Have you ever been around a chain smoker? Rented a hotel room where a smoker stayed last? Walked into someone’s house, and knew just by the smell, that they had cats? Cooked fish and could still smell it days later? If so, then you know how difficult it is to clean the air in your home, your car, or your office….at times, it seems almost impossible! It’s times like these when you need an ozone machine.
