It’s easy to hear “humidity” and think of hot, muggy summer days. But the truth is, your home does need some moisture for optimal comfort. Bloch’s air quality experts recommend humidifiers and dehumidifiers to balance your comfort year-round and avoid problems like dry skin, colds, mold growth, and allergies. Aim for a humidity level between 30 and 45 percent in the winter and between 50 and 60 percent in the summer.
