Abstract

An air filter that includes a primary filter and a polishing filter. The primary filter comprises a monolith 10 that contains active-particulate. The air-to-be-filtered travels through the primary filter in a path generally parallel to the passageways 12. The polishing filter 36 has first and second major surfaces and also contains active-particulate. The polishing filter is generally arranged such that air travels from the first major surface to the second major surface when passing through it. The inventive filter demonstrates extraordinary performance over the same primary and polishing filters taken individually.
