UTim Heffernan ngumbhali ogubungela imiba yomgangatho womoya kunye nomgangatho wamanzi kunye nobuchwepheshe bamandla obuzinzileyo. Ukuvavanya abacoci, ukhetha ukusebenzisa umsi womdlalo we-flare brand.
Umnyhadala woSuku lweNkulumbuso yaseAmazon ulapha! Apha siqokelele zonke iingcebiso ezixabisekileyo kwi-Wirecutter.
Siphinde songeze inketho enkulu, iCyclopure Purefast, isihluzi esithobelayo seBrita esiqinisekiswe yiNSF/ANSI yokunciphisa iPFAS.
Ukuba ujonge eyona ndlela ilula yokufumana amanzi okusela ahluziweyo ekhaya, sicebisa iBrita Elite Filter edityaniswe neBrita Standard Daily 10-cup pitcher okanye (ukuba usapho lwakho lisebenzisa amanzi amaninzi) iBrita 27-komityi yepitha . Ukuhambisa amanzi Ultramax. Kodwa ngaphambi kokuba ukhethe nayiphi na kuzo, yazi ukuba emva kweminyaka elishumi yophando lokuhluza amanzi asekhaya, sikholelwa ukuba izihluzi ezingaphantsi kwe-sinki okanye eziphantsi kwe-faucet lolona khetho lulungileyo. Zihlala ixesha elide, zihambisa amanzi acocekileyo ngokukhawuleza, zinciphisa ungcoliseko, azifane zivale, kwaye zithatha imizuzu kuphela ukuyifaka.
Lo mzekelo unezitifiketi ezingaphezu kwe-30 ze-ANSI / NSF-ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo-kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzi, inokuvalwa.
Utyikityo lweketile yeBrita ichaza ubukhulu becala udidi lweketile yokucoca kwaye kulula ukuyisebenzisa nokugcina icocekile kunezinye iimodeli ezininzi zeBrita.
Isixhobo sokuhambisa amanzi saseBrita sigcina amanzi awoneleyo ngosuku kusapho olukhulu, kwaye impompo yaso engavuziyo ilula ngokwaneleyo ukuba abantwana bayisebenzise.
I-LifeStraw Home Water Dispenser ivavanywa ngokuthembekileyo ukuze isuse ungcoliseko oluninzi, kuquka ilothe, kwaye isihluzo saso asithandeki kakhulu ekuvalelekeni kunaso nasiphi na esinye isixhobo esisivavanyileyo.
Izinto zokucoca i-Dexsorb zivavanywa kwimigangatho ye-NSF/ANSI kwaye ibambe ngokufanelekileyo uluhlu olubanzi lweekhemikhali eziqhubekayo (PFAS), kubandakanya iPFOA kunye nePFOS.
Lo mzekelo unezitifiketi ezingaphezu kwe-30 ze-ANSI / NSF-ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo-kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzi, inokuvalwa.
Esona sihluzo seBrita sisebenza kakuhle sisihluzo seBrita Elite. Yi-ANSI/NSF eqinisekisiweyo kwaye ihluza ungcoliseko ngakumbi kunaso nasiphi na esinye isihluzo esondliwa ngumxhuzulane esikhe savavanya; ezi ziquka i-lead, i-mercury, i-cadmium, i-PFOA kunye ne-PFOS, kunye noluhlu olubanzi lwee-industrial compounds eziye zafunyanwa ngakumbi kumanzi ompompo. “izingcolisi ezintsha” zikhona. Inobomi obuziigaloni ezili-120 okanye iinyanga ezintandathu, nto leyo ebuphinda kathathu ubomi obulinganiselweyo kuninzi lwezinye izihluzi. Ekuhambeni kwexesha, oku kunokwenza isihluzo se-Elite singabizi kakhulu kunesona siqhelekileyo seenyanga ezimbini. Noko ke, ngaphambi kokuba kudlule iinyanga ezintandathu, intlenga esemanzini isenokuyivala. Ukuba uyazi ukuba amanzi akho etephu acocekile kodwa ufuna nje ukuba anencasa ngcono, ngakumbi ukuba inuka njengeklorini, ingqayi yamanzi yaseBrita esemgangathweni kunye nesihluzo sokucoca amanzi sixabisa kancinci kwaye asinakukwazi ukuvaleka, kodwa asiqinisekiswanga. ilothe okanye nayiphi na ikhompawundi yoshishino.
