Probably because you don't have a humidifier, you're breathing in all this toxic soup of air. There is a way to clean it. What we do is actually do it naturally with things like UV lights, air cleaners. All that's done naturally. We're not adding chemical to the home. So between the indoor air quality and the lack of humidity, especially coming up in the wintertime, it's going to get really cold. Humidity makes you warmer. So actually, if you have a humidifier in your house, you can set the temperature itself lower and have the proper humidity and actually not run up your energy bill trying to keep it warmer, because humidity is like a blanket. It keeps you warm. So that is what I recommend. I have a humidifier my house. It's really nice to have that nice, fresh air in your home, especially when it's like 30 degrees outside.
