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 them called heterotrophic plate count, a laboratory method used to estimate overall bacterial presence rather than identify a single pathogen. High HPC results can indicate conditions that let bacteria multiply; around Majette homeowners sometimes notice things like musty smells, slimy buildup, or faster biofilm growth on faucet screens and showerheads when those conditions exist.
Heterotrophic plate count levels tend to increase when water stands in pipes, when sediment or organic material is present, or when plumbing encourages biofilm formation. Those situations can bring changes in taste or odor alongside general bacterial activity. While many heterotrophic bacteria are not known to cause disease, elevated HPC can be a signal your household water system needs attention. For Majette homes, addressing the water where it enters the house with a whole-house solution helps limit 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, treating water in real time without adding chemicals or altering taste. Installed at the main water entry to a Majette home, a properly sized UV unit protects every tap, shower, and appliance from heterotrophic plate count concerns.
For UV to work reliably the water entering the UV unit must be clear enough for light to penetrate—heavy sediment, iron, or cloudiness can shield microbes. That’s why whole-house UV systems are often paired with prefilters, while the UV stage remains the key technology targeting microorganisms like HPC bacteria. Correct sizing for your home’s flow rate and routine lamp and sleeve maintenance keep performance steady; Mr. Pure Water can help Majette homeowners choose and install the right whole-house UV setup to better control heterotrophic plate count at the source.
