I-Wirecutter isekela abafundi.Uma uthenga ngesixhumanisi esikuwebhusayithi yethu, singathola ikhomishana esebenzisana nayo.Funda kabanzi
Siphinde senza i-Aquasana Claryum Direct Connect yaba ukukhetha okuhle-kulula ukuyifaka futhi inganikeza ukugeleza kwamanzi okuphezulu kompompi abakhona.
Noma ubani ophuza ngaphezu kwamalitha ambalwa amanzi okuphuza ngosuku angase athande ukusebenzisa uhlelo lokuhlunga ngaphansi kwethangi njenge-Aquasana AQ-5200.Uma uthanda (noma udinga) amanzi ahlungiwe, lokhu kungahlinzekwa ngokuqhubekayo kusuka kumpompi ohlukile njengoba kudingeka.Sincoma i-Aquasana AQ-5200 ngoba isitifiketi sayo sihamba phambili kuwo wonke amasistimu esiwatholile.
I-Aquasana AQ-5200 ithole isitifiketi esingcolisa kakhulu, itholakala kabanzi, inenani elifanele, futhi inokwakheka okuhlangene.Iwuhlelo lokuqala lokuhlunga amanzi ngaphansi kwethangi esilufunayo.
I-Aquasana AQ-5200 isidlulise isitifiketi se-ANSI/NSF futhi ingaqeda ukungcola okucishe kube ngu-77 okuhlukene, okuhlanganisa umthofu, i-mercury, izakhi ze-organic eziguquguqukayo, izidakamizwa, nezinye izinto ezingavamile ukuthunjwa izimbangi.Ingenye yezihlungi ezimbalwa kakhulu eziqinisekiswe i-PFOA ne-PFOS.Lezi zinhlanganisela zibandakanyeka ekwenziweni kwezinto ezinganamatheli futhi zithole iseluleko sezempilo se-EPA ngoFebhuwari 2019.
Izindleko zokushintsha isethi yezihlungi cishe zingama-US$60, noma isikhathi sezinyanga eziyisithupha esinconywe i-Aquasana singama-US$120 ngonyaka.Ngaphezu kwalokho, uhlelo likhulu kuphela kunamathini ambalwa e-soda futhi aluthathi isikhala esiningi esibalulekile ngaphansi kwesinki.Lolu hlelo olusetshenziswa kabanzi lusebenzisa i-hardware yensimbi yekhwalithi ephezulu, futhi ompompi bayo bafika ngezindlela ezihlukahlukene.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 mayelana nesitifiketi, imininingwane kanye nobukhulu.Ihlukile kweka-Lowe ngakho-ke ayitholakali kakhulu.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 kuzo zonke izici ezibalulekile.(Lokhu kungenxa yokuthi u-AO Smith wathola i-Aquasana ngo-2016.) Inesitifiketi esifanayo esihle kakhulu, i-hardware yensimbi yonke, kanye ne-compact form factor, kodwa ngenxa yokuthi ithengiswa kuphela kwa-Lowe, uhla lwayo lokuthengisa alubanzi, futhi i-faucet yayo Kukhona. ukuphela okukodwa kuphela: i-nickel ebhulashiwe.Uma lokhu kufanelana nesitayela sakho, sincoma ukuthenga phakathi kwamamodeli amabili ngentengo: eyodwa noma enye ivamise ukwehliswa.Izindleko zokushintsha isihlungi ziyefana: cishe u-$60 ngesethi, noma u-$120 ngonyaka ngomjikelezo wezinyanga eziyisithupha otuswe ngu-AO Smith.
I-AQ-5300+ inesitifiketi esifanayo esihle kakhulu, kodwa ngezinga eliphezulu lokugeleza namandla okuhlunga, ifanele imizi esebenzisa amanzi amaningi, kodwa izindleko ziphakeme futhi ithatha indawo eyengeziwe ngaphansi kukasinki.
