How and When to Clean Cartridge Filters

If you have a pool with a cartridge filter, it's important to keep it clean to ensure that your pool is running efficiently and keeping your swimmers safe. The frequency with which you need to clean your pool filter depends on several factors, including the size of your pool, how often it's used, and how much debris runs through your filtration system annually.

Pool filter cartridges should be cleaned at least twice a year.

In general, pool owners should aim to clean their cartridge pool filter at least twice a year. If you use your pool frequently, have high bather loads, or if you have a lot of trees in close proximity to your pool, you may need to clean the filter more often. Additionally, whenever your filter pressure rises by 8-10 psi, or if you have an algae outbreak, it’s time to perform a filter clean.

Cleaning your pool filter is essential because it removes debris and contaminants from the water, ensuring that it stays clear and healthy for swimming. Over time, dirt and other debris accumulate in the filter, reducing its effectiveness and making it more difficult for water to pass through. This can cause your pool's circulation system to work harder, leading to increased energy costs and potentially damaging your pool equipment.

To clean your pool filter, start by turning off the pool pump, releasing the pressure from the system, and draining the filter tank. Remove the filter cartridges (usually 4) from the housing and lightly pressure wash them to remove any large debris. Then, place the cartridges back inside the tank and soak the cartridges in a filter degreaser solution, following the instructions on the product label. Once the cartridges have soaked for the recommended amount of time, put the filter tank back together. Turn the pump back on, and your pool will be ready for use.

In addition to regular cleaning, it's also important to replace your pool filter cartridges periodically. Over time, the filter cartridges will become clogged with debris, reducing their effectiveness and making it more difficult for water to pass through. The lifespan of your filter cartridges depends on several factors, including the size of your pool and how often it's used. However, in general, you should aim to replace your filter cartridges every two to three years.

Cleaning your cartridge pool filter is an essential part of pool maintenance that should not be overlooked. By cleaning your filter semiannually, or whenever the pressure is high, you can ensure that your pool stays clean, clear, and healthy for swimming.
