Filter cartridge collapses, deforms, or clogs very quickly

Safety first: Unplug the spa before handling the filter.

• Use correct filter: Install the Bestway-specified filter cartridge model for your spa.
• Pre-clean water: Skim large debris before running the pump after filling.
• Rinse frequently: Clean the filter more often if the spa is used heavily or outdoors near trees.
• Replace damaged filters: Discard any collapsed or torn cartridges; do not reuse.

Persistent filter collapse may indicate abnormal suction or blockage in the circulation system, which should be checked by a technician.
