The answer to 'why is my floor dusty' is that there are several common causes, including poor air circulation, high foot traffic, and ineffective cleaning routines. Dust can accumulate on floors due to airborne particles, pet dander, and other debris being tracked in from outside.
To address a dusty floor, start by improving air circulation with fans or opening windows when possible. Regularly sweep, vacuum, or mop the floor to remove dust and dirt buildup. Depending on the flooring material, you may also need to use a damp mop or specialized cleaning products to effectively clean and maintain the surface.
