Negative effects of fine dust on health

Fine dust is a microscopic dust particle, less than 2.5 micrometers in size, that exists as liquid particles or particles floating in the air. The standard content of fine dust in 1 cubic meter of air is PM 2.5 .

Fine dust has very bad effects on human health:

• When entering deep into the respiratory tract, fine dust affects the structure of DNA and oxygen imbalance, which can lead to lung cancer.
• Causes respiratory diseases : Fine dust interacts with CO, SO2, NO2 causing oxygen deprivation to cells, leading to respiratory diseases, causing chronic lung congestion.
• Causes cardiovascular diseases : Fine dust can damage the alveoli, attack the circulatory system, and cause a heart attack.
• Deteriorating memory , affecting human psychology.

What is a fine dust mask?

Fine dust masks are masks made according to the following standards, to ensure the ability to filter fine dust:

• Non-woven fabric layer
• Small dust filter
• Fine dust filter layer
• Activated carbon layer (filter chemicals)
• Open class

With this structure, the anti-fine dust mask can filter fine dust with a size of 0.3 Micrometer .

According to the US Government Institute of Occupational Health and Safety – NIOSH, anti-fine dust masks are divided according to the following standards:

• N90 : Prevents 90% of fine dust with the smallest diameter of 0.3 Micrometer.
• N95 : Prevents 95% of fine dust with the smallest diameter of 0.3 Micrometer.
• N99 : Prevents 99% of fine dust with the smallest diameter of 0.3 Micrometer.
• N100 : Prevents 99.97% of fine dust with a minimum diameter of 0.3 Micrometers.
