Do you have fans at home?I'm sure you do. Over time they require frequent cleaning. Dust simply accumulates on these surfaces very quickly.

Not only for the blades, but for the standing fans, the metal casing as well. Washing the metal casing causes rust to form, and applying coatings that repel the dust, will make fans more worthwhile to have.
