Including filter system and high-performance Protozoa filter.
Protozoa are microscopic living organisms that can enter water when surface runoff, wildlife, or treatment interruptions affect source water; homeowners may hear names like Giardia and Cryptosporidium. Because they are organisms rather than dissolved chemicals, they behave differently inside plumbing and aren’t solved by every filtration method. Effective treatment in Fidelis focuses on physically removing these cysts from your water rather than relying solely on chemical processes.
In Fidelis, questions about protozoa often arise after heavy storms, main breaks, boil-water notices, or when homes use private wells. These organisms can appear intermittently, so what seems safe one week may feel uncertain the next. Sometimes residents spot cloudiness or extra sediment, but protozoa are frequently invisible and don’t change taste or smell. A whole-house solution protects showers, appliances and every sink—not just the kitchen tap.
For whole-house protection against protozoa, the most reliable single solution is a correctly sized mechanical sediment filter with an absolute micron rating appropriate for protozoan cysts. In practice, that means an absolute 1-micron (or finer) filter that strains particles instead of using adsorption. This approach targets the size range of Giardia and Cryptosporidium, capturing them as water flows through, and when installed at the point of entry it helps keep protozoa out of your Fidelis home’s plumbing.
Because these fine mechanical filters remove contaminants by trapping tiny particles, proper flow-rate sizing and routine cartridge replacement are important to keep them working well. Homes with higher sediment—common after storms or on private wells—may want a coarse prefilter upstream to avoid premature clogging and loss of pressure. While disinfection has its place, a micron-rated barrier filter is a clear, dependable way to lower protozoa throughout the house, and Mr. Pure Water can size and install the right housing and cartridge for your Fidelis property.
