Why Does the Box fan Get Dust?

When you are cleaning the fan blades, you may wonder why the fan blades would get dust which are sticks to the blades, especially the high flow box fan blades? Actually, it could an issue of static electricity. Most floating dust particles in your house have some sort of electric charge.

When you turn on the box fans, the fan blades move rapidly through the air, rubbing and brushing against air molecules, and pushing them out of the way. As a result, the charge would be accumulated on the edge of the rotating box fan’s blades. When the dust interacts with the edge of the fan blade, it would be attracted to the charged edge, and thus stick here.


Today, every family owns a box fan for confronting the hot wave of the summer, due to its practical function. To make your box fans work efficiently, cleaning the box fans is one of the most important things to implement.
