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’ll also see them called heterotrophic plate count, which is the lab method used to estimate overall bacterial growth rather than identify a single pathogen. High readings often point to conditions that allow bacteria to multiply — things homeowners in Glass may notice include musty smells, slimy buildup in fixtures, or faster biofilm formation on showerheads and faucet screens.
Heterotrophic plate count levels tend to increase when water remains stagnant in pipes, when sediment or organic material is present to feed microbes, or when plumbing encourages biofilm growth. Taste or odor changes can accompany this general bacterial activity. While many heterotrophic bacteria aren’t known to cause illness, elevated HPC bacteria are a sign your household plumbing or incoming water might need attention. A whole-house strategy helps treat water as it enters Glass homes and reduces conditions that allow regrowth further downstream.
A whole-house ultraviolet (UV) disinfection system is generally the most effective single filter-style option for reducing HPC bacteria throughout a home. UV inactivates microorganisms as water flows through a stainless chamber exposed to a UV lamp, treating water in real time without chemicals or altering taste. When installed at the main entry point, a UV system protects every tap, shower, and appliance in your Glass residence.
For UV to perform reliably, the water feeding the unit must be clear enough for the light to penetrate — heavy sediment, iron, or cloudiness can shield microbes from exposure. That’s why many whole-house installs in Glass pair UV with prefiltration, though the UV stage remains the key technology for targeting microorganisms like HPC bacteria. Correct sizing for your home’s flow rate plus regular lamp and sleeve maintenance keep the system effective; Mr. Pure Water can help size and install a whole-house UV system tailored to your plumbing so heterotrophic plate count is better controlled at the source.