Ukugeleza okuphezulu kwe-Aquasana AQ-5300+ kunezitifiketi ze-ANSI/NSF ezingama-77 njengeminye imikhiqizo esiyithandayo, kodwa inikeza ukugeleza okuphezulu (amalitha angu-0.72 kanye no-0.5 ngomzuzu) kanye nomthamo wokuhlunga (amalitha angu-800 nangama-500).Lokhu kwenza kube ukukhetha kokuqala emindenini edinga amanzi amaningi ahlungiwe futhi efuna ukuwasebenzisa ngokushesha ngangokunokwenzeka.Ingeza futhi isihlungi sangaphambili se-sediment, esingatholakali ku-AQ-5200;lokhu kungase kunwebe izinga eliphezulu lokugeleza kwesisefo esingcolisayo ezindlini ezinothe ngamanzi ensika.Ngamanye amazwi, imodeli ye-AQ-5300+ (efakwe isihlungi samabhodlela amalitha amathathu) inkulu kakhulu kune-AQ-5200 ne-AO Smith AO-US-200, kodwa impilo yesihlungi enconyiwe iyafana, izinyanga eziyisithupha.Futhi izindleko zayo zangaphambili kanye nezindleko zokushintsha isihlungi ziphakeme (cishe amadola ase-US angama-80 ngesethi noma amadola angu-160 ase-US ngonyaka).Ngakho-ke, linganisa izinzuzo zayo kanye nezindleko eziphakeme.
I-Claryum Direct Connect ingafakwa ngaphandle kokubhola futhi ilethe amalitha amanzi ahlungiwe afinyelela kwangu-1.5 ngomzuzu ngompompi wakho okhona.
I-Claryum Direct Connect ye-Aquasana ixhuma ngqo kumpompi osuvele ukhona, okuyenza ibe inketho ekhangayo ngokukhethekile kubaqashi (bangase bavinjelwe ukushintsha indawo yabo) kanye nalabo abangakwazi ukufaka impompi yesihlungi ehlukile.Akudingeki ukuthi ifakwe odongeni lwekhabethe likasinki-ingamane ibekwe eceleni kwayo.Inikeza izitifiketi ezifanayo ezingama-77 ze-ANSI/NSF njengezinye izinketho zethu ze-Aquasana ne-AO Smith, futhi ingahlinzeka ngamalitha afinyelela ku-1.5 amanzi ahlungiwe ngomzuzu, ngaphezu kweminye imikhiqizo.Umthamo olinganiselwe wesihlungi ungamalitha angama-784, noma cishe izinyanga eziyisithupha zokusetshenziswa.Kodwa ayinaso isihlungi sangaphambili se-sediment, ngakho-ke uma unezinkinga ze-sediment, akuyona into enhle ngoba izovala.Futhi inkulu kakhulu—amayintshi angu-20½ x 4½—ngakho-ke uma ikhabethe lakho likasinki lilincane noma liminyene, lingase lingafaneleki.
I-Aquasana AQ-5200 ithole isitifiketi esingcolisa kakhulu, itholakala kabanzi, inenani elifanele, futhi inokwakheka okuhlangene.Iwuhlelo lokuqala lokuhlunga amanzi ngaphansi kwethangi esilufunayo.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 mayelana nesitifiketi, imininingwane kanye nobukhulu.Ihlukile kweka-Lowe ngakho-ke ayitholakali kakhulu.
I-AQ-5300+ inesitifiketi esifanayo esihle kakhulu, kodwa ngezinga eliphezulu lokugeleza namandla okuhlunga, ifanele imizi esebenzisa amanzi amaningi, kodwa izindleko ziphakeme futhi ithatha indawo eyengeziwe ngaphansi kukasinki.
I-Claryum Direct Connect ingafakwa ngaphandle kokubhola futhi ilethe amalitha amanzi ahlungiwe afinyelela kwangu-1.5 ngomzuzu ngompompi wakho okhona.
