It drops into the housing of your Crystal Quest shower filter, seals against two O-rings, and the shower head threads on as usual. Nothing about your shower routine changes except the water.\u003c\/p\u003e\u003ch3\u003eHow a shower filter cartridge works\u003c\/h3\u003e\u003ch4\u003eRedox media: chemistry that likes hot water\u003c\/h4\u003e\u003cp\u003eERA (Eagle Redox Alloy) is Crystal Quest's own high-purity copper-zinc granular media. As water flows over the granules, electrons move between the metals and the dissolved contaminants. This oxidation-reduction reaction, redox for short, is how the media reduces chlorine. ERA 6500 is the chlorine specialist. ERA 9500 targets iron and hydrogen sulfide, the gas behind a rotten-egg smell. Because redox is a chemical reaction rather than adsorption, it does not depend on cool water, and Crystal Quest rates both media for influent water from 35°F to 212°F.\u003c\/p\u003e\u003ch4\u003eWhy carbon alone is not enough in a shower\u003c\/h4\u003e\u003cp\u003eActivated carbon works by adsorption: contaminants are attracted to the carbon and held on its huge internal surface. Adsorption needs contact time, and a shower gives very little. Water moves through this small cartridge at shower flow and is out of the head almost instantly. That is why a good shower filter leads with redox media and uses carbon as a partner, not the other way around.\u003c\/p\u003e\u003ch4\u003eCoconut shell carbon: the polisher\u003c\/h4\u003e\u003cp\u003eThe coconut shell granular activated carbon (GAC) in the blend picks up chlorine, chloramines and organic compounds that make it past the redox stage, so the water that reaches your hair and skin is cleaner and smells fresher.\u003c\/p\u003e\u003ch4\u003eCeramic media: conditioning\u003c\/h4\u003e\u003cp\u003eCeramic media rounds out the blend, conditioning the water and helping balance its pH.\u003c\/p\u003e\u003ch4\u003eWhy it reverses\u003c\/h4\u003e\u003cp\u003eWater tends to find the easiest path through any media bed. Over time that path, called a channel, carries more water than the rest of the media. Turning the cartridge around sends water the other way, back-flushing the media and putting the whole bed back to work.\u003c\/p\u003e\u003ch3\u003eWhat it targets\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003ePrimary target (independently lab tested):\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eChlorine, the source of the bleach smell in a hot shower\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAlso targeted by the media blend:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eChloramines\u003c\/li\u003e\n\u003cli\u003eHydrogen sulfide and sulfur odor\u003c\/li\u003e\n\u003cli\u003eVolatile organic compounds (VOCs) and trihalomethanes (THMs)\u003c\/li\u003e\n\u003cli\u003ePesticides\u003c\/li\u003e\n\u003cli\u003eDirt and sediment held back by the stainless steel screens\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNot designed to treat:\u003c\/strong\u003e hardness minerals (it is not a water softener), bacteria and viruses, fluoride, nitrate or total dissolved solids.
