Everyone deserves a hot tub from The Hot Tub Store.
Cleaner water with fewer chemicals, around the clock. The FreshWater® Ozone System continuously injects ozone — a powerful natural oxidizer — into your spa water, neutralizing contaminants before they can cloud your water or demand more sanitizer.
Ozone breaks down lotions, oils, and other contaminants on contact — so your sanitizer works less, and your water stays clearer, longer.
By oxidizing contaminants continuously, ozone reduces the sanitizer your water needs — gentler on skin, eyes, and swimsuits.
The system injects ozone whenever your spa circulates — quietly cleaning between soaks, with nothing for you to dose or remember.
Ozone leaves no residue and no odor behind — just noticeably clearer water that's always ready when you are.
Set-and-forget water care that runs with your spa's circulation system.
An ozone generator in the equipment bay produces ozone from the air — no cartridges to fill and nothing to pour.
As water circulates, ozone is injected and dissolved into the stream, reaching every corner of your spa.
Ozone neutralizes oils, lotions, and other contaminants on contact, then reverts to plain oxygen — leaving nothing behind.
Ozone isn't a stand-alone sanitizer — it's the workhorse that lightens your sanitizer's load. Paired with a chlorine routine or the FreshWater® Salt System, it keeps water quality high while keeping chemical use low.
The FreshWater® Ozone System is available for both of our premium spa lines — whichever brand fits your backyard, cleaner water comes with it.
Available across the Hot Spring® lineup — factory-installed on select models and available as an option on others.

Available across the Caldera® lineup as part of a complete water care setup — ask us about the right configuration for your model.
Explore Caldera® SpasNo — ozone is an oxidizer, not a residual sanitizer. It dramatically reduces how hard your sanitizer works, but you'll still maintain a low level of chlorine or use the FreshWater® Salt System alongside it.
Yes — the ozone is injected and dissolved into the circulating water, where it does its work and then reverts to plain oxygen. It leaves no chemical residue in the water.
The FreshWater® Ozone System fits ozone-ready Hot Spring® and Caldera® spas. Tell us your model and year and we'll confirm compatibility and pricing.
Very little. Ozone generators do wear over time, so plan on a periodic replacement — we'll check yours during routine service and let you know when it's due.
FreshWater® IQ monitors your water and tells you (or doses) what it needs; the Ozone System actively cleans the water continuously. They address different parts of water care and work well together.
Stop by a showroom or reach out — we'll help you configure the right water care setup for your spa.
