  • Publication number: 20140224127
    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.

  • Patent number: 7615106
    Abstract: A control device repeats first air volume control and second air volume control for a predetermined number of times irrespective of a control state at that time while forcedly driving an ion generator, when a bacteria elimination shower switch is turned on. In the first air volume control, a sirocco fan generates an air flow having a predetermined air volume. In the second air volume control, the sirocco fan generates an air flow having an air volume smaller than the predetermined air volume. Therefore, a bacteria elimination effect is enhanced in an air conditioning apparatus.
