What does an ozone generator do in a hot tub?

An ozone generator uses electricity to turn oxygen (O2) into ozone (O3), which is a highly reactive form of oxygen. In hot tubs, ozone generators are used to disinfect the water and oxidize contaminants.

Ozone vs. Chlorine

Ozone is a more powerful oxidizing agent than chlorine, so it can more effectively remove dirt and bacteria from hot tub water. It is also less irritating to skin and eyes than chlorine, which can be beneficial for people with sensitive skin. However, ozone is less stable than chlorine, so it dissipates more quickly from hot tub water. As a result, ozone generators must be run continuously in order to maintain a constant level of disinfection.

Pros of Ozone Generators

* Ozone is more effective at disinfecting than chlorine

*Ozone produces fewer harmful disinfection byproducts than chlorine

* Ozone can help to remove metals, minerals, and organic matter from the water

*Ozone leaves behind no residual chemicals in water

Cons of Ozone Generators

* Ozone can irritate the skin and eyes if not properly managed

* Ozone generators can be relatively expensive to purchase and maintain

*Ozone generators produce a strong smell that some people find unpleasant

* Ozone generators must be vented outdoors to avoid exposing pool swimmers and spa bathers to ozone gas.

Overall, ozone generators can be a valuable addition to hot tubs, but it's important to consider the pros and cons and weigh them against your individual needs and budget.
