This reduces mold indoors, creating healthier air indoors. The tiles also "clean the air", absorbing nicotine and pet smells and VOC's from surrounding furniture and building materials.
The tile can be used everywhere: bathrooms, bedrooms, closets. Its only limitation is that it cannot be used in areas that get completely wet, like a shower. Distributed by Stone Source here in NYC.
