AIR FILTRATION SYSTEM

摘要

An air filtration system is disclosed which incorporates a dual-layer electret filter having bypass openings in each layer for allowing a small portion of the air flowing through the filter to pass through the filter layer unfiltered. The system allows for the use of a smaller fan motor and a higher throughput of air while maintaining a laminar air flow and low back pressure resulting in an efficient and substantially quieter air filtration unit.
