How Often Should You Replace Your Cartridge Pool Filter?


Swimming pools are the perfect escape from the summer heat. They can be a source of fun and relaxation, but they also require regular maintenance to keep them in good condition. One of the essential components of pool maintenance is the filter. The pool filter is responsible for removing debris, particles and contaminants from the water, ensuring that the pool remains clean and safe for use. There are different types of filters, but cartridge filters are one of the most popular for residential pools. However, one important question pool owners ask is how often they should replace them. In this article, we will address this concern and provide some helpful tips on maintaining your cartridge pool filter.


What Is a Cartridge Pool Filter?


A cartridge pool filter consists of a cylindrical cartridge that is made of pleated polyester material. The pleats trap debris and contaminants as water passes through the filter, leaving clean water to return to the pool. Cartridge filters have a larger surface area than sand filters, allowing them to filter finer particles while also requiring less backwashing. They are also eco-friendly as they don't require backwashing, reducing water waste.


Factors to Consider When Replacing Your Cartridge Pool Filter


1. Frequency of Use


The frequency of use is a crucial factor to consider when replacing a cartridge pool filter. If you use your pool often, you may need to replace the cartridge more frequently. The amount and type of debris entering the pool also affect how often you'll need to replace it.


2. Type of Pool


Whether it is an outdoor or indoor pool can also influence the frequency of replacement of pool filters. Outdoor pools are exposed to various weather conditions, having an impact on filters' lives. Indoor pools have less exposure to the elements, making them easier to maintain hence cartridges can last longer.


3. Pool Water Treatment


The use of chemicals and treatments such as chlorination can also reduce the life of the cartridge. The chemicals and maintenance practices should be moderate. Avoid excessive backwashing and rinsing, as this can damage the pleats, decreasing the filter's effectiveness.


4. Filter Size


The filter size will also dictate the frequency of cartridge replacement. Pools with larger filters can go longer without needing a replacement. Smaller filters have to work harder to maintain cleanliness and will require more frequent changes.


5. Water Source


The water source also influences how often you'll need to replace your pool filter. Hard water sources have minerals and dissolved solids that can clog the filter quickly. Soft water sources have fewer minerals and particulates, allowing filters to last longer.


When to Replace Your Cartridge Pool Filter


On average, a cartridge pool filter can last between two and five years. However, different factors can influence how often you should replace it. You can inspect the cartridge to see if it requires a replacement. If the cartridge is discolored, clogged, or torn, it may be time to replace it. Another sign is a decrease in water flow rate through the pool's return. Decreased flow rate indicates a clogged filter.


It's important to note that replacing your cartridge pool filter is necessary for your pool's optimum performance. Dirty pool water is the result of a poorly maintained filter, making the water unsuitable for swimming.


Conclusion


Maintaining your pool is essential to keep it in good condition and maximize its use. Replacing your cartridge pool filter is an important aspect of pool maintenance. Filter life can vary depending on usage, pool size, water source, and other factors. You can inspect the cartridge to determine if it requires replacement. Don't overlook pool maintenance, as neglect can lead to a filthy pool and higher costs in the long run. By following the tips outlined in this article, you can replace the cartridge on time and avoid costly damages.