Utyikityo lweketile yeBrita ichaza ubukhulu becala udidi lweketile yokucoca kwaye kulula ukuyisebenzisa nokugcina icocekile kunezinye iimodeli ezininzi zeBrita.
Phakathi kweebhotile ezininzi zamanzi e-Brita, esizithandayo yi-Brita Standard Everyday Water Bottle 10 Cup. Uyilo lwe-no-nooks-and-cracks lwenza ukucoca kube lula kunezinye iingqayi ze-Brita, kwaye isiciko sesandla esinye senza ukuphinda kube lula ngakumbi. Umqheba waso ogobileyo omile okwe-C ukhululekile ngakumbi kune-angular emile njenge-D efumaneka kwiibhotile ezininzi ze-Brita.
Isixhobo sokuhambisa amanzi saseBrita sigcina amanzi awoneleyo ngosuku kusapho olukhulu, kwaye impompo yaso engavuziyo ilula ngokwaneleyo ukuba abantwana bayisebenzise.
I-Brita Ultramax ehambisa amanzi ibamba malunga ne-27 yeekomityi zamanzi (iikomityi ezili-18 kwisisele sokuhluza kunye nezinye iikomityi ezili-9 okanye ezili-10 kwindawo yokugcina amanzi). Uyilo lwayo olubhityileyo lugcina indawo efrijini, kwaye impompo ivaleka ngokuzenzekelayo emva kokugalela ukuthintela ukuphuphuma. Le yindlela efanelekileyo yokuhlala unamanzi abandayo acocekileyo aneleyo.
I-LifeStraw Home Water Dispenser ivavanywa ngokuthembekileyo ukuze isuse ungcoliseko oluninzi, kuquka ilothe, kwaye isihluzo saso asithandeki kakhulu ekuvalelekeni kunaso nasiphi na esinye isixhobo esisivavanyileyo.
Siqhube iilitha ezi-2.5 zamanzi angcoliseke kakhulu ngumhlwa nge-LifeStraw yamanzi asekhaya, kwaye nangona amanzi ehlile kancinci ukuya esiphelweni, ukuhluzwa akuzange kume. Kwabo baye bafumana ii-clogs kwezinye izihluzi zamanzi (kubandakanywa ne-pick yethu ephezulu ye-Brita Elite) okanye bafuna isisombululo kumanzi ompompo anomhlwa okanye amdaka, esi sihluzo lukhetho lwethu olucacileyo. I-LifeStraw ineziqinisekiso ezine ze-ANSI/NSF (i-chlorine, i-taste kunye nevumba, i-lead kunye ne-mercury) kwaye ihlolwe ngokuzimeleyo yi-laboratory eqinisekisiweyo ukuhlangabezana nemigangatho emininzi yokutshatyalaliswa kwe-ANSI / NSF.
Izinto zokucoca i-Dexsorb zivavanywa kwimigangatho ye-NSF/ANSI kwaye ibambe ngokufanelekileyo uluhlu olubanzi lweekhemikhali eziqhubekayo (PFAS), kubandakanya iPFOA kunye nePFOS.
