Siyaqinisekisa ngokuzimeleyo yonke into esiyicebisayo. Xa uthenga ngeekhonkco zethu, sinokufumana ikhomishini. funda ngakumbi>
UTim Heffernan ngumbhali ogubungela umoya kunye nomgangatho wamanzi kunye nobuchwepheshe bamandla obuzinzileyo. Ukhetha ukuvavanya abacoci ngomsi wemidlalo yeFlare.
Siphinde songeze inketho enkulu, iCyclopure Purefast, isihluzi esihambelana neBrita ene-NSF/ANSI eqinisekisiweyo ukunciphisa iPFAS.
Ukuba ujonge eyona ndlela ilula yokufumana amanzi okusela ahluziweyo ekhaya, sicebisa isihluzo saManzi se-Brita Elite, kunye neMigangatho ye-Brita yeMihla yonke ye-10-Cup Pitcher okanye (ukuba usebenzisa amanzi amaninzi ekhayeni lakho) Umgangatho we-Brita oMgangatho wama-27-indebe yokuCapacity Pitcher okanye i-Brita Ultramax Water Dispenser. Kodwa ngaphambi kokuba ukhethe nokuba yeyiphi na, yazi ukuba emva kweshumi leminyaka lokuphumeza ukuhluzwa kwamanzi asekhaya, sikholelwa ukuba izihluzi zamanzi angaphantsi kwe-sinki okanye ngaphantsi kwe-faucet lolona khetho lulungileyo. Zihlala ixesha elide, zihambisa amanzi acocekileyo ngokukhawuleza, zinciphisa ungcoliseko, azifane zivale, kwaye zithatha nje imizuzu embalwa ukuzifaka.
Le modeli inezatifikethi ezingaphezu kwama-30 ze-ANSI/NSF, ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo, kwaye yenzelwe isithuba sokutshintshwa kweenyanga ezintandathu. Kodwa njengazo zonke izihluzi, zinokuvaleka.
Iketile yotyikityo lweBrita ngeendlela ezininzi ludidi lweketile yokucoca kwaye kulula ukuyisebenzisa nokuyigcina icocekile kunezinye iimodeli ezininzi zeBrita.
I-Brita Water Dispenser inamandla aneleyo okuhlangabezana neemfuno zamanzi zemihla ngemihla zentsapho enkulu, kwaye i-faucet yayo engavuziyo yenzelwe ukuba ibe lula kwaye ilula ukuba abantwana bayisebenzise.
I-LifeStraw Home Dispenser ivavanyiwe ngokungqongqo ukuba isuse ungcoliseko oluninzi, kuquka nelothe, kwaye isihluzo sayo sixhathisa kakhulu ekuvalelekeni kunaso nasiphi na esinye isihluzi esisivavanyileyo.
Izinto zokucoca i-Dexsorb, ezivavanyiweyo kwimigangatho ye-NSF/ANSI, ibamba ngokufanelekileyo uluhlu olubanzi lwezinto eziqhubekayo zeekhemikhali (PFAS), kubandakanya iPFOA kunye nePFOS.
Le modeli inezatifikethi ezingaphezu kwama-30 ze-ANSI/NSF, ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo, kwaye yenzelwe isithuba sokutshintshwa kweenyanga ezintandathu. Kodwa njengazo zonke izihluzi, zinokuvaleka.
Esona sihluzo sikaBrita sisebenza kakuhle yiBrita Elite. Yi-ANSI/NSF eqinisekisiweyo kwaye isusa ungcoliseko olungakumbi kunaso nasiphi na esinye isihluzo samanzi esondliwa ngumxhuzulane esikhe savavanya; ezi zingcolisi ziquka ilothe, i-mercury, i-cadmium, i-PFOA, kunye ne-PFOS, kunye noluhlu olubanzi lweekhompawundi zemizi-mveliso kunye nongcoliseko lwamanzi ompompo oluya lusiba "lungcoliseko olusakhulayo." Inobomi obuziigaloni ezili-120, okanye iinyanga ezintandathu, nto leyo ephinda-phinda kathathu ubude bobomi obulinganiselweyo kwezinye izihluzi. Ekuhambeni kwexesha, loo nto yenza ukuba i-Elite ingabizi kakhulu kuneyona ndlela iqhelekileyo yokucoca iinyanga ezimbini. Nangona kunjalo, intlenga emanzini inokuyivala phambi kokuba iinyanga ezintandathu ziphele. Ukuba uyazi ukuba amanzi akho etephu acocekile kodwa ufuna nje ukuba anencasa ngcono (ingakumbi ukuba inuka njengeklorini), iketile esemgangathweni yeBrita kunye nesihluzi se-dispenser ayibizi kakhulu kwaye ayifuni ukuvaleka, kodwa ayiqinisekiswanga ukuba iqulathe ilothe okanye nayiphi na enye imizi-mveliso. iikhompawundi.
