Innovators In Water Technology

Being the first company to introduce the combination of Reverse Osmosis and Deionizing filtration to the aquarium industry, SpectraPure is driven by the scientific approach; research, design, test, manufacture and market.  

SpectraPure excels in the field of innovation, continually pushing the envelope. This approach has brought significant return on investment for SpectraPure, as it continues to develop products of high performance for a growing industry.  

From drawing board to finished product, SpectraPure strives to outperform comparative products within the various industries requiring ultra-pure water. Examples of this are our unique mixes of scientifically designed DI resin compounding and high performance RO membranes, following our proprietary processes for performance improvements. Coupled with these significant improvements to the components making up water purifications systems, are the methods of interconnecting and managing the flow and recirculation of purified water to eliminate contaminates, with the end result of Ultra-Pure water for scientific applications.

At SpectraPure, we have the science to back up our statements of producing Ultra Pure water and that is what makes us different from our competitors!  

As the owner and President of SpectraPure, Charles carries the vision of SpectraPure from a 13 year background as an inventor, chemist, engineer and scientist in the aerospace industry working in the Research & Development lab at Litton Electron Devices, with the development of technologies in the field of advanced night vision.  

Charles has dedicated his life to perfecting Water Purification technology and is a Resin and Membrane Expert. Our systems with our superior resin and membrane technology will give you absolute pure water not only at by measurement of the TDS level, read on your TDS (total dissolved solids) meter, but what is actually removed from the water, such as phosphates and chemical impurities at the smallest level. Not only is SpectraPure known for specialty resins and membranes but another passion of Charles is the development of Peristaltic Dosing Pumps, with applications in the hydroponics and aquarium industries.

Additionally, fulfilling the special needs of fuel cell industry, SpectraPure employees a staff of skilled individuals, with supporting roles in electrical and mechanical engineering, chemistry, manufacturing and administration
