Suffer from dry eyes, sore throat, chapped lips, and itchy skin? Live in a dry climate or one where you need to run air conditioning or heating a lot to stay comfortable? Then the air in your home, office, or shop may be too dry. Depending on where you live, controlling indoor humidity is not always easy and a humidifier may help. Humidifiers come in ultrasonic and mist models with ion exchange filters, some with heaters and some without, but all models are safe, cost-effective to operate, and have great health benefits if your home is too dry.
