I-Wirecutter ixhasa abafundi. Xa uthenga ngekhonkco elikwiwebhusayithi yethu, sinokufumana ikhomishini yokubambisana. Funda ngakumbi
Sikwakhethe i-Aquasana Claryum Direct Connect kakuhle - kulula ukuyifaka kwaye inokubonelela ngamanzi amaninzi kwiimpompo ezikhoyo.
Nabani na osela amanzi angaphezu kweelitha ezimbalwa ngosuku angathanda ukusebenzisa inkqubo yokucoca amanzi engaphantsi kwetanki efana ne-Aquasana AQ-5200. Ukuba ukhetha (okanye ufuna) amanzi ahluziweyo, angafumaneka rhoqo kwimpompo eyahlukileyo njengoko kufuneka. Sicebisa i-Aquasana AQ-5200 kuba isiqinisekiso sayo sesona silungileyo kuzo zonke iinkqubo esizifumeneyo.
I-Aquasana AQ-5200 ifumene isiqinisekiso esinobungcolisi obuninzi, ifumaneka ngokubanzi, ixabiso layo lifikeleleka, kwaye inesakhiwo esincinci. Yinkqubo yokuqala yokucoca amanzi engaphantsi kwetanki esiyikhangelayo.
I-Aquasana AQ-5200 iphumelele isiqinisekiso se-ANSI/NSF kwaye inokususa phantse ii-77 ezahlukeneyo zongcoliseko, kubandakanya i-lead, i-mercury, ii-volatible organic compounds, iziyobisi, kunye nezinye izinto ezingafane zibanjwe ngabakhuphisana nabo. Yenye yezihluzi ezimbalwa kakhulu eziqinisekisiweyo ze-PFOA kunye ne-PFOS. Ezi compounds zibandakanyeka ekwenziweni kwezinto ezinganamatheliyo kwaye zafumana ingcebiso yezempilo ye-EPA ngoFebruwari 2019.
Ixabiso lokutshintsha iseti yezihluzo limalunga ne-US$60, okanye ixesha lokutshintsha leenyanga ezintandathu elicetyiswa yi-Aquasana liyi-US$120 ngonyaka. Ngaphezu koko, le nkqubo inkulu kuneekotoni ezimbalwa zesoda kwaye ayithathi ndawo ininzi exabisekileyo phantsi kwesinki. Le nkqubo isetyenziswa kakhulu isebenzisa izixhobo zesinyithi ezikumgangatho ophezulu, kwaye iimpompo zayo ziza ngeendlela ezahlukeneyo zokugqiba.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 ngokweziqinisekiso, iinkcukacha kunye nobukhulu. Yahlukile kwiLowe's kwaye ngenxa yoko ayifumaneki lula kangako.
I-AO Smith I-AO-US-200 ifana ne-Aquasana AQ-5200 kuzo zonke iinkalo ezibalulekileyo. (Oku kungenxa yokuba i-AO Smith yafumana i-Aquasana ngo-2016.) Inesatifikethi esifanayo esihle, izixhobo zesinyithi zonke, kunye ne-compact form factor, kodwa ngenxa yokuba ithengiswa kuphela kwaLowe's, uluhlu lwayo lokuthengisa alubanzi, kwaye i-faucet yayo. Kukho ukugqitywa okukodwa kuphela: i-nickel ebhrashiweyo. Ukuba oku kuhambelana nesitayile sakho, sicebisa ukuba uthenge phakathi kweemodeli ezimbini ngexabiso: enye okanye enye ihlala inesaphulelo. Iindleko zokutshintsha isihluzi ziyafana: malunga ne-$60 kwiseti, okanye i-$120 ngonyaka kumjikelo weenyanga ezintandathu ocetyiswe yi-AO Smith.
I-AQ-5300+ inesiqinisekiso esifanayo esibalaseleyo, kodwa ngenxa yesantya sokuhamba kwamanzi esiphezulu kunye nomthamo wokucoca, ifanelekile kumakhaya asebenzisa amanzi amaninzi, kodwa ixabiso liphezulu kwaye ithatha indawo engaphezulu phantsi kwesinki.
