Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds people look for when checking persistent, hard-to-remove contaminants in household water. It can enter supplies through industrial uses and the breakdown of related fluorinated chemicals, and it’s known to persist rather than break down quickly. In Glass many homeowners first hear about PFUnA from a utility notice, local coverage, or private testing. If you’re worried, focus on treatment options proven to reduce PFAS specifically rather than relying on general-purpose filters.
Because PFUnA is usually at very low concentrations, it won’t give off taste, smell, or visible signs, which makes testing important to know what’s really coming from your tap in Glass. PFAS like PFUnA behave differently than chlorine, sediment, or hardness, so standard cartridge filters or softeners may not address them. For many Glass households, a whole-house solution is a practical way to lower exposure during drinking, cooking, showering and everyday use throughout the home.
For whole-house reduction of PFUnA, a quality granular activated carbon (GAC) filter is widely used as the most effective single-filter residential option. GAC media offers a very large surface area that adsorbs many organic compounds, including various PFAS. Performance against PFUnA depends on choosing the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates—so a properly sized whole-house carbon tank typically outperforms small, fast-flow cartridges in a Glass home.
Mr. Pure Water installs whole-house GAC systems at the main water entry so treated water reaches every tap and appliance in Glass residences. Systems are sized to match household water use to prevent short contact times that reduce PFAS capture. As with any adsorption media, the carbon must be serviced and replaced on schedule to maintain removal efficiency as the media becomes loaded. If you have recent test results for your Glass property, we’ll use them to recommend the right GAC configuration for PFUnA reduction.
