There are many kinds of children's masks on the market, with different prices. How to choose a safe, effective and high-quality mask has attracted much attention. According to the recommended national standard of "technical specifications for children's masks" issued by our country, special provisions are made on the data, wearing, application and other indicators. When buying children's masks, these details should be "polished"!
1. Safety first
"The technical specification for children's masks puts forward 19 main performance indexes, including safety, protection, comfort, etc., with safety as the main premise." Li Lingshen, President of China Industrial Textiles professional association, said that two types of products, child protective masks and child health masks, have been standardized. When the filtration power of clear particles is not less than 95% and 90% respectively, higher requirements have been put forward for the selection of raw materials of manufacturers.
"Compared with adults, an important difference of children's masks is that they pay more attention to reducing the cardiopulmonary burden." A person in charge of TEDA clean company, a manufacturer of mask filter materials, said that a safe mask needs a strong "heart", that is, the melt blown cloth should meet the requirements of low resistance and high efficiency.
In the selection of non-woven fabrics, the mask raw materials should be standardized and clear, and recycled materials should not be used“ Production enterprises must not choose non-woven materials added with recycled materials or calcium carbonate fillers for low cost, which often have fluorescent agents. " Cao Jun, chairman of Lanhe medical, a children's mask manufacturer, suggested.
2. Pay attention to the ventilation performance of mask
In addition to the clear requirements for particulate matter filtration power and bacterial filtration power, the specification specifically proposes that the expiratory resistance and inspiratory resistance of child protective masks should not be higher than 45pa; The ventilation resistance of children's health mask should not be higher than 30Pa. In terms of wearing comfort, adjustable mask belt is recommended.
According to the "standard" purchase together, experts also give some intuitive basis for discrimination“ For example, children's masks that meet the protection requirements must be three-dimensional design, while ordinary health masks are mostly flat.
All masks on the market will be printed with GB / t38880-2020.

3. Buy the right way
"Because of the special types of masks, some children's masks that have reached the standard are limited to the" non-medical "category, and it is difficult to distribute them to pharmacies and other channels. It is suggested that relevant departments and institutions should supplement the recommendation strategies of children's masks in time, so as to facilitate the orderly connection between channel providers and manufacturers." Zhao Jinyu said.
Generally speaking, the qualified children's masks are neat in appearance, in good shape, and have no damage or stain on the surface; No peculiar smell and pungent smell; The name, category, specification, performance label, production date and shelf life of the product, or production batch number and restricted use date, manufacturer and whether it has been sterilized by ethylene oxide shall be clearly indicated on the outer package
4. Simple and effective
According to the new specification, children's masks should not be dyed when they are in direct contact with the skin, and their color fastness to dry rubbing should be greater than or equal to 4. It is also suggested that parents should try their best to reduce the risk of color fading by purchasing such masks with printing for children.
5. Children should wear masks under the care of adults
Children should not fight or exercise with moderate or above intensity during wearing masks, and should not disassemble the breathing valve and its internal parts.
If respiratory discomfort, skin allergy and other symptoms appear during wearing, the mask should be removed in time, and if necessary, seek medical advice immediately.
Children with dyspnea should not wear masks. When using, the objects irrelevant to the mask should be removed.
The mask should be replaced in time. It is suggested that children should carry 1-2 spare masks with them; It is not recommended to use the mask repeatedly after washing, and the used masks cannot be exchanged.
