It is food grade material?
There are a lot of reports before, if the use of hot water pot body 304 food grade material, use for a long time will cause certain harm to people, it has attracted more and more people concern for filter using a series of kettle.
However, some of the filter is made of food grade 304 stainless steel kettle, but some have been replaced with the high manganese steel.
Although manganese is an indispensable trace elements in human body, but the long-term use of this kind of material will release of heavy metals in the filter kettle, because long-term high temperature manganese easier to precipitate, the heavy metals harmful to human body, and even lead to memory impairment.
