功能

• The nose foam fits gently to the nose and also reduces the leakage of breath from the upper part of the mask.
• The closing strap has an adjuster, so it can be firmly fitted.
• The inside of the mask (contact area) is made of a soft fitting non-woven fabric.
• Because it is small, the lower visibility is also good.
• Since no metal parts are used, disposal is easy.
• General dust work.
