Brilliant Water Care For Your Hot Tub
Our EverFresh® system is a pure, natural approach to water care that is virtually chlorine-free. The system combines the cleaning power of ozone with several of our optional FreshWater® water care products. The result is brilliant water, naturally!
Ozone System
All Hot Spring Spas come standard with the FreshWater® III high output ozone
system*. This system continuously injects millions of tiny, highly
concentrated ozone bubbles into the water, neutralizing contaminants
on contact.

The oxidation process occurs in a dedicated 10-foot
contact chamber for improved mixing of ozone and minimized off-gassing.
Unlike ozone systems that use a UV bulb that needs to be replaced
on a regular basis (at considerable expense), our system uses a
Corona Discharge cell that requires virtually no maintenance. Unlike
ozone systems which turn off when you're using the jets, the FreshWater
III system is at work 24 hours a day.
FreshWaterAg+® Continuous Silver Ion Purifier
The FreshWater Ag+ continuous silver ion purifier helps to reduce the need for chlorine by introducing silver ions into the spa water that inhibit bacterial growth. Insert the cartridge into the filter of your Hot Spring spa, and the silver ions are released automatically - there's no chance of under- or overdosing. It's virtually maintenance-free - simply replace the cartridge every 3 months.
MPS Chlorine-Free Oxidizer
This fast-acting formula attacks cell walls to refresh and brighten spa water. When used with the FreshWaterAg+ purifier, the MPS chlorine-free oxidizer helps activate the silver ions so they can do their job more quickly. Plus it's pH neutral, so it won't alter water chemistry.
MPS Test Strips
Use these test strips to monitor your spa's MPS, pH and alkalinity levels when using the MPS chlorine-free oxidizer as a part of the EverFresh® water care system.
