what is the ideal humidity outside
Just get a hygrometer to your home, and you can read the humidity levels precisely. A hygrometer is a little device that is user-friendly and inexpensive. Ideally, the humidity level between 40% and 50% is good for living. But if the temperature outside changes constantly, perhaps, you need a humidifier or a dehumidifier to maintain the right levels. The humidity level is decided by many factors, like the area and climate you are living, the season it is on, and forth.
