Among the numerous models of dust masks currently on the market, it is not difficult for consumers to find out which face masks are quality. That’s thanks to the dust filter standard.
So, what is the content of that standard? Let ECO3D introduce to customers through the article below!
The international dust filter standard of protective face masks
Protective face masks are tools that help us prevent dust, harmful emissions or airborne germs. However, they also need to be selected and used properly for effective health protection. And the face masks to ensure human health need to meet the following international standards.
– Conventional fabrics can only filter dust larger than 10 micrometres, and smaller dirt, they do not do anything.
Thus, these face masks are only effective against the sun, not capable of filtering fine dust particles suspended in the air entering the human body through the respiratory tract.
– You need to carefully check the label to choose a product that can filter almost 100% of respiratory dust particles with the size of less than 5 micrometers.
– With international standard mask products, it will usually be denoted by the two above standards:
+ US dust filter standard (NIOSH): N95, N99, N100 with minimum filter efficiency equivalent to 95%, 99% and 99.97%.
+ European standard P1, P2, P3 with minimum filter efficiency equivalent to 80%, 94%, 99.95%
The criteria of a safe mask
Material
The material layers will determine the mask’s ability to filter small particles to how big. Medical or fabric masks are not able to filter out dust particles such as PM10 or PM2.5.
Select respirators that are certified for small dust filtration, such as N95, N99.
Face-hugging
Most masks sold in convenience stores do not qualify for face-hugging. “The worrying thing is, people wear them, go everywhere with the belief that they are being protected.”
Airy and aesthetics
In addition, two other factors that determine whether users are willing to wear the mask or not are the airiness of the mask and its aesthetics.
If a mask is secret, the air is difficult to pass through, the user’s breathing will face many difficulties, especially for those who exercise outdoors, the respiratory system is strongly active.
A protective face mask also needs to be highly aesthetically pleasing, meaning that the structure is not too out of the ordinary, with beautiful colors and textures. This makes users feel comfortable, confident and willing to wear the mask everywhere.
Choose the right mask
Protective face masks help us to avoid the entry of harmful bacteria or dust into the respiratory tract. Therefore, this tool needs to be made from quality materials. We should choose masks made from fabrics that are absorbent and easy to clean. The strap should be sturdy, with good elasticity to avoid straining.
The functions of the mask: Ordinary fabric masks that function to prevent dust and sun do not help prevent harmful emissions and pathogens.
It is recommended to use products containing activated carbon, which have the function of filtering dust, toxic substances in the air.
Dust affects human health, using masks of international standards to ensure health safety. “Where are the qualified protective face masks sold?” is a question that many people wonder.
