Biozone Scientific's
PureWave™ ionic air purifiers remove contaminants from air and
surfaces by combining two very powerful purifying technologies -
photoplasma and photochemistry. While these methodologies have been
well studied and documented by the scientific community, the synergy
of their interaction produces a unique and a superlative way of
cleaning air and surfaces of contaminants like allergens,
noxious odors, toxic mold, VOCs and tobacco smoke from indoor
air,.
Photochemistry is the
chemical reaction or change in material caused by exposure to light
energy. The process typically requires the use of photons in the
ultraviolet spectral range. Ultraviolet light in this range is
useful for disinfection purposes. When a strong enough ultraviolet
light is present, it becomes useful in the destruction of
contaminating organic compounds. Almost all indoor contaminants are
organic, such as toxic volatile organic compounds, dust particles
like dander, hair, dust mite feces, etc., and biological
contaminants like bacteria, viruses, and fungi. Photochemistry can
break down these harmful organic molecules.Ultraviolet light with
enough energy such as in the 100-280 nanometer wavelength range can
also break down the electron bonds of an organic molecule.
Ultraviolet light
wavelengths in the 100-280 nanometer bandwidth not only break down
electron bonding of an organic molecule, but also initiate the
formation of a cold gas plasma. Biozone ionic air purifiers excite
gases by the energy from ultraviolet light waves and create a highly
energized gaseous state. The plasma, or highly energized gaseous
state, is aggressive and highly reactive and contains excited atoms
and molecules, ionized gases, radicals, and free electrons. It can
destroy just about all organic contaminants. The destruction
mechanism primarily involves the photodissociation of molecular
oxygen leading to the formation of highly oxidizing species, such as
atomic oxygen, molecular singlet oxygen and ozone.
These reactive species
interact with contaminants converting most to carbon dioxide and
water. The UV light also creates electron ejection of organic
molecules that produces additional free radical creation. The
radicals react with oxygen producing hydroperoxide ions, with the
whole process creating a chain reaction with organic compounds
triggering further oxidation. When additional hydrogen is added as
in the form of water or water vapor (humidity), the highly oxidative
species hydroxyl radicals is created. These radical ions are stable
and are very destructive to organic contaminants because they steal
hydrogen atoms from the organic materials, leaving decaying carbon
ions. The theft of hydrogen from organic molecules forms even
stronger hydroxyl radical bonds with even higher oxidation
potential. This entire process turns into a chain reaction -- the
breakdown and formation of new hydroxyl radicals results in the
continual decay of organic material.
The ejecting of electrons
from a molecule by high energy ultraviolet light is called the
photoelectric effect, and it can be further enhanced by irradiating
what is called a "photoelectron emitting member" to eject more
electrons. Such a photoelectron emitting member is contained in
Biozone Air Purifiers. The photoelectrons ejected are used to charge
fine particles in a gas which are then removed from the air stream
as they attach to oppositely charged surfaces. This electrically
charging of dust and other particulates can remove particles as
small as .001 micron. It should be noted that each of the electron
ejections can cause multiple ionization events. For example, in the
photoelectric effect, the photon undergoes only one interaction, yet
thousands of ionizations can be caused by the resultant electron and
its products.
The PureWave™ process
combining photochemistry and photoplasma has been reported to be
extremely potent in removing contaminants from the air and surfaces.
There is scientific evidence that surfaces can be decontaminated 100
- 2000 times faster than with other purifying methods.
