Filter cartridge collapses or deforms frequently; flow is reduced soon after replacement.

Safety first: Unplug the spa before removing the filter housing.

• Use correct filter: Confirm you are using the correct SaluSpa filter cartridge model recommended for your spa.
• Pre-rinse water: If filling from a well or dirty source, use a pre-filter on the hose to reduce debris.
• Clean more often: Rinse filters more frequently, especially after heavy use or storms.
• Check for downstream blockage: Inspect return ports and internal plumbing for obstructions that could increase suction across the filter.

Warning: Do not operate the spa without a filter; debris can damage the pump and heater.
