PConline tips come winter, buy small home appliances will be far behind? Into the winter, I believe that many users are like Xiao Bian, will choose to buy some home appliances for the home, such as air purifiers, heaters, humidifiers and so on. Next, Xiao Bian will list some of the myriad misunderstandings that many friends have in the process of purchasing small household appliances. Do not believe that you should look down!
Sweeping machine to buy errors
Whoever is cheaper I will choose
Including Xiaobian, everyone wants to get the best product at the lowest price. However, the sky can not really lose the pie, or quickly wake up!
E-commerce sweeper prices
In today's home appliance market, domestic businessmen are engaged in a "civil war" on prices. As a result, the prices of many commodities have also been declining. But we must make it clear that as a commodity, it must realize its value through a form of expression. Perhaps price is one of them. As the saying goes, "Good goods are not cheap, and cheap goods are not good." In the face of a dazzling array of sweeping machines, we cannot blindly select the cheapest ones. We can only pick the most rational price products.
Sweepers are not as thin as possible
Sweepers are not as thin as possible
Thin, thin, thinner, some friends think that the thinner the better the sweeping machine, some friends think that the thinner the sweeper, the more you can clean to the place under the bed, under the sofa and other places usually cleaned, then Sweeper is not the thinner the better it, in general, the thickness of the sweeper can reach 90mm can be considered ultra-thin, but some manufacturers in order to take into account the needs of some consumers to reach 60mm, of course, ultra-thin design Can be better to clean the narrow space will not be cardholders, but if the sweeper is too thin may cause a small battery capacity, short working hours, some large garbage can not be better cleaned and other issues, all have two sides, I hope friends According to the actual situation of their own homes.
Parameters and attachments are all floating clouds
Many consumers often pay attention to the price when they buy a sweeper. They feel that the parameters and accessories of the sweeper are not important.
Attachments and parameters are important
In fact, the various parameters of the qualified smart sweeper packaging must be complete, there should be instructions, warranty, certification, etc. If the machine is missing any one, please consumers carefully purchase. Consumers are advised to check whether the product has a 3C logo. This is a nationally recognized quality symbol. If the product does not have this symbol, it is not recommended.
After sales service is not important
Lack of after-sales service can be a headache
In the process of purchasing sweeping robots, some consumers only pay attention to their sweeping ability, endurance ability and other factors, and it is easy to ignore their after-sales services. In fact, as a high-tech product, smart sweeping robots are becoming more and more intelligent. Therefore, when it fails, after-sales service is also very important. In the event of a failure, watching sweeping robots without after-sales service, I believe many users will be very crazy.
Air purifier to buy errors
Ventilation through the windows, air conditioning inside the car can remove pollutants in the car, do not need air purifier?
Do you not need an air purifier for window ventilation?
The China Indoor Decoration Association Indoor Air Monitoring Center once tested 200 vehicles. The results were based on indoor air quality standards. It was found that nearly 90% of cars had problems with excessive levels of formaldehyde or benzene in the car's air, and most of the vehicles exceeded the standard. ~6 times more. The volatilization of formaldehyde lasted for decades. It was impossible to achieve the purification effect by relying on window ventilation and air conditioning in the vehicle. Moreover, in the case of severely polluted weather and no way to open windows, only air purifiers can be used to remove pollutants. Therefore, from a health point of view, as in the car and at home, it is also necessary to prepare a professional car air purifier.
Can a purifier remove PM2.5?
The original intention of many consumers to buy air purifiers is to remove PM 2.5, but, in addition to PM 2.5, formaldehyde, benzene series, pathogens, PM 0.3 and other pollutants are also extremely harmful, for example, the diameter in the atmosphere ≤ 0.3 The micron particulate matter (PM 0.3), containing various harmful substances, can enter the blood through the alveolar wall and is one of the root causes of lung cancer, liver cancer, and lymphoma. Therefore, these pollutants are also within our consideration.
Can remove PM 2.5 is no longer the only standard
In addition, formaldehyde is a colorless gas with a strong irritating odor that is recognized by the World Health Organization as a carcinogen and has a volatilization cycle of several decades. In addition, germs are microscopic organisms that can cause diseases in the body. They are tiny in size and enter the human body through a variety of ways. They multiply in the human body and infect the human body. Therefore, when choosing an air purifier, it is not enough to consider whether it is possible to remove PM 2.5.
With HEPA filter, is a good air purifier?
The HEPA network has strict grade points, and different levels of HEPA filter effects are very different. The higher the HEPA network level, the smaller the particle diameter that can be filtered and the better the filtering effect.
HEPA filter
At present, ordinary air purifiers on the market use H10H9-class HEPA networks. Some high-end air purifier brands use H12-level HEPA networks, and a few high-end air purifiers use H13-level HEPA networks. The PM 2.5 once-only purification efficiency reaches 99.9% or more, and the one-time purification efficiency of the smaller 0.3μm particles can reach 99.97%, and the filtering effect is excellent. Therefore, using the HEPA network technology can not be said to be a good air purifier, and it depends on what level of HEPA network is used.
