Surplus Condition

Never issued or used. Long-term military storage may result in minor cosmetic scuffs, finish variation, or differences in stamped inventory and lot codes. Photos show the actual product style and general condition.

“Unissued” describes the filter’s prior issue and use status only. It does not indicate that the filter is in date, currently certified, or suitable for protective use.
