What is a Cartridge Pool Filter and How Does it Work?

If you are considering installing a pool or need to upgrade your pool filter system, you may have heard of a cartridge pool filter. In this article, we will discuss what a cartridge pool filter is, how it works, and the advantages and disadvantages of using it.

What is a Cartridge Pool Filter?

A cartridge pool filter is a type of pool filter that utilizes a replaceable cartridge to filter out impurities in a swimming pool. The cartridge is made up of pleated fabric, typically polyester, that traps debris as water flows through it. Cartridge pool filters are usually housed in a tank or canister and installed after the pool's pump and before the pool's return jets.

How Does a Cartridge Pool Filter Work?

When the pool pump operates, water is drawn from the pool through the skimmer and main drain and pushed through the cartridge pool filter. As water flows through the pleated fabric cartridge, debris such as dirt, leaves, bugs, and other impurities are trapped in the cartridge. The cleaned water then returns to the pool through the return jets. Cartridge pool filters typically require regular cleaning, and the cartridges need to be replaced periodically depending on how much they are used.

Advantages of Using a Cartridge Pool Filter

1. Easy to Maintain

One of the significant advantages of using a cartridge pool filter is that it is easy to maintain. Unlike sand or diatomaceous earth (DE) pool filters, which require backwashing or flushing, cartridge pool filters need only to be removed, hosed down, and replaced. This process removes debris from the cartridge, which then continues to filter the pool water.

2. Lower Operating Cost

Cartridge pool filters have a lower operating cost than other types of pool filters. They require less water to operate because they do not need backwashing or flushing, and this can save money on water bills. Cartridge pool filters also use less electricity than sand or DE pool filters because they operate at a lower pressure, resulting in lower power consumption.

3. High Filtration Capacity

Cartridge pool filters are known for their excellent filtration capacity. They can remove dirt, debris, and other impurities from the pool water down to a size of 10 microns, which is smaller than the width of a human hair. This means that the water in the pool will be clearer and free from contaminants that can cause health problems.

4. Eco-Friendly

Cartridge pool filters are more eco-friendly than other types of pool filters. They do not require chemicals such as DE powder or pool sand, which can be harmful to the environment. Also, because they require less water and electricity to operate, they have a lower carbon footprint than other types of pool filters.

5. Quiet Operation

Cartridge pool filters operate quietly, which is an advantage for those who live near the pool. Sand and DE pool filters can be noisy, especially when backwashing, whereas cartridge pool filters produce minimal noise.

Disadvantages of Using a Cartridge Pool Filter

1. Potential Clogging

One of the significant disadvantages of using a cartridge pool filter is that the cartridge can become clogged, especially if the pool has high levels of dirt and debris or is located in an area with high pollen or dust levels. When a cartridge becomes clogged, it can reduce the filter's effectiveness, which can lead to cloudy or dirty pool water.

2. Need for Regular Maintenance

Although cartridge pool filters require less maintenance than sand or DE pool filters, they still require regular cleaning. The cartridges need to be removed, hosed down, and replaced periodically to maintain their effectiveness. Failure to do so can lead to clogging and other problems.

3. Initial Cost

Cartridge pool filters have a higher initial cost than sand filters but are less expensive than DE pool filters. However, the cost of the filter often depends on the size of the pool, the filter's efficiency, and the manufacturer.

Conclusion

A cartridge pool filter is an excellent option for those who want a low-maintenance, efficient, and eco-friendly pool filter. Although there are some disadvantages, such as the potential for clogging and the need for regular maintenance, the advantages far outweigh the disadvantages. When choosing a cartridge pool filter, it is essential to consider your pool size, usage, and filtration needs, as well as the manufacturer's reputation and warranty.
