Traditional air ducts that are built in building walls or ceilings have been the main cause of indoor air pollution due to its own contamination by long time use.
Over-size commercial air ducts can be cleaned by professional duct cleaners or robots, but it is very hard to clean a residential, apartments, or hotels' air duct due to a small entrance.
This replaceable air duct has been developed to be attached inside a traditional air duct, and can be replaced when the duct is contaminated.
A replacement air duct is stationed in this chamber in the main duct. Open/close this chamber to take out/insert a replaceable duct.
