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 dissolved compounds can be present even when water looks clear and aren’t the same as routine taste-and-odor problems. In the Christmas area homeowners typically hear about microcystins from utility alerts, local news, or seasonal advisories tied to nearby waterways like the Econlockhatchee River and Orlando Wetlands Park. One commonly mentioned variant is microcystin-LR.
When microcystins are a concern in Christmas homes—many of which use private wells in this rural part of Orange County—the aim is to lower exposure throughout the house, not just at the kitchen tap. Water used for drinking, cooking, making ice, rinsing produce, and brushing teeth all matter. Because microcystins are dissolved, simple sediment filters won’t reliably remove them, so a whole-house solution that treats every faucet, shower, and appliance is the better option for consistent protection.
For whole-home reduction of microcystins in Christmas, a single, high-quality activated carbon filter is generally the most effective choice. Catalytic or high-capacity granular activated carbon media are commonly used because they adsorb microcystins, including microcystin-LR, as water flows through the cartridge. This approach differs from a basic taste-and-odor cartridge by emphasizing strong adsorption and adequate contact time. Installed at the main water line, the system treats water before it reaches showers, faucets, and appliances across your property.
Good control of microcystins depends on matching the carbon media to your home's flow rate and sizing the filter correctly—especially important in hard-water areas like central Florida around Christmas where well water can carry iron or sulfur odors. If water moves too quickly through an undersized unit, there won’t be enough contact time for adsorption to work. A properly sized whole-house activated carbon system not only helps reduce microcystins but can also improve clarity and cut organic odors; routine maintenance keeps it working reliably when contaminants are present.
