N95 respirators for medical applications

N95 respirators are Class I medical devices that are made and/or imported by firms that possess a Medical Device Establishment License. N95 respirators provide a minimum filtration efficiency of 95%y.

When correctly worn, the edges of the face mask cover the area surrounding the mouth as well as the nose. N95 respirators are not medical masks. They are made to lower the possibilities of inhaling harmful aerosols and particles in the air.

N95 respirators safeguard against getting exposed to respiratory bacteria, and viruses. These masks are examined, tested, and certified by the U.S. National Institute for Occupational Safety and Health. They should pass minimum performance criteria that include breathing resistance, and filter efficiency.

Use of N95 masks after their shelf life

Most of the face masks have got a limited shelf life. They should be thrown once they reach their shelf life. The time for which you can store a respirator is dependent on two factors that include its shelf life or recommended storage conditions.

N95 masks whose shelf life is over are no longer certified by NIOSH. This is because the manufacturer-designated usage conditions are not met. So, they can’t get the NIOSH approval. However, due to a shortage of supply and an increase in consumer demands, one can use expired N95 respirators.  An expired N95 mask is only effective until:

  • its straps are unbroken and integral
  • they have no noticeable signs related to its damage
  • they provide the best fitting to the user
  • Medical providers should examine this mask and carry out a seal check.

Masks (medical masks, or surgical masks)

This type of mask is worn by a medical professional at the time of performing surgical procedures. They protect the patient as well as the staff in the operating room from the transfer of body fluids, particulate material, and micro-organisms.

Use of surgical masks after their shelf life

These masks can be used beyond their shelf life for the protection of health care providers. It is advised that they check that its straps are fully intact. Also, there have to be no signs of wear and tear. There is no precise timeframe set to use the mask after their expiry date.


Face masks that offer protection against COVID-19 are available in a broad range. Understanding about them and the right way to use them will save you from coronavirus to a considerable extent.
