Scientific's PureWave™ process removes
contamination from your air as well as your
surfaces by combining two very powerful
purifying technologies - photoplasma and
photochemistry. These methods for purification
have been studied verified and documented
by the scientific community. Bottom line
is this technology really works!
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 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. We 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 Ð
the breakdown and formation of new hydroxyl
radicals results in the continual decay
of organic material.
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.
