Something that will work in your house is ozone. It oxidizes everything except for about 6 things, like fiberglass, silicone, another form of one of those two and two or three other things. Actually ozone will oxidize those things too, but it takes a long time.
Ozone is mother natures way of cleaning the air. You notice where ever there's high air polution, there high ozone levels? That's why. And the EPA's "science" behind ozone being bad is like saying firemen cause fires because every time there's a fire there's firemen.
My wife and I have been doing ozone for 7-8 years now. She had cancer in five locations (18 tumors total) and we cured it with a good diet, juicing
Anyway, I do know ozone. Every healthy cell in your body loves oxygen and will die within 7 mins. without it. So actually oxygen is the most important thing your body needs. And it will kill all bacteria, mold, fungus, virus, cancer and any unhealthy cells in your body if you get the ozone to it. This is what I plan on doing if that stuff comes my way. It will purify the water too. The only downfall is you need electricity to use it. Ozone killed the mold on the outside of my house, just to show how strong it is and how much penetrating power it has. You can read an article I wrote about ozone if you want at: http://alternativecancer.us/ozone.htm
Talk to ozoneman in the oxygen forum and get a generator from him. Or his site is at: http://www.ozonatedoilonline.com/home.html
You can get his phone number from the site and call him and talk to him if you like too. He's a nice guy and will help you out. A good system from him will cost $600-$800 if you use oxygen tanks. More if you buy an oxygen concentrator instead. (Probably $300 more?) My generator alone cost $2,000.
The only way you can purify the air when you're not in the house is buy some cheap battery powered generator, but that's not the best thing to breath, yet it's better than the stuff you're breathing now. Any ozone is better than no ozone.
Good Luck Rudi!
