do you know? About 68% of diseases are related to air pollution. The human body takes about 20 breaths per minute, 28,800 breaths per day, and more than 10,000,000 breaths in a year.
So it became popular to use air purifiers, but do you really know about air purifiers?
01 – Why do you need an air purifier?
Many people have a misunderstanding when using air purifiers. They think that there is no need to open an air purifier if there is no smog. In fact, this is not the case, experts reminded that although the frequency of smog is low in spring.
But air purifiers are more needed in spring than in winter, because the composition of the air environment in spring is more complex, causing more health effects or harm to people.
The reasons are as follows:
Many people with allergies are miserable in spring, when the flowers bloom and the pollen concentration in the air is very high. Coupled with the strong wind blowing, many people who are prone to allergies will experience symptoms such as redness and itching of the skin, constant sneezing and other symptoms of pollen allergy.
If you stay in this environment for a long time, it is not good for the skin and respiratory tract. So in spring, people with allergies actually need an air purifier more than in winter.
2.Bacteria and viruses
With the rise in temperature and the recovery of all things, not only animals and plants have become active, but even the reproduction and growth of bacteria and viruses has begun to accelerate.
At the same time, spring is a period of high incidence of various infectious diseases. People with weak resistance, such as the elderly, children, and pregnant women, are most vulnerable to epidemic viruses.
We are all used to the kind of heavy smog that we can’t see, as if only that kind of smog counts as air pollution, but we ignore the harm of mild pollution to people. Although light pollution is not easy to be detected by people, its impact on people will not be reduced in the slightest.
4.Formaldehyde exceeds the standard during the decoration season
The friends all know that the decoration season officially begins after the spring of each year. Even if there is no need for decoration in your own home, your neighbors will definitely have it. In this way, no matter who is decorating, formaldehyde is still by our side.
You must know that the formaldehyde content in the decoration materials is amazing. If you are not careful, you may inhale too much, and the damage to the human body is irreversible.
In fact, to put it a bit harsher, an air purifier is like a vacuum cleaner, which helps you collect all the garbage in the air. This is the most important role in my opinion.
02 – How does an air purifier work?
The principle of the air purifier is actually very simple. Just put a filter with a suitable density in front of the fan, and then the fan will extract air through operation, and the filter will leave the magazines or pollutants in the air, and then it will be fresh and pollution-free. air is discharged.
From this, it can be concluded that the efficiency of the air purifier = the speed of the fan extraction ✖️ the efficiency of treating the exhaust air ✖️ the efficiency of the filter.
The size of purification efficiency is the primary factor in purchasing an air purifier!
Consumers cannot judge the purification efficiency of an air purifier from the appearance. Therefore, the state stipulates that the CADR value must be marked on each air purifier. The unit of CADR is m³/h. At the same time, two different products The higher the purification rate, the better.
