Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a diverse group of naturally occurring microbes that can live in household water and inside plumbing. You may also see this referred to as heterotrophic plate count, which is actually a lab method used to estimate overall bacterial growth rather than naming one specific organism. High readings can indicate conditions that let bacteria multiply; in New Home houses that can show up as musty smells, slimy buildup around faucets and showerheads, or faster biofilm formation on fixtures.
Heterotrophic plate count numbers tend to increase when water stagnates in pipes, when sediment or organic material is present, or when biofilm is allowed to develop in plumbing. These factors can cause subtle changes in taste or odor alongside general bacterial activity. While many heterotrophic bacteria are not known to cause disease, elevated HPC bacteria can signal that a home's water system needs attention; in New Home, a whole-house strategy treats incoming water and reduces conditions that allow regrowth downstream.
The most effective single filter-style option for reducing HPC bacteria throughout a house is a whole-house ultraviolet (UV) disinfection system. UV inactivates microorganisms as water flows through a stainless steel chamber illuminated by a UV lamp, delivering treatment in real time without adding chemicals or altering the taste of water. When installed at the main supply into a New Home residence, UV protection works for every tap, shower, and water-using appliance.
For UV to perform reliably, the water entering the unit must be clear enough for light to reach microbes, since heavy sediment, iron, or cloudiness can shield organisms. That’s why whole-house UV systems are often paired with prefiltration, though the UV stage is the primary technology targeting microorganisms like HPC bacteria. Correct sizing for your home's flow rate and regular lamp and sleeve maintenance preserve effectiveness — Mr. Pure Water in New Home can help select and install the right whole-house UV setup for your plumbing and maintenance needs.
