A Little Light Will Help That...

Glen Finkel, CEO, PuretiGlen Finkel, CEO, PURETi Group says 

"Let's take these guys who know how to use guns, and give them spray guns to help clean those houses. A little light will help that." 

PURETi has been manufacturing photocatalytic surface treatments since 2004.  The company specializes in spray-applied titania products that aim to improve the environment and human health by using the natural power of sunlight to reverse pollution, indoors and out. These solutions are durable, versatile, effective and most importantly low on cost.  

Photocatalysis - the chemical process PURETi products are based on  - is another form of Photosynthesis, the process that plants use to feed themselves.  Photosynthesis has been happening on earth for the last  2 billion years and more. The primary source of energy for photosynthesis to occur of course, is the Sun. Infact, with our fossil fuel deposits fast dwindling, scientists across the globe are working towards using solar energy to directly fuel our activities (without storage or conversion into another form). Such a breakthrough will not only be the ultimate panacea for our addiction for fossil fuel, but also holds the potential of using up all the manmade carbon dioxide that we are, and have been releasing into the atmosphere. 

Photocatalysis is a natural process whereby light energy hits a mineral and triggers a chemical process that results in the breakdown or decomposition of organic matter. 

PURETi trained and certified applicators have completed many projects for schools, architects, artists, commercial property owners, hoteliers and manufacturers. The first PURETi building wide application took place in Los Angeles in 2007 when PURETi treated the exterior of a child development center for the Los Angeles Community College. Columbia University is exploring a campus wide  application in 2018. The potential for this technology is infinite.

  • Mold and mildew in indoor agriculture: Smart cities are continually looking at enhancing local procurement of goods, particular food. However,  indoor growing conditions face a universal problem - mold and mildew. Prolific mold and mildew growth in a greenhouse environment can damage plants, infect soils/other growing mediums, create an unpleasant odor and can lead to stuffiness, eye irritation, skin irritation for people operating inside them. Recently, PURETi helped a marijuana grower with his mold problem. The impact was huge. The application not only got rid of odor issues but also improved community relations. The business increased by 41% that year.
    Even homes, particularly those among affordable housing development projects, face the problem of mold and mildew.  Constrains ability to think clearly.  
  • Barns and chickens: In barns, coops and battery cages, where a  where large number of animals are kept together, the air quality deteriorates, adversely affecting the health of the animals raised. Research has also proved that significant greenhouse gases are emitted through animal agriculture, particularly in the form of odor from manure generation, storage, or land application to farm fields. These odors also affect the quality of human life around the barns and are usually considered a nuisance.   

Mr. Finkel says,"I really want to help those chickens."

  • Offices and Homes: Recent research by Harvard University, focusing on indoor air quality found that the indoor built environment plays a critical role in our overall well-being because of both the amount of time we spend indoors (~90%) and the ability of buildings to positively or negatively influence our health. Closely built structures with reducing ventilation inadvertently lead to a buildup of indoor pollutants. Sick Building Syndrome - a set of symptoms such as eye irritation, headaches, coughing, and chest tightness, is a resultant phenomenon commonly seen among people working in such tight offices.  Mr Finkel is positive that PURETi spray products can significantly contribute to better health of people working in offices.


Mr. Finkel has been passionate about the applications for PURETi since he founded the company. He continues to have big ideas, including training for inner city youth, better indoor gardens in bustling cities, and helping organizations control costs and live in better buildings.
