    Patent number: 4371386
    Abstract: An improved filter holding device for an air filter that forms a chamber around the periphery of the air filter. A vacuum is created within the chamber to carry any unfiltered air to the upstream side of the filter and thus prevent any air from bypassing the filter and contaminating a clean room.