Iketile yotyikityo lweBrita ngeendlela ezininzi ludidi lweketile yokucoca kwaye kulula ukuyisebenzisa nokuyigcina icocekile kunezinye iimodeli ezininzi zeBrita.
Kuninzi lweengqayi zeBrita, esizithandayo yiBrita esemgangathweni yemihla ngemihla ye-10-Cup Pitcher. Uyilo lwendawo engafanga lwenza kube lula ukucoca kunezinye iibhotile zeBrita, kwaye isiciko sesandla esinye sokuguqula ubhontsi senza ukuphinda kugcwaliswe kube lula. Umqheba waso ogobileyo omile okwe-C ukhululekile ngakumbi kuneziphatho ezimile okwe-angular ezifumaneka kwiibhotile ezininzi zeBrita.
I-Brita Water Dispenser inamandla aneleyo okuhlangabezana neemfuno zamanzi zemihla ngemihla zentsapho enkulu, kwaye i-faucet yayo engavuziyo yenzelwe ukuba ibe lula kwaye ilula ukuba abantwana bayisebenzise.
I-Brita Ultramax Water Dispenser ibamba malunga ne-27 yeekomityi zamanzi (iikomityi ezili-18 kwisisele sokuhluza kunye ne-9 ukuya kwi-10 yeekomityi ezongezelelweyo kwindawo yokugcwalisa engaphezulu). Uyilo lwayo olubhityileyo lugcina indawo efrijini, kwaye itephu iyavaleka emva kokugalela ukunqanda ukuphuphuma. Yindlela efanelekileyo yokuhlala unamanzi amaninzi abandayo, ahluziweyo esandleni.
I-LifeStraw Home Dispenser ivavanyiwe ngokungqongqo ukuba isuse ungcoliseko oluninzi, kuquka nelothe, kwaye isihluzo sayo sixhathisa kakhulu ekuvalelekeni kunaso nasiphi na esinye isihluzi esisivavanyileyo.
Sasebenzisa i-LifeStraw Home Water Dispenser ukucoca iilitha ezingama-2.5 zamanzi amdaka kakhulu, kwaye ngelixa isantya sancipha kancinci ukuya esiphelweni, asizange siyeke ukucoca. Le mveliso yeyona iphambili yokukhetha kuye nabani na okhe wafumana izihluzi zamanzi ezivalekileyo kwezinye izihluzi zamanzi, kubandakanya ukukhetha kwethu okuphezulu, i-Brita Elite, okanye ijonge isisombululo kumanzi ompompo anomhlwa okanye angcolisekileyo. I-LifeStraw ineziqinisekiso ezine ze-ANSI / NSF (i-chlorine, i-taste kunye ne-odor, i-lead, kunye ne-mercury) kwaye ihlolwe ngokuzimeleyo ngelebhu eqinisekisiweyo ukuhlangabezana nemigangatho eyongezelelweyo yokucoca i-ANSI / NSF.
Izinto zokucoca i-Dexsorb, ezivavanyiweyo kwimigangatho ye-NSF/ANSI, ibamba ngokufanelekileyo uluhlu olubanzi lwezinto eziqhubekayo zeekhemikhali (PFAS), kubandakanya iPFOA kunye nePFOS.
