I'm looking for an air purifier for my rat room as they are constantly sneezing and I've already put out hundreds on antibiotics. The Honeywell AirGenius 5 looked great! Did not list an ionizer, nor ozone, however on more internet searching it does put out a small amount of ozone. It claims to be well below the normal ozone production as the ionizer is not the main cleaning mechanism. https://afresherhome.com/honeywell-airgenius-5-vs-true-hepa/ Here is a website with additional details . I do not order online anymore as I've had cards hacoe multiple times. This is one of the only air purifiers in store. Better than nothing???? Or any suggestions?
