Master Clear Salt System
We Didn't Want a Salt System. We Wanted a Better One.
Saltwater technology isn't new to hot tubs. Master Clear is Master Spas' answer for why so much of it wasn't worth recommending.
Saltwater, Reengineered
An accessory we're actually excited to recommend
For years, saltwater systems have shown up on spa order forms because customers asked for them, not because dealers were excited about what they did. Softer water and less manual chlorine were real advantages, but they came with real compromises — too much salt accelerates corrosion, and a system that generates chlorine on a fixed schedule doesn't know or care how much your spa got used that week.
Master Clear was engineered around those specific problems. Instead of adding a generic salt generator and calling it a feature, Master Spas built a system around the ownership experience. It watches the water instead of running on a timer.
It's the first saltwater system we've felt good about putting in front of you.
Less Salt, Less Guesswork
Engineered to run at a lower salinity
Higher salinity can mean faster corrosion around heaters and other components. Master Clear was built to deliver the feel of saltwater at a meaningfully lower concentration.

How It Works
Engineering you don't have to think about
The Smart Cell
Living in the filter well, the Smart Cell tests the water and generates sanitizer on its own. It runs more when the spa sees more use, and backs off when it doesn't. Replace it once a year and you're done; there are no separate cartridges or generators to manage.
Your Water, On Your Phone
The Master Clear app connects to your spa so you can check salt and sanitizer levels and make adjustments from your phone, instead of guessing or reaching for a test strip every time.
Water That Feels Like Water
Softer on skin and eyes, with less of the chemical smell people associate with a traditionally maintained hot tub. You'll still need to keep an eye on basics like pH (no system removes that), but Master Clear handles the sanitizer side of it automatically.
Why We Showcase Master Clear
There are plenty of accessories we can sell. Master Clear is one we want to demonstrate. It was built around the specific reasons saltwater systems earned a mixed reputation in the first place, not as a box to check. Master Spas waited until it had a system worth putting its name on.
We put it front and center, not on the back shelf.
Master Clear is available on Legend Series, Twilight (excluding TS 240X), Clarity, and LH Spas. Ask us whether it's a fit for the model you're considering.
