Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide mix of naturally occurring microbes that can show up in water and in home plumbing. You may also see this group called heterotrophic plate count, which refers to a lab method used to estimate general bacterial growth rather than identifying a single organism. Elevated HPC results often point to conditions that let bacteria flourish; Fountain homeowners sometimes notice related signs such as musty smells, slimy deposits, or faster biofilm buildup on faucets and showerheads.
Levels of heterotrophic plate count can increase when water sits in pipes, when sediment or organic material is present, or when plumbing encourages biofilm formation. Those circumstances can bring changes in taste or odor alongside broader bacterial activity. Although many heterotrophic bacteria are not known to cause disease, higher HPC counts can indicate that a household water system needs attention. A whole-house strategy in Fountain helps treat the water as it enters your home and reduces the conditions that allow regrowth further down the plumbing.
For whole-home reduction of HPC bacteria, a whole-house ultraviolet (UV) disinfection system is generally the single most effective filter-style option. UV inactivates microorganisms as water flows through a stainless chamber exposed to a UV lamp, providing real-time treatment without adding chemicals or altering taste. When installed where water enters a Fountain house, a UV system protects every tap, shower, and appliance from heterotrophic plate count concerns.
To ensure UV works reliably, the water feeding the unit must be clear enough for the light to reach microbes—heavy sediment, iron, or turbidity can shield organisms. That’s why many whole-house installations pair UV with prefiltration; the UV stage remains the core technology targeting microorganisms like HPC bacteria. Proper sizing for your home’s flow rate and scheduled lamp and sleeve maintenance keep performance steady. Mr. Pure Water can evaluate Fountain homes and recommend the right whole-house UV setup and prefilters to help control heterotrophic plate count at the source.
