Scientists tackle indoor air pollution

People on average spend nearly 90% of their time indoors and, especially in the cold winter months in Canada, this statistic can be even higher. With all that time spent indoors, filtering out pollutants from indoor air is very important for the health of Canadians.

Researchers from the College of Engineering at the University of Saskatchewan (USask) have been developing a catalyst for a new type of air purifying technique that would clean air at room temperature.

“Ozone is one of the strongest purifying agents that has been used in the water treatment industry for a long time. In our research, we use ozone and an effective catalyst to purify indoor air from Volatile Organic Compounds or VOCs,” explained PhD student Mehraneh Ghavami.

Ghavami and co-researcher Dr. Jafar Soltan used the HXMA beamline at the Canadian Light Source (CLS) at USask to discover which types of metal catalysts would work best for eliminating pollutants out of the air and recently published their findings.

Their air purifying system uses ozone gas and a catalyst to remove indoor air pollutants and turn them into carbon dioxide and water.
