Please recommend anti smog masks, recommend a few more, thank you!

There are many kinds of anti-smog protection, from safety, economy, and comfort to choose from.

Because the haze contains a large number of harmful particles, the smog is to do a good job of respiratory protection for your health. Choose a dust mask scientifically, choose a good mask with good protective effect, smooth breathing, and economical use. Helps prevent respiratory injuries from occurring.

Now masks must comply with the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90. Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust (particle size microns).

If the granularity is large, KN95 grade can be selected.

The protective effect of dust masks depends on 2 aspects. One is the filtration efficiency of the filter cotton. The second is how tightly the mask is combined with the face.

Therefore, masks must be divided into large and small sizes, and the fit effect of masks and faces varies from person to person.

The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.

2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

At present, there are KN100 grade products in China, and the comprehensive use cost is about one yuan per day.

Langqin masks are not bad, last year's smog was too serious, I was afraid that the child would get sick, so I quickly bought one, and Langqin looked more reliable when I picked it up, and the child liked it too. After using it for about two or three months, it was still quite good, and the child said that it was not easy to breathe. The filtration effect is still obvious, and a layer of ash will be filtered off the filter cotton in one day.

This thing is good for children, parents should buy it as soon as possible!

Langqin, his family's advantage is children's models, and when he bought it last year, only his family had children. Professionally do children's. 3M, 3M was first recognized by China in the early 80s of the last century, when many disks used to store data were 3M products.

The large-scale "brand promotion" was during the "SARS" at the turn of the spring and summer of 2003, and the N95 masks produced by 3M became people's collective memory for a while.
