Hey everybody, I can't find the round foam pre motor filters for my 1983 kenmore canister. It is the kind with the hose in front. I know the tristar filters would fit in diameter, but would they be ok on the motor since thay are thicker and heavier than the original? OR Does anybody know where I can find the kenmore filters? Sorry to have to start a thread for such a small question. Have a blessed day everyone!!
