care routine easier, and keeps your spa water cleaner. All Hot Spring® spas are EverFresh system-ready.
When you fill your spa, the FreshStart®10,000 pre-filter helps to ensure the water is as clean as possible. It attaches to your garden hose, and filters out rust, dirt, detergents, algae and chemicals.
The FreshWater III high output ozone system continuously injects millions of tiny, highly 
concentrated ozone bubbles into the water, neutralizing contaminates on contact. The oxidation process occurs in its dedicated 10-foot contact camber for improved mixing of ozone and minimized off-gassing. Unlike ozone systems that use a UV bulb that needs to be replaced on a regular basis, (at considerable expense), our system uses a Corona Discharge cell that requires virtually no maintenance. Unlike ozone systems which turn off when you're using the jets, the FreshWater III system is at work 24 hours a day.
Silver ions are continuously introduced into the spa water. Our chlorine-free oxidizer activates the silver ions to inhibit the growth of bacteria, refreshing and brightening the spa water. Simply replace the cartridge every four months for on-going protection.
