The only thing we can think of about air pollution is smog. I remember that the smog should have arrived so quietly in 2012, but it would only last for 1-2 days and then end until 2016. Smog has begun to seriously infringe on our health in Beijing, Hebei and other places. Due to the continuous media coverage of haze, "pollution = PM2.5" has become a fixed mindset in the minds of many people. This "formula" can still be established in the outdoor environment, but the pollutants in the indoor environment are not that simple. Formaldehyde, benzene, TVOC and other decoration pollutants have become the main sources of pollution in Chinese families. This is also the case in my country and abroad. Key differences in pollutants in the home environment.
We are exposed to a lot of air pollution. Let’s put aside heavy pollution such as industry for the time being and start with the pollution we are frequently exposed to in our daily lives, such as:
1: PM2. 5 and smaller particulate pollutants
2: Formaldehyde, benzene and other decoration pollutants
Although air purifiers are the main way to solve pollution, when we choose and buy We must also be targeted. First of all, we must have a general understanding of the pollution situation in our home: Which type of pollution is more serious in the indoor environment? Which air purifier do you need more? Only by understanding these issues can you make targeted purchases to obtain the best purification effect. Here, the editor actually conducted an actual test of the purification effect of an air purifier.

Since it is aimed at air pollution The most effective thing is an air purifier rather than holding your breath. So let me tell you what are the "tricks" in air purifiers. First of all, looking at the working principle of air purifiers, they are mainly divided into three types: Passive type. , active, active and passive hybrid. According to the technology of air purifiers for removing particulate matter in the air, there are mainly mechanical filter type, electrostatic electret filter type, high-voltage electrostatic dust collection, negative ion and plasma methods, etc. According to the purification needs, air purifiers can be divided into purification type, humidification and purification type, vehicle-mounted type, desktop type, large and medium-sized, and central air-conditioning type.
The continuous foggy weather since 2016 has caused headaches for many people, and the word "haze" has quickly occupied the top of Baidu's search rankings. A "small outbreak" of air pollution has ushered in a wave of sales growth in the always bleak air purifier market. Even the samples displayed in offline stores in many cities have been sold out, which shows that users are very concerned about indoor air quality. Pay attention to.
Most of the air purifiers placed in the homes of friends I know are humidification and purification types, purification types, and desktop air purifiers. So here comes the key point, can buying an air purifier effectively control air pollution? We can’t help but ask, is the purifier we spent a lot of money to buy really useful? Many people have many misunderstandings when purchasing purifiers. Today I will talk to you about the problems that are easily encountered when purchasing and using purifiers.
What precautions should be taken when using the purifier?
As the author said before, the air purifier is not a disposable consumer product, and its purification effect is reflected in long-term use. The purifier we buy is not a one-and-done thing. Once it is used improperly, it will cause secondary pollution. At the end of the article, the author will take stock of the very important precautions when using the purifier.
①Purifiers that have not been used for a long time need to be thoroughly cleaned before starting again
Since the pollution in spring and summer is not too serious, many families leave the air purifier aside for about half a year. Wait until the haze is serious in autumn and winter before taking it out for use. However, you need to pay attention before use. In addition to wiping the dust on the surface and air outlet, you should also check the use and cleanliness of the filter. Use a vacuum cleaner to carefully clean the pre-filter. For activated carbon that has not been used for a long time, The filter can be dried to maintain the purification effect. The HEPA filter needs to be replaced according to the recommended replacement time and usage stated on the product label.
Electrostatic dust collector air purifiers are relatively simple to clean. You can use a brush to clean the dust inside and at the bottom of the machine. The internal dust collector can be cleaned with water and allowed to dry before continued use. In daily use, you should also pay attention to cleaning the dust collector regularly to avoid secondary pollution.
②The HEPA filter needs to be replaced regularly
In such a severe haze environment in autumn and winter, the HEPA filter is consumed very quickly. If it is not replaced or maintained for a long time, it will Not only does it fail to purify the air, it also becomes a breeding ground for bacteria and other microorganisms, threatening the health of users.
As for how often to replace the filter, we can refer to the recommended replacement cycle given by the purifier official, but we cannot just stick to the old rules. If the pollution is too serious, we can consider replacing the filter in advance. When purchasing, try to choose original consumables with more guaranteed quality to avoid problems such as unsuitable models or poor purification effects of counterfeit filters. Try to wear a mask and gloves when replacing the filter to reduce the risk of inhaling particulate matter.
In short, air purification is by no means a one-day effort, nor can it be done once and for all by buying a purifier. In order to obtain the best purification effect, you must first be aware of the types of indoor pollutants and select purification products in a targeted manner. During use, you need to pay attention to regular maintenance and cleaning to maintain the best working condition of the purifier. In addition, it should be noted that the HEPA filter cannot be cleaned and reused. It can only be replaced once the specified service life is reached.
When talking about this, the editor encountered a very embarrassing thing. For the time being, we will use the best essence effect of a large air purifier. It will take about 90 minutes to achieve the desired indoor purification in a room of about 20 square meters. For a healthy air environment, if you open windows or doors, you need to extend the purification time, and the air environment during this period is not healthy. What should you do? Then let’s talk about desktop air purifiers.
You can easily understand the desktop type air purifier from the literal meaning. The so-called desktop type means that it is small and can be conveniently placed on the table. What I mean is that the purification effect can only be used by one person. . Many desktop personal air purifiers pass fresh air directly to your mouth and nose, which means that you can enjoy the filtered fresh air within three seconds of turning on the machine. Maybe some smart friends have already thought of it, since the air effect in the house will be affected by opening the door and opening the windows. Therefore, we can use a large air purifier to purify the breathing environment, and then use a desktop personal air purifier to adjust the quality of the inhaled air.
The editor can introduce several desktop air purifiers to you here. Of course, we still have to consider many aspects, such as: filter, appearance, purification effect, personal usage rate, etc. What are the products on the market? The relatively good ones include Panasonic, Philips, Haier, Samsung, and Panda. Of course, we have to start from an economic perspective. After all, it is a secondary air filtration product. If the cost is too expensive, the gain will outweigh the loss, so it is better to buy a more expensive one. A cost-effective large-scale air purifier.
