Even without square footage noted in the product title, this cartridge is clearly a dimension-driven replacement intended for systems that rely on these exact measurements.\u003c\/p\u003e\u003cp\u003eSome filter replacements are chosen less by broad capacity labels and more by the physical fit required by the housing.
