Travel at home,away from germs
Filter with and breathe with ease.One time wear,safe and dust-proof.3 layers of protection and effective filtration;p2.5 dust.
1.The outer layer is non-woven;the adsorbed micro particles are moisture-proof and breathable.
2.The middle melt spraying layer has small breathing resistance.
3.The inner layer is non-woven;the skin friendly material is non irritating,and the filtration efficiency is ≥ 95%.Novel coronavirus,which is a lightweight respirator,has a smooth breathing,clean and no smell,protects the family and family members better,and has a mask for the trip.It is far from the virus to cover the mouth.
The dust blocking efficiency of the mask is based on its blocking efficiency of fine dust, especially respirable dust below 2.5 micrometers. Because this particle size of dust can be directly into the alveoli, human health caused the greatest impact. Gauze mask, its dust resistance principle is mechanical filtering, is when the dust impact gauze, through - layer upon layer of barrier, will be some large particles of dust barrier in the sand cloth. For some fine dust, especially dust smaller than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. Dust masks, made of activated carbon fiber felt pads or non-woven cloth, are used to filter air through respirable dust smaller than 2.5 microns
