Welcome to our forum.
The Ozone ... Both have it included.Thanks for the thoughts. One thing the HS folks tout is that their filtration system is 100%, i.e., "no-bypass". So that all of the water being pumped goes through the filter. The SD folks indicate about 70% goes through the filtration and the other 30% bypass it and go straight to the pump.Is there any real significance in the difference?
I would test soak to make the final decision. Frankly, anyone on this board can tear apart Sundance and Hot Springs for weaknesses in filtration. They both clean the water great. Just remember to test soak in each seat for a good period of time. Make sure they set the temp to around 100 so you can still think clearly and enjoy soaking for 10 - 30 minutes without getting too tired.
one filter as opposed to multiple filters, filters down to 5 micron with disposable filter (less maintenence)
