Healthly air in rooms

[jjaammeess]

Coming into the winter you are told to draft proof your house. But how much. I bought this rather expensive meter to tell me the quality of the air and I was surprised how easy it is to fill your room with stale unhealthy air For example if two people are sitting in a room and the window is opened slightly in about half an hour the air becomes unacceptably stale(according to the meter) resulting in headaches etc. Has anybody any experience of dealing with this problem of providing healthly air with minimum heat loss.I would like to know how they solved it.
