I must know what to buy a purifier

文章出處:九言科技 人氣:發表時間:2019-03
In recent years, smog in winter has been frequent, and there are a lot of harmful substances such as sulfur dioxide, nitrogen oxides and heavy metals in the smog, which is extremely harmful to human health, especially for the elderly and children who have poor resilience. Words. At the same time, indoor air pollution problems such as interior decoration and cooking have existed for a long time, and many households have adopted air purifiers as a standard for quality life. But just buy an air purifier just fine? In fact, many consumers have different levels of misunderstanding in the use of air purifiers, and some misunderstandings may even lead to secondary pollution. Let's talk to everyone about the misunderstandings of air purifiers.
Myth 1: No matter how big the house is, one is enough.
Due to the lack of understanding of the air purifier, local people feel that it is enough to have a small air purifier in the house. In fact, the air purifier has a corresponding applicable area, which is similar to the air conditioner, except that the air conditioner is different in size.
The local air purifier on the market has a clear indication of the applicable area. If not marked, the cleaned area of ??the air purifier can also be stopped by the CADR value (clean air volume) of the product: the applicable area = CADR* (0.07) ~0.12), the corresponding CADR value can be calculated for the practical purification area, thereby assisting consumers in selecting the air purifier product. In general, large-sized rooms can be thought of as equipped with the corresponding air purifiers.
Myth 2: Air purifier is placed against the wall
After many consumers have purchased an air purifier, they will choose to place the air purifier against the wall due to planning or not understanding the detailed principles at home. In fact, the air purifier needs different positions depending on the air inlet of the air outlet.
However, the position of the air purifier is still required to adhere to the wall at a certain interval, so that the air inlet and the air outlet can be better maintained by the air flow and the sensor. As for ordinary households, the lower central accumulation of viruses or particles is more, the machine can achieve the best filtration effect, and leave a certain space around to ensure air circulation, which is conducive to improving air purification efficiency.
Misunderstanding 3: Put the humidifier next to the purifier
After many friends have purchased an air purifier at home, they will also purchase a humidifier to prevent the winter room from being too boring. When using the air purifier, turn on the humidifier at the same time. In fact, it has been found that if the humidifier is placed next to the air purifier, the indicator light of the purifier will be alarmed, and the air quality index will rise rapidly. It seems that the two will interfere with each other.
In fact, this is because the water in the humidifier is not pure water, but tap water. Because tap water contains more minerals and impurities, chlorine molecules and microorganisms in the water may be blown into the air with the mist sprayed from the humidifier. , constitute a source of pollution. If the hardness of tap water is high, the water mist may have white powder, which will also pollute the indoor air. Therefore, if you want to turn on the humidifier and the air purifier at the same time, you must leave enough space.
Myth 4: The air purifier is close to people.
When the air purifier is working, due to its working principle, the harmful gases around the air purifier are actually much more. Therefore, do not place it in the center too close to people, but also should be properly raised to prevent children from coming into contact.
Moreover, an air purifier such as an electrostatic adsorption type can cause pollutants in the air to be adsorbed on the electrode plate during operation. However, if the design is not reasonable enough, a small amount of ozone will be released, and exceeding a certain amount will stimulate the respiratory system. When using this air purifier, it is best not to stay in the room, and to close it after entering the house. Because ozone can be quickly recovered in space, it will not stay for a long time.
Misunderstanding 5: Do not change the filter for a long time
Many people often ignore the life cycle of the air purifier filter and use cleaning in the process of using the air purifier. Since the filter has a certain degree of saturation, during the operation of the air purifier, the purification function will gradually drop as the adsorbate increases. Moreover, after the filter is saturated, the particles adsorbed on the filter net will become a hotbed of virus pathogens, which will multiply and breed bacteria. If it does not stop changing for a long time, continuing to use will not only purify the effect, but will release harmful substances. "Pollution source", forming secondary pollution.
However, many brands of air purifiers on the market now have intelligent tips to change the filter screen and clean the prompt function, and must be changed in time when the demand changes. However, the washable filter like the primary filter is still recommended to be cleaned regularly. After all, the purification effect will be worse after a large amount of adsorption, and the life of the rear filter will be reduced at a certain level.
Misunderstanding 6: Haze genius needs to use air purifier
The hot sale of air purifiers is mainly caused by the continuous smog weather, but it is not as long as the smog is pollution. In many real situations, indoor air pollution is far more terrible than smog. As early as 2011, the World Health Organization pointed out that indoor air used to be 5-10 times higher than outdoor air pollution. For example, bacteria, viruses, pollen, dust, odor, bacteria, chemical gases, etc. suspended in the air will have an adverse effect on the human body, and even severely affect the health of the human body. In particular, new homes that have just been renovated, and those who are vulnerable to the elderly, children, and other vulnerable people are even more harmful.
Of course, if the outdoor air is good, it is still recommended that the room be ventilated and ventilated, and insist on a certain humidity so that the novel air can move indoors. Sometimes this effect is more effective than opening an air purifier all year round.
Myth 7: No smell in the room means the air is very clean.
The indoor air specification is a comprehensive trade-off indicator including the content of inhalable particulate matter, harmful gases, odors and bacterial viruses. It is not reasonable to determine the air quality by odor alone. In addition to the large particles and odors that are easily exposed, formaldehyde, benzene, radioactive cesium and other undesirable gases are colorless and odorless, as long as they are detected by the air purifier, these bad gas collars will form a pole. Great damage.
Misunderstanding 8: Purify for a while
Local consumers will feel that it is very expensive to open the air purifier for a long time. In order to save electricity or to clean up the effect for a certain period of time, it will be turned off after a certain period of work. In practice, the air purifier itself is not high in power consumption. It belongs to power-saving small household appliances. At present, air purifiers with better quality have intelligent forms and power-saving disposal mechanisms. When the air is detected, the air purifier will start running at a low speed. If you sit on the side and start smoking, it will automatically run quickly, and then resume the smart form after reaching the standard.
And the most important thing is that after the air reaches the standard, the PM2.5 concentration in the indoor space will gradually increase under the condition that the purifier stops working. During the process, PM2.5 will continue to enter through even closed doors and windows. Therefore, it is good to continue to open the purifying effect under normal conditions, especially when the haze is serious.
  to sum up:
In the current smog in the smog, the use of air purifiers has long been a necessary measure to effectively protect the family's breathing and well-being. However, as long as we prevent misunderstandings and scientific use of air purifiers, we can improve indoor air quality more quickly and effectively, and truly enjoy the comfort of the air.
