DE Pool Filters

DE pool filters are the highest performing filters that you can purchase for your salt water pool. They provide filtration down to a minuscule 5 microns which means they are extremely effective at keeping pool water clean and will produce immaculately clean water. When you combine the filtering power of diatomaceous earth with a salt water pool system you can be sure you are providing the cleanest and healthiest swimming environment for your family, friends or anyone that uses your pool.

A filter that uses diatomaceous earth is ideal for any residential swimming pool because they filter so well with light or moderate use. They can be a bit harder to maintain due to the backwashing if a pool experiences heavy usage like you would see in a community pool. If you consider your pool to fall into the high usage category you will likely want to consider a sand pool filter. Let's take a look at the top rated filters produced by the best pool brands in the world.

Best DE Pool Filters

When looking for the best DE filter there are some features that shouldn't be overlooked. These features will help you keep your pool cleaner throughout the year and make the task of maintaining a DE pool filter a lot easier than compared to other models. An handy pool owner should be able to backwash it on their own but in some cases, a professional may be required. It's important to note that in some municipalities, de filters are not permitted because of their environmental impact so be sure to check with your local by-law regulations.

DE Pool Filters Usage

With average use they need to be backwashed every 4 to 8 weeks or when the pool begins to show signs of cloudiness. If a backwash is required within 3 to 4 weeks then then it could be a sign that the diatomaceous earth needs to be removed and replaced, assuming the pool chemistry is up to par. It can sometimes be difficult to tell when the filter is ready to be backwashed or cleaned but an average diatomaceous earth filter needs to be cleaned once or twice a year.  

The ultra high quality filtration unfortunately means they are not recommended for public or commercial swimming pools because of the high bather load. The filters would need to be cleaned and the diatomaceous earth replaced too often to make it feasible. In many cases the filters fill up with debris and ultimately lose their ability to filter effectively. If this occurs and isn't fixed, the pool can run for days, even weeks providing little or no filtration.
