Including filter system and high-performance Oxadiazon filter.
Oxadiazon is a herbicide used to control weeds that can sometimes enter source water from runoff. Because you can’t see or taste it, the only way to know if oxadiazon is in your tap water is through testing. If you live in Arran and want to limit potential exposure from every faucet, treating water at the point where it enters the house is a straightforward way to protect showers, sinks and appliances rather than relying on separate point-of-use devices.
Many synthetic organic chemicals dissolve into water without changing its appearance or flavor, and oxadiazon is one of those compounds typically linked to runoff rather than to the minerals that cause hard-water scale. That means common systems for hardness or sediment may not remove it. Homeowners in Arran who want broader protection often choose a whole-house strategy so the water you bathe in, cook with and launder in is treated, not only the water you drink.
For oxadiazon, the single most practical whole-house option is an activated carbon filter. Activated carbon adsorbs many organic contaminants as water passes through the media, and because oxadiazon is an organic herbicide, carbon is generally the preferred technology for this class of compounds. Installed at the main water line in an Arran home, a properly selected carbon system treats water for every fixture in the house in one step.
A carbon system performs best when it provides sufficient contact time and uses the right media—options like catalytic carbon or high-capacity granular activated carbon are chosen for broad VOC and herbicide reduction. Correct sizing is important because high household flow rates can shorten contact time and reduce adsorption if the tank is undersized. Adding a simple prefilter to protect the carbon from sediment also helps maintain consistent performance. Mr. Pure Water can assess your Arran home’s needs and recommend the right whole-house carbon setup so oxadiazon reduction is steady across every tap.