Izihluzi zeCyclopure's Purefast zisebenzisa iDexsorb, izinto ezifanayo ezisetyenziswa zezinye izityalo zonyango ukususa imichiza eqhubekayo (PFAS) kunikezelo lwamanzi lukawonkewonke. Isebenza ngeketile yethu yeBrita ecetyiswayo kunye ne-dispenser. Ithelekelwe iilitha ezingama-65, izihluzi ngokukhawuleza kuvavanyo lwethu, kwaye ayicothi kakhulu ekuhambeni kwexesha, nangona njengaso nasiphi na isihluzo esondliwe ngumxhuzulane, inokuvala ukuba amanzi akho anentlenga eninzi. Isihluzi sifika kwimvulophu ehlawulelwe kwangaphambili; thumela isihluzo sakho esisetyenzisiweyo kwi-Cyclopure, kwaye inkampani iya kuyisebenzisa kwakhona ngendlela etshabalalisa nayiphi na i-PFAS eyibambayo ukuze ingavuzi ibuyele kokusingqongileyo. I-Brita ngokwayo ayicebisi izihluzi zeqela lesithathu, kodwa ngenxa yokuba zombini izihluzi zePurefast kunye nezixhobo zeDexsorb ziyi-NSF/ANSI eqinisekisiweyo ukunciphisa iPFAS, singabacebisa ngokuzithemba. Qaphela ukuba ibamba kuphela iPFAS kunye neklorine. Ukuba unezinye izinto ezikuxhalabisayo, khetha iBrita Elite;
Ndiye ndavavanya izihluzi zamanzi kwi-Wirecutter ukususela ngo-2016. Kwingxelo, ndibe neengxoxo ezinde kunye ne-NSF kunye noMbutho woMgangatho waManzi, ii-arhente ezimbini ezinkulu zokuqinisekisa isihluzo samanzi e-United States, ukuqonda iindlela zabo zokuvavanya. Ndiye ndadliwano-ndlebe nabameli abasuka kubenzi abaninzi bokucoca amanzi ukuze baqinisekise amabango abo. Ndisebenzise izihluzi zamanzi ezininzi kunye neengqayi kule minyaka idlulileyo ngenxa yokuba ukuqina ngokubanzi, ukukhululeka kunye neendleko zokugcina, kunye nokusebenziseka ngokulula kubalulekile kwinto esetyenziswa amaxesha amaninzi ngemini.
Owayesakuba yi-National Oceanic and Atmospheric Administration (NOAA) usosayensi uJohn Holecek wenze uphando kwaye wabhala inguqulelo yangaphambili yesi sikhokelo, wenza uvavanyo lwakhe, kwaye wagunyazisa uvavanyo oluzimeleyo.
Esi sikhokelo sesabo bafuna isihluzo samanzi sohlobo lweketile (leyo iqokelela amanzi etephini ize iwagcine efrijini).
Ubuhle beketile yokucoca kukuba kulula ukuyisebenzisa. Uyigcwalise ngokulula ngamanzi epompo kwaye ulinde ukuba isihluzo sisebenze. Ngokuqhelekileyo azibizi: izihluzi ezitshintshiweyo (ekufuneka zitshintshwe qho kwiinyanga ezimbini) zibiza ngaphantsi kwe-$15.
Baneengxaki ezimbalwa. Ziyasebenza ngokuchasene nezingcolisi ezimbalwa kunezihluzo ezininzi ezingaphantsi kwe-sinki okanye ngaphantsi kwe-faucet kuba zixhomekeke kubunzima bomxhuzulane endaweni yoxinzelelo lwamanzi, zifuna isihluzo esisezantsi soxinaniso.
Ukusebenzisa umxhuzulane kukwathetha ukuba izihluzi zeketile ziyacotha: ukuzalisa amanzi kwidama elingaphezulu kuthatha phakathi kwemizuzu emi-5 kunye ne-15 ukudlula kwisihluzo, kwaye kaninzi kuthatha ukuphinda kugcwaliswe kaninzi ukufumana ijagi epheleleyo yamanzi acocekileyo.
Izihluzi zeketile zihlala zivaleka yintlenga ephuma kumanzi etephu okanye amaqamza omoya amancinane athi akheke kwimibhobho ekhupha umoya aze avaleleke.
