Fiberglass is a plastic impregnated with small glass fibers for reinforcement, with the feature of lightweight, preservative, wear-resistant and nondeformable. It is an ideal material for the most sand filters. The stainless steel also works the same, furthermore, it is a harder material. The difference between them is that the pressure, fiberglass sand filter is 0.6 Mpa, Stainless steel filter is above 1 Mpa. The fiberglass one can meet the needs of most swimming pools and if you need a high specification one, stainless steel fiber is a better choice.
The Mount of the fiber
There are Top-mount Sand filter and Side-mount sand fiber. The top-mount sand filter is cheaper than the side mount and takes less space. Side-mounted sand filters make it easier to change the sand, no need to move the internal pipes, just open the top cover to replace the sand, but take up more space. If space is limited, a top-mount in-ground sand filter is a better choice.