Bengilokhu ngihlola izihlungi zamanzi ze-Wirecutter kusukela ngo-2016. Embikweni wami, ngibe nengxoxo enemininingwane nenhlangano yezitifiketi zokuhlunga ukuze ngiqonde ukuthi ukuhlolwa kwazo kwenziwa kanjani, futhi ngajula kusizindalwazi sazo somphakathi ukuze ngiqinisekise ukuthi isitatimende somkhiqizi sisekelwe ekuhlolweni kwesitifiketi. .Ngiphinde ngakhuluma nabamele abakhiqizi abaningi bokuhlunga amanzi, okuhlanganisa i-Aquasana/AO Smith, i-Filtrete, i-Brita, ne-Pur, ukubabuza ukuthi bathini.Futhi ngizibonele mathupha zonke izinketho zethu, ngoba ukuphila konke, ukuqina kanye nokufaneleka komsebenzisi kubaluleke kakhulu kumadivayisi owasebenzisa izikhathi eziningi ngosuku.Owayengusosayensi we-NOAA uJohn Holecek wacwaninga futhi wabhala inkomba yokuqala yesihlungi samanzi e-Wirecutter, wenza okwakhe ukuhlolwa, wanikeza izivivinyo ezengeziwe ezizimele, futhi wangifundisa okuningi engikwaziyo.Umsebenzi wami wakhelwe phezu kwesisekelo sakhe.
Ngeshwa, ayikho impendulo efanayo yokuthi isisefo samanzi siyadingeka yini.E-United States, ukuhlinzekwa kwamanzi omphakathi kulawulwa yi-EPA ngokuhambisana noMthetho Wamanzi Ahlanzekile, futhi izindawo zokuhlanza amanzi zomphakathi eziphuma emanzini kufanele zihlangabezane nezindinganiso eziqinile zekhwalithi.Kodwa akuzona zonke izinto ezingase zibe ukungcola ezilawulwayo.Ngokufanayo, izinto ezingcolisayo zingangena emanzini ngemva kokuphuma endaweni yokuhlanza ngokungena noma ngokuvuza emapayipini avuzayo (PDF).Ukuhlanzwa kwamanzi okwenziwa (noma ukunganakwa) efekthri kungabhebhethekisa ukugeleza kwamapayipi omfula—njengoba kwenzeka e-Flint, Michigan.
Ukuze uqonde ngokunembile izithako emanzini lapho umphakeli ehamba efekthri, ngokuvamile ungathola umbiko wokuthenjwa wabathengi we-EPA yomphakeli wendawo ku-inthanethi;uma kungenjalo, bonke abaphakeli bamanzi bomphakathi kufanele bakunikeze i-CCR yabo ngokwezidingo zakho.Kodwa-ke, ngenxa yokungcola okungaba khona ezansi nomfula, okuwukuphela kwendlela yokunquma ukwakheka kwamanzi akho ukucela ilabhorethri yezinga lamanzi yendawo ukuze ihlolwe.
Ngokusekelwe kokuhlangenwe nakho: lapho indlu yakho noma umphakathi wakho umdala, kuba nkulu ingozi yokungcoliswa komfula.I-Environmental Protection Agency yase-United States yathi “izindlu ezakhiwa ngaphambi kuka-1986 maningi amathuba okuba zisebenzise amapayipi omthofu, izinto ezisetshenziswayo, kanye ne-solder”—izinto ezake zaba izinto ezindala ezazingafinyeleli izimfuneko zamanje.Iminyaka yobudala iphinda inyuse amathuba okungcoliswa kwamanzi angaphansi komhlaba ashiywe yimboni yangaphambili yokulawula, okungaba yingozi, ikakhulukazi uma kuhlangene nokuwohloka okuhambisana nokuguga kwamapayipi angaphansi komhlaba.
Uma umndeni wakho uphuza ngaphezu kwamalitha amabili kuya kwamathathu amanzi okuphuza ngosuku, khona-ke isihlungi esingaphansi kukasinki singase sibe ngcono kunesihlungi sethangi.Uhlelo olungaphansi kukasinki luhlinzeka ngamanzi okuphuza ahlungiwe lapho kudingeka, ngaphandle kokulinda ukuqedwa kwenqubo yokuhlunga, njengethangi lamanzi.Ukuhlunga “Okufunwayo” kusho nokuthi uhlelo olungaphansi kukasinki lunganikeza amanzi anele okupheka-ngokwesibonelo, ungagcwalisa ibhodwe ngamanzi ahlungiwe ukuze upheke i-pasta, kodwa awusoze wagcwalisa ibhodwe ngokuphindaphindiwe ngalokhu.
