Abstract

1,231,800. Nasal filters. E. C. S. LITTLE. 26 July, 1968 [28 July, 1967], No. 34926/67. Heading A5T. [Also in Division G2] Protective means for restricting the ingress of air-borne particles, such as pollen into the head includes a nasal filter consisting of a pad of resilient cellular material permeable to air, for example polyurethane foam, and shaped to fit the nostril cavity. To reduce the impediment to breathing a series of tapered bores 14 are provided which extend from the front face 11 to a position adjacent the rear face 12. The protective means can also include a pair of eye shields (1), Figs. 1-4, not shown, (see Heading G2J).
