Sand Pool FiltersSand Filters are the most popular filters used in swimming pool filtration. They use a specifically graded #20 silica sand to trap particles (down to 20-100 microns) as the water runs through the filter. These particles build up in the sand and eventually have to be “backwashed”. Backwashing is the process of running water through the filter backwards clearing out all of the filtrated particles through an line that leaves the filter and pool. This usually involves turning or pulling on a filter valve.
