PROBLEM TO BE SOLVED: To provide a dust removal/deodorization filter apparatus which includes a dust removal filter and a deodorization filter and enables these filters to be separately replaced while keeping the dust removal/deodorization performance of the dust removal/deodorization filter apparatus.SOLUTION: A dust removal filter 2 and a deodorization filter 3 are incorporated detachably in a frame body 1 and these filters 2, 3 can be separately replaced. The dust removal filter 2 is pressed to the back surface side of the frame body 1 by a cover 4 fitted turnably to the frame body 1 and an airtight material 21 and a flanged part 20 of the deodorization filter 3 are held between the peripheral part of the back surface of the dust removal filter 2 and a stepped face 10 arranged on the inner peripheral surface of the frame body 1 to surely seal the space between both filters 2 and 3, so that the dust removal/deodorization performance equal to that of the conventional filter apparatus can be obtained.COPYRIGHT: (C)2012,JPO&INPIT【課題】除塵脱臭フィルタ装置の除塵脱臭性能を確保しながら、その除塵フィルタと脱臭フィルタをそれぞれ単独で交換可能とする。【解決手段】枠体1に除塵フィルタ2と脱臭フィルタ3を着脱可能に組み込んで、各フィルタ2、3をそれぞれ単独で交換可能とするとともに、枠体1に回動可能に取り付けた蓋4で除塵フィルタ2を枠体1の後面側へ押圧して、除塵フィルタ2の後面の周縁部と枠体1の内周面に設けた段差面10とで気密材21と脱臭フィルタ3の鍔部20を挟み付けることにより、両フィルタ2、3間を確実にシールして、従来のものと同等の除塵脱臭性能が得られるようにしたのである。【選択図】図2
