Absolutely love the HEPA air filter almost as much as the commercial ozone generator (just be out of the house while using ozone for the purpose of killing mold spores). Thanks to the ozone generator I didn't have to throw away all my books and porous items.
I use two small ones True Air by Hamilton Beach under $50 each with cleanable and reusable filters.
Ran it for 3 months straight in my master bedroom. Ran the other in my son's bedroom. The son's bedroom filter was relatively clean when I examined it.
This is where it gets really interesting and I kid you not. I went to clean the filter for the first time in the one running non stop in the master bedroom, and guess what I found.
These long thin 'spider web' like stands were all embedded in the filter. I wish I had saved these for lab analysis. I have yet to duplicate this ever again.
The only other person who I have ever seen reporting a similar thing happening to their HEPA air filter was Cliff Carnicom. He studied the material in his lab here:
/carnicominstitute.org/wp/extraordinary-biological-observations/The deeper I dig, the stranger it gets and I haven't even begun to get to the good stuff yet. I wont be posting it here, but if you stay tuned to my YouTube channel I will announce what I have found there.
No the link in the profile doesn't work for some reason. No links to it work no mater how I do it. So I would appreciate if you go there, search it, and subscribe to it. If for some reason you cannot find it, please let me know here as they are really starting to hammer down on me there.
