UTim Heffernan ngumbhali othetha ngemiba yomgangatho womoya namanzi kunye nobuchwepheshe bamandla obuzinzileyo. Ukuvavanya abacoci, ukhetha ukusebenzisa umsi ohambelana nophawu lweFlare.
Umsitho we-Amazon Prime Day ka-Okthobha ufikile! Apha siqokelele zonke iingcebiso ezibalulekileyo ezivela kwi-Wirecutter.
Sikwafake ukhetho oluhle kakhulu, iCyclopure Purefast, isihluzi esihambelana neBrita esiqinisekiswe yi-NSF/ANSI ukunciphisa iPFAS.
Ukuba ufuna indlela elula yokufumana amanzi okusela ahluziweyo ekhaya, sicebisa iBrita Elite Filter edityaniswe neBrita Standard Daily 10-cup pitcher okanye (ukuba ikhaya lakho lisebenzisa amanzi amaninzi) iBrita 27-cup pitcher. Isixhobo sokuhambisa amanzi iUltramax. Kodwa ngaphambi kokuba ukhethe nasiphi na kuzo, yazi ukuba emva kweminyaka ephantse ibe lishumi yophando malunga nokuhluzwa kwamanzi ekhaya, sikholelwa ukuba izihluzi ezingaphantsi kwesinki okanye ezingaphantsi kwefaucet zezona zilungileyo. Zihlala ixesha elide, zinika amanzi acocekileyo ngokukhawuleza, zinciphisa ungcoliseko, azinakwenzeka ukuba zivale, kwaye zithatha imizuzu embalwa kuphela ukuzifaka.
Le modeli ineziqinisekiso ze-ANSI/NSF ezingaphezu kwama-30—ngaphezu kwanoma yisiphi isihluzo esikudidi lwayo—kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzo, inokuvaleka.
I-Brita kettle ephawulekayo ichaza kakhulu udidi lwe-filter kettle kwaye kulula ukuyisebenzisa nokuyigcina icocekile kunezinye iimodeli ezininzi zaseBrita.
Isixhobo sokuhambisa amanzi saseBrita sigcina amanzi aneleyo ngosuku kusapho olukhulu, kwaye impompo yaso engavuziyo kulula ukuyisebenzisa ebantwaneni.
I-LifeStraw Home Water Dispenser ivavanywe ngokuthembekileyo ukususa izinto ezininzi ezingcolisayo, kuquka ne-lead, kwaye isihluzo sayo asivali kakhulu kunaso nasiphi na esinye isixhobo esisivavanyeyo.
Izinto zokucoca i-Dexsorb zivavanywa ngokwemigangatho ye-NSF/ANSI kwaye zibamba ngokufanelekileyo uluhlu olubanzi lweekhemikhali ezihlala zihleli (PFAS), kubandakanya i-PFOA kunye ne-PFOS.
Le modeli ineziqinisekiso ze-ANSI/NSF ezingaphezu kwama-30—ngaphezu kwanoma yisiphi isihluzo esikudidi lwayo—kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzo, inokuvaleka.
Eyona filter yeBrita isebenzayo sisihluzo seBrita Elite. Siqinisekiswe yi-ANSI/NSF kwaye sihluza izinto ezingcolisayo ezininzi kunaso nasiphi na esinye isihluzo esisivavanyeyo; ezi ziquka i-lead, i-mercury, i-cadmium, i-PFOA kunye ne-PFOS, kunye noluhlu olubanzi lweekhompawundi zoshishino ezifumaneka ngakumbi emanzini empompi. Kukho "izinto ezintsha ezingcolisayo". Inokuhlala iigaloni ezili-120 okanye iinyanga ezintandathu, nto leyo ephindwe kathathu kunobomi obulinganisiweyo kwezinye izihluzi ezininzi. Ekuhambeni kwexesha, oku kunokwenza isihluzo se-Elite sibe nexabiso eliphantsi kunesihluzo esiqhelekileyo seenyanga ezimbini. Nangona kunjalo, ngaphambi kokuba kudlule iinyanga ezintandathu, inkunkuma emanzini inokuyivala. Ukuba uyazi ukuba amanzi akho empompi acocekile kodwa ufuna nje ukuba abe nencasa engcono, ingakumbi ukuba ivumba njenge-chlorine, isihluzo samanzi esiqhelekileyo seBrita kunye nesihluzo samanzi sibiza kancinci kwaye asinakukwazi ukuvala, kodwa asinasiqinisekiso sokuba i-lead okanye nayiphi na ikhompawundi zoshishino.
