Sibuyekeza ngokuzimela konke esikuncomayo. Singathola ikhomishini uma uthenga ngezixhumanisi zethu. Funda kabanzi >
Senze i-Aquasana Claryum Direct Connect yaba ukukhetha okuhle – kulula ukuyifaka futhi inikeza ukugeleza kwamanzi amaningi kuma-pombi akhona.
Abantu abaphuza amanzi aphuzwayo angaphezu kwamagalani ambalwa ngosuku cishe baneliseke kakhulu ngohlelo lokuhlunga olungaphansi kwesinki njenge-Aquasana AQ-5200. Uma uthanda (noma udinga) amanzi ahlungiwe, lokhu kunganikezwa njalo kusuka empompini ehlukile uma kudingeka. Sincoma i-Aquasana AQ-5200 ngoba isitifiketi sayo singcono kakhulu kunanoma yiluphi uhlelo esilutholile.
Iqinisekiswe yizinto eziningi ezingcolisayo, ezitholakala kabanzi, ezingabizi, futhi ezincane, i-Aquasana AQ-5200 iyisistimu yokuqala yokuhlunga amanzi ngaphansi kwesinki esiyifunayo.
I-Aquasana AQ-5200 iqinisekiswe yi-ANSI/NSF ukususa cishe ukungcola okungu-77 okuhlukene, okuhlanganisa i-lead, i-mercury, ama-organic compounds aguquguqukayo, imithi, nezinye izinto ezingavamile ukuthuthwa yizimbangi. Ingenye yezihlungi ezimbalwa eziqinisekiswe yi-PFOA kanye ne-PFOS, ama-compounds ahilelekile ekwenziweni kwezinto ezinganamatheli, ezithole iseluleko sezempilo se-EPA ngoFebhuwari 2019.
Isethi yezihlungi zokufaka esikhundleni ibiza cishe u-$60, noma u-$120 ngonyaka emjikelezweni wokufaka esikhundleni wezinyanga eziyisithupha onconyiwe yi-Aquasana. Futhi, uhlelo lukhulu kuphela kunezitini ezimbalwa zesoda futhi aluthathi isikhala esiningi esibalulekile ngaphansi kwesinki. Lolu hlelo olusetshenziswa kabanzi lusebenzisa izinsimbi zensimbi ezisezingeni eliphezulu, futhi ama-faucet alo eza ngezindlela ezahlukene zokuqeda.
I-AO Smith AO-US-200 ifana ne-Aquasana AQ-5200 ngokwezitifiketi, imininingwane kanye nobukhulu, futhi itholakala kuphela kwaLowe's, ngakho ayitholakali kabanzi.
I-AO Smith AO-US-200 ifana ne-Aquasana AQ-5200 kuzo zonke izici ezibalulekile. (Lokho kungenxa yokuthi i-AO Smith yathenga i-Aquasana ngo-2016.) Inesitifiketi esifanayo se-premium, ihadiwe yensimbi yonke, kanye ne-compact form factor, kodwa ayisakazeki kangako ngoba ithengiswa kwaLowe's kuphela, futhi i-faucet yayo iza ngokuphela okukodwa. Ukwelashwa: I-Brushed Nickel. Uma lokho kuhambisana nesitayela sakho, sincoma ukuthi uthenge phakathi kwamamodeli amabili ngentengo: eyodwa noma enye ivame ukuncishiswa. Izindleko zokushintsha isihlungi ziyafana: cishe ama-$60 ngesethi, noma ama-$120 ngonyaka ngomjikelezo wezinyanga eziyisithupha ophakanyiswe yi-AO Smith.
I-AQ-5300+ inezitifiketi ezifanayo ezinhle kakhulu kodwa inomthamo ophezulu wokugeleza kanye nokuhlunga emakhaya asebenzisa amanzi amaningi, kodwa abiza kakhulu futhi athatha isikhala esiningi ngaphansi kwesinki.
