Problem to be solved: to provide an improved structure of the aquatic life support filter which can improve the air in the indoor space and enjoy life with aquatic organisms and enjoy the vegetable garden.The improved structure of the aquatic life support filter 1 includes a filter cloth 11, an activated carbon filtration sheet 12, and a filtration mesh 13, and the filter cloth 11 is a pore having a small pore size and at least one nonwoven fabric of a large density, and the foreign substance of a small volume is filtered The activated carbon filtration sheet 12 is comprised of an activated carbon material that covers the interior of the filter cloth 11 and allows at least one deodorization and further foreign matter filtration, and the filtration mesh 13 covers the inner layer of the activated carbon filtration sheet AndIn addition, it is made up of at least one resin cotton and has a large pore size and smaller density than the filter cloth 11, and is used for filtering a relatively large foreign matter.Diagram【課題】屋内空間の空気を改善し、水生生物との生活を楽しむことができると同時に家庭菜園を楽しむことも可能な水生生物飼育フィルタの改良構造を提供する。【解決手段】水生生物飼育フィルタ1の改良構造は、濾過布11と、活性炭濾過シート12と、濾過メッシュ13とを含み、濾過布11は、気孔が小さく大密度の少なくとも一層の不織布であって、微小体積の異物を濾過するために用いられ、活性炭濾過シート12は、濾過布11の内側を覆うとともに、少なくとも一層の除臭及び更なる異物濾過を可能とする活性炭材質からなり、濾過メッシュ13は、活性炭濾過シート12の内層を覆うとともに、少なくとも一層の樹脂綿からなり、且つ、濾過布11よりも気孔が大きく低密度であって、比較的大きな異物を濾過するために用いられる。【選択図】図1
