Crown Water Filter Series

Introducing the New AIO Ultra Ceramic with Metalgon™ Filter - The Best Filter for Fluoride Reduction

The NEW AIO Ultra Ceramic water filter with Metalgon™ combines our class leading ceramic micro porous outer shell with our Metalgon™ core block technology. The ceramic shell and our Metalgon™ block core combine mechanical filtration and physical adsorption processes to reduce a wide variety of drinking water contaminants of both aesthetic and health concerns. The contaminant reduction claims with this new technology have been tested by several laboratories to meet ANSI/NSF standards 42, 53 and 401. Metalgon™ is made with the highest quality coconut shell, activated carbon and other special adsorbent materials. Utilizing a unique compression molding manufacturing process, the filter materials are melded into a solid block having a very uniform pore structure that ensures filtration consistency and high performance. The dense pore structure and vast surface area of the compressed carbon and specialty adsorbents is designed to improve taste and odor as well as to reduce chlorine, chloramine, volatile organic compounds, lead, asbestos, and fluoride. *

* MetalgonTM provides the most effective reduction of ALL forms of fluoride, unlike an other filtration media available.

The cleanable outer ceramic shell is designed to remove suspended solids and ultra fine particles. If the flow rate slows down due to accumulated sediment, the ceramic can be brushed off to restore the flow. The Metalgon™ elements have been tested in accordance with ANSI/NSF protocols for removal of fluoride, lead, heavy metals, pharmaceutical compounds, chloramines, chlorine (Class 1), THM's and volatile organic compounds.
