During the winter months in Canada, fine particulate emissions (PM2.5) from indoor fires is the primary cause of air pollution and much of that pollution comes from wood burning fireplaces. This affects the health and well-being of all Canadians, particularly young people, the elderly and those suffering from respiratory diseases. The social cost of air pollution from indoor wood burning is approximately $600 million per year and an estimated that hundreds of Canadians die prematurely each year because of pollution from indoor wood burning. However, wood burning fireplaces don't have to be banned in order to solve this problem.
The HearthCAT can be installed by the homeowner. It is not visible in the fireplace, doesn’t require any maintenance or power and will actually double the amount of heat coming from the fireplace.
Thousands of HearthCATs are currently in use in the United States. It is already required the State of Utah and by many cities in the US for elimination of particulates from wood burning fireplaces. It also eliminates 90% of the CO and VOC’s. Testing and broad implementation of the HearthCAT is also taking place in several European countries.
