1、看標(biao)(biao)簽、選品(pin)牌：購買(mai)飲用水時，消費者(zhe)最(zui)直接的參考就是產(chan)品(pin)標(biao)(biao)簽，按照國家有關(guan)標(biao)(biao)準規(gui)定，標(biao)(biao)簽必須標(biao)(biao)注產(chan)品(pin)名、廠(chang)名、廠(chang)址、生(sheng)產(chan)日(ri)期(qi)、保(bao)質(zhi)期(qi)、執行(xing)標(biao)(biao)準等，礦泉水還要(yao)標(biao)(biao)明(ming)主(zhu)要(yao)成分(fen)指標(biao)(biao)、水源地、國家或(huo)省(sheng)級(ji)的鑒定。

2、看(kan)包裝(zhuang)、忌(ji)貪(tan)便宜：小瓶(ping)裝(zhuang)正品(pin)水一(yi)般瓶(ping)壁厚(hou)薄適中，有彈性，透明(ming)度(du)好且(qie)有光澤，瓶(ping)蓋(gai)上(shang)生產日期清晰完整；劣質品(pin)瓶(ping)壁薄、脆且(qie)彈性差，色澤深，手感粗糙，瓶(ping)蓋(gai)不易一(yi)次性開(kai)啟，嚴重時(shi)有漏氣、漏水現(xian)象(xiang)。

3、考慮用(yong)(yong)(yong)(yong)(yong)水量、選(xuan)擇小(xiao)(xiao)包(bao)裝：飲(yin)用(yong)(yong)(yong)(yong)(yong)水是(shi)(shi)有保(bao)(bao)質(zhi)(zhi)期的(de)，特(te)別是(shi)(shi)開啟后(hou)(hou)保(bao)(bao)質(zhi)(zhi)期更(geng)短，一般要求在(zai)3至5日內用(yong)(yong)(yong)(yong)(yong)完(wan)。現在(zai)市面(mian)上供(gong)家庭(ting)飲(yin)用(yong)(yong)(yong)(yong)(yong)的(de)水大(da)多(duo)為5加侖（18.9升）裝，對于普通(tong)的(de)三(san)口之家來說，很(hen)難在(zai)保(bao)(bao)質(zhi)(zhi)期內用(yong)(yong)(yong)(yong)(yong)完(wan)。因(yin)此，應盡可能選(xuan)購小(xiao)(xiao)包(bao)裝，否則，建議(yi)煮沸(fei)后(hou)(hou)飲(yin)用(yong)(yong)(yong)(yong)(yong)，或(huo)用(yong)(yong)(yong)(yong)(yong)于煮飯、沖茶。
