Including filter system and high-performance Shigella filter.
Shigella is a bacterium that can enter drinking water when human waste contaminates pipes — for example through cross-connections, backflow, or breaks in the distribution system. Because only a small exposure can cause illness, residents in Blocker treat any notice about Shigella seriously. Even if your community uses municipal treatment, problems can develop between the plant and your tap; installing whole-house protection helps keep water quality consistent throughout your home.
Worries about Shigella in household water most often follow a boil-water advisory, plumbing incident, or wider contamination alert. Bacterial contamination isn’t visible or detectable by taste or smell, so many Blocker families prefer a clear, proactive plan for protection where water enters the house. For homeowners in Florida seeking extra peace of mind, addressing microbial threats at the whole-house level is a practical and effective step.
For Shigella, the single most effective whole-house option is a UV water disinfection system. UV systems expose microorganisms to ultraviolet light at the proper intensity to stop bacteria from reproducing. This chemical-free solution treats all water coming into the home rather than just a single faucet, and when sized correctly for your flow rate it delivers reliable protection against bacteria like Shigella.
A UV system performs best when the incoming water is clear enough for ultraviolet light to penetrate, so many homes in and around Blocker pair UV with prefiltration to remove sediment and cloudiness that can hide microbes. The UV chamber on the main line is the primary device for Shigella control, and ongoing effectiveness depends on proper sizing, a stable power supply, and routine lamp replacement. Mr. Pure Water can help match a whole-house UV setup to your plumbing and water conditions.
