Why EZ Breathe Crawlspace Conditioner is Superior to
“Old School” Cross Ventilation:

Mechanical ventilation is the best answer for crawlspaces. Why? If you try to control moisture in a cool space with humid air from the outside through open vents, you are at the mercy of weather and wind and often end up with a damp, moist, moldy environment. Passive vents are no longer recommended as building codes across the country are changing to include mechanical ventilation in closed crawlspaces as the solution to keeping a crawlspace
healthy and dry.
“From a psychometric standpoint, venting a crawl space to remove moisture works only when the outside air is dryer than the crawl space air.” – RLC Engineering, LLC., The Fallacies of Venting Crawl Spaces
