Pay attention to respiratory health during epidemic period,Air purifier can really help

Since the outbreak of novel coronavirus pneumonia, not only the demand for anti viral materials such as masks and alcohol has increased dramatically, but also the concern of indoor air health has been aroused. On January 3, the reporter visited the local home appliance market and found that due to the impact of the epidemic and the improvement of consumers’ health awareness, the market heat of air purifier is rising. How should consumers choose the right one? In the process of interview, the insiders gave corresponding suggestions.

Change of consumption consciousness and attention to respiratory health

“Affected by the epidemic, more and more consumers are aware of the importance of air purification equipment. In the second half of this year, the sales volume of our air purifier increased by 68.8% year on year. ” Recently, Guo Jinchang, general manager of Qingdao daoyikongyou Technology Co., Ltd., told reporters that during the epidemic prevention and control period, most people stay at home longer, and the indoor air quality directly affects the comfort of the home. To a certain extent, it also further improves consumers’ attention to air quality, which can be seen from the sales volume.
It is understood that the sales of air purifiers are also “linked” with air quality, and the sales continue to rise when haze weather occurs frequently. In addition to the increase in sales of air purifiers, vehicle purifiers, portable fresh air fans and other products are also liked by consumers.

Is the air purifier really useful?

As “air conditioner”, many people are concerned about the purification effect of air purifier. During the visit, the reporter learned that there are many types of air purifiers. The traditional air purifier uses the filter screen to filter dust to purify the air, and the filter screen needs to be replaced regularly. Nowadays, the air purifier on the market has evolved from the traditional single removal of formaldehyde into a multi-functional one, including filtering smoke, dust, pet hair, sterilization and humidification“ Most of the air purifiers on the market can not effectively block the virus, so we need to purchase purifiers with ultraviolet sterilization function and photocatalyst filter screen. ” Guo Jinchang said that New Coronavirus was not discovered for a long time, lacking relevant research, and the air purifiers on the market were different in implementation standards, so it was impossible to filter virus 100%.

Too many options, the first choice is purification function

It is understood that the current market in the sale of a wide range of air purifier brands, complex types. HEPA purification technology, RBD plasma filter, ufco platinum decomposition formaldehyde module… These unfamiliar technical terms let consumers see flowers in the mist. How to choose the right air purifier? Industry insiders suggest that consumers focus on three key points: brand, price and sterilization effect. Brand strength directly determines the later use guarantee of products, so the choice should be particularly cautious“ It’s better to choose qualified enterprises with regular channels and choose energy-saving and environmental protection products with filtering PM2.5, activated carbon, ultraviolet sterilization function and low noise. ” Xiaozhuang, sales manager of a household appliance brand, suggests that you can look at the internal activated carbon filter screen when purchasing. The heavier the weight and the higher the density of the filter screen, the better the adsorption effect and the longer the service life.

Is small air purifier useful?

Air purifier has become a kind of household electrical appliances that people must buy. But in many cases, some families have small indoor area. When choosing air purifier, he will not choose the air purifier with large purification area. He feels that he can’t use it, so he will consider the smaller purifier, but he is afraid that after choosing the smaller air purifier, there will be no effect.

1. Whether it is a small or mini air cleaner or a conventional air purifier, it has its basic functions, that is to remove the particulate pollutants in the air, and the common particulate pollutants are smoke, pollen, and sensitive source.
2. The air purifier using the principle of negative ion releases a large number of negative ions when working. Negative ions have good characteristics of adsorbing particle pollutants, while the general particulate pollutants are attached with various virus bacteria, and the negative ions adsorb the particulate pollutants to make them agglomerate into larger particles, and then settle down. Meanwhile, the strong oxidation of negative ions destroys bacterial viruses to achieve sterilization The function of detoxification and air purification.
3. Generally, the particle pollutants in the air will be charged. The air purifier using the negative ion principle releases a large number of negative ions when working. These negative ions are neutralized with the charged particles in the air to make their charges disappear. Therefore, the air purifier using the negative ion principle has the effect of eliminating static electricity.

In fact, the technology of air purification adopted by small air purifiers is similar to that of conventional air purifiers. Small air purifiers are the reduced version of large air purifiers, which can purify air. Only small air purifiers, the speed of purified air is not faster than that of large air purifiers, and its applicable area will be less than that of large ones.

How to Choose

  1. Choose the right purchase channel

When buying an air purifier, it is recommended to buy it from formal channels such as large shopping malls, electrical appliances stores, brand specialty stores, and mainstream e-commerce websites as much as possible.