Izihluzi zeCyclopure Purefast zisebenzisa izinto ezifanayo zeDexsorb ezisetyenziswa kwezinye iindawo zokucocwa kwamanzi amdaka ukususa ngokusisigxina iikhemikhali (PFAS) kunikezelo lwamanzi lukawonkewonke. Ilingana neejagi zethu ezicetyiswayo zeBrita kunye nezixhobo zokukhupha iimpahla. Ilinganiswe kwiigaloni ezingama-65 kwaye izihluzo ngokukhawuleza kuvavanyo lwethu kwaye ayicothi kakhulu ekuhambeni kwexesha, nangona njengaso nasiphi na isihluzo somxhuzulane, ukuba kukho intlenga eninzi emanzini inokuvaleka. Isihluzi sikwaza nempahla ehlawulwa ngaphambili; thumela isihluzo esisetyenzisiweyo emva kwi-Cyclopure kwaye inkampani iya kuyiqhuba ukutshabalalisa nayiphi na i-PFAS ebanjiweyo ukuze ingasakwazi ukungena kwindawo. I-Brita ngokwayo ayikukhuthazi ukusetyenziswa kwezihluzi zeqela lesithathu, kodwa ngenxa yokuba zombini izihluzi zePurefast kunye nezixhobo ze-Dexsorb ziqinisekiswe yi-NSF/ANSI ukunciphisa iPFAS, siziva sizithembile ekuzincomeni. Qaphela ukuba ibamba kuphela iPFAS kunye neklorini. Ukuba unexhala ngezinye izinto, cinga ngeBrita Elite;
Ndiye ndivavanya izihluzi zamanzi ze-Wirecutter ukususela ngo-2016. Kwingxelo yam, ndathetha ixesha elide kunye ne-NSF kunye neZiko loMgangatho waManzi, imibutho emibini yezatifikethi zokucoca amanzi e-United States, ukuqonda ukuba uvavanyo lwabo luqhutywa njani. Ndikhe ndadlana indlebe nabameli abasuka kubenzi abaninzi bokucoca amanzi ukuze baphikise amabango abo. Ndisebenzise izihluzi ezininzi kunye neengqayi kule minyaka idlulileyo ngenxa yokuba ukuqina ngokubanzi, ukukhululeka kunye neendleko zokugcinwa, kunye nobuhlobo bomsebenzisi zibaluleke kakhulu kwinto oyisebenzisayo amaxesha amaninzi ngemini.
Owayesakuba ngusosayensi we-NOAA uJohn Holecek uphande kwaye wabhala inguqulelo yangaphambili yesi sikhokelo, wenza uvavanyo lwakhe, kwaye wagunyazisa uvavanyo oluzimeleyo.
Esi sikhokelo sesabo bafuna isihluzo samanzi se-pitcher esigcwalisa amanzi abo ompompo kwaye siyigcine kwisikhenkcisi sabo.
Inzuzo yesihluzi se-pitcher kukuba kulula ukuyisebenzisa. Konke okufuneka ukwenze kukuzigcwalisa kwimpompo kwaye ulinde ukuba isihluzo sisebenze. Zikwathanda ukuba kutshiphu ukuthenga, kunye nezihluzo ezitshintshiweyo (ezidla ngokufuneka rhoqo ngeenyanga ezimbini) zibiza ngaphantsi kwe $15.
Banezinto ezininzi ezingalunganga. Banokususa ngokufanelekileyo uluhlu oluncinci lwezinto ezingcolisayo kunezihluzo ezininzi ezingaphantsi kwe-sinki okanye ngaphantsi kwe-faucet kuba zixhomekeke kubunzima bomxhuzulane endaweni yoxinzelelo lwamanzi, zifuna isihluzo esixinene kancinci.
Ukuxhomekeka kubunzima bomxhuzulane kukwathetha ukuba izihluzi zepitcher ziyacotha: ukuzaliswa nje kwamanzi okukodwa ukusuka kwidama eliphezulu kunokuthatha imizuzu emi-5 ukuya kweli-15 ukudlula kwisihluzo, kwaye kaninzi kufuna ukongezwa okuninzi ukuze ufumane ingqayi epheleleyo yamanzi acocekileyo. .
Izihluzi zeJagi zihlala zixinga ngenxa yentlenga kumanzi etephu okanye amaqamza amancinane omoya asuka kwimibhobho yomoya.
