I smoke cigars in the house daily and run 2 Csonka Units 24/7 - until they see the 2 very large Avallo Humidors in the house, most folks are not aware that cigars have been smoked indoors.....Even after a Winter Herf indoors attended by 7 other cigar lovers - the next day when we had friends over for Brunch - not 1 person noticed or commented on any stale Cigar tell tale aroma in the house.... I even asked them if they noticed any particular smells in the house - no one did. So as far as cloaking the cigar after smells - I've found the Csonka units to do an outstanding job...
Having said that - the # of articles coming out lately on the downside of having an ozone generator in your home are indeed quite numerous....but then the # of articles that condemn smoking are quite numerous as well......