Uma kuqhathaniswa nezihlungi zikasinki, izihlungi ezingaphansi kukasinki zivame ukuba nomthamo omkhulu nempilo yesevisi ende-imvamisa amakhulu amamalitha nezinyanga eziyisithupha noma ngaphezulu, kuyilapho izihlungi eziningi ze-sink zingamalitha angama-40 Nezinyanga ezimbili.Ngenxa yokuthi izihlungi ezingaphansi kukasinki zisebenzisa umfutho wamanzi esikhundleni se-gravity ukuze ziphushe amanzi ngesihlungi, izihlungi zazo zingaminyene, ngakho zingakwazi ukususa uhla olubanzi lwezinto ezingaba ukungcola.
Okubi ukuthi zibiza kakhulu kunezihlungi ze-pitcher, futhi inani eliphelele nesikhathi esimaphakathi sokushintsha izihlungi nakho kuyabiza kakhulu.Uhlelo luphinde luthathe isikhala ekhabetheni likasinki ebesingasetshenziselwa ukulondoloza.
Ukufaka isihlungi ngaphansi kukasinki kudinga ukufakwa kwamapayipi okuyisisekelo nokufakwa kwehadiwe, kodwa lo msebenzi ulula kuphela uma usinki wakho usuvele unembobo kampompi ehlukile.Uma kungenjalo, udinga ukukhipha indawo yesimpompi esakhelwe ngaphakathi (ungabona i-disc ephakanyisiwe kusinki wensimbi, noma uphawu kusinki yamatshe okwenziwa).Uma imbobo ye-percussion ingekho, udinga ukubhoboza imbobo kusinki.Uma usinki wakho efakwe ngezansi, udinga futhi ukubhoboza imbobo ku-countertop.Uma njengamanje unomshini wokukhipha insipho, igebe lomoya emshinini wokuwasha izitsha, noma isifutho esibanjwa ngesandla kusinki, ungasikhipha futhi usifake lapho.
Ngemva kokuhlola, sishintshe isihlungi se-Pur Pitcher esiyekiwe safaka isihlungi se-Faster Pour Pitcher.
Lo mhlahlandlela umayelana nohlobo oluthile lwesihlungi esingaphansi kukasinki: lezo ezisebenzisa isihlungi se-cartridge bese zithumela amanzi ahlungiwe empompini ohlukile.Lezi izihlungi ezingaphansi kukasinki ezaziwa kakhulu.Zithatha indawo encane kakhulu futhi ngokuvamile kulula ukuzifaka nokuyinakekela.Basebenzisa izinto ze-adsorbent-imvamisa i-carbon activated kanye ne-ion exchange resins, njengezihlungi zethangi lamanzi-ukubopha nokuqeda ukungcola.Asikhulumi ngezihlungi, amasistimu e-osmosis ahlehlayo, noma ezinye izimbiza noma izihlinzeki ezifakwe kompompi.
Ukuqinisekisa ukuthi sincoma kuphela izihlungi ezithembekile, besihlala sigcizelela ukuthi ukukhetha kwethu kuphumelele isitifiketi esijwayelekile somkhakha: ANSI/NSF.I-American National Standards Institute kanye ne-NSF International yizinhlangano ezizimele ezingenzi nzuzo ezisebenza ne-EPA, abamele izimboni, nabanye ochwepheshe ukuze basungule izindinganiso eziqinile zekhwalithi nezinqubo zokuhlola zezinkulungwane zemikhiqizo, okuhlanganisa nezihlungi zamanzi.Amalabhorethri amabili ayinhloko wokunikeza izitifiketi abahlanza amanzi yi-NSF International ngokwayo kanye neNhlangano Yekhwalithi Yamanzi (WQA).Kokubili kugunyazwe ngokugcwele yi-ANSI kanye noMkhandlu Wamazinga WaseCanada eNyakatho Melika, kungahlolelwa isitifiketi se-ANSI/NSF, futhi kokubili kufanele kuhambisane ncamashi namazinga okuhlola afana ncamashí nezinqubomgomo.Isihlungi singahlangabezana nezindinganiso zesitifiketi kuphela ngemva kokuba seseqe kude kakhulu impilo yaso elindelwe.Sebenzisa amasampula “ayinselele” alungisiwe, angcoliswe kakhulu kunamanzi amaningi ompompi.
