摘要： A cylindrical or other suitably shaped filter container for insertion into a user's nares to filter inhaled air to remove airborne items. The filter container has two open ends forming a container surrounding filter material. Polypropylene may be used to form the container or tube. Other suitable material such as rubber or other softer material may also be used. The present disclosure further includes a respiration mask having a peripheral seal composed of treated and fluffed polypropylene fibers. An edge seal according to the present disclosure lowers the respiratory resistance of a mask and improves the filtration efficiency. Treated, fluffed, polypropylene may also be used to form a respiration mask, such a mask may also include an edge seal to improve filtration and comfort. Treated, meltblown, polypropylene may also be used to form a filter napkin or handkerchief that may be carried and used in short term or unexpected situations.
摘要翻译：一种圆柱形或其他适当形状的过滤容器，用于插入使用者的鼻孔以过滤吸入的空气以除去空气物品。过滤器容器具有形成围绕过滤材料的容器的两个开口端。聚丙烯可用于形成容器或管。也可以使用其它合适的材料，例如橡胶或其他较软的材料。本公开还包括具有由经处理和绒毛聚丙烯纤维组成的周边密封件的呼吸面罩。根据本公开的边缘密封件降低了掩模的呼吸阻力并提高了过滤效率。也可以使用经处理的绒毛聚丙烯来形成呼吸面罩，这样的面罩也可以包括边缘密封以改善过滤和舒适性。处理，熔喷，聚丙烯也可用于形成可以在短期或意外情况下携带和使用的过滤巾或手帕。
