It measures 7 inches across and 19-7\/8 inches long, with open ends and a molded gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSizing and fit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCartridge filters only work when the element seals correctly in the housing, which is why diameter, length and end style all matter as much as the square footage. This one is the single cartridge that fills the C500 and CF-50 housings, and the gasket is molded into the end rather than supplied loose, so there is nothing extra to fit and nothing to lose during a change.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnowing when to replace\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean a cartridge and the starting pressure should return close to where it was when the element was new.
