My new Volvo has a Cartridge type filter. I wanted to use a Pureone filter, Purolater only make the cartridge in it's regular premium filter. My concern was the back flow preventer valve. I E mailed Puralotor on the valve and they responded that cartridge type filters fit in a canister and do not have a backflow valve.
Does anyone know how these cartridge filters work. Would the cannister have it's own valve?
