Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide group of naturally occurring microbes that can show up in household water and plumbing. You may also see this reported as heterotrophic plate count, a lab method used to estimate overall bacterial growth rather than identify a single pathogen. In Boyd homes, these results can indicate conditions where bacteria are multiplying—homeowners sometimes spot musty odors, slimy buildup, or faster biofilm formation in fixtures like showerheads and faucets when general bacterial activity is present.
Levels of heterotrophic plate count tend to increase when water sits in pipes, when sediment is available as a food source, or when plumbing allows biofilm to form. That bacterial activity can bring changes in taste or odor, particularly if organic material is present. While many heterotrophic bacteria aren’t known to cause disease, elevated HPC bacteria signal that a water system—whether in an older Boyd house or a newer build—could benefit from attention. Treating the water as it enters the home helps reduce the conditions that allow regrowth further downstream.
A whole-house ultraviolet (UV) disinfection system is generally the most effective single filter-style option for reducing HPC bacteria throughout the home. UV inactivates microorganisms as water flows through a stainless chamber exposed to a UV lamp, treating water in real time without adding chemicals or altering taste. When installed where water enters a Boyd residence, a properly sized UV unit provides protection to every tap, shower, and appliance in the house.
For UV to perform reliably, the water feeding the unit must be clear enough for light to reach microbes—heavy sediment, iron, or cloudiness can block UV penetration. That’s why many whole-house setups combine UV with prefiltration, although the UV stage remains the core technology for targeting microorganisms like HPC bacteria. Correct sizing for your home’s flow rate and routine lamp and sleeve maintenance keep the system working well; Mr. Pure Water can help Boyd homeowners choose and install the right whole-house UV system for effective heterotrophic plate count control.
