The pleated sediment cartridge uses cellulose media wrapped around a polypropylene core, with vinyl plastisol end caps. The SMART cartridge combines coconut shell carbon, catalytic carbon, redox alloy, ion-exchange resin, ceramic and tourmaline media in one cartridge. The carbon block is a solid block of acid-washed coconut shell activated carbon rated at 5 microns. Each is the same part listed in Crystal Quest's own replacement tables, not a generic look-alike.\u003c\/p\u003e\u003ch3\u003eHow the three stages protect your RO membrane\u003c\/h3\u003e\u003ch4\u003eStage 1: sediment\u003c\/h4\u003e\u003cp\u003eThe pleats give the cellulose media a large surface, so it holds a lot of dirt while filtering to 5 microns. It removes sand, silt and rust particles that would otherwise plug the membrane's feed channels and load the stages after it.\u003c\/p\u003e\u003ch4\u003eStage 2: SMART\u003c\/h4\u003e\u003cp\u003eSeveral media do different jobs at once. Catalytic carbon targets chloramine, which standard carbon reduces less effectively. Coconut shell carbon adsorbs chlorine and organic chemicals, while the redox alloy and ion-exchange media work on metals.\u003c\/p\u003e\u003ch4\u003eStage 3: carbon block\u003c\/h4\u003e\u003cp\u003eThe tightly bonded coconut carbon block gives water a long contact time with the carbon, polishing out remaining chlorine, taste and odor compounds, and fine particles down to 5 microns. It is the last guard before the membrane.\u003c\/p\u003e\u003ch4\u003eWhy chlorine removal matters so much\u003c\/h4\u003e\u003cp\u003eThe thin-film composite membrane in a Crystal Quest whole house RO system tolerates less than 1 ppm chlorine. Chlorine that slips past spent pre-filters slowly damages the membrane surface, and that damage does not reverse. Changing pre-filters on time is how you protect the membrane and the system around it.\u003c\/p\u003e\n\u003ch3\u003eWhat it reduces\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003ePrimary targets\u003c\/strong\u003e (the jobs that protect your RO membrane):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSediment and suspended particles down to 5 microns, such as sand, silt and rust particles\u003c\/li\u003e\n\u003cli\u003eChlorine and chloramine; chlorine that reaches the thin-film composite membrane damages it, and that damage does not reverse\u003c\/li\u003e\n\u003cli\u003eChlorine taste and odor\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAlso reduced\u003c\/strong\u003e by the SMART and carbon media: volatile organic compounds and other organic chemicals, and a range of metals.
