I have the Jet Model AFS-1000B and it is time to change the prefilter.
Jet gets $30 for a disposable prefilter and Penn State gets $35 for a
washable one. 2 questions, is the Penn state a full 12" or is it 11
1/2" like the Jet? does it perform as well as the disposable filter?
thanks for any and all assistance,
