Our scientists have uncovered a new patented technology that doesn`t use enzymes, fragrance or surfactants; instead, we`ve discovered a way to eliminate the odor at its source. A science all pet owners may not understand, but can definitely appreciate! Enzymes stop working, fragrance mixes a sweet smell with the foul one and odor-trappers only work for 3-7 days. Our proprietary Noble Ion® Odor Technology is the first new odor technology in over 20 years.  It completely eliminates the odor because it eliminates its source - so you know it will never return.
