This Activated Carbon Filter is constructed with a "packed bed" design to give consistent performance, long life (12 to 18 months), and are completely maintenance free. The packed bed of activated carbon design prevents the formation of preferential channels which can allow untreated air through the system. This unique design gives the filter a larger surface area for significantly lowered pressure drops. In other words, it's a double-walled filter packed tight with carbon that allows for a large surface area with no "empty areas" of carbon that would allow air to pass through it untreated.
