Design of Polymeric Nanofiber Gauze Mask to Prevent Inhaling PM2.5 Particles from Haze Pollution

Table 4

Comparison of different masks.

Name	Material	The scope of use and effect	Problem
Medical masks	Non-woven fabric	For hospital outpatient, disposable, good sanitary conditions	Interception effect of fine particles is poor
	Blended material	For the operation room, disposable, good sanitary conditions	Water vapor is poor, respiratory resistance is high
ItoPM2.5 masks	Thickened non-woven fabric	Dedicated to filter PM2.5	Respiratory resistance
N95 masks	Thickened non-woven fabric	Protection of professional occupation, preventing a flow HINI and microbial particles	Respiratory resistance, poor comfort
R95	Activated carbon	Used for industrial dust and trace organic gas entrapment	Respiratory resistance, poor comfort
