When talking about masks, first talk about air quality. When talking about air quality, the airquality quality index (aqi) and PM2.5 must be introduced.

1、PM2.5

The main components of smog are sulfur dioxide, nitrogen oxides and inhalable particulate matter. The inhalable particulate matter is what we often call PM(particulate matter). The PM2.5 we often say is pollutant particles with a diameter of less than or equal to 2.5 microns, also known as fine particles or lung particles, which can directly enter the lungs.

2. Air Quality Index

It can be seen that there are serious environmental problems in most categories across the country, and masks should indeed become a daily necessity for people.

3. New national standard

Therefore, combined with the current air quality, we can judge how to buy masks.

Daily use of civilian masks is not necessarily necessary:

1. Price-the importance of self-evident, almost become a fatal killer.

2. Brand-The higher the brand degree, the greater the attention and the more complete the understandable information.

3. Effect-good effect, health, poor effect. Wearing masks is like people smoking.

4. Comfort. People who wear a dress are always bad. See who's more comfortable.

5. Suitable for the crowd-good for all ages.

6. Use standards-the old standards must be strict.

In addition, the old standard is a mandatory standard, and the manufacturer must strictly implement it; the new standard is a recommended standard, not necessarily strictly implemented, and the product still needs to meet the performance indicators of the old standard.

Through the above points, combined with the civil mask manufacturer's own publicity, summarize:

1, price -3M wins.

2. Brand 3m is better than 3m, but has strong stability.

3. The effect-the effect is not great.

4. Comfort-Stability is better than victory.

5. Apply to the crowd-stability is better than stability.

6. Adopt standard -3m wins.

Note: Current standards do not address older persons and children separately. Therefore, stable universal masks are only suitable for size. The suitability of the others is unknown and therefore cannot be considered a victory.

Conclusion: 3M wins

In fact, it can be simply seen that the products under the old standard still have their advantages. Therefore, it is recommended to purchase civilian masks under the old standards at this stage.

Regret for the new standard

1. The new standard only gives the level of protection. As for the filtering effect corresponding to the protection level, manufacturers also need to clearly state in the packaging that consumers are more sensitive to numbers, while the use level is not so intuitive.

The testing requirements of the new standard are lower than those of the old standard. Therefore, although the masks tested by the old standard have the same filtering effect, it is difficult to ensure that the actual effect of the two is similar.

The old and new standard testing methods are only applicable to adults. Therefore, the masks produced by the manufacturer are only suitable for adults, and do not involve infants, children and the elderly. This is what the new standard lacks.