Ngezi zizathu, sincoma ukufaka isihluzi phantsi kwe-sink okanye kwi-faucet ukuba iimeko ziyayifuna.
EUnited States, unikezelo lwamanzi lukawonke-wonke lulawulwa yi-Arhente yoKhuseleko lokuSingqongileyo (EPA) phantsi koMthetho waManzi okuSela ngokuKhuselekileyo, kwaye amaziko okucoca amanzi aphuma kuluntu kufuneka ahlangabezane nemigangatho engqongqo yobulunga. Nangona kunjalo, ayizizo zonke izinto ezinokuthi zingcolise izinto ezilawulwayo.
Ukongezelela, ukungcola kungangena emva kokuba amanzi eshiya isityalo sonyango ngemibhobho evuzayo okanye (kwimeko yelothe) ngokuvuza kwimibhobho ngokwayo. Ukucocwa kwamanzi okwenziweyo okanye ukungahoywa kwesi sityalo kunokwenza kube mandundu ukuvuza kwimibhobho esezantsi, njengoko kwenzeka eFlint, eMichigan.
Ukufumana kanye ukuba yintoni na ekumanzini omboneleli wakho, ungakhangela kwi-intanethi ye-EPA-evunyiweyo yeNgxelo yoMthengi yoMthengi (CCR). Kungenjalo, bonke ababoneleli bamanzi bakawonke-wonke kufuneka bakunike iiCCR zabo xa becelile.
Kodwa ngenxa yongcoliseko olunokwenzeka emazantsi omlambo, ekuphela kwendlela yokubona ukuba yintoni na emanzini endlu yakho kukuwavavanya. Ilabhoratri yomgangatho wamanzi yendawo yakho inokukwenza oku, okanye ungasebenzisa ikiti yokuvavanya ekhaya. Sijonge ezili-11 kubo kwisikhokelo sethu kwaye sachukumiseka linqaku leSimpleLab's Tap, ekulula ukulisebenzisa kwaye libonelela ngengxelo eneenkcukacha, ebhalwe ngokucacileyo ukuba yintoni, ukuba ikho, ungcoliseko lusemanzini akho etephu.
Uvavanyo lwamanzi lukamasipala lweSimpleLab Tap oluphambili lubonelela ngohlalutyo olubanzi lwamanzi akho okusela kwaye lubonelela ngeziphumo ekulula ukuzifunda.
Ukuqinisekisa ukuba sicebisa kuphela izihluzi onokuthi uzithembe, kudala sinyanzelisa ukuba ukhetho lwethu lufikelele umgangatho wegolide: isiqinisekiso se-ANSI/NSF. I-American National Standards Institute (ANSI) kunye neNational Science Foundation (NSF) yimibutho yabucala, engenzi nzuzo esebenza kunye ne-Arhente yoKhuseleko lokusiNgqongileyo, abavelisi kunye nezinye iingcali ukuphuhlisa imigangatho yomgangatho ongqongqo kunye nokuvavanya amawaka eemveliso, kuquka iiprothokholi zamanzi. isihluzo.
Kuphela kwaba semva kokusebenzisa iisampulu “zovavanyo”, ezazingcoliseke kakhulu kunamanzi ompompo omninzi, apho izihluzi zikwazile ukuhlangabezana nemigangatho yoqinisekiso, zigqithise kakhulu ubomi bazo obulindelekileyo.
Iilabhoratri ezimbini eziphambili zokuqinisekisa isihluzo samanzi yiNSF ngokwayo kunye noMbutho woMgangatho waManzi (WQA). Bobabini bavunywe ngokupheleleyo yi-ANSI kunye neBhunga leMigangatho yaseKhanada eNyakatho Melika kwaye banokwenza uvavanyo lwe-ANSI / NSF yokuqinisekisa.
