A sand filter can capture particles in the 20-40 micron range and it becomes increasingly more efficient as it continues to filter on a regular basis. As with the D.E. filter, your sand filter will have to be backwashed when the gauge shows 8-10 psi over the starting value. Sand filters have the reputation of being the lowest maintenance of all the different pool filter types as it takes roughly 5 years before your first time replacing the sand.
