Including filter system and high-performance Microcystins filter.
Microcystins are toxins produced by some cyanobacteria (blue-green algae) that can contaminate drinking water during algae blooms. Because these compounds differ from ordinary taste-and-odor problems, they can be present even when water appears clear. Pelican Marsh homeowners typically learn about microcystins through utility notices, local news, or seasonal advisories in the Naples/Collier County area. One frequently mentioned form of the toxin is microcystin-LR.
When microcystins are a potential issue, it’s important to reduce exposure across the whole house — not only at the kitchen sink. Everyday uses such as drinking, cooking, making ice, rinsing produce, and brushing teeth all matter. Because microcystins are dissolved organics, sediment filters alone won’t remove them. A whole-house system installed on the main line gives Pelican Marsh residents consistent protection at showers, faucets, and appliances throughout the home.
For whole-home reduction of microcystins, a single, high-quality activated carbon filter is the preferred choice. Catalytic or high-capacity granular activated carbon media is commonly used because it adsorbs microcystins — including microcystin-LR — as water flows through the bed. This is more robust than a basic taste-and-odor cartridge, providing stronger adsorption and sufficient contact time. Installed at the main water line in Pelican Marsh, the system treats water before it reaches fixtures and appliances.
Effective control depends on matching the carbon media to the home’s flow rate and sizing the filter correctly. If water passes too quickly through an undersized unit, contact time may be inadequate for adsorption to remove microcystins. A properly sized whole-house activated carbon system can also help reduce other organics that cause odor and improve overall water quality for hard water areas like Pelican Marsh; routine maintenance keeps performance reliable when microcystins are present.
