Aerodynamically designed and improved auxiliary blade attachment that wedge firmly onto the trailing edges of the main blades of conventional ceiling fans. The highly functional shape and super lightweight one-piece construction of these easy-to-use auxiliary blades and their strategic placement on the main fan blades serve to heighten the angle of incidence and thus create an intensified dual air current laterally and downwardly in relation to the fan\s central core. The result is a dynamic increase of cubic feet of propeller-cooled air per minute without electrically increasing the velocity of ceiling fan rotation.

Propeller breeze enhancing blade attachments for conventional ceiling fans wherein said auxiliary blades wedge firmly onto the trailing edges of primary fan blades to increase the angle of incidence and thus create a greatly increased dual air flow outward and downward in relation to the fan\s central core; said blade attachments comprised of top and bottom surfaces, leading and trailing side edges, and inner and outer ends; configuration of said top and bottom surfaces being convex and concave respectively, with said leading edge being of greater depth than said trailing edge, and said outer end being of greater width and lesser depth than said inner end, with said leading edge housing the means of securing said auxiliary blades to the primary fan blades via a flexible tapered groove along said auxiliary blades\leading edge extending from their inner end to their outer end.
