Sundström SR900 half mask

Half mask made of TPE/PP, available in three sizes. Thanks to the two exhalation valves, breathing resistance is very low. The valve covers effectively protect the exhalation membrane from dust and paint particles. The mask body materials and colorants are FDA approved for food contact, so the risk of contact allergies is very low.
