Arsenate, the oxidized form, carries a negative charge at normal drinking water pH. Arsenite, the reduced form common in oxygen-poor groundwater, carries almost no charge. That difference decides how well any arsenic media can catch it.\u003c\/p\u003e\u003ch4\u003eCapture on selective media\u003c\/h4\u003e\u003cp\u003eArsenic-selective media is built with sites that hold arsenate strongly as water flows past. Because arsenate is charged, it is drawn to those sites and held, while the water continues on. Uncharged arsenite has little to hold on to, so it passes far more easily.\u003c\/p\u003e\u003ch4\u003eWhy oxidation and water chemistry matter\u003c\/h4\u003e\u003cp\u003eChlorine converts arsenite to arsenate. On chlorinated city water, most arsenic already arrives in the form the media captures best. On well water without chlorination, some arsenic may be arsenite, and an oxidation step ahead of the media makes treatment far more effective. Other dissolved ions in your water also compete for the same sites, so how long the media lasts depends on your full water chemistry, not just the arsenic number on your report.\u003c\/p\u003e\n\u003ch3\u003eWhat it reduces\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003ePrimary target (printed on the cartridge label):\u003c\/strong\u003e arsenic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot designed to treat:\u003c\/strong\u003e chlorine and chemical tastes, fluoride, nitrate, dissolved solids, or bacteria and viruses.

An \u003ca href=\"https:\/\/crystalquest.com\/products\/arsenic-test\"\u003eArsenic Test\u003c\/a\u003e confirms whether arsenic is present and gives you a baseline to check the treated water against. If your water is from a well and is not chlorinated, or your arsenic is high, talk to a Crystal Quest specialist first: the form of arsenic and the rest of your water chemistry decide the right treatment, and a whole-house or multi-stage approach may fit better than a single point-of-use stage.\u003c\/p\u003e\u003ch3\u003eWhy Crystal Quest\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA dedicated stage, not an afterthought.\u003c\/strong\u003e Arsenic gets its own cartridge and media instead of sharing space in a general-purpose filter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade for our systems.\u003c\/strong\u003e Crystal Quest lists this cartridge as the optional arsenic stage for its under-sink RO, countertop RO and water cooler systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraight answers about your water.\u003c\/strong\u003e We tell you what this cartridge is built for, what affects its life and when to call us before buying.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver 1,000,000 people served since 1994.\u003c\/strong\u003e Crystal Quest builds under ISO 9001 quality management, has made water filtration in the USA for over 30 years and offers lifetime support by phone, email or chat.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhere it fits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThunder under-sink RO systems:\u003c\/strong\u003e listed as the optional arsenic cartridge, CQE-RC-04062, on Thunder system pages such as the \u003ca href=\"https:\/\/crystalquest.com\/products\/reverse-osmosis-under-sink-water-filter-1000c\"\u003eThunder 1000C\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe \u003ca href=\"https:\/\/crystalquest.com\/products\/countertop-reverse-osmosis-water-filters\"\u003eCountertop Reverse Osmosis System\u003c\/a\u003e:\u003c\/strong\u003e listed as its optional arsenic stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottleless water coolers:\u003c\/strong\u003e the optional Water Cooler\/Reverse Osmosis Arsenic cartridge in the water cooler manual.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerator and ice maker lines:\u003c\/strong\u003e plumbed inline on the supply tubing.
