Barns are absolutely full of animal odors when there are animals present, and usually it's the smell of urine and fecal matter. Horses and cows, or whatever you may have stored in that barn, can create an odor like no other. Barns are also a magnet for mold and mildew because of the constant moisture that is absorbed into the wood. This can also cause the wood to rot over time unless the barn is treated, which can create a bigger problem than mold.

When awful odors of barn animals and mold are grouped together, the only solution is the Vertical Ozone Tornado 80-100k. This ozone generator is designed to clear the odors out of gymnasiums and large commercial buildings, which is why it's absolutely perfect to clear out barns.
