The present invention solves a problem of discomfort of ears or skin and hard breathing caused by wearing a mask in the prior art and allows a user to replace the filtering device according to practical demands. The filtering assembly can be worn by a user directly or used together with a mattress, a bed frame, a child carrier, one of an inlet, an outlet and a built-in filtering element of an air treatment apparatus, a window frame, a door frame, or a head mounted accessory, such as a helmet, a hood, a hat or a cap. Therefore, the present invention has a wide range of applications. ## Claims ### Claim 1 A filtering assembly with an air filtering function, the filtering assembly comprising: a covering component for at least partially covering a covered body; at least one opening structure formed on the covering component; and at least one filtering device removably disposed on the covering component and for covering the at least one opening structure. ### Claim 2 (depends on 1) The filtering assembly of claim 1, further comprising at least one positioning structure configured to position the at least one filtering device, the at least one positioning structure being disposed on the covering component and adjacent to the at least one opening structure, and the at least one filtering device being movable relative to the covering component when the at least one filtering device is positioned by the at least one positioning structure. ### Claim 3 (depends on 2) The filtering assembly of claim 2, wherein the at least one positioning structure is an elastic plate structure. ### Claim 4 (depends on 2) The filtering assembly of claim 2, further comprising at least one combining structure configured to be combined with the at least one filtering device, the at least one combining structure being disposed on the at least one positioning structure, and the at least one filtering device being immovable relative to the covering component when the at least one filtering device is combined with the at least one combining structure. ### Claim 5 (depends on 4) The filtering assembly of claim 4, wherein the at least one combining structure is a velcro structure. ### Claim 6 (depends on 1) The filtering assembly of claim 1, further comprising at least one combining structure configured to be combined with the at least one filtering device, the at least one combining structure being disposed on the covering component and adjacent to the at least one opening structure, and the at least one filtering device being immovable relative to the covering component when the at least one filtering device is combined with the at least one combining structure. ### Claim 7 (depends on 6) The filtering assembly of claim 6, wherein the at least one combining structure is a velcro structure. ### Claim 8 (depends on 1) The filtering assembly of claim 1, further comprising at least one light transmissible component, at least one window structure being formed on the covering component, and the at least one light transmissible component being disposed on the covering component and covering the window structure. ### Claim 9 (depends on 1) The filtering assembly of claim 1, further comprising a supporting frame disposed between the covered body and one of the covering component and the filtering device, so as to separate the covered body from the one of the covering component and the filtering component. ### Claim 10 (depends on 1) The filtering assembly of claim 1, further comprising a tightening component disposed on the covering component and configured to tighten the covering component onto the covered body. ### Claim 11 (depends on 1) The filtering assembly of claim 1, further comprising a connecting component disposed on the covering component and configured to connect the covering component to the covered body. ### Claim 12 (depends on 1) The filtering assembly of claim 1, wherein the covered body is a head-and-neck portion of a user, a mattress, a bed frame, a child carrier, at least one of an inlet, an outlet and a built-in filtering element of an air treatment apparatus, a window frame, a door frame, or a head mounted accessory. ### Claim 13 (depends on 1) The filtering assembly of claim 1, where the filtering assembly is a filtering covering. ### Claim 14 A filtering assembly with an air filtering function, the filtering assembly comprising: a covering component for at least partially covering a covered body; at least one opening structure formed on at least one of the covering component and the covered body; and at least one filtering device removably disposed on the at least one of the covering component and the covered body and for covering the at least one opening structure.
