The lingering smog not only prospered the air purifier market, but also made the mask market flourish. Masks once became an "artifact" against haze, and there was also a "mask fever" in China. In this regard, the reporter launched a series of investigations on the current situation of the mask market.
Nearly half of the masks have low filtration rate.
The sampling masks are mainly from major e-commerce platforms, and the prices of the sampling masks range from 1 yuan to 47.8 yuan. After testing, among 100 samples, nearly 50% of the mask samples have a low degree of filtration and fail to meet the purification standards. It is difficult for masks with low filtration rate to effectively protect the respiratory tract, and inhalable particles and various dusts in the air will directly enter the human body through masks. Professor Zhang from the Health Medical Center said that the filtration rate is the basic standard for testing the quality of masks. Wearing a mask with low filtration rate is equivalent to the respiratory tract directly contacting the outside air in foggy days.
A mask that doesn’t conform is equal to wearing it for nothing.
Here, we want to talk about a word, that is, "leakage rate", which is different from "filtration rate". Leakage rate refers to that harmful substances directly enter from the gap between the mask and the face, and thus are breathed into the body. In this inspection, the reporter found that almost no masks on the domestic market can achieve 100% fit with the face. "The fit of masks is the most important part for businesses, which not only affects the comfort of the face, but also affects the use effect of masks." The head of Freka, a famous British mask brand, said that as the most popular mask brand in Britain, one principle of Freka’s mask design is to achieve a 100% fit rate. For this reason, Freka hired famous human engineers and designers to complete the design work of each mask, and specially launched a variety of products such as Wing (mask outline), Insert (inner core) and Filters (filter cotton). In recent years, Flaka has become a leader in the mask market by virtue of its unique advantages.
Expert advice: Don’t try to buy useless masks cheaply.
According to the current situation of the mask market, Professor Zhang said that although there are many kinds of masks on the market at present, the prices are generally very cheap, but consumers should still be reminded not to buy masks that are not available for a while. When purchasing masks, consumers should pay attention to the high degree of fit between the mask and the face, and can choose such as cup, butterfly and fish shape according to their face shape.
