We recommend installation of a wireless monitor so that we can be sure the conditions in the crawlspace are favorable, and not worse, than the ambient conditions. This is because the temperature of the air affects how much moisture it can hold. In short, we feel that humid air is hotter than it really is. Low humidity levels magnify and heighten the evaporation of the moisture on your skin and the thermal loss it causes (evaporative cooling). Most pathogens like bacteria and viruses enjoy moist, damp environments. Relative humidity measures the saturation level of air with water; hence a relative humidity of 100% implies that the air cannot take any more moisture. Community Involvement Gas furnaces heat the air in your home with high heat. As a result, we feel much hotter than the actual temperature when the relative humidity is high. This is because humidity makes the air more saturated with water vapor, which causes the water in your hair to evaporate more quickly. Web100% Humidity simply means this is the saturation point at this temperature Saturation of the qty of water in the air.
