In the context of the COVID-19 pandemic, wearing a face mask has become commonplace, both in hospitals and in the community. However, regardless of their speciality, the general public consumes surgical or filtering facepiece (FFP) masks, resulting in a global supply scarcity for the most vulnerable individuals, who are healthcare workers. This highlights the critical requirement to specify the indicators of the various mask categories such as bfe 95% mask to rationalise their use.
Materials used in making Masks:
While present models of masks and respirators provide adequate protection against airborne infections, there has been extensive research and development to increase their filtering qualities and performances, as well as comfort and user-friendliness. They include;
- Enhancing the mask material’s filtering capacity
- Additional functions and qualities can be incorporated into mask designs.
The former entails material development and engineering—how do we process bulk materials to reduce pore sizes so that they are small enough to capture and filter off minute particles and pathogens, and how do we treat or improve these materials so that they can inactivate microorganisms? The latter entails altering the existing design of mask models in order to confer antimicrobial features, for example, through the application of coatings, and to increase user comfort, friendliness, and conveniences, such as the addition of sensing and self-cleaning properties.
Different types of face masks:
Bfe masks are designed to trap droplets and particles that are expelled when you breathe, cough, or sneeze. They can also provide some protection from particles transferred by others, including the virus that causes COVID-19, if they fit close to the face.
Masks and respirators can give varying degrees of protection depending on the type of mask and how it is used. Loosely woven cloth items offer the least protection, layered finely woven materials provide more protection, well-fitting disposable surgical masks and bfe masks provide even more protection, and well-fitting NIOSH-approved respirators provide the most protection.
Choosing the Right Mask:
When selecting a mask, consider how well it fits. Gaps in the mask’s borders can allow air with respiratory droplets to slip in and out. Gaps can occur when the wrong size or type of mask is applied, as well as when a mask is worn with facial hair.
- It’s critical to make sure it fits snugly over your nose, lips, and chin.
- Cupping your hands around the exterior corners of the mask will reveal any gaps.
- Check that no air is coming out of the area around your eyes or from the sides of the mask.
- If the mask fits properly, you should be able to feel warm air coming through the front of the mask and see the mask material move in and out with each breath.
If you remove your bfe mask to eat or drink outside of your home, keep it clean by placing it in a safe place, such as your pocket, purse, or paper bag. After removing your mask, wash or sterilise your hands.
