Abstract
A procedure for testing the efficiency of filtration media is disclosed. The procedure employs uniform microspheres in a latex which are suspended in an airstream and directed through the medium to be tested. The liquid in the airstream is removed from the airstream after passing through the medium, and a portion of the airstream is directed to a particle counter to count the particles in the airstream. By comparing the particles counted with and without the medium in the airstream, the efficiency of the medium can be determined.
