Sihlola ngokuzimela konke esikuncomayo. Uma uthenga ngezixhumanisi zethu, singase sithole ikhomishini. Thola okwengeziwe>
Ukuthengiswa kuka-Okthoba kwe-Amazon kuyaqhubeka. Ukuze uthole amanye amadili e-Wirecutter okufanele ukuthengwa, hlola uhlu lwethu lwamadili amahle kakhulu e-Prime Day.
Noma ubani ophuza amanzi okuphuza angaphezu kwamagalani ambalwa ngosuku cishe uzokwaneliseka kakhulu ngohlelo lokuhlunga olungaphansi kwesinki njenge-Aquasana AQ-5200. Ngokungafani nejagi, isihlungi esingaphansi kwesinki sinikeza ukuhlinzekwa kwamanzi okuqhubekayo uma kudingeka. Sincoma i-Aquasana AQ-5200 ngoba izitifiketi zayo zingcono kakhulu kunanoma yiluphi uhlelo esilutholile; zifaka (njengezinye izixazululo zethu lapha) i-chlorine, i-lead, i-mercury, i-PFAS, izinhlobo ezahlukene zezibulala-zinambuzane, kanye ne-microplastics.
I-Aquasana AQ-5200 iqinisekiswe yi-ANSI/NSF futhi ingasusa cishe ukungcola okuningi, okuhlanganisa i-lead, i-mercury, izibulala-zinambuzane, ama-microplastic, imithi kanye nezinye izinto ezingabanjwa ngabancintisani abambalwa. Ingenye yezihlungi ezimbalwa eziqinisekiswe ukuthi ziqukethe i-PFOA kanye ne-PFOS, amakhemikhali amabili ahlala njalo akhathaza i-Environmental Protection Agency.
Izindleko zokushintsha isethi yezihlungi zingaba ngu-$60, noma u-$120 ngonyaka, ngokusekelwe emjikelezweni wokushintsha wezinyanga eziyisithupha onconyiwe yi-Aquasana. Futhi uhlelo lukhulu kancane kunezitini ezimbalwa zesoda, ngakho aluthathi isikhala esiningi esibalulekile ngaphansi kwesinki. Lunezinsimbi zensimbi ezisezingeni eliphezulu futhi ompompi bayatholakala ngezindlela ezahlukahlukene zokuqeda.
I-AO Smith I-AO-US-200 ifana ne-Aquasana AQ-5200 ngazo zonke izici ezibalulekile. (Lokho kungenxa yokuthi i-AO Smith yathenga i-Aquasana ngo-2016.) Inezici ezifanayo ze-premium, ihadiwe yensimbi yonke, kanye ne-compact form factor, kodwa njengoba ithengiswa kwa-Lowe's kuphela, ayitholakali kabanzi futhi ama-faucet ayo anokuphela okukodwa. : i-nickel ebhulashiwe. Izindleko zokufaka esikhundleni sesihlungi ziyafana: cishe u-$60 ngesethi ngayinye, noma u-$120 ngonyaka emjikelezweni wezinyanga eziyisithupha onconywe yi-AO Smith.
Inezitifiketi ezinhle kakhulu njenge-AQ-5200, kanye namakhono aphezulu okugeleza nokuhlunga kune-AQ-5200, kanye nesihlungi sangaphambi kokususa ama-rust deposits.
I-Aquasana AQ-5300+ Max Flow inezitifiketi ezinhle kakhulu njengezo esizikhethile, kodwa inikeza ukugeleza okuphezulu (0.72 gpm vs. 0.5 gpm) kanye nomthamo wokuhlunga (800 gpm vs. 500). Lokhu kwenza kube inketho efanelekile emindenini edinga amanzi amaningi ahlungiwe futhi ewafuna ngokushesha okukhulu. Iphinde ingeze isihlungi sangaphambi kokungcola i-AQ-5200 engenaso; lokhu kungandisa isihlungi esingcolisayo ngamazinga aphezulu okugeleza emakhaya anamanzi agcwele ukungcola. Kodwa-ke, i-AQ-5300+ (enezihlungi ezinobukhulu bebhodlela lamalitha amathathu) inkulu kakhulu kune-AQ-5200, futhi izindleko zokuqala kanye nokushintsha isihlungi ziphakeme kancane (cishe ama-$80 ngesethi noma ama-$160 ngonyaka).
Ifakwa ngaphandle kokubhoboza futhi iletha amanzi afinyelela ku-1.5 amalitha ngomzuzu ngokusebenzisa ompompi abakhona.
