Is it reliable to buy air purifiers online?

　　Society is progressing, and everyone's living environment is also improving, but our indoor air quality is regressing. why is that? The reason is that in a large number of artificial composite materials are used for home improvement materials, furniture and interior items. If these do not meet the qualified requirements, volatile organic compounds such as formaldehyde and toluene will be released, thus endangering human health. Many people choose to use air purifiers, and online shopping is a shopping mode that everyone prefers. How to judge whether buying an air purifier online is reliable?

　　Online shopping has these advantages:

　　1. The Internet has greatly facilitated our shopping mode. We can search for many types of air purifiers on the Internet, which is convenient for everyone to compare and choose. In physical stores, the products are relatively simple, and the choice for everyone is relatively poor.

　　2. From January 1 this year, my country's first air purifier China environmental labeling standard has come into effect. You can refer to the standard to choose and do whatever you want. Going to a physical store may be fooled by the sales staff, which will ultimately outweigh the gains.

　　3. Why is online shopping so popular? In addition to convenience, it is cheaper. The same product online is definitely cheaper than the physical store. Because physical stores are not like online stores, they need to pay rent on a regular basis, which increases the cost.

　　So online shopping has so many advantages, why do some people still dislike online shopping? There must still be a deficiency.

　　Disadvantages of online shopping:

　　1. After all, online products are virtual, you can only watch the photos above, but you don’t know what the actual product is, and it requires a certain delivery time, which is not as convenient as a physical store.

　　2. It is true that online shopping products are cheaper than physical stores, but there are also many fake and inferior products mixed in, and it may not be as convenient as physical stores in terms of after-sales, and it needs to be communicated through information.

　　3. The specific performance is unknown, and the test can only be carried out after the arrival of the goods. If it is not suitable, it needs to be returned.

　　After knowing these advantages and disadvantages, we are more handy when choosing an air purifier.

　　Online shopping precautions:

　　1. First of all, we need to go to the enterprises that have their own brands to understand and analyze their products. Because of the problems with the products of these enterprises, it will become easier for us to safeguard the interests of consumers.

　　2. When buying goods on Taobao and Tmall, a common problem that everyone has is to look at the product and the sales volume. This also leads to the blindness of shopping. Because what you see is not necessarily the voice of consumers. Only after you really understand its products, you can finally choose the one that is right for you.

　　3. According to the method of "three highs and one low", that is, clean air volume, high cumulative purification volume, high purification energy efficiency, and low noise.
