Mask Cleaning

Q. How do I clean my mask?

A. Follow the instructions below:

1.  Remove the canister. (If the canister becomes water-logged, it must be replaced
immediately. A canister becomes ineffective if immersed in, or heavily soaked with
water).
2.  Remove the communications lead, microphone assembly and voice projection unit (VPU), if
attached.
3.  Remove the protective hood if attached.
4.  Remove the drink coupler from its storage receptacle from around the VREU main body
5.  Remove the air deflector and inlet disk valve.
6. Immerse the mask in warm water containing a mild (baby-type non-allergic soap solution) or other
approved product.
7. Agitate the mask in this solution, wiping with a soft, lint-free cloth (face cloth)
particularly under the main seal and inner mask.
8. Remove the mask and shake off the excess solution.
9. Immerse the mask in clean warm water ensuring that all trace of solution is removed.
10. Lift out the mask and shake off excess water, then dry with clean, lint-free dry cloth, or
air dry.
11. To clean the hydration system, fill a canteen with a sterilizing solution and attach to the
drink coupler. Open drink valve and allow solution to run through and out of the
internal drink tube. Repeat with clean water.
12. Replace the inlet disk valve(s) and air deflectors, ensuring they are properly aligned.

13. Replace the mask components and store ready for use.

Cleaning the mask correctly is vital for maintaining its effectiveness in providing the best
possible protection. The mask should be cleaned regularly as part of the normal maintenance
and inspected routinely after each use.

If the mask is exposed to chemical warfare agents, special decontamination
and disposal procedures dictated by local established guidelines must be
followed. If the mask is contaminated with liquid chemical warfare agents,
dispose of the mask after decontamination.
