Does a fabric desk mat collect more dust and allergens than a bare desk?

Yes, a fabric desk mat collects more dust and allergens than a bare desk because fabric traps particles like dust, pet dander, and pollen. A hard surface is easier to keep clean with a damp cloth. However, if you wash or vacuum the mat every couple of weeks, the allergen load stays low. For serious allergies, a leather or vegan leather mat is a better choice since it can be wiped clean.
