Welcome to our forum.
Since other brands already have their filteration systems and purifacation systems (ozone) approved by N.S.F. What is left for them to approve the whole spa. Since the N.S.F. really only cares about sanitation its not like they are looking at insulation or frames. Sounds to me like the "marketing machine" otherwise known as hotsprings is at it again. I bet h.s. was the first company to ever try to get the entire spa approved. If you want to pump up h.s. do it the real way and talk about some of the truely good features h.s. has. Let lay off the marketing ploys
I changed the address, just forgot to change it here, thanks for the info
Sorry, but this is an exciting new certifiication, and I would suggest not trying to minimize it since the various other brands will most likely be climbing on board asap. Try to downplay it today, end up selling it/buying it next year.
Dd I miss it? What is about HS filtration that makes it safer?
