what should inside humidity be

The ideal humidity level for a home is between 30% and 60% relative humidity, depending on the time of year, what kind of clothes you’re wearing, and where your family is naturally comfortable. Research shows that the ideal relative humidity for a home is between 40% and 60%, but to discourage the growth and spread of mold, levels should be kept below 50% . In the summer, the ideal humidity level can be higher, between 50% and 60% . However, in the winter, indoor humidity levels shouldn’t exceed 30% if the outdoor temperature is between 0˚F and 10˚F, 25% if the outdoor temperature is between -10˚F and 0˚F, 20% if the outdoor temperature is between -20˚F and -10˚F, and 15% if the outdoor temperature is at -20˚F or lower. It is important to note that the ideal humidity level for a home can vary depending on the individuals comfort level, and it is recommended to use a device that can measure humidity to ensure that the levels are within the ideal range.
