Clear water
"I haven’t owned a spa before this one and one of my deterrents was due to water maintenance. Growing up we had a pool, and the cost and time of maintenance was something I didn’t want to deal with. Then I heard about Jacuzzi® True Water™. It required very little maintenance to have clear water and no chemical odor. Being skeptical, I did some research and saw many companies offering multiple solutions for sanitary spa water. Jacuzzi® True Water™ stood out because it uses a more natural approach to clean water. After first using it, my skepticism still existed, clear water, no chemical smell, not feeling like I need to rinse off after exiting the spa…could this really be sustainable? As time went on, each time I approached the spa I prepared myself that today is the day it will be smelly and be unable to use. It never has. I still exit the clear water not needing to rinse, no chemical residue and with very little maintenance I can do myself."
Effortless
"Finally, I no longer need to think about taking care of my hot tub water, just change my cartridge monthly and water is crystal clear, almost no effort. I spend so much more time taking care of my pool, wish I had True for it. My wife also never used hot tub before the system because she hated the smell and feel of lots of chlorine in the water. Now, she doesn’t even notice any chlorine smell and now she can enjoy some hot tub hydrotherapy.""
GREAT water care system!
"We live in the country on well water. When we filled the tub, we used an inline filter. The water was still very yellow due to iron. My father in law said "wow, I would not get in that!". The next morning, we opened the cover and it was crystal clear water! It has remained so for the past month without the smell of chlorine or the maintenance that we had with our old tub. GREAT water care system!""
Remarkable
"Water quality is perfect, I have owned several hot tubs in my lifetime but this Jacuzzi® True Water™ system is truly remarkable. In less than 8 hours my water was crystal clear and it has stayed that way ever since. The water smells nice and clean, it feels great and it took very little work to get it that way. Easiest setup ever!""
Game changer!
"Game Changer! I have been using the True Water™ technology for nine months. I do not have a lot of time for spa water maintenance, this has been the best solution! Family members have commented they do not have that chlorine smell or do not have itchy skin caused by normal water maintenance. I highly recommend the True Water™ System!""
