Including filter system and high-performance Shigella filter.
Shigella is a bacterium that can enter household water when human waste contaminates distribution lines through cross-connections, backflow, or breaks in the system. Because it only takes a small exposure to cause illness, Bertha homeowners tend to treat any Shigella advisory seriously. Even if your community relies on municipal treatment, problems can occur between the plant and your tap, so many local families choose a whole-house strategy to keep water quality consistent throughout their home.
Questions about Shigella in household water often arise after a boil-water advisory, a notable plumbing event, or a broader contamination notice. Bacterial contamination isn’t something you can reliably detect by sight or smell, which makes planning important for Bertha residents. Given our humid subtropical climate and the hard, limestone-influenced groundwater common inland, many homeowners prefer treating incoming water at the whole-house level to add a dependable layer of microbial protection.
For Shigella, the most effective single whole-house option is a UV water disinfection system. UV inactivates microorganisms by exposing them to ultraviolet light at a precise intensity so they can’t reproduce. This chemical-free method treats all water entering the home rather than just a single faucet, and when the unit is sized correctly for your flow rate it provides strong defense against bacteria like Shigella.
UV systems perform best when water is clear enough for the light to penetrate, so Bertha homes—where hard water and scale from limestone-influenced groundwater are common—often pair UV with prefiltration to remove sediment and cloudiness that can hide microbes. The UV chamber on the main line is the device that controls Shigella, and reliable results depend on correct sizing, a steady power supply, and routine lamp replacement. Mr. Pure Water can help match a whole-house UV setup to your Bertha plumbing and water conditions.
