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 calculate the purification area of air purifier

If you want to know the purification area of an air purifier, you need to know the CADR value of the purifier first. Then what is the CADR value?
CADR is the acronym of clean air delivery rate. It can be simply understood as the total amount of clean air output by air purifier after removing solid particles per unit time. It is an important index to evaluate the purification performance of an air purifier.
The internationally recognized “CADR value” is the result of testing the air purifier under certain testing conditions by AHAM. Generally speaking, the larger the power of the detected air purifier is, the higher the output value of clean air is, and the larger the applicable area is.

According to international practice, a qualified air purifier can purify indoor air five times per hour. So, how can we judge the room area that can be purified by the CADR  value of an air purifier?
In fact, we can easily get the result through a formula【 Applicable area s (M2) = 12F / 60H] in the formula, s on the left represents the area to be calculated, f on the right is the maximum air output of the air purifier, i.e. CADR value, and H is the floor height of the room, generally calculated as 2.8m. According to the international standard, the indoor air should be purified five times in an hour, that is, every 12 minutes, so the numerator and denominator are multiplied by 12 and 60.

be careful:
However, the applicable area of the air purifier is only a reference data. Due to the influence of the air exchange volume in the room, the floor height of the house and the number of furniture placed in the room, the specific value of the applicable area of the house is not the same, and the so-called applicable area is only a reference value.
In addition, many air purifiers also have the function of removing formaldehyde, and the CADR value of purifying formaldehyde is generally weaker than that of purifying particulate matter. So in the purchase of air purifier must be consistent with their actual needs.

In summer, formaldehyde air purifier is more needed

In general, users are used to decorating rooms in spring, and “let the wind” exhaust poison for newly decorated rooms in summer. After the new house is decorated, it can be moved in 3-6 months, but this does not mean that the pollutants are completely dispersed.
Some experiments show that the formaldehyde emitted from wooden furniture and floor will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times when the indoor temperature rises by 1 ℃. In summer, indoor and outdoor are in a high temperature and humid environment, which will accelerate the release of formaldehyde in furniture and other decoration materials. Especially in summer, indoor and outdoor are in a relatively high temperature and humid environment, which will accelerate the release of formaldehyde. Most users will smell pungent smell in the newly decorated rooms. Therefore, for the new house decoration time is short, the new home bought a few pieces of furniture, the old house for local decoration, especially in summer should pay attention to formaldehyde.
