空气净化器，要选三观正确的纯物理过滤
关于PM2.5检测仪的对比评测还要再等几天，今天还是再聊聊空净。
The comparison and evaluation of PM2.5 detector will wait a few more days.
我们在去年关于如何对比空气净化器的文章中，提到过选择空气净化器最重要的标准，就是“纯物理”。在我们看来，纯物理是必须的保底选项。很多读者留言问blueair，远大等产品如何？抱歉，我们认为对比非纯物理的空净没有意义，因此就不分析了具体产品了。今天来解释一下为什么。
In our article on how to compare air purifiers last year, we mentioned that the most important criterion for selecting air purifiers is "pure physics". In our view, pure physics is a necessary bottom-line option. A lot of readers asked blueair, what about big products? Sorry, we don't think it makes sense to compare the empty space of non-pure physics, so we don't analyze the specific products. Let me explain why.
什么是纯物理空气净化器？
What is a pure physical air purifier?
首先代表化学方向的毕业生们声明，所谓“纯物理”三个字是典型的，助长社会不良风气的学科歧视。所谓非纯物理的空净，用的也还是物理技术。
First, on behalf of the chemistry graduates, the three words "pure physics" are typical and encourage the subject of unhealthy social morality. The so-called non - pure physics is also used as a physical technique.
好吧，俗称纯物理过滤的空净，指的是只用HEPA、活性炭等滤网过滤，清除空气中的PM2.5，甲醛等污染物。
Ok, commonly known as pure physical filtration, it refers to filtering through filters such as HEPA and activated carbon to remove PM2.5, formaldehyde and other pollutants in the air.
而相对非纯物理空净，指的是没有使用滤网，或者在滤网之外使用其他技术，比如最近流行的高压静电集尘技术，此外当然还有日系厂家可能会编造出的各种奇葩名字的技术，如X离子，X因子，XX能等等。
And relatively than purely physical empty net, refers to the screen is not used, or outside of the filter using other techniques, such as the recent popularity of high voltage electrostatic dust collection technology, in addition of course, the Japanese manufacturers could invent all kinds of exotic names of technology, such as ion, X X factor, XX, and so on.
即便是日系净化器中相对靠谱的夏普也患有X离子脑残综合征。
Even the relatively reliable sharpe of Japanese purifiers suffers from the X ion brain injury syndrome.
静电等技术
electrostatics
使用这些技术的主要目的是为了用静电吸附的原理加强颗粒物过滤的效果，或者用负离子/臭氧，或静电等技术杀菌、除味，去除有机污染物等等。
Using these techniques, the main purpose is to use the principle of electrostatic adsorption, enhance the effect of the particle filter, or use/ozone and anion or electrostatic technology such as sterilization, in addition to flavor, removal of organic pollutants and so on.
既然静电吸附技术这么好用，为什么大家不都像什么贝昂、远大一样，搞无耗材纯静电过滤器呢？原因很简单，高压静电类的技术，必然会产生一种比PM2.5还烦人的空气污染物：臭氧。
Since electrostatic adsorption technology works so well, why don't all of us have the same kind of pure electrostatic filter? The reason is simple, the technology of high voltage static electricity, must produce a kind of air pollutant that is more than PM2.5 also: ozone.
和当红的雾霾相比，臭氧危害会被很多人忽视。臭氧是一种强氧化剂，虽然在大气层上面飘着的臭氧层可以帮我们抵御紫外线的伤害。但地面的臭氧污染则会造成我们哮喘、支气管炎、心脏病等心肺疾病，甚至危害生命。
Compared with the red haze, ozone damage is ignored by many people. Ozone is a powerful oxidant, although the ozone layer that floats above the atmosphere can help us resist ultraviolet radiation. But ground-level ozone pollution can cause heart and lung diseases such as asthma, bronchitis, heart disease, and even life.
