We may not have the heat on full-time yet, but we soon will, and if you suffer from dry eyes, noses and throats each year because of your heat, there’s too little humidity in your home. This may not seem like a big deal, but too little humidity can actually cause as many problems as too much humidity, particularly when it comes to personal health. Adding a simple room humidifier, or several, doesn’t do the job necessary. Instead, you’ll want to consider the benefits a whole house humidifier can offer.
