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.

Description:
FIELD OF THE INVENTION 
     The present invention lies in the field of environmental engineering and more particularly to improve the quality and the flow of air delivered by fans. 
     BACKGROUND OF THE INVENTION 
     Currently, portable and stationary fans such as a ceiling fan provide only connection for a light fixture and do not provide direct and multiple connections to air quality improvement devices. The present invention provides fans with an ability to connect one or a combination of different air quality improvement devices such as heaters, coolers, filters, UV lights to improve and condition air where they operate. Therefore consumers are provided with versatile portable and stationary fans that heats and cools and filters the air as desired. 
     SUMMARY OF THE INVENTION 
     The present invention lies in the field of environmental engineering and more particularly to improve the quality of air delivered by fans. Currently, fans such as a ceiling fan provide only built-in connection for a light fixture and do not provide direct and multiple built-in connections to air quality improvement devices. The present invention provides multifunctional portable and stationary fans that include a universal connector for one or a combination of air quality improvement devices. The universal connector include easy and safe versatile mechanical, magnetic, and electrical connections for air quality improvement devices such as filters, heaters, coolers, UV lights, electrostatic filters, and ionization devices such as ozone generators. Therefor, consumers are provided with a multifunctional fan that conditions and improves air where it operates.
