Our Coconut carbon blocks are manufactured with a high purity Coconut Shell Activated Carbon. With a high chlorine reduction, great dirt-holding capacity, and greatly reduced carbon fines, you will soon make our Carbon Blocks your preferred choice! These are ideal for point-of-use (POU) and Reverse Osmosis applications. These cartridges can be used in a wide range of applications such as residential, food services, commercial, and industrial. These Carbon Blocks are great for displacing traditional GAC (Granular Activated Carbon ) and PAC (Powdered Activated Carbon ) filters in application where high chlorine reduction is needed. BENEFITS:Great performance in reducing sediments, color, SOCs (soluble organic compounds) like pesticides, dioxinsDecrease VOCs (volatile organic compounds) such as chloroform and petrochemicalsUniform and solid media structureDo not exhibit problems such as channeling, fluidizing, bypassing, and the release of carbon fines.NSF-42 approved and made of FDA-compliant materials. The filters media is manufactured from acid washed high purity coconut-based activated carbon. A combination of modern manufacturing processes and choice of high quality materials provides High Quality Coconut Shell Filters the ability to effectively reduce taste and odor from water through adsorption of the compounds that cause problems.CONSTRUCTION MATERIALSFilter Media: Acid-washed coconut-based carbonOuter Wrap: PolypropyleneInner Wrap: polypropyleneNetting: PolypropyleneEnd Caps: PolypropyleneAdhesive (end cap): Ethylene Vinyl Acetate (EVA)Gaskets (O-ring): Polyisoprene (natural rubber, NR)Temperature Rating: 40 - 125 degrees F
