Fitting one or two new elements alongside older ones pushes most of the flow through the new cartridges, so they load up quickly and the set never performs like a clean filter. Changing all four together is the way to get a full season out of them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCleaning versus replacing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePleated cartridges are meant to be rinsed and reused several times.
