Manufactured in the USA
Every QMP product is built at our facility in Valencia, California. No overseas assembly lines, no mystery supply chains, and full traceability from raw material to the finished system sitting under your sink.
33+ Years of Engineering Expertise
QMP has been in this business since 1994, and our founder Freddy Vidal holds multiple U.S. patents in water filtration technology. That kind of know-how only comes from decades spent on the factory floor.
Trusted by Major Brands
Large, well established companies have partnered with QMP over the years. When organizations of that scale choose a manufacturing partner, they don’t cut corners on quality and that same standard goes into every system we build.
Complete In-House Production
CNC machining, injection molding, assembly, and testing all happen under one roof at our Valencia facility. We don’t outsource the critical steps, which means tighter quality control on every unit we ship. Whether serving residential homeowners or small businesses, we maintain consistent standards from production to delivery.
Built for Homes & Businesses
Our reverse osmosis systems are designed for both residential households and small businesses that need reliable, high quality water filtration. They fit standard under sink spaces, are easy to install, and provide a practical solution for families, offices, cafés, and other everyday business environments without the complexity of large commercial systems.
Components You Can Trust
QMP doesn’t just make complete systems. We also manufacture the housings, fittings, faucets, and cartridges that go inside them, so quality stays consistent from the first component to the final product.
