This generally indicates that the plate is cracked or not making proper contact. Pull the plate and look very closely as even a tiny microscopic crack anywhere on the plate will produce these results.

When the unit is clean it will produce more ozone. If the unit is a bit oversized then it becomes worse. As an installer I have to be carefull to not oversize these units. O3 is harmless and actually will only stay in the air as O3 for about 1/2 hour. Because of this it will not build up in the air. O3 also in a powerful disinfectant and will help kill mold and bacteria in the air. As soon as the filter gets a little bit of dust on it the O3 production will become much less. Run your fan continuously for a day or so and it will go away.

You probably have a burned out high voltage transformer. That's what produces the ozone. Helpful hint...........the high voltage transformer is also the one used in bug zappers

Did you clean the plate contacts with alcohol? How old is the plate? Is the glue that holds the grid in place turning brown? If it is, it may need to be replaced. Call (336) 499-2505 and ask for free email supplemental cleaning instructions before you do anything else. The instructions may help you solve the problem.
