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!

Density separation of gases in the air is possible, however it is not easy or inexpensive. Modern methods require much higher pressures than could be achieved via inexpensive home equipment and would be dangerous. However, the easiest and most inexpensive way to limit CO2 in your house would be to limit the amount of CO2 generated by household objects. Alternatively, windows opened to the outside air will allow CO2 to diffuse to the lower level of CO2 in the atmosphere unless you live in an area in which the CO2 concentration is higher than 800pm. This however may not be the case if there is a larger amount of CO2 generation in the room than airflow will allow for diffusion out. If this is the case, increasing circulation with an HVAC system or fans may result in benefits.

are there any statistics or studies that evaluate the CO2 gradient depending on the heigth in a standard sized room or flat? Is there a significant difference for CO2 concentration between floor level and windows height?
user
Yes, there have been studies that have evaluated the gradient of CO2 concentration in indoor environments. The results of these studies have shown that there can be a significant difference in CO2 concentrations between the floor level and the height of the windows, with the highest concentrations typically found near the floor and lower concentrations near the ceiling. This is due to the fact that CO2 is heavier than air and therefore tends to sink to the lower levels of a room.
It is also important to note that other factors, such as the rate of CO2 generation, the rate of ventilation, and the overall size of the room, can also affect the concentration of CO2. For example, a smaller room with a high rate of CO2 generation and limited ventilation may have higher concentrations of CO2 than a larger room with the same CO2 generation rate but better ventilation.
