Place the mask over the chin and pull upward, then adjust the head straps. After donning, cover the filter canister's air inlet with your palm and inhale forcefully. If the facepiece seals tightly against the face with no leakage, the mask is properly fitted and may be used in contaminated areas.

The dedicated water bottle cap should be pre-attached to the bottle. To drink, stabilize the mask with one hand, use the middle finger of the other hand to lift the drinking valve, then turn the handle 180° counterclockwise with your right hand. Grip the drinking tube inside the mask with your teeth, hold the bottle with your right hand, remove the bottle stopper with your left hand, insert the drinking valve into the dedicated cap, and lift the inverted bottle to eye level. Blow gently while drinking to ensure smooth water flow. Avoid lifting the bottle too high to prevent dislodging the valve. After drinking, restore the components in reverse order.

Keep the lens, exhalation valve, and inhalation valve clean. Rinse the facepiece with water if necessary.

After use in environments with infectious viruses: Wipe or wash the facepiece and filter canister with a 1% peracetic acid disinfectant solution. If necessary, the facepiece may be soaked in the solution, but the filter canister must not be immersed to avoid water damage. After disinfection, wipe the components with clean water and air dry before reuse.
