Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a broad group of naturally occurring microorganisms that can live in water and inside plumbing. You may also see the term heterotrophic plate count, a lab method used to estimate overall bacterial growth rather than identifying a single pathogen. These measures can indicate conditions that allow bacteria to multiply; homeowners in Footman sometimes notice related signs such as musty smells, slimy deposits, or faster biofilm buildup on faucet aerators and showerheads.
Heterotrophic plate count can increase when water stands in pipes, when sediment or organic matter is present, or when plumbing surfaces permit biofilm to form. Changes in taste or odor often accompany this kind of general bacterial activity. Although many heterotrophic bacteria aren’t known to cause illness, elevated HPC bacteria suggest your household water system could use attention. In Footman, a whole-house strategy treats incoming water and reduces the conditions that allow regrowth further down the plumbing.
The most effective single filter-style option for reducing HPC bacteria throughout a home is a whole-house ultraviolet (UV) disinfection system. UV inactivates microorganisms as water flows through a stainless chamber exposed to a UV lamp, providing real-time treatment without chemicals or altering taste. Installed at the point where water enters a Footman home, a properly sized UV unit protects every tap, shower, and appliance from heterotrophic plate count concerns.
For UV to work reliably, the water feeding the unit must be clear enough for light to penetrate—heavy sediment, iron, or cloudiness can shield microbes from the lamp. That’s why whole-house UV is often paired with prefiltration, while the UV stage remains the core technology targeting microorganisms like HPC bacteria. Correct sizing for your home’s flow rate plus regular lamp and sleeve maintenance keeps performance steady. Mr. Pure Water can help Footman homeowners choose and install a whole-house UV system suited to their plumbing so heterotrophic plate count is better controlled at the source.
