相信大家在平时
都会有购买过矿泉水的经历
可是你有注意过它们的价格吗
有的是一两块，但也有十几块的
那么它们之间究竟有什么差别呢
其实市面上的矿泉水严格来说应该叫作瓶装水
分为纯净水、天然水、矿物质水和天然矿泉水四种
一、纯净水
纯净水简称净水或纯水，指不含杂质的水
来源于符合生活饮用水卫生标准的自来水
再适当地加工制成、里面不含任何添加物
无色透明，不含有益或有害的物质
市场上的太空水、蒸馏水就属于纯净水
二、天然水
天然水是经过最小限度处理的自然水
或者是地下形成的泉水、自流井水等
并不是由市政系统或公共用水系统引出的
在经过处理之后，去除了水中的有害物质
另外保留了对人体有益的微量和矿物质
是符合人体营养生理功能需求的“健康水”
三、矿物质水
矿物质水是在纯净水的基础上
合理添加了镁钾硫氯等矿物质元素
以城市的自来水为原水
虽然含有“矿物质”
但是主要目的是为了补充水分
而不是营养
四、天然矿泉水
天然矿泉水是指存在岩层中的地下矿水
一般在地层深部循环形成
含有特殊的化学成分和物理性质
也指从地下深处自然涌出或钻井采集的
取水难度比较高，但是营养作用好
有些厂家会承包一个山头来取水
因此价格会稍贵
另外，在我们生活中经常用的桶装水，采用的是自来水或抽取地下水，分为纯净水、矿泉水、矿物质水等，家用的就是纯净水，但是要注意饮水机的卫生消毒。
从以上介绍可以看出，矿泉水有价格高低也是很正常的，它主要是根据水的来源和生产成本标定的，如果采水难度高价格就会高一些，另外，十几元的水可能是国外进口的 ，在质检和生产标准上更加严格、关税也高，当然供货渠道、宣传营销、设备成本等等，都会影响矿泉水的价格。
我们不生产水，我们只是大自然的搬运工。
不同牌子的矿泉水里面包含的矿物质成分以及配量是不同的,这个关系到不同地方开采的水源质量
