Including filter system and high-performance Enterococci filter.
Enterococci are bacteria that may show up in water when environmental contamination affects sources. You won’t taste or see them—water can look crystal clear yet still be affected—so testing is the only reliable way to know what’s present. Because these organisms are often used as indicators of possible fecal contamination, they’re important to consider for your household water. If your Key West home uses a private well or has experienced storm surge or flooding during hurricane season, routine lab testing is especially important to make sure your water is safe.
As a homeowner, you want safe water for drinking, cooking and bathing across every faucet. Enterococci can get into household plumbing after surface water intrusion, well flooding, a damaged well cap, or other vulnerabilities in the system. In the Keys, salt air and coastal storms can increase risks to storage and pipe integrity, so even short-lived contamination episodes can leave you uncertain about everyday water use. Treating the water where it enters your Old Town or New Town house helps protect showers, sinks and appliances throughout the property.
The most effective single filter for addressing enterococci is a whole-house ultraviolet (UV) disinfection system installed on the main service line. Unlike a media filter that captures particles, UV inactivates microorganisms as water flows past the lamp chamber, preventing them from reproducing. Because a point-of-entry UV system treats all incoming water, it shields every faucet, shower and appliance in your Key West home rather than protecting only one fixture—making it a practical choice when bacterial contamination is a concern.
UV disinfection performs best when the incoming water is clear enough for the light to penetrate, so homeowners often pair a prefilter to remove sediment and turbidity from moderately hard Key West water. The UV unit remains the primary treatment aimed at enterococci; correct sizing for your household flow rate and routine lamp and sleeve maintenance are essential to consistent disinfection. With a properly designed system, UV offers continuous, chemical-free protection at the point of entry for homes across Monroe County.
