Abstract: The present invention improves both the quality and the flow of air delivered by a stationary fan such as a ceiling fan and a portable fan. Ceiling fans provide limited indoor air flow, but do not function as air conditioning and quality improvement apparatus. The present invention provides fans with an ability to increase indoor and outdoor air quality where they operate. One or a combination of a cooling unit and a heating unit and a filtering device and a secondary multidirectional fan provide consumers with air quality improvement options for stationary and portable fans to fulfill their specific needs for a given area.