高压静电技术一定会产生臭氧，只是多少的问题。国家对于电器产生臭氧的浓度有要求，所以一般情况下，这些厂家会在机器中加一层还原层，用来还原机器生成的臭氧，以达到国标，通过检测。
High voltage static technology is sure to produce ozone, just how many problems. Countries have asked to electrical produces ozone concentration, so in general, the manufacturer will add a layer of reduction zone of the machine, used to generate ozone reduction machine, in order to reach national standard, through the test.
贝昂这类高压静电产品据说可以省耗材，但CADR非常低，价格也往往卖得比换十年的滤网还贵。
Such high-voltage electrostatic products are said to be able to save energy, but CADR is very low and prices tend to be more expensive than those for a decade.
满足国标，仍然无法让我们减弱对这个技术的反感。因为世界上不存在永远不会出问题，不会损坏的电器。没有厂家可以保障出厂合格率是绝对的100%，也更不可能保证用户使用1个月，1年，2年，5年之后，绝对没有故障，绝对不会出现臭氧超标的问题。
Meeting the national standard still does not allow us to weaken our aversion to this technology. Because there is no such thing as a problem in the world. No one can guarantee the factory qualified rate is 100% of the absolute, is more impossible to ensure that the user use 1 months, 1 year, 2 years, five years later, there is absolutely no fault, absolutely won't appear the problem of excess ozone.
一般的纯物理净化器，出了问题无非是噪音大点，工作效率低点......但使用静电等技术的产品，就会有造成臭氧超标的风险。那些厂家敢保证10年之后，没有一台机器臭氧超标么？当然不会。那我们凭什么要去赌人品呢？
General pure physical purifier, the problem is no more than noise, work efficiency low... But using technology such as static electricity, there is a risk of excessive ozone. After 10 years, are there any machines that don't have excessive ozone? Of course not. Why should we bet on people?
至于像blueair，日系净化器及类似这种的净化器，使用一定的静电等技术，臭氧生成量相对较少，日常使用不需要担心。但同样无法保证不会有在长时间使用后绝对不会出现类似质量和故障导致的风险。风险或多或少一定存在，那为什么有这么多厂家使用这样的技术呢？
As for blueair, daily purifiers and similar purifiers, the use of a certain amount of static electricity and other technologies, ozone production is relatively small, daily use need not worry. But there is no guarantee that there will be no risk of similar quality and failure after long use. The risks are more or less certain, so why do so many manufacturers use such technology?
大部分用负离子噱头忽悠人的都是日企，但也有少数像豹米这种原本好好的非要闲得蛋疼不学好的。
Most of the people who use negative ion gimmicks are Japanese, but there are a few that are just as boring and boring as the leopard rice.
为什么说“纯物理”是三观正确的？
Why is "pure physics" right?
静电等非“纯物理”技术讨厂商欢心的答案很简单：能节约成本多赚钱。
The answer to non-" pure physical "technology, such as static electricity, is simple: it saves costs and makes more money.
纯物理的空净，采用HEPA滤网+活性炭，是目前空净产品中最成熟的技术，但有一个缺点，就是价格太透明了 —— 用什么等级的产品，成本多少，售价多少，一目了然，普通用户只要会比较数字大小，都能简单的做横向对比来评测哪个产品的性价比高，哪个比较黑心。这么没主动权的地位，电器厂商们怎么能忍？
Pure physical empty net, the HEPA filter and activated carbon, is the most mature technology in the current empty net products, but there is a fault, is the price too transparent - what kind of grades of products, cost how many, how much price, be clear at a glance, the average user as long as will have digital size, can do simple horizontal contrast to review which products cost-effective, which is "dirty". How can appliance manufacturers tolerate such a lack of initiative?
厂商使用类似静电技术的原因，除了编造噱头外，大多是为了在不增加成本的条件下，实现更高，更漂亮的净化数值。可以花更少的钱，少用滤芯，也不用那么纠结电机的噪音问题了。
The reason that manufacturer USES similar electrostatic technique, except make up gimmick, mostly is to achieve higher, more beautiful purify value in the condition that does not increase cost. You can spend less, use fewer filters, and don't worry about the noise of the motor.
