Properly integrated into an existing heating and air conditioning system, a whole house humidifier is the best way to effectively moisturize dry indoor air. It's like a nice lotion for every room in your house. But it's not a lotion, because it's a humidifier. It's really even better than lotion, because you won't run out on a Sunday night at 10:30 when it's freezing outside and you're ready for bed and you meant to get some Friday after work, but forgot because you have kids, a dog, and a goldfish no one cares about. And that's why you should get a whole house humidifier.
