  • <h4 class="dechead">On One Hand: Average sand filters last four to five years

    Most pool specialists will recommend changing the sand in your pool filter every 4 to 5 years if you are using chlorine as a pool sanitizer and you regularly maintain your pool filter by backwashing the filtration system.

    On the Other: Some factors require more frequent care

    If you use a biguanide sanitizer for your pool system, the sand in your pool filter should be changed every 3 to 5 years. Poorly maintained pools or pools with insufficient water chemistry may also require you to change your pool filter sand more frequently as well.

    Bottom Line

    The length of time that your pool filter sand lasts is largely dependent upon how well your swimming pool is maintained. Proper maintenance to ensure your water chemistry remains ideal and routine backflushing of the filtration system will help to eliminate the need for a filtration system overhaul.