I-Claryum Direct Connect ka-Aquasana ixhuma ngqo kuma-faucet akhona, okwenza kube inketho ekhangayo kakhulu kubaqashi (abangase bavinjelwe ukuhamba) nalabo abangakwazi ukufaka i-faucet ehlukile yokuhlunga. Akudingeki nokuthi ifakwe odongeni lwekhabhinethi ngaphansi kwesinki, imane ime eceleni kwayo. Inezitifiketi ze-ANSI/NSF ezifanayo nezinye izinhlobo ze-Aquasana ne-AO Smith futhi ingaletha amalitha afinyelela ku-1.5 amanzi ahlungiwe ngomzuzu. Lesi sihlungi sinamandla alinganiselwa ku-784 amalitha futhi kufanele sithathe cishe izinyanga eziyisithupha. Kodwa asinayo i-sediment pre-filter. Ngakho-ke, uma unezinkinga nge-sediment, lena akuyona inketho engcono kakhulu njengoba ingavimbeka kalula. Futhi inkulu—20.5 x 4.5 amasentimitha—ngakho uma ikhabhinethi yakho yesinki incane noma igcwele kakhulu, ingase ingalingani.
Inezitifiketi ezinhle kakhulu njenge-AQ-5200, kanye namakhono aphezulu okugeleza nokuhlunga kune-AQ-5200, kanye nesihlungi sangaphambi kokususa ama-rust deposits.
Ifakwa ngaphandle kokubhoboza futhi iletha amanzi afinyelela ku-1.5 amalitha ngomzuzu ngokusebenzisa ompompi abakhona.
Bengilokhu ngihlola izihlungi zamanzi ze-Wirecutter kusukela ngo-2016. Embikweni wami, ngikhulume ngokuningiliziwe nezinhlangano eziqinisekisa izihlungi ukuze ngiqonde ukuthi ukuhlolwa kwazo kwenziwa kanjani, futhi ngahlola imininingwane yazo yomphakathi ukuqinisekisa ukuthi izimangalo zabakhiqizi zisekelwa yi: Ukuhlolwa Okuqinisekisiwe. Ngikhulume nabameleli babakhiqizi abaningana bezihlungi zamanzi, okuhlanganisa i-Aquasana/AO Smith, i-Filtrete, i-Brita kanye ne-Pur, ukuze ngiphikise izimangalo zabo. Mina mathupha ngizame zonke izinketho zethu ngoba ukuthembeka okuphelele, ukuqina, kanye nokusebenziseka kahle kubaluleke kakhulu kudivayisi esetshenziswa izikhathi eziningana ngosuku.
Owayengusosayensi we-NOAA uJohn Holecek wacwaninga futhi wabhala incwadi yokuqala yokuhlunga amanzi ye-Wirecutter, wenza ukuhlolwa kwakhe, wayala ukuhlolwa okwengeziwe okuzimele, futhi wangifundisa okuningi kwalokho engikwaziyo. Umsebenzi wami usekelwe emsebenzini wakhe.
Ngeshwa, ayikho impendulo evamile embuzweni wokuthi ngabe udinga isihlungi samanzi noma cha. E-United States, ukuphakelwa kwamanzi omphakathi kulawulwa yi-US Environmental Protection Agency ngaphansi koMthetho Wamanzi Ahlanzekile, futhi amanzi aphuma ezitshalweni zokuhlanza amanzi omphakathi kumele ahlangabezane nezindinganiso eziqinile zekhwalithi. Kodwa akuzona zonke izinto ezingcolisayo ezingaba khona ezilawulwayo. Ngaphezu kwalokho, izinto ezingcolisayo zingangena emanzini ngemva kokuphuma esitshalweni sokuhlanza, kungaba ngamapayipi avuzayo (PDF) noma ngokuphuma emapayipini ngokwawo. Ukwelashwa kwamanzi okwenziwa (noma okunganakwa) esitshalweni kungenza kube kubi kakhulu ukuphuma kwamanzi emapayipini angezansi komfula, njengoba kwenzeka eFlint, eMichigan.
