Air filtration apparatus

摘要

An air filtration apparatus operable to be coupled with an air return of a conventional HVAC system wherein the air filtration apparatus is configured to supply a continuous supply of unused air filtration media. The air filtration apparatus further includes a frame having four sides and an opening configured to accommodate any size air return. A first media receptacle and a second media receptacle are mounted on the frame. Disposed within said first media receptacle and said second media receptacle is an air filtration media, wherein the air filtration media is substantially disposed within the first media receptacle in its first position and is disposed within the second media receptacle in its second position. A drive assembly and fan are operably coupled to the air filtration media operable to transition the air filtration media intermediate its first position and second position as a result of airflow through the air return.
