For instance, 90 percent relative humidity means that the air is holding 90 percent of the amount of moisture that air is capable of holding at that temperature.Can humidity go past 100%?
I have heard that relative humidity can exceed 100 percent. Is that possible? Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent.Is 80% humidity too high for house?

When we perspire, our bodies normally rely on air to get rid of the sweat that accumulates on the skin. This allows the body to cool down. When the humidity in the air is high, the warm moisture stays on our skin longer, making us feel even hotter. Meteorologists call this the “heat index”.Does running AC fan reduce humidity?

Water VaporIf there are no cold-condensing surfaces and the relative humidity (RH) is maintained below 60 percent indoors, there will not be enough water in those materials for mold to grow. However, if the RH stays above 70 percent indoors for extended periods of time, mold will almost certainly grow.
