What is the usual lifespan of a pool sand filter?

The usual lifespan of a pool sand filter is around 5 to 7 years, which aligns with the provided answer. This duration can vary based on several factors, including the quality of the filter, the amount of usage, maintenance practices, and the water chemistry in the pool. Regular maintenance, such as backwashing and replacing the sand as needed, can help extend the life of the filter within this range.

Understanding the lifespan is crucial for pool operators as it helps in budgeting for maintenance and replacement, ensuring optimal filtration and water clarity in the pool. Regular checks can indicate whether a filter is still effective or if it is reaching the end of its useful life, allowing for timely replacement before filtration efficiency declines.