Kodwa emva kweminyaka yeengxoxo zangaphakathi, ngoku sikwamkele ulwimi olukhululekileyo "luvavanywa kwimigangatho ye-ANSI / NSF" kunokuba sifumane isatifikethi esisemthethweni, ngokuxhomekeke kwiimeko ezimbalwa ezingqongqo: Okokuqala, uvavanyo lwenziwa ilabhoratri ezimeleyo, kungekhona ngokuzimela. ilabhoratri. umenzi wesihluzi; okwesibini, i-laboratory ngokwayo ivunyiwe yi-ANSI okanye enye imibutho yesizwe okanye engekho phantsi kukarhulumente ukuba iqhube uvavanyo olungqongqo ngokwemigangatho emiselweyo; okwesithathu, umenzi uchaza ulwazi malunga nebhubhoratri yokuvavanya, iziphumo zayo kunye neendlela; Umenzi unamava amaninzi okwenza izihluzi eziye zabonisa ukuba zikhuselekile, zithembekile kwaye zichazwe ngokunyanisekileyo.
Siphinde sayicutha phantsi kwizihluzi eziqinisekisiweyo okanye ezilingana ubuncinane nemigangatho emibini ye-ANSI/NSF (uMgangatho wama-42 kunye noMgangatho wama-53) (ukugquma i-chlorine kunye nezinye izinto ezingcolisayo "zobuhle" kunye neentsimbi ezinzima ezifana nelothe, ngokulandelelana) ngokunjalo. njengezibulali-zinambuzane. kunye nezinye iikhompawundi eziphilayo). Umgangatho omtsha we-401 uquka "ungcoliseko olusakhulayo," olufana namayeza, afumaneka ngakumbi emanzini e-United States, yingakho sinikela ingqalelo ekhethekileyo kwizihluzi.
Siqale ukukhangela iiketile ezidumileyo ezikwi-10 ukuya kwi-11 zekomityi ezinomthamo kunye nezixhobo ezinkulu zokukhupha amanzi, eziluncedo kakhulu kumakhaya asebenzisa amanzi kakhulu. (Iinkampani ezininzi zibonelela ngeengqayi ezincinci kwabo bangayidingi imodeli epheleleyo.)
Emva koko sithelekisa iinkcukacha zoyilo (kubandakanywa nesitayile sokubamba kunye nokuthuthuzela), ukukhululeka kofakelo lokucoca kunye nokutshintshwa, indawo i-pitcher kunye ne-dispenser ithatha kwifriji, kunye nomlinganiselo wevolumu yetanki ephezulu yokuzalisa ukuya kwi-tank "yesihluzi". (Okukhona uphezulu umlinganiselo, kungcono, kuba uya kufumana amanzi ahluziweyo ngakumbi ngalo lonke ixesha usebenzisa impompo.)
Senze iimvavanyo ezininzi kwizihluzi ezininzi ngo-2016, sithelekisa iziphumo zethu neziqinisekiso ze-ANSI/NSF kunye namabango omenzi. Kwilebhu yakhe, uJohn Holecek walinganisa umlinganiselo isihluzo ngasinye esisuse ngaso iklorin. Kwiinketho zethu ezimbini zokuqala, senze ikhontrakthi yovavanyo lokususa isikhokelo esizimeleyo sisebenzisa izisombululo zongcoliseko olukhokelayo ngaphezu kokuba i-NSF ifuna kwisivumelwano sayo soqinisekiso.
Eyona nto siyithathayo kuvavanyo lwethu kukuba isatifikethi se-ANSI/NSF okanye isatifikethi esilinganayo sisilathisi esithembekileyo sokusebenza kohluzo. Oku akumangalisi xa kunikwe ubume obungqongqo bemigangatho yoqinisekiso. Ukusukela ngoko, siye sathembela kwisatifikethi se-ANSI/NSF okanye isiqinisekiso esilinganayo ukumisela ukusebenza kwesihluzo esinikiweyo.