但对于我们这些用户来说，这些使用静电等技术来辅助HEPA的空净，价格并没有相对更便宜，有的甚至更贵。一些非纯物理净化产品的滤芯反而更容易报废，例如blueair的用户就必须承担半年更换一次滤芯的代价。
But for our users, these techniques, such as static electricity, are used to support HEPA's emptiness, and prices are not relatively cheap, or even more expensive. Some non-pure physical purifying products are more likely to be scrapped, such as blueair users who have to pay for a half-year replacement.
这些静电技术的本质，是让用户承担或高或低的风险，甚至更高的使用成本。而将这些风险或成本转化成了厂家的利润，所以这不是技术问题，是三观问题。
The essence of these electrostatic techniques is to make users assume the risks of high or low costs, even higher costs. These risks or costs are converted into profits, so this is not a technical problem, it is a three-way problem.
这时候就要夸一下小米了，的确小米空净的问题很多，也时常犯一些抄袭设计，欺瞒用户的脑残错误，但整体的设计还是很规矩的。而且小米的产品定价可以充分的反映出一个行业的生产成本应该是多少。小米的手机、空净、智能手环等等，很多产品都有这样的“定价功能”：当小米进入一个行业之后，往往就会把那些虚高的产品衬托暴露出来。
At this time, I would like to boast about xiaomi. It is true that xiaomi has a lot of problems, and it often makes some plagiarized designs, which can deceive users' brain errors, but the overall design is still very formal. And xiaomi's product pricing can fully reflect how much an industry's production costs should be. Millet mobile phone, an empty net, intelligent hand ring, etc., many products have such pricing function: after entering an industry when millet, foil those inflated products tends to be exposed.
当小米用699做到300的CADR，用1499做到500的CADR，再看看那些挂着七八千的价格，叫嚣着自己来自海外，用了一堆七七八八的奇怪技术，但净化效率还不如小米的品牌，后者到底有多少利润空间，我们自己心理就有数了。
When millet CADR in 699 to 300, with 1499 to 500 the CADR, look at the price, those who hang QiBaQian vociferously himself from overseas, with a lot of strange technology from the 7788, but the purification efficiency is not as good as millet brand, the latter how much profit space, we own several psychological.
哪些是纯物理空气净化器？
Which are pure physical air purifiers?
扣除掉普遍犯病的日系品牌，纯物理类的空气净化器也还是很多的，比如常见的：IQAir，小米，飞利浦，Coway，Honeywell，352，安利等等品牌。
In the case of the ubiquitous Japanese brand, pure physical air purifiers are also plentiful, such as: IQAir, xiaomi, philips, Coway, Honeywell, 352, amway and so on.
不过不同品牌不同型号之间肯定有差异，现在市场上的空净品牌也是鱼龙混杂，具体配置还是以咨询厂家为准。不过如果一个空净在HEPA滤网和活性炭外，加了一些奇怪的你看不懂的技术，那就打个问号吧。
However, there are certain differences between different models of different brands. Now, the empty net brand in the market is also a mixture of fish and dragons, and the specific configuration is based on the consulting manufacturer. But if you have an empty net on the HEPA filter and activated carbon, add some strange technology that you don't understand, then call a question mark.
我们推荐什么空净？
What do we recommend?
1. 纯物理净化的，至少这些品牌的三观比较正。
1. Pure physical purification, at least those brands have a positive outlook.
2. 进口洋品牌并不一定更好。在空净产品上歧视国货完全没意义，只会伤害自己钱包。经过几年的积累，已经有不少值得我们购买的国产品牌出现。
Importing foreign brands is not necessarily better. It makes no sense to discriminate against a country on an empty net, only to hurt your wallet. After several years of accumulation, there are many domestic brands that are worth purchasing.
