Including filter system and high-performance Protozoa filter.
Protozoa are tiny living organisms that can enter water supplies when surface runoff, wildlife activity, or treatment interruptions affect sources. Homeowners commonly hear names like Giardia and Cryptosporidium. Because these are organisms rather than dissolved chemicals, they behave differently in plumbing and aren’t removed by every filter type. In Watson, the practical takeaway is that effective control depends on physically removing them from the water.
In Watson, concerns about protozoa often appear after events like boil-water notices, storm runoff, main breaks, or when a household depends on a private well. These organisms can come and go, so water quality may seem unpredictable from one week to the next. Sometimes you’ll notice cloudiness or sediment, but protozoa aren’t always visible and usually don’t change taste or smell. A whole-house system gives Watson homeowners protection at showers, sinks, and appliances—not just at the kitchen tap.
For whole-house protection against protozoa, the most effective single solution is a properly sized mechanical sediment filter with an absolute micron rating appropriate for protozoan cysts. In practice this means an absolute 1-micron (or finer) cartridge that strains particles instead of relying on chemical adsorption. That size range captures organisms such as Giardia and Cryptosporidium as water moves through, and when installed at the point of entry it helps keep protozoa out of all plumbing in your Watson home.
Because fine mechanical filters remove contaminants by trapping very small particles, correct flow-rate sizing and timely cartridge replacement are key to reliable performance. Watson homes that see heavier sediment—especially properties on private wells—often benefit from an upstream prefilter to avoid frequent clogging and pressure loss. While disinfection has a role in microbial control, a micron-rated barrier filter is a straightforward, dependable way to reduce protozoa throughout the house, and Mr. Pure Water can size and install the right whole-house housing and cartridge for your needs.
