Including filter system and high-performance Hepatitis A Virus filter.
Hepatitis A virus is a tiny pathogen that can enter water when human waste contaminates a supply. Municipal systems normally disinfect water, but treatment interruptions or contamination after treatment can allow problems to occur. Private wells around Watson are also at risk if a well is not properly sealed or sits near potential contamination sources. Because viruses are invisible to the eye, homeowners often only realize there may be an issue when they worry about water safety or see a boil-water advisory.
Viral contamination is not the same as chlorine taste, sediment, or hard water and won’t be fixed by basic polishing filters. Hepatitis A virus spreads by the fecal–oral route and even minute contamination can be meaningful, so testing and a microbial barrier are important. Many Watson residents choose whole-house treatment so water for showers, cooking, teeth brushing and laundry receives consistent protection, whether their home is on a municipal line or a private well.
The most effective single-filter option for hepatitis A virus in a home is a whole-house ultraviolet (UV) disinfection system. UV inactivates microorganisms as water flows through a stainless-steel chamber without chemicals or altering taste. Because viruses are much smaller than particles sediment or carbon filters target, a properly sized and installed UV unit provides reliable treatment and continuous protection at every Watson tap.
For UV to work well, the water entering the chamber should be clear so the light can penetrate; heavy sediment or cloudiness will reduce effectiveness. Many Watson homes pair UV with prefiltration to protect the lamp and quartz sleeve and to maintain steady performance, especially where well water or variable local quality is a concern. Regular maintenance—replacing the UV lamp on schedule and keeping the sleeve clean—keeps disinfection consistent, and Mr. Pure Water can help size and specify the right whole-house UV setup for your plumbing and flow needs.
