You’ve probably heard the claims that humidity is responsible for discomfort in the summer, and not the heat itself. While certainly an over-simplification of the scenario, there is some truth to this. If your home is too humid, it is going to be tough to live in it comfortably.
Don’t let this give humidity a bad reputation in your opinion, though, because the fact of the matter is that a very dry home is no better than a very humid one. If you home is lacking in the humidity department, you are wise to consider the use of a whole-house humidifier.