Kulo mhlahlandlela, sigxila kuzihlungi ezinezitifiketi ze-chlorine, umthofu, kanye ne-VOC (i-volatile organic compound).
Ukuqinisekiswa kwe-chlorine (ngaphansi kwe-ANSI/I-Standard 42) kubalulekile ngoba i-chlorine ngokuvamile iyimbangela eyinhloko yamanzi kampompi “ambi”.Kodwa lokhu kucishe kube i-gimmick: cishe zonke izinhlobo zezihlungi zamanzi ziphumelele isitifiketi sazo.
Ukuthola isitifiketi somthofu kunzima ukuzuza ngoba kusho ukunciphisa izixazululo ezinothile ngomthofu ngaphezu kwama-99%.
Ukunikezwa kwesitifiketi se-VOC nakho kuyinselele ngoba kusho ukuthi isihlungi singasusa izinhlanganisela zezinto eziphilayo ezingaphezu kuka-50, okuhlanganisa ama-biocides amaningi avamile kanye nezandulela zezimboni.Akuzona zonke izihlungi ezingaphansi kukasinki ezinalezi zitifiketi ezimbili, ngakho-ke ngokugxila kuzihlungi ezinezitifiketi ezimbili, sihlonze lezo ezisebenza kahle kakhulu.
Sinciphise usesho lwethu ngokuqhubekayo futhi sakhetha izihlungi eziphinde zaqinisekiswa ngaphansi kwe-ANSI/NSF Standard 401 entsha, ehlanganisa ukungcola okuvelayo, njengezidakamizwa, ezitholakala kakhulu emanzini aseMelika.Ngokufanayo, akuzona zonke izihlungi ezinezitifiketi ze-401, ngakho-ke izihlungi ezinaso (kanye nesitifiketi sokuhola nesitifiketi se-VOC) ziyiqembu elikhetha kakhulu.
Kulesi sigaba esingaphansi esiqinile, sibe sesibheka labo abanomthamo omncane ongamalitha angama-500.Lokhu kulingana nempilo yesihlungi cishe izinyanga eziyisi-6 ngaphansi kokusetshenziswa kakhulu (amalitha angu-2¾ ngosuku).Emindenini eminingi, lokhu kwanele ukuhlangabezana nezidingo zokuphuza nokupheka nsuku zonke.(Umkhiqizi uhlinzeka ngohlelo olunconyiwe lokubuyisela isihlungi, ngokuvamile ezinyangeni kunemalitha; silandela lezi zincomo ekuhlaziyeni kwethu nasezibalweni zezindleko. Sincoma ukuthi ngaso sonke isikhathi sisebenzise isishintshi somkhiqizi sangempela esikhundleni sesihlungi esivela eceleni.)
