ZERO ODOR PRO is a patented technological breakthrough in commercial odor control/elimination. Odors/Smells that we consider unpleasant all share a consistent set of traits -like a signature, which ZERO ODOR PRO is attracted to. ZERO ODOR PRO seeks out and bonds with these odor molecules and permanently turns them into non-odor molecules; unlike traditional air fresheners, which simply mask bad odors with a fragrance temporarily, once ZERO ODOR PRO is sprayed in the air (or on a surface), any unpleasant odor that ZERO ODOR PRO comes into contact with is eliminated and permanently removed. ZERO ODOR PRO has been tested by an independent laboratory and gases that represent the constituent elements of all known odors and in all cases, ZERO ODOR PRO reduced the presence of the odor to an immeasurable level, permanently. Perfect for: Building/Facility Maintenance, Hotel/Hospitality environments, Transportation, Locker Rooms, Senior Living and Healthcare facilities, Veterinary Clinics, Urine/Bathroom odors, Fire, Smoke, Sewer Backup, Garbage, Water Damage and any unwanted odor, our PRO formula is Non-toxic, Non-irritating, Biodegradable, Cruelty free and safely used by customers around the world. Simply spray ZERO ODOR PRO where you have identified unwanted odor and the irreversible bonding process begins immediately, leaving the area odorless. Color: Clear.
