Including filter system and high-performance Oxadiazon filter.
Oxadiazon is a herbicide used to control weeds and can sometimes reach source water through runoff. Because it’s colorless and tasteless, the only way to know if oxadiazon is in your plumbing is a lab test, and many Century homeowners choose to limit any potential exposure as a precaution. Treating water at the main line makes it simple to protect every tap in the house rather than addressing fixtures one by one.
Even in homes where water looks clear and tastes fine, synthetic organic compounds like oxadiazon can be dissolved and invisible without testing. This herbicide is more likely to come from runoff or incidental contamination than from the minerals that cause scale, so solutions aimed at hardness or sediment won’t reliably remove it. A whole-house system in Century reduces what you bathe in, cook with, and wash with—not just what you drink.
For reducing oxadiazon, a whole-house activated carbon filter is the most practical and effective choice for most homes. Activated carbon adsorbs many organic chemicals as water passes through the media, and because oxadiazon is an organic herbicide, carbon filtration is typically the recommended technology. When installed at the main water line in Century homes, it treats water for showers, sinks, laundry, and appliances in one step.
To work well, a carbon system needs adequate contact time and the right media—examples include catalytic carbon or high-capacity granular activated carbon selected for broad VOC and herbicide reduction. Proper sizing is important for Century households because high flow rates can shorten contact time and reduce adsorption if the tank is undersized. Adding a simple prefilter helps keep sediment from clogging or channeling the carbon bed.
