How Often Should You Change Your Pool Filter Cartridge


If you own a swimming pool, you understand the importance of keeping the pool clean and safe for swimming. A pool filter cartridge is essential in removing debris and contaminants from the water to ensure the pool remains clean and clear. It provides a barrier to stop larger debris from entering the pool and catches smaller particles that might remain suspended in the water.


While pool owners understand the importance of having a pool filter cartridge, many do not know how often they should change it. In this article, we will discuss how often you should change your pool filter cartridge to keep your pool safe and clean for swimming.


What is a Pool Filter Cartridge?


A pool filter cartridge is a device made of pleated polyester or polypropylene that traps debris and contaminants. It provides a level of filtration between a sand filter and a DE filter, which makes it a perfect option for above-ground and in-ground pools.


The cartridge has a large surface area that filters the water as it passes through the pleats, trapping impurities like hair, dirt, and leaves. It filters out particles up to 10 microns in size, making it effective in keeping the pool clean and clear.


Subheading 1: How Do Pool Filter Cartridges Work?


A pool filter cartridge works by passing water through thousands of tiny pores that trap dirt, debris, and other contaminants. When water flows through the cartridge, the pleats start to fill up with debris, which eventually blocks the flow of water. As the filter becomes clogged, the water flow reduces, causing the pump to work harder to maintain the desired flow rate.


As the pool filter cartridge becomes less efficient, you will notice that your pool water starts to look cloudy, and you may also experience reduced water flow. If you don't change your pool filter cartridge on time, you risk having a dirty pool that can lead to infections and other health hazards.


Subheading 2: Signs that Your Pool Filter Cartridge Needs to be Changed


Determining when to change the pool filter cartridge can be challenging, especially for new pool owners. However, there are tell-tale signs that can help you determine when it's time to change the cartridge.


One sign that your pool filter cartridge needs changing is a drop in water pressure. If you notice that the water flow in your pool is slowing down, it could be a sign that the cartridge is clogged and needs to be changed.


Another sign is an increase in the frequency of backwashing. Backwashing is a process where you reverse the direction of water flow to clean out the filter. If you find yourself backwashing more often than usual, it's a sign that the cartridge is not filtering as efficiently as it should.


Subheading 3: How Often Should You Change Your Pool Filter Cartridge?


Now the important question - how often should you change your pool filter cartridge? The answer is that it depends on how often you use your pool and the type of filter cartridge you are using.


Experts recommend changing your filter cartridge every 12-24 months, depending on how often you use your pool. If you use your pool regularly or have a large family, you may need to change the cartridge more frequently.


Subheading 4: What Factors Affect the Life Span of a Pool Filter Cartridge?


Several factors will determine how long your pool filter cartridge lasts, including:


- Frequency of use: If you use your pool regularly, you will need to change the cartridge more frequently.


- Water chemistry: If your pool water is not balanced, the cartridge is likely to clog faster, reducing its lifespan.


- Type of debris: If your pool is surrounded by trees or has a lot of leaves, you may need to change the cartridge more often.


- Size of the cartridge: Some filter cartridges are larger than others, which means they have a larger surface area that can trap more debris. This means they last longer than smaller cartridges.


Subheading 5: Conclusion


A pool filter cartridge plays a vital role in keeping your pool clean and safe for swimming. You should change your cartridge every 12-24 months, depending on how often you use your pool, water chemistry, debris, and cartridge size.


Ignoring a clogged or dirty filter cartridge can lead to problems like algae growth, cloudy water, and infections. It's always wise to keep an eye on the condition of your cartridge and change it when necessary to ensure your pool remains clean and safe for swimming.
