How Long Should Above Ground Pool Filter Run?

When you take a dip in a crystal-clear above ground swimming pool, it’s easy to forget about the essential bits and pieces that keep your pool water sparkling. One of the most important components of above ground pool maintenance is the filter system. Pool filters are essential in keeping your pool water free from debris, bacteria, and other impurities. But how long should your above ground pool filter run each day for optimal performance?

In this article, we will discuss everything you need to know about how long to run your above ground pool filter. We will also talk about some practical tips that will help you maintain your pool filter system and extend its lifespan.

1. Why is Running Your Pool Filter Important?

Running your above ground pool filter is a crucial aspect of pool maintenance. It helps to remove debris, dirt, and other contaminants from your pool water while keeping it free from bacteria and algae. The filter system also helps to circulate the water, which allows for the distribution of cleaning chemicals and balancing agents. When your pool is running efficiently, you can enjoy clean, healthy water and avoid potential problems that arise from poor water quality.

2. How Long Should You Run Your Above Ground Pool Filter?

The amount of time you should run your above ground pool filter varies depending on several factors. There is no one-size-fits-all answer, but generally, you should run your pool filter for at least eight hours a day. However, the pool size, the filter’s speed, and the frequency of pool use will play a role in how long it should run each day.

Pools that are used more frequently will need to run their filter longer than pools that are used less often. If you have many trees in your yard or live in a particularly dusty area, debris, and dirt will accumulate more quickly, which will mean that your filter will have to run longer.

3. What’s the Best Time to Run Your Above Ground Pool Filter?

The best time to run your pool filter is during daylight hours when the sun is shining. This is because sunlight helps to kill bacteria naturally, which means that there will be less of a bacteria load on your filter system. Running your pool filter during daylight hours will also give the filter system a chance to circulate the water and distribute the cleaning agents and balancing agents for optimal pool health.

4. Is It Necessary to Run the Pool Filter 24/7?

Running your above ground pool filter 24/7 is unnecessary and can be expensive. It can also wear out your pool’s filter system faster. So, it’s essential to run your filter for only the necessary limits. The amount of time your filter needs to operate will depend on your pool size, the pool’s use frequency, and the weather conditions in your area.

5. How to Maintain Your Above Ground Pool Filter?

Maintaining your above ground pool filter is essential to keep it running efficiently for a long time. You should backwash and clean your pool filter regularly to remove debris, dirt, and other contaminants. You should also inspect your filter’s components and replace any damaged parts.


In summary, the duration you should run your above ground pool filter each day depends on many factors. Generally, it’s good to run it for eight hours every day. Still, the size of your pool, the frequency of pool use, the pool location, and environmental factors like trees and dust will all play a role in determining how long to run your filter. Remember to maintain your pool filter regularly and replace any damaged components to ensure that your water remains clean, healthy, and sparkling.