Ukuze uthole ukuthi yini ngempela esemanzini omhlinzeki wakho, ngokuvamile ungasesha ku-inthanethi umbiko wokuqiniseka kwabathengi ovunyelwe yi-EPA womhlinzeki wakho wendawo; ngaphandle kwalokho, bonke abahlinzeki bamanzi omphakathi kudingeka bakunikeze ama-CCR abo uma becela. Kodwa ngenxa yokungcola okungenzeka kube khona ngemuva komfula, okuwukuphela kwendlela yokuthola ukuthi yini esemanzini asekhaya lakho ukukhokhela ilebhu yekhwalithi yamanzi yendawo ukuze iwahlole.
Njengomthetho ojwayelekile, uma ikhaya lakho noma indawo yakho indala, kulapho ingozi yokungcoliswa kwamanzi ikhula khona. I-Environmental Protection Agency ibika ukuthi “izindlu ezakhiwe ngaphambi kuka-1986 zinamathuba amaningi okuba namapayipi e-lead, izinto zokwakha kanye ne-solder”—izinto ezindala, ezazivamile ezingahlangabezani namakhodi amanje. Ukuguga kwandisa namathuba okungcoliswa kwamanzi angaphansi komhlaba agugayo yizimboni ezilawulwa ngaphambilini, okungaba yingozi, ikakhulukazi uma kuhlanganiswa nokuwohloka kwamapayipi angaphansi komhlaba okuhlobene nobudala.
Uma umndeni wakho usebenzisa amanzi okuphuza angaphezu kwamagaloni amabili kuya kwamathathu ngosuku, isihlungi samanzi esingaphansi kwesinki singaba ukukhetha okungcono kunesihlungi sembiza. Izinhlelo ezingaphansi kwesinki ziletha amanzi okuphuza ahlungiwe uma kudingeka, okususa isidingo sokulinda inqubo yokuhlunga ukuthi iphele njengoba kunjalo ngembiza. Ukuhlunga lapho kudingeka kusho nokuthi uhlelo olungaphansi kwesinki lunganikeza amanzi anele okupheka—isibonelo, ungagcwalisa imbiza ngamanzi ahlungiwe ukupheka i-pasta, kodwa awusoze wadingeka ukuthi ugcwalise imbiza ngaleyo njongo.
Uma kuqhathaniswa nezihlungi ze-pitcher, izihlungi ze-under-sink zivame ukuba nomthamo omkhulu kanye nokuphila isikhathi eside—ngokuvamile amakhulu amaningana amalitha nezinyanga eziyisithupha noma ngaphezulu uma kuqhathaniswa nosayizi wamalitha angu-40 wezihlungi eziningi ze-pitcher nezinyanga ezimbili. Ngenxa yokuthi izihlungi ze-under-sink zisebenzisa umfutho wamanzi esikhundleni samandla adonsela phansi ukuze zisunduze amanzi ngesihlungi, izihlungi zazo zingaba nzima kakhulu futhi ngaleyo ndlela zisuse uhla olubanzi lwezinto ezingaba khona ezingcolisayo.
Okubi ukuthi zibiza kakhulu ngaphambili kunezihlungi ze-pitcher, kanti izihlungi ezishintshayo nazo zibiza kakhulu ngokwesilinganiso nangokuhamba kwesikhathi. Uhlelo luphinde luthathe isikhala sekhabethe ngaphansi kwesinki ebesingasetshenziselwa ukugcina izinto.
Ukufaka isihlungi esingaphansi kwesinki kudinga ukufakwa kwamapayipi kanye nehadiwe okuyisisekelo, kodwa umsebenzi ulula kuphela uma isinki yakho isivele inesikhala sompompi ohlukile. Ngaphandle kwalokho, kuzodingeka ususe enye yezindawo zompompi ezakhelwe ngaphakathi (idiski ephakanyisiwe kusinki yensimbi noma uphawu kusinki yetshe elenziwe ngokwenziwa). Uma ungenayo imbobo yokugoqa, kuzodingeka ubhoboze imbobo kusinki noma kukhawunta uma isinki yakho ingafakwanga kahle. Uma une-dispenser yensipho noma i-sprayer yesandla kusinki yakho, ungayisusa bese ufaka i-pount. (Ungayifaki i-pount lapho kunesikhala somoya - lokhu kwenzelwa ukuvimbela amanzi okuhlanza angcolile ukuthi angangeni kumshini wokuwasha izitsha.)
Cishe ingxenye yawo wonke amanzi ompompi aqukethe amakhemikhali angapheli. Nansi indlela yokunquma ukuthi usengozini yini futhi unciphise ukuchayeka kwakho.
