Having lived now in Wa. state for 7 years i can attest to having been directly exposed to awful mold. Lived in Ocean Shores on the tip of the jetty (renting) and when i complained to the Landlord about the mold they had the siding removed and the whole wall was rotted with green and black mold spores. All in the basement.
I was going through a total knee replacement at the time and had aquired candida from all the heavy antibiotics required for that surgery. Surely i had breathed unknowingly plenty of mold during my 3 year stay there.
Moved up to Port Angeles and it is alot better in this house but thanks to MMS and my spray bottle of MMS i have a way to combat it both inside and out.
