Including filter system and high-performance Oxadiazon filter.
Oxadiazon is a herbicide used to control weeds that can sometimes make its way into source water from runoff or nearby applications. Because you can’t see or taste it, the only way to know whether oxadiazon is in your home’s water is a lab test — a step many McDavid homeowners choose to take for peace of mind. Treating water where it enters the house simplifies protection, so every tap in your home is covered rather than relying on individual pitchers or faucets.
Clear, good-tasting water can still contain trace man-made organic chemicals that only testing will reveal. Oxadiazon is typically introduced by runoff or incidental contamination rather than by the minerals that cause hard-water scale, so common treatments for hardness or sediment won’t reliably remove it. A whole-house system in McDavid reduces oxadiazon exposure across showers, sinks, laundry and appliances — not just the water you drink.
For reducing oxadiazon, the single most practical whole-home option is an activated carbon filter installed at the main water line. Activated carbon adsorbs many organic compounds as water passes through the media, and because oxadiazon is an organic herbicide, carbon filtration is generally the preferred technology for this class of contaminants. Installed at the point of entry, it treats water throughout your McDavid home in one step.
To work well, a whole-house carbon system needs adequate contact time and the appropriate media — for example, catalytic carbon or high-capacity granular activated carbon chosen for broad VOC and herbicide reduction. Proper sizing is important for McDavid homes because high household flow rates can shorten contact time if the tank is too small. Adding a simple sediment prefilter helps protect the carbon bed from clogging or channeling. Mr. Pure Water can assess your plumbing and match a whole-house carbon filter to your needs so oxadiazon reduction is steady at every tap.
