Goodman GMH81405DN Air Filter
The filter filters out all the dust and other fine particles from the air handler as well as the home. Professionals in the industry advise that the filter that filters out particles from your home gets replaced every 90 days or so for optimal air quality through the ducts. The actual dimensions of the filter is not really a choice that needs to be made due to the requirement of the manufacturer of your system.
