Every year about 3 million people are dying because of respiratory diseases which makes it the third leading cause of death globally.
An industrial respirator is designed to reduce the damage caused by breathing harmful substances in industrial environments. These particles are usually small enough to enter your body by inhalation and may lead to several health problems.
These pollutants (dust, mist, pollen, smoke, bacteria, virus, etc.) are usually smaller than 100 microns, much smaller than you can see with your own eyes. Thus, there is an urgent need for respirators while working in a polluted industrial environment to protect yourself from these toxic substances.
A respirator can be made of different materials, however, the most effective ones are reported the usage of nanofibers in at least one layer. FFP3 and N99 Nano Pak respirators contain a nanofibrous layer which increases the filtration efficiency up to 99% while maintaining low-pressure drop.
Standard and classification: Types of industrial respirators
The National Institute for Occupational Safety and Health (NIOSH) classifies the respirators based on their filtration efficiency according to the table below.
In this classification, respirators are divided into three series, N, R, and P.
|Classification of dust masks||Filter type||Efficiency|
|N series (non-greasy particles)||N95||95%|
|R Series (oil resistant particles)||R95||95%|
|Series P (oil insulating particles)||P95||95%|
Benefits of using nanofibers
- High filtration efficiency
- Low-pressure drop
- Low weight
- Longer filter life
Nanofibers usually need a substrate for mechanical support. Here, we use a melt-blown PP later as a substrate.
The European Union also classifies particle filtration according to its EN149 standard.
