Including filter system and high-performance Microcystins filter.
Microcystins are toxins made by certain cyanobacteria, often called blue-green algae, that can make their way into drinking water during algae blooms. Because these compounds differ from common taste-and-odor problems, they can be present even when water appears clear. Delta homeowners typically learn about microcystins from utility alerts, local news, or seasonal advisories; one frequently mentioned form is microcystin-LR.
If microcystins are a concern in Delta, cutting exposure throughout the house matters—not just at the kitchen tap. Water used for cooking, making ice, rinsing produce and brushing teeth all count, and showers and appliances can also be pathways. Because microcystins are dissolved organics, plain sediment filters won’t reliably remove them. Installing treatment at the main line gives every faucet and fixture consistent protection.
For whole-home reduction of microcystins, a single high-quality activated carbon filter is generally the most effective choice. Catalytic or high-capacity granular activated carbon is commonly selected because it can adsorb microcystins, including microcystin-LR, as water flows through the media. This carbon approach is more robust than a simple taste-and-odor cartridge, emphasizing strong adsorption and sufficient contact time; placed at Delta homes’ main water line, it treats water before it reaches showers, faucets and appliances.
Effective control of microcystins depends on matching the carbon media to a proper flow rate and sizing the system for your Delta house. If water runs too fast through an undersized unit, adsorption won’t have enough contact time to work well. A correctly sized whole-house activated carbon system also helps reduce other organic tastes and odors and can improve overall water clarity; routine maintenance keeps the system performing when microcystins are present.
