Which brands of n95 masks are better to use?

Medical surgical masks can be used for daily protection. If you go to hospitals and other high-risk places, it is recommended to wear N95 medical protective mask. If conditions permit, it is recommended that both kinds of masks be prepared at home.

Today, I recommend five popular and easy-to-use N95 medical protective masks, with filtration efficiency ≥95% and excellent protective effect, which can be purchased on demand.

1.3m medical N95 mask 9 132

During the period of 1967, American 3M company mastered the proprietary technology of non-woven fabric and electrostatic fiber cotton filtration, and began to produce anti-particle masks, from which came the internationally recognized NIOSH mask standard.

9 132 is a medical N95 mask, which has passed the N95 certification of NIOSH in the United States and the certification of the US Food and Drug Administration in China, and conforms to the national standard GB 19083-20 10 medical protective mask, which is different from the industrial N95 mask. Ordinary people can choose to prevent COVID-19, whether it is medical N95 or not. The People's Daily also affirmed the protective significance of N95 mask for preventing particles in the mask usage guide.

3M, medical N95 mask, very close to the face, with good protective effect. Suitable for front-line workers, the price is about 15 yuan/piece.

Experience:

9 132 inherited the rubber headband and metal fixing nails handed down from 3M. The elasticity of rubber belt is far greater than that of webbing, and it is tightened tightly, which can provide better sealing performance. Fixing nails is safer than welding (rubber belts cannot be welded by ultrasonic wave). When I used some big-name head-mounted masks with webbing and welding technology, I encountered the situation that the solder joint was broken when I put on the headband, but it was not 9 132.

9 132 aluminum nose bridge is much harder than 950 1+/9502+, and the setting is also more laborious.

2. Stabilize N95 medical protective mask (sterilization grade)

Steady medical care is the parent company of the cotton age. It started as a medical dressing and is now the largest mask manufacturer in China. Deeply cultivated in the mask field for 30 years, it will be listed in 2020, which can be described as the industry benchmark.

The stable medical protective mask is a kind of head-mounted mask, which fits the face better than the ear-hanging mask and is suitable for medical working environment. The mask conforms to the national standard GB 19083-20 10 "Medical Protective Mask", and the filtration efficiency is ≥95%, belonging to 1 grade product, which can block particles, droplets, blood and body fluids in the air.

Masks should be used as soon as possible after opening, and independent packaging is more advantageous. 1 bag 1 medical protective mask costs about 1 1 yuan.

How to experience:

Distinguish the inside and outside of the mask, up and down. Don't squeeze the mask with your hands. N95 mask can only isolate the virus on the surface of the mask. If you squeeze the mask by hand, the virus will soak through the mask in the form of droplets, which is easy to cause virus infection.

Try to make the mask fit your face. The simple test method is: after wearing the mask, exhale forcefully, and the air cannot leak from the edge of the mask. The protective mask must be close to the user's face, and the user must shave off his beard to ensure that the mask can be close to the face. Beards and anything placed between the mask gasket and the face will make the mask leak.

After adjusting the position of the mask according to your face, press the nose clip along the upper edge of the mask with the index finger of both hands to make it close to your face.

3. Notoginseng N95 medical protective mask

Sanqi is a national brand in China, and its popularity overseas is not less than 3M. During the fight against the COVID-19 epidemic, the story of Sanqi was also published in People's Daily. Sanqi, as a professional mask manufacturer, has been audited and certified by many countries since 200 1.

4. Kangaroo Doctor N95 medical protective mask

According to the statistics of many spot checks by national and local quality supervision departments, the qualified rate of kangaroo doctors' masks is high and the quality control is stable.

Kangaroo doctor's medical protective mask meets the national standard GB 19083-20 10 "Medical Protective Mask", and its filtration efficiency is as high as 99%. It belongs to the second-class medical protective mask and can effectively block virus particles such as influenza. Like 3M 9 132, this model has a dome-shaped three-dimensional shape, and its facial fit is stronger than that of the willow leaf used for Heino protective mask. At the same time, it can effectively reduce the internal pressure of the mask and provide a more comfortable breathing effect.

Kangaroo doctor's medical protective masks are packaged separately, each 5-6 yuan.

Experience:

The quality of workmanship is very good. The black surgical mask feels thicker than the blue one. The outermost non-woven fabric has a good waterproof effect and the overall workmanship is very good.

Very cost-effective. On the basis of maintaining the above performance, the price of this mask is generally within 10 yuan per package. When purchasing, you can compare platforms such as JD.COM and Taobao. There are often promotions, and it is more favorable to buy more. General 10 package bought together, evaluation 2-one package in 3 yuan. The unit price is 1-3 cents each.

Good use experience

In the process of use, the mask is quite large, and it can be wrapped well after wearing, which can protect the left and right sides. Then the protective effect is better, the breathing is smooth, and there is no special feeling of stewing.

5. Heino N95 medical protective mask

Heino 20 18 began to produce medical masks, which entered the market late. However, it is one of the few enterprises that have obtained the qualification of producing second-class medical devices, and the production conditions are complete, from the raw materials of masks to the accessories with nose clips, all of which are controlled by themselves.

Heino protective mask meets the implementation standard GB 19083-20 10, and the filtration efficiency is over 95%. Each mask is packaged independently after being sterilized by ethylene oxide, which is more sterile and reassuring. The length of the third-gear ear strap can be adjusted to support a variety of wearing methods.

This product has two specifications: adult model and children model. Adults and children can fit the face well and achieve the protection effect.

Experience:

Three-dimensional design, face modification: Although it is a three-dimensional design, compared with the two introduced two days ago, the effect of face modification is not so prominent. Does it look like a duck's mouth?

Four-layer filtration protection: double-layer melt-blown cloth, double-layer non-woven fabric, layer-by-layer protection, which can effectively block droplets and air pollutants, making it more comfortable to wear when going out!
