Including filter system and high-performance Chlorite filter.
Chlorite is a byproduct that can form when chlorine dioxide is used to disinfect water; it’s different from chlorine but can appear for similar treatment reasons. Because chlorite stays dissolved, it often won’t alter the taste, smell, or clarity of your tap water, so many Marathon homeowners first learn about it from a lab result or utility notice. Whether you’re on municipal service or a private well or cistern here in the Florida Keys, testing is the reliable way to detect it since everyday senses usually won’t pick it up.
If you’d rather limit chlorite exposure for children, seniors, or anyone sensitive in the household, a whole-home solution gives added peace of mind for drinking, cooking, and bathing. Simple pitchers and basic sediment cartridges typically aren’t designed to reduce dissolved byproducts like chlorite. In Marathon—where coastal air and storm exposure can affect plumbing and many properties rely on local systems—a single whole-house system treats water once so every faucet, shower, and appliance receives the same protection.
For chlorite, catalytic carbon is the single most effective whole-house media. Unlike standard activated carbon, catalytic carbon is formulated to encourage surface reactions that reduce certain oxidizing byproducts; because chlorite is dissolved, effective removal depends on proper contact time and the right media. A correctly sized catalytic carbon tank installed on the main line gives the carbon enough exposure to treat water before it flows through the rest of your Marathon home.
A catalytic carbon whole-house system is normally placed after the main shutoff so it protects plumbing, fixtures, and everyday water use without changing your routine. In Marathon properties it’s often paired with a sediment prefilter to guard the carbon bed from sand and debris—helpful where coastal conditions and moderate water hardness can bring sediment into the system. The catalytic carbon stage is the primary barrier for chlorite, and with one properly sized tank you won’t need separate point-of-use devices; Mr. Pure Water can recommend the right configuration for your household flow and water goals.