I-Aquasana AQ-5300+ maximum flow ineziqinisekiso ze-ANSI/NSF ezingama-77 ezifanayo nezinye iimveliso zethu esizithandayo, kodwa inika ukuhamba okuphezulu (iigaloni ezingama-0.72 kunye ne-0.5 ngomzuzu) kunye nomthamo wesihluzo (iigaloni ezingama-800 kunye ne-500). Oku kwenza kube lolona khetho lokuqala kwiintsapho ezifuna amanzi amaninzi ahluziweyo kwaye zifuna ukuwasebenzisa ngokukhawuleza. Ikwadibanisa isihluzo sangaphambi kwesisele, esingafumanekiyo kwi-AQ-5200; oku kunokwandisa izinga eliphezulu lokuhamba kwesihluzo sokungcola kwimizi etyebileyo ngamanzi esisele. Ngamanye amazwi, imodeli ye-AQ-5300+ (exhotyiswe ngesihluzo sebhotile seelitha ezintathu) inkulu kakhulu kune-AQ-5200 kunye ne-AO Smith AO-US-200, kodwa ubomi besihluzo obucetyiswayo buyafana, iinyanga ezintandathu. Kwaye iindleko zayo zangaphambili kunye neendleko zokutshintsha isihluzo ziphezulu (malunga needola ezingama-80 zase-US kwiseti okanye iidola ezili-160 zase-US ngonyaka). Ke ngoko, linganisa iingenelo zayo kunye neendleko eziphezulu.
I-Claryum Direct Connect ingafakwa ngaphandle kokubhoboza kwaye ihambisa ukuya kuthi ga kwi-1.5 yeegaloni zamanzi ahluziweyo ngomzuzu ngempompo yakho ekhoyo.
I-Aquasana's Claryum Direct Connect iqhagamshela ngqo kwi-faucet yakho ekhoyo, nto leyo eyenza ukuba ibe lukhetho olunomtsalane kakhulu kubantu abaqeshileyo (basenokungavumelekanga ukutshintsha indawo yabo) kunye nabo bangenako ukufaka i-filter faucet eyahlukileyo. Akunyanzelekanga nokuba ifakwe eludongeni lwekhabhathi yesinki - ingafakwa nje ecaleni kwayo. Inika iziqinisekiso ezifanayo ze-ANSI/NSF ezingama-77 njengezinye iindlela zethu ze-Aquasana kunye ne-AO Smith, kwaye inokubonelela ngee-1.5 gallons zamanzi ahluziweyo ngomzuzu, ngaphezulu kwezinye iimveliso. Umthamo we-filter olinganiselweyo yi-784 gallons, okanye malunga neenyanga ezintandathu zokusetyenziswa. Kodwa ayinayo i-sediment pre-filter, ngoko ke ukuba uneengxaki ze-sediment, ayilokhetho lulungileyo kuba iya kuxinana. Kwaye inkulu kakhulu—20½ x 4½ intshi—ngoko ke ukuba ikhabhathi yakho yesinki incinci okanye ixinene, isenokungafaneleki.
I-Aquasana AQ-5200 ifumene isiqinisekiso esinobungcolisi obuninzi, ifumaneka ngokubanzi, ixabiso layo lifikeleleka, kwaye inesakhiwo esincinci. Yinkqubo yokuqala yokucoca amanzi engaphantsi kwetanki esiyikhangelayo.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 ngokweziqinisekiso, iinkcukacha kunye nobukhulu. Yahlukile kwiLowe's kwaye ngenxa yoko ayifumaneki lula kangako.
I-AQ-5300+ inesiqinisekiso esifanayo esibalaseleyo, kodwa ngenxa yesantya sokuhamba kwamanzi esiphezulu kunye nomthamo wokucoca, ifanelekile kumakhaya asebenzisa amanzi amaninzi, kodwa ixabiso liphezulu kwaye ithatha indawo engaphezulu phantsi kwesinki.
I-Claryum Direct Connect ingafakwa ngaphandle kokubhoboza kwaye ihambisa ukuya kuthi ga kwi-1.5 yeegaloni zamanzi ahluziweyo ngomzuzu ngempompo yakho ekhoyo.
