About Wind River Spa's (a Denver based company) http://www.windriverspas.com/

Wind River Spa's prides itself on having the closest possible system to Chemically free. This is not to say that you will not have to add chemicals to the water, however; if maintained properly you can get into chemical free water every time you use it. This is only possible because of our continuous clean filtration system. Your spa is designed to filter up to fifty five gallons per minute all day and filters the entire body of water in your spa every 8-10 minutes. It is a combination of this filtration and the latest in ozone technology that enables you to enjoy chlorine, bromine, and peroxide free water every time you soak in your new spa. The reason this is possible is because of the corona discharge ozone that comes standard with every Wind River Spa. This new design of ozone is capable of holding the light frequency needed to create ozone gas almost twenty-four hours a day, everyday for up to five years. The only part of any day that the ozone doesn’t run is the twenty minutes after the spas jet pumps are engaged, (see Ozone in the Safety Features part of the Health and Safety section of the on-line version of this manual).
The ozone gas will eliminate most algae, fungus, or bacteria that could build up in the water when not being used. Regardless of how clean a person is when getting in the spa, the ozone’s sanitizing power is not enough to clean the amount of contaminants a person’s body adds. To ensure the water is clean again for the next use you must add at least half of a teaspoon of chlorinating granules per person each time you get out of the spa. The less often you use the spa the more chlorine you must add after each use, (check the chlorine to usage chart in this section of the manual). By doing this you will sanitize the water as needed based on your usage. Unlike bromine or peroxide a small dosage of chlorine will dissipate in the water after a few hours leaving only Cyanuric acid as a residual. Since Cyanuric acid is harmless and only builds up in extremely small doses, (much of which is burned off by UV from the sun), the water is clean and chemical free the next day when your ready to use it again. To ensure this try to leave 4-5 hours between uses so as to allow the chlorine to dissipate. If more than two people use the spa the dosage of chlorine you add increases so allow more time for the chlorine to dissipate. If anyone chooses to use the spa shortly after chlorine has been added it will still be perfectly safe but the water may smell of the chemical a little bit. Fortunately the amount you add per person is small enough that it shouldn’t be harsh on your skin even if used again directly after being treated.
