💬 Southern Leisure Says

The Simplicity system makes filter maintenance much easier than traditional cylindrical cartridges. Check the filter monthly and either rinse it thoroughly or replace it, depending on its condition.

A four-pack gives you enough filters to keep replacements on hand instead of waiting until a dirty or restricted filter begins affecting water flow.

🧼 Care & Maintenance

• Inspect the filter every four weeks or sooner during heavy spa use.
• Turn off power to the spa before removing the filter holder.
• Rinse along the pleats from one side to the other using a garden hose and nozzle.
• Rinse thoroughly to remove loosened debris.
• Do not use a pressure washer, stiff brush or sharp cleaning tool.
• Allow a cleaned filter to dry thoroughly when rotating between filters.
• Replace the filter if it becomes torn, misshapen, heavily stained or permanently restricted.
• Replace each filter at least every 12–16 weeks, or sooner when needed.
• Maintain balanced water chemistry to help improve filter performance and service life.
