Abstract
Provided are a space-saving filter that has a plurality of types of air purification capabilities with reduced pressure loss, and a compact air purifier that efficiently exerts a plurality of types of air purification capabilities. Since a body part of a deodorizing filter includes two pieces of deodorizing filter bodies each having the same thickness (hereafter referred to as thickness D) juxtaposed in a plane direction, the body part has the thickness of D. When the deodorizing filter bodies are laminated, the thickness of the body part becomes 2D or more. The body part has a reduced pressure loss and space in a thickness direction compared with a filter in which the deodorizing filter bodies are laminated. The first deodorizing filter body mainly removes aldehyde-based odor components and the second deodorizing filter body mainly removes amine-based odor components. Accordingly, the air purifier including the deodorizing filter has a compact configuration that efficiently exerts the plurality of types of air purification capabilities.
