I have a vintage Portapower that i use and am happy with. I sometimes use the *N* bag, and have a stockpile. Seems some of the *N* bags i have are lined, for better filtration, I imagine. Some arent. I thought all the type *E* bags were double layered also. I just opened a new pack, and these are single layer. Why?