Lo mhlahlandlela umayelana nohlobo oluthile lwesihlungi esingaphansi kwesinki: lezo ezisebenzisa isihlungi sekhatriji. Zithatha isikhala esincane kakhulu futhi ngokuvamile kulula ukuzifaka nokuzinakekela. Zisebenzisa izinto ezifaka i-adsorbent (ngokuvamile ama-activated carbon kanye nama-ion exchange resins njengezihlungi ze-pitcher) ukubopha nokuqeda ukungcola. Iningi lifakwa kumpompi ohlukile (ofakiwe), okusho ukuthi uzodinga imbobo yokufaka ku-countertop; Imbobo eyenzelwe ipayipi lokufafaza izosebenza, noma ungabhoboza imbobo entsha. Asikhulumi ngezihlungi zokufaka impompi, izinhlelo ze-reverse osmosis, noma ezinye izimbiza zamanzi noma izihlinzeki.
Ukuqinisekisa ukuthi sincoma kuphela izihlungi ongazethemba, sihlala sigcizelela ukuthi ukukhetha kwethu kuqinisekiswe ngokwezinga lomkhakha: i-ANSI/NSF. I-American National Standards Institute kanye ne-NSF International yizinhlangano ezizimele, ezingenzi nzuzo ezisebenzisana ne-Environmental Protection Agency, imboni kanye nabanye ochwepheshe ukuthuthukisa amazinga ekhwalithi aqinile kanye nezinqubo zokuhlola izinkulungwane zemikhiqizo, kufaka phakathi izihlungi zamanzi. Amalabhorethri amabili amakhulu okuqinisekisa izihlungi zamanzi yi-NSF International uqobo kanye ne-Water Quality Association (WQA). Yomibili imikhiqizo iqinisekiswe ngokugcwele yi-ANSI kanye ne-Canadian Standards Council eNyakatho Melika ukuze kuhlolwe izitifiketi ze-ANSI/NSF, futhi yomibili kumele ilandele amazinga afanayo kanye nezinqubo zokuhlola. Kuphela ngemva kokusebenzisa amasampula "okuhlola" alungisiwe, ayengcoliswe kakhulu kunamanzi amaningi ompompi, lapho isihlungi sahlala khona isikhathi eside ngaphezu kokuphila obekulindelwe futhi sahlangabezana nezindinganiso zesitifiketi.
Kulo mhlahlandlela, sizogxila ezihlungini eziqinisekiswe ukuthi zine-chlorine, i-lead, kanye nama-volatile organic compounds (ama-VOC).
Isitifiketi se-chlorine sibalulekile ngoba i-chlorine iyimbangela evamile “yephunga elibi” emanzini ompompi. Kodwa lokhu cishe kuyisibusiso: cishe zonke izinhlobo zezihlungi zamanzi ziqinisekisiwe.
Ukuthola isitifiketi se-lead kunzima ngoba kusho ukunciphisa izixazululo ezicebile nge-lead ngamaphesenti angaphezu kuka-99%.
Isitifiketi se-VOC naso siyinselele ngoba kusho ukuthi isihlungi singasusa amakhemikhali angaphezu kuka-50 emvelo, okuhlanganisa nemithi eminingi yokubulala amagciwane evamile kanye nezinto ezisetshenziswa ezimbonini. Akuzona zonke izihlungi ezingaphansi kwesinki ezinezitifiketi zombili, ngakho-ke ngokugxila kuzihlungi ezinezitifiketi zombili, sithole izihlungi ezisebenza kangcono kakhulu.
Sinciphise usesho lwethu kakhulu futhi sakhetha izihlungi ngezitifiketi ezengeziwe ezisezingeni elisha le-ANSI/NSF 401, elihlanganisa ukungcola okuvelayo okutholakala emanzini e-United States, njengemithi. Ngokufanayo, akuzona zonke izihlungi ezinesitifiketi se-401. Ngakho-ke, lezo zikhungo ezinesitifiketi se-401 (kanye nesitifiketi se-lead kanye ne-VOC) ziseqenjini elikhethwe ngokucophelela.
Ngemuva kwalokho, ngaphakathi kwalesi sigaba esiqinile, sifuna imikhiqizo enomthamo omncane wamagalani angu-500. Lokhu kulingana nezinyanga eziyisithupha zokuphila kwesihlungi ngaphansi kokusetshenziswa kakhulu (amagalani angu-2.75 ngosuku). Lawa manzi ahlungiwe anele imindeni eminingi ukuphuza nokupheka nsuku zonke. (Abakhiqizi banikeza amashejuli anconywayo okushintsha isihlungi, ngokuvamile ngezinyanga hhayi ngamagalani; silandela lezi zincomo ezilinganisweni zethu kanye nokubala izindleko. Sincoma njalo ukusebenzisa izingxenye zokushintsha zomkhiqizi wokuqala esikhundleni sezihlungi zenkampani yangaphandle.)
