Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide mix of naturally occurring microbes that can live in water and inside household plumbing. You may also see them called heterotrophic plate count, a lab method used to estimate overall bacterial growth rather than identify a single pathogen. Elevated results often point to conditions that let bacteria multiply, and homeowners in Florence sometimes notice signs such as musty smells, slimy deposits, or faster biofilm buildup on faucet aerators and showerheads.
Heterotrophic plate count numbers can increase when water stands in pipes, when sediment or organic material is present, or when plumbing allows biofilm to form. Changes in taste or odor may accompany this general bacterial activity. While many heterotrophic bacteria aren’t known to cause disease, higher HPC bacteria readings can indicate your home’s water system needs attention. Taking a whole-house view in Florence treats the water as it enters your property and helps reduce the conditions that allow regrowth downstream.
For reducing HPC bacteria throughout a residence, a whole-house ultraviolet (UV) disinfection system is commonly the most effective single filter–style solution. 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. When installed at the point where water enters a Florence home, UV protection works for every tap, shower, and appliance.
To ensure UV performs well, the water feeding the unit must be clear enough for ultraviolet light to reach microbes, since heavy sediment, iron, or cloudiness can shield them. That’s why whole-house UV systems are often paired with prefiltration, while the UV stage remains the core technology targeting HPC bacteria. Proper sizing for your home’s flow rate and regular lamp and sleeve maintenance keep the system effective—Mr. Pure Water in Florence can help select and install the right whole-house UV setup for your plumbing.
