Impact of WTC smoke on museum HVAC systems

I was reading a report in the New York Times (Oct 11, 2001) about
the air quality in Manhattan as a result of the attack on the World
Trade Center.  I was wondering whether there was any negative impact
on air quality in the museums on Manhattan while the smoke pall was
hanging over mid-town New York.  Did filtration systems cope or not?
If not, what action was taken?
