The combination of ODOGard® and our other technologies work to reduce VOCs and allergens such as pollen and pet dander, and odors caused by mold, bacteria and other pollutants. Plus, it is lab-tested to inactivate 99.98% of SARS-CoV-2 from the air, the virus that causes Covid-19. ODOGard® changes the molecular structure of the offending smell. When the odor molecule is captured, ODOGard® goes to work to scrub the stink, modifying the molecule until it is scentless. So unwelcome smells that have been lingering for days, weeks, months or even years can disappear for good in as little as 10 minutes.