Ndibe ndivavanya izihluzo zamanzi zeWirecutter ukusukela ngo-2016. Kwingxelo yam, ndibe nengxoxo eneenkcukacha nombutho oqinisekisa izihluzo ukuze ndiqonde indlela oluqhutywe ngayo uvavanyo lwabo, kwaye ndangena kwisiseko sabo sedatha yoluntu ukuqinisekisa ukuba ingxelo yomenzi ixhaswe kuvavanyo lwesatifikethi. Ndithethe nabameli babavelisi abaninzi bezihluzo zamanzi, kuquka uAquasana/AO Smith, uFiltrete, uBrita, kunye noPur, ukuze ndibabuze ukuba bathini. Kwaye ndibone ngokwam zonke iindlela zethu, kuba ukuhlala ixesha elide, ukuqina kunye nokulungelelana komsebenzisi kubaluleke kakhulu kwizixhobo ozisebenzisayo amaxesha amaninzi ngemini. Owayesakuba yingcali ye-NOAA uJohn Holecek waphanda waza wabhala isikhokelo sokuqala sesihluzo samanzi seWirecutter, wenza iimvavanyo zakhe, wayalela ezinye iimvavanyo ezizimeleyo, waza wandifundisa okuninzi endikwaziyo. Umsebenzi wam wakhelwe kwisiseko sakhe.
Ngelishwa, akukho mpendulo ifanayo yokuba ingaba isihluzo samanzi siyafuneka na. E-United States, unikezelo lwamanzi kawonke-wonke lulawulwa yi-EPA ngokuhambelana noMthetho waManzi acocekileyo, kwaye amanzi aphuma kwizityalo zonyango lwamanzi kawonke-wonke kufuneka ahlangabezane nemigangatho engqongqo yomgangatho. Kodwa ayizizo zonke izinto ezingcolisayo ezilawulwayo. Ngokufanayo, izinto ezingcolisayo zinokungena emanzini emva kokuphuma kwisityalo sonyango ngokungena okanye ukuphuma kwimibhobho evuzayo (PDF). Unyango lwamanzi olwenziwe (okanye olungakhathalelwanga) kumzi-mveliso lunokwenza kube nzima ukuvuza kwimibhobho esezantsi—njengoko kwenzekileyo eFlint, eMichigan.
Ukuze uqonde ngokuchanekileyo izithako ezikumanzi xa umthengisi eshiya ifektri, ungafumana ingxelo yokuzithemba kwabathengi ye-EPA yomthengisi wasekuhlaleni kwi-Intanethi; ukuba akunjalo, bonke abathengisi bamanzi kawonke-wonke kufuneka bakunike i-CCR yabo ngokweemfuno zakho. Nangona kunjalo, ngenxa yongcoliseko olunokubakho oluvela emlanjeni, indlela ekuphela kwayo yokufumanisa ukwakheka kwamanzi akho kukubuza ilebhu yomgangatho wamanzi yasekuhlaleni ukuba ivavanye.
Ngokusekelwe kumava: okukhona indlu yakho okanye uluntu lwakho lukhula, kokukhona umngcipheko wongcoliseko oluya ezantsi komlambo uphezulu. I-Arhente yoKhuseleko lweNdalo yase-US yathi “izindlu ezakhiwe ngaphambi kowama-1986 zinokusebenzisa imibhobho yelothe, izixhobo, kunye ne-solder” - izinto ezindala ezazikade zingahlangabezani neemfuno zangoku. Ubudala bukwanyusa amathuba okungcoliswa kwamanzi angaphantsi komhlaba ashiywe lishishini langaphambili lolawulo, elinokuba yingozi, ingakumbi xa lidibene nokuwohloka okunxulunyaniswa nemibhobho engaphantsi komhlaba egugayo.
Ukuba usapho lwakho lusela amanzi okusela angaphezu kweelitha ezimbini ukuya kwezintathu ngosuku, ngoko isihluzo esingaphantsi kwesinki sinokuba ngcono kunesihluzo setanki. Inkqubo engaphantsi kwesinki inika amanzi okusela ahluziweyo xa kufuneka, ngaphandle kokulinda ukugqitywa kwenkqubo yokucoca, njengetanki yamanzi. Ukucoca "okufunekayo" kuthetha ukuba inkqubo engaphantsi kwesinki inokubonelela ngamanzi aneleyo okupheka-umzekelo, ungazalisa imbiza ngamanzi ahluziweyo ukupheka ipasta, kodwa awusoze uyizalise kwakhona imbiza ngokuphindaphindiweyo ngenxa yoku.
