How Long to Run Your Pool Filter in Summer

If you have a pool, you know the importance of keeping it clean and clear. A crucial component of pool maintenance is your pool filter. But with so many different factors to consider, you may be left wondering how long should you be running your pool filter in the summer. In this article, we'll explore everything you need to know to maintain your pool properly.

Why is Pool Filtration Important?

Before we dive into the specifics of running your pool filter, let's quickly review why it's such an important part of sustaining a healthy pool. A pool filter removes dirt, debris, and other contaminants from your pool water, helping to keep it clear and safe. Without proper filtration, particles can accumulate in the water, leading to buildup on the surface, making the pool more difficult to clean and maintain. Additionally, if the water becomes too dirty, it can harbor bacteria and other microorganisms that can be harmful to swimmers.

How to Determine Your Pool Filter Run Time

The length of time you need to run your pool filter depends on several factors:

Pool Size: Larger pools typically require more time to filter the water thoroughly.

Bather Load: The more people using the pool, the more contaminants will be introduced to the water, requiring more frequent filtration.

Temperature: Warmer water can encourage the growth of algae and bacteria, requiring longer filtration times to maintain water clarity and quality.

Wind and Rain: Wind can bring debris and particles into the pool, increasing the amount of dirt and debris to be filtered out. The same applies after heavy rainfall.

Generally, it's recommended to run your pool filter for eight to ten hours a day during the summer. However, it's essential to customize this run time for your specific pool circumstances. You can start by running the filter for eight hours a day, and then adjust it based on the water's condition.

How to Monitor Your Pool Water Quality

Keeping an eye on your pool water's quality is crucial to determine how much time you need to run your pool filter. Make sure you check the pool water at least once a week using water test strips that measure pH, alkalinity, and chlorine levels. If you notice any changes in these levels, it's essential to adjust the chemical balance of the pool water to keep it clean and clear, using the appropriate chemicals such as chlorine, pH increaser or decreaser and alkalinity increaser. If you give your water the appropriate chemicals, then your need to run the filter time will reduce.

How to Increase Your Filter's Efficiency

Running your pool filter for long hours can lead to higher energy bills, but there are ways to improve its efficiency, such as:

Using a variable speed pool pump which can significantly reduce energy consumption while still maintaining performance.

Regularly clean or backwash the pool filter to increase its efficiency.

Reduce your pool pump's run time during cooler temperatures, such as late fall and winter.

Use a pool cover to prevent dirt and debris from entering the water and reducing evaporation.


Running your pool filter for the right amount of time is critical to ensure your pool's water is clear and safe. Spending a few minutes monitoring the pool water's chemical levels and following a routine cleaning and maintenance schedule can help you maintain your pool's clarity while conserving energy. Always refer to the manufacturer’s manual guide for specific advice as the pool filter needs may vary.
