How Pool Filter Sand Works; Pool filter sand works as a natural filter, trapping dirt and debris that pass through your pool's filtration system. The sand particles are typically 0.45 to 0.55 mm in size, allowing them to capture particles as small as 20 microns. This includes things like dust, dirt, and even some types of bacteria.