Xa kuthelekiswa nezihluzo zesinki, izihluzo eziphantsi kwesinki zihlala zinamandla amakhulu kwaye zisebenza ixesha elide - zihlala zingamakhulu eegaloni kunye neenyanga ezintandathu nangaphezulu, ngelixa uninzi lwezihluzo zesinki zingama-40 eegaloni kunye neenyanga ezimbini. Ngenxa yokuba izihluzo ezingaphantsi kwesinki zisebenzisa uxinzelelo lwamanzi endaweni yomxhuzulane ukutyhala amanzi kwisihluzo, izihluzo zazo zinokuba nzima ngakumbi, ukuze zisuse uluhlu olubanzi lwezinto ezingcolisayo ezinokubakho.
Ingxaki kukuba zibiza kakhulu kunezihluzi zepitcher, kwaye ixabiso elipheleleyo kunye nexesha eliqhelekileyo lokutshintsha izihluzi nazo zibiza kakhulu. Le nkqubo ikwathatha indawo kwikhabhathi yesinki ebinokusetyenziselwa ukugcina izinto.
Ukufakela isihluzo phantsi kwesinki kufuna ukufakwa kwezixhobo ezisisiseko zombhobho kunye neplanga, kodwa lo msebenzi ulula kuphela ukuba isinki yakho sele inomngxuma owahlukileyo wompompo. Ukuba akunjalo, kufuneka ukhuphe indawo yempompo eyakhelwe ngaphakathi (ungayibona idiski ephakanyisiweyo kwisinki yentsimbi, okanye uphawu kwisinki yelitye elenziweyo). Ukuba umngxuma wokubetha awukho, kufuneka ugqobhoze umngxuma kwisinki. Ukuba isinki yakho ifakwe ezantsi, kufuneka ugqobhoze umngxuma kwikhawuntara. Ukuba okwangoku unesixhobo sokuhambisa isepha, umngxuma womoya kwisitya sokuhlamba izitya, okanye isitshizi esiphathwa ngesandla kwisinki, ungayisusa kwaye uyifake apho.
Emva kokuvavanya, sitshintshe isihluzo sePur Pitcher esingasasebenziyo ngeFaster Pour Pitcher filter.
Esi sikhokelo simalunga nohlobo oluthile lwesihluzo esingaphantsi kwesinki: ezo zisebenzisa isihluzo sekhatriji kwaye zithumela amanzi ahluziweyo kwimpompo eyahlukileyo. Ezi zezona zihluzo zidumileyo ezingaphantsi kwesinki. Zithatha indawo encinci kakhulu kwaye zihlala kulula ukuzifaka nokuzigcina. Zisebenzisa izinto ezifaka i-adsorbent—ngokuqhelekileyo ii-activated carbon kunye ne-ion exchange resins, njengezihluzo zetanki yamanzi—ukubopha nokuphelisa ukungcola. Asithethi ngezihluzo, iinkqubo ze-reverse osmosis, okanye ezinye ii-pitchers okanye izisasazi ezifakwe kwiimpompo.
Ukuqinisekisa ukuba sicebisa kuphela izihluzi ezithembekileyo, besisoloko sigxininisa ukuba ukhetho lwethu luphumelele isiqinisekiso somgangatho weshishini: i-ANSI/NSF. I-American National Standards Institute kunye ne-NSF International ziintlangano zabucala ezingenzi nzuzo ezisebenzisana ne-EPA, abameli beshishini, kunye nezinye iingcali ukuseka imigangatho engqongqo yomgangatho kunye neenkqubo zokuvavanya amawaka eemveliso, kuquka izihluzi zamanzi. Iilabhoratri ezimbini eziphambili zokuqinisekisa izihluzi zamanzi yi-NSF International ngokwayo kunye ne-Water Quality Association (WQA). Zombini zivunyiwe ngokupheleleyo yi-ANSI kunye neKhansile yeMigangatho yaseKhanada eMntla Melika, zinokuvavanywa ukuze zifumane isiqinisekiso se-ANSI/NSF, kwaye zombini kufuneka zithobele imigangatho yovavanyo kunye neenkqubo ezifanayo. Isihluzi sinokuhlangabezana kuphela nemigangatho yokuqinisekisa emva kokuba sidlule ixesha elide esililindeleyo. Sebenzisa iisampulu "ezinzima" ezilungisiweyo, ezingcoliseke kakhulu kunamanzi amaninzi epompo.
