The Organic Air filter Charcoal Fiber is a line of super efficient, high capacity filters designed to remove particulate matter as well as odors and gases from air. The Organic Air filter line uses charcoal fiber filter elements that pack within the tiny pores on the surface, an amazing capacity to trap gases, particles and organisms. Made from small-pore activated carbon, the charcoal fiber lays out a flattened surface area the size of a regular football field for every one gram of the material. This filtering action is supplemented by the filter design with circumferential and vertical pleats in combination with the inverted nose cone that offers the largest fiber surface area of activated carbon you can get on the market.
