Including filter system and high-performance Microcystins filter.
Microcystins are toxins created by certain cyanobacteria, often called blue-green algae, that can make their way into drinking water during algal blooms. These compounds are different from routine taste-and-odor problems and may be present even when water appears clear. Hanson homeowners typically first learn about microcystins from utility notices, local news, or seasonal advisories; one frequently mentioned form is microcystin-LR.
When microcystins are a potential issue, the focus should be on lowering exposure throughout the entire house, not only at the kitchen tap. Everyday uses such as cooking, making ice, rinsing produce, and brushing teeth all involve water that can carry dissolved contaminants. Because microcystins are dissolved rather than particulate, sediment-only filters won’t reliably remove them. A whole-house system installed for Hanson homes treats incoming water so every faucet 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 are commonly used because they can adsorb microcystins, including microcystin-LR, as water passes through the cartridge. This carbon treatment is more robust than a basic taste-and-odor cartridge, emphasizing strong adsorption and sufficient contact time. When installed at the main water line in a Hanson residence, it treats water before it reaches showers, faucets, and appliances.
Effective control of microcystins depends on matching the right carbon media to the home's flow rate and sizing the filter properly. If water flows too quickly through an undersized unit, adsorption contact time will be insufficient. A correctly sized whole-house activated carbon system for a Hanson home can also help reduce odors and other organic compounds, and routine maintenance keeps the system performing well so it continues to lower microcystins when they are present.
