Including filter system and high-performance Oxadiazon filter.
Oxadiazon is a herbicide used to control weeds that can sometimes move from lawns or fields into source water. Because you can’t see or taste it, the only way to know if oxadiazon is in your supply is by testing. Many Campbell homeowners prefer to limit exposure as a precaution; treating water at the point where it enters your home makes it easy to protect every tap without treating fixtures individually.
Even in humid subtropical places like Campbell, water that looks and tastes fine can still contain man-made organic chemicals that only lab tests reveal. Oxadiazon is more likely to come from runoff or incidental contamination than from the minerals that cause hard-water scale, so typical hardness or sediment fixes won’t remove it. A whole-house system treats water used for bathing, cooking, laundry and more — not just drinking water — giving broader protection across your home.
For reducing oxadiazon, the best practical choice for most Campbell residences is a whole-house activated carbon filter. Activated carbon adsorbs many organic compounds as water passes through the media, and because oxadiazon is an organic herbicide, carbon filtration is the standard technology for this group of contaminants. When installed at the main water line, the system treats water for showers, sinks, and appliances in a single step.
To work reliably in a Campbell home, the carbon system needs adequate contact time and the appropriate media type — for example, catalytic carbon or high-capacity granular activated carbon 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 basic prefilter helps keep sediment from clogging the carbon bed. Mr. Pure Water can assess your home and recommend the right whole-house carbon setup so oxadiazon reduction is consistent at every tap.
