Nowadays, air pollution makes people miserable. Especially in the winter in the north, it is very difficult to describe the seriousness of air pollution in language. It also brings a lot of troubles to people's lives. In fact, everyone has long known that haze is very harmful to our body. Big. In the winter, the respiratory departments of large and small hospitals in the north are always “overcrowdedâ€. "Only a small percentage of patients with respiratory diseases are due to their own physical problems, and most of the patients are due to bad weather," said a frontline medical worker.
We can't get rid of the big environmental pollution, but it is still very easy to solve the problem of air pollution in the small environment. Some surveys show that people spend 60% of their time at home, so the problem of pollution in the small environment of the family has been solved. Our body will suffer less harm.
The most effective way to change the air pollution problem in the small-scale environment of the family is to use an air purifier. Then the question is, what kind of air purifiers, brands and models are on the market? Which one should choose? Many people choose air. The purifier will be very entangled. First, the price ranges from a few hundred to over 10,000, and the price range is very large. The second brand has never heard of it or is a big brand of the international first-line brand; the third product size is from a few The pound weighs hundreds of kilograms.
In fact, the choice of air purifier is not so difficult, the price is too expensive, it may not be better, tens of thousands of air purifiers are actually unnecessary, the effect may not be better than the reliable machine of thousands of dollars, the brand It is best to believe in those big brands that are well-known, but don't be superstitious about what is called “big nameâ€. In the end, it is the size. In fact, the size of the product should be determined according to the actual use area. Each air purifier product has a CADR value. Dividing the CADR value by 0.07 - 0.12 is the applicable area of ​​this machine.
Recently, the Haier Net Magic Air Purifier (KJ420F-HMA) I bought is actually a very good product. The CADR value of 420m3/h can be applied to the room of 35-60 plane, and the purification speed is also very fast. . Haier Net Magic Cube air purifier has six layers of filters, which can not only filter out particulate matter but also filter out pollutants such as formaldehyde and bacteria. This purifier is also equipped with laser air quality detector, indoor PM2.5, formaldehyde, The temperature and humidity situation is clear at a glance... This Haier net enjoys the Rubik's Cube Air Purifier and there are many points that are very comfortable to use. Here is my experience evaluation of Haier's net magic air purifier (KJ420F-HMA).
Product packaging
Received the product (I bought the machine through the e-commerce, it is still quite a surprise, and the logistics is also very strong, the first day of the order will arrive the next day), know that the price of paperboard is not cheap, this machine The outer packaging still uses a high-grade paperboard. On the outer packaging, I still had an unexpected discovery - Beijing Zero Micro Technology Co., Ltd., I started to wonder if I suddenly realized that Beijing Zero Micro Technology Co., Ltd. had many authoritative media reports and gave it a high degree.