Ekugcineni, silinganise izindleko zokuqala zesistimu yonke ngezindleko eziqhubekayo zokushintsha izihlungi. Asikakabeki phansi noma uphahla lwentengo, kodwa ucwaningo lwethu lukhombisile ukuthi yize izindleko zokuqala zazisukela ku-$100 kuya ku-$1,250 kanti izindleko zokuhlunga zazisukela ku-$60 kuya cishe ku-$300, lo mehluko awuzange uguqule ukusebenza okuphezulu kakhulu. Amamodeli abiza kakhulu. Sithole izihlungi eziningana ezingaphansi kwesinki ezibiza ngaphansi kuka-$200 kodwa zisenezitifiketi ezinhle kakhulu nokuqina. Laba ngabantu ababa ngabafinyeleli bethu bokugcina. Phakathi kwezinye izinto esizifunayo:
Ngesikhathi socwaningo lwethu, ngezinye izikhathi sithole imibiko yokuvuza okubi kakhulu kubanikazi bezihlungi zamanzi ezingaphansi kwesinki. Ngenxa yokuthi isihlungi sixhunywe emanzini abandayo, uma isixhumi noma ipayipi liphuka, amanzi angase avuza kuze kube yilapho ivalvu yokuvala ivala, ngakho kungathatha amahora noma ngisho nezinsuku ukuthola inkinga, okuholela emiphumeleni emibi kuwe. Umonakalo wamanzi. Akuvamile, kodwa uma ucabanga ukuthenga isihlungi esingaphansi kwesinki, udinga ukulinganisa izingozi. Uma uthenge esisodwa, landela imiyalelo yokufaka ngokucophelela, uqaphele ukuthi ungajiki izixhumi ngendlela engafanele, bese uvula amanzi kancane kancane ukuze uhlole ukuvuza. Ukuze uthole ukuthula kwengqondo okwengeziwe (ukuxazulula zonke izinkinga zakho zamapayipi, hhayi isihlungi esingaphansi kwesinki kuphela), cabanga ngokufaka i-smart leak detector.
Izihlungi ze-reverse osmosis (R/O) ekuqaleni zinehlobo olufanayo lwesihlungi se-cartridge njengaleso esisikhethile lapha, kodwa engeza indlela yesibili yokuhlunga i-reverse osmosis: ulwelwesi olunezimbobo ezincane oluvumela amanzi ukuthi adlule kodwa luhlunge amaminerali ancibilikisiwe nezinye izinto.
Singase sixoxe ngezihlungi ze-R/O ngokuningiliziwe esifundweni esizayo. Lapha siyazenqaba ngokuphelele. Zinezinzuzo ezilinganiselwe zokusebenza ngaphezu kwezihlungi zokumunca; zikhiqiza amanzi amaningi angcolile (ngokuvamile amalitha angu-4 amanzi “okugeza” ngegaloni ngalinye elihlungiwe), kanti izihlungi zokumunca azikhiqizi amanzi angcolile; Zithatha isikhala esiningi ngoba, ngokungafani nezihlungi zokumunca, zisebenzisa ithangi elingamagaloni angu-1 noma angu-2 ukugcina amanzi ahlungiwe; futhi zisebenza kancane kakhulu kunezihlungi zokumunca ezingaphansi kwesinki.
Besilokhu sihlola izihlungi zamanzi elabhorethri eminyakeni embalwa edlule, futhi okubalulekile ekuhlolweni kwethu ukuthi isitifiketi se-ANSI/NSF siyisibonakaliso esithembekile sokusebenza kwezihlungi. Lokhu akumangazi uma ubheka ubunzima obukhulu bezivivinyo zezitifiketi. Kusukela ngaleso sikhathi, sithembele esiqinisekisweni se-ANSI/NSF ukukhetha abancintisana nabo kunokuhlola kwethu okulinganiselwe.
