Including filter system and high-performance PFHpA filter.
PFHpA is one of the PFAS chemicals that can be present in drinking water and leave homeowners wondering about tap safety. Because PFAS are persistent in the environment, they don’t break down quickly and aren’t removed by basic filtration alone. Even if Bon Ami’s water looks and tastes normal, PFHpA could still be present, so understanding options to limit long-term exposure throughout your home is important for peace of mind.
PFHpA belongs to the larger PFAS family, a group of compounds used in industry and formed over time as related substances degrade. These chemicals behave differently from common contaminants like chlorine or sediment, so they require filter media designed to capture them. For Bon Ami homeowners, treating water at the point it enters the house is a convenient way to protect showers, cooking water, laundry, and every faucet from PFHpA without installing multiple point-of-use units.
For reducing PFHpA in whole-house applications, activated carbon is generally the most effective single-filter choice. Granular activated carbon (GAC) offers extensive surface area that adsorbs many PFAS compounds as water flows through the tank. Because adsorption performance relates to contact time, a correctly sized GAC tank and appropriate flow rate are as crucial as the carbon itself, which is why whole-house systems intended for PFAS prioritize ample media volume over small cartridges.
A whole-house GAC system installed at Bon Ami homes treats water at the point of entry so PFHpA is reduced before it reaches showers, sinks, and appliances. It’s a simple option for homeowners who prefer one system to cover the entire house instead of multiple under-sink filters. As with any adsorption system, the condition of the carbon matters — routine maintenance and timely carbon replacement keep removal consistent, and Mr. Pure Water can help size and service a system to match your household’s water use.
