As a commuter must wear an industrial protective mask every day, answer it with personal experience . I use a 3m2097 filter with a 3m7502 half mask.

One: The price is not expensive

3m7502 standard 6001cn filter box has a long service life, but unfortunately a bit heavy. I replaced it with 3m2097, which can be bought for 35 yuan on Taobao. According to the instructions, in order to protect against oil pollution, 3m2097 can be used for 40 hours or 30 days.

For the street environment, I think we can slightly extend the use of time. In addition, users have discovered that the two pairs of filters are used interchangeably, which can greatly extend the service life. When not wearing, the oily odor will naturally evaporate. Even if it costs 5 cents a day. Therefore, from the perspective of price, industrial gas masks are less expensive than N95 masks.

Two: The effect is wonderful

1) I wear a lot of N95 masks. In principle , it only protects against dry dust and does not protect against oily pollutants. The carcinogens on the streets are polycyclic aromatic hydrocarbons. They are emitted from motor vehicles and are not only oily pollutants. Mostly in a gaseous state.

2) From the use of experience , N95 masks can not isolate the smell. And take 3m2097 to go to the public toilet, go for the hot peppers, ride the bus and follow the bus..... You can't smell anything. 3m2097 is not N95, but P100. It not only isolates 99.7% of dry and oily particles, but also absorbs various odors.

3) The excellent design can isolate the moisture in the breath and protect the life of the mask. The N95 mask will make the filter water-absent when sweating and exhaling. Actually, non-woven fabrics used for filtration can theoretically be used for a long time without regard to oily pollution, and can always be used to collect a large amount of particles and you feel uncomfortable to breathe. But it can't touch water, it will fail if it gets wet, it won't dry, and the internal structure will be destroyed. The gas mask considers the problem of waterproofing. There are two one-way breathing valves. The breathing chamber is isolated from the air intake compartment and effectively isolates moisture.

Three: Not stuffy, not stuffy

Netizens wear it to ride and commute without any problems. I myself have been wearing it for two years. I also tried wearing it and jogging to lose weight. Of course, it would be a bit more boring than streaking.

Four: Onlookers mood stability

I have been wearing it for two years. I used it to walk across the streets of Hangzhou over 700 days and nights. I even intentionally wore it on foot. People who came face to face didn't have any strange expressions, let alone stare.

Of course, for a long time, there will be special extroverts who can not restrain their excitement. Once a 6 or 7 year old boy sat behind his mother's battery car and turned his head at 180 degrees, staring at me for more than 10 seconds. Then he jerked back and tried to lick his mother's arm: "Mom and mother! I also want to buy one like this!"

The first time I was called up was a couple of boys in colorful suits. They overtook me and looked at me with a red light. They gathered me and pulled down the masked riding hood and asked what I was wearing. Where to buy, how much money.

Five: The previous figure

To correct a cognitive error, it is not only PM2.5 in the air that is harmful to your health. PM2.5 is also an air index that aims to tell you the level of air quality. In general, when PM2.5 is high, other harmful components will increase.

In a sense, if an environment needs to wear N95 series masks, it is already extremely bad. N95 masks are not friendly at all for those who are frail and have difficulty breathing. If they are properly worn, they will suffer from poor breathing. If some areas in Beijing reach 800, the frail people should rest at home and not go out, and not to mention whether you can bring N95, that is to say, can stop, only one thing can be stopped, and there are other things. The ingredients are waiting for you. Therefore, it is not a question of whether or not it should be brought. It should not be a problem that should go out.

For gas masks, it is not recommended for ordinary people to wear, filter box purchase, maintenance, etc. have requirements, some strict management companies will even require the right amount of people to have the right to wear gas masks. So, if you need to wear gas masks, move ahead.

In addition, regarding N95, it is estimated that a lot of people bought it, and when wearing it, please pay attention to wearing it tightly (such as whether it is completely on the face and whether the nose is handled properly). Pay attention to moisture, do not wash. This thing has a service life, generally about a week to get a new one.
