鉛水事件在前陣子大家都大為緊張, 身邊的人都好希望知道自己購買的濾水器是否可去除鉛, 市面上都有很多品牌提到NSF42及NSF53可以去除鉛, 又是否可以呢?
What is NSF43 / NSF 53??
NSF / ANSI 42在過濾系統認證的最低要求,旨在減少可能存在於公共或私人飲用水中的特定美學或非健康相關污染物(氯,味道,氣味和微粒)。
NSF / ANSI 42的範圍包括材料安全性,結構完整性和美學,非健康相關污染物減少性能聲明。該標準解決的最常見的技術是碳過濾。
NSF / ANSI 53制定了旨在減少特定健康相關污染物(如隱孢子蟲,賈第鞭毛蟲,鉛,揮發性有機化學品(VOC)和MTBE(甲基叔丁基醚))的POU / POE過濾系統認證的最低要求,可能存在於公共或私人飲用水中。
NSF / ANSI 53的範圍包括材料安全性,結構完整性和與健康有關的污染物減少性能聲明。該標準解決的最常見的技術是碳過濾。
Filtration
Three NSF standards cover filtration systems: NSF/ANSI 42, NSF/ANSI 53 and NSF/ANSI 401.
NSF/ANSI 42: Drinking Water Treatment Units - Aesthetic Effects
NSF/ANSI 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that may be present in public or private drinking water.
The scope of NSF/ANSI 42 includes material safety, structural integrity and aesthetic, non-health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.
NSF/ANSI 53: Drinking Water Treatment Units - Health Effects
NSF/ANSI 53 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs) and MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.
The scope of NSF/ANSI 53 includes material safety, structural integrity and health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.
