Including filter system and high-performance Microcystins filter.
Microcystins are toxins made by certain cyanobacteria (sometimes called blue-green algae) that can show up in drinking sources during algae blooms. These contaminants aren’t the same as routine taste-and-odor problems and can be present even when water looks clear, so Old Town residents may learn about them through utility notices or local news. One commonly mentioned variant you may see in reports is microcystin-LR.
When microcystins are a concern in Old Town, the priority is limiting exposure everywhere in the house, not just at a single faucet. Cooking, ice, rinsing produce and brushing teeth are everyday uses that rely on safe water. Because microcystins are dissolved organic toxins, sediment-only filters won’t reliably remove them; a whole-house system provides consistent treatment so every tap and appliance gets the same protection.
For whole-home reduction of microcystins, a single, high-quality activated carbon filter is generally 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. This is more robust than a basic taste-and-odor cartridge, and when installed at the main line it treats water before it reaches showers, faucets, and appliances in your Old Town home.
Effective control depends on matching the carbon media to your home’s flow rate and properly sizing the unit for Old Town household demand. If water moves too fast through an undersized filter, there won’t be enough contact time for adsorption to work well. A correctly sized whole-house activated carbon system also helps reduce other organic odors and improves water clarity; routine maintenance keeps performance reliable when microcystins are present.