I-Aquasana AQ-5300+ Max Flow inezitifiketi ze-ANSI/NSF ezingama-77 ezifanayo nezinye izinketho zethu eziphezulu, kodwa inikeza ukugeleza okuphezulu (amagaloni angu-0.72 vs. 0.5 ngomzuzu) kanye nomthamo wokuhlunga (amagaloni angu-800 vs. 500). Lokhu kwenza kube inketho emindenini edinga amanzi amaningi ahlungiwe futhi efuna ukuwathola ngokushesha okukhulu. Iphinde ifake isihlungi sangaphambi kokungcola, i-AQ-5200 engenayo. Lokhu kungase kwandise ukugeleza okuphezulu kwezihlungi zokungcola emakhaya anamanzi agcwele ukungcola. Lokho kusho ukuthi, imodeli ye-AQ-5300+ (enesihlungi samabhodlela angu-3-litre) inkulu kakhulu kune-AQ-5200 kanye ne-AO Smith AO-US-200, kodwa inempilo efanayo yokuhlunga enconywayo yezinyanga eziyi-6. Futhi izindleko zayo zangaphambilini kanye nezindleko zokufaka isihlungi ziphakeme (cishe ama-$80 ngesethi noma ama-$160 ngonyaka). Ngakho-ke linganisa izinzuzo zayo ngezindleko eziphakeme.
I-Claryum Direct Connect ifakwa ngaphandle kokubhoboza imigodi futhi iletha amanzi acwengekile afinyelela ku-1.5 amalitha ngomzuzu ngempompi yakho ekhona.
I-Claryum Direct Connect ka-Aquasana ixhuma ngqo kumpompi wakho okhona, okwenza kube inketho ekhangayo kakhulu kubaqashi (abangase bavinjelwe ukushintsha indawo yabo) nalabo abangakwazi ukufaka impompi yokuhlunga ehlukile. Akudingeki nokuthi ifakwe odongeni lwekhabhinethi yesinki - ingalala ngohlangothi lwayo. Inikeza izitifiketi ezifanayo ezingama-77 ze-ANSI/NSF njengezinye izinketho zethu ze-Aquasana ne-AO Smith, futhi inikeza amalitha amanzi ahlungiwe afinyelela ku-1.5 ngomzuzu, ngaphezu kwezinye. Isihlungi sinamandla alinganiselwe angamalitha angu-784, noma cishe izinyanga eziyisithupha zokusetshenziswa. Kodwa asinayo i-sediment pre-filter, ngakho-ke uma unezinkinga ze-sediment, akuyona inketho enhle ngoba izovimba. Futhi inkulu kakhulu - amasentimitha angu-20½ x 4½ - ngakho uma ikhabhinethi yakho yesinki incane noma igcwele, cishe ngeke ilingane.
Iqinisekiswe yizinto eziningi ezingcolisayo, ezitholakala kabanzi, ezingabizi, futhi ezincane, i-Aquasana AQ-5200 iyisistimu yokuqala yokuhlunga amanzi ngaphansi kwesinki esiyifunayo.
I-AO Smith AO-US-200 ifana ne-Aquasana AQ-5200 ngokwezitifiketi, imininingwane kanye nobukhulu, futhi itholakala kuphela kwaLowe's, ngakho ayitholakali kabanzi.
I-AQ-5300+ inezitifiketi ezifanayo ezinhle kodwa inomthamo ophezulu wokugeleza kanye nokuhlunga emakhaya asebenzisa amanzi amaningi, kodwa abiza kakhulu futhi athatha isikhala esiningi ngaphansi kwesinki.
I-Claryum Direct Connect ifakwa ngaphandle kokubhoboza imigodi futhi iletha amanzi acwengekile afinyelela ku-1.5 amalitha ngomzuzu ngempompi yakho ekhona.
