Tips: How to choose a reliable anti-snoring mask?

Into the winter, the continued haze made the tamper-proof masks hot again. It is worth noting that on November 1st this year, the "Technical Code for Daily Protective Masks" formulated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, was formally implemented. So, what impact does this new national recommended standard have on the market for anti-mite masks? How should the public choose?

New standard affects geometry

The "Protective Masks for Everyday Protective Masks" clearly defines the effects and safety performance of fine-particle protection for masks. Among them, the mask protection level is divided into D grade, C grade, B grade and A grade from low to high according to the air pollution situation. They are applicable to medium and sub-pollution, severe and sub-pollution, serious and sub-pollution, and severe pollution, respectively. The corresponding protective effect of grades is not less than 65%, 75%, 85%, and 90%, respectively. After the consumer wears a suitable protective mask according to the standard, the inhaled air quality index must be more than good.

Although the new standard has been in use for some time, the reporter visited some pharmacies recently but did not find protective masks that meet the new standards. On some e-commerce platforms such as Taobao and JD.com, the reporter searched for tens of thousands of products with the keyword of “flood-proof masks”. The price ranged from 1 yuan to more than 100 yuan. The implementation standards for different brands of masks were also different. .

A person in charge of a protective mask manufacturer told the reporter: “There is a process for the implementation of the new standard. At present, companies need to digest the existing product inventory, and it will take a while to change the packaging again.”

Moth-proof masks

Faced with the wide variety of protective masks currently on the market, how should consumers choose?

"A lot of people think that wearing a mask can prevent smog. This is not the case." In the interview, some experts pointed out that PM2.5 refers to particles in the ambient air that are less than or equal to 2.5 microns in diameter. Traditional cotton masks have too many voids. Large, it can't block PM2.5 at all. In addition, the main role of medical non-woven masks is to block droplets and splashes, and its particulate filtering effect is very limited, only to play a general role in shielding.

"Generally speaking, the PM2.5 filtration efficiency of flood prevention masks should be at least 90% or more effective," said Chen Xinran of Zhengzhou CDC Business and Emergency Office. The reporter learned that most of the common anti-caries masks on the market today are based on American standards that begin with N or European standards that begin with FFP. According to experts, wearing a mask that conforms to the N95 standard can effectively filter more than 95% of particles in an environment where the concentration of PM2.5 is 500 μg/m3, which can provide better protection for the human body.

Therefore, when consumers purchase protective masks, they must observe the packaging more to see if they have clearly defined and approved mask implementation standards, such as “N95” and “FFP1”. In addition, experts suggest that white masks should be used as much as possible to prevent the decomposition of carcinogenic aromatic ammonia in some undesirable dyes and to reduce health risks.

Anti-mite can not rely on masks alone

Wearing a protective mask can prevent haze, but wearing too long is also not conducive to health. “A lot of masks have small pore diameters, and prolonged wearing can easily lead to hypoxia. Elderly and cardiovascular patients need special attention,” said Zhang Hao, the attending physician at Zhengzhou People's Hospital. Experts also reminded that after long-term use of protective masks, the filtered particulate matter will gradually block the filter material, resulting in reduced protective effect, increased respiratory resistance, and increased health problems. Therefore, the protective inserts in disposable masks or cotton masks should be discarded after a period of use, and should not be reused after cleaning or disinfection.

In addition to the correct use of respirator masks, experts also recommend that in severe haze weather, you should minimize the number of doors and open windows. When entering the room from outside, wash your face, rinse your mouth, and clean your nose. In terms of diet, eat less pungent foods and eat more fresh vegetables and fruits.