Uvavanyo lwethu olulandelayo lujolise kusetyenziso lwehlabathi lokwenyani, kunye neempawu ezisebenzayo kunye neziphene ezithi zibonakale xa uqala ukusebenzisa iimveliso ngokuhamba kwexesha.
Lo mzekelo unezitifiketi ezingaphezu kwe-30 ze-ANSI / NSF-ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo-kwaye yenzelwe ukuhlala iinyanga ezintandathu phakathi kokutshintshwa. Kodwa, njengazo zonke izihluzi, inokuvalwa.
I-Brita Elite (eyayifudula i-Longlast +) izihluzi zi-ANSI/NSF eziqinisekisiweyo zokubona ngaphezulu kwe-30 engcolisekileyo (PDF), kubandakanya 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 kuyenza ibe sesona sihluzo siqinisekisiweyo esisivavanyileyo, kwaye enye esiyicebisayo kwabo bafuna uxolo lwengqondo olukhulu.
Kungqinwe ukuba kususwe amanye amabala amaninzi aqhelekileyo. Ezi ziquka iklorini (eyongezwa emanzini ukunciphisa ibhaktheriya kunye nezinye iintsholongwane kwaye ngoyena nobangela wokungcamla kakubi kwamanzi empompo); i-carbon tetrachloride, i-volatile organic compound eyonakalisa isibindi kwaye ifumaneka ngokunyuka kumanzi; "Iikhompawundi ezintsha" zafunyanwa, kuquka i-bisphenol A (BPA), i-DEET (i-insect repellent eqhelekileyo) kunye ne-estrone (i-synthetic form of estrogen).
Ngelixa uninzi lwezihluzi zepitcher zinomjikelo wokutshintsha zonke iilitha ezingama-40 okanye iinyanga ezimbini, i-Elite inomjikelo wokutshintsha we-120 yeegaloni okanye iinyanga ezintandathu. Ngokwethiyori, oku kuthetha ukuba kufuneka usebenzise kuphela izihluzo ezimbini ze-Elite ngonyaka endaweni yesithandathu, udala inkunkuma encinci kunye nokunciphisa iindleko zokuzalisa kwakhona malunga ne-50%.
Kwi-pitcher filter, isebenza ngokukhawuleza. Kuvavanyo lwethu, isihluzi esitsha se-Elite sithathe nje imizuzu emihlanu ukuya kwesixhenxe ukugcwalisa. Izihluzo ezilinganayo esizivavanyileyo zithatha ixesha elide-ngemizuzu eyi-10 nangaphezulu.
Kodwa kukho i-caveat. Njengazo zonke izihluzi zepitcher, i-Elite inokuxinana ngokulula, enokuthi ithobe isantya sayo sokuhluza okanye ide iyithintele ekuhluzeni ngokupheleleyo, okuthetha ukuba kuya kufuneka uyibuyisele rhoqo. Abaninzi, abanini abaninzi baye bakhalaza ngalo mbandela, kwaye kuvavanyo lwethu, i-Elite yaqala ukumisa ngaphambi kokufikelela kumthamo wayo we-120-gallon. Ukuba unengxaki eyaziwayo ngentlenga kumanzi etephu yakho (ehlala iluphawu lwemibhobho erusi), amava akho aya kuba njalo.
Kwaye usenokungadingi lonke ukhuseleko lwabaphezulu. Ukuba uyazi ukuba amanzi akho etephu asemgangathweni olungileyo (oku kunokumiselwa kusetyenziswa umvavanyi wasekhaya), sicebisa ukuba usebenzise isiseko sembiza ye-Brita yokukhupha amanzi kunye nesihluzi. Ineziqinisekiso ezihlanu ze-ANSI / NSF kuphela (i-PDF), kubandakanywa i-chlorine (kodwa ingekho i-lead, i-organics, okanye i-contaminants emitsha), ekude kakhulu kwinqanaba le-certification yokuba i-Elite inakho. Kodwa sisihluzo esinexabiso eliphantsi, esisivalekileyo esinokuphucula incasa yamanzi akho.
