Abstract
A bag comprises an upper chamber and a lower chamber. The upper chamber comprises an inlet end defining an inlet opening. The lower chamber defines a lower chamber interior volume less than the upper chamber interior volume. A strainer is between the bottom end of the upper chamber and the top end of the lower chamber. The strainer places the upper chamber interior volume in fluid communication with the lower chamber interior volume. The bag wall may define an outlet port. A filter patch may be attached to the bag wall to cover the outlet port. The filter patch may be adapted to entrap airborne particles having a diameter of one micron or greater carried by air passing from the bag interior volume through the filter patch. The bag may be useful in enhancing the detectability of and in reducing the exposure to contaminants that may be present in mail deposited in the bags.