Ngo-2018, sahlola uhlelo lokuhlunga amanzi oludumile lweBig Berkey, olungaqinisekisiwe yi-ANSI/NSF kodwa oluthi luhlolwe kabanzi ukuze luhlangabezane nezindinganiso ze-ANSI/NSF. Lokhu okuhlangenwe nakho kwaqinisa ukuzibophezela kwethu ekuqinisekisweni kwe-ANSI/NSF kwangempela kanye nokungazethembi izimangalo ze-“ANSI/NSF Verified”.
Kusukela ngaleso sikhathi, kuhlanganise nango-2019, ukuhlolwa kwethu kugxile ekusebenziseni kwangempela kanye nezici ezisebenzayo kanye nokushiyeka okubonakala njengoba usebenzisa imikhiqizo.
Sikhethe i-Aquasana AQ-5200, eyaziwa nangokuthi i-Aquasana Claryum Dual-Stage. Isici sayo esibaluleke kakhulu ukuthi izihlungi zayo zinezitifiketi ze-ANSI/NSF ezinhle kakhulu phakathi kwezimbangi zethu ze-chlorine, i-chloramines, i-lead, i-mercury, ama-VOC, "izinto eziningi ezingcolisayo ezivelayo," ama-microplastics, kanye ne-PFOA kanye ne-PFOS. Ngaphezu kwalokho, ompompi kanye nezinto ezisetshenziswayo zenziwe ngensimbi eqinile, engcono kunepulasitiki esetshenziswa abanye abakhiqizi. Ngaphezu kwalokho, uhlelo luncane kakhulu. Ekugcineni, i-Aquasana AQ-5200 ingenye yezinketho ezinhle kakhulu esizitholile zezihlungi ezingaphansi kwesinki, lapho lonke uhlelo (isihlungi, indlu, impompi, kanye nehadiwe) ngokuvamile libiza cishe u-$140 ngaphambili noma isethi yezihlungi ezimbili ngo-$60. Lokhu kungaphansi kwabancintisani abaningi abanezitifiketi ezibuthakathaka.
Isitifiketi se-ANSI/NSF (PDF) se-AQ-5200 Siqukethe i-chlorine, esetshenziselwa ukubulala amagciwane ezindaweni zamanzi zikamasipala futhi siyimbangela ehamba phambili “yephunga elibi” emanzini ompompi; i-lead, engaphuma emapayipini amadala kanye ne-pipe solder. ; i-mercury; I-Cryptosporidium Esebenzayo kanye ne-Giardia, amagciwane amabili angaba khona; I-Chloramine iyisibulala-magciwane se-chlorine-ammonia esiqhubekayo esisetshenziswa kakhulu ezitshalweni zokuhlunga eningizimu ye-United States. I-chlorine emsulwa ibola ngokushesha emanzini afudumele. I-AQ-5200 iphinde iqinisekiswe ngokumelene “nezingcolisi eziphumayo” ezingu-15 ezibonakala kakhulu ezindaweni zamanzi, okuhlanganisa i-BPA, i-ibuprofen kanye ne-estrone (i-estrogen esetshenziswa ekulawuleni inzalo), ama-microplastics, kanye ne-PFOA kanye ne-PFOS, amakhemikhali asekelwe ku-fluoride ezimbonini. atholakala kabanzi emanzini ompompi ase-US. Iqinisekiswe futhi yi-VOC. Lokhu kusho ukuthi ingasusa ngempumelelo amakhemikhali angaphezu kuka-50 ahlukene e-organic, okuhlanganisa nezibulala-zinambuzane eziningi kanye nezinto ezisetshenziswa ezimbonini.
Ngaphezu kwe-activated carbon kanye ne-ion exchange resin (esetshenziswa kakhulu ezihlungini ezingaphansi kwesinki, uma kungezona zonke), i-Aquasana isebenzisa ubuchwepheshe obubili bokuhlunga ukuze ithole isitifiketi. Kuma-chloramine, kufakwa i-catalytic carbon, okungukuthi, i-activated carbon, enezimbobo futhi ngenxa yalokho isabela kakhulu, edalwe ngokwelapha i-carbon ngegesi eshisa kakhulu. Ku-cryptosporidium kanye ne-giardia, i-Aquasana ikhiqiza izihlungi ezinobukhulu be-pore obuncishisiwe bube yi-0.5 microns, obuncane ngokwanele ukubamba ngokomzimba.
