New houses need fresh air
The answer will move to action. A person will breathe in and vent per breathe 1/2 liter in quiet breathing to 6 liters or 1.58 gallons per minute.
Each person takes between 4 and 10 million breaths per year. The max volume of air that we take in and breathe out is called vital capacity. It’s about 4800 ml or about 5,000,000 gallons of air.
Each day, a person takes between 11 thousand to 28 thousand breaths per day per person or in other words about 13,698.6 gallons.
Calculates to 1,831.23 cubic feet per person must come into the house per day.
With this understanding, by tightening up our houses we need to bring in fresh air or we are going to poison our selves with our own exhaust air (CO2).
Installing an air exchanger into a new home is not an extra item that the state is forcing on us to do, but instead it is for our protection.
Having the Air Exchanger running 1 minute per hour per person in the house plus running it to remove humidity in the bathrooms while showers or hot tubs are running help stabilize the humidity in the entire house.
