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 algae blooms. These compounds aren’t the same as ordinary taste-and-odor problems and can be present even when water looks clear. In Lois, homeowners typically learn about microcystins from utility alerts, local news, or seasonal advisories. One commonly discussed form is microcystin-LR.
When microcystins are a potential issue, the priority is reducing exposure everywhere in the house—not just at the kitchen faucet. Water used for drinking, cooking, making ice, rinsing produce, and brushing teeth can all matter. Because microcystins are dissolved contaminants, basic sediment filters won’t reliably remove them. A whole-house solution gives Lois families consistent treatment at every tap and appliance.
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 unit. This kind of carbon system is more robust than a simple taste-and-odor cartridge, with media selected for strong adsorption and sufficient contact time, and when installed at the main water line it protects showers, faucets, and appliances throughout Lois homes.
Effective control depends on matching the right carbon media to the home’s flow rate and properly sizing the filter. If water moves too fast through an undersized system, there won’t be enough contact time for adsorption to work well. A correctly sized whole-house activated carbon unit can also improve water clarity and reduce other organic odors, and routine maintenance in Lois ensures steady performance when microcystins are present.
