Introducing the newest innovation in Ozone Generators from Sylvan. This little machine packs a big punch with 5G/Hr Ozone on max setting. The killer app on this machine is that you have variable ozone control. This allows you to set your ozone output from 0 to 5000mg/hr, so now you have an ozone generator that can be used in occupied spaces and be used as an air purifier even in small rooms with many air breathing carbon based life forms. With 0-120min timer and HOLD function you can set the OG-5000 to temporary shock treatments or continuous air purification mode. At the same time, if you have a huge room that has a decaying rat corpse, you can pump up the ozone and sterilize the smell 100% quickly and effectively with 5000mg/hr ozone output (be sure to remove the dead rat first). Ozone Generators are the only solution for reducing mold, mildew, odors, and bacteria. Need to remove mold caused by flooding? Look no further You have found the solution .

When choosing a brand of ozone machines, why not place your trust in the same brand as the Pro's? Reduce Black Mold, Mildew, Odors, Bacteria & Viruses Highly reactive ozone is created by our ozone generator. Ozone is a colorless gas made up of three atoms of oxygen (O3). It is one of the strongest disinfectants in the world with 3000 times the germ killing power of Chlorine OG-5000 has variable ozone output allows selection of adjustable ozone level from 0-5000mg/hr. When ozone comes in contact with mold and mildew, pollen, odors, or other airborne bacteria, one of those atoms combines with the pollutants rendering them inactive by oxidation, leaving behind pure clean oxygen. This high output ozone generator (up to 5000 mg/hr) can help: reduce/kill levels of airborne bacteria reduce/kill black mold and mildew reduce/kill fungi reduce/kill mold spores reduce/kill odors and viruses.
