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. These compounds can be present even when water appears clear and are different from simple taste-and-odor problems, so you might not notice them by smell or sight. Casselberry homeowners often learn about microcystins from utility advisories or local news; one frequently mentioned variant is microcystin-LR.
When microcystins are a concern in Casselberry, the aim is to limit exposure throughout the whole house — not only at the kitchen faucet. You use water for cooking, making ice, washing produce, brushing teeth and in showers, so treating only a single point isn’t enough. Because microcystins are dissolved organic toxins, sediment-only filters won’t reliably remove them. A whole-house system treats water at the main line so every tap and appliance receives the same protection.
For treating microcystins across your home, a single, well-built activated carbon filter is usually the best whole-house choice. Catalytic or high-capacity granular activated carbon is commonly recommended because it adsorbs microcystins, including microcystin-LR, as water flows through the media. This carbon solution is more robust than a basic taste-and-odor cartridge, providing greater adsorption and contact time when installed at the main water line before water reaches faucets, showers and appliances.
Effective microcystins control depends on matching the right carbon media to your home’s flow rate and proper filter sizing. In hard-water areas like Casselberry and Seminole County, rapid flow through an undersized unit can reduce contact time and cut adsorption performance. A correctly sized whole-house granular activated carbon system not only helps reduce microcystins but can improve overall water clarity and lower other organic odors; keeping the media replaced on schedule preserves that protection.
