Indoor air with a humidity level of more than 50% is more typical in the Southeast, but it can occur anywhere that becomes hot and humid in the summer.
We often consider high humidity to be a problem that affects our health as well as our comfort.
Some of the effects of dry air are evident and irritating: scaly skin, static hair, and itchy scalp.
Heating systems that pump warm, dry air into the space also allow the air to become dry indoors throughout the winter.
