Does not work at all. The clean air signal is approximately 1.25 VDC. I put it in an ozone chamber to test it and it never registered a signal. The ozone was regulated from 0 to 5 ppm and the unit never gave more than 2 VDC. I ran it for 2 days and constantly monitored the ozone. No detection at all.
