Filtration Media MetalEase-AS™ (Advanced Structure)
Heavy Metals Removal Media
MetalEase-AS™ (P/N METALEASE AS) is a highly processed version of our standard MetalEase™ oxidation technology. MetalEase-AS (Advanced Structure) works on a similar principle of bringing dissolved metals out of solution, and the metals have an affinity for the media. Most MetalEase-AS filter applications require no chemical regeneration. This product is available with NSF/ANSI Standard 61 Certification (P/N METALEASE AS NSF 61).
MetalEase-AS is capable of removing high levels of iron, hydrogen sulfide, and other metals such as lead, copper, arsenic, and manganese. The media first brings the metals out of solution into a solid form and then adheres the particle in the MetalEase-AS media bed.

MetalEase-AS is designed to be used in place of traditional forms of iron treatment and can be installed on either well or municipal water supplies. It is used in cartridge form and as a backwashable media bed. It can be used as a stand-alone unit or as the perfect companion to softeners, RO systems, carbon filters, etc.

MetalEase-AS is capable of removing contaminants, but tends to work better in some geographic areas than others, depending on the levels of TDS or heme iron (organics) in the local water supplies.
For safety and handling purposes, avoid contact with eyes, skin, and clothing. Avoid breathing the dust and always use adequate ventilation. Wash thoroughly after handling. Keep away from heat and easily oxidizable materials.
