Is there such a thing as a direct filter of haze?

There is a kind of high-grade screen window imported from Japan that can filter fine dust, this kind of screen seems to be called ultrafiltration membrane screen, which has a layer of ultrafiltration membrane on the surface, which can filter the level of fine dust and purify the haze! Even if there is an air purifier at home, it must be equipped with ultrafiltration membrane screens to filter out the pollution sources outside the window, and the purification effect will be good. You can look for it on the Internet, it seems that there are some on the Internet.

It can be shipped nationwide, and it can be measured at home and the exact size can be done. JD Puweixin imported masks from the United States.

As long as you have it at home.

Before the air pollution control has not seen obvious results, what we can do is to purify the indoor air, it is very necessary to choose a qualified air purifier, many experts recommend the use of air disinfection purifiers, how to choose to remove and zero consumables without pollution 0 artificial air disinfection purifiers, now can achieve disinfection and sterilization of clean air only using super ion cloud technology air disinfection purifiers, when cleaning the air also avoids the production of ozone.

For example, the world's first patented product 'Siwan Air Automatic Disinfector', which is reported by authoritative testing institutions, can kill coronavirus, influenza virus and other viruses and bacteria, disinfect and clean the air, and eliminate haze and odor.

It is best to buy it for indoor use, which is more reliable and safe.

Smog means that the fog is relatively large, and there is a lot of dirt in it.

Smog is mainly composed of sulphur dioxide, nitrogen oxides, and respirable particulate matter. The first two are gaseous pollutants that combine with the fog to make the sky gray in an instant. Therefore, the smog purifier is required to be able to remove both chemical and harmful gases.

Ordinary haze filters can only filter particulate pollutants and have little effect on sulfur dioxide and nitrogen oxides, so on the whole, haze filters do not have much effect.

Smog removal requires an efficient and professional air purifier. Allerair is not only the number one in removing, but also in removing chemically harmful gases such as sulphur dioxide. Because AllerAir is an industrial air purifier, industrial air purifiers need to remove a variety of chemical harmful gases, and the type, concentration, and complexity are far from comparable to haze.

That's why AllerAir is very effective in removing smog. It has an anti-virus filter in each purifier, for example, a 6000 V anti-virus filter is kilograms! Therefore, the AllerAir with its dual efficiency in removing chemically harmful gases and removing it is far from being comparable to a haze filter, and is the best choice for smog removal.

Haze Haze is a combination of fog and haze. Smog is common in cities. In many parts of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively known as "haze weather".

Smog is the result of the interaction of specific climatic conditions with human activities. The economic and social activities of high-density populations will inevitably emit a large amount of fine particulate matter (pm, once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate, and if affected by static weather, it is very easy to appear large-scale haze.

Haze is the fine particles mixed in the fog, also known as but it is extremely harmful to the body, and there are carcinogens in it, so everyone must wear an anti-haze mask when going out.

A mixture of dust and water vapor in the air.

Fog is a mixture of gases, and smoke is a mixture of particles and solids. Smog is a solid mixture of fog and smoke, because those ppm level particles are usually not easy to see, but mixed with fog can be seen very specifically.

It's poisonous air, and Beijing doesn't have to go. Hurry up and come to Guangzhou for development. There is very little smog in Guangzhou. It does not affect physical health.

Caused by pollution, the air is seriously bad, affecting physical and mental health.

Smog is a gas caused by many toxins.

If you want to protect the haze environment, you need to do a good job of professional respiratory protection, wear a dust mask to protect against fine particles, the air leakage rate and protective effect of ordinary disposable masks are generally not too good protection, it is recommended to use a KN100 protection level mask.

If you choose a mask, it is recommended to choose a mask in the following way:

1. As a special labor protection product, dust masks must be certified by GB2626-2006.

2. Masks are divided into disposable and replaceable filter half masks and full masks. For long-term occupational protection use, it is recommended to use a replaceable filter cotton half mask. Occasionally, when you go out to work, you can choose a disposable dust mask.

3. The materials of the duplex half mask include silicone, plastic, etc., the silicone material is relatively soft and comfortable, and the facial pressure is low.

4. For dust and oily particles, protective masks are divided into oil-proof (oily smoke, oil mist, dust, smoke, fog, microorganisms, represented by KP) and dust-proof (dust, smoke, fog, microorganisms). For dust prevention, there are three levels of protection level: KN100, KN95 and KN90, the working environment is diverse in pollutants, and the harm to people is greater, it is recommended to choose KN100 level.

5. It is particularly important that the mask is divided into sizes according to the national standard. Many masks are not semicolonized, and the effect will vary from person to person.

6. There are two types of masks: covering the mouth and nose and covering the mouth, nose and jaw, of which the second type has a large contact mask, good sealing and low pressure sensitivity.

7. Choose one with low breathing resistance. The national standard stipulates that the inhalation resistance is 350 Pa, and some are only about 120 Pa, so breathing is smooth. Masks with high breathing resistance are easy to cause damage to the lung diaphragm.

Negative ions will be better to remove haze, air negative ions are due to the oxygen molecule adds an outer layer of free electrons, obtains a negative charge, so it has an extraordinary binding ability, so that the usually positively charged indoor floating dust, smoke (gather with each other, lose the ability to float freely in the air, and fall rapidly, thereby purifying the air, purifying the environment, and no longer forming a hazard to the human body. These ultrafine particles are difficult to filter out by general mechanical equipment, and air negative ions have a special ability to these harmful substances, the smaller the particle size, the higher the capture rate, is an effective way to eliminate this dust.

Bacteria, viruses, formaldehyde, benzene, VOCs, etc. in the air have a positive charge, and combine with negatively charged negative ions to become water and carbon dioxide, so negative ions can inactivate these toxic and harmful gases and bacteria.

The first is the physical base source for the generation of particulate dust. China has the world's largest loess plateau area, and its soil texture is the most prone to the formation of particulate dust particles.

The second is the dust caused by the movement of hidden relatives and jujubes. For example, if mud flows onto the road after rain or splashing water on the soil in the middle of the road and on the corner of the street, after an hour of drying, it will cause a large amount of dust to be whirled by the wheels, and even if these particles fall back to the ground, they will be thrown over the city again due to the continuous driving of cars.

Third, the dust-based source and the motion difference process are concentrated in a certain spatial range, and the particles eventually accumulate with the water molecule nodules to form haze. At present, among the more than 350 cities in the Loess Plateau region of China, the stock of the three elements of haze structure is quite abundant.
