Including filter system and high-performance HPC Bacteria filter.
HPC bacteria are a wide-ranging group of microorganisms that can live in water and inside household plumbing. You may also hear the term heterotrophic plate count, which refers to the lab method used to estimate overall bacterial presence rather than a single pathogen. In Tiger Point homes these results can indicate plumbing or water conditions that let bacteria multiply; signs homeowners notice include musty smells, slimy buildup, or faster biofilm formation on showerheads and faucet screens.
Levels reported by heterotrophic plate count methods tend to climb when water stagnates in pipes, when sediment or organic material is present, or when plumbing allows biofilm to develop. Changes in taste or odor often accompany this general bacterial activity. While many heterotrophic bacteria aren’t known to cause disease, elevated HPC bacteria point to a water system that may need attention. For Tiger Point residences, addressing the water at the point it enters the house is an effective way to reduce conditions that permit regrowth downstream.
The most effective single-filter whole-house option for reducing HPC bacteria 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, treating water in real time without chemicals or altering taste. When installed where water enters a Tiger Point home, a UV system provides protection to every faucet, shower and appliance.
For UV to perform reliably, the water reaching the unit must be clear enough for the light to penetrate—heavy sediment, iron, or cloudiness can shield microbes. That’s why whole-house UV systems are often paired with prefiltration; the UV stage remains the core technology targeting microorganisms like HPC bacteria. Proper sizing to match your home’s flow rate and scheduled lamp and sleeve maintenance keep the system working well. Mr. Pure Water can help Tiger Point homeowners choose and size a whole-house UV system so heterotrophic plate count is better controlled at the source.
