3M Aura Sampler Pack (3 masks)

Try them all! 

White headbands tend to be the tightest, followed by red, then blue (loosest). Red auras have additional water-resistant coating typically for surgical applications (slightly less breathable, but more water resistant - think rain). Individually sealed in original manufacturer bags.

Expiration dates:

Blue (9205) - 06/26

White (9210) - 09/25

Red (1870) - 08/26
