Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide-ranging group of naturally occurring microbes that can show up in household water and inside plumbing. You may also see them called heterotrophic plate count, a lab method used to estimate overall bacterial growth rather than identifying a single pathogen. High results often indicate conditions that favor bacterial multiplication — in Mission Bay’s humid subtropical environment this can mean faster biofilm and slime buildup in showerheads and faucets, or occasional musty odors that homeowners notice.
Heterotrophic plate count readings can climb when water sits in pipes, when sediment or organic material is present, or when plumbing allows biofilm to form. Those same conditions can lead to taste or odor changes alongside general bacterial activity. While many heterotrophic bacteria aren’t known to cause disease, elevated HPC bacteria levels are a useful signal that your water system needs attention. Treating the whole house — not just a single tap — helps address the water coming into Mission Bay homes and reduces opportunities for regrowth down the line.
For homeowners looking to lower HPC bacteria throughout the house, a whole-house ultraviolet (UV) disinfection system is generally the most effective single-filter solution. UV inactivates microorganisms as water passes through a stainless chamber exposed to a UV lamp, working in real time without chemicals or altering water taste. Installed at the main water inlet, a UV system provides protection to every faucet, shower and appliance in your Mission Bay residence.
For UV to perform reliably the water entering the unit must be clear enough for light to penetrate, since heavy sediment, iron, or cloudiness can shield microbes. That’s why many whole-house installations pair UV with prefiltration; the UV stage remains the core technology targeting microorganisms like HPC bacteria. Correct sizing for your home’s flow rate and regular lamp and sleeve maintenance keep the system working well — Mr. Pure Water can help Mission Bay homeowners choose and install the right whole-house UV setup to better control heterotrophic plate count at the source.
