Photocatalyst and Negative Ion Bulb was scattered like wildfire passing to every ears of Filipinos, the innovation has been already successful, whereas someone spent time to research it and post it without even using and feel the benefits of it. I am a user a the said bulb and it really helps me a lot, when I got the Photocatalyst and Negative Ion Bulb and used it in my tiny shop, drastic changes has been made.
Researched by an unknown blogger was published in a blog, readers be aware because it was really misleading, he only qoutes Carl Koval's saying about the Tio2 , without knowing that Carl is also an inventor of improve photocatalyst application.

Reading upon the line,
"..Says Koval, “When illuminated TiO2
is used to decompose organic compounds, a
large number of intermediate compounds are
usually formed. In some cases, these intermediate compounds can be more hazardous
than the compound being decomposed.” For
example, he says, the breakdown of TCE
yields trichloroacetic acid (a substance almost
as toxic as TCE) and, in the gaseous phase,
p h o s g e n e ( a c h emi c a l w a r f a r e a g e n t ) .
However, he says, this doesn’t mean that all
applications using TiO2
would be dangerous.
“In situations where this type of process was
being proposed for outdoor use, I see no
problems with it, because similar things occur
naturally in the atmosphere, and it would be
unlikely that concentrations of the hazardous
c h emi c a l w o u l d r e a c h t o x i c l e v e l s . . . .
However, [in an indoor setting] who knows
what would be formed if TiO2
photocatalysis were used to decompose plasticizers, bacteria,
and so on, and what the health effects might
be from inhaling such compounds?”
Certainly there is cause for caution, agrees
Anderson. “But given time and control over
the process,” he adds, “these daughter products do break down into environmentally
benign substances, a process which can be
monitored using a gas chromatograph.” And,
says Blake, “All oxidization processes have
the potential to produce partial oxidization
products. It comes down to a question of the
fraction of the target compounds that are
converted to the intermediate products and
how much of those produced are released
into the air or water. The amount released
will be a function of the efficiency of the
photocatalytic device and the way it is constructed and operated.”
All that being said, in the realm of envir o nme n t a l c l e a n u p t e c h n o l o g y i s T iO2
indeed the white knight riding to the rescue
or something less? Says Blake, “There is no
single technology that can address the very
wide range of contamination problems in
the environment. Most workers in the field
recognize that the photocatalytic chemistryof TiO2 has pluses and minuses that make it
attractive for some applications and not for
o the r s . The pho t o c a t a l y t i c chemi s t r y o f
TiO2
is very intriguing. It works in water or
air, it uses light instead of heat, and it is
such a simple concept. Engineering it with
the right balance of economics and performance is the challenge.”

That article was written 10 years ago, so what do you think has happened after 10 years? Does the development of Photocatalyst and Negative Ion Bulb has been changed? Those articles is just a speculation that time, the reason why it is written with a question mark (see Title: Titanium Dioxide:
Environmental White Knight?, means that it was not proven at the time, but after ICC (Import Commodity Clearance) has certified the product of Goodfaith, no question ask get your GoodLights, come and get one used it and enjoy the benefits of inhaling clean air.a
