摘要： An internal support for an air filter includes a helical member which is shaped and dimensioned to fit against the inside surface of the air filter to provide structural support which prevents the air filter from inwardly collapsing. In another embodiment of the invention, a plurality of support rings are installed in spaced apart parallel relationship inside the air filter.
