Seven Misunderstandings about Air Purifiers Improper use can cause secondary pollution
Winter smog frequently erupts, 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 with poor resistance. 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 as long as you buy an air purifier, would you? In fact, many consumers have different levels of misunderstanding in the use of air purifiers, and some misunderstandings may even bring secondary pollution. Let’s talk to you about the misunderstandings of air purifiers.
Misunderstanding one
No matter how big the house is, one is enough.
Due to the lack of understanding of the air purifier, some people think 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 for different sizes of rooms.
Some air purifiers on the market have clearly marked applicable areas. If not marked, the purifying area of the air purifier can also be calculated from the CADR value (clean air volume) of the product: applicable area = CADR* (0.07) ~0.12), the corresponding CADR value can be calculated for the actual purification area, and then the consumer can select the air purifier product. In general, large-sized rooms may be considered to have a corresponding air purifier in the number of rooms.
Misunderstanding two
Put a humidifier next to the purifier
After many friends have purchased an air purifier at home, they will also purchase a humidifier to avoid the winter room being too dry. 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 added to 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. Form a source of pollution. If the tap water has a high hardness, the water mist may have white powder, which may also pollute the indoor air. Therefore, it is recommended that if you need to turn on the humidifier and air purifier at the same time, be sure to leave enough distance.
Misunderstanding three
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 more. Therefore, do not place it too close to people, but also should be properly raised to avoid contact with children.
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 more than 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 restored in space and will not remain for a long time.
Misunderstanding four
Do not change the filter for a long time
Many people in the process of using air purifiers often ignore the life cycle of the air purifier filter and use cleaning. Since the filter has a certain degree of saturation, during the operation of the air purifier, the purification function will gradually decrease as the adsorbate increases. Moreover, after the filter is saturated, the particles adsorbed on the filter will become a hotbed of virus pathogens, which will multiply and breed bacteria. If it is not replaced for a long time, it will not only purify the effect but will release harmful substances. “Pollution source”, causing secondary pollution.
However, many brands of air purifiers on the market now have smart reminders to replace the filter screen and clean the reminder function, and must be replaced in time when it needs to be replaced. However, the cleanable filter screen like the primary filter screen is recommended to be cleaned regularly. After all, the purification effect will be worse after a large amount of adsorbent, and the life of the rear filter net will be reduced to some extent.
Misunderstanding five
Haze genius needs to use air purifier
The hot sale of air purifiers is mainly caused by the continuous haze weather, but not only the haze is pollution. In fact, in many cases, indoor air pollution is far more terrible than smog. As early as 2011, the World Health Organization pointed out that indoor air is 5-10 times higher than outdoor air pollution. For example, bacteria, viruses, pollen, dust, odor, bacteria, chemical gases, etc. suspended in the air can cause adverse effects on the human body and even seriously threaten human health. In particular, new homes that have just been renovated are even more harmful to vulnerable people such as the elderly and children with poor resistance.
Of course, if the outdoor air is good, it is recommended that the room be ventilated and ventilated, and maintain a certain humidity so that fresh air can flow indoors. Sometimes this effect is more effective than opening an air purifier all year round.
Misunderstanding six
No smell in the room means the air is very clean.
The indoor air standard is a comprehensive measure of the content of inhalable particulate matter, harmful gases, odors and bacterial viruses. It is unreasonable to determine the air quality by odor alone. In addition to the large particles and odors that are easily felt on the surface, formaldehyde, benzene, radioactive cesium and other undesirable gases are colorless and odorless, and will only be revealed by the detection of air purifiers. These bad gases will cause great damage to the body. hurt.
Misunderstanding seven
Purify for a while
Some consumers will feel that it is very expensive to open the air purifier for a long time. In order to save electricity or think that the purification can achieve the effect for a certain period of time, it will be turned off after a certain period of work. In fact, the air purifier itself does not consume much electricity. It belongs to power-saving small household appliances. At present, the air purifiers with good quality have intelligent mode and power-saving processing mechanism. When the air is detected, the air purifier will start running at a low speed. If you start to smoke while sitting on the side, it will automatically run quickly, and then resume the smart mode after reaching the standard.
Moreover, the most important thing is that the PM2.5 concentration in the indoor space will gradually increase after the air is up to standard, and the PM2.5 will continue to enter through even closed doors and windows. Therefore, it is usually good to continue to purify the effect, 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 health of the family. However, only by avoiding misunderstandings and scientific use of air purifiers can we improve indoor air quality more quickly and effectively, and truly enjoy healthy air.
