Micron disposable filters are meant to last from 2-5 months depending on use and chemicals added. To get maximum filter life with crystal clear water you do not need to use enzymes, brighteners, clarifiers, coagulating agents, or stain & scale preventers. Your filters natural properties will attract oils and scum that go through standard filters, so you can decrease or stop the use of defoamers or other anti-foaming agents.
