Filtering respirators (dust, mist, and fume) are made to lessen exposure to particulate pollutants by inhalation. These respirators are used in the general industry to reduce exposure to particles like pollen, wood dust, and animal dander.

N-95 filtering facepiece respirators have recently been utilized in healthcare settings as part of their strategy for preventing Covid-19. Health Care Workers utilize them in this setting for protection against aerosolized infectious droplets emitted by unwell people.


Variety Of Filtering Respirators

Particulate FFRs can be purchased with or without an exhalation valve and are made of a multi-layer, non-woven polypropylene material. They can be found in a variety of shapes, such as:

  • Molded dome or cup that is semi-hard.
  • Flat-folded or folded
  • With an expanded breathing chamber, a pouch or duckbill

Particulate Filtering Respirators are only meant to be used once. They do not have a long life cycle because they cannot be washed. They should ideally be thrown out if they become distorted or damaged, moist or dirty, contaminated with bodily fluids, or incapable of effectively sealing to the face.

Safety Precautions Of Respirators

The Filtering facepiece respirators offer respirator protection against airborne particles, prevent contamination, and are intended for daily use under certain circumstances. But similar to any respirator, filtering respirators also have benefits and drawbacks. And when wearing one, you have to be cautious of the following factors.

  • When pollutant concentrations are immediately threatening to health or life, do not use this respirator.
  • If difficulty breathing, dizziness, or other symptoms develop, leave the polluted location right away.
  • Check to make sure the respirator is not being pushed or crushed by an outside force, since this could cause the respirator to deform and sustain damage. Pay closer attention, especially if the wearer is riding, running, or engaging in other activities.
  • Not advised for children under 3 years old.
  • Use with caution if you have a beard, other facial hair, or any other factors that make it difficult for the respirator sealing edge to form a tight seal on your face.
  • Failure to abide by all directions and precautions about the use of this respirator, as well as failure to wear it at all times when exposed, can impair its efficacy and lead to disease.


APF Of Filtering Respirators

The APF (Assigned Protection Factor) for all filtering facepiece respirators is 10. The respirator should theoretically minimize your exposure to a toxin by a factor of 10 in this case. In actual use, the degree of reduction is influenced by things including how snugly the mask fits your face, the size of the contaminant's particle, and the user setting. There are various types of filtering respirators, and the more protective the respirator, the greater the APF.


Air Purifying Respirators

The filtering respirators use filters or cartridges to remove impurities from the air before the user inhales it. These are the most often used respirators, and they come in powered, full-face, and half-mask versions.

Filtering Facepiece

A respirator's facepiece covers the user's mouth and nose (a full facepiece also protects the user's eyes). The facepiece and the face should form a gas- or dust-tight seal.

The facepiece is supported by headbands and has connectors for the air-purifying filters or cartridges as well as inhalation and exhalation valves.
