In the filing’s own words

A ceiling type air cleaner comprises a housing comprising an opening arranged on a lower side of the housing; a filter arranged on a side of the opening; and an edge plate arranged on the lower side of the housing to support the filter and comprising a locking portion configured to lock the filter to the housing and unlock the filter from the housing. The locking portion comprises a space portion forming a space inside the edge plate; a sliding member configured to slide along the space portion; a fitting member configured to allow the sliding member to be fixed to or released from the space portion so as to allow the sliding member to slide; and a link configured to rotate according to the sliding of the sliding member so as to lock the filter to the housing or unlock the filter from the housing.
