ONA PRO is new and exciting! These are products for professionals and are now available for you. The first product in this series is ONA PRO Gel. As we constantly strive to improve our Odor Neutralizing products we have developed a formulation that takes odor control to a new level. ONA PRO Gel is as close to odorless as we have ever come. Although it has a slight scent when sniffed in the container the final result when working on powerful noxious odors is simply a clean fresh smell - period. It leaves nothing behind to indicate that any odors were present. Nothing! Nada! Zilch! ONA PRO Gel is the best we've ever done and it is all you will ever need. No scrubbers no filters nothing - just ONA PRO.
