Filtering Air flow in duct- With very minimum maintenance.


A Novel Reduced Maintenance Air Filtration System 

NJIT Case # 16-031 & 16-032


Inventors: Eon Soo Lee, Bharath Babu Nunna


Intellectual Property & Development status: Patent protection is pending.

NJIT is currently seeking commercial partners for the further development and commercialization of this opportunity.


Researchers at New Jersey Institute of Technology in the Department of Mechanical and Industrial Engineering have invented a novel, cheap and simple air filtration system, which filters the particle at micron level at continuum without any need of frequent maintenance.

The invention is a modular filtration system that uniquely offers reduced maintenance by preventing the accumulation of particles from blocking air ducts and easy replacement of the air filtration components if needed. Air filtration is performed with multiple modules with a flexibility to attach and detach these modules upon requirement however, each module of the filtration system function independently. This flexibility allows the filtration system for continuous usage. Additionally, the module system is easily customizable and able to adapt to the specific requirements of systems for various uses, weather conditions, and geographic locations. The invention has direct application in the multiple fields ranging from the simple domestic appliances like air-conditioning to complex industrial air filtration processes.
