Our under-counter water filtration systems represent the ultimate in Foodservice water care. Each cartridge is made with seamless, polymer-lined aluminum; not plastic, like other filtration systems. On the inside, our Micro-Pure precoat filtration technology delivers six times more filtering power and superior chlorine and particulate reduction. Precoat submicron technology reduces dirt and particles as small as 1/2 micron ((0,0005 mm) in size. In fact, even our most affordable filtration system helps safeguard you and your family against harmful contaminants such as lead, cysts and asbestos.Certified under NSF/ANSI Standards, TUV and WRAS.
