Meet Charles Mitsis.
As owner and president of SpectraPure®, Charles brought the company to life from a 13-year background as an inventor, chemist, engineer, and scientist in the aerospace industry — working in the R&D lab at Litton Electron Devices on advanced night-vision technology.
With over 38 years of water chemistry and engineering experience, he's still the driving force behind every product and solution we ship.
Engineered, not assembled.
Every system we sell is built by hand in Tempe, Arizona — and every membrane is processed and tested in our own facility before it reaches a customer. That commitment to in-house manufacturing means we know the rejection curve, flow rate, and pressure drop of every component we sell. When you call for technical support, you talk to one of our engineers — the same people who built your system.
Industry-leading design and quality.
Custom blended resins. All of our resin is rinsed and mixed in house to ensure the highest quality DI on the market.
Built from the fittings up. We hand-build and test all of our systems using only the best components — so you're getting a quality system every time.
Designed with precision. All of our pumps and electronic components are constructed and tested in-house to ensure accuracy and longevity for years to come.
What we make.
Reverse osmosis and RODI systems for drinking water, reef-keeping, hydroponics, coffee, and laboratory applications. Replacement membranes, filters, and resin. Type II / III lab water systems and high-volume commercial RO. Test gear and water quality instruments.
Where we are.
SpectraPure is based in Tempe, Arizona. Our facility houses membrane processing, system assembly, water testing, and our customer service and engineering teams.
