Including filter system and high-performance PFHxA filter.
PFHxA is one of the PFAS chemicals that can be detected in drinking water even at very low concentrations. Local homeowners in Havana often first hear about it from a utility notice, the news, or results from a private test. Because PFHxA is persistent in the environment, many families opt to lower their household exposure rather than only monitor levels. Installing treatment at the main water entry treats every faucet in the house—not just the kitchen sink—so showers, laundry and outdoor taps are covered too.
PFHxA usually won’t change how water looks, smells, or tastes, so you can’t rely on senses to know if it’s present; testing is the only reliable way to find out. When results cause concern, treatment strategies typically use adsorption media that capture PFAS compounds from the flow. It’s also important to pick a system sized for your household’s daily water use so the filter can maintain effective contact time while meeting showers, irrigation and other demands common in Havana homes.
To reduce PFHxA throughout the house, the most effective single filter type is a high-quality activated carbon system—commonly granular activated carbon (GAC) sized to provide adequate contact time. Carbon adsorption is a widely used method for PFAS because the media attracts and holds these compounds as water moves through the bed. A properly sized whole-house GAC unit treats all water entering a Havana residence without the low-flow limits of under-sink point-of-use filters, so everyone in the home benefits.
Whole-house GAC filters are installed at the main water line so PFHxA is addressed before it reaches plumbing and fixtures. Media choice, bed depth and service flow rate affect performance—higher flows shorten contact time and can reduce removal—so routine media replacement is necessary because saturated carbon won’t continue to capture PFHxA effectively. Mr. Pure Water can help Havana homeowners choose the right tank size and carbon volume, install the system, and set up a maintenance plan to keep treatment working reliably.
