I respectfully disagree. To me, there seems to be much more research suggesting Microban is effective than not. We are getting off topic though...The question at hand is, do Master Spas no longer have Microban available in most of their shells? Yes or No? It would be could to hear from the factory themselves on this.
I have not heard a thing, maybe it was a cost cutting decision.
Kind of weird, it had a strong presence on their website and suddenly disappeared...
