How to keep quilts in rainy days?

Don't open doors and windows, especially for a long time;

Blow the quilt with a hair dryer for half an hour, pay attention to uniform heating, and don't blow only one place;

Vacuum packaging into the quilt to exhaust air. There are bags sold online. If there is no vacuum packaging bag, put it in a moisture-proof bag, zip it up, and check it once every half month to see if it is damp. If it is wet, repeat step 2.3.