Bengilokhu ngihlola izihlungi zamanzi ze-Wirecutter kusukela ngo-2016. Embikweni wami, ngibe nezingxoxo ezinde nezinhlangano zokuqinisekisa izihlungi ukuze ngiqonde ukuthi ukuhlolwa kwazo kwenziwa kanjani, futhi ngamba ezinqolobaneni zabo zomphakathi ukuqinisekisa ukuthi izimangalo zomkhiqizi zisekelwa yi-Certification test. Ngiphinde ngakhuluma nabamele abakhiqizi bezihlungi zamanzi abaningana, okuhlanganisa i-Aquasana/AO Smith, i-Filtrete, i-Brita kanye ne-Pur, ukuze ngibuze ukuthi bathini. Futhi ngizibonele mathupha zonke izinketho zethu, ngoba ukuhlala kahle, ukuqina, kanye nobungane bokusebenzisa kubalulekile kudivayisi oyisebenzisa izikhathi eziningi ngosuku. Owayengusosayensi we-NOAA uJohn Holecek wacwaninga futhi wabhala iziqondiso zakuqala zezihlungi zamanzi ze-Wirecutter, wenza ukuhlolwa kwakhe, wayala ukuhlolwa okwengeziwe okuzimele, futhi wangifundisa okuningi engikwaziyo. Umsebenzi wami wakhelwe esisekelweni sakhe.
Ngeshwa, ayikho impendulo eyodwa efaneleka kubo bonke yokuthi udinga isihlungi samanzi. E-United States, ukuphakelwa kwamanzi omphakathi kulawulwa yi-EPA ngaphansi koMthetho Wamanzi Ahlanzekile, futhi amanzi aphuma ezitshalweni zokwelapha amanzi omphakathi kumele ahlangabezane nezindinganiso zekhwalithi eziqinile. Kodwa akuzona zonke izinto ezingcolisayo ezingaba khona ezilawulwayo. Ngokufanayo, izinto ezingcolisayo zingangena emanzini ngemva kokuphuma esitshalweni sokwelapha ngamapayipi avuzayo (PDF) noma ngamapayipi ngokwawo. Ukwelashwa kwamanzi esitshalweni (noma ukunganakwa) kungenza kube kubi kakhulu ukugeleza kwamanzi emapayipini angaphansi komfula—njengoba kwenzeka eFlint, eMichigan.
Ukuze uthole ukuthi yini ngempela emanzini omhlinzeki wakho uma ephuma endaweni, ungabheka umbiko wokuqiniseka kwabathengi ogunyazwe yi-EPA ku-inthanethi womhlinzeki wakho wendawo; uma kungenjalo, bonke abahlinzeki bamanzi omphakathi kudingeka bakunikeze i-CCR uma becela. Kodwa ngenxa yokungcola okungenzeka kube khona ngemuva komfula, okuwukuphela kwendlela yokuqiniseka ngamanzi asekhaya lakho ukukhokhela ilebhu yekhwalithi yamanzi yendawo ukuze ihlolwe.
Njengomthetho ojwayelekile: uma ikhaya lakho noma umphakathi wakho ukhula, kulapho ingozi yokungcoliswa kwamanzi ikhula khona. I-EPA ithi “izindlu ezakhiwe ngaphambi kuka-1986 zinamathuba amaningi okusebenzisa amapayipi e-lead, izinto zokwakha kanye ne-solder”—izinto ezindala ezazivamile futhi ezingahlangabezani namakhodi amanje. Ubudala buphinde bukhulise amathuba okungcoliswa kwamanzi angaphansi komhlaba angaphansi komhlaba alawulwa ngaphambilini embonini, okungaba yingozi, ikakhulukazi uma kuhlanganiswa nokuwohloka kwamapayipi angaphansi komhlaba okuhlobene nobudala.
Uma umndeni wakho uphuza amanzi ahlanzekile angaphezu kwamagaloni amabili kuya kwamathathu ngosuku, isihlungi samanzi esingaphansi kwesinki singaba inketho engcono kunesihlungi sejagi. Uhlelo lwesinki olungaphansi kwesinki luhlinzeka ngamanzi okuphuza ahlungiwe uma kudingeka ngaphandle kokulinda inqubo yokuhlunga ukuthi iphele, njengethangi lamanzi. Ukuhlunga "uma kudingeka" kusho nokuthi uhlelo lwesinki olungangaphansi kwesinki lunganikeza amanzi anele okupheka - isibonelo, ungagcwalisa imbiza ngamanzi ahlungiwe ukupheka i-pasta, kodwa awusoze waphinda wagcwalisa imbiza ngalokho.
