Including filter system and high-performance Oxadiazon filter.
Oxadiazon is a herbicide used to control weeds that can sometimes reach drinking water through runoff. Because it’s invisible and tasteless, the only way to know if oxadiazon is in your plumbing is with testing. Many Fidelis homeowners choose to limit potential exposure as a precaution, and treating water at the point where it enters the house is a straightforward way to protect every tap.
Water that looks clear from the faucet can still carry synthetic organic chemicals that won’t show up without lab analysis. Oxadiazon typically arrives via runoff or incidental contamination, not from the minerals that cause scale, so common hardness or sediment fixes won’t remove it. Installing a whole-house system in your Fidelis residence helps reduce what you bathe in, cook with, and wash with—not just the water you drink.
The single most practical and effective option for reducing oxadiazon in most homes is a whole-house activated carbon filter. Activated carbon adsorbs a wide range of organic compounds, capturing them as water passes through the media. Because oxadiazon is an organic herbicide, whole-house carbon filtration is generally the preferred technology, and when placed at the main line it treats showers, sinks, laundry, and appliances throughout your Fidelis home.
For reliable oxadiazon reduction, the carbon system must provide sufficient contact time and use the appropriate media—options like catalytic carbon or high-capacity granular activated carbon are commonly chosen for VOC and herbicide removal. Correct sizing is important because high household flow rates can reduce adsorption if the tank is too small. A simple prefilter to remove sediment can also extend carbon life and performance.