Kule khokelo, sigxila kwiifilitha ezine-chlorine, i-lead, kunye ne-VOC (eyaziwa ngokuba yi-volatible organic compound).
Isatifikethi se-chlorine (phantsi kwe-ANSI/Standard 42) sibalulekile kuba i-chlorine idla ngokuba yimbangela ephambili yamanzi empompini “anencasa embi”. Kodwa oku kuphantse kube yinkohliso: phantse zonke iintlobo zezihluzi zamanzi ziphumelele isatifikethi sazo.
Isiqinisekiso se-lead kunzima ukusifumana kuba sithetha ukunciphisa izisombululo ezityebileyo nge-lead ngaphezulu kwama-99%.
Isatifikethi se-VOC sikwangumceli mngeni kuba kuthetha ukuba isihluzo sinokususa iikhompawundi zendalo ezingaphezu kwama-50, kuquka ii-biocides ezininzi eziqhelekileyo kunye nezinto ezisetyenziswa kwimizi-mveliso. Ayizizo zonke izihluzi ezingaphantsi kwesinki ezinezi ziqinisekiso zimbini, ngoko ke ngokugxila kwizihluzi ezineziqinisekiso ezibini, sichonge ezo zisebenza kakuhle kakhulu.
Sinciphise uphando lwethu saza sakhetha izihluzi ezaziqinisekiswe phantsi komgangatho omtsha we-ANSI/NSF 401, ogubungela izinto ezingcolisayo ezivelayo, ezifana namayeza, ezifumaneka ngakumbi emanzini aseMelika. Ngokufanayo, ayizizo zonke izihluzi ezinesatifikethi se-401, ngoko ke izihluzi ezinaso (kunye nesatifikethi se-lead kunye ne-VOC) liqela elikhetha kakhulu.
Kule nxalenye ingqongqo, emva koko sikhangela ezo zinomthamo omncinci weegaloni ezingama-500. Oku kulingana nobomi bokucoca obumalunga neenyanga ezi-6 xa zisetyenziswa kakhulu (iigaloni ezingama-2¾ ngosuku). Kwiintsapho ezininzi, oku kwanele ukuhlangabezana neemfuno zokusela nokupheka zemihla ngemihla. (Umenzi ubonelela ngeshedyuli yokutshintsha isihluzo ecetyiswayo, ngesiqhelo kwiinyanga kuneegaloni; silandela ezi ngcebiso kuvavanyo lwethu kunye nokubala iindleko. Sicebisa ukuba sisebenzise rhoqo indawo yomenzi wokuqala endaweni yesihluzo somntu wesithathu.)
Okokugqibela, silinganise iindleko zangaphambili zenkqubo yonke kunye neendleko eziqhubekayo zokutshintsha isihluzi. Asikabeki umda wexabiso eliphantsi okanye eliphezulu, kodwa uphando lwethu lubonisa ukuba nangona iindleko zangaphambili ziqala kwi-US$100 ukuya kwi-US$1,250, kwaye iindleko zesihluzi ziqala kwi-US$60 ukuya phantse kwi-US$300, la mahluko awaphezulu kakhulu. Imodeli ebiza kakhulu kwiinkcukacha. Sifumene iintlobo ezahlukeneyo zezihluzi ezingaphantsi kwesinki ezibiza kakuhle ngaphantsi kwe-US$200, ngelixa zibonelela ngesiqinisekiso esihle kunye nobomi obude. Aba baba ngabaphumeleleyo kuthi. Ukongeza, sikwakhangela:
Ngexesha lophando, ngamanye amaxesha siye sadibana neengxelo ezibuhlungu zokuvuza ezivela kumnini wesihluzo samanzi phantsi kwesinki. Ekubeni isihluzo siqhagamshelwe kumbhobho wokungena kwamanzi abandayo ngombhobho, ukuba isixhumi okanye ipayipi yaphukile, amanzi aya kuphuma de ivalvu yokuvala ivalwe-oko kuthetha ukuba kungathatha iiyure okanye iintsuku ukuba ufumane ingxaki, eya kukunika iziphumo ezibi. Umonakalo wamanzi. Oku akuqhelekanga, kodwa kufuneka ulinganisele iingozi xa ucinga ngokuthenga isihluzo phantsi kwesinki. Ukuba uyasithenga, nceda ulandele imiyalelo yokufakela ngononophelo, uqaphele ukuba ungaweli imisonto yesixhumi, uze uvule amanzi kancinci ukuze ujonge ukuvuza.
