Showing how to sort mixed goose down and feathers for MYOG DIY project. I used this method to separate down from feathers, and recover good quality, large clusters down for my winter sleeping bag. Most of the final down clusters was a quarter size (2.5cm) and had approximate fill 800+. Cheaper than buying new expensive down. Also great to recycle down from old quilt, duvet or pillow.

The best setup used readily available items - see through plastic container, some vent tubing and a small bathroom vent (10wt), and cheap mesh zipper bags for collection.
1:00 First setup - tried copying tube columns used in industry. Failed as plastic bag tubes would collapse and sometimes leak down.
2:00 Second attempt - hard containers and large room for settlement. Also easy removal of sorted down, as well as waste.
5:44 Took about 2 days to process 4kgs. Maybe 30% of down lost in waste as it was well connected to feathers - price you pay to sort much faster than by hand. Also much cheaper than buying new down.
After sorting I recommend to treat it with UV light (or wash but be careful not to ruin) to sanitize before using in your project.
