When you spray PureAyre in the air or on surfaces powerful enzymes break apart the molecular bonds of odor-causing compounds to eliminate both odors and harmful contaminants. Smells are permanently removed when the molecular bonds are broken. Biotechnology has made it possible for us to bottle a potent combination of plant-derived enzymes without the use of chemicals or alcohol. Easily eliminate any odor including strong odors like cat urine, smoke, skunk and cooking smells.
