PROBLEM TO BE SOLVED: To provide an air cleaner that can reduce the risk of damaging works of art by suction air and exhaust air while continuously removing microorganisms and harmful gas in a room over a wide range when removing harmful gas generated from an interior material and the like from a space in the closed space where the works of art are displayed.SOLUTION: A dust filter, a gas removal filter, and an antibacterial filter are laminated (a laminated filter 7), and integrated so as to achieve reduction in size of an air cleaner body 4, and by suppressing an amount of air to be blown to a predetermined level, an indoor environmental condition is kept constant so as to prevent works of art from being damaged. Also, by performing air circulation in a sealed space by the air cleaner, it is possible to suppress accumulation of microorganisms, particulate materials, and harmful gas on the works of art.COPYRIGHT: (C)2015,JPO&INPIT【課題】美術品を展示する閉め切られた空間内において、内装材などから発生した有害ガスを空間内から除去する際、広範囲に渡って継続的に室内の微生物や有害ガスを除去しつつ、吸引風、排気風によって美術品を傷つけるリスクを抑えた空気清浄機を提案する。【解決手段】除塵フィルタ、ガス除去フィルタ、抗菌フィルタを積層7し、一体化することによって、空気清浄機本体4のコンパクト化を実現し、さらに、送風量を一定量に抑えることで、室内環境条件を一定に保って美術品を傷つけてしまうことを防ぐ。また、該空気清浄機によって、密閉空間内の空気循環を行うことによって、美術品への微生物、粒子状物質、有害ガスの滞留を抑制することが可能となる。【選択図】図2
