Including filter system and high-performance ADONA filter.
ADONA is a synthetic chemical that’s discussed alongside other PFAS chemicals and can turn up in drinking water. Many Key Largo homeowners first hear about it from utility notices, local news, or private well testing — especially in the Florida Keys where households often use storage tanks or treatment setups. ADONA is a distinct compound within the broader PFAS group and addressing it usually means choosing the right treatment for your situation.
Because ADONA is associated with certain industrial uses, it can reach water supplies through environmental releases and remain for long periods. It won’t typically change the smell, taste, or look of water, so testing is the only reliable way to know if it’s present. For residents of Key Largo and surrounding Monroe County communities, a whole-house system is a useful option because it reduces exposure at every tap, including water stored in tanks or treated before use.
The single filter type most commonly chosen to reduce PFAS compounds such as ADONA in whole-house systems is high-capacity activated carbon. Granular activated carbon (GAC) has a very large internal surface area that adsorbs many trace organic contaminants as water moves through the media. In a correctly sized whole-home installation, GAC treats water used for showers, laundry and kitchen taps — important in Key Largo’s humid, coastal climate where plumbing can be more prone to corrosion and homes often rely on treatment equipment. Proper sizing for your household flow rate and water hardness is key to dependable performance.
Typically, a whole-house activated carbon filter is installed where water enters the property so it protects every outlet without changing daily habits. To maintain ADONA removal, the carbon media needs routine replacement based on how much water your household uses and the contaminant load. If your Key Largo home uses well water or storage tanks, adding a sediment prefilter ahead of the carbon helps prevent clogging and channeling of the media. Mr. Pure Water can size and install a whole-house GAC system to match your plumbing, water hardness, and local conditions so ADONA reduction is consistent across the home.
