If you’re a pool owner, you know how important it is to keep your pool clean and well-maintained. One essential component of pool maintenance is properly caring for your pool filter. The filter plays a crucial role in keeping your pool water clear and free of debris, so it’s essential to make sure it’s functioning properly at all times. We’ll cover the different types of pool filters, how to clean them, and how to tell when it’s time to replace them.
Types of Pool Filters:
Before we dive into the maintenance and cleaning of pool filters, let’s first discuss the different types that are available. There are three main types: sand, cartridge, and diatomaceous earth (D.E.) filters.
Sand filters are the most common type of pool filter. They use sand as the filtration media, which traps dirt and debris as the water flows through it. Sand filters are relatively low maintenance and easy to clean, but they do need to be backwashed periodically to remove the dirt and debris that has accumulated in the sand.
Cartridge filters are another type of pool filter that uses a pleated, paper-like cartridge as the filtration media. These filters are more efficient than sand filters at trapping small particles and are relatively easy to clean. However, they do need to be replaced more frequently than sand filters, as the cartridge will eventually become clogged with dirt and debris.
Diatomaceous earth (D.E.) filters are the most efficient type of pool filter, as they are able to trap even the smallest particles. They use a fine, powdery substance made from the fossilized remains of diatoms (microscopic algae) as the filtration media.
Maintaining Your Pool Filter:
Now that we’ve covered the different types, let’s discuss some general maintenance tips to keep your filter running smoothly.
- Check the filter pressure regularly. Most pool filters have a pressure gauge that tells you the pressure inside the filter. If the pressure is too high, it could be a sign that the filter is clogged and needs to be cleaned.
- Backwash or clean the filter as needed. How often you need to backwash or clean your pool filter will depend on the type of filter you have and the amount of use your pool gets. As a general rule, sand filters should be backwashed every three to four weeks, while cartridge filters should be cleaned every two to four weeks.
- Replace the filtration media as needed. If you have a sand or D.E. filter, you may need to replace the filtration media (sand or D.E. powder) every three to five years, depending on the quality of the media and the amount of use your pool gets.
