Types Of Reusable Face Mask
Many of the face masks have filter pockets to add a disposable filter between the layers.
Pleated masks – these masks are some of the most straightforward designs, consuming a rectangular piece of fabric, generally cotton, with pleats to fit your face.
Molded masks – another of the most common and mask designs, these face masks are more set to the face and may deliver a closer fit. They have a vertical seam, which has been criticized as a potential source of a leak. Some face masks, such as a 3m 1860 n95 mask, also have a filter pocket. Look for multiple-layered molded face masks, and ideally with built-in cloth layers relatively than a disposable filter.
Semi-reusable masks – are ready from similar materials to disposable face masks, but you can wear and wash them various times before replacing them.
Valved masks - be wary when purchasing a face mask with a valve as a lot of the time, the valve only filters airborne coming in and not the air you exhale, which refutes the point. Some of the higher-tech face masks that have been manufactured as the pandemic began may filter ways, but it is not the norm.
Clear face masks – widespread adoption of face coverings have bent communication problems for many people who rely on lip-reading to communicate; thus, face covers are available with a clear panel that people can lip-read. These come with their issues, such as the clear panel fogging up. It is also essential to ensure these face masks are still safe and breathable.
Types of face mask fabric
• Cotton tightly knit cotton is good at filtering particles, as proven and other face mask tests worldwide. But it is essential to use multiple layers, and ideally, combine different types of fabric.
• Polypropylene is a synthetic non-woven material and has good filtration and moisture-wicking properties. However, it is the same material used for disposable face masks.
• Polyester is suitable for filtration and moisture-wicking but, like cotton, wants to be used in multiple layers. Some commuter-style face masks use polyester on the outside and a more breathable, comfortable cotton layer on the inside to increase comfort for regular usage.
• Silk is generally tightly woven, so good at filtering particles. Silk is good at repelling water droplets, making it less susceptible to absorbing virus-laden droplets - but it has not been conclusively proven.
