Home / Ventilation / Ducts/Accessories Product Description The Activated Carbon Filters are constructed with a "packed bed" design to give consistent performance, long life (12 to 18 months), and are completely maintenance free. The packed bed containing 4 pounds of activated carbon prevents the formation of preferential channels which can allow untreated air through the system. This unique design gives PureFlow Filters a larger surface area for significantly lowered pressure drops.
