It is intended to be used for hospitals, residences and businesses. The edge clip is adapted for: (a) reliable attachment, (b) structural compatibility with select classes of ceiling fans, (c) easy removal, (d) low-cost replacement and (d) user-friendliness. It is adaptable for being colored and designed for matching aesthetics of the select classes of ceiling fans and use conditions. The gluey adherent can include predetermined surface corrugation and unevenness for maximizing germ and particle retainment.

Both the first and second fin portions extend outwardly from the trailing edge of the body at an angle to this trailing edge. Generally a slot or gap would exist between these first and second fin portions and both such fin portions would have a tapered width which narrows in the direction of the tip end. Additionally, the width of the first fin portion would be greater than the width of the second fin portion. Furthermore, the two fin portions may or may not be co-planar in order to optimize air flow.

Width extender can be made of an extruded plastic material, preferably nylon, or it can be constructed of the same material as the fan blade itself. Ideally, the width extender would increase the width of the fan blade by 20% to 25%. Additionally, this width extender would have a uniform length so as to uniformly increase the entire width of the fan blade.
