Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide group of naturally occurring microbes that can live in water and inside plumbing, sometimes noted as heterotrophic plate count in lab reports. That term refers to a testing method that estimates overall bacterial presence rather than identifying a single pathogen, and elevated readings often point to conditions that let bacteria grow. In Montverde homes — where mineral-rich, hard groundwater is common — homeowners may spot clues like musty smells, slippery residue, or faster buildup of biofilm around faucets and showerheads.
Heterotrophic plate count levels tend to increase when water sits in pipes, when sediment or organic matter is present, or when plumbing lets biofilm establish and persist. Those same factors can cause changes in taste or odor, and while many heterotrophic bacteria aren’t known to cause disease, higher HPC bacteria readings are a signal that your water system could use attention. Treating the water where it enters your Montverde house with a whole-house solution helps reduce the conditions that allow regrowth further down the plumbing.
To address HPC bacteria throughout a residence, a whole-house ultraviolet (UV) disinfection system is the most effective single filter-style option. UV inactivates microorganisms as water flows through a stainless chamber past a UV lamp, delivering real-time treatment without chemicals or altering taste. Installed at the main water entry for Montverde homes—so every tap, shower and appliance is covered—UV targets heterotrophic plate count concerns across the whole property.
For dependable UV performance, the water feeding the unit must be clear enough for the light to penetrate; heavy sediment, iron, or cloudiness can block UV and shelter microbes. That’s why whole-house UV systems are often paired with prefiltration ahead of the lamp. Correct sizing for your home’s flow rate and regular lamp and sleeve maintenance keep the system working well. Mr. Pure Water can evaluate Montverde plumbing and hard, mineral-rich source water to recommend the right UV system and prefiltration setup for reliable control of heterotrophic plate count.
