Given that carbon dioxide is heavier than air, Is there any easy, inexpensive and simple way to use that fact to help people remove some of it from our homes and help improve air quality and cognitive function? I'd like to keep it at under 800ppm if at all possible!

I believe the normal recommendation is to just open the windows fully, if possible in both side of the house, for a short duration once or twice every day. In this way you will change all the air, but nut change the temperature more than necessary.
