No one but air freshener promoters can deny the power of ozone to literally destroy odors in the most challenging circumstances.  There are now thousands of services offering ozone removal with ozone generators, but not all ozone generators are created equal.  

Ozone oxidizes the odor at a molecular level.   Spray air fresheners either mask odor, trap odor, or attempt to kill bacteria at the source of odors.  These air freshener products are still only temporary fixes.  Popular product like Febreze has a masking fragrance and uses an innovative process to trap the odor.  So, the trash can can be turned into a bouquet of flowers smell.  The problem will return for a very obvious reason, the trash will continue to fester.  The product is little more than a temporary treatment that frankly does not live up to the TV commercial claims.  See Febreze Consumer Report.

By contrast, ozone always works on odors because it is simple science.  Ozone is enriched oxygen that lasts for about 20 minutes then goes back to oxygen.  While it is in ozone form, it will bond with odors at a molecular level and oxide them (burn them).  Ozone will also attack the bacteria that causes odors.  Ozone rips holes in the outer membrane of bacteria, and they die.

So, odor removal with ozone generators is frankly better than the boastful air freshener claims.  After all, if air fresheners really worked, you wouldn’t need to buy them over an over again.  All Ozone produces the best ozone generators for the price, and they may be the safest ozone generators on the market.