I-Brita kettle ephawulekayo ichaza kakhulu udidi lwe-filter kettle kwaye kulula ukuyisebenzisa nokuyigcina icocekile kunezinye iimodeli ezininzi zaseBrita.
Phakathi kweebhotile zamanzi ezininzi zaseBrita, esithanda kakhulu yiBrita Standard Everyday Water Bottle 10 Cup. Uyilo olungenaziphazamiso noluqhekekayo lwenza ukucoca kube lula kunezinye iimbiza zaseBrita, kwaye isiciko sesandla esinye senza ukugcwalisa kwakhona kube lula nangakumbi. Isiphatho saso esigobileyo esimile okwe-C sikwakhululekile kunesiphatho esimile okwe-engile esifumaneka kwiibhotile ezininzi zaseBrita.
Isixhobo sokuhambisa amanzi saseBrita sigcina amanzi aneleyo ngosuku kusapho olukhulu, kwaye impompo yaso engavuziyo kulula ukuyisebenzisa ebantwaneni.
Isixhobo sokuhambisa amanzi saseBrita Ultramax siphatha malunga neekomityi ezingama-27 zamanzi (iikomityi ezili-18 kwidama lokucoca kunye nezinye iikomityi ezili-9 okanye ezili-10 kwidama eliphezulu). Uyilo lwaso oluncinci lugcina indawo efrijini, kwaye impompo ivala ngokuzenzekelayo emva kokugalela ukuthintela ukugcwala. Le yindlela elula yokuba namanzi abandayo ahluziweyo aneleyo.
I-LifeStraw Home Water Dispenser ivavanywe ngokuthembekileyo ukususa izinto ezininzi ezingcolisayo, kuquka ne-lead, kwaye isihluzo sayo asivali kakhulu kunaso nasiphi na esinye isixhobo esisivavanyeyo.
Sisebenzise iilitha eziyi-2.5 zamanzi angcoliswe ngumhlwa kakhulu ngesixhobo sokuhambisa amanzi ekhaya iLifeStraw, kwaye nangona amanzi ehle kancinci ukuya esiphelweni, ukuhluzwa akuzange kume. Abo baye bahlangabezana nokuxinana kwezinye izihluzi zamanzi (kuquka iBrita Elite yethu ekhethiweyo) okanye abafuna isisombululo samanzi amdaka okanye amdaka empompini, esi sihluzi sikhetho lwethu olucacileyo. ILifeStraw ikwanazo neziqinisekiso ezine ze-ANSI/NSF (i-chlorine, incasa nevumba, i-lead kunye ne-mercury) kwaye ivavanywe ngokuzimeleyo yilabhoratri eqinisekisiweyo ukuhlangabezana nemigangatho emininzi eyongezelelweyo yokucoca ukungcola kwe-ANSI/NSF.
Izinto zokucoca i-Dexsorb zivavanywa ngokwemigangatho ye-NSF/ANSI kwaye zibamba ngokufanelekileyo uluhlu olubanzi lweekhemikhali ezihlala zihleli (PFAS), kubandakanya i-PFOA kunye ne-PFOS.