Ngezi zizathu, sincoma ukufaka isihluzi phantsi kwe-sink okanye kwi-faucet ukuba iimeko zivuma.
EUnited States, unikezelo lwamanzi lukawonke-wonke lulawulwa yi-Arhente yoKhuseleko lweNdalo (EPA) phantsi koMthetho waManzi okuSela ngokuKhuselekileyo, kwaye amanzi akhutshwa kwiindawo zokucocwa kwamanzi karhulumente kufuneka ahlangabezane nemigangatho engqongqo yobulunga. Nangona kunjalo, ayizizo zonke izinto ezinokuthi zingcoliseke zilawulwa.
Ukongezelela, ukungcola kungangena emva kokuba amanzi eshiya amaziko onyango ngokusebenzisa imibhobho evuzayo okanye (kwimeko yelothe) ngokukhupha kwimibhobho ngokwayo. Ukunyanga amanzi kwisityalo (okanye ukusilela ukwenza njalo) kunokwenza ukuvuza kwimibhobho esezantsi kube mandundu, njengoko kwenzekileyo eFlint, eMichigan.
Ukufumanisa ukuba umthengisi wakho ushiya ntoni na, usenokufumana i-EPA Consumer Confidence Report (CCR) enyanzelekileyo yomboneleli wakho wengingqi kwi-intanethi. Kungenjalo, bonke ababoneleli ngamanzi kuluntu kufuneka babonelele ngeCCR xa becelile.
Kodwa ngenxa yongcoliseko olunokwenzeka emazantsi omlambo, ekuphela kwendlela yokwazi ngokuqinisekileyo ukuba yintoni na esemanzini endlu yakho kukuba avavanywe. Ilebhu yengingqi yakho yomgangatho wamanzi inokuvavanya, okanye ungasebenzisa ikiti yovavanyo lwasekhaya. Sivavanye ezili-11 kuzo kwaye sachukumiseka linqaku leTap leSimpleLab, ekulula ukulisebenzisa kwaye libonelela ngengxelo ebanzi, ecacileyo yokuba loluphi ungcoliso, ukuba lukhona, lusemanzini akho etephu.
I-SimpleLab Tap Score uvavanyo lomgangatho wamanzi esixeko lubonelela ngohlalutyo olubanzi lwamanzi akho okusela kunye neziphumo ekulula ukuzifunda.
Ukuqinisekisa ukuba izihluzi zamanzi esizicebisayo zithembekile, sihlala sigxininisa ukuba ukhetho lwethu luhlangabezane nomgangatho 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 engqongqo yomgangatho wamawaka eemveliso, kubandakanya izihluzi zamanzi, kunye novavanyo. iinkqubo.
Izihluzi zihlangabezana kuphela nemigangatho yesiqinisekiso emva kokugqithisa ubomi bazo benkonzo obulindelekileyo kunye nokusebenzisa iisampuli "zovavanyo" ezingcoliseke kakhulu kunamanzi amaninzi etephu.
Kukho iilebhu ezimbini eziphambili eziqinisekisa izicoci zamanzi: enye yi-NSF Labs kwaye enye yiMbutho woMgangatho waManzi (WQA). Yomibini imibutho ivunywe ngokupheleleyo yi-ANSI kunye neBhunga leMigangatho yaseKhanada eNyakatho Melika ukwenza uvavanyo lwe-ANSI / NSF yokuqinisekisa.
Kodwa emva kweminyaka yengxoxo-mpikiswano yangaphakathi, ngoku sikwamkele ibango elibanzi "elivavanyiweyo kwimigangatho ye-ANSI/NSF," elingaqinisekiswanga ngokusemthethweni, kodwa kufuneka lihlangabezane neemeko ezithile ezingqongqo: okokuqala, uvavanyo lwenziwa ilebhu ezimeleyo engasebenziyo. umenzi wesihluzi; okwesibini, ilebhu ngokwayo i-ANSI okanye yamkelwa ngamanye amaqumrhu kazwelonke okanye angekho phantsi kukarhulumente ukwenza uvavanyo olungqongqo ngokwemigangatho esekiweyo; okwesithathu, ilebhu yovavanyo, iziphumo zayo, kunye neendlela zayo zipapashwa ngumvelisi. Okwesine, umenzi unembali ende yokuvelisa izihlungi. Iirekhodi zingqineke zikhuselekile, zithembekile, kwaye ziyinyani njengoko kuchaziwe.