Izihlungi ezingaphansi kwesinki nazo zivame ukuba nomthamo ophakeme kakhulu kanye nokuphila isikhathi eside kunezihlungi ze-canister—ngokuvamile amakhulu amagaloni nezinyanga eziyisithupha noma ngaphezulu, uma kuqhathaniswa namagaloni angu-40 namagaloni angu-40 ezihlungini eziningi ze-canister. izinyanga ezimbili. Futhi ngenxa yokuthi izihlungi ezingaphansi kwesinki zisebenzisa umfutho wamanzi esikhundleni samandla adonsela phansi ukuze zicindezele amanzi esihlungini, izihlungi zazo zingaba nzima kakhulu, ngakho-ke zingasusa uhla olubanzi lwezinto ezingaba khona ezingcolisayo.
Ngakolunye uhlangothi, zibiza kakhulu kunezihlungi ze-pitcher, kanti ukufakelwa kwezihlungi nakho kubiza kakhulu ngokwezinga eliphelele kanye nesilinganiso ngokuhamba kwesikhathi. Uhlelo luphinde luthathe isikhala ekhabetheni lesinki ebelingatholakala ukuze ligcinwe.
Ukufaka isihlungi esingaphansi kwesinki kudinga ukufakwa kwamapayipi kanye nehadiwe okuyisisekelo, kodwa umsebenzi olula kuphela uma isinki yakho isivele inomgodi owodwa wompompi. Uma kungenjalo, kuzodingeka ukhiphe enye yezindawo zompompi ezakhelwe ngaphakathi (ezibonakala njengamadiski aphakanyisiwe kumasinki ensimbi, noma amamaki kumasinki amatshe okwenziwa). Ngaphandle kokugoba, kuzodingeka ubhoboze imbobo kusinki, futhi uma isinki yakho ingaphansi kwekhawunta, kuzodingeka futhi ubhoboze imbobo kukhawunta. Uma okwamanje une-dispenser yensipho, igebe lomoya womshini wokuwasha izitsha, noma i-sprayer ephathwayo kusinki, ungayisusa bese ufaka impompi lapho.
Lezi zihlungi zamanzi, amathangi kanye nezihlinzeki zamanzi ziqinisekiswe ukususa ukungcola nokuthuthukisa amanzi okuphuza asekhaya.
Lo mhlahlandlela umayelana nohlobo oluthile lwesihlungi esingaphansi kwesinki: lezo ezisebenzisa isihlungi sekhatriji futhi zithumela amanzi ahlungiwe kumpompi ohlukile. Lezi yizihlungi ezithandwa kakhulu ezingaphansi kwesinki. Zithatha isikhala esincane 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. Asikhulumi ngezihlungi ezifakwe empompini, izinhlelo ze-reverse osmosis, noma amanye amathangi noma izihlinzeki.
Ukuqinisekisa ukuthi sincoma kuphela izihlungi ongazethemba, sigcizelele ukuthi ukukhetha kwethu kuqinisekiswe ngokwezinga lomkhakha: i-ANSI/NSF. I-American National Standards Institute kanye ne-NSF International ziyizinhlangano ezizimele, ezingenzi nzuzo ezisebenzisana ne-EPA, abameleli bemboni kanye nabanye ochwepheshe ukuthuthukisa amazinga aqinile ekhwalithi kanye nezinqubo zokuhlola izinkulungwane zemikhiqizo, kufaka phakathi izihlungi zamanzi. Amalabhorethri amabili aqashelwe kakhulu ezihlungi zamanzi yi-NSF International uqobo kanye ne-Water Quality Association (WQA). Zombili ziqinisekiswe ngokugcwele eNyakatho Melika yi-ANSI kanye ne-Standards Council of Canada yokuhlolwa kokugunyazwa kwe-ANSI/NSF, futhi zombili kumele zilandele amazinga kanye nezinqubo zokuhlola ezifanayo. Izihlungi azihlangabezani nezindinganiso zesitifiketi kuze kube yilapho isikhathi sazo sokuphila esilindelekile, zisebenzisa amasampula "enselele" alungisiwe angcoliswe kakhulu kunamanzi amaningi ompompi.
