The Six Problems Caused by Dry Air, and How to Combat Them.

As the cold weather moves in, humidity levels naturally drop. That’s because cold air can’t hold as much moisture as warm air. Ideal indoor humidity during winter should hover around 45 percent. But dry winter air can cause your humidity to drop substantially, to levels of 15 percent or less. With this humidity imbalance come a number of potential problems that can affect your health, your home and especially your comfort.
