Olympia style air returns
These have the advantage of typically being on the shelf and ready to ship. However, it is not possible to make them in sizes other than the ones shown, unlike our other air returns.
These are designed to be used with a replaceable filter. This is convenient if you do not currently have a filter or if it is located in an inconvenient place to access such as a crawl space or attic. Of course, if you already have an easily accessible filter you can still use and Olympia style grille and simply refrain from putting a filter in it.
Choose from primed wood that is ready to paint, or natural wood suitable for staining and finishing.
