Different types of facemasks and their characteristics [10].

Type of masks	Mask Name	General Characteristics	Material Composition	Appearance
Surgical or Medical mask	Tie-on surgical facemask	Fluid resistant	3-ply, pleated rayon outer web with PP inner web
	Classical surgical mask	Protects the wearer from harmful fluids in the form of big drops, splashes, or sprays.	3-ply, pleated cellulose PP, PE
	Sofloop extra protection mask	It is not considered respiratory protection because it does not provide a reliable level of protection against inhaling tiny airborne particles.	3-ply, pleated blended cellulosic fibres with PP and PE, ethylene methyl acrylate strip, High filtration efficiency down to 0.6 μm
	Surgical grade cone-style mask		Moulded PP
Respirators (Breathing can be difficult while using these masks.)	N95 (N stands for non-Oil)	The minimum size of .3 μm of particulates and large droplets doesn't pass through the barrier	Nonwoven PP fabric, with 95% filtration efficiency, is produced by melt blowing and forms the inner filtration layer
	FFP1 (Identified by a yellow elastic band)	Mainly used as an environmental dust mask.	PP, aerosol filtration efficiency of at least 80% for 0.3 μm particles.
	FFP2 (Identified by a blue or white elastic band)	Serves as a protector against viruses of avian influenza, SARS with Coronavirus, pneumonia, and tuberculosis.	5-ply, PP, 94% filtration efficiency, net reinforced sheet.
	FFP3 (Identified by a red elastic band)	Protects against solid and liquid aerosols. Recommended for those who remain in contact with aerosols for prolonged periods.	5-ply, PP, 99% filtration efficiency.
			A mask can be graded as FFP3 only if it is waterproof and extremely impermeable
Non-certified mask	Cloth mask	Reusable. Recommended to wear one disposable mask underneath a cloth mask that has multiple layers of fabric.	Cotton used. Vinyl and non-breathable materials are not recommended for masks.
