Suggested Size: Best models: UV PRO 550, 550AT, 1100, & 1100AT, 2700, 4000, 6800, PRO 3600-5, 5000, 9000-2 alternate models for small areas: PRO 450, 700, 970, 3400-1, 3600-1. Depending on the size of area to be treated.

To reduce odors and reduce cross contamination of foods to other foods, install a Crystal Air ozone generator in an out of the way place, with an additional fan to circulate the ozone efficiently throughout the entire area to be treated. Next install an ozone generator monitor controller in the center of the treated area to ensure the levels of ozone do not exceed the limits set by the Workers Compensation Board Of BC which are .08 ppm. averaged over an eight hour work period. The controller will cycle on and off as needed to maintain and control the ozone at the proper levels.
