Including filter system and high-performance Aldicarb filter.
Aldicarb is a pesticide that can enter drinking water when it moves from treated land into groundwater or surface supplies. Because it has no taste or odor, most homeowners in Key West won’t notice it without a lab test or a utility notice. Over time the chemical and its residues may change, so testing is the only reliable way to know what’s in your pipes — especially in coastal Monroe County where salt air, storm events, and local conditions can affect plumbing and stored water.
As aldicarb degrades it can form related substances such as aldicarb sulfoxide and aldicarb sulfone, and lab reports may list those names separately. If you see any of these on a water report, treat them as part of the same contamination concern. For Key West homeowners who want protection beyond a single faucet — from Old Town to New Town — a whole-house strategy treats water used in showers, laundry and all taps, not just the kitchen sink.
The most effective single-filter choice for reducing aldicarb in household water is a whole-house granular activated carbon (GAC) system. GAC adsorbs many organic contaminants that sediment or particulate filters won’t catch, and when the tank is sized with enough carbon and contact time it can handle peak flows for a typical Key West home. Proper bed depth and correct flow rates are essential so the system treats water consistently for bathing, cooking and cleaning throughout the house.
A correctly designed whole-home GAC filter can also reduce aldicarb sulfoxide and aldicarb sulfone because they behave like related organic compounds. Performance depends on your water’s chemistry, contaminant levels and household use, so pairing a targeted test with the carbon system helps determine the media volume and replacement schedule. Regular maintenance is important since carbon becomes exhausted and loses effectiveness; Mr. Pure Water can help Key West residents size, install and maintain a whole-house carbon system so your family gets treated water from the Southernmost Point to Truman Annex.
