Ultra Pure Management System

D1 patented water management system uses low power 98 watt circulation pumps to purify your water. In fact, 84% of the power that UltraPure uses is returned to the water as heat warming your hot tub or free.

UltraPure PLUS offers a double-dose of microorganism destruction, once with ozone (a patented D1 process) and once with the new UV light germicidal, a more natural, non-chemical approach to disinfection. Minimize chemical use and cost. Limit the amount of time you spend on water maintenance. Get ultra clean, crystal-clear water and peace of mind. UltraPure PLUS is a new standard feature on hot tubs in the company’s Bay Collection line.
