Including filter system and high-performance Cotinine filter.
Cotinine is a breakdown product of nicotine that can enter the water cycle when tobacco residues reach wastewater and surface waters. While it’s often mentioned in clinical exposure testing, it can also serve as an environmental marker for tobacco-related contaminants. Franjo homeowners who spot cotinine on water reports or who worry about trace substances in treated water commonly want to know how it behaves and what they can do to reduce it at the tap.
When present, cotinine is usually at very low, dissolved concentrations and won’t necessarily change water taste, smell, or clarity. That means basic sediment filters and many pitcher-style filters won’t reliably remove it, because those systems are meant for particulates or larger molecules. For families in Franjo seeking broader protection from trace organic contaminants, a whole-house treatment strategy provides coverage for every faucet, shower and appliance.
To address cotinine throughout a home, a whole-house activated carbon system is commonly the most effective single-filter choice. Options like catalytic carbon or high-quality granular activated carbon are designed to adsorb dissolved organic compounds, including nicotine byproducts such as cotinine. Installed at the point where water enters your Franjo home, a carbon tank captures these molecules before water reaches sinks, showers and laundry.
Performance depends on contact time and the amount of carbon in the tank, so correctly sizing the system matters to maintain flow and consistent removal at typical household demand. A properly balanced setup delivers strong adsorption without sacrificing water pressure or volume, and routine media replacement restores capacity as carbon becomes spent. Mr. Pure Water can evaluate homes in Franjo and recommend the right whole-house carbon system to reduce cotinine exposure across your plumbing.
