We have had the same aero-spa unit for our hot tub since 2014. It is completely worth the investment. It works beautifully, and the water is clear and clean. It is by far the best ozone system we have found with no maintennance. We have ours connected to a timer that runs it when the spa is not in use.

Incredible customer service too as I today I just ordered a sintered diffuser (on the end of the tube) replacment b/c our hard water after many years has turned it dark brown. The person I talked with suggested soaking it overnight in Hydrogen Peroxide first, though I just wanted a clean look. I am so thankful to use a chemical free solution to help keep our hot tub sanitized.

Thank you for creating this product!
