If the outdoor air is not good, you need to wear a mask, what masks can prevent smog?

As we pay more attention to air pollution, we will now start to choose masks, so how should we choose masks? Let's find out more about it!

Myth 1: Can a scarf be used as a mask?

On smoky days, many citizens wear masks to protect themselves when they go out, but some prefer scarves to masks for convenience. In fact, scarves, like ordinary cotton masks, have little filtering effect on harmful particles, such as them

Myth 2: Just buy a mask for surgery in the hospital to prevent smog?

Medical masks are actually divided into medical surgical masks and medical protective masks. The latter effectively protects the particles. Surgical particulate matter prevention masks.

This process requires sterility. The function of a surgical mask is to prevent the surface of a surgical wound from being contaminated by droplets produced by the doctor's exhalation or speech. Its function is to protect the patient.

Myth 3: German labor protection regulations stipulate that you need to take off your N95 mask for more than half an hour and breathe freely for more than half an hour?

German regulations. BGR190) does require a time limit for the use of respirators in the workplace, but the regulation is purely based on the requirements of insurance terms and only applies if the employer requires the employee to wear a respirator in the workplace. The terms of this insurance are based on the expectation of high-intensity work for employees, and the breathing resistance of the respirator will affect the high-intensity work.

However, on the other hand, if the mask is dirty, damaged, deformed, or has significantly increased breathing resistance, it should be replaced promptly.

Learning how to wear a mask is key!

First, choose the one that suits your face shape.

Secondly, after putting it on, you should attach it to your head and pinch the small nose clip on your nose.

Third, do a blow test. If there is no air leakage, protection is in place.

The above are some of the measures we take to wear masks with bad air, I hope it will help you!

When the body is sick, the heart is weak, and external evils are multiplied. And the heart is weak and weak, every time the heart and soul are disturbed, the real body is not full, and all kinds of uneasiness are found. Gluttony.

The effectiveness of a protective mask depends not only on the filtration efficiency, but also on the overall function of the mask.

The medical mask can prevent droplets, but its fit is not good, and the medical mask can only prevent PM4 at most;

Therefore, when traveling on hazy days, it is best to choose a mask with a breathing valve, good airtightness, and better material.

The testers obtained data and found that the real filtration effect of a 499 yuan product is that the anti-smog effect is only 67%. The actual test of a mask that costs only 7 yuan has a filtration effect of 97% and an anti-smog effect of 79%.

When traveling on smog days, it is best to choose a mask with a breathing valve, good sealing, and better material.

The product also does not meet the standards of any authoritative particulate matter protective respirator (such as meeting China's GB2626-2006 standard and has been certified by an authoritative organization), so it cannot be confirmed that these masks can really be prevented.

1. Wearing a mask can prevent smog.

When wearing a mask, it can reduce the exposed area and filter the pollutants in the air, so it can prevent smog. However, wearing a mask to prevent smog requires caution in the choice of masks, and not all masks have the effect of preventing smog.

2KN90 and KN95 masks.

If the mask has a filtration capacity of 90% for fine particles with a diameter of less than or equal to microns, this mask is called a KN90 mask, and if the filtration capacity reaches 95%, then it is a KN95 mask. This professional mask can effectively prevent smog and virus, correspondingly, the breathability of this mask is not good, and if the breathing rate is too fast, it is easy to cause poor breathing.

Expiration date: 40 hours 1 month, not washable.

Solemnly note: The wearing of KN90 and KN95 masks needs to be carried out under the guidance of a professional doctor. Children, the elderly, special populations with respiratory and cardiovascular diseases should be carefully selected.

3. The gauze mask can only filter large dust particles, which is suitable for use during cleaning work.

Expiration date: one-time.

Medical masks refer to masks worn when patients have cold, fever, cough and other respiratory symptoms, and can also be used as anti-flu masks in crowded and poorly ventilated public places.

Expiration date: one-time.

Activated carbon mask can adsorb organic gases and toxic dust, adsorb toxic gases or acne on the surface, and will begin to release toxic gases and acne after adsorption saturation, which does not have a bactericidal effect, and should be replaced immediately when it is necessary to breathe hard or cannot absorb peculiar smells, and is only suitable for painting operations or spraying pesticides.

Expiration date: one-time.

4. Anti-smog should also be worn indoors.

Many people wear masks outdoors and take them off when they are indoors. However, the impact of smog on the environment will also pollute the indoor environment, and if the indoor haze environment is not effectively improved, wearing a mask during a short outdoor trip is not of great health significance.
