Sterling Iron Filtration
Sterling Water Treatment is a true manufacturer not merely an assembler. A wide range of components are made in our Indiana facility. Our design team has focused on new products that are far more efficient, easier to service and provide more value to the consumer. As the leading supplier to the plumbing and well supply industries, Sterling products are sold only by licensed contractors in North America. Sterling began manufacturing in 1934. Most of the time since then, the company has been under the same family ownership.
