Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide-ranging group of naturally occurring microbes that can live in water and inside plumbing. You may also see the term heterotrophic plate count, which describes the lab method used to estimate overall bacterial growth rather than a single organism. Elevated HPC results often point to conditions that let bacteria multiply, and homeowners in Century sometimes notice musty smells, slimy buildup, or faster biofilm formation on fixtures and showerheads when those conditions exist.
Levels of heterotrophic plate count can increase when water sits in pipes, when sediment or organic material is present, or when plumbing lets biofilm develop. These general bacterial changes can bring slight shifts in taste or odor, especially if organic matter is involved. Even though many heterotrophic bacteria aren’t linked to disease, higher HPC bacteria readings are a signal your household water system may need attention; treating the water as it enters a Century home helps limit regrowth further down the plumbing.
A whole-house ultraviolet (UV) disinfection system is generally the single filter–style option most effective at reducing HPC bacteria throughout a home. UV inactivates microorganisms as water flows through a stainless chamber and passes by a UV lamp, treating water in real time without adding chemicals or altering taste. When installed at the main supply to a Century residence, a properly sized UV unit offers protection to every tap, shower, and appliance.
For UV to work reliably, the water feeding the unit must be clear enough for light to penetrate, since heavy sediment, iron, or cloudiness can shield microbes from the lamp. That’s why many whole-house setups combine UV with prefiltration, while relying on the UV stage as the primary microbial control for HPC bacteria. Correct sizing for your home’s flow, plus routine lamp and sleeve maintenance, keep the system performing; Mr. Pure Water can help Century homeowners choose and install the right whole-house UV solution to better control heterotrophic plate count at the source.