Kulo mhlahlandlela, sigxila ezihlungini ezinezitifiketi ze-chlorine, i-lead, kanye ne-VOC (eyaziwa nangokuthi ama-volatile organic compounds).
Isitifiketi se-chlorine (ngokusho kwe-ANSI/Standard 42) sibalulekile ngoba i-chlorine ivame ukuba yimbangela “yokunambitheka okubi” kwamanzi ompompi. Kodwa futhi kuyinto enhle kakhulu: Cishe zonke izinhlobo zezihlungi zamanzi ziqinisekisiwe.
Isitifiketi sokuhola kunzima ukusithola ngoba kusho ukunciphisa izixazululo ezicebile nge-lead ngamaphesenti angaphezu kuka-99%.
Isitifiketi se-VOC naso siyinselele, njengoba kusho ukuthi isihlungi singasusa cishe amakhemikhali angaphezu kuka-50 e-organic, okuhlanganisa nemithi eminingi evame ukusetshenziswa e-biocides kanye nezinto ezisetshenziswa ezimbonini. Akuzona zonke izihlungi ezingaphansi kwesinki ezinezitifiketi zombili, ngakho-ke ngokugxila kuzihlungi ezinezitifiketi zombili, sithole lezo ezisebenza kangcono kakhulu.
Sinciphise usesho lwethu ukuze sikhethe izihlungi eziqinisekiswe yi-ANSI/NSF Standard 401 entsha, ehlanganisa inani elikhulayo lezinto ezingcolisayo ezivela emanzini ase-US, njengemithi. Futhi, akuzona zonke izihlungi ezinesitifiketi se-401, ngakho lezo ezinaso (kanye nezitifiketi ze-lead kanye ne-VOC) ziyiqembu elikhethiwe kakhulu.
Ngaphakathi kwalesi sigaba esiqinile, sibheka lezo ezinomthamo omncane wamagalani angu-500. Lokhu kulingana nokuphila kwesihlungi okungaba yizinyanga eziyisithupha ngokusetshenziswa kakhulu (amagalani angu-2¾ ngosuku). Emindenini eminingi, lawa amanzi ahlungiwe anele okuphuza nokupheka nsuku zonke. (Abakhiqizi banikeza amashejuli okushintsha isihlungi anconywayo, ngokuvamile alinganiswa ngezinyanga kunamagalani; silandela lezi zincomo ekuhlolweni kwethu kanye nokubala izindleko. Sincoma njalo ukusebenzisa izihlungi zomkhiqizi wokuqala, hhayi izihlungi zenkampani yangaphandle.)
Ekugcineni, silinganise izindleko zaso sonke isimiso kusengaphambili ngezindleko eziqhubekayo zokushintsha isihlungi. Asizange sibeke intengo phansi noma ophahleni, kodwa ucwaningo lwethu lukhombisile ukuthi yize izindleko zaso ziqala ku-$100 kuya ku-$1,250 kanti izindleko zesihlungi ziqala ku-$60 kuya cishe ku-$300, lo mehluko awuzange ubonakale kumodeli ebiza kakhulu ecacile kuma-specs. Sithole izihlungi eziningana ezingaphansi kwesinki ngaphansi kuka-$200 ngenkathi sinikeza isitifiketi esihle kakhulu kanye nokuphila isikhathi eside. Laba baba ngabaphumelele kowamanqamu. Ngaphezu kwalokhu, sibheka futhi:
Ngesikhathi socwaningo lwethu, ngezinye izikhathi sihlangane nemibiko yokuvuza okubi okuvela kubanikazi bezihlungi zamanzi ezingaphansi kwesinki. Njengoba isihlungi sinamathele emgqeni wokungena kwamanzi abandayo, uma isixhumi noma ipayipi liphuka, amanzi azophuma kuze kube yilapho ivalvu yokuvala ivala - okusho ukuthi kungathatha amahora noma ngisho nezinsuku ukuthi uthole inkinga, kube nemiphumela emibi ngomonakalo wakho wamanzi. Lokhu akuvamile, kodwa kunezingozi okufanele uzicabangele lapho ucabanga ukuthenga isihlungi esingaphansi kwesinki. Uma uthenga esisodwa, landela imiyalelo yokufaka ngokucophelela, uqaphele ukuthi ungasicindezeli isixhumi, bese uvula amanzi kancane kancane ukuze uhlole ukuvuza.