Isihluzi se-reverse osmosis okanye i-R/O ekuqaleni sasisebenzisa uhlobo olufanayo lwesihluzi sekhatriji njengoko sikhethile apha, kodwa songeze indlela yesibini yokucoca i-reverse osmosis: i-membrane enemingxuma emincinci evumela amanzi ukuba adlule kodwa ihluze iiminerali ezinyibilikisiweyo. Izinto kunye nezinye izinto.
Singaxoxa nzulu ngezihluzi ze-R/O kwizikhokelo ezizayo. Apha, sizigatyile ngokupheleleyo. Xa kuthelekiswa nezihluzi zokufunxa amanzi, zibonelela ngeenzuzo ezilinganiselweyo zokusebenza; zivelisa amanzi amaninzi amdaka (ngesiqhelo iilitha ezi-4 zamanzi “achithayo” ngegaloni nganye yokufunxa amanzi), ngelixa izihluzi zokufunxa amanzi zingathathi ndawo; zithatha indawo. Zinkulu kakhulu kuba, ngokungafaniyo nezihluzi zokufunxa amanzi, zisebenzisa iitanki ezili-1 okanye ezili-2 zeelitha ukugcina amanzi ahluziweyo; zicotha kakhulu kunezihluzi zokufunxa amanzi phantsi kwesinki.
Kwiminyaka embalwa edlulileyo, senze uvavanyo lwelabhoratri kwiifilitha zamanzi. Isigqibo esiphambili esisifumene kwiimviwo kukuba isiqinisekiso se-ANSI/NSF siyindlela ethembekileyo yokulinganisa ukusebenza kweefilitha. Ngenxa yobunzima obukhulu bovavanyo lwesiqinisekiso, oku akumangalisi. Ukususela ngoko, sithembele kwisiqinisekiso se-ANSI/NSF endaweni yovavanyo lwethu olulinganiselweyo ukukhetha abakhuphisana nathi.
Ngowama-2018, savavanya inkqubo yokucoca amanzi edumileyo iBig Berkey, eyayingaqinisekiswanga yi-ANSI/NSF, kodwa yathi ivavanywe kakhulu ngokuhambelana nemigangatho ye-ANSI/NSF. Loo mava aqinisa ngakumbi ukugxininisa kwethu kwisiqinisekiso sokwenyani se-ANSI/NSF kunye nokungathembi kwethu ingxelo ethi "ivavanyiwe yi-ANSI/NSF".
Ukususela ngoko, kuquka nowama-2019, iimvavanyo zethu zigxile ekusebenziseni izinto zokwenyani kunye neempawu ezahlukeneyo ezisebenzayo kunye neentsilelo eziya kubonakala xa usebenzisa ezi mveliso.
I-Aquasana AQ-5200 ifumene isiqinisekiso esinobungcolisi obuninzi, ifumaneka ngokubanzi, ixabiso layo lifikeleleka, kwaye inesakhiwo esincinci. Yinkqubo yokuqala yokucoca amanzi engaphantsi kwetanki esiyikhangelayo.
Sikhethe i-Aquasana AQ-5200, ekwaziwa ngokuba yi-Aquasana Claryum Dual-Stage. Okwangoku, uphawu lwayo olubalulekileyo kukuba isihluzo sayo sifumene isiqinisekiso se-ANSI/NSF esingcono phakathi kwabakhuphisana nathi, kubandakanya i-chlorine, i-chloramine, i-lead, i-mercury, i-VOC, iintlobo ngeentlobo ze-"emerging pollutions", kunye ne-perfluorooctanoic acid kunye ne-Perfluorooctane sulfonic acid. Ukongeza, izixhobo zayo ze-faucet kunye ne-plumbing zenziwe ngesinyithi esiqinileyo, esingcono kuneeplastiki ezisetyenziswa ngabanye abavelisi. Kwaye le nkqubo ikwancinci kakhulu. Okokugqibela, i-Aquasana AQ-5200 yenye yezona mveliso zixabisekileyo esizifumene kwisihluzo phantsi kwesinki. Ixabiso elihlawulelwayo lenkqubo yonke (isihluzo, indlu, i-faucet kunye ne-hardware) lidla ngokuba yi-US$140, kwaye ezimbini ziyi-US$60. Buyisela isihluzo. Oku kuncinci kunabaninzi abakhuphisana nabo abaneziqinisekiso ezibuthathaka.
