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 supply is through testing. Many Willis homeowners choose to limit exposure as a precaution, and treating water at the point where it enters your house makes managing every tap — from showers to the kitchen sink — straightforward.
Even when Willis water looks clear and tastes fine, certain man-made organic compounds like oxadiazon can be dissolved and undetectable without lab analysis. Oxadiazon tends to be related to runoff or incidental contamination rather than the minerals that cause scale, so typical hardness or sediment fixes won’t reliably remove it. A whole-house solution reduces what your family bathes in, cooks with, and washes clothes in, not just what you drink.
A whole-house activated carbon filter is the most effective single option for reducing oxadiazon in most homes. Activated carbon adsorbs many organic compounds as water passes through the media, and because oxadiazon is an organic herbicide, carbon filtration is the preferred technology for this group of contaminants. Installed at the main water line, a properly set up system treats showers, faucets, laundry, and appliances in one step for peace of mind in Willis households.
For best performance you need sufficient contact time and the right carbon format — for example catalytic carbon or high-capacity granular activated carbon that targets a broad range of VOCs and herbicides. Correct sizing matters because high household flow rates can reduce adsorption if the tank is too small. Adding a simple prefilter helps protect the carbon bed from sediment and channeling. Mr. Pure Water can assess your Willis home’s needs and recommend the right whole-house carbon system so oxadiazon reduction is consistent at every tap.
