A filters job is to trap all of the fine dust, dirt, sand, particulates and organics that are in your pool water, creating inviting crystal clear water. Your filter won’t purify your water—that’s the job of chlorine. Filter efficiency is measured by its ability to filter out these small particles, measured in microns (1/1000 of a millimeter). For reference, a grain of salt is about 100 microns, and the human eye can see as small as 35 microns without magnification. A sand filter is the least efficient at removing smaller particles, followed by the cartridge filter and the most efficient, a D.E. filter. Sand filters can remove particles as small as 20-50 microns, Cartridge filters 10-20 microns, and D.E. 1-3 microns. Variable speed pumps help to maximize the effectiveness of a filter, as low velocity gives optimum filtration.

Be consistent with your water chemistry so you don’t get calcium build up inside your filter.
Consistently clean/backwash your filter when the filter gauge reaches 8-10 psi over startup.
