"At O3Fresh we specialize in sanitizing and disinfecting newly purchased/rented homes and apartments prior to the new tenant moving in. We use organic, chemical-free ozone (O3) to sanitize and eliminate over 99% of molds, bacteria, and viruses from all surfaces, air, and ductwork. While zone sanitizes it is very effective at eliminating cigarette, pet and other odors. Your health is a priority, so why move in with someone else's germs? Move in fresh with O3Fresh!"
