Residential Filters

Extremely difficult water problems can be corrected with the wide range of filters manufactured by Sterling. If your problem is: acid water, high iron, arsenic, nitrates, sulfates, manganese, rotten egg odor, sediment, or chlorine Sterling has the filter to handle the job. Filter systems are available in sizes that meet the flow rate needed, no matter how big the demand. Most systems do not require a chemical regenerant and use a very limited amount of water to clean the filter media.

OXY3 Series

This filter reduces staining and eliminates odors in water when associated with iron or hydrogen sulfide in limited quantities. Also, it requires no chemicals, and does not have an in-line venturi to plug or adjust, and there are no air compressors or air release valves.

FCF Series

The Iron Pro System is the perfect solution for removing iron from household water without using chemical regenerates. That means no salt, potassium permanganate, chlorine, or any other chemicals to buy or mess with. Instead, this unique system oxidizes iron to create molecules that can be readily captured in filter media.

Our History

Our roots go back to 1934. This was the year that Charlie Sidell started in the water treatment business with his one employee, Emmett Culligan. They manufactured manual water softeners in their Fort Wayne, Indiana facility. In 1967, the new owners Robert and Rudy Wilfong moved the factory to Churubusco, Indiana. This new location provided room to grow in a rural and more wholesome environment to build the business. And grow it did! The business evolved into the largest supplier of water treatment equipment to the plumbing and well supply trade. Today, Sterling offers a complete line of innovative filters, softeners, and reverse osmosis systems. These products are available through licensed plumbers, well drillers, and pump installers nationwide.
