Controlling Relative Humidity

The final piece of controlling the relative humidity in a crawl space and preventing future microbial growth is installing a dehumidifier. The dehumidifier will remove excess moisture from the air keeping the relative humidity below 60% and it will circulate the dry air throughout the crawl space. The dehumidifier will only turn on when the relative humidity rises over 55%, so it does not run all the time. A Hygrometer is also installed, a sensor is placed in the crawl space to send temperature and humidity readings to a unit in the home which reads temperature and humidity in the home and displays the results of both the crawl space and living space. This allows the homeowner to monitor the conditions of their crawl space.
