What is a DE Filter and How Does It 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 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 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 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.

Advantages and Disadvantages of DE Filters

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.

Some advantages of DE filters include:

  • They’re very cost-effective in the long run. Replacement grids and DE don’t cost a lot, so over time, they can be very affordable.
  • They can get your water cleaner than other filters. They’re currently the strongest and most powerful type of pool filtration on the market.
  • They’re easy to clean. You can usually take care of the whole cleaning and recharging process in 30-45 minutes.
  • They come with everything you need to get started. This includes the pressure gauge and starter grids.

Some disadvantages of DE filters include:

  • They need to be cleaned every month. They do require more frequent full cleanings and recharging than other types of filters do. This is part of what helps keep them functioning for so much longer than other filters.
  • They can be very expensive at startup. These are costly filter units when you first install them. However, the savings over time can more than make up for it.
  • Repairs can be costly in some instances. For some filters, replacement pieces and repairs when something breaks can be a little expensive. This doesn’t include the cost of regular grid replacements, however.
