  • Conventional pollution masks are typically made of a non-breathable material that poses a number of issues including the build-up of moisture on the interior facing portion of the mask and a warm sensation for the wearer that makes long term wear unpleasant. While non-breathable, fine particulate matter may still traverse the barrier of the non-breathable material and enter the interior breathing area of the mask. For these and other reasons, tolerance of conventional pollution masks is very low and most wearers prefer not to wear them for extended periods of time. Moreover, conventional pollution masks lack aesthetic appeal and are not appealing to women. For example conventional pollution masks typically have a masculine appearance, interfere with the wearing of earrings, and do not match well with a female ensemble.

  • an earless filter mask may include a multi-layer construction that, at least partially, wraps around and conforms to the shape of the wearer’s face and tapers down in size to fasten at the nape of the wearer’s neck below the ears, without loops that are secured to the ears.
  • One or more filter layers may prevent the inhalation of polluted air through the fabric layers of the mask, while remaining constructed of breathable material, and a single exhalation valve may allow a wearer to breathe out while wearing the mask without the buildup of gases within the interior breathing area of the mask or a warm sensation for the wearer.
