1. Function

  NOSK only filters hazardous minute substances without causing any breathing barriers.

2. Materials

  Clip: POE(Polyolefin Elastomer)
  Filters: S/M/S

High efficient non-toxic 3-layered material makes up the filters, and the transparent clip part is made of licensed non-toxic POE. Hygienic and mini case included.

    S/M/S is...
    The acronym of SMS stands for three layers of materials: Spunbond-Meltblown-Spunbond.
In SMS construction, cloth-like, abrasion resistant spunbond polypropylene forms the outer layers.
The inner layer is formed from a web of microfibers that filter out many water-based liquids.
The outer spunbond layers are made up of randomly deposited 15-20 micron diameter continuous
polypropylene fibers that serve to provide fabric strength, durability, abrasion resistance, and protection for the meltblown layer.
The inner meltblown layer provides a barrier and is typically comprised of 1-3 micron.

3. Design based human body.

  Ease of breathing and wearing comfortable. Virtually invisible when you wearing.
