Active Air Carbon Filters: These filters are filled with virgin activated Australian granular carbon. This type of carbon absorbs VOC's (volatile organic compounds), effectively trapping every single odor molecule that passes through the filter onto the micro-porous carbon surface. These filters are both lightweight and incredibly efficient at eliminating the most potent and unpleasant odors. Each filter is carefully machine packed and comes with a pre-filter included.
Key Features: It has a built-in flange, a carbon bed depth of 1.8 Inches. Both the tops and bases are coated with powder-coated aluminum. Depending on environmental conditions, it has a life expectancy of up to two years.
