Amazingly clear water due to our synergy water purification system. Passion Spas are equipped with a multi-faceted water purification system that helps keep your water crystal clear and reduces the need for additional water sanitation and maintenance. The sole purpose of our dedicated filtration pump is to draw water through the spa filter, insuring that your spa water is constantly being filtered regardless of whether the massage pumps are operating. The water is sanitised by means of our highly effective Ozone System and, in our Signature and Exclusive Collections, further purifi ed with our UV sanitation system. The combination of 100% filtration, ozone sanitation and UV purifi cation creates our Synergy Water Maintenance System that creates the ultimate in clear water.
