Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a broad group of naturally occurring microorganisms that can live in water and inside plumbing. You may also see this referred to as heterotrophic plate count, a laboratory method used to estimate overall bacterial growth rather than identify a single organism. Elevated HPC results often point to conditions that let microbes multiply, not one specific pathogen. In New Harmony houses, homeowners may notice signs such as musty smells, slimy buildup, or faster biofilm formation on faucets and showerheads when these types of bacteria are present.
Heterotrophic plate count numbers can increase when water sits stagnant in pipes, when sediment or organic material is available to feed growth, or when plumbing encourages biofilm to form. These changes can coincide with alterations in taste or odor, especially if organic matter is involved. Although many heterotrophic bacteria aren’t known to cause disease, higher HPC bacteria counts indicate your household water system may benefit from attention. For New Harmony homeowners, a whole-house strategy helps treat water as it enters the property and reduces conditions that allow regrowth further downstream.
To reduce HPC bacteria throughout a residence, the most effective single filter-style option is a whole-house ultraviolet (UV) disinfection system. UV inactivates microorganisms by exposing flowing water to a UV lamp inside a stainless steel chamber, treating water in real time without adding chemicals or altering taste. When installed at the point where water enters a New Harmony home, a UV system provides protection for every tap, shower, and appliance.
For UV to work dependably, the water feeding the unit must be clear enough for light to penetrate, since heavy sediment, iron, or cloudiness can shield microbes. That’s why whole-house UV systems are commonly paired with prefiltration; the UV stage remains the core 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 New Harmony homeowners choose and install a whole-house UV system matched to their plumbing so heterotrophic plate count is better controlled at the source.
