Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a broad set of naturally occurring microbes that can show up in household water and plumbing. You may also see the term heterotrophic plate count, which refers to a lab method used to estimate overall bacterial growth rather than identifying one specific pathogen. High counts can indicate conditions that let bacteria multiply—homeowners in Koerber sometimes notice this as musty smells, slippery buildup, or faster biofilm formation on fixtures and showerheads.
Levels measured by heterotrophic plate count tend to increase when water sits in pipes, when sediment or organic material is present, or when plumbing allows biofilm to develop. These situations can bring changes in taste or odor alongside general bacterial activity. While many heterotrophic bacteria aren’t known to cause disease, elevated HPC bacteria are a sign your household water system may need attention. Treating water at the point it enters your Koerber home helps reduce factors that allow regrowth downstream.
To reduce HPC bacteria throughout the house, a whole-house ultraviolet (UV) disinfection system is generally the most effective single filter-style option. 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 Koerber home, UV protection covers every tap, shower, and appliance.
For UV to work reliably, the water feeding the unit must be clear enough for light to penetrate because heavy sediment, iron, or cloudiness can shield microbes. That’s why whole-house UV setups are often paired with prefiltration, while the UV stage remains the core technology targeting microorganisms like HPC bacteria. Proper sizing for your home’s flow rate and routine lamp and sleeve maintenance keep the system performing; Mr. Pure Water can help Koerber homeowners select and size a whole-house UV system to control heterotrophic plate count at the source.
