What are the precautions for wearing a face mask

1. Wear masks during high flu seasons, haze days, sand days, illnesses, and visits to the hospital. In the winter, the elderly with low immunity and the frail patients go out to wear masks as much as possible.

2. Most of the color masks are made of chemical fiber fabrics, which have poor air permeability and chemical odors, which can easily cause damage to the respiratory tract. Qualified masks are made of gauze and nonwoven fabrics.

3. It is unscientific to run out of time and not clean in time. After wearing the mask for 4-6 hours, many germs will accumulate, and the mask must be washed every day.

4. Don't wear a mask to run, because the outdoor demand for oxygen is greater than usual, and the face mask may cause poor breathing or even hypoxia of the organs, which will have very serious consequences.

I. Dust blocking efficiency

The dust blocking efficiency of a mask is based on its blocking efficiency against fine dust, especially respiratory dust below 2.5 microns. Because this particle size can directly enter the alveoli, it has a great impact on human health. Dust mask consists of filter material activated carbon fiber felt or non-woven fabric. Respirable dust smaller than 2.5 microns is passed through this filter material.
