Including filter system and high-performance Chromium-6 filter.
Chromium-6, sometimes called hexavalent chromium, is a dissolved form of chromium that can be present in tap water without any noticeable taste, smell, or color. Many Cox homeowners only become aware of it after reviewing a water quality report or having their water tested. It can enter drinking water through industrial activities, certain manufacturing processes, or from contact with chromium-containing materials, so understanding how it behaves and how it’s typically treated can give you more confidence at every tap in your home.
Because chromium-6 stays dissolved, standard sediment or basic carbon filters used for chlorine taste and particles won’t reliably remove it. Treating hexavalent chromium calls for media and systems designed to target dissolved contaminants rather than just trapped solids. For Cox households, a whole-house solution is often the best way to reduce exposure throughout showers, sinks, and appliances rather than relying on a single point-of-use filter at one faucet.
For whole-home reduction of chromium-6, the single most commonly used filter type is a catalytic activated carbon system formulated specifically for chromium reduction. This specialized carbon is engineered to help convert chromium-6 into a form the media can capture as water passes through, while also delivering the everyday benefits homeowners expect from carbon filtration. The important distinction is choosing carbon media selected for chromium-6 performance, not just standard taste-and-odor carbon.
In a correctly sized whole-house catalytic carbon system, contact time and flow rate are just as important as the media itself. Mr. Pure Water configures systems for Cox homes so the filter provides sufficient capacity and exposure time to address dissolved contaminants, including chromium-6, right at the point of entry. That protects every bathroom, kitchen, and laundry line without adding daily maintenance complexity, making a whole-house catalytic carbon setup a practical, set-it-and-forget-it choice for many homeowners.