I-Aquasana AQ-5200 iphumelele isiqinisekiso se-ANSI/NSF (PDF) kwaye inokusingatha izinto ezingcolisayo ezingama-77. Kunye ne-Aquasana AQ-5300+ efanayo eqinisekisiweyo kunye ne-AO Smith AO-US-200, oku kwenza i-AQ-5200 ibe yeyona nkqubo yokuqinisekisa inamandla esiyithandayo. (I-AO Smith yafumana i-Aquasana ngo-2016 kwaye yamkela uninzi lwetekhnoloji yayo; i-AO Smith ayinazicwangciso zokuphelisa uthotho lwe-Aquasana.) Ngokwahlukileyo koko, i-Pur Pitcher Filter egqwesileyo ene-Lead Reduction iqinisekisiwe kwi-23.
Ezi ziqinisekiso ziquka i-chlorine, esetyenziselwa ukubulala iintsholongwane kwiindawo zamanzi zikamasipala kwaye yeyona nto iphambili ebangela “ivumba” lamanzi empompini; i-lead, enokukhutshwa kwimibhobho emidala kunye ne-pipe solder; i-mercury; i-Cryptosporidium ephilayo kunye ne-Giardia, Iintsholongwane ezimbini ezinokubakho; i-chloramine sisibulali-ntsholongwane se-chloramine esiqhubekayo, esisetyenziswa ngakumbi kwizityalo zokucoca kumazantsi e-United States, apho i-chlorine ecocekileyo iya konakala ngokukhawuleza emanzini afudumeleyo. I-Aquasana AQ-5200 ikwaphumelele isiqinisekiso se-15 “evelayo”, esanda kwiinkqubo zokubonelela ngamanzi kawonke-wonke, kubandakanya i-bisphenol A, i-ibuprofen, kunye ne-estrone (i-estrogen esetyenziselwa ukuthintela inzala); Kwi-PFOA kunye ne-PFOS-fluorine-compounds ezisetyenziselwa ukwenza izinto ezinganamatheliyo, kwaye yafumana ingcebiso yezempilo ye-EPA ngoFebruwari 2019. (Ngexesha lokubonisana, abavelisi abathathu kuphela bolu hlobo lwesihluzi abafumene isiqinisekiso se-PFOA/S, esenza oku kuphawuleke ngakumbi.) Ikwaphumelele isiqinisekiso se-VOC. Oku kuthetha ukuba inokususa ngempumelelo iikhompawundi ezahlukeneyo ze-organic ezingaphezu kwama-50, kuquka izibulali-zinambuzane ezininzi kunye nezinto ezisetyenziswa kwimizi-mveliso.
Ukongeza kwii-resin ze-carbon esebenzayo kunye nee-ion exchange (uninzi, ukuba azikho zonke, izihluzi ezingaphantsi kwetanki zixhaphakile), i-Aquasana ikwasebenzisa ubuchwepheshe obubini bokucoca ukuze ifumane isiqinisekiso. Kwi-chloramines, yongeza i-catalytic carbon, oluluhlobo lwe-activated carbon olunemingxuma ngakumbi oluveliswa ngokunyanga i-carbon ngegesi yobushushu obuphezulu. Kwi-Cryptosporidium kunye ne-Giardia, i-Aquasana yenza izihluzi ngokunciphisa ubungakanani be-pore ukuya kwi-0.5 microns, eyaneleyo ukubamba ngokwasemzimbeni.
