I looked around the crawl space some more and I had found a 6" vent leading to the side of the house. I had promptly installed a 5" electrical fan in the vent, allowing for air circulation by blowing the air out of the crawl space with adequate fresh air supply from the family room. What do you think is better - blowing the stale air out or blowing fresh air into the crawl space through the vent?
I had also read two other suggestions, one of which called for bleach and water wash, while the other called for O2 ionizer. Again, any ideas on the above?
