Lennox HCSteam-16 Healthy Climate Residential Whole House Steam Humidifier - 15 Gallons Per Day There is a fine balance to getting humidity levels right in your home so the air isn't too moist or too dry. And that's where a whole-home humidifier from Healthy Climate Solutions comes in. Working with your central heating and cooling system, it adds moisture as needed to your home's air, making it healthier and more comfortable. Health - Many viruses and germs thrive in dry conditions, which can increase the likelihood of catching colds and other respiratory illnesses. Air dryness can also lead to nosebleeds and sinus headaches. Comfort - Too little moisture in the air can make your home feel cooler, even at normal temperatures. On top of feeling chilly, you may experience the unpleasantness of dry skin, chapped lips and static shocks. Home Protection - Overly dry air can pull moisture out of common household materials like plaster and wood.
