I'll spell it out: H-U-M-I-D-I-T-Y.
Humidity and floating/levitating dust do not mix.
You go out into the jungle of Panama just after
the rainy season you won't find fine-dust levitated
in the atmosphere by electrostatics.
But here in Calgary, with it's dry air, dry winds,
and with the imminence of spring and the disappearing snow,
dust in the air has become a real problem.

But as for the moon?
I think an inflatable 'green house', integrated
either into a surface modular moonbase setup [or to a lavatube dwelling] is needed ....

....Grow things in that greenhouse, like fruits, tubers [potatoes?],
legumes, vegetables, etc, not only do you get fresh food on the moon, but oxygen in exchange for your CO2, and "humidity" to keep down the flaoting lunar-dust elsewhere in the station.

The "psychological benefit" of the greenery in the greenhouse
shouldn't be overlooked either.

And, if the large domelike greenhouse has a good sized central pond, a framed internal structure to keep its shape [and to support a diving board], the recreational benefits of that pond/pool are obvious.
Imagine diving into that 5-meter-deep pond/pool from a 10-meter-high
diving board at 1/6th G?

cheers.
