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

A diatomaceous earth pool filter is a very efficient swimming pool filter designed to filter your water down to only 3 to 5 microns. This is significantly more filtration than any other type of pool filter can provide. These pool filters 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.

similar to a cartridge filter

The way a DE filter 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 the filter at any given time. A pressure gauge is an important part of the whole setup, and most DE pool filters 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 filter 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 filter out contaminants much more effectively than the grids themselves can. Because of this, the DE is considered the actual filter media in this type of filter, and not the fabric grids.

DE Pool Filter Advantages and Disadvantages

Diatomaceous earth filters for swimming pools have several advantages and disadvantages both. Anyone who owns one will tell you that the pros far outweigh the cons, but if you haven’t purchased one yet and you’re trying to make a decision, it’s a good idea to keep everything in mind when it comes to shopping for your new filter.
