1、 Importance of air purifier
Air is closely related to human survival. It directly participates in the processes of gas metabolism, material metabolism and temperature regulation of the human body. However, throughout the world, air pollution is everywhere, not to mention other important diseases. Haze in the north and dust and pollen in the south are enough to affect human health.
In addition, in recent years, the epidemic has been repeated, and everyone spends almost every day in the life of wearing a mask. Air purification has become the top priority in our life. After all, physical health is the capital of revolution, and breathing fresh air can keep us away from more diseases!
The birth of air purifiers is really a great benefit for people, especially for the elderly and children with weak immunity at home. Air purifiers are even more important!
There are many kinds of air purifier products on the market. If you don't master the core knowledge of shopping, it's easy to buy IQ tax products at a high price.
Therefore, the more expensive the air purifier, the better? Can all air purifiers remove particulate matter and formaldehyde? The answer is: no!
Today, let's take a look at how to choose a satisfactory air purifier with a keen eye! Don't be led by the advertisements of some businesses!
2、 Core points of purchasing air purifiers
Cadr value: refers to the amount of clean air, that is, the purification efficiency, generally refers to the volume of air that can be purified per unit time. For rhinitis patients and new arrivals, special attention should be paid to the gas value of Cadr! The higher the Cadr value, the faster the purification speed and the higher the efficiency!
CCM value: refers to the cumulative purification capacity of an air purifier, which can be simply understood as the service life of consumables, which theoretically determines the service life of an air purifier.
One point to emphasize here is that the higher the CCM value, the longer the service life of the filter screen! But here, I still suggest that the filter element can be replaced every 6-12 months, otherwise the cleaning ability of air purification will be greatly reduced. Some activated carbon adsorption air purifiers claim that the filter element can be used for three years. In fact, "usable" and "effective" are two different things~
3. Noise value: for those with old people and children at home, the lower the noise value, the better. It will not disturb the rest of the family. This is like the noise of an air conditioner, which really affects the host's life experience, so low noise is an important indicator for choosing an air purifier.
4. Filter composition: the richer the filter composition, the better, and the more comprehensive the function of removing formaldehyde, virus, odor and so on. Like the unitary filter screen, it is generally composed of activated carbon + HEPA filter screen, and the purification function is relatively single. It is recommended to select composite filter screen, which is generally composed of primary effect filter screen, activated carbon filter screen and HEPA filter screen, and the purification effect is more comprehensive and efficient! We should make a comprehensive evaluation in combination with the composition and function of the filter screen when purchasing!
In these points, we should be careful. Some brands often make a big fuss about Cadr values, but ignore CCM values and noise values. We should know that a good air purifier is far from enough to have Cadr values alone. It must meet multiple index values at the same time, and none of them is indispensable!
Conclusion: to buy a practical air purifier with high cost performance, you must choose one with high Cadr value, high CCM value and low noise value. It will be more perfect if you combine the above main purchase parameters with other bonus items.

How to distinguish different indoor pollutants?
It was found that many owners would come to consult about smell after indoor decoration. Some have been newly renovated for several months, and some have even been renovated for several years. They can smell "decoration" in the closed room. What is the taste of decoration? How to distinguish different indoor pollutants? 1. Formaldehyde is a colorless, tasteless and irritating gas Formaldehyde is colorless and tasteless in a strict sense, but when the concentration exceeds 3 or 4 times, it will stimulate and damage human mucosal tissues, such as sore throat and inability to open eyes. But this is not the main danger. The main hazard is that formaldehyde rapidly enters the blood through the alveoli through the respiratory tract, causing incalculable harm to the human body. Formaldehyde mainly comes from artificial wood used as decorative materials, such as adhesives in plywood, core board, medium density fiberboard and creative board (particleboard). So usually, the simple smell we smell is not caused by formaldehyde, even if formaldehyde exceeds the standard by 1-3 times. 2. Benzene is an aromatic gas The smell of benzene is fragrant, and some people feel like the taste of bitter almond. Therefore, many experts call it "fragrance killer", as long as the source of benzene is paint, especially oily paint. Benzene also has other uses, that is, artificial fragrances and essence may contain benzene. 3. TVOC is the general name of organic compounds in the air Usually, the smell you smell when you decorate is TVOC, because it contains eight kinds of organic compounds. However, there are also cases where VOC seriously exceeds the standard, but there is no task odor indoors. The main sources of volatile organic compounds are paints, adhesives, fabrics, textiles, etc., and some of them come from the incomplete combustion of coal or tobacco. Ammonia is a kind of malodorous gas In our daily life, the smell of ammonia is the smell of fertilizer. Colorless, but highly irritating and smelly. If you live in a city and don't know the smell of fertilizer, you should be exposed to the unpleasant smell of public toilets in summer. Ammonia is mainly used as an antifreeze in cement, usually appearing in the north, but rarely exceeding the standard in the south. Radon is a colorless and tasteless inert gas Radon gas is formed by radium radiation decay from marble and granite. It is colorless and tasteless. Because it is an inert gas, it will not react with any organic matter. Their presence cannot be distinguished by sight and smell, and they can usually be detected by special institutions.