空净行业是一个比较特殊的行业：中国是现在唯一受到严重雾霾污染，并且居民普遍有经济实力购买空气净化器的国家，是空净唯一的重要市场。国外产品，即便是老字号们，面对我们的雾霾也没有更多的经验：国外空净要不是针对实验室除尘的高端设备，就是日系这种针对花粉过敏问题设计出来的产品，真正面对中国销售的，往往是国外没有的型号，或者干脆就是一些“特供中国”的所谓洋品牌。
Empty net industry is a special industry, China is now the only serious smog pollution, and residents generally have economic strength to buy air purifier, is the only important market empty net. Foreign products, even the old, in the face of our fog no more experience: foreign empty net dust removal of high-end equipment, if it weren't for laboratory is Japanese product of this designed for pollen allergy problem, really selling in China, no models tend to be abroad, or just some of the so-called "special supply China" brand.
3. 记得选择高CADR（洁净空气输出率）和CCM（累积净化量）的空净。
3. Remember to select high CADR (clean air output rate) and CCM (cumulative purification).
不要看广告上写的适用于多少平米，那个数是绝对理想环境下的，比汽车理想油耗还假。几乎所有空净都存在的问题是，最大风档的噪音是让人无法接受的。日常正常使用的时候，都是用中低风档，再加上屋内存在的各种障碍物，因此需要尽量选择更高CADR值的产品，这样在中低风档的时候才可以实现有效的净化效果。
Don't look at the number of square meters that are written on the AD. The number is absolute ideal, and it is more false than the ideal fuel consumption of the car. The problem with almost all empty space is that the most violent noise is unacceptable. Daily normal use, with low wind, coupled with the room of all kinds of obstacles, so you need to try to choose a higher CADR value of products, in the middle and lower damper can effectively only when purifying effect.
一般来说，CADR值建议至少要大于300，对于DYSON这种CADR低到都不好意思标出来的电风扇产品，当玩具可以，别真拿来当净化器。
Generally speaking, the CADR value proposition is more than 300. For DYSON, this CADR is so low that it is difficult to label the fan products. When the toy can, don't really use it as a purifier.
Dyson这种售价四五千的“净化器”，明显就是看到中国净化器市场太赚钱，不黑中国人一把心里过意不去而设计出来的。
Dyson's $45, 000 "purifier" is an obvious way to see the Chinese purifier market making too much money.
除了CADR外，用来衡量滤芯寿命的CCM等级也是要看的。
In addition to CADR, the CCM level used to measure the life of the filter element is also required.
4. 选择对标产品横向对比。
4. Select the horizontal comparison of the product.
对于不差钱的土豪，永远的建议就是闭着眼买IQ，最省心。而普通人就还是多比较几个产品再说。当你不会被那些奇怪的噱头忽悠后，对比空气净化器要看的无非就是下面几项关键数据。可以拿你考虑的空净和小米或者352X80的数据比一下：
For the tuhao of money, always advice is to close your eyes to buy IQ, the most convenient. And the average person is still more than a few products. When you don't get caught up in the odd gimmicks, the comparison of air purifiers is nothing more than the following key data. Compare the data you consider with either xiaomi or 352X80.
CADR值小于等于500的产品，可以跟小米进行对比，虽然小米也问题一大堆，但是699和1599的价格的确没什么水分。而在CADR超过500的机器中，352是个价格较实在的标准参照物。
The CADR value is less than or equal to 500 products, which can be compared with xiaomi. Although xiaomi also has a lot of problems, the price of 699 and 1599 is really not much water. Of the more than 500 machines in CADR, 352 is a more realistic standard.
比如你想买客厅用的飞利浦，352X80的对应型号是7000系列，定价差不多是7999，飞利浦在甲醛过滤能力上有明显的优势，所以你需要考虑这个优势是否值得你花3台352的钱去买。
You want to buy a sitting room with philips, for example, the corresponding models are 7000 series of 352 x80, pricing is almost 7999, philips has obvious advantages on formaldehyde filter ability, so you need to consider whether the advantage is worth you spend money to buy 3 units of 352.
