These Helmet disposable face masks provide a practical layer of protection for adults in non-medical settings such as offices, supermarkets, or other public spaces. Each mask is constructed from three layers of non-woven polypropylene, starting with a durable outer shell designed to block splashes and a middle filter that captures particles and aerosols as small as 0.3 microns. To ensure you stay comfortable during extended wear, the inner layer is made from a soft, hypoallergenic material that is gentle on the skin. The masks come in a blue finish and feature elastic ear loops to ensure a secure fit for most face shapes. For added hygiene and convenience, the box contains 50 pieces, with each mask individually wrapped so you can easily carry a few with you throughout the day.
