What is a DE pool filter? How does diatomaceous earth work?

A diatomaceous earth pool filter is a very efficient swimming pool product designed to clean your water down to only 3 to 5 microns. This is significantly more filtration than others type of pool filtration can provide. These products look like large canisters that seal shut and can be attached to the pool’s water pipes. Inside the canister, there is a pronged manifold piece that has individual grids attached to each prong.

The way a DE product works is similar to a cartridge filter, with one major difference. First of all, the filter measures how much filtration the water needs by monitoring the pressure inside at any given time. A pressure gauge is an important part of the whole setup, and most of these choices come with one. The manifold inside the tank has several fabric grids, which are very similar to the pleated media in a cartridge filter. When the diatomaceous earth product is set up, DE is poured into the tank and allowed to move around until it settles on the fabric grids. Once there, it can clean out contaminants much more effectively than the grids themselves can. Because of this, the DE is considered the actual media in this type of filter, and not the fabric grids.