当然小米和352都有各自的问题：小米的噪音和滤芯寿命；352和IQair这种顶部平行出风的结构，会直接把风吹到旁边坐着的人脸上，让很多人不舒服。还好现在有越来越多新的国内品牌，价格相对合理，性能质量也都比较靠谱。我们可以在越来越多的选项中对比和选择适合自己的产品。相信国外暴利品牌肆无忌惮赚中国人雾霾国难财的日子应该不会太久了。
Of course, xiaomi and 352 have their own problems: xiaomi's noise and filter life; At the top parallel to the wind, the structure of the top, the IQair, blows directly into the face of the person sitting next to it, leaving many uncomfortable. Fortunately, there are more and more new domestic brands, the price is relatively reasonable, the performance quality is also reliable. We can compare and choose the products that suit us in more and more options. It shouldn't be too long to believe that foreign profiteering brands can make money from China's smog.
需要提一句去年开始流行的新风产品，从大方向来讲，新风比空净更能直接、全面和良好的解决我们室内空气污染问题。但就和前几年的空净产品一样，国外产品在国内水土不服，国内产品还不成熟，技术比较乱，价格也有太多的水分。我们选择先不推荐，等到有性价比贴心的产品再说。
We need to mention a new wind product that began to be popular last year. In the general direction, the new wind is more direct, more comprehensive and a good solution to the indoor air pollution problem. But just like the empty net products of previous years, foreign products are not satisfied with domestic soil and water, domestic products are not mature, the technology is more disorderly, the price also has too much moisture. We choose not to recommend first, wait until there is a cost-effective product.
对了，我们今年也不会开团空净，原因很简单，我们不愿意团那些卖一台就能赚上千块的暴利产品。而我们喜欢的那些性价比高的产品，又没有什么价格下调的空间可以开团，大家直接在官方渠道买就好。所以干脆不团就好了。
By the way, we're not going to be open this year, for the simple reason that we don't want to sell a profiteering product that can make thousands of dollars. And we like the products with high cost performance, and there is no room for price reduction, so you can buy it directly in official channels. So it's just fine.
The comparison and evaluation of PM2.5 detector will wait a few more days.
我们在去年关于如何对比空气净化器的文章中，提到过选择空气净化器最重要的标准，就是“纯物理”。在我们看来，纯物理是必须的保底选项。很多读者留言问blueair，远大等产品如何？抱歉，我们认为对比非纯物理的空净没有意义，因此就不分析了具体产品了。今天来解释一下为什么。
In our article on how to compare air purifiers last year, we mentioned that the most important criterion for selecting air purifiers is "pure physics". In our view, pure physics is a necessary bottom-line option. A lot of readers asked blueair, what about big products? Sorry, we don't think it makes sense to compare the empty space of non-pure physics, so we don't analyze the specific products. Let me explain why.

而相对非纯物理空净，指的是没有使用滤网，或者在滤网之外使用其他技术，比如最近流行的高压静电集尘技术，此外当然还有日系厂家可能会编造出的各种奇葩名字的技术，如X离子，X因子，XX能等等。
And relatively than purely physical empty net, refers to the screen is not used, or outside of the filter using other techniques, such as the recent popularity of high voltage electrostatic dust collection technology, in addition of course, the Japanese manufacturers could invent all kinds of exotic names of technology, such as ion, X X factor, XX, and so on.
即便是日系净化器中相对靠谱的夏普也患有X离子脑残综合征。
Even the relatively reliable sharpe of Japanese purifiers suffers from the X ion brain injury syndrome.
静电等技术
electrostatics
使用这些技术的主要目的是为了用静电吸附的原理加强颗粒物过滤的效果，或者用负离子/臭氧，或静电等技术杀菌、除味，去除有机污染物等等。
Using these techniques, the main purpose is to use the principle of electrostatic adsorption, enhance the effect of the particle filter, or use/ozone and anion or electrostatic technology such as sterilization, in addition to flavor, removal of organic pollutants and so on.
