Live Pee Free!® products use Liquid Positive Ion™ Odor Elimination Technology which is the first new odor elimination technology in over 20 years. We cancel the “negative” in odors with an equal amount of “positives” – sounds simple but we spent years developing our patented technology. Our products are safe for pets, kids, adults and the environment because we use no harmful chemicals, enzymes, fragrances, encapsulators or surfactants. And we are 5x more effective than the other guys so the odor won’t come back! Give us a whiff!
