Operation and Filtration Technology
The POOLPURE PDM30 filter utilizes advanced filtration technology to maintain clear and clean spa water.
Trilobal Filtration Fabric
The innovative trilobal fiber structure provides an increased adsorption surface area compared to conventional filter fabrics. This design allows for more efficient capture of dirt and sediment while maintaining consistent water flow and clarity.

Dirt-Lock™ Precision Filtration
Equipped with patented Dirt-Locking Technology and a 50-micron high-efficiency filtration layer, this filter effectively removes up to 99% of fine particles such as hair, leaves, dust, and sand. This results in sparkling clear water and reduces the need for frequent water changes and chemical use.

Troubleshooting

- Reduced Water Flow: This often indicates a clogged filter. Remove and thoroughly clean the cartridge. If flow does not improve, the filter may need replacement.
- Cloudy Water: Ensure the filter is clean and properly installed. Check spa chemical levels and adjust as necessary. If the water remains cloudy, the filter media may be exhausted and require replacement.
- Filter Damage: Inspect the filter for tears, cracks, or excessive wear. Damaged filters should be replaced immediately to prevent debris from bypassing the filtration system.