既然静电吸附技术这么好用，为什么大家不都像什么贝昂、远大一样，搞无耗材纯静电过滤器呢？原因很简单，高压静电类的技术，必然会产生一种比PM2.5还烦人的空气污染物：臭氧。
Since electrostatic adsorption technology works so well, why don't all of us have the same kind of pure electrostatic filter? The reason is simple, the technology of high voltage static electricity, must produce a kind of air pollutant that is more than PM2.5 also: ozone.
和当红的雾霾相比，臭氧危害会被很多人忽视。臭氧是一种强氧化剂，虽然在大气层上面飘着的臭氧层可以帮我们抵御紫外线的伤害。但地面的臭氧污染则会造成我们哮喘、支气管炎、心脏病等心肺疾病，甚至危害生命。
Compared with the red haze, ozone damage is ignored by many people. Ozone is a powerful oxidant, although the ozone layer that floats above the atmosphere can help us resist ultraviolet radiation. But ground-level ozone pollution can cause heart and lung diseases such as asthma, bronchitis, heart disease, and even life.
高压静电技术一定会产生臭氧，只是多少的问题。国家对于电器产生臭氧的浓度有要求，所以一般情况下，这些厂家会在机器中加一层还原层，用来还原机器生成的臭氧，以达到国标，通过检测。
High voltage static technology is sure to produce ozone, just how many problems. Countries have asked to electrical produces ozone concentration, so in general, the manufacturer will add a layer of reduction zone of the machine, used to generate ozone reduction machine, in order to reach national standard, through the test.
贝昂这类高压静电产品据说可以省耗材，但CADR非常低，价格也往往卖得比换十年的滤网还贵。
Such high-voltage electrostatic products are said to be able to save energy, but CADR is very low and prices tend to be more expensive than those for a decade.
满足国标，仍然无法让我们减弱对这个技术的反感。因为世界上不存在永远不会出问题，不会损坏的电器。没有厂家可以保障出厂合格率是绝对的100%，也更不可能保证用户使用1个月，1年，2年，5年之后，绝对没有故障，绝对不会出现臭氧超标的问题。
Meeting the national standard still does not allow us to weaken our aversion to this technology. Because there is no such thing as a problem in the world. No one can guarantee the factory qualified rate is 100% of the absolute, is more impossible to ensure that the user use 1 months, 1 year, 2 years, five years later, there is absolutely no fault, absolutely won't appear the problem of excess ozone.
一般的纯物理净化器，出了问题无非是噪音大点，工作效率低点......但使用静电等技术的产品，就会有造成臭氧超标的风险。那些厂家敢保证10年之后，没有一台机器臭氧超标么？当然不会。那我们凭什么要去赌人品呢？
General pure physical purifier, the problem is no more than noise, work efficiency low... But using technology such as static electricity, there is a risk of excessive ozone. After 10 years, are there any machines that don't have excessive ozone? Of course not. Why should we bet on people?
至于像blueair，日系净化器及类似这种的净化器，使用一定的静电等技术，臭氧生成量相对较少，日常使用不需要担心。但同样无法保证不会有在长时间使用后绝对不会出现类似质量和故障导致的风险。风险或多或少一定存在，那为什么有这么多厂家使用这样的技术呢？
As for blueair, daily purifiers and similar purifiers, the use of a certain amount of static electricity and other technologies, ozone production is relatively small, daily use need not worry. But there is no guarantee that there will be no risk of similar quality and failure after long use. The risks are more or less certain, so why do so many manufacturers use such technology?
大部分用负离子噱头忽悠人的都是日企，但也有少数像豹米这种原本好好的非要闲得蛋疼不学好的。
Most of the people who use negative ion gimmicks are Japanese, but there are a few that are just as boring and boring as the leopard rice.
为什么说“纯物理”是三观正确的？
Why is "pure physics" right?
静电等非“纯物理”技术讨厂商欢心的答案很简单：能节约成本多赚钱。
The answer to non-" pure physical "technology, such as static electricity, is simple: it saves costs and makes more money.
