Review (2/5): 2 star rating would have been 4 with 2 filters, 5 with additional filters available
I have ordered these before. Have always come with 2-3D filters per mask. The 3D filters fit snuggly into shape of mask which is really nice. This time no filters. Mask performance is severely diminished without them. 2 filters per mask is barely enough. There does not seem to a any way to order additional filters.
