| If you thought air pollution was just an outdoor problem, think again. The particles you see in a beam of afternoon sunlight streaming through the window represent only 1% of the airborne contaminants in your indoor air. Not only that, but every building contains a certain amount of unhealthy gasses from many sources - building materials, the earth under the building, heating and cooling systems, and even people, who exhale carbon dioxide. We offer solutions. |
