Including filter system and high-performance Hepatitis A Virus filter.
Hepatitis A virus is a tiny pathogen that can enter drinking water when human waste contaminates a supply. Even though community systems use disinfection, breaks in treatment or contamination after treatment can allow viruses through, and private wells around Havana can be at risk if a well cap or seal is compromised or nearby surface contamination reaches the well. Because you can’t see a virus, worries about water safety are often what alert homeowners first — testing is the only way to know for sure.
Microbial risks like hepatitis A virus aren’t the same as common water complaints such as chlorine taste, sediment, or hard water — typical polishing filters don’t reliably stop viruses. Hepatitis A spreads by the fecal‑oral route and even small amounts of contamination can matter, so testing and a dedicated microbial barrier are important. Many Havana homeowners choose whole‑house protection so water used for bathing, cooking, brushing teeth and laundry is treated the same throughout the house.
The most effective single‑filter option for hepatitis A virus in a home is a whole‑house ultraviolet (UV) disinfection system. UV inactivates microbes as water flows through a stainless steel chamber, without adding chemicals or altering taste. Because viruses are much smaller than what sediment or carbon filters capture, a properly sized and installed UV unit offers dependable viral treatment and is a practical choice for Havana households seeking continuous protection at every tap.
For UV to work reliably, the water entering the chamber needs to be clear so the light can penetrate; heavy sediment or cloudiness reduces effectiveness. That’s why many homes in and around Havana pair UV with prefiltration to protect the unit and preserve performance. Regular upkeep — replacing the UV lamp on schedule and keeping the quartz sleeve clean — keeps disinfection consistent. Mr. Pure Water can help recommend the right whole‑house UV system sized for your plumbing, flow demands, and local water conditions.
