I bought a humidifier and in hour or so the air quality in my house changed. The oxygen level changed ,the house became very misty and
our gas stove was no longer burning effectivley and the color turned from blue to orange. We want to know why this humidifier changed the oxygen level in our house so traumatically.

I'm not to sure about the oxygen levels other than the more water from the mist the more oxygen that can be stored in that water and therefore less oxygen in the air. As for the humidifier, i'm not sure how accurate this is but i've heard before that if you have asthma, which wasn't specified, a humidifier does more bad than good.