Izihluzi zeCyclopure Purefast zisebenzisa izinto ezifanayo zeDexsorb ezisetyenziswa kwezinye izitishi zokucoca amanzi amdaka ukususa iikhemikhali (PFAS) ngokusisigxina kwimithombo yamanzi kawonke-wonke. Zihambelana neejagi zethu zeBrita kunye nezihluzi ezicetyiswayo. Zilinganiswa kwiigaloni ezingama-65 kwaye zihluza ngokukhawuleza kwiimvavanyo zethu kwaye azinciphisi kakhulu ngokuhamba kwexesha, nangona njengakwesiphi na isihluzi somxhuzulane, ukuba kukho inkunkuma eninzi emanzini inokuvaleka. Isihluzi siza nephakheji ehlawulelwayo; thumela isihluzi esisetyenzisiweyo kwiCyclopure kwaye inkampani iya kusicubungula ukuze sitshabalalise nayiphi na iPFAS ebanjiweyo ukuze ingasayi kungena kwindawo engqongileyo. IBrita ngokwayo ayikhuthazi ukusetyenziswa kwezihluzi zomntu wesithathu, kodwa ngenxa yokuba zombini izihluzi zePurefast kunye nezinto zeDexsorb ziqinisekisiwe yi-NSF/ANSI ukunciphisa iPFAS, siqinisekile ukuba siya kuzicebisa. Qaphela ukuba ibamba kuphela iPFAS kunye nechlorine. Ukuba ukhathazekile ngezinye izinto, cinga ngeBrita Elite;
Ndisoloko ndivavanya izihluzo zamanzi zeWirecutter ukusukela ngo-2016. Kwingxelo yam, ndithethe ixesha elide ne-NSF kunye ne-Water Quality Institute, imibutho emibini emikhulu yokuqinisekisa izihluzo eMelika, ukuze ndiqonde indlela oluqhutywa ngayo uvavanyo lwabo. Ndidlan’ udliwanondlebe nabameli abavela kubavelisi abaninzi bezihluzo zamanzi ukuze ndiphikisane namabango abo. Ndisebenzise izihluzo kunye neepitcher ezininzi kule minyaka idlulileyo kuba ukuqina ngokubanzi, ukulula kunye neendleko zokugcinwa, kunye nobuhlobo bomsebenzisi konke oku kubaluleke kakhulu kwinto oyisebenzisayo amaxesha amaninzi ngemini.
Owayesakuba yingcali ye-NOAA uJohn Holecek uphande waza wabhala inguqulelo yangaphambili yesi sikhokelo, wenza uvavanyo lwakhe, waza wayalela olunye uvavanyo oluzimeleyo.
Esi sikhokelo senzelwe abo bafuna isihluzo samanzi esifana ne-pitcher esizalisa amanzi empompini yabo size siwagcine efrijini.
Inzuzo yesihluzo sepitcher kukuba kulula ukusisebenzisa. Okufuneka ukwenze kukuzizalisa ngempompo uze ulinde isihluzo sisebenze. Zikwabiza kancinci ukuzithenga, kwaye izihluzo ezitshintshayo (ezidla ngokufuneka rhoqo emva kweenyanga ezimbini) zihlala zibiza ngaphantsi kwe-$15.
Zineengxaki ezininzi. Zinokususa ngokufanelekileyo uluhlu oluncinci kakhulu lwezinto ezingcolisayo kunezinye izihluzi ezingaphantsi kwesinki okanye ezingaphantsi kwephampu kuba zixhomekeke kumxhuzulane kunoxinzelelo lwamanzi, zifuna isihluzi esincinci.
Ukuthembela kumxhuzulane kuthetha ukuba izihluzo zeepitcher ziyacotha: ukuzaliswa kube kanye kwamanzi avela kwidama eliphezulu kungathatha imizuzu emi-5 ukuya kweli-15 ukudlula kwisihluzo, kwaye kudla ngokufuna ukongeza amanzi amaninzi ukuze ufumane i-pitcher epheleleyo yamanzi acocekileyo.
Izihluzi zeejug zihlala zivalekile ngenxa yenkunkuma emanzini empompi okanye kwanamaqamza amancinci omoya avela kwiimpompo zomoya.
Ngenxa yezi zizathu, sicebisa ukuba kufakwe isihluzo phantsi kwesinki okanye kwimpompo ukuba iimeko ziyasifuna.
