Keeping your pool water crystal clear and hygienic requires constant maintenance, and filters play a significant role in this process. The filter cartridge, in particular, traps and removes debris, dirt, and other contaminants from the water. If not properly maintained, they can become clogged and strain your equipment, leading to a decrease in water flow, increased pressure on the pump, and even damage to the filter itself.

Replacing your pool filter cartridge is an essential part of maintaining a healthy pool. It can be a daunting task for beginners, but it is important to understand how often you need to replace your cartridge and how to do it. Here is a guide to help you understand when it is time to swap out your filter cartridge.

1. Know The Type Of Pool Filter You Have

If you are not sure about the type of pool filter you have, it is essential to check the manufacturer's documentation or ask a professional to help. All pool filters have different lifespans. For instance, a sand filter can last up to five years, while a cartridge filter may last up to a year.

2. Understand Your Pool's Usage

The frequency of pool usage affects the lifespan of the pool filter. If you have a busy pool with a lot of swimmers, you may need to change your filter more often than someone with a pool that only has a few swimmers. Consider the number of people, the duration of pool use, and the frequency of pool use when determining how often you need to change your filter.

3. Keep An Eye On The Filter's Pressure Gauge

One of the simplest ways to determine if a filter is due for replacement is by checking the pressure gauge. In general, when the pressure gauge reading reaches 8-10 PSI above the starting pressure, it's time to clean or replace the filter cartridge. However, this varies from filter to filter, so please refer to your owner's manual.

4. Observe The Condition Of The Filter

If your filter cartridge's pleats or fins are damaged, frayed, or broken, it is time to replace the cartridge. When these components get damaged, they are no longer effective in trapping debris and dirt, which will lead to dirty pool water.

5. Pay Attention To Water Clarity

If the pool water starts to look cloudy, even though you've balanced the chemicals correctly, then it's time to replace the cartridge. When the filter starts struggling to keep up with the pool's cleanliness, the water will start to get hazy; changing the filter cartridge will help solve this problem.

In conclusion, a clean pool depends on a good pool filter cartridge. Regular inspection of your filter cartridge can help you detect when it's time for replacement, depending on your pool usage and the type of filter you have installed. Remember to follow the owner's manual when replacing the cartridge or ask a professional for assistance. With proper care, you can extend the lifespan of your pool filter cartridge and maintain a crystal clear pool.
