Friends of the post-80s and post-90s all like online shopping, especially house girls. There are more than 4 megabytes of broadband, so you can not drink water or eat on the same day. Our parents want to buy things and like to do it themselves. They are dragging a ticket in their hands. If they take a fancy to it, try it first, experience it for a while, and then pay for it. In their words, rest assured and be practical; If you let them buy things online, it's called relying on the manager. Today, in the 2 1 century, the development of e-commerce is quite mature, and online shopping is gradually recognized by everyone. Online trading depends on everyone's integrity. No matter how big the forest is, there are all kinds of birds. There will always be some black sheep, selling fakes under the banner of authenticity, and sometimes it is impossible to prevent. Today, taking the air purifier as an example, I will share some purchasing tips with you.
On the Internet, when you see the manufacturer of the air purifier say: in addition to formaldehyde, sterilization is 99.999%, patent purification and dust removal ... We should ask more questions about this "machine" that can cure all diseases, and don't be confused by gorgeous language and beautiful pictures.
1. What is the principle of benzene removal in in addition to formaldehyde? Like ordinary air purifiers, what is the principle of installing medium and high efficiency and activated carbon filters? Or use high-voltage electric field adsorption technology? What is the purification rate and the deviation between the laboratory and the actual value? Is there a third-party test report?
Second, sterilization and disinfection reached 99.99%. Is it all germs or some germs? How long does it take to reach this value, and how much is the deviation between the laboratory and the actual environment? The most important point: is there a disinfection and hygiene production license, and can you provide the product safety evaluation and sterilization test report of the authoritative organization?
Third, the so-called patented technology is a part, not to mention a screw! What is the key function of this product and how to prove its efficacy?
Fourth, the price of products is really chaotic now. The air purifier has only a few filters, and the price has soared to more than 10000. Our sterilization+purification in Wei Yi is only over 8K, which is a little unbearable. Friends must pay attention to high-priced products, or you will be miserable if you maintain several thousand yuan at a time after buying them. Anyway, before you buy it, the salesman said, OK! Both! No problem! I can't help you once the money is transferred.
A few days ago, a customer from this province asked us to consult Wei Yi cabinet air disinfection machine, and I applied for 6K, in addition to formaldehyde, which was sterile, environmentally friendly and beautiful. People ungrateful to buy several air purifiers outside the province, the price 1.6 million, just a few filters, millet output is much better than them, it is still a plastic shell, I don't know what to say. So back to the theme of our chapter: Is it reliable to buy things online? If you meet someone who really does business like me, I promise to explain them one by one; If you meet a family that can cure all diseases and three "good" are not enough, you should be more careful.
