Including filter system and high-performance Microcystins filter.
Microcystins are toxins produced by certain cyanobacteria—often called blue-green algae—that can make their way into drinking water during algal blooms. These compounds aren’t the same as ordinary taste-and-odor problems and can be present even when water appears clear, so Fidelis homeowners may learn about them through utility advisories, local reports, or seasonal notices. One frequently mentioned variant is microcystin-LR.
When microcystins are a concern in Fidelis households, it’s important to reduce exposure at every water outlet, not just at the kitchen sink. Water used for drinking, ice, cooking, rinsing produce, and brushing teeth can all be routes of contact. Because microcystins are dissolved contaminants, basic sediment filters won’t reliably remove them; a whole-house system helps ensure consistent treatment for every faucet and appliance in your home.
For whole-home reduction of microcystins, a single high-quality activated carbon filter is generally the best choice. Catalytic or high-capacity granular activated carbon media is commonly used because it can adsorb microcystins, including microcystin-LR, as water flows through the media. This is more robust than a simple taste-and-odor cartridge, and when installed at the main water line it treats water before it reaches showers, faucets, and appliances in Fidelis homes.
Effective control of microcystins depends on matching the carbon media to the home’s flow rate and sizing the filter appropriately. If water passes too quickly through an undersized unit, contact time will be insufficient for strong adsorption. A properly sized whole-house activated carbon system for a Fidelis residence can also help reduce other organic compounds that cause odors and improve overall water quality; routine maintenance keeps the system performing when microcystins are present.
