Summer is finally here and you've likely uncovered your pool and are ready to jump in for some refreshing fun in the sun. But before you can do that, you need to make sure your pool is clean and healthy. One essential part of pool maintenance is ensuring that the pool filter runs for the correct number of hours each day. In this article, we will discuss how many hours to run a pool filter in summer, and why it is important.

Why is Running Your Pool Filter Necessary?

Before we dive into the specifics of how long a pool filter should run, it's important to understand why your pool filter needs to be running in the first place.

A pool filter's main function is to remove unwanted debris and contaminants from the pool water. Without a pool filter, debris such as dirt, leaves, and other organic matter would build up in the pool and create an unclean, unsanitary swimming environment.

In addition to removing physical debris, pool filters also help remove algae, bacteria, and other microorganisms that can cause illness or skin irritations.

How Long Should You Run Your Pool Filter?

There is no one-size-fits-all answer to this question, as it depends largely on the size of your pool, the type of filter you have, and the climate of your location.

However, a general guideline is to run your pool filter for 8-12 hours per day during the summer months. During the winter months, you can reduce this time to 6-8 hours per day.

It's important to note that if your pool is heavily used (e.g., if you host regular pool parties), you may need to run your filter for longer to ensure the water remains clean and clear.

Five Factors That Affect How Long You Should Run Your Pool Filter

As mentioned, there are several factors that can affect how long you should run your pool filter. Here are five key factors to consider:

1. Pool Size: The larger your pool, the longer you will need to run your filter. This is because a larger pool requires more filtration to keep the water clean.

2. Type of Filter: There are three main types of pool filters: sand, cartridge, and DE (diatomaceous earth). Each type has different flow rates and filtration abilities, which can affect how long you will need to run your filter.

3. Climate and Temperature: The climate in your location can also affect how long you need to run your filter. In hotter, sunnier climates, you may need to run your filter for longer to prevent algae growth.

4. Usage: If you use your pool frequently, you may need to run your filter for longer to keep up with the increased demand on the filtration system.

5. Chemical Levels: Finally, the chemistry of your pool water can also affect how long you need to run your filter. For example, if your pool has high levels of phosphates, you may need to run your filter for longer to prevent algae growth.

Tips for Saving Energy While Running Your Pool Filter

While it's important to run your pool filter for the appropriate amount of time, it's also important to consider ways to save energy and reduce your pool maintenance costs. Here are a few tips:

1. Use a Timer: Use a timer to automatically turn your pool filter on and off at specific times. This ensures that you don't forget to turn it off and waste energy.

2. Use a Variable-Speed Pump: A variable-speed pump can help save energy by allowing you to adjust the speed of the pump based on how much filtration your pool needs.

3. Clean Your Filter: Regularly cleaning your filter can help ensure that it runs efficiently and doesn't require more energy than necessary.

4. Cover Your Pool: Finally, covering your pool when it's not in use can help reduce the amount of debris that enters the water, which means you may be able to run your filter for shorter periods of time.


Running your pool filter for the appropriate amount of time is essential for maintaining a clean, healthy swimming environment. By considering the factors discussed above and following our tips for saving energy, you can ensure that your pool is always ready for a refreshing dip.
