No. True airborne protection (surgical N95s) are supposed to be fitted and airflow tested - at least in hospitals... I often wonder how effective they are if they are not? So, the masks I carry will not protect me from TB (airborne), but it will offer protection against bugs like the flu and meningitis (both are droplet). I guess it wouldn't hurt at all to carry N95s, since I'm sure they protect against droplet transmitted diseases, and may afford additional protection against airborne disease, regardless of whether or not they have been fitted.
