Filtrine’s Strengths


Since 1901 when George Kneuper patented a new filter medium, Filtrine’s water purification line has also grown to include activated carbon treatment for taste and odor removal, and ultraviolet sterilizers to kill bacteria and other micro-organisms. Filtrine is also proud of its reputation around the world as a problem solver in the cooling of liquids. Prior to the advent of electric refrigeration, its water filters and ice coolers were installed around the country for both drinking water and process chilling applications.

Customization and Durability

Because of Filtrine’s high quality and elegant stainless steel and bronze drinking fountains, its drinking water systems have been installed in the White House, the United Nations Building, National Gallery of Art, Apple flagship stores and in thousands of other fine public and commercial buildings around the world. Filtrine’s drinking water systems which include drinking fountains, bottle filling stations, chillers, purifiers, filters and sterilizers are the benchmark for the industry and are specified for the best projects around the world, often outlasting the buildings they were installed in.

Filtrine’s chillers are used to cool medical equipment such as MRIs, CT scanners, cyclotrons, proton therapy systems, PET Scan, PET/CT and linear accelerators as well as many custom applications for industry and institutions. The company supplies the leaders in the medical equipment industry including Elekta, GE Healthcare, Hitachi Medical Systems, Mevion Medical Systems, Philips Healthcare, Siemens, Siemens Petnet Solutions, Varian Medical Systems and more, throughout the world. Filtrine’s OSP models have been put through rigorous testing and have been pre-approved for OSPD special seismic certification by the State of California. In addition for over 70 years, the bakery industry has relied on Filtrine’s unique storage design which delivers batches of consistent 34 degree water into a dough mixer without the danger of freeze-up. E.T. Oakes and Magna Mixer are some of their most loyal customers.
