N95 Masks Shelf Life in Years
N95 masks have manufacture designated shelf life. This means that the manufacturer states how long they think the masks will be effective, which is usually 2 to 5 years. The longer the mask is in storage the less effective it becomes. Factory Direct masks that are direct from a factory means they have not been shipped from warehouse to warehouse but are direct from the factory improving the shelf life.
