Running two stages in series means the first cartridge does the bulk of the work and the second catches any breakthrough, extending the time between full resin changes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e dual canister housing with 1\/4in push-connect fittings.
