how often should you clean pool filter


Author: Poolking - Swimming Pool Equipment Manufacturer

One of the most important aspects of keeping your pool sparkling clean is maintaining a well-functioning pool filter. Your pool filter is responsible for removing debris, dirt, and other contaminants from your pool water, keeping it safe and healthy to swim in.

However, a common question that many pool owners have is how often they should clean their pool filter. In this article, we will discuss the recommended pool filter cleaning schedule, how to clean different types of pool filters, and the importance of regular pool filter maintenance.

Understanding Your Pool Filter

Before we dive into the cleaning process, it's important to understand the different types of pool filters available:

1. Sand filters: These filters use sand to trap dirt and debris as water flows through them. They are very popular due to their low maintenance requirements and can last for up to five years.

2. Cartridge filters: These filters use a cartridge to catch small dirt and debris particles. They require more frequent cleaning than sand filters, and the cartridge typically needs to be replaced every three to five years.

3. Diatomaceous earth (DE) filters: These filters use a fine powder made from the fossilized remains of diatoms to catch small particles. They are the most effective type of pool filter but require the most maintenance.

Now that you understand the different types of pool filters let's explore how often you should clean them.

How Often Should You Clean Your Pool Filter?

The frequency of pool filter cleaning largely depends on how frequently you use your pool. A general rule of thumb to remember is the more you use your pool, the more frequently you should clean your filter. Here are some general guidelines:

- Sand filters: These filters only require cleaning once or twice a year. However, you should backwash the sand filter every four to six weeks to remove any buildup and keep it functioning correctly.

- Cartridge filters: These filters should be cleaned every two weeks and replaced every three to five years. However, if you use your pool more often or notice that the filter is becoming clogged, then more frequent cleaning is necessary.

- DE filters: These filters require the most maintenance and should be backwashed once a month and disassembled and cleaned at least once a year.

The Importance of Regular Pool Filter Maintenance

Regular pool filter maintenance is essential for keeping your pool water clean, clear, and healthy. A dirty or clogged filter hinders water flow and affects the pool's chemical balance. This can lead to algae growth, cloudy water, and even skin and eye irritations.

Additionally, neglected filters can increase energy usage by up to 20%, which can raise heating costs and put a strain on your pool's electricity consumption.

How to Clean Your Pool Filter

Now that you understand how often to clean your pool filter, let's cover the proper cleaning process for each type of filter:

1. Sand filters:

- Turn off the pool pump and switch the valve to the backwash setting.

- Turn on the pump and let it run until the water coming out is clear.

- Turn off the pump and switch the valve to rinse. Turn the pump back on for 30 seconds.

- Turn off the pump and switch the valve to filter.

- Turn the pump back on, and you're done.

2. Cartridge filters:

- Remove the cartridge from the filter and hose it down with a high-pressure hose.

- Soak the cartridge in a filter cleaning solution for at least 12 hours.

- Rinse the cartridge with a high-pressure hose and let it dry.

- Finally, reassemble the filter and the cartridge, and turn on the pump.

3. DE filters:

- Turn off the pump and close the main drain.

- Remove the clamp or band holding the filter top in place.

- Remove the filter top and disassemble the filter.

- Hose down the grids or fingers using a high-pressure hose.

- Soak them in a filter cleaning solution for at least 12 hours.

- Rinse the parts with a high-pressure hose and let them dry.

- Reassemble the filter and turn on the pump.

In conclusion, keeping your pool filter clean is essential for maintaining a well-functioning pool that is healthy to swim in. By following the recommended cleaning schedule, you can ensure that your pool filter remains in top working condition, your pool water stays clean, and your energy costs are kept to a minimum.