Siphinde sanciphisa umda kwizihluzi eziqinisekisiweyo okanye ezilingana ubuncinane nemigangatho emibini emikhulu ye-ANSI/NSF (uMgangatho wama-42 kunye noMgangatho wama-53, ogubungela i-chlorine kunye nezinye izinto ezingcolisayo "zobuhle", kunye neentsimbi ezinzima njengelothe kunye ne-organic compounds njenge-pesticides. ). Umgangatho omtsha we-401 uquka "ungcoliseko olusakhulayo" olufana namayeza asanda kubakho emanzini ase-US, kwaye sihlawula ingqalelo ekhethekileyo kwizihluzi ezilo mahluko.
Siqale ngokujonga kwi-10- ukuya kwi-11-indebe zamanzi ezithandwayo, kunye nezixhobo ezinkulu zokukhupha amanzi ezifanelekileyo ngokukodwa kumakhaya asebenzisa amanzi amaninzi. (Uninzi lweenkampani zibonelela ngee-dispensers ezincinci kubantu abangayifuniyo i-dispenser epheleleyo.)
Emva koko siye sathelekisa iinkcukacha zoyilo (kubandakanya isimbo sokuphatha kunye nokuthuthuzela), ukulula kokufakela kunye nokutshintshwa kwesihluzi, indawo i-pitcher kunye ne-dispenser ezithatha efrijini, kunye nomthamo wetanki yokuzalisa ephezulu ngokuchasene nomlinganiselo wetanki "ehluziweyo". (okukhona uphezulu umlinganiselo, ngcono, kuba uya kufumana amanzi ahluziweyo ngakumbi ngalo lonke ixesha usebenzisa itephu).
Ngo-2016, siye saqhuba iimvavanyo ezininzi zangaphakathi zeefilitha ezininzi ukuthelekisa iziphumo zethu kunye nezatifikethi ze-ANSI/NSF kunye namabango omenzi. UJohn Holecek walinganisa isihluzo ngasinye sokususa iklorin kwilebhu yakhe. Kwiinketho zethu ezimbini zokuqala, siye sagunyazisa ilebhu yovavanyo ezimeleyo ukuba ivavanye ukususwa kwesikhokelo kusetyenziswa izisombululo ezinamaqondo aphezulu kakhulu osulelo lwelothe kunokuba i-NSF ifuna kwiprothokholi yoqinisekiso.
Isigqibo sethu esiphambili kuvavanyo lwethu kukuba isatifikethi se-ANSI/NSF okanye isatifikethi esilinganayo ngumgangatho othembekileyo wokulinganisa ukusebenza kwesihluzi. Oku akumangalisi xa kujongwa uhlobo olungqongqo lwemigangatho yoqinisekiso. Ukusukela ngoko, siye sathembela kwisatifikethi se-ANSI/NSF okanye isiqinisekiso esilinganayo ukumisela ukusebenza kwesihluzo esinikiweyo.
Uvavanyo lwethu olulandelayo lugxile kusetyenziso lwehlabathi lokwenyani, kunye neempawu zehlabathi lokwenyani kunye neziphene ezithi zibonakale emva kokusebenzisa ezi mveliso ixesha elide.
Le modeli inezatifikethi ezingaphezu kwama-30 ze-ANSI/NSF, ngaphezu kwaso nasiphi na isihluzi kwiklasi yayo, kwaye yenzelwe isithuba sokutshintshwa kweenyanga ezintandathu. Kodwa njengazo zonke izihluzi, zinokuvaleka.
Isihluzi saManzi se-Brita Elite (eyayisakuba yi-Longlast +) yi-ANSI/NSF eqinisekisiweyo yokususa 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). ). Loo nto iyenza ibe sesona sihluzo siphezulu samanzi esisivavanyileyo, kwaye enye esiyicebisayo kwabo bafuna olona xolo lwengqondo lokugqibela.
