INDEPENDENT TEST OF SMARTVENT CRAWL SPACE VENTILATOR Smartvent, Inc. has received confirmation of how effective its crawl space ventilator really is. An independent study which recorded crawl space data every four hours over a one year period showed an average crawl space humidity of 46.4%. This confirms Smartvent's earlier study. Prior to the Smartvent installation in this crawl space, humidity was around 70% on the low end, 99% on the high end. Besides temperature and humidity, the Smartvent measures and compares how much water vapor is in outside and inside air.