纯物理的空净，采用HEPA滤网+活性炭，是目前空净产品中最成熟的技术，但有一个缺点，就是价格太透明了 —— 用什么等级的产品，成本多少，售价多少，一目了然，普通用户只要会比较数字大小，都能简单的做横向对比来评测哪个产品的性价比高，哪个比较黑心。这么没主动权的地位，电器厂商们怎么能忍？
Pure physical empty net, the HEPA filter and activated carbon, is the most mature technology in the current empty net products, but there is a fault, is the price too transparent - what kind of grades of products, cost how many, how much price, be clear at a glance, the average user as long as will have digital size, can do simple horizontal contrast to review which products cost-effective, which is "dirty". How can appliance manufacturers tolerate such a lack of initiative?
厂商使用类似静电技术的原因，除了编造噱头外，大多是为了在不增加成本的条件下，实现更高，更漂亮的净化数值。可以花更少的钱，少用滤芯，也不用那么纠结电机的噪音问题了。
The reason that manufacturer USES similar electrostatic technique, except make up gimmick, mostly is to achieve higher, more beautiful purify value in the condition that does not increase cost. You can spend less, use fewer filters, and don't worry about the noise of the motor.
但对于我们这些用户来说，这些使用静电等技术来辅助HEPA的空净，价格并没有相对更便宜，有的甚至更贵。一些非纯物理净化产品的滤芯反而更容易报废，例如blueair的用户就必须承担半年更换一次滤芯的代价。
But for our users, these techniques, such as static electricity, are used to support HEPA's emptiness, and prices are not relatively cheap, or even more expensive. Some non-pure physical purifying products are more likely to be scrapped, such as blueair users who have to pay for a half-year replacement.
这些静电技术的本质，是让用户承担或高或低的风险，甚至更高的使用成本。而将这些风险或成本转化成了厂家的利润，所以这不是技术问题，是三观问题。
The essence of these electrostatic techniques is to make users assume the risks of high or low costs, even higher costs. These risks or costs are converted into profits, so this is not a technical problem, it is a three-way problem.
这时候就要夸一下小米了，的确小米空净的问题很多，也时常犯一些抄袭设计，欺瞒用户的脑残错误，但整体的设计还是很规矩的。而且小米的产品定价可以充分的反映出一个行业的生产成本应该是多少。小米的手机、空净、智能手环等等，很多产品都有这样的“定价功能”：当小米进入一个行业之后，往往就会把那些虚高的产品衬托暴露出来。

When millet CADR in 699 to 300, with 1499 to 500 the CADR, look at the price, those who hang QiBaQian vociferously himself from overseas, with a lot of strange technology from the 7788, but the purification efficiency is not as good as millet brand, the latter how much profit space, we own several psychological.

不要看广告上写的适用于多少平米，那个数是绝对理想环境下的，比汽车理想油耗还假。几乎所有空净都存在的问题是，最大风档的噪音是让人无法接受的。日常正常使用的时候，都是用中低风档，再加上屋内存在的各种障碍物，因此需要尽量选择更高CADR值的产品，这样在中低风档的时候才可以实现有效的净化效果。
Don't look at the number of square meters that are written on the AD. The number is absolute ideal, and it is more false than the ideal fuel consumption of the car. The problem with almost all empty space is that the most violent noise is unacceptable. Daily normal use, with low wind, coupled with the room of all kinds of obstacles, so you need to try to choose a higher CADR value of products, in the middle and lower damper can effectively only when purifying effect.
一般来说，CADR值建议至少要大于300，对于DYSON这种CADR低到都不好意思标出来的电风扇产品，当玩具可以，别真拿来当净化器。
Generally speaking, the CADR value proposition is more than 300. For DYSON, this CADR is so low that it is difficult to label the fan products. When the toy can, don't really use it as a purifier.
