Why is my throat dry when I’m home? Dry air contributes to making your throat feel dry or aggravate respiratory ailments. During cold winter months, your home rapidly loses its humidity to the outdoors. Humidity levels could drop to as low as 10 percent. The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) recommends that homeowners maintain a humidity level between 30 and 60 percent. Dry air may also contribute to more than health problems. Static electricity is a direct result of very dry air and houseplants may suffer from "winter drought" caused by low humidity levels. A whole-home humidifier integrates moister with your indoor air and can help relieve ailments related to dry respiratory membranes and would be our recommended solution to this issue.