E-United States, unikezelo lwamanzi kawonke-wonke lulawulwa yi-Environmental Protection Agency (EPA) phantsi koMthetho waManzi okuNwa aKhuselekileyo, kwaye amanzi aphuma kwiindawo zokunyanga amanzi kawonke-wonke kufuneka ahlangabezane nemigangatho engqongqo yomgangatho. Nangona kunjalo, ayizizo zonke izinto ezingcolisayo ezilawulwayo.
Ukongeza, izinto ezingcolisayo zingangena emva kokuba amanzi ephume kwisityalo sokunyanga ngemibhobho evuzayo okanye (kwimeko yelothe) ngokuphuma kwimibhobho ngokwayo. Unyango lwamanzi olwenziwe okanye olungananzwanga kwisityalo lunokwenza kube mandundu nangakumbi ukuphuma kwimibhobho esezantsi, njengoko kwenzekile eFlint, eMichigan.
Ukuze ufumane kanye kanye ukuba yintoni na emanzini omthengisi wakho, unokukhangela kwi-intanethi iNgxelo yokuQiniseka kwaBathengi (i-CCR) yomthengisi wakho wasekuhlaleni evunyiweyo yi-EPA. Ngaphandle koko, bonke abathengisi bamanzi kawonke-wonke kufuneka bakunike ii-CCR zabo xa becela.
Kodwa ngenxa yongcoliseko olunokubakho oluvela ngezantsi, indlela ekuphela kwayo yokufumanisa ukuba yintoni ekwimanzi ekhayeni lakho kukuvavanya. Ilebhu yakho yomgangatho wamanzi ingakwenza oku, okanye ungasebenzisa ikhithi yokuvavanya ekhaya. Sijonge ezili-11 kuzo kwisikhokelo sethu kwaye sichukumisekile yiSimpleLab's Tap Score, elula ukuyisebenzisa kwaye inika ingxelo eneenkcukacha, ebhaliweyo ngokucacileyo yokuba zeziphi izinto ezingcolisayo ezikwimanzi akho empompini.
Uvavanyo lwamanzi lukamasipala oluphambili lweSimpleLab Tap Score lubonelela ngohlalutyo olupheleleyo lwamanzi akho okusela kwaye lubonelela ngeziphumo ezilula ukuzifunda.
Ukuqinisekisa ukuba sicebisa kuphela izihluzi onokuzithemba, kudala sigxininisa ukuba ukhetho lwethu luhlangabezana nomgangatho wegolide: isiqinisekiso se-ANSI/NSF. I-American National Standards Institute (ANSI) kunye neNational Science Foundation (NSF) yimibutho yabucala, engenzi nzuzo esebenza ne-Environmental Protection Agency, abavelisi kunye nezinye iingcali ukuphuhlisa imigangatho yomgangatho oqinileyo kunye nokuvavanya amawaka eemveliso, kubandakanya neenkqubo zamanzi.
Kuphela emva kokusebenzisa iisampulu "zovavanyo", ezazingcoliseke kakhulu kunamanzi amaninzi epompo, apho izihluzi zakwazi ukuhlangabezana nemigangatho yesatifikethi, zidlula kakhulu ixesha lazo lobomi elilindelweyo.
Iilabhoratri ezimbini eziphambili zokuqinisekisa isihluzo samanzi yi-NSF ngokwayo kunye ne-Water Quality Association (WQA). Zombini zivunyiwe ngokupheleleyo yi-ANSI kunye neKhansile yeMigangatho yaseKhanada eMntla Melika kwaye zingenza uvavanyo lwesatifikethi se-ANSI/NSF.
