This room is dust-free.

Let's go to the bar and lay the dust.

I need to empty the dust boxes.

There are many dust traps in the old house.

I need to clean the dust trap under the bed.

I need to buy new dust ruffles for my bed.

I need to buy a new dust ruffle for my bed.

I always use a dust bag to protect my expensive handbags.

I need to buy some dust bags for my vacuum cleaner.

We all return to dust eventually.