Ukuqinisekiswa kwesihlungi se-Aquasana AQ-5200 kwakuyisona sizathu esiyinhloko esasenza sayikhetha. Kodwa ukwakheka kwayo nezinto zayo nakho kuyayihlukanisa nezinye. Impompi yenziwe ngensimbi eqinile, njengoba kunjalo nange-T-piece exhumanisa isihlungi nepayipi. Abanye abancintisana nabo basebenzisa ipulasitiki kwenye noma zombili, okunciphisa izindleko kodwa kwandisa ingozi yokuwela izinkinobho nokufakwa okungafanele. I-AQ-5200 isebenzisa izinto zokucindezela ukudala uphawu oluqinile noluvikelekile phakathi kwepayipi nepayipi lepulasitiki elithwala amanzi liye kusihlungi nepayipi. Abanye abancintisana nabo basebenzisa izinto zokufaka ezilula, ezingathembeki kakhulu. Impompi ye-AQ-5200 itholakala ngezindlela ezintathu zokuqeda (i-nickel ebhulashiwe, i-chrome epholishiwe kanye nethusi elibhulashiwe ngamafutha), kuyilapho abanye abancintisana nabo bengakushiyi ithuba.
Sithanda futhi i-compact form factor yesistimu ye-AQ-5200. Isebenzisa izihlungi ezimbili, ngasinye sikhulu kancane kune-soda can; ezinye izihlungi, okuhlanganisa ne-Aquasana AQ-5300+ ngezansi, zenzelwe amabhodlela alitha. Njengoba isihlungi sifakwe ebhulokini lokufaka, i-AQ-5200 inobude obungamasentimitha angu-9, ububanzi obungamasentimitha angu-8, kanye nobubanzi obungamasentimitha angu-4; I-Aquasana AQ-5300+ inobude obungamasentimitha angu-13 x 12 x 4. Lokhu kusho ukuthi i-AQ-5200 ithatha isikhala esincane kakhulu sekhabhinethi elingaphansi kwesinki, okuvumela ukuthi ifakwe ezindaweni eziqinile lapho izinhlelo ezinkulu zingenakufakwa khona, okushiya isikhala esiningi sokugcina esingaphansi kwesinki. Uzodinga cishe amasentimitha angu-11 esikhala esiqondile (esilinganiswa kusukela phezulu kwekhabhinethi phansi) ukuze ufake isihlungi kanye cishe amasentimitha angu-9 esikhala esivulekile esivulekile odongeni lwekhabhinethi ukuze ufake ikhabhinethi.
I-AQ-5200 ithole ukubuyekezwa okuhle kakhulu njengesihlungi samanzi, ithole izinkanyezi ezingu-4.5 kwezingu-5 kwezingu-800 kuwebhusayithi ye-Aquasana kanye nezinkanyezi ezingu-4.5 kwezingu-500 ezitholakala kwa-Home Depot.
Okokugcina, ngentengo yamanje ecishe ibe ngu-$140 kulo lonke uhlelo (ngokuvamile intengo icishe ibe ngu-$100) kanye no-$60 ngesethi yezihlungi zokufaka esikhundleni ($120 ngonyaka ngomjikelezo wokufaka esikhundleni wezinyanga eziyisithupha), i-Aquasana AQ-5200 yilokho esikufunayo. Enye yezinhlinzeko ezinhle kakhulu phakathi kwabancintisanayo futhi ishibhile ngamadola amaningi kunamanye amamodeli anezitifiketi ezincane. Idivayisi ine-timer ekhalayo uma udinga ukushintsha isihlungi, kodwa sincoma ukuthi usethe nezikhumbuzi zekhalenda ezivamile efonini yakho. (Akunakwenzeka ukuthi uphuthelwe yilokhu.)
Uma kuqhathaniswa nabanye abancintisana nabo, i-Aquasana AQ-5200 inesilinganiso sokugeleza esiphezulu esiphansi (0.5 gpm vs. 0.72 noma ngaphezulu) kanye nomthamo omncane (amagaloni angu-500 vs. amagaloni angu-750 noma ngaphezulu). Lokhu kuwumphumela oqondile wosayizi wesihlungi omncane ngokomzimba. Sekukonke, sicabanga ukuthi la maphutha amancane adlula ngobukhulu bawo obuncane. Uma wazi ukuthi udinga ukugeleza okuphezulu nokusebenza, i-Aquasana AQ-5300+ ilinganiswe ku-0.72 GPM kanye namagaloni angu-800 kodwa inesimiso esifanayo sokushintsha isihlungi sezinyanga eziyisithupha, kuyilapho i-Aquasana Claryum Direct Connect inesilinganiso sokugeleza esifinyelela kumagaloni angu-1.5 ngomzuzu. , isilinganiso sokugeleza esilinganiselwe singamagaloni angu-1.5 ngomzuzu. kufika kumagaloni angu-784 nezinyanga eziyisithupha.
