Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a broad mix of naturally occurring microbes that can show up in household water and plumbing; you may also see them called heterotrophic plate count when labs report overall bacterial growth. Those test results don’t identify a single pathogen but can indicate conditions where bacteria are multiplying. In Pace homes this can present as musty smells, slippery or slimy buildup in fixtures, or faster biofilm accumulation on showerheads and faucets.
Heterotrophic plate count readings can climb when water lingers in pipes, when sediment or organic material is present, or when plumbing allows biofilm to form. Changes in taste or odor often accompany this kind of general bacterial activity. While many heterotrophic bacteria aren’t known to cause illness, higher HPC bacteria levels are a sign the water system should be checked. A whole-house strategy treats the water entering a Pace residence and helps reduce conditions that allow regrowth downstream.
To reduce HPC bacteria throughout the house, a whole-house ultraviolet (UV) disinfection system is usually 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 chemicals or altering taste. Installed where water enters the home, a UV system protects every tap, shower, and appliance in your Pace property.
For UV to work reliably, the water feeding the unit needs to be clear enough for the light to reach microbes — heavy sediment, iron, or cloudiness can block the lamp’s effect. That’s why UV is often used with prefiltration, while the UV stage remains the core technology targeting HPC bacteria. Proper sizing for your home’s flow rate plus regular lamp and sleeve maintenance keep performance steady; Mr. Pure Water can help Pace homeowners choose and install the right whole-house UV setup to better control heterotrophic plate count at the source.