Dyson这种售价四五千的“净化器”，明显就是看到中国净化器市场太赚钱，不黑中国人一把心里过意不去而设计出来的。
Dyson's $45, 000 "purifier" is an obvious way to see the Chinese purifier market making too much money.
除了CADR外，用来衡量滤芯寿命的CCM等级也是要看的。
In addition to CADR, the CCM level used to measure the life of the filter element is also required.
4. 选择对标产品横向对比。
4. Select the horizontal comparison of the product.
对于不差钱的土豪，永远的建议就是闭着眼买IQ，最省心。而普通人就还是多比较几个产品再说。当你不会被那些奇怪的噱头忽悠后，对比空气净化器要看的无非就是下面几项关键数据。可以拿你考虑的空净和小米或者352X80的数据比一下：
For the tuhao of money, always advice is to close your eyes to buy IQ, the most convenient. And the average person is still more than a few products. When you don't get caught up in the odd gimmicks, the comparison of air purifiers is nothing more than the following key data. Compare the data you consider with either xiaomi or 352X80.
CADR值小于等于500的产品，可以跟小米进行对比，虽然小米也问题一大堆，但是699和1599的价格的确没什么水分。而在CADR超过500的机器中，352是个价格较实在的标准参照物。
The CADR value is less than or equal to 500 products, which can be compared with xiaomi. Although xiaomi also has a lot of problems, the price of 699 and 1599 is really not much water. Of the more than 500 machines in CADR, 352 is a more realistic standard.
比如你想买客厅用的飞利浦，352X80的对应型号是7000系列，定价差不多是7999，飞利浦在甲醛过滤能力上有明显的优势，所以你需要考虑这个优势是否值得你花3台352的钱去买。
You want to buy a sitting room with philips, for example, the corresponding models are 7000 series of 352 x80, pricing is almost 7999, philips has obvious advantages on formaldehyde filter ability, so you need to consider whether the advantage is worth you spend money to buy 3 units of 352.
当然小米和352都有各自的问题：小米的噪音和滤芯寿命；352和IQair这种顶部平行出风的结构，会直接把风吹到旁边坐着的人脸上，让很多人不舒服。还好现在有越来越多新的国内品牌，价格相对合理，性能质量也都比较靠谱。我们可以在越来越多的选项中对比和选择适合自己的产品。相信国外暴利品牌肆无忌惮赚中国人雾霾国难财的日子应该不会太久了。
Of course, xiaomi and 352 have their own problems: xiaomi's noise and filter life; At the top parallel to the wind, the structure of the top, the IQair, blows directly into the face of the person sitting next to it, leaving many uncomfortable. Fortunately, there are more and more new domestic brands, the price is relatively reasonable, the performance quality is also reliable. We can compare and choose the products that suit us in more and more options. It shouldn't be too long to believe that foreign profiteering brands can make money from China's smog.
需要提一句去年开始流行的新风产品，从大方向来讲，新风比空净更能直接、全面和良好的解决我们室内空气污染问题。但就和前几年的空净产品一样，国外产品在国内水土不服，国内产品还不成熟，技术比较乱，价格也有太多的水分。我们选择先不推荐，等到有性价比贴心的产品再说。
We need to mention a new wind product that began to be popular last year. In the general direction, the new wind is more direct, more comprehensive and a good solution to the indoor air pollution problem. But just like the empty net products of previous years, foreign products are not satisfied with domestic soil and water, domestic products are not mature, the technology is more disorderly, the price also has too much moisture. We choose not to recommend first, wait until there is a cost-effective product.
对了，我们今年也不会开团空净，原因很简单，我们不愿意团那些卖一台就能赚上千块的暴利产品。而我们喜欢的那些性价比高的产品，又没有什么价格下调的空间可以开团，大家直接在官方渠道买就好。所以干脆不团就好了。
By the way, we're not going to be open this year, for the simple reason that we don't want to sell a profiteering product that can make thousands of dollars. And we like the products with high cost performance, and there is no room for price reduction, so you can buy it directly in official channels. So it's just fine.
