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. Because these compounds are dissolved, they can be present even when water appears clear and aren’t the same as ordinary taste-and-odor problems. In Whites Landing you may hear about microcystins from utility notices, local news, or seasonal advisories; one commonly discussed form is microcystin-LR.
When microcystins are a concern for Whites Landing homes, it’s important to reduce exposure throughout the house — not only at the kitchen sink. Water used for cooking, making ice, rinsing produce and brushing teeth can all be routes of contact. Because microcystins are dissolved contaminants, sediment filters alone won’t reliably remove them; a whole-house system gives consistent treatment to every faucet, shower and appliance.
For whole-home reduction of microcystins, a single high-quality activated carbon filter is typically the best choice. In particular, catalytic or high-capacity granular activated carbon media is commonly used because it adsorbs microcystins, including microcystin-LR, as water flows through the cartridge. This carbon treatment is more robust than a basic taste-and-odor cartridge and is sized to provide the contact time needed when installed at the main line serving a Whites Landing residence.
Effective control of microcystins depends on matching the right carbon media with appropriate flow rate and system sizing for your home. If water passes too rapidly through an undersized unit there won’t be sufficient contact time for adsorption. A correctly sized whole-house activated carbon system for a Whites Landing home can also reduce organic tastes and odors, and regular maintenance keeps the system performing when microcystins are present.
