Including filter system and high-performance HPC Bacteria filter.
HPC bacteria is a catch-all term for a variety of naturally occurring microbes that can live in water and inside plumbing. You may also see the term heterotrophic plate count, which is the lab method used to estimate overall bacterial activity rather than identifying one specific pathogen. In Bertha households these conditions can show up as musty smells, slippery buildup, or faster biofilm formation on faucets, showerheads and fixtures—issues made more noticeable in areas with hard, limestone-influenced water.
Heterotrophic plate count values tend to increase when water sits in pipes, when sediments or organic material are present, or when plumbing encourages biofilm growth. Those factors can cause changes in taste or odor alongside general bacterial activity. While many heterotrophic bacteria aren’t known to cause illness, elevated HPC bacteria are often a warning sign that a home’s water system deserves attention. For Bertha homeowners, a whole-house strategy addresses the water coming into the house and helps prevent regrowth further down the plumbing.
The most effective single-filter approach for reducing HPC bacteria throughout a house is a whole-house ultraviolet (UV) disinfection system. UV inactivates microorganisms as water flows through a stainless chamber and is exposed to a UV lamp, providing real-time treatment without chemicals or altering taste. Installed where water enters your Bertha home, a UV unit protects every tap, shower and appliance from heterotrophic plate count concerns.
For UV to work reliably the feed water must be clear enough for light to reach microbes—heavy sediment, iron or cloudiness can shield organisms. That’s why whole-house UV systems are often paired with prefiltration; 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 can help Bertha homeowners choose and install a whole-house UV setup that fits local plumbing and the region’s hard-water conditions.
