You want your ozone in the spa water, not gassing off which can damage covers, pillows, and fittings. The most effective way to get ozone into pool or spa water is to inject it.  

NSF, lab, and field testing proves that Mazzei® Injectors are the best ozone injectors, getting more ozone dissolved in the water where it can quickly kill microorganisms and clean the pool and spa water with no harmful byproducts (just life-giving oxygen).

Our philosophy is to carry the best. For that reason, you will only find Mazzei® Injectors here.
