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 sources. Because it has no distinct taste or odor, most Fidelis homeowners wouldn’t notice it without a water test or a utility notice. Concerns often center on lingering residues or transformation products from past use. If you want a clear picture of what’s in your Fidelis water, starting with laboratory testing is the most reliable step.
As aldicarb degrades it can form related compounds such as aldicarb sulfoxide and aldicarb sulfone. Labs sometimes report these breakdown products separately, even though they trace back to the same original compound. If your Fidelis test results mention any of these names, consider them part of the same water-quality concern. Treating the whole house ensures those contaminants are addressed at every faucet, not just where you drink or cook.
To reduce aldicarb in household water, a whole-house granular activated carbon (GAC) filter is typically the best single-filter choice. GAC removes many organic chemicals by adsorption, capturing contaminants that sediment filters won’t. For homes in Fidelis, it’s important the system has a correctly sized carbon bed and sufficient contact time to handle peak flows; when sized and plumbed properly, a whole-home GAC tank treats water used for showers, laundry, and drinking taps consistently.
A properly designed whole-house GAC system can also reduce aldicarb sulfoxide and aldicarb sulfone, since they behave similarly in water. Performance varies with water chemistry, contaminant levels, and household usage, so pairing a targeted Fidelis water test with the carbon design helps determine the right media volume and replacement schedule. Regular maintenance is essential because carbon will eventually exhaust its capacity. Mr. Pure Water can evaluate your Fidelis home and size, install, and maintain a whole-house carbon system so your family gets treated water throughout the house.
