Domestic air pollution is getting worse and worse, and the air purifier has gradually become a daily necessities kept by many people from the original rarity. Users who have consistently distrusted domestically produced goods often tend to choose foreign brands when they purchase, and some are far away from looking for friends to purchase air purifiers from abroad, and think that foreign things are better than domestic ones. However, Xiao Bian wants to say here that there is nothing wrong with choosing foreign products in China. It is not so rational to spend manpower and resources from the foreign purifiers.
Wide difference in air quality standards at home and abroad
Most people will choose to come back from Japan or Europe 扛 air purifiers, thinking that European goods or Japanese goods are better than domestic goods. From the perspective of product quality, I dare not say that domestically produced goods are better than European goods and Japanese goods, but from the perspective of controlling domestic air quality, it is definitely a domestic brand that is better than foreign brands.
The air quality varies from country to country and the level of pollution is different. Generally speaking, because the foreign air is generally better than the domestic one, the purification ability of foreign air purifiers is relatively weaker. There is no problem with the use of such purification power in foreign countries. But it is not enough in China. In addition, most air purifiers need to replace the filter element during use. It is not always possible to buy each type in the country, so the sustainability of later use will also be affected. Therefore, it is recommended to buy an air purifier not to blindly believe in foreign goods, and should make more pragmatic choices according to the actual situation.
The necessary structural design determines the purification capacity of the air purifier
Some time ago, there were some people who were keen on purchasing a German brand air purifier. It is said to be able to remove formaldehyde and PM2.5, and the effect is very good. However, Xiaobian carefully studied and found that the brand's air purifier consists of, in simple words, the water wheel + water tank. The general principle is that the louver water wheel continuously rotates the pollutants in the air, and is immersed in the water by rotation, thereby completing the purification process. The user does not need to change the net, it only takes about 10 days to replace the water in the water tank.
Here, Xiaobian wants to remind everyone that at present, in addition to electrostatic dust collection design, general air purifiers need to rely on HEPA filters to remove PM2.5; in addition to formaldehyde, they need corresponding streamer energy or activated carbon filters or Other decomposition technologies developed specifically for formaldehyde. It is true that water can decompose formaldehyde, but formaldehyde can only be dissolved in living water, and the still standing water does not pose any threat to formaldehyde, let alone PM2.5.
Therefore, such a simple design of the air purifier may be effective in foreign countries with good air quality, but for domestic air pollution with serious pollution, such products can only play a good humidifying effect, and it is impossible to decontaminate. It’s gone.
Therefore, I also recommend that you choose the air purifier to talk about the effect, do not blindly worship Haitao, purchasing, etc. After all, not all imported products are better than local products.
