Mixed review

My experience has been mixed. I bought 4 B50s and they are not all working properly. One is working great, another was working great until it started making this awful buzzing noise that became impossible to leave plugged in and working because of the noise. The other two have been working quietly but no noticeable ozone emitting from them anymore. All in all I am pretty disappointed with the performance of these units.I like to leave them plugged in and working at all times especially now with the Covid-19 pandemic. I was hoping to have some comfort knowing the ozone would help help any virus brought into the house but I am not confident at all in this happening with the way these are operating.
