Abstract: An air purification member is provided that can reduce the generation of unpleasant odor or the occurrence of air contamination without necessitating frequent cleaning or replacement. The air purification member can be part of an air purification unit or an air conditioning apparatus. A first photocatalytic filter of an air purifier is a filter for purifying air that contains particulates containing viruses or microbes, and is provided with a photocatalytic filter and a photocatalytic apatite. The photocatalytic filter collects the particulates. The photocatalytic apatite removes viruses or microbes that are contained in the particulates collected by the photocatalytic filter.

Abstract: There is provided a stain-proofing coating composition being capable of forming a uniform stain-proofing surface by blending a hydrophilic material in a low concentration irrespective of kind of a polymer for a coating. The stain-proofing coating composition comprises the hydrophilic material (A), the hydrophobic polymer (B) for a coating, the organic solvent (C) for the hydrophobic polymer for a coating and the other organic solvent (D); the other organic solvent (D) being a high boiling point organic solvent having a boiling point higher than that of the organic solvent (C) for the hydrophobic polymer for a coating by 5° C. or more, and a ratio of the hydrophilic material (A) to the hydrophobic polymer (B) being from 1/99 to 50/50 (% by mass ratio).

Abstract: An air conditioner that can decompose and remove bacteria, viruses and the like, which are sources of odor, with efficiency is provided. The air conditioner includes a resin part and an apatite having a photocatalytic function. The resin part forms an air distribution path. The apatite is disposed on at least part of the resin part.

Abstract: A cleaning treatment material has a mixture of a photosemiconductor catalyst and an apatite, which has a photocatalytic function. Secondary particles of the photosemiconductor catalyst are 0.1 to 1.0 ?m in diameter. In addition, secondary particles of the apatite are 1 to 10 ?m in diameter.

Abstract: The heat exchanging unit includes an indoor air exhaust passageway, an outdoor air supply passageway, a heat exchange element, and a first air cleaning member. The indoor air exhaust passageway exhausts indoor air to an outdoor space as exhaust air. The outdoor air supply passageway supplies outdoor air to an indoor space as supply air. The heat exchange element exchanges at least a sensible heat of the sensible heat and a latent heat between the exhaust air and the supply air. The heat exchange element communicates with the indoor air exhaust passageway and the outdoor air supply passageway. The first air cleaning member is provided at a supply airflow upstream side of the heat exchange element. The first air cleaning member has an apatite that has a photocatalytic function.
