Customers often ask us if it is recommended or necessary to change their pool filter sand. The answer isn’t quite as simple as a yes or no. Even pool industry professionals are on the fence on the topic.
Let’s explore both sides of the debate.
Why Some Say NO to Changing Your Pool Filter Sand
The most common reason professionals say there is no need to change your filter sand is because sand lasts forever and need not be replaced. For maintenance, they suggest cleaning it about once a year with a professional sand cleaner.
Why Others Say YES to Changing Your Pool Filter Sand
The professionals that recommend changing your pool filter sand argue that not only should you replace your sand every 3-5 years, but you should also clean it in the interim. The argument for changing the sand is based on the belief that sand does eventually wear down and become smooth. When this happens, the sand cannot trap debris as well and it is time to replace it.
To Change or Not to Change
Filter manufacturers generally recommend changing your pool filter sand every few years. Since these companies manufacture the filters, they have nothing to gain from selling you new sand. We would advise following the manufacturer’s recommendations.
While the final decision is yours, we would advocate for changing your pool filter sand every 3-5 years.
