What Is Inside a Pool Filter

Sand filters consist of a large tank, made of fiberglass, concrete or metal, containing a thick bed of special-grade sand, which has a squarish shape. During filtering operation, dirty water from the pool comes in through the filter’s inlet pipe, which leads to the water distribution head inside the tank.

Is pool filter sand toxic?

Rather than containing a whole host of minerals, as beach and play sands do, pool sand primarily consists of crushed silica quartz. The dust from this type of sand is a Class 1A carcinogen that can cause a fatal lung condition called silicosis. This is obviously not something in which you want your children to play.
