Optrel 4160.530 - Replacment Swiss Air Nose Foams
Supplied as a pack of 5 nose foams. When replacing this foam it is best to put the mask in a hot wash at 90 degrees which will soften the glue used to keep the nose foam in place. It can then be carefully peeled off and the new one applied.
All nose foams have a sliced part that can be removed if required for anyone with a larger or flatter shaped nose.
