TL;DR
A sand filter is a pool filtration tank in which pump-driven water percolates down through a bed of graded silica sand that traps debris to roughly 20-40 microns. It is the lowest-maintenance filter type, cleaned by backwashing rather than disassembly, though it wastes some water each cycle and the media should be changed about every five years.
