Photocatalysis – How It Works• Photocatalysis reverses photosynthesis: the light-accelerated breakdown of organic

molecules. Photo is Greek for light. A catalyst causes change without being consumed.

• When UVA light energy hits PURETi’s TiO2, it starts a chemical process that turns nearby oxygen and water vapor into two powerful cleaning agents (OH-* and O2

-*)

• OH-* and O2-* convert organic grime into minerals and gas (CO2) and returns to H2O.

• TiO2 is a catalyst, not consumed in the process. Continues to work on the surface.

• The process happens only at the surface, and repeats billions of times to clean the surface and the air that comes in contact with it.

PURETi with Cristal ACTiV – Why It’s Best

10

PURETi with Cristal Activ is a third generation product that lasts longer and cleans faster with less light. Stronger, smaller, less agglomerated nanocrystals

Application directly on the surface produces better results than alternative methods of incorporating TiO2 into products.

Measuring Hygienic Impact -

ATP Test Test Method: PURETi is applied to half of clean ceramic or glass tile. Diluted milk is spread across tile. Tile is exposed to light. ATP (an energy carrying molecule present in all living cells) levels are measured.

Result: Bio Stasis – ATP dropped 50% in 10 minutes on treated slide. After 16 hours, organic load dropped 97% on ATP side; while increasing 34% on untreated side.

The Business Impact of Poor IAQ

“It has now been shown beyond reasonable doubt that poor indoor air quality in buildings can decrease productivity in addition to causing visitors to express dissatisfaction. The size of the effect on most aspects of office work performance appears to be as high as 6-9%, the higher value being obtained in field validation studies.

It is usually more energy-efficient to eliminate sources of pollution than to increase outdoor air supply rates. “

Electrostatic Spray Application

For application to painted

PURETi Base (primer)

Exterior Surface Soiling

• The leading ingredients in grime are:

1. Micro-particles of tire rubber (organic)

2. Soot from the exhaust of cars and factories (organic)

3. Silicates (inorganic sand and soil)

4. Mold, mildew algae (organic)

• High pressure water or chemicals are required to clean most outside surfaces because the organic contaminants form glue-like bonds that are very hard to break.

• PURETi oxidizes (breaks down) the organic particles at the molecular level before they can stick to the surface.

• PURETi does not break down sand, but the sand rinses easily because there is no “glue” to hold it in place.

PURETi - A Powerful Sustainability Story

Treating an area the size

of a football field reverses

the NOx emissions from

over 1,500 cars

Turn Buildings into Trees

• In addition to breaking down organic grime, PURETi exterior solutions also scrub the outdoor air of pollutants.

• Lab studies have shown PURETi treated surfaces can eliminate up to 70% of NOx and NO2 that pass over them.

• NOx is an indirect greenhouse gas and a key ingredient in acid rain and smog.

• One ton of NOx is 25 times more detrimental than a ton of CO2.

52

Meaningful and Marketable Sustainability

• “Sun Washing” with PURETi supports governmental and corporate sustainability missions:• Saves water, chemical, and energy used in pressure washing and window

cleaning

• Increases energy savings by keeping windows cleaner and day lighting more effective

• Can make a facility “NOx Neutral” - effectively zeroing out a negative environmental impact of employees driving to work. • Every car in the lot produces 50 lbs of NOx per year (driving 12,500 miles)

• Every 60,000 square feet treated with PURETi will remove almost a ton of NOx per year, the equivalent of over 500,000 miles driven.

Reduce, Reuse, Recycle, Reverse

PURETi Treated Signs Capture Public Attention

This photocatalytic poem poster was hung from a building in England.

It had the capacity to break down enough NOx to offset the emissions of 30 cars.

This event generated international media coverage, and inquiries from individuals and businesses large and small.

Outdoor Advertising companies are using PURETi to transform their assets into air scrubbers.

This one ad in Spain generated significant media coverage due to its air purifying qualities.

Advertising That’s More Than ‘Hot Air’

Debut of Purifying Eco-Billboard Technology in the U.S.March 23, 2017

Torrance, Calif. (March 23, 2017) – Toyota Mirai trailblazing customers care about the air – their vehicle emits nothing but water vapor. Now, the fuel cell car’s newest campaign is blazing a trail with eco-billboard technology that will help Californians breathe even easier.

The Toyota Mirai eco-billboard campaign, in coordination with Clear Channel Outdoor Americas, will help clear the air from April 3rd through May 28th. Thirty-seven billboards in Los Angeles and San Francisco will create 24,960 square feet of pollution scrubbing surface and reverse the equivalent of 5,285 vehicles worth of nitrogen dioxide (NOx) emissions per month. NOx is a key ingredient in acid rain and smog.
