Talking about the N95 mask/N95 respirator, it can be defined as a facepiece respirator that is helpful in particulate-filtering and it filters 95% of particles present in the air.

It is based on different filtration mechanism that safeguards you against harmful particulates.

N95 respirators are beneficial for different industries like construction, mining, painting etc. They are efficient in protecting against artificial nanoparticles. So, ideally, they are boon for industrial use.

According to NIOSH Respirator Selection Logic, the filters and respirators in N, R, & P series are highly recommended for the process of concentration of hazardous particulates larger than occupation exposure limit but can be fatal to health or life.

N95 series are effective for non-oil-based particles

N series respirators like N95 etc are useful for non oil-based particles like cutting fluids, lubricants, and glycerine.

When it comes to industrial setup there are chances of exposure to infectious diseases and in such cases, the users can easily wear a filtering facepiece respirator and reuse it until it gets soiled or damaged or till they find difficulty in breathing.

For healthcare industries

Well, whether it is a virus or a bacteria or any other airborne particle, people from various sectors need protection against these nanoparticles. Respirators help professionals in different sectors to protect from such airborne particles or aerosols. For example, for a health care provider who comes in contact with a patient, he needs protection against the infection from a contagious disease like tuberculosis or any other disease. In such cases, the N95 mask or respirator helps the health care provider create a barrier against the droplets that can catch infection through the patient.


Construction workers working on a construction site can be affected by the harmful airborne particles generated during sawing and concrete. The prolonged process of exposure to such particles can be harmful to lungs and overall health hence N95 respirator helps filter out the airborne particle to provide complete protection.

Laboratory technician

Similarly, the N95 respirator protects the lab technician while getting exposed to nanoparticles in the lab.

So the N, R and P series of these respiratory masks are efficient and are rated based on their resistance to oil and %age of airborne particles filtered

N series

95 – Not resistant to oil – 95% airborne particles filtered

99 - Not resistant to oil – 99% airborne particles filtered

100 - Not resistant to oil – 99.97% airborne particles filtered R Series

95 – Resistant to oil – 95% airborne particles filtered

99 - Resistant to oil – 99% airborne particles filtered

100 - Resistant to oil – 99.97% airborne particles filtered P Series 95 – Oil-Proof – 95% airborne particles filtered

99 – Oil-Proof – 99% airborne particles filtered

100 – Oil-proof – 99.97% airborne particles filtered
