Cisco, I bought one of these little machines, on your reccommendation :), and have found it to be very effective indeed. I use it for fruit and veg, I wash my eggs (sometimes they get a bit of chicken doodoo on them) in ozonated water, and I also use it as an air purifier. This has worked very well on areas of mould in the bathroom, lol, and for fungal infections on my partners skin, worked well for treating conjunctivitis, ear infection, and skin wounds, and the list goes on.
It was a very inexpensive way to get into using ozone, and I have been very happy with this little dude.
I also agree with getting as many houseplants indoors as possible, and I have had good effects from salt lamps as well.
