Including filter system and high-performance Microcystins filter.
Microcystins are toxins made by certain cyanobacteria, often called blue-green algae, that can get into drinking water during algae blooms. They’re different from ordinary taste-and-odor problems and can be present even when water appears clear. In Franjo you may hear about microcystins through utility alerts, local news, or seasonal advisories; one variant you might see referenced is microcystin-LR.
When microcystins are a potential issue for Franjo households, it’s important to limit exposure everywhere in the house — not just at the kitchen faucet. Cooking, making ice, rinsing produce and brushing teeth all use the same water supply, so treating only a single tap leaves other uses unprotected. Because microcystins are dissolved organic toxins, sediment filters alone won’t reliably remove them; a whole-house system provides consistent treatment to every shower, faucet and appliance.
For whole-home reduction of microcystins in Franjo, 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 adsorbs microcystins, including microcystin-LR, as water passes through the bed. This kind of carbon system is more robust than a basic taste-and-odor cartridge and is designed to provide the contact time and adsorption needed when installed at the main water line.
Effective control in Franjo depends on matching the carbon media to the household’s flow rate and sizing the filter correctly. If water flows too fast through an undersized unit, adsorption won’t have enough contact time to work well. A properly sized whole-house activated carbon system also helps reduce other organic compounds that cause odor and can improve overall water clarity; keeping the media maintained on schedule preserves that performance over time.
