moisture from our skin, hair, nose and throat mucous membranes, wood
floors, furniture plants, animals and anything else in the home. Medical
experts recommend a healthy relative humidity of 40-60% RH for the
home and the humidity introduced into the air conditioning systems
be sterilized vapor from steam humidifiers that boils the water.
