What is the preferred floor type for dust sampling?

Explanation:
The main idea is that dust-wipe sampling works best on smooth, non-porous floor surfaces. Hard, flat floors allow a clean, standardized wipe over a defined area, giving reliable and reproducible results. Carpeted floors trap dust within fibers, making it difficult to remove a representative amount with a wipe and introducing variability in the results. This is why carpeted floors are not preferred for dust sampling. Tile with grout or vinyl can be hard surfaces too, but the emphasis for standard dust sampling protocols is on hard, smooth floors, avoiding carpet where possible.
