廢話不多說，我直接寫信去NSF問到底全機認證是三小，標誌有沒有差，得到的回答節
錄如下:
There are certification marks that are used by all manufacturers who are
certified to NSF International standards and certified by NSF International.
There are color restrictions and size recommendations for the certification
marks. The certification mark by itself does not represent different
certification; but rather the list of standards that the product has been
certified against as well as the list of contaminants it will reduce is a way
to differentiate a product’s certification.
通過NSF標準認證的製造商可以使用認證標誌，有顏色上的限制和建議尺寸。
標誌本身不代表認證不同，產品本身通過的標準認證，以及能降低的汙染列表才能分辨
產品認證的不同。
There are component certifications that we use to verify the components in
contact with drinking water are safe to use. These fall under standard 42
and/or 61. They would state as such “certified for material and structural
integrity only” whereas the performance of a product is verified as a whole
system is under 42, 53, 401, etc.
接觸到飲用水的零部件認證是42和/或61，確保使用安全無虞，認證的描述如:僅認證材
質和結構完整性。產品的效能認證是以完整系統來驗證，例如42、53、401等。
然後我從安麗官網截圖給NSF https://imgur.com/FLHv9OJ.jpg
還有這一堆NSF認證標誌https://imgur.com/Eaji0f7.jpg
The mark is the same with the exception of the box underneath has different
text clarifying the product’s certification.
標誌是相同的，除了底下文字標註認證種類的不同。
The certification mark has a ® with it for all marks including the “
independently certified” version.
認證標誌有®，包括獨立認證版本(官網截圖的TM版不知道哪生出來的)。

結論:只要像42、53、401屬於效能認證本來就是完整全機下去驗，不好意思戳破你們
"全機認證">"零件認證"的話術。
當然也就沒有專屬"全機認證"的標誌，官方也說了標誌有限制顏色，一大堆各
種標誌是一樣的，要查表或標誌才知道認證種類。
以後要是碰到安麗再用"全機認證"、"標誌等級不一樣"話虎爛，歡迎拿這篇去
甩他臉。
完整信件有點長，等有空再放。
下次看有沒有機會放紐崔萊官方打臉版，話唬爛還是官方打臉最對味。
