What is an Earth Pool Filter

Swimming pools require proper filtration to maintain clean and clear water. One of the most common types of pool filters is the earth pool filter. In this article, we will explore what an earth pool filter is, how it works, why it's beneficial, and how to maintain it.

What is an Earth Pool Filter?

An earth pool filter, also known as a diatomaceous earth (DE) filter, is a type of pool filter that uses a fine powder made from the fossilized remains of diatoms, a type of hard-shelled algae. The powder is coated on a grid of plastic or metal inside the filter tank, forming a layer of tiny pores that trap dirt and debris as water flows through.

How Does an Earth Pool Filter Work?

The earth pool filter works by forcing the pool water through a series of grids coated with diatomaceous earth, which traps debris and particles as small as 5 microns. As the earth pool filter captures dirt and debris, the filter pressure increases, indicating it's time to backwash the filter, or remove the accumulated debris caught in the filter.

Why is an Earth Pool Filter Beneficial?

Earth pool filters are effective and efficient when it comes to filtering out dirt and debris from pool water. Unlike other pool filters, such as sand or cartridge filters, earth pool filters can remove particles as small as 5 microns. This filtration process results in clean and clear pool water, which reduces the need for chemicals, and lower maintenance costs.

How to Maintain an Earth Pool Filter

Maintaining an earth pool filter requires regular cleaning and inspection. The following are steps to help maintain an earth pool filter:

1. Backwash: Backwashing should be done when the filter pressure gauge indicates that the pressure has increased by 8-10 pounds per square inch (psi) above the starting pressure.

2. Clean Filter Grids: The filter grid should be removed and cleaned periodically, typically once or twice a year, using a hose or a pressure washer.

3. Replace DE Powder: Add the correct amount of diatomaceous earth powder to the filter after cleaning or backwashing.

4. Inspect Gaskets and O-rings: Inspect all gaskets and o-rings for cracks or damage. Replace if necessary.

5. Check Water Balance: Unbalanced water chemistry can affect the efficiency of the filter. Test the water regularly, and make necessary adjustments as needed.

In Conclusion

An earth pool filter is an excellent option for pool filtration. It effectively removes dirt and debris from pool water, resulting in clean and clear water. Maintaining an earth pool filter requires regular cleaning and inspection to ensure its proper operations. By following the tips above, you can ensure that your earth pool filter is working efficiently, which will result in a longer-lasting pool filter and reduced maintenance costs.
