SmartPure is the name that Blue Haven pools puts on their SWCGs, Ozone units, and Mineral cartridge systems. As to who actually makes them, it's anyone's guess. This way Blue Haven keeps people coming back to them (and keeps their profit margins up). Del Ozone does make a combo ozone/SWCG called the TrioPure and Autopilot makes the CoPilot addon ozone unit for their PoolPilto SWCGs. My monoy is on the unit being a Del Ozone one.
