A hot tub is actually more sanitary than a pool, because the filtration system is not much smaller than a pool, yet it’s handling much less water…400 gallons versus tens of thousands. There are many different methods for keeping the water sanitized. The most common is chlorine or bromine.
Some of our tubs use a combination of silver ion cartridges and a patented purification system (NOT an “ozonator”). This system is not only patented, but approved by the FDA and UL listed for safety! It makes the tub 90% chemical free.
We also have hot tubs with salt sanitation systems. Salt systems have become very popular in pools over the past few years, and we are the only ones on Long Island that have a salt system for hot tubs.
