Abstract
The present invention relates to an air filter housing for supplying air to a space, said air filter housing being configured to be arranged in a ceiling of said space, said housing having a mouth facing downward, said mouth comprising a sealing surface configured to receive a panel type air filter comprising a frame and a filter medium held within said frame, such that a sealing connection between said sealing surface and said frame is achieved, characterized in that said filter housing further comprises at least one resilient member arranged below the sealing surface such that when a panel type air filter is inserted into the mouth, the resilient member will be deformed by the filter frame as the filter passes the resilient member, and resume its original shape once the filter has passed, such that the filter is retained between the sealing surface and the resilient member. The present invention further relates to the use of a filter housing in a cleanroom, and to a method of mounting a panel type air filter in an air filter housing.