Isihlungi se-reverse osmosis noma i-R/O siqala ngohlobo olufanayo lwesihlungi se-cartridge esisikhethile lapha, kodwa senezela indlela yesibili yokuhlunga i-reverse osmosis: ulwelwesi olunezimbobo ezincane oluvumela amanzi ukuthi adlule kodwa luhlunge izinto zamaminerali ezincibilikisiwe nezinye izinto.
Singase sixoxe ngokujulile ngezihlungi ze-R/O esiqondisweni esizayo. Lapha siyazenqaba ngokuphelele. Zinezinzuzo ezilinganiselwe zokusebenza ngaphezu kwezihlungi zokumunca; zikhiqiza amanzi amaningi angcolile (ngokuvamile zihlunga amalitha angu-4 amanzi “angcolile” ngegaloni ngalinye), kuyilapho izihlungi zokumunca zingakhiqizi amanzi angcolile; zithatha isikhala esiningi, ngoba ngokungafani nezihlungi zokumunca, zisebenzisa ithangi elingamagaloni angu-1 noma angu-2 ukugcina amanzi ahlungiwe; zihamba kancane kakhulu kunezihlungi zokumunca ezingaphansi kwesinki.
Senze izivivinyo zelebhu ezihlungini zamanzi eminyakeni embalwa edlule, futhi into esiyifundile ekuhlolweni kwethu ukuthi isitifiketi se-ANSI/NSF siyisilinganiso esithembekile sokusebenza kwezihlungi. Lokhu akumangazi uma ubheka ubunzima obukhulu bokuhlolwa kwezitifiketi. Kusukela ngaleso sikhathi, sithembele esiqinisekisweni se-ANSI/NSF kunokuhlola kwethu okulinganiselwe ukuze sikhethe abancintisana nathi.
Ngo-2018, sahlola uhlelo lokuhlunga amanzi oludumile lweBig Berkey, olungaqinisekisiwe yi-ANSI/NSF, kodwa oluthi luhlolwe kabanzi ngezindinganiso ze-ANSI/NSF. Lokhu okuhlangenwe nakho kwaqinisa ukuphikelela kwethu ekuqinisekisweni kwe-ANSI/NSF kwangempela kanye nokungathembi kwethu isimangalo esithi “ANSI/NSF Tested”.
Kusukela ngaleso sikhathi, nango-2019, ukuhlola kwethu kugxile ekusebenziseni kwangempela kanye nezinhlobo zezici eziwusizo kanye nokungalungi okubonakala njengoba usebenzisa le mikhiqizo.
Iqinisekiswe yizinto eziningi ezingcolisayo, ezitholakala kabanzi, ezingabizi, futhi ezincane, i-Aquasana AQ-5200 iyisistimu yokuqala yokuhlunga amanzi ngaphansi kwesinki esiyifunayo.
Isinqumo sethu yi-Aquasana AQ-5200, eyaziwa nangokuthi i-Aquasana Claryum Dual-Stage. Isici sayo esibaluleke kakhulu kuze kube manje ukuthi izihlungi zayo zinezitifiketi ze-ANSI/NSF ezinhle kakhulu zabancintisana nathi, okuhlanganisa i-chlorine, i-chloramines, i-lead, i-mercury, ama-VOC, "izinto ezingcolisayo eziphumayo" eziningi kanye ne-PFOA kanye ne-PFOS. Ngaphandle kwalokho, i-faucet yayo kanye ne-plumbing hardware yenziwe ngensimbi eqinile, engcono kunepulasitiki esetshenziswa abanye abakhiqizi. Futhi uhlelo luphinde lube ncane kakhulu. Okokugcina, i-Aquasana AQ-5200 ingenye yamanani amahle kakhulu esiwatholile kuzihlungi ezingaphansi kwesinki, izindleko zangaphambili zesistimu yonke (isihlungi, indlu, i-faucet, kanye ne-hardware) ngokuvamile zicishe zibe ngu-$140 kusengaphambili, kanti isethi yezimbili ibiza u-$60 ukuze ithathe indawo yesihlungi. Lokho kungaphansi kwabancintisana abaningi abanezitifiketi ezibuthakathaka.
