Including filter system and high-performance Protozoa filter.
Protozoa are tiny organisms that can enter household water when surface runoff, wildlife, or treatment interruptions affect a source. Homeowners commonly hear the names Giardia and Cryptosporidium. Because these are living particles rather than dissolved chemicals, they behave differently in plumbing and aren’t removed by every filter type. In Portland residences, effective control is mainly about physically removing the organisms from the water.
In Portland, homeowners often worry about protozoa after boil-water advisories, storms, water-main repairs, or when using a private well. These microorganisms can appear sporadically, so water quality may seem to change from week to week. Sometimes you’ll notice cloudiness or extra sediment, but protozoa like Giardia or Cryptosporidium aren’t always visible and typically don’t alter taste or smell. A whole-house system gives Portland homes protection at showers, sinks, and appliances—not just the kitchen tap.
The single most effective whole-house option for reducing protozoa is a correctly sized mechanical sediment filter rated with an absolute micron rating appropriate for protozoan cysts. In practice that means an absolute 1-micron (or finer) cartridge that strains particles instead of relying on chemical adsorption. This kind of filter targets the size range of Giardia and Cryptosporidium and, when installed at the point of entry, helps keep these organisms out of all Portland home plumbing.
Because fine mechanical filters work by physically trapping very small particles, proper flow-rate sizing and routine cartridge replacements are crucial to keep them effective. Portland homes with heavier sediment may want a prefilter upstream to reduce clogging and pressure loss. While disinfection has a role in microbial control, a micron-rated barrier filter is a reliable, straightforward way to lower protozoa throughout the house—Mr. Pure Water can size and install the right whole-house housing and cartridge for your Portland property.
