One thing learned by those who operate clean rooms is
that the proper kind of carpet can reduce dust. The carpet
holds dust while bare floors let it blow around. The carpet
must be kept well cleaned.
A sealer is important for preventing moisture from
penetrating the floor or wall. It may reduce dust from
disintgration of the surfaces but does not reduce dust from
other sources.
Creating a truely dust-free environment is not simple, it
can be done, as in high class clean rooms, but is expensive.
An electrostatic dust precipator can be helpful but when
such a machine isoperated in a darkroom one must make sure
it doesn't generate Ozone, which has a deleterious effect on
photographic materials.
