Including filter system and high-performance Pseudomonas filter.
Pseudomonas is a group of bacteria that can appear in household water when conditions allow it to persist and grow. One species, Pseudomonas aeruginosa, commonly forms slimy biofilms on damp surfaces and inside plumbing parts, making it harder to rinse away than many other microbes. In Havana homes you may notice recurring odors, a filmy coating, or buildup around faucets, showerheads, and aerators where water sits or flow is low.
Because Pseudomonas often lives in biofilms, treating it isn’t always a one-time fix. The bacteria can hide in faucet screens, hoses, humid spaces, and plumbing areas with low disinfectant residual. Homeowners with sensitive skin or anyone wanting cleaner bathing water in Havana may choose a whole-house strategy to reduce exposure at every tap and limit recurrence in fixtures and pipes.
For whole-house protection against Pseudomonas, the most effective single-filter solution is a UV (ultraviolet) disinfection system installed at the home’s main water entrance. UV inactivates microbes as water passes through the chamber without adding chemicals, making it a good match for bacteria like Pseudomonas aeruginosa. Because UV treats all incoming water, it helps reduce exposure during showering, brushing teeth, and washing — but performance depends on water clarity and proper sizing to your home’s flow needs.
A UV unit is usually paired with a sediment prefilter to prevent particles from shading organisms from the light; the UV lamp itself is the core microbial control. With correct installation and regular lamp and sleeve maintenance, UV gives consistent whole-house treatment without altering taste or odor. After adding UV, cleaning or replacing aerators and showerheads can help address any biofilm that formed earlier — Mr. Pure Water can recommend a UV setup sized for Havana homes so treated water reaches every bathroom, kitchen, and hose bib.
