Including filter system and high-performance Microcystins filter.
Microcystins are toxins made by certain cyanobacteria (blue-green algae) and can get into drinking water during algal blooms. Because they’re dissolved compounds, microcystins can be present even when water looks and smells normal. Arundel homeowners may learn about microcystins from utility notices or local advisories; one commonly mentioned form is microcystin-LR.
When microcystins are a possibility, it’s important to reduce exposure throughout the whole house — not only at the kitchen sink. In humid subtropical Arundel, residents use water for cooking, ice, rinsing produce, and brushing teeth, so treating only a single tap leaves other routes unaddressed. Because microcystins are dissolved rather than particulate, sediment filters won’t reliably remove them; a whole-house system delivers consistent treatment to every faucet and appliance.
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 flows through the bed. This carbon treatment is more robust than a basic taste-and-odor cartridge and is installed at the main line so treated water reaches showers, faucets, and appliances across Arundel.
Good microcystins control depends on matching the carbon media to the home’s flow rate and proper sizing. If an undersized unit lets water pass too quickly, there won’t be enough contact time for adsorption. A correctly sized whole-house activated carbon system can also reduce other organic compounds that cause odor and help overall water clarity in Arundel; routine maintenance keeps its performance strong when microcystins are present.