Humidifying air purifiers can both purify and humidify.
Humidifier air purifier
Scientific research shows that particulate contaminants in the air after humidification are more likely to enter the lungs and the blood system. At the same time, the humidified sink is prone to bacterial growth. Bacteria enter the air with humidified water vapor and is easily inhaled by the body. Because of this, many professional air purifier brands do not have a humidifying function, and some businesses are actually unscientific in order to increase product selling points and add humidifying functions to air purifiers. Some consumers in the "spend a penny, buy two functions" mentality, it is easy to fall into this misunderstanding. So, if you really need to, you should buy a separate professional air purifier and humidifier.
Humidifier buy error
The humidity is not as high as possible
A humid environment will make people feel comfortable, but the humidity of the air is not as high as possible. Experts pointed out that the human body feels more comfortable humidity is 40% -60%, air humidity is 55%, the bacteria difficult to spread; if the air humidity exceeds 65%, people will feel chest tightness, difficulty breathing; if more than 90%, respiratory system And mucous membranes will produce discomfort, but it will easily lead to respiratory diseases such as asthma. If the air humidity is too high, it will be particularly unfavorable to the elderly and it will induce the elderly to suffer from influenza, asthma, bronchitis and other diseases.
Isn't the air humidity higher?
Another group of people is babies. Because the baby's skin is delicate, the moist environment will prevent the skin from chapped and painful due to dryness. However, if the air humidity is too high, the respiratory system and mucous membranes will be uncomfortable and the immunity will be reduced, which will induce children suffering from influenza, asthma, bronchitis and other diseases. If not regularly cleaned, molds and other microorganisms in the humidifier will enter the air with the mist, and then enter the human respiratory tract, and are prone to "humidified pneumonia."
What kind of water will the humidifier do?
Can't directly add tap water to the humidifier?
Many people use humidifiers, but they do not know that they cannot directly add tap water to the humidifier. Because tap water contains many kinds of minerals, it will cause damage to the evaporator of the humidifier, and the water and alkali it contains will also affect its service life. Chlorine atoms and micro-organisms in tap water may be contaminated with water mist blown into the air. If the tap water has a high hardness, the water mist sprayed from the humidifier will contain calcium and magnesium ions, resulting in white powder and contaminating the indoor air. When the sales staff recommends products, they may not take the initiative to explain the problem to you. As a result, after the user purchases the humidifier to go home, tap water is always used for convenience.
Carefully select, do not let the humidifier become a "bacterial device"
　　 There are many kinds of humidifiers on the market. High-quality humidifiers and healthy and environmentally friendly production materials not only give consumers the humidity needed for air, but also can purify the air and effectively filter harmful dust particles in the air to achieve humidification. The effect of purifying the air is heavy.
Choose humidifier products produced by genuine manufacturers
　　 In addition to the humidifier products produced by genuine manufacturers, there are also many humidifier products available on the market, which simply attract consumers at low prices. In order to reduce the cost and use inferior plastics, it is easy to cause the volatilization of harmful substances during the use process, causing hidden dangers to health. In addition, poor humidifiers generate large noise during operation, and severe sleep and rest. We hope that when consumers purchase humidifiers, they must also keep their eyes open and choose powerful brands with quality assurance.
Electric heating machine to buy errors
Great power heating effect is good
If you are blindly pursuing high power and think that the power is great and the heating effect is better, then you are wrong. Not suitable for their own high-power appliances, not only cause waste, but also easily cause tripping and heaters burned. So you can't just look at power, you should choose the most appropriate one.
Propaganda doesn't have to fly
Do not blindly listen to propaganda
With the increasing number of heater products, many heater manufacturers boast about the health care function of the product. Technologies such as air filtration and negative ion purification air are widely used in PTC ceramic heaters, and some electric heaters have also added humidifiers. In fact, heating appliances is not a medical device. Some things have no practical effect on us.
Cheap is a good product?
Cheap is good stuff?
As the saying goes, there are no good goods for cheap, but many consumers use low prices as the main indicator of purchase because of their own economic strength or other aspects. However, many people do not know that low-priced heaters are likely to use inferior zero. part. Taking the oil radiator heater as an example, according to industry insiders, individual manufacturers will change the internal connection to ordinary wire, shell steel plate using ordinary steel, do not install overheating protection devices, reduce heating film, etc., this undoubtedly buried the family security Hidden danger.
Editor's Note: Full understanding of the misunderstandings of small appliances can help us to purchase the right products. I hope that my friends can purchase the small household electrical appliances in the process, can polish their eyes, buy their own truly suitable products, our aim is: do not buy regret goods!
