What is a D.E. Pool Filter?

If you are a pool owner, you are probably familiar with various pool filters available in the market. Among them, D.E. (Diatomaceous Earth) filters stand out due to their unparalleled ability to remove even the smallest particles from the water, providing crystal-clear and clean water for the swimmers.

In this article, we will explore everything you need to know about D.E. pool filters, including their function, benefits, maintenance, and installation.

How does a D.E. pool filter work?

A D.E. filter functions by using a fine powder made of fossilized prehistoric organisms (diatoms) that form a filter media that traps and removes impurities from the water. Unlike cartridge and sand filters that work by trapping debris on its surface, a D.E. filter creates a layer of filter media around the filtering elements inside. The diatom particles are so fine that they create a network of microscopic tunnels, which captures particles as small as 2-5 microns in size.

What are the benefits of a D.E. pool filter?

D.E. pool filters are highly efficient in removing impurities from the water compared to other filter types. As mentioned earlier, D.E. filters can filter particles as small as 2-5 microns in size, which is far more effective than sand filters which can only trap debris as small as 20-40 microns. D.E. filters can also last longer than sand and cartridge filters as they require less maintenance and backwashing.

What are the maintenance requirements for a D.E. pool filter?

While D.E. filters are highly efficient, they do require proper maintenance to function at its best. First and foremost, you must replace the D.E. powder in the filter from time to time to ensure it remains effective. The frequency of replacement depends on factors such as pool usage, the presence of debris, and the filter size. Additionally, you should backwash your D.E. filter at least once a month or when the filter pressure exceeds 8-10 psi above the starting pressure. Finally, you should also visually inspect the filter's grids or fingers for tears, rips, or other damage that may be causing leaks.

How to install a D.E. pool filter?

Installing a D.E. pool filter can be overwhelming, especially if you have never done it before. However, with the right tools and a little guidance, you can install a D.E. filter with ease. Here's a step-by-step guide on how to install a D.E. pool filter-

1. Turn off the pool pump and electrical supply.

2. Drain any water from the filter or the top valve.

3. Remove the top valve, and then unscrew and remove the retainer ring.

4. Remove the filter grids or fingers and lay them out in a safe place to avoid any damage.

5. Rinse off the filter's manifold and other accessible parts.

6. Fill the filter with D.E. powder according to the manufacturer's instructions.

7. Reinstall the filter grids or fingers and reassemble the filter.

8. Add water to the pool and turn the filter system on.

What are the common issues with D.E. pool filters?

Like any pool filter, D.E. filters can experience issues such as pressure buildup, leaks, and clogging. A common issue with D.E. filters is the formation of "mud balls" - clumps of D.E. powder that can clog the filter and reduce its efficiency. To prevent mud balls, you should add the correct amount of D.E. powder and rinse off the filter grids regularly.

In conclusion, D.E. pool filters are a reliable and effective option for pool owners who seek crystal-clear water and efficient filtration. By understanding the working, maintenance, and installation requirements of a D.E. filter, you can easily maintain its efficiency and enjoy a clean pool.
