Block dirty air before it gets into your nose.
Reinvented with a new filter.
This simple, discreet, and ground-breaking nose mask is an evolution of our popular series of mask alternatives: the Nose Mask, Pit nose mask and Pit Stopper nose plug. The new mask is doubly effective.
It blocks 99% of PM 2.5 particles, airborne viruses, pollen, and more with a high-performance ultrafine particle (0.1 micrometer) filter; and also absorbs mucous excretions with a specially-processed sponge. This high-quality mask continues to filter 99% of 0.1 micrometer particles even after 10 rinses.
