Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide mix of naturally occurring microorganisms that can live in water and inside 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 a single pathogen. In Viking homes, these results are a useful indicator of conditions that let bacteria multiply; homeowners often notice musty smells, slimy buildup, or faster biofilm formation on faucets and showerheads when such growth is present.
Levels of heterotrophic plate count can climb when water sits in pipes, when sediment or organic material provides food, or when plumbing encourages biofilm to form. Changes in taste or odors can accompany this general bacterial activity, particularly in humid subtropical climates like ours and in homes with hard, mineral-rich water. While many heterotrophic bacteria aren’t known to cause disease, elevated HPC bacteria still signal that your water system could use attention; taking a whole-house view helps treat water as it enters Viking homes and reduces conditions that lead to regrowth downstream.
To reduce HPC bacteria throughout a 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 past a UV lamp, treating water in real time without chemicals or affecting taste. Installed where water enters a Viking home, a UV system protects every tap, shower, and appliance from heterotrophic plate count concerns.
For UV to work reliably the feed water must be clear enough for light to penetrate—heavy sediment, iron, or cloudiness can shield microbes. That’s why many whole-house setups pair UV with prefiltration; the UV stage remains the core technology targeting microorganisms like HPC bacteria. Proper sizing for your home’s flow rate, routine lamp and sleeve maintenance, and consideration of Viking’s typically hard, mineral-rich water help keep performance steady. Mr. Pure Water can assess your plumbing and recommend the right whole-house UV system and prefiltration to better control heterotrophic plate count at the source.
