How Often to Clean the Pool Filter

Swimming pools are one of the best amenities a house can have, providing fun and relaxation to the whole family during hot summer days. It's also ideal for hosting pool parties and barbecues with friends, but all of these come with a price. You need to maintain your swimming pool, and one of the most critical factors to consider is the cleanliness of your pool filter.

In this article, we'll talk about how often you should clean your pool filter and the different types of pool filters available on the market.

Understanding Different Types of Pool Filters

Before we dive into how often to clean your pool filter, let's discuss the different types of pool filters. There are three main types: diatomaceous earth (DE) filters, cartridge filters, and sand filters. Each type has unique features and requirements for maintenance.

Diatomaceous Earth (DE) Filters

Diatomaceous earth is a porous powder made of crushed diatom skeletons, and it's one of the best pool filter media. DE filters trap and filter pool water particles and debris that barely visible to the naked eye. DE pool filters require the most maintenance, but they keep the pool water the cleanest.

Cartridge Filters

Cartridge pool filters use an easily removable cartridge consisting of a paper-like material folded into pleats. The number of pleats and material quality varies. Replacement cartridges are readily available, and you can replace them annually or every two years, depending on usage.

Sand Filters

Sand filters are the most common type of pool filter on the market. They use fine sand to filter dirt and debris from the pool water. Sand filters are affordable and easy to maintain. They require the least amount of maintenance among the three types of filters.

Now that we have a better understanding of the types of pool filters let's dive into how often to clean your pool filter.

How Often to Clean Your Pool Filter

We recommend cleaning your pool filter several times a year, depending on your pool usage, water chemistry, and type of filter.

1. DE Filters

Diatomaceous earth filters are the most high-maintenance pool filters, requiring frequent backwashing and cleaning to ensure proper filtration. You should backwash and recharge the DE filter every few weeks, after heavy rains or storms, and a complete cleaning of the filter system at least once a year.

2. Cartridge Filters

Cartridge filters are less demanding than DE filters. However, they still require maintenance to keep them clean and functioning at their best. You should clean your cartridge filter every four to six months or as needed. You'll know it's time to clean your cartridge filter when the water pressure gauge reads a pressure of between 8 and 10 psi higher than the initial pressure level.

3. Sand Filters

Sand filters have the least maintenance of the three main pool filter types. However, they still require maintenance to keep them effective. You should backwash your sand filter every four to six weeks, depending on usage.

Conclusion

Cleaning your pool filter is crucial to keeping your swimming pool clean and safe for your family. We recommend cleaning your pool filter at least several times a year. The frequency of cleaning depends on the type of filter, the size of your pool, and the water chemistry. Don't forget to also maintain your pool's chemical balance and equipment to ensure a happy and healthy swimming experience for everyone.
