to name a couple. These "AHPCO" chambers succeed in utilizing
the powerful oxidizing qualities of ozone to purge the air of impurities
while maintaining a level of only .01 to .02ppm. Well under the
current Federal limit of .05ppm. What's more is the conversion of
O3 into hydroxls, hydroperoxides, and super oxide ions which are
individually each a more powerful air cleaner than ozone. Combined
they are a massive force in the fight against Indoor Air Pollution.
Time will tell whether or not this important technology will get
"lumped in" with the other ozone type air purifiers that
are being targeted by the EPA of California.
The company at the forefront of bringing this technology
to the marketplace is "Air Oasis". Their mark is a unique
"nano-catalyst" which is a propiatery blend of metals
and nanotechnology. The catalyst is said to give the the air cleaning
oxidizers and ions an
unprecedented “shelf-life”.
A proven way to harness the capacity
of ozone to provide a safe healthy environment to breathe in.