As of 2013, the brand, function, performance, appearance design and price of air purifiers are very different, which is dazzling. Consumers are advised to choose products according to their actual needs, not that the more functions the better.

For example, for consumers who need to protect against PM2.5, it is recommended to choose an air purifier with outstanding PM2.5 purification ability. Newly decorated homes can focus on air purifiers with outstanding ability to remove formaldehyde and toluene.

  1. Filtration technology

The particulate pollutant filtration technology is mainly HEPA filters. The quality of HEPA filters is uneven. Although some small brands of filters have higher filtration efficiency, they have high resistance, low energy efficiency ratio, and are easy to block and have a short lifespan. , It is generally recommended to choose a deep dust-holding HEPA filter with electrostatic electret. The electrostatic electret technology makes the non-woven fibers have positive and negative charges, which can effectively capture particles in the air. Many HEPA filters are known to have electrostatic electret technology. However, due to technical reasons, the electret charge of many filters will decay quickly in a relatively short period of time, resulting in a decrease in filtration efficiency.

You can choose the HEPA filter such as 3M electrostatic electret on the market, and use the same electrostatic electret technology as the 3M mask to permanently ensure that the electret efficiency is not attenuated.

  1. Pay attention to the applicable area or particulate clean air volume (CADR)

The purification capacity of the air purifier is mainly determined by the applicable area and the amount of particulate clean air (CADR: the rate of clean air provided). The relationship between the two is: applicable area = CADR×0.1. The purification capacity of other pollutants should be combined with the applicable area.

  1. Energy efficiency ratio and energy efficiency rating

Air purifiers are usually used continuously for a long time. Energy efficiency ratio, as an important indicator to measure the purification capacity and power consumption of air purifiers, is worthy of everyone’s attention. The higher the energy efficiency ratio and energy efficiency level, the more energy-efficient the air purifier is and the lower the cost of use.

  1. Ozone release

As a strong oxidant, ozone has a certain purification ability, but it is harmful to the human body. The country has mandatory safety requirements for the amount of ozone released by air purifiers, which is limited to ≤5×10-6% (ozone has a fishy smell).

 

Selection strategy

First of all, the use environment and the effect to be achieved should be considered. General indoor air pollution: 1. Allergens such as dust, viruses, bacteria, molds and mites; 2. Inhalable organic volatile gases, such as formaldehyde, benzene, ammonia, etc.; 3. Radon gas released from stratum and building decoration materials Radioactive pollution caused by its progeny. Therefore, when selecting air purification products, their functions and effects should be considered comprehensively.

Secondly, the purification capacity of the air purifier should be considered. If the room is large, you should choose an air purifier with a larger air volume per unit of time. Generally speaking, a larger purifier has a stronger purification capacity. For example, a room of 30 square meters should choose an air purifier of 120 cubic meters per hour. When purchasing, you can refer to the introduction in the catalog or manual to choose.

Third, the service life of the purifier should be considered, and whether it is easy to maintain. For some products, because the purifier adopts the principle of filtration, adsorption, and catalysis, as the use time increases, the inner filter tends to become saturated with the air purifier, and the purification capacity of the equipment decreases. It is necessary to clean and replace the filter and the filter. The purifying filter with regenerative capacity (including high-efficiency catalytic activated carbon) should be selected to extend the service life; some electrostatic products do not need to replace related modules, as long as they are cleaned regularly.

Fourth, the match between the layout of the room and the purifier should be considered comprehensively. The design of the inlet and outlet wind of the air purifier has a 360-degree ring design and a one-way design.

 

Buying skills

  1. Filter material. Good filter materials (such as HEPA high-density filter materials) can absorb pollutants above 0.3 microns as high as 99.9%.
  2. Purification efficiency. If the room is large, you should choose an air purifier with a large unit air volume. For example, for a room of 15 square meters, you should choose an air purifier with a unit air volume of 120 cubic meters per hour.
  3. Service life. As the purifying filter becomes saturated, the adsorption capacity of the purifier will decrease, so consumers should choose a purifying filter with regeneration function to extend its life.
  4. Room layout. The air inlet and outlet of the air purifier have a 360-degree circular design, and there are also unidirectional air inlets and outlets. If the product is not restricted by the room layout, you can choose a product with a circular air inlet and outlet design.
  5. Demand. Choose an air purifier according to the types of pollutants that need to be purified. HEPA has a strong purification function for smoke, suspended particles, bacteria, and viruses. Catalytic activated carbon has a better purification effect on odors and harmful gases.
  6. After-sales service. After the purification filter fails, it needs to be replaced by the manufacturer, so you should choose products from enterprises with perfect after-sales service.
