The outflow valves bleed the air back to atmosphere and regulate the cabin pressure in the process.
Although the air is "dry" it is flowing through the cabin at a greater rate than most normal buildings...
Hope that makes you feel better and cleaner on your next flight

thanks my man, that makes sense.
i guess the fact that it is so dry just makes me feel uneasy
