I can't help with the therapy, but I did fix my dust and dander without ozone.
I had the furnace man put a box for the larger 4" filters on my air return. I also have a motor with 2 speeds, so it can run on low speed 24/7. It only costs about as much as a 100 watt light bulb to run it.
My housekeeper is very happy not to have to dust much at all, and I have a cat, whole house carpeting, lots of stuff that makes dirt and mites.
