Snowbird washes, sterilises, grades and packages down for sale to wholesalers. Processing involves choosing excellent down material, advanced washing and degreasing technology and sterilizing equipment (see pictures below). Raw down is washed with detergents for approximately one hour and afterwards cleaned with water. After drying and cooling the downs are sorted with a special air separation method. With a controlled air flow, they pass several chambers. Due to the gravity, the lightest down travels the longest way and reaches the last chamber, while the feather only reaches the first chambers. With this procedure, the different qualities can be harvested from the different chambers and then be packed for the transport.
