Zeolite cartridge filters consist of an aluminum or stainless-steel frame with two outer layers of mesh that contain a zeolite filter medium. Thanks to its unique structure, zeolite is ideal for absorbing vapor and humidity and drying air. Zeolite filters can be regenerated easily in an oven. To achieve the highest levels of efficiency in eliminating odors, these filters should be used in conjunction with an activated carbon filter even in domestic kitchens.
