One of our most popular filtration systems for municipal city water is the Patriot Pure Backwashing Filter. This unit comes in two sizes depending on contaminant levels and flow rates. This system is an automatic backwashing filter that has multiple medias in the media tank which are separated by a midplate. The media in this tank consists of a catalytic granular activated carbon for removal of chlorine, chloramines, and other volatile organic chemicals. As well as a KDF blend. KDF is known to be bacteriostatic as well as being effective in lead removal. The control valve is user friendly and has a great warranty as well.
