On average, you replace a spa filter every 2 to 3 months for optimal water quality and proper functioning of your spa. Even with regular cleaning, a filter eventually becomes saturated with dirt, oils, and lime.

How do you know it's time to replace your filter?

Watch for the following signs:
• The filter remains dirty despite thorough cleaning
• The material is damaged (cracks, frays, or deformation)
• The water remains cloudy or smells unpleasant
• The water flow decreases
• Your pump makes more noise or works harder than usual

If you use your spa frequently or with multiple people, it may be necessary to replace the filter more often than every 3 months. For those who want certainty, it is wise to keep a spare filter in stock and regularly alternate.
