Inside, the media sit in layers that blend slightly where they meet. A single 1-micron filter pad at the base supports them and catches fine particles. The sticker on the front gives the size, the SMART level and the part number, which is the fastest way to reorder the right one.\u003c\/p\u003e\n\u003ch3\u003eHow SMART media works\u003c\/h3\u003e\u003ch4\u003eCoconut shell carbon: adsorption\u003c\/h4\u003e\u003cp\u003eActivated carbon is riddled with microscopic pores, and Crystal Quest's acid-washed coconut shell carbon has roughly 1,050 square meters of internal surface in every gram. Organic chemicals such as many VOCs, pesticides and the compounds behind chemical tastes and odors stick to that surface as water passes. Carbon also reacts with free chlorine and converts it to harmless chloride.\u003c\/p\u003e\u003ch4\u003eCatalytic carbon: the chloramine stage\u003c\/h4\u003e\u003cp\u003eMany cities now disinfect with chloramine, a longer-lasting blend of chlorine and ammonia that ordinary carbon handles slowly. Catalytic carbon is coconut carbon with a more reactive surface that breaks chloramine down more effectively. Because every Crystal Quest carbon blend pairs regular and catalytic carbon, you do not need to know which disinfectant your city uses.\u003c\/p\u003e\u003ch4\u003eERA 6500 and ERA 9500: redox\u003c\/h4\u003e\u003cp\u003eEagle Redox Alloy is Crystal Quest's own copper-zinc redox media. As water flows over the granules, electrons move between the metals and dissolved contaminants (oxidation and reduction). ERA 6500 is built for chlorine reduction. ERA 9500 is built for ferrous iron and hydrogen sulfide. Redox chemistry also converts some dissolved metals into forms that stay on the media. The ratio of ERA in the blend is the main difference between Plus, Ultra and Ultimate; it changes between the levels to extend cartridge lifespan.\u003c\/p\u003e\u003ch4\u003eIon-exchange resin: metals\u003c\/h4\u003e\u003cp\u003eA modest amount of potable-grade ion-exchange resin trades harmless ions for dissolved metal ions, adding a metals step that carbon alone does not provide.\u003c\/p\u003e\u003ch4\u003eCeramic and tourmaline media\u003c\/h4\u003e\u003cp\u003eCeramic and tourmaline balls help condition the water and support a balanced, slightly alkaline pH.\u003c\/p\u003e\u003ch4\u003eFilter pad\u003c\/h4\u003e\u003cp\u003eA 1-micron filter pad at the base keeps the media in place and adds particle filtration inside the cartridge.
