Medical Masks and its Different Types

Since the beginning of the pandemic, Kaelis has been using all of its supply-chain management capabilities in order to fight back coronavirus. We have been providing to companies and organizations around the world the best PPE products to protect their customers and workforce.

Even today, masks are still the most effective way to keep the virus away. We posted at the end of May another press release about different certifications and what each one of them meant. This time, we want to talk about medical masks and the differences between them.

A medical mask is a disposable device that is used as a barrier between the mouth and nose and the contaminant in the environment. If worn properly, they are able to block droplets that may contain viruses or bacteria, preventing them to enter your mouth and nose.



They are made of 3 or 4 layers made of Spunbond/Meltbond/Spunbond, a non-woven fabric that with low grammage achieves great longitudinal and transverse resistance that is the reason why it is so famous among the medical and hygiene sectors.

These masks play a major role in significantly reducing the exposure of your own secretions to others, that is why they are mandatory to use and even more in travel services.


There are three types of medical masks with their own specifications which are the following:
 
  • Medical Mask Type I: This kind of medical mask are the most common and has the ability to filter 95% of bacteria traveling in droplets, preventing them to get in contact with your mouth and nose;
 
  • Medical Mask Type II: This kind of medical mask can filter 98% of bacteria traveling in droplets; and
 
  • Medical Mask Type IIR: This kind of mask has the ability to filter 98% of bacteria traveling in droplets and is also resistant to (blood) splatter.
Table 1: Medical Masks Specifications per Type
Source: EN 14683:2019+AC:2019 Standard
BFE: Bacterial Filtration Efficiency measures the efficiency of bacteria filtering.
Breathability (ΔP) measures comfort while breathing.

Medical masks are not recommended to be used more than once and for no more than four hours. If the mask feels soiled or damaged, it should be removed. Once it has been taken off properly, you should discard it safely in a bag and you should put on a new one.
