Including filter system and high-performance Microcystins filter.
Microcystins are toxins produced by certain cyanobacteria (often called blue-green algae) that can enter drinking water during algae blooms. These compounds behave differently than ordinary taste-and-odor problems and can be present even when water looks clear, so local notices or seasonal advisories are how many Zellwood homeowners first learn about them. One commonly referenced variant you may see mentioned is microcystin-LR.
When microcystins are a potential issue in Zellwood, it’s important to reduce exposure throughout the whole house—not just at the kitchen faucet. Water used for cooking, making ice, rinsing produce, bathing and brushing teeth can all matter, and because microcystins are dissolved contaminants, a sediment-only filter won’t reliably remove them. A whole-house system treats water at the main line so every shower, appliance and tap in your home gets the same protection.
For whole-home reduction of microcystins, a single high-quality activated carbon filter is typically the best choice. Catalytic or high-capacity granular activated carbon media is commonly used because it adsorbs microcystins, including microcystin-LR, as water passes through the media. This is a more robust carbon solution than a basic taste-and-odor cartridge, and when installed at the main water line in a Zellwood house it treats water before it reaches showers, faucets and appliances.
Effective control of microcystins depends on matching the right carbon media to your home’s flow rate and proper filter sizing—especially important in Central Florida where hard groundwater and mineral scale are common. If water moves too quickly through an undersized unit there won’t be enough contact time for adsorption. A correctly sized whole-house activated carbon system improves overall water quality, helps reduce organic odors, and with routine maintenance will keep reducing microcystins when they’re present.
