调查显示,由于担心水资源被污染和自来水的质量不够好。近年来,家用自来水过滤装置越来越普遍,那么这些装置是否对人们的健康完全有益而无害呢?专家们的回答并非如此,如有学者指出安装反向渗透(reverse osmosis)或蒸馏式(distillation)自来水过滤系统,因可有效清除自来水中的氟和其它矿物质(fluoride and other minerals in drinking water)而害于牙齿之健康;相反,大多数活性碳过滤系统(activated carbon systems)因对自来水中的氟无任何清除作用,故不影响牙齿的健康。所以,仅从口腔保健的角度而言,人们应该选择的家用自来水过滤系统应该是活性碳装置,而非反向渗透或蒸馏式过滤系统。
Studies have shown that water filtration systems using reverse osmosis or distillation can effectively reduce or totally remove fluoride and other minerals in drinking water. However, most activated carbon systems do not have any effect on fluoride content of water(from health tips).