Isiqinisekiso esihle kakhulu sesihluzo se-Aquasana AQ-5200 sesona sizathu siphambili sokuba sikhethe sona. Kodwa uyilo kunye nezinto zaso zisenza sahluke. I-faucet yenziwe ngentsimbi eqinileyo, kunye nesixhobo esinomfanekiso we-T esidibanisa isihluzo kumbhobho. Abanye abakhuphisana nabo basebenzisa iplastiki kwenye okanye ezimbini zazo, nto leyo enciphisa iindleko, kodwa inyusa umngcipheko weempazamo zokudityaniswa kwemisonto kunye nokufakelwa. I-AQ-5200 isebenzisa izixhobo zokucinezela ukuqinisekisa ukuvalwa okuqinileyo nokukhuselekileyo phakathi kombhobho wakho kunye nombhobho weplastiki othwala amanzi ukuya kwisihluzo kunye nempompo; abanye abakhuphisana nabo basebenzisa izixhobo ezilula zokutyhala, ezingakhuselekanga kakhulu. I-faucet ye-AQ-5200 ifumaneka ngeendlela ezintathu (i-nickel ebhrashiweyo, i-chrome epholisiweyo kunye ne-bronze enamafutha), kwaye abanye abakhuphisana nabo abanalo ukhetho.
Siyayithanda ne-compact form factor yenkqubo ye-AQ-5200. Isebenzisa izihluzi ezimbini, ngasinye sikhulu kancinci kune-soda can; ezinye izihluzi, kuquka i-Aquasana AQ-5300+ ngezantsi, zilingana nebhotile yelitha. Emva kokufaka isihluzi kwi-mounting bracket, ubukhulu be-AQ-5200 buyi-9 intshi ukuphakama, i-8 intshi ububanzi, kunye ne-4 intshi ubunzulu; i-Aquasana AQ-5300+ yi-13 x 12 x 4 intshi. Oku kuthetha ukuba i-AQ-5200 ithatha indawo encinci kakhulu kwikhabhinethi yesinki, ingafakwa kwindawo encinci engenakufakwa ziinkqubo ezinkulu, kwaye ishiya indawo engaphezulu yokugcina phantsi kwesinki. Udinga malunga ne-11 intshi yendawo ethe nkqo (elinganiswe ukusuka phezulu kwesinki) ukuvumela isihluzi ukuba sitshintshwe, kunye ne-9 intshi yendawo ethe tye engaphazanyiswanga eludongeni lwekhabhinethi ukuze ufake isinki.
I-AQ-5200 ihlolwe kakuhle kwiifilitha zamanzi, ineenkwenkwezi ezi-4.5 kwiingxelo ezingaphezulu kwama-800 kwiwebhusayithi ye-Aquasana (kwiinkwenkwezi ezi-5), kunye neenkwenkwezi ezi-4.5 kwiingxelo eziphantse zibe ngama-500 kwi-Home Depot.
Okokugqibela, i-Aquasana AQ-5200 okwangoku ixabisa malunga ne-US$140 kuyo yonke inkqubo (idla ngokuba kufutshane ne-US$100), kwaye iseti yezihluzo zokutshintsha ixabisa i-US$60 (ixesha ngalinye lokutshintsha leenyanga ezintandathu yi-US$120 ngonyaka). I-Aquasana AQ- I-5200 yenye yeemveliso ezixabisekileyo zabakhuphisana nathi, ixabisa amakhulu eedola kunezinye iimodeli ezingaqinisekiswanga kakhulu. Esi sixhobo siquka isibali-xesha esiya kuqala ukukhala xa kufuneka utshintshe isihluzo, kodwa sicebisa ukuba usete nesikhumbuzo sekhalenda esiphindaphindwayo kwifowuni yakho. (Akunakwenzeka ukuba usiphoswe.)
Xa kuthelekiswa nabanye abakhuphisana nabo, i-Aquasana AQ-5200 inesantya sokuhamba esiphezulu esiphantsi (0.5 gpm vs. 0.72 okanye ngaphezulu) kunye nomthamo ophantsi (500 gallons vs. 750 okanye ngaphezulu). Oku kubangelwa ngqo sisihluzo sayo esincinci ngokwasemzimbeni. Ngokubanzi, sikholelwa ukuba ezi ntsilelo zincinci zithintelwa bubuncinci bayo. Ukuba uyazi ukuba ufuna ukuhamba okuphezulu kunye nomthamo, i-Aquasana AQ-5300+ inomthamo olinganiselweyo we-0.72 gpm kunye ne-800 gallons, kodwa ngeshedyuli efanayo yokutshintshwa kwesihluzo seenyanga ezintandathu, i-Aquasana Claryum Direct Connect inesantya sokuhamba esifikelela kwi-1.5 gpm kwaye Ilinganiswe kwiigaloni ezingama-784 kunye neenyanga ezintandathu.
