Offered Ozonator Generators can be safely operated in their higher settings in an head-to-head room as long as the gate is shut, or another fence (plastic sheet) is active between the engaged space and the room being used. Generating ozone in the crypt while you occupy the upper floors is normally not problematic as ozone is weightier than air so it will persist down it the basement. The generators are suited for certain specific applications such as killing mold, mildew, bacteria and getting rid of odors. These are up-front, cooler running; high yield ozone generators that can "stun" treat the whole home in one shot. Our exclusive Ozone Generator need no patching or wiring and are anything but difficult to change out when they at long last crap out.