Ekugcineni, silinganise izindleko zangaphambili zayo yonke isistimu kanye nezindleko eziqhubekayo zokushintsha isihlungi.Asikawubeki umkhawulo wamanani aphansi noma aphezulu, kodwa ucwaningo lwethu lubonisa ukuthi nakuba izindleko zangaphambili zisukela ku-US$100 kuya ku-US$1,250, futhi izindleko zokuhlunga zisukela ku-US$60 kuya cishe kuma-US$300, lo mehluko awukho mkhulu kakhulu.Imodeli ebiza kakhulu ekucacisweni.Sithole izinhlobo ezimbalwa zezihlungi ezingaphansi kukasinki ezibiza kahle ngaphansi kuka-US$200, kuyilapho zinikeza isitifiketi esihle kakhulu nokuphila isikhathi eside.Laba bagcine sebengowamanqamu.Ngaphezu kwalokho, sifuna futhi:
Phakathi nocwaningo, ngezikhathi ezithile sihlangabezane nemibiko yokuvuza eyinhlekelele evela kumnikazi wesihlungi samanzi ngaphansi kukasinki.Njengoba isihlungi sixhunywe epayipini lokungena lamanzi abandayo ngepayipi, uma isixhumi noma ipayipi liphukile, amanzi azophuma kuze kuvalwe ivalvu yokuvala—okusho ukuthi kungase kuthathe amahora noma izinsuku ukuze uthole. inkinga, ezokunikeza Letha imiphumela engathi sína.Ukulimala kwamanzi.Lokhu akuvamile, kodwa udinga ukukala izingozi lapho ucabangela ukuthenga isihlungi ngaphansi kukasinki.Uma uyithenga, sicela ulandele imiyalelo yokuyifaka ngokucophelela, uqaphele ukuthi ungaweli izintambo zokuxhuma, bese uvula amanzi kancane kancane ukuze uhlole ukuvuza.
Isihlungi se-osmosis ehlanekezelwe noma isihlungi se-R/O ekuqaleni sasisebenzisa uhlobo olufanayo lwesihlungi se-cartridge njengoba sikhethe lapha, kodwa sengeza indlela yokuhlunga ye-osmosis yesibili ehlehlayo: ulwelwesi olunezimbotshana ezinhle oluvumela amanzi ukuthi adlule kodwa luhlunge amaminerali ancibilikisiwe.Izinto kanye nezinye izinto.
Singase sixoxe ngokujulile ngezihlungi ze-R/O kumhlahlandlela wesikhathi esizayo.Lapha, sabenqaba ngokuphelele.Uma kuqhathaniswa nezihlungi ze-adsorption, zinikeza izinzuzo ezilinganiselwe zokusebenza;bakhiqiza amanzi amaningi angcolile (imvamisa amalitha angu-4 amanzi amoshiwe "ashaywayo" ngegaloni lokuhlunga), kuyilapho izihlungi ze-adsorption zingenzi;bathatha indawo Yinkulu kakhulu ngoba, ngokungafani nezihlungi ze-adsorption, zisebenzisa i-gallon engu-1 noma amathangi angu-2 ukugcina amanzi ahlungiwe;anensa kakhulu kunezihlungi ze-adsorption ngaphansi kukasinki.
Eminyakeni embalwa edlule, senze izivivinyo zaselabhorethri ezihlungini zamanzi.Isiphetho esiyinhloko esisithathile ekuhlolweni ukuthi isitifiketi se-ANSI/NSF isilinganiso esithembekile sokusebenza kwesihlungi.Uma kubhekwa ukuqina okwedlulele kokuhlolwa kwesitifiketi, lokhu akumangazi.Kusukela lapho, siye sathembela ekutholeni isitifiketi se-ANSI/NSF esikhundleni sokuhlola kwethu okulinganiselwe ukuze sikhethe izimbangi zethu.
Ngo-2018, sahlola isistimu yokuhlunga amanzi e-Big Berkey edumile, engazange iqinisekiswe i-ANSI/NSF, kodwa yathi ihlolwe kakhulu ngokuvumelana namazinga e-ANSI/NSF.Lokho okwenziwayo kwahlanganisa nokugcizelela kwethu ekutholeni isitifiketi sangempela se-ANSI/NSF kanye nokungathembani kwethu isitatimende “se-ANSI/NSF ehloliwe”.
Kusukela lapho, okuhlanganisa no-2019, ukuhlola kwethu kugxile ekusebenzisekeni komhlaba wangempela nasezicini ezingokoqobo ezihlukahlukene kanye nokushiyeka okuzobonakala uma usebenzisa le mikhiqizo.
I-Aquasana AQ-5200 ithole isitifiketi esingcolisa kakhulu, itholakala kabanzi, inenani elifanele, futhi inokwakheka okuhlangene.Iwuhlelo lokuqala lokuhlunga amanzi ngaphansi kwethangi esilufunayo.
