We are transitioning to a replacement for the 3M 1863+ mask. The new mask (3M 9330+) is a direct equivalent to the 3M 1863+ and therefore, if you have been face fitted for the 1863+ mask, you can use the 9330+ model.
Due to this transition your order from the last 4 week cycle may be delivered in two shipments on different days. You may also receive the replacement mask model. All orders from the last 4 week cycle, ending February 19th, will be delivered by Friday 5th March
