With winter’s cold air on the way, it’s easy to get caught up in how well your furnace is warming up your home and completely forget about humidity. When you start heating for the winter, you may end up with respiratory problems, dry or cracking skin and a sore throat. To stay comfortable, you’ll need to humidify your indoor air. By keeping the moisture levels in your home at a moderate level, you’re ensuring that your home will remain comfortable through the worst winter weather.
