Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a broad mix of naturally occurring microorganisms that can show up in household water and plumbing. You may also see this referred to as heterotrophic plate count, a lab method used to gauge overall bacterial growth rather than identify a single pathogen. Elevated results can point to conditions that let bacteria multiply — homeowners often notice musty smells, slimy buildup, or faster biofilm formation on faucets and showerheads when that happens in Thompson plumbing.
Levels of heterotrophic plate count can increase when water sits in pipes, when sediment or organic matter is present, or when biofilm develops inside plumbing. These factors can change taste or odor and indicate your water system needs attention. In Thompson — where humid subtropical weather and seasonal heavy rains can influence well and surface-water quality — a whole-house strategy treats water as it enters your home and helps reduce conditions that allow regrowth downstream.
For whole-home reduction of HPC bacteria, a whole-house ultraviolet (UV) disinfection system is the most effective single filter-style option. UV inactivates microorganisms as water flows through a stainless chamber exposed to a UV lamp, providing real-time control of heterotrophic plate count without chemicals or changing water taste. Properly installed at the point where water enters a Thompson home, a UV system protects every tap, shower, and appliance.
UV works best when the water feeding the unit is clear enough for light to penetrate, since sediment, iron, or cloudiness can shield microbes. That’s why whole-house UV installations often include prefiltration; the UV stage remains the core technology targeting HPC bacteria. Correct sizing for your home’s flow rate and routine lamp and sleeve maintenance keep the system effective. Mr. Pure Water can assess whether your Thompson home needs prefiltration and match a whole-house UV system to your plumbing for better control of heterotrophic plate count.