Sikhethe i-Aquasana AQ-5200, eyaziwa nangokuthi i-Aquasana Claryum Dual-Stage.Kuze kube manje, isici sayo esibaluleke kakhulu ukuthi isihlungi saso sithole isitifiketi esihle kakhulu se-ANSI/NSF phakathi kwezimbangi zethu, okuhlanganisa i-chlorine, i-chloramine, i-lead, i-mercury, i-VOC, izinhlobonhlobo “zezinto ezingcolisayo ezivelayo”, ne-perfluorooctanoic acid ne-Perfluorooctane sulfonic acid.Ngaphezu kwalokho, i-faucet yayo kanye ne-plumbing hardware yenziwe ngensimbi eqinile, engcono kunepulasitiki esetshenziswa abanye abakhiqizi.Futhi lolu hlelo lubuye luhlanganiswe kakhulu.Ekugcineni, i-Aquasana AQ-5200 ingenye yemikhiqizo ebaluleke kakhulu esiyithole kusihlungi ngaphansi kukasinki.Izindleko ezikhokhelwa ngaphambili zalo lonke uhlelo (isihlungi, indlu, umpompi kanye nehadiwe) ngokuvamile zingu-$140, kanti ezimbili ziyi-US$60.Faka esikhundleni isihlungi.Lokhu kungaphansi kwezimbangi eziningi ezinezitifiketi ezibuthakathaka.
I-Aquasana AQ-5200 isiphumelele isitifiketi se-ANSI/NSF (PDF) futhi ingakwazi ukuphatha ukungcola okungu-77.Kanye ne-Aquasana AQ-5300+ efanayo eqinisekisiwe kanye ne-AO Smith AO-US-200, lokhu kwenza i-AQ-5200 ibe uhlelo lwesitifiketi esinamandla kakhulu esisikhethayo.(I-AO Smith ithole i-Aquasana ngo-2016 futhi yamukela iningi lobuchwepheshe bayo; u-AO Smith akanazo izinhlelo zokuqeda uchungechunge lwe-Aquasana.) Ngokuphambene, Isihlungi esihle kakhulu se-Pur Pitcher esinokuNciphiswa komthofu siqinisekiswa ku-23.
Lezi zitifiketi zihlanganisa i-chlorine, esetshenziselwa ukubulala amagciwane emanzini kamasipala futhi iyimbangela enkulu yamanzi ampompi "anukayo";ukuhola, okungase kukhishwe kumapayipi amadala kanye ne-solder yamapayipi;i-mercury;phila i-Cryptosporidium ne-Giardia , Amagciwane angaba khona amabili;I-chloramine iyisibulala-magciwane esiphikelelayo se-chloramine, esisetshenziswa kakhulu ezitshalweni zokuhlunga eningizimu ye-United States, lapho i-chlorine ehlanzekile izowohloka ngokushesha emanzini afudumele.I-Aquasana AQ-5200 iphinde yaphasisa isitifiketi se-15 "esingcolisayo esisafufusa", esanda ezinhlelweni zokuhlinzeka ngamanzi omphakathi, okuhlanganisa i-bisphenol A, ibuprofen, ne-estrone (i-estrogen esetshenziselwa ukuvimbela inzalo);Okwamakhompiyutha asuselwa ku-PFOA kanye ne-PFOS-fluorine asetshenziselwa ukwenza izinto ezingagxili, futhi athole iseluleko sezempilo se-EPA ngoFebhuwari 2019. (Ngesikhathi sokubonisana, abakhiqizi abathathu kuphela balolu hlobo lwesihlungi bathole isitifiketi se-PFOA/S, okuthe kwenza lokhu kuphawuleke ngokukhethekile.) Iphinde yaphasisa nesitifiketi se-VOC.Lokhu kusho ukuthi ingakwazi ukususa ngempumelelo inhlanganisela yezinto eziphilayo ezingaphezu kuka-50, kuhlanganise nezibulala-zinambuzane eziningi kanye nezandulela zezimboni.
