However, when Ms. Li ran many pharmacies in Huayang, she found that she could not find the best 3M masks for online sales.

There are too many brands on the market to buy

Ms. Huang said, she asked the pharmacy salesman, and what brand of anti-haze mask that 3M has the same effect? ​​But what Ms. Huang did not think of was that the reply from the salesperson made her more puzzled. “The salesman said that there are N95, N90, and some other brands can be ah, not a 3M one.” Ms. Huang said that after asking too many pharmacies, I do not know what to buy masks. “Every pharmacy says different brands. I don’t know how to choose.” After consulting with Ms. Li, Ms. Huang decided to go to the supermarket to buy a green shield anti fog mask, but when Ms. Huang walked to the supermarket, the original pendulum There is no longer a mask on the shelf.

"There is no way, just buy one, and if you don't buy it, you'll have problems. There's always better than nothing." Ms. Huang said that although she bought an anti-fog mask at the end of the day, she still didn't feel right. After all, It's not the effect of the Internet posting. I don't know if I can prevent it from getting hazy. "First use it to see it. When the pharmacy is in stock, it's time to buy it." Ms. Huang said, "There are so many different kinds of things. There is an effect in my own family, but we don't understand people and don't even know how to choose."

Interviewee: Dr. Zhang, Department of Respiratory Medicine, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine

Warm mask

Advantages: Keep warm and keep cold: There is no protective effect on PM2.5

Dr. Zhang revealed that ordinary warm masks, mainly for keeping warm and keeping cold, are generally composed of several layers of cotton cloth, which have a blocking effect on large particles of dust, but do not have any protective effect on PM2.5 inhalable particles.

Medical masks

Advantages: Blocking particles above PM4 Disadvantages: Heavy pollution in the weather should not wear

Dr. Zhang said that this kind of mask can only block particles above PM4 in the prevention of inhalable particles, but it is also not useful for PM2.5 particles.

Special masks

Advantages: Blocks 99% of particulates Disadvantages: Poor comfort and breathability

The N95 was designed specifically to prevent the spread of droplets in the air during the SARS outbreak in 2003. Dr. Zhang said that the N95 can block more than 99% of particulate matter, but its comfort and breathability is not good, so it has a strong resistance to breathing.

Activated carbon mask

Advantages: Reduce odor Disadvantages: Activated carbon can also be inhaled

Active carbon anti-caries masks have certain dust-proof, filter-bacterial, and anti-virus effects, which have a deducting effect on certain odors, but have limited protection against PM2.5. Activated charcoal is also a kind of granule that may be inhaled by the wearer, so patients with chronic respiratory diseases or infirm should be used with caution.