Kodwa emva kweminyaka yengxoxo yangaphakathi, ngoku samkela ulwimi olukhululekileyo oluthi “luvavanywe ngokwemigangatho ye-ANSI/NSF” endaweni yesatifikethi esisemthethweni, phantsi kwemiqathango embalwa engqongqo: Okokuqala, uvavanyo lwenziwa yilabhoratri ezimeleyo, kungekhona yilabhoratri ezimeleyo. Umenzi wezihluzi; okwesibini, ilebhu ngokwayo ivunyiwe yi-ANSI okanye eminye imibutho yesizwe okanye engekho phantsi kukarhulumente ukuba yenze uvavanyo oluqatha ngokwemigangatho emiselweyo; okwesithathu, umenzi utyhila ulwazi malunga nelabhoratri yovavanyo, iziphumo kunye neendlela zayo; Umenzi unamava amaninzi okwenza izihluzi eziye zangqineka zikhuselekile, zithembekile kwaye zichazwe ngokunyaniseka.
Siphinde sayinciphisa ukuya kwiifilitha eziqinisekisiweyo okanye ezilingana ubuncinane nemigangatho emibini ephambili ye-ANSI/NSF (Standard 42 kunye neStandard 53) (egubungela i-chlorine kunye nezinye izinto ezingcolisayo "ezinobuhle" kunye neentsimbi ezinzima ezifana ne-lead, ngokulandelanayo) kunye nee-pesticides. kunye nezinye izinto eziphilayo). Umgangatho omtsha we-401 ugubungela "izinto ezingcolisayo ezivelayo," ezifana namayeza, ezifumaneka ngakumbi emanzini e-United States, yiyo loo nto sinikela ingqalelo ekhethekileyo kwiifilitha.
Saqala ukukhangela iikettles ezidumileyo ezinomthamo weekomityi ezili-10 ukuya kwezili-11 kunye nezikhuphi zamanzi ezinkulu, eziluncedo kakhulu kumakhaya asebenzisa amanzi amaninzi. (Uninzi lweenkampani lukwabonelela ngeepitchers ezincinci kwabo bangafuni modeli ipheleleyo.)
Emva koko sithelekise iinkcukacha zoyilo (kubandakanya isitayile sesiphatho kunye nentuthuzelo), ukulula kokufakela nokutshintsha isihluzo, indawo ethathwa yimbiza kunye nesihluzi efrijini, kunye nomlinganiselo womthamo wetanki yokuzalisa ephezulu kunye netanki "yokucoca" esezantsi. (Okukhona umlinganiselo uphezulu, kokukhona kungcono, kuba uza kufumana amanzi amaninzi ahluziweyo ngalo lonke ixesha usebenzisa itephu.)
Senze uvavanyo oluninzi kwiifilitha ezininzi ngo-2016, sithelekisa iziphumo zethu neesatifikethi ze-ANSI/NSF kunye namabango omenzi. Kwilabhoratri yakhe, uJohn Holecek ulinganise izinga apho isihluzo ngasinye sisusa khona i-chlorine. Kwiindlela zethu ezimbini zokuqala, senze isivumelwano sokuvavanya ngokuzimeleyo ukususa i-lead sisebenzisa izisombululo zongcoliseko lwe-lead ezingaphezulu kakhulu kunezo zifunwa yi-NSF kwisivumelwano sayo sokuqinisekisa.
Into esiyifundayo kuvavanyo lwethu kukuba isiqinisekiso se-ANSI/NSF okanye isiqinisekiso esilinganayo sisalathisi esithembekileyo sokusebenza kwesihluzo. Oku akumangalisi xa ucinga ngendlela engqongqo ngayo imigangatho yesiqinisekiso. Ukususela ngoko, sithembele kwisiqinisekiso se-ANSI/NSF okanye isiqinisekiso esilinganayo ukumisela ukusebenza kwesihluzo esithile.
Uvavanyo lwethu olulandelayo lugxile ekusebenziseni izinto zokwenyani, kunye neempawu ezisebenzayo kunye neentsilelo ezibonakala kuphela xa uqala ukusebenzisa ezi mveliso ngokuhamba kwexesha.
Le modeli ineziqinisekiso ze-ANSI/NSF ezingaphezu kwama-30—ngaphezu kwanoma yisiphi isihluzo esikudidi lwayo—kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzo, inokuvaleka.
