How Often Should I Run My Above Ground Pool Filter?

Maintaining your above ground pool can be a time-consuming task, but it is necessary if you want to enjoy a refreshing swim in clean and clear water. One of the most crucial parts of pool maintenance is running your pool filter. But how often should you run your above ground pool filter? In this article, we will explore the answer to this question and provide you with tips on maintaining your pool filter.

Understanding Your Pool Filter

Before we dive into how often you should run your pool filter, it's essential to understand the purpose of a pool filter. Your pool filter is responsible for removing debris, dirt, and other contaminants from your pool water. This process ensures that the water is clean and free of bacteria and other harmful elements. Without a properly functioning pool filter, your pool water can become cloudy and unsafe to swim in.

Factors to Consider

Now let's discuss the factors that you should consider when deciding how often to run your pool filter. These factors include the size of your pool, the frequency of use, the climate you live in, and the type of pool filter you have.

Pool Size

The size of your above ground pool plays a significant role in determining how often you should run your pool filter. A general rule of thumb is to run your pool filter for one hour for every 10 degrees of water temperature. For example, if the water temperature is 80 degrees, you should run your pool filter for eight hours a day for optimal filtration.

Frequency of Use

Another factor to consider is how often you use your above ground pool. The more frequently you swim in your pool, the more debris and contaminants will enter the water. As a result, you may need to run your pool filter more often to keep the water clean and clear.


The climate you live in can also impact how often you should run your above ground pool filter. In areas with high temperatures and humidity levels, algae growth can be a significant problem. To combat this, you may need to run your pool filter for longer periods to prevent algae from growing.

Type of Pool Filter

Lastly, the type of pool filter you have will also play a role in how often you should run your filter. There are three main types of pool filters: sand, cartridge, and DE (diatomaceous earth) filters. Each type of filter has its own unique maintenance requirements, which can impact how often you need to run your filter.

Tips for Maintaining Your Pool Filter

Now that you understand the factors that can impact how often you should run your above ground pool filter, let's discuss tips for maintaining your filter.

1. Regular Cleaning

One of the most important things you can do to maintain your pool filter is to clean it regularly. Depending on the type of filter you have, you may need to clean it once a month or more frequently. Regular cleaning will remove debris and contaminants from your filter media, ensuring that it functions properly.

2. Monitor Water Quality

Regularly testing your pool water for pH levels, chlorine levels, and other chemical levels can help you determine the state of your pool water. If you notice that your water quality is declining, consider running your pool filter for longer periods or adjusting your chemical levels.

3. Keep Debris Out

To reduce the strain on your pool filter, make an effort to keep debris out of your pool. Using a pool cover when your pool is not in use can help prevent leaves, dirt, and other debris from entering the water.

4. Refrain from Overusing Chemicals

While chemicals are essential for maintaining clean and clear pool water, overusing them can damage your pool filter. It's important to follow the manufacturer's instructions and use the recommended amount of chemicals to minimize the strain on your filter.

5. Handle Repairs Promptly

If you notice that your pool filter is not functioning properly, address the issue promptly. Ignoring problems such as leaks or blockages can lead to more significant issues down the line, and even result in the need for a new pool filter.

Final Thoughts

Running your above ground pool filter is a crucial aspect of keeping your pool clean and safe to swim in. While the exact frequency of filter use will vary based on your pool size, climate, and other factors, the tips provided in this article can help you maintain your pool filter and keep your pool in top shape.