I-Aquasana AQ-5200 iqinisekiswe yi-ANSI/NSF (PDF) ukuthola ukungcola okungu-77. Kanye ne-Aquasana AQ-5300+ eqinisekisiwe efanayo kanye ne-AO Smith AO-US-200, lokhu kwenza i-AQ-5200 ibe uhlelo oluqine kakhulu oluqinisekisiwe esilukhethile. (I-AO Smith yathenga i-Aquasana ngo-2016 futhi yamukela ubuchwepheshe bayo obuningi; i-AO Smith ayinazo izinhlelo zokuqeda umugqa womkhiqizo we-Aquasana.) Ngokuphambene nalokho, isihlungi se-Pur Pitcher esihle kakhulu esinokunciphisa i-lead sinesitifiketi esingu-23.
Lezi zitifiketi zifaka phakathi i-chlorine, esetshenziselwa ukubulala amagciwane ezindaweni zamanzi zikamasipala futhi iyimbangela ehamba phambili “yokunambitheka okubi” emanzini ompompi; i-lead, ephuma emapayipini amadala kanye ne-plumbing solder; i-mercury; i-Cryptosporidium ephilayo kanye ne-Giardia flagellates, amagciwane amabili angaba khona; kanye ne-chloramine, isibulala-magciwane se-chloramine esiqhubekayo esisetshenziswa kakhulu yizitshalo zokuhlunga eningizimu ye-United States, i-chlorine emsulwa ewohloka ngokushesha emanzini afudumele. I-Aquasana AQ-5200 nayo iqinisekisiwe ngenani elikhulayo “lezinto ezingcolisayo ezivelayo” ezingu-15 ezinhlelweni zamanzi zomphakathi, kufaka phakathi i-BPA, i-ibuprofen, kanye ne-estrone (i-estrogen esetshenziswa ekulawuleni inzalo); ye-PFOA kanye ne-PFOS— — Amakhemikhali asekelwe ku-fluorine asetshenziselwa ukwenza izinto ezinganamatheli futhi athole iseluleko sezempilo se-EPA ngoFebhuwari 2019. (Ngesikhathi sokubonisana, abakhiqizi abathathu kuphela bezihlungi ezinjalo abaqinisekiswe yi-PFOA/S, okwenza lokhu kuphawuleke kakhulu.) Iqinisekiswe futhi yi-VOC. Lokhu kusho ukuthi ingasusa ngempumelelo amakhemikhali angaphezu kuka-50 ahlukene e-organic, kufaka phakathi izibulala-zinambuzane eziningi kanye nezinto ezisetshenziswa ezimbonini.
Ngaphezu kwama-resin okushintshana ngekhabhoni esebenzayo kanye nama-ion (izihlungi ezivamile uma kungezona zonke ezingaphansi kwesinki), i-Aquasana isebenzisa ubuchwepheshe obubili bokuhlunga ukuze ithole isitifiketi. Kuma-chloramine, ingeza ikhabhoni evuselelayo, ikhabhoni evuselelayo enezimbobo futhi ngenxa yalokho esabela kakhulu ekhiqizwa ngokwelapha ikhabhoni ngegesi lokushisa eliphezulu. Ku-Cryptosporidium kanye ne-Giardia, i-Aquasana yenza isihlungi ngokunciphisa usayizi wembobo ube yi-0.5 microns, encane ngokwanele ukubamba ngokomzimba.