Imiyalelo yokusebenza kohlelo lwe-AQ-5200 ayicacile kahle futhi ezinye izingxenye aziboniswa ohlwini lwezingxenye noma kumadayagramu. Lokhu ngeke kukhathaze iningi labanikazi. Ngokuyisisekelo, okudingeka ukwenze nje ukuxhuma amapayipi ambalwa ekuhlinzekeni kwamanzi nasemampompini, futhi konke kuzozichaza ngandlela thile. (Okuhlukile yi-washer yokuhlobisa yensimbi engagqwali, engafakwanga ohlwini; ifakwa kuqala empompini, ilandelwe yi-washer yerabha encane.) Ngokweqiniso, kulokho esikubonile ocwaningweni lwethu. Kodwa sithemba ukuthi iziqondiso zizobuyekezwa esikhathini esizayo. Okwamanje, nansi ividiyo evela ku-Aquasana yokuthi ungayifaka kanjani i-AQ-5200.
Njengoba kushiwo ngenhla esigabeni esithi How We Choose, izihlungi zamanzi ezingaphansi kwesinki (kufaka phakathi i-AQ-5200) ngezinye izikhathi ziyahluleka ngendlela exakile, okubangela umonakalo omkhulu wamanzi uma inkinga ingatholakali futhi ingalungiswa ngokushesha. Qaphela kakhulu lapho ufaka hhayi izixhumi ezixhumanisayo futhi uqinisekisa ukuthi ukuxhumeka kwepayipi kuphephile bese uvula amanzi kancane kancane ukuze ukwazi ukuthola nokulungisa ukuvuza ngaphambi kokuba kube yizinhlekelele. Izihloli zokuvuza ezihlakaniphile zingathola ukuvuza okubi kakhulu, kungakhathaliseki ukuthi imbangela yazo iyini, ngaphambi kokuba zidale umonakalo omkhulu kakhulu.
Njengazo zonke izinhlobo zethu, i-Aquasana AQ-5200 iza ne-faucet yayo ezimele yodwa, engase ingahambisani nesitayela sakho. Ungafaka futhi i-faucet ehlukile oyikhethayo uma nje usayizi wokuxhuma kwe-faucet ungamasentimitha angu-⅜. Kodwa udinga ukuqhathanisa izinga lokugeleza kwayo ne-Aquasana's 0.5 GPM ngoba isitifiketi sesihlungi sisekelwe ezingeni lokugeleza. Sicela uqaphele ukuthi ngokwezobuchwepheshe, ukusebenzisa i-faucet yakho kusho ukuthi uhlelo lwakho alusaqinisekisiwe yi-ANSI/NSF.
Uma usola ukuthi amanzi akho aqukethe indle (umbala ophuzi obangelwa ukugqwala uyinkomba; kanye nolwazi lwangaphambilini nganoma yiluphi uhlobo lwesihlungi, okuhlanganisa nama-pitcher, avala ngaphambi kwesikhathi sawo sokuphila okulindelekile), ungase ufune ukuhlola ezinye izihlungi ezifanayo. I-Aquasana AQ-5300 ene-sediment pre-filter eyengeziwe.
Ithengiswa njengesihlungi samanzi ahlanzekile esinezigaba ezimbili (esilungele ukulunywa) sezinhlelo zokuhlunga amanzi ngaphansi kwesinki, i-AO Smith AO-US-200 ifana ngokusebenza nangokomzimba ne-Aquasana AQ-5200 ephezulu kakhulu ngazo zonke izindlela ezibalulekile. Inezitifiketi ezifanayo ze-ANS/NSF (PDF), usayizi ofanayo ohlangene, ubuchwepheshe bokuhlunga, ukwakhiwa kwensimbi yonke, ukufakwa kokucindezela, izinga lokugeleza elingu-0.5 GPM, kanye nomthamo wamagaloni angu-500. Ivame futhi ukuza nesethi yezihlungi zokufaka esikhundleni ngentengo efanayo. Akukho lutho oluyimfihlakalo ngalokhu: I-AO Smith yathenga i-Aquasana ngo-2016 futhi, okhulumela i-AO Smith wasitshela, "isebenzisa" ulwazi lwe-Aquasana futhi ayinazo izinhlelo zokuqeda uphawu lwe-Aquasana.
