Including filter system and high-performance Shigella filter.
Shigella is a bacterium that can enter household water when human waste contaminates pipes—often through backflow, cross-connections, or breaks in the distribution system. Because only a small exposure can cause illness, homeowners in Havana take any notice about Shigella seriously. Even if your water is treated by a utility, problems can occur between the plant and your tap, so many local families choose a whole-house approach to keep water quality consistent throughout their home.
Worries about Shigella often surface after a boil-water advisory, a plumbing incident, or a wider contamination alert. Bacterial contamination isn’t something you can reliably taste or smell, which makes it harder to detect in Havana households. That uncertainty leads many homeowners to plan for protection at the point where water enters the house; addressing microbial risks with whole-house treatment can provide practical peace of mind for families here.
For controlling Shigella, the most effective single whole-house option is a UV water disinfection system. UV disinfects by exposing microorganisms to a specific intensity of ultraviolet light that stops bacteria from reproducing. Because it’s chemical-free and treats all incoming water, a whole-home UV unit protects every faucet and appliance rather than relying on individual filters. When sized to your home’s flow rate, UV offers strong defense against bacteria such as Shigella.
A UV chamber performs best when water is clear enough for the light to reach microbes, so many Havana homeowners pair it with a prefilter to remove sediment and cloudiness that can shield bacteria. The UV device itself is installed on the main water line, and reliable performance depends on correct sizing, a steady power supply, and replacing the lamp on the manufacturer’s schedule. Mr. Pure Water can help Havana residents choose and size a whole-house UV system based on your plumbing and water conditions.
