How Often to Change Pool Filter: An Essential Guide to Maintaining Your Above Ground Pool

Maintaining your above ground pool can be a daunting task, and oftentimes, it’s easy to ignore the importance of changing your pool filter regularly. However, it is essential to keep your pool filter in proper working condition to ensure that your pool stays clean and safe for swimming. In this article, we will discuss the importance of changing your pool filter, the signs that indicate that it needs to be replaced, and how frequently you should change it.

Why Do You Need to Change Your Pool Filter

A pool filter is an important component of your swimming pool, and it is responsible for filtering out debris, dirt, and other particles from the water. Without a working pool filter, your pool water can become dirty, murky, and unhygienic. When your pool filter is not functioning correctly, it cannot properly remove contaminants from the water, which can lead to a buildup of bacteria, algae, and other microorganisms. This can cause skin irritation, eye irritation, and even ailments such as ear infections.

The Signs That Your Pool Filter Needs to Be Changed

Over time, your pool filter will lose efficiency and will need to be replaced. However, it can be challenging to know when it’s the right time to change it. Here are some signs to look out for that indicate that your pool filter needs to be replaced:

1. Dirty water - If you notice that your pool water is unusually dirty, it may be a sign that your pool filter needs to be replaced. A functioning pool filter should remove most of the visible debris and particles from the water.

2. Decreased water flow - If you notice that your water flow is weaker than usual or if your filter pressure gauge is showing a lower PSI (pounds per square inch) reading, it may be time to replace or clean your pool filter.

3. Strange sounds - If you hear unusual sounds coming from your pool filter, such as grinding, screeching, or rattling, it may be a sign that the filter is clogged or damaged.

4. Frequent cleaning - If you find yourself cleaning your pool filter more often than usual, it may be time to replace the filter entirely.

5. Age - If your filter is older than five years, it may be time to replace it with a new one. Filters tend to lose efficiency as they age, and they will eventually need to be replaced.

How Often Should You Change Your Pool Filter?

The frequency with which you change your pool filter depends on several factors, including the size of your pool, the type of filter you use, the frequency of pool use, and the amount of debris in the pool. In general, it is recommended that you change your pool filter every 2-3 years, but this can vary.

If you have a smaller pool or a low flow rate filter, you may need to change your filter more frequently. A larger pool or a higher flow rate filter may be able to go longer between filter changes. If you live in a particularly dusty or windy area or if you have a lot of trees and plants around your pool, you may also need to change your pool filter more frequently.

However, it is important to remember that regular maintenance and cleaning of your pool filter can extend its lifespan and reduce the frequency with which it needs to be replaced. Be sure to follow the manufacturer’s guidelines for cleaning and maintaining your pool filter, and consider investing in a high-quality filter to ensure that it stays in optimal condition for as long as possible.


In conclusion, a clean and functional pool filter is essential for maintaining a clean and safe swimming environment. By replacing your pool filter on a regular basis and performing regular maintenance, you can ensure that your pool remains crystal clear and that it provides a fun and safe experience for all. Be sure to look out for the signs that indicate that your pool filter needs to be replaced, and change it promptly to keep your pool sparkling clean.
