This creation is about an improved structure of aquarium equipment filter, especially for aquariums, landscaping fish ponds, small culture ponds, or other equivalent applications, including filter cloth, activated carbon filter, filtration The filter is arranged on the outermost layer and is a non-woven fabric of any shape. It is designed to have small pores and high density to filter fine impurities； the filter cloth is coated with activated carbon filter for deodorizing and filtering impurities； activated carbon The inner layer of the filter is coated with a filter made of resin cotton, which has the characteristics of large pores and low density, and is used for filtering large impurities； and the combination of the multi-layer filter material is integrated into the design to make the filter production. The cost is reduced, and the impurities can be stratified and filtered, and the filtering effect is better, thereby further increasing the service life of the filter.本創作係有關於一種水族養殖設備過濾器之改良結構，尤其可用於水族箱、造景觀賞魚池、小型養殖池、或其他等效之應用領域，其包含有過濾布、活性碳過濾片、過濾網；過濾布設於最外層，係任意形狀的不織布，設計為氣孔小，密度大的態樣，用以過濾微小雜質；過濾布內包覆可除臭及過濾雜質的活性碳過濾片；活性碳過濾片內層則包覆由樹脂綿製成的過濾網，該過濾網具氣孔大、密度小的特性，用以過濾大型雜質；透過多層過濾材質結合為一體成型的設計，使過濾器的生產成本降低，並可分層過濾雜質，過濾效果更佳，進而還可提高過濾器的使用壽命。