Iqinisekisiwe ukuba isuse ezinye izinto ezingcolileyo eziqhelekileyo. Ezi ngcoliseko ziquka i-chlorine (eyongeziweyo emanzini ukunciphisa iibhaktheriya kunye nezinye iintsholongwane, eyona nto ibangela "incasa embi" kumanzi ompompo), i-volatile organic compounds engonakalisa isibindi, kunye neentlobo "ezikhulayo" ezikhulayo; iikhompawundi ezifana ne-bisphenol A (BPA), iDEET (isixhobo esixhaphakileyo sokugxotha izinambuzane), kunye ne-estrone, uhlobo lokwenziwa lwe-estrogen, luyafunyanwa.
Ngelixa uninzi lwee-pitchers zineefilitha zamanzi ezifuna ukutshintshwa rhoqo kwiilitha ezingama-40 okanye iinyanga ezimbini, isihluzo samanzi se-Elite sithatha iilitha ezingama-120 okanye iinyanga ezintandathu. Ngokwethiyori, oko kuthetha ukuba kufuneka usebenzise kuphela izihluzi zamanzi ezimbini ze-Elite ngonyaka endaweni yesithandathu - ukudala inkunkuma encinci kunye nokunciphisa iindleko zokubuyisela malunga ne-50%.
Kwisihluzi se-pitcher, sisebenza ngokukhawuleza okukhulu. Kwiimvavanyo zethu, ukuzaliswa okupheleleyo kwesihluzo esitsha se-Elite kuthathe imizuzu emi-5-7 kuphela. Izihluzo ezinobungakanani obufanayo esizivavanyileyo zithatha ixesha elide — rhoqo imizuzu eli-10 nangaphezulu.
Kodwa kukho ingxaki. Njengazo zonke izihluzi zepitcher, i-Elite ithanda ukuvaleka, enokucothisa okanye imise ukuhluzwa kwayo, okuthetha ukuba kuya kufuneka uyibuyisele rhoqo. Abasebenzisi abaninzi baye bakhalaza ngalo mbandela, kwaye kuvavanyo lwethu, i-Elite yaqala ukucotha ngaphambi kokuba ifikelele kumthamo wayo we-120-gallon. Ukuba unengxaki ngentlenga kumanzi etephu yakho (ehlala iluphawu lwemibhobho erusi), unokuba unengxaki efanayo.
Kwaye unokungadingi lonke ukhuseleko lwe-Elite. Ukuba uqinisekile ukuba amanzi etephu akho asemgangathweni olungileyo (ungatsho ngomvavanyi wasekhaya), sicebisa ukuba uphucule ukuya kwiketile esisiseko yeBrita kunye nesihluzi samanzi. Ineziqinisekiso ezihlanu ze-ANSI/NSF (PDF), kubandakanywa neklorini (kodwa ingakhokelelanga, i-organics, okanye i-contaminants ephumayo), engaphantsi kakhulu kune-Elite. Kodwa sisihluzo esinexabiso eliphantsi, esisivalekileyo esinokuphucula incasa yamanzi akho.
Kulula ukuyijija xa ufaka isihluzo seBrita. Ekuqaleni, isihluzi sabonakala singena endaweni ngokukhuselekileyo ngokwaneleyo. Kodwa eneneni ithatha utyhala olongezelelweyo ukuyingenisa yonke indlela. Ukuba awuwatyhali ezantsi, amanzi angahluzwanga anokuvuza amacala esihluzi xa ugcwalisa indawo yokugcina amanzi, okuthetha ukuthi amanzi akho “ahluziweyo” akasayi kuphumelela. phuma. Ezinye izihluzi esizithengele uvavanyo luka-2023 nazo bezifuna ukubekwa ukuze indawo ende kwelinye icala lesihluzi ityibilike phezu komqolo ohambelanayo kwezinye iipakethi zeBrita. (Ezinye iibhotile, kubandakanywa neyona bhotile yethu yamanzi ye-10-ikomityi yemihla ngemihla, ayinayo imiqolo, ekuvumela ukuba ubeke isihluzo nangayiphi na indlela.)
