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. Because these compounds differ from ordinary taste-and-odor problems, they can be present even when water appears clear. Lewis homeowners typically first learn about microcystins from utility notices, local news, or seasonal advisories. One frequently mentioned form is microcystin-LR.
If microcystins are a concern in Lewis, the priority is reducing exposure across the whole house, not just at the kitchen sink. Everyday uses—cooking, making ice, rinsing produce, and brushing teeth—are all potential contact points. Because microcystins are dissolved in water, sediment-only filters won’t reliably remove them. A whole-house system treats the water at the point it enters your Lewis home so all taps and appliances receive the same protection.
For whole-home reduction of microcystins, a single high-quality activated carbon filter is generally the most effective 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 carbon approach goes beyond a basic taste-and-odor cartridge, emphasizing stronger adsorption and adequate contact time. Installed at the main line, it treats water before it reaches showers, faucets, and appliances in Lewis residences.
Effective control of microcystins in a Lewis home depends on matching the right carbon media to the home's flow rate and filter size. If water passes too quickly through an undersized system, there may not be sufficient contact time for adsorption to remove contaminants. A properly sized whole-house activated carbon system can also lessen other organic compounds that cause odor and improve overall water clarity; regular maintenance keeps performance reliable when microcystins are present.
