How frequently should a pool filter be replaced?

The correct choice indicates that a pool filter should be replaced every 1-3 years. This time frame allows for proper operation and maintenance of the filter system, as filters are designed to last several years under normal usage conditions. Regular monitoring of the filter’s effectiveness and any changes in water quality can help determine when a filter may need to be replaced.

Factors such as the type of filter, pool usage, and environmental conditions can affect its lifespan. For instance, cartridge filters may require more frequent cleaning, but typically still have a lifespan of several years before needing replacement. This approach ensures that the pool maintains optimal water clarity and sanitation while preventing any major system malfunctions. Keeping the filter in good condition and replacing it at appropriate intervals can lead to better water quality and a healthier swimming environment.