Izihluzi zeBrita Elite (ezazikade zibizwa ngokuba yiLonglast+) ziqinisekiswe yi-ANSI/NSF ukuba zichonge izinto ezingaphezulu kwama-30 ezingcolisayo (PDF), kuquka i-lead, i-mercury, i-microplastics, i-asbestos, kunye ne-PFAS ezimbini eziqhelekileyo: i-perfluorooctanoic acid (PFOA) kunye ne-perfluorinated octane sulfonic acid (PFOS). Oku kwenza ukuba ibe sesona sihluzi se-pitcher esiqinisekisiweyo kakhulu esisivavanyeyo, kwaye sisicebisa abo bafuna uxolo lwengqondo.
Kuye kwafunyaniswa ukuba isusa amanye amabala amaninzi aqhelekileyo. Oku kuquka i-chlorine (eyongezwa emanzini ukunciphisa iintsholongwane kunye nezinye izifo kwaye yeyona nto ibangela ukuba amanzi empompini abe nencasa embi); i-carbon tetrachloride, i-compound eguquguqukayo eyonakalisa isibindi kwaye ifumaneka ngakumbi kwiindawo zamanzi; Kufunyenwe “ii-compounds ezintsha,” kuquka i-bisphenol A (BPA), i-DEET (isibulali-zinambuzane esiqhelekileyo) kunye ne-estrone (uhlobo lwe-estrogen oluyilwe).
Nangona uninzi lwee-pitcher filters zinomjikelo wokutshintsha rhoqo ngee-40 gallons okanye iinyanga ezimbini, i-Elite inomjikelo wokutshintsha wee-120 gallons okanye iinyanga ezintandathu. Ngokwethiyori, oku kuthetha ukuba kufuneka usebenzise ii-Elite filters ezimbini kuphela ngonyaka endaweni yezintandathu, nto leyo ebangela inkunkuma encinci kwaye inciphise iindleko zokugcwalisa kwakhona malunga ne-50%.
Kwisihluzo se-pitcher, sisebenza ngokukhawuleza. Kwiimvavanyo zethu, isihluzo esitsha se-Elite sithathe imizuzu emihlanu ukuya kwesixhenxe ukuzalisa. Izihluzo ezifanayo esizivavanyileyo zithatha ixesha elide—ngokuqhelekileyo imizuzu eli-10 nangaphezulu.
Kodwa kukho isilumkiso. Njengazo zonke izihluzi zepitcher, i-Elite inokuvaleka lula, nto leyo enokunciphisa izinga layo lokuhluza okanye ithintele ekuhluzeni ngokupheleleyo, nto leyo ethetha ukuba kuya kufuneka uyitshintshe rhoqo. Abanini abaninzi baye bakhalaza ngale ngxaki, kwaye kuvavanyo lwethu, i-Elite yaqala ukuma ngaphambi kokuba ifikelele kumthamo wayo weegaloni ezili-120. Ukuba unengxaki eyaziwayo ngenkunkuma emanzini akho empompini (idla ngokuba luphawu lwemibhobho erhabaxa), amava akho aya kuba njalo.
Kwaye usenokungadingi lonke ukhuseleko lwabantu abaphezulu. Ukuba uyazi ukuba amanzi akho empompini asemgangathweni olungileyo (oku kungafunyanwa kusetyenziswa isixhobo sokuvavanya amanzi ekhaya), sicebisa ukuba usebenzise i-Brita Standard water dispenser base pitcher kunye nesihluzo. Ineziqinisekiso ze-ANSI/NSF ezintlanu kuphela (PDF), kubandakanya i-chlorine (kodwa hayi i-lead, izinto eziphilayo, okanye izinto ezintsha ezingcolisayo), nto leyo eyahlukileyo kakhulu kwinqanaba lesiqinisekiso esinalo i-Elite. Kodwa sisihluzo esingabizi kakhulu, esingenamida esinokuphucula incasa yamanzi akho.
