There are 霾 霾 霾 选购

Since the beginning of winter, the anti-mite mask has become a must for some citizens. At present, there are many types of anti-mite masks in the market, and the quality of the products is uneven. A large number of products are marked with the words “anti-fog mask” and “PM2.5 respirator”. Relevant departments remind consumers to be cautious when purchasing anti-mite masks.

Recently, in the quality and safety sampling inspection of the anti-mite mask products organized by the Shandong Provincial Quality Supervision Bureau, 9 of the 20 samples purchased by the staff from the market did not meet the relevant requirements, and the failure rate was 35.3%. What should consumers pay attention to when choosing a mask?

The relevant person in charge of the Scientific Research Center of Shandong Provincial Quality Inspection Institute said that the effective and effective anti-mite mask should conform to the national standards, and pay special attention to the standard number and the protective effect level of the product on the product label. The protective effect reflects the barrier property of the mask product as a whole in the actual use process, especially the barrier ability of the mask at the gap with the face surface.

According to experts, whether the protective effect of the mask is up to standard, there is a simple method of judging: After wearing the mask, the public wearing the mask glasses can basically judge that the protective effect is not good if the lens is fogged.

At present, there are mainly one-time anti-smashing masks and double-type anti-smashing masks on the market, and the two are cost-effective. Engineers from the Scientific Research Center of Shandong Provincial Quality Inspection Institute reminded that the protective ability of PM2.5 masks is obviously affected by the material of the cover, especially the masks with knitted fabrics as the cover material. The filtration efficiency and protective effect indicators are difficult to meet the actual requirements. It is recommended that consumers buy masks of non-woven or silicone material as much as possible.

However, the higher the purification level of the anti-smashing mask, that is, the stronger the barrier property of the filter element to the particulate matter, which is likely to cause difficulty in breathing. For children in development, wearing adult anti-mite masks may cause breathing difficulties and allergic reactions.
