I have some commercial ozone machines for sale. They are Odor Stop 4500UV's. They will clean & remove odors from up to 4500sg/FT area. These ar a couple years old, with very little use. These are not the cheap Chinese ones. They are Commercial/Rental quality. They also work well for killing off wax moth larvae in beehive colonies. I will take $300.00/ea, or $250.00/ea if you buy 5 or more, and $200/ea if you buy 10 or more. I have many available. I can meet in Bountiful some days. No scammers.
