Another object is to provide a ?ltering unit
which may be readily‘ removed as a unit from
the remainder of ‘they air cleaning or ?ltering
assembly and which may, be readily‘replaced- after
removal and cleaning or other treatment.
Another object is to provide simple means for
holding such a ?lter unit removably in place.
