Structure of medical masks

With a completely different design than conventional cloth masks, medical masks usually have from 2 to 5 different layers.

2 layer medical mask

2-layer medical masks are the thinnest, least-sized medical masks and have the least use.The construction of this medical mask is usually only 2 layers: an outer layer of waterproof nonwoven fabric and an inner layer of nonwoven fabric.Therefore, two-layer medical masks only work against large particles of dust such as soil and sand, but not against viruses, bacteria or fine dust.This type of mask is usually quite thin, some can see through the mask, so the price is also the cheapest among medical masks.

3-layer medical mask

3-layer medical masks are the most popular and most used medical masks currently.Structure of a 3-layer medical mask in the form of basic protection with:

1. The outer layer is a waterproof nonwoven fabric that helps prevent water from getting inside as well as blocks most of the large dirt, this layer is usually a colored layer to distinguish it from the innermost hygroscopic layer.
2. This is followed by an antibacterial filter cloth made of Polymer fibers, capable of minimizing harmful bacteria and dirt smaller than 10 micrometers.
3. The final layer is a non-woven fabric that has a strong hygroscopic ability, helping to prevent droplets from the nose, mouth of the user when speaking, coughing, sneezing .

3-layer masks are used in many hospitals, community health centers, concentrated medical isolation areas . because they are cheap and have enough basic preventive measures.

4-layer medical mask

In order to enhance the ability of dust masks for medical masks, manufacturers have launched a line of 4-layer medical masks, namely: Waterproof, non-woven outer layer, then a layer of fabric dust filter, antibacterial, followed by a layer of activated carbon and finished with a layer of desiccant to prevent mold.

In general, 4-layer medical masks are not much different from 3-layer medical masks, the biggest difference lies in the activated carbon filter cloth.Activated carbon has long been in the handling of impurities in the water, air . so it is also applied in mask manufacturing to increase the effect of fine dust filtration and prevent certain chemicals, toxic gases such as CO2, SO2, H2S . thereby minimizing the factors that adversely affect human health.

Currently activated carbon masks are usually divided into two main types: The type with activated carbon laminated sheet is placed between two layers of fabric and one is a woven fabric from activated yarn, sewn together.

5-layer medical mask

Compared with 2, 3 or 4-layer medical masks, 5-layer medical masks are a step forward that brings more preeminent effects.Structure of the most popular 5-layer medical masks currently includes layers: Airy layer, activated carbon layer, electrostatic precipitator layer (PM2.5 fine dust), small dust filter layer, non-woven waterproof cloth layer country.

The highlight of the 5-layer mask is that the electrostatic dust filter can remove fine PM2.5 dust, this is a very small size dust, when entering the body and penetrating into the cells by their blood. will destroy the autoimmune mechanism of the body causing many acute diseases and permanent damage to important organs such as lungs, heart, brain .
