The optimum humidity recommended by medical specialists is in the range of 40 to 60% relative humidity. People perceive the air in indoor spaces with humidity in this range as pleasant and having optimum humidity. This humidity level is thus ideal for the health of people and animals as well as protecting furniture, wooden floors, musical instruments, antiques, plants and many more valuable items indoors from drying out.
