I don't have that ozonics unit, but we have a plug in wall unit and we use an eco wash ozone unit on our washing machine. It adds ozone to the water before it goes to the washer and takes away the need for detergents. It works well on most stuff at removing odors, but if the clothes are real bad I usually add some borax to aid the cleaning process. So I can attest that the science of ozone works at removing odors, but as far as the portable battery units go I have no experience. I can add that the plug in wall unit I have works best in an enclosed space where the ozone can fully saturate the stuff. Not sure if this helps, but I'm an advocate of ozone for scent control, I just use it prior to the hunt, as I don't want another thing to truck into the tree.
