Hi Joanie,
Yes - it's the particles that you can't see that will do the most damage -
and they can stay suspended for a long time.
The beam (any central system) are noisy - a window fan will do the job as
long as its constructed properly to draw out all the dust. You will need to
have some replacment air for it to work properly - the stronger the fan the
more replacement air.
I use my beam for clean up - I have a window fan and hood for mixing glazes
and dusty jobs.
