Including filter system and high-performance Enterococci filter.
Enterococci are bacteria that can appear in household water when sources are affected by environmental contamination. Because they’re microscopic, you won’t detect them by taste, smell, or sight — water can look clear and still be a problem. These organisms are often used as indicators of possible fecal contamination, which is why they’re important to consider for home water safety. If your Stern property uses a private well, regular testing is especially important to know what’s in your water.
For Stern homeowners, the objective is straightforward: keep bacteria out of the water you drink, cook with, and bathe in. Enterococci can get into household plumbing via events like surface water intrusion, well flooding, damaged well caps, or plumbing conditions that allow contaminants to enter. Even short-term incidents can leave you uncertain about everyday water use throughout the house. Treating water where it enters the home — at the point of entry — is an effective way to protect every tap and restore confidence in your water.
The single most effective filter type for removing enterococci is a whole-house ultraviolet (UV) disinfection system installed on the main water line. Rather than capturing bacteria in media, UV inactivates microorganisms as water flows through the lamp chamber, preventing them from reproducing. Because a point-of-entry UV system treats all incoming water, it safeguards every faucet, shower, and appliance in your Stern home instead of just a single outlet, making it a practical whole-home response when bacterial contamination is a concern.
For reliable UV performance, your water must be clear enough for the light to penetrate — heavy sediment or turbidity can reduce effectiveness. Many homeowners pair the UV system with a prefilter to remove grit and cloudiness, while the UV unit remains the primary treatment for enterococci. Properly sizing the unit for your home’s flow rate and keeping the lamp and sleeve maintained will help ensure consistent disinfection, giving continuous, chemical-free protection at the point of entry.