Isitifiketi esiphezulu sesihlungi se-Aquasana AQ-5200 yisona sizathu esiyinhloko esasenza sakhetha sona. Kodwa ukwakheka kwaso nezinto zaso nakho kuyasihlukanisa. Impompi yenziwe ngensimbi eqinile, njengoba kunjalo ngama-T-clamp axhumanisa isihlungi nepayipi. Abanye abancintisana nabo basebenzisa ipulasitiki kokukodwa noma kokubili, okunciphisa izindleko kodwa kwandisa ingozi yokuhlanganisa intambo kanye nokufakwa okungalungile. I-AQ-5200 isebenzisa izinto zokucindezela ukuqinisekisa ukuvalwa okuqinile nokuvikelekile phakathi kwepayipi kanye nepayipi lepulasitiki elithwala amanzi liye kusihlungi kanye nepayipi; abanye abancintisana nabo basebenzisa izinto zokucindezela ezilula, ezingavikelekile kakhulu. Ipompo ye-AQ-5200 itholakala ngezinhlobo ezintathu zokuqeda (i-nickel ebhulashiwe, i-chrome epholishiwe, kanye nethusi eligcotshwe ngamafutha), kuyilapho abanye abancintisana nabo bengenakukhetha.
Sithanda futhi uhlobo oluncane lwesistimu ye-AQ-5200. Isebenzisa izihlungi ezimbili, ngasinye sikhulu kancane kunethini likasoda; ezinye, okuhlanganisa ne-Aquasana AQ-5300+ ngezansi, zilingana nebhodlela elilitha. Njengoba isihlungi sifakwe ebhulokini lokufaka, i-AQ-5200 inobude obungamasentimitha angu-9, ububanzi obungamasentimitha angu-8, kanye nokujula okungamasentimitha angu-4; i-Aquasana AQ-5300+ inobude obungamasentimitha angu-13 x 12 x 4. Lokhu kusho ukuthi i-AQ-5200 ithatha isikhala esincane kakhulu kukhabhinethi yesinki, ingafakwa ezindaweni eziqinile lapho izinhlelo ezinkulu zingenakungena khona, futhi ishiya isikhala esengeziwe sokugcina ngaphansi kwesinki. Udinga cishe amasentimitha angu-11 esikhala esiqondile (esilinganiswa phansi kusukela phezulu kwesinki) ukuze uvumele ukushintshwa kwesihlungi, kanye namasentimitha angu-9 esikhala esivundlile esingavimbeki odongeni lwekhabhinethi ukuze ufake isinki.
I-AQ-5200 ilinganiswe kahle kakhulu ngezihlungi zamanzi, ithola ukubuyekezwa okungu-4.5 kwabahlanu kwabangu-800 kuwebhusayithi ye-Aquasana kanye nokubuyekezwa okungu-4.5 kwabacishe babe ngu-500 kwa-Home Depot.
Okokugcina, intengo yamanje yesistimu ephelele ye-Aquasana AQ-5200 icishe ibe ngu-$140 (ngokuvamile ithengiswa cishe ngo-$100) kanye no-$60 ngesethi yezihlungi zokufaka esikhundleni ($120 ngonyaka ngomjikelezo wokufaka esikhundleni wezinyanga eziyi-6), i-Aquasana AQ-5200 ingenye yamanani amahle kakhulu phakathi kwabancintisana nathi futhi ishibhile ngamadola amaningi kunamanye amamodeli anezitifiketi ezincane. Le yunithi ifaka isibali sikhathi esizoqala ukukhala uma udinga ukushintsha isihlungi, kodwa sincoma ukusetha isikhumbuzi sekhalenda esiphindaphindayo efonini yakho. (Akunakwenzeka ukuthi usiphuthelwe.)

Lokhu kungumphumela oqondile wesihlungi sayo esincane ngokomzimba. Sekukonke, sicabanga ukuthi la maphutha amancane adlula ukuqina kwayo. Uma wazi ukuthi udinga ukugeleza okuphezulu kanye nomthamo, i-Aquasana AQ-5300+ ikalwe ku-0.72 gpm kanye namagaloni angu-800, kodwa ngesheduli efanayo yokushintsha isihlungi yezinyanga eziyisithupha, i-Aquasana Clarium Direct Connect inikeza izilinganiso ezifika ku-1.5 gpm Ukugeleza kuya kumagaloni angu-784 nezinyanga eziyisithupha.
