Sihlola ngokuzimela yonke into esiyincomayo. Uma uthenga ngezixhumanisi zethu, singase sizuze ikhomishini. Thola okwengeziwe>
I-Amazon's October Sale iyaqhubeka. Ukuze uthole amadili e-Wirecutter amaningi okufanele uwathenge, hlola uhlu lwethu lwamadili angcono kakhulu e-Prime Day.
Noma ubani ophuza ngaphezu kwamalitha ambalwa amanzi okuphuza ngosuku cishe uzoneliseka kakhulu ngesistimu yokuhlunga engaphansi kwe-sink njenge-Aquasana AQ-5200. Ngokungafani nojeke, isihlungi esingaphansi kukasinki sinikeza ukutholakala kwamanzi okuqhubekayo lapho kudingeka. Sincoma i-Aquasana AQ-5200 ngoba izitifiketi zayo zingcono kakhulu kunoma iyiphi isistimu esiyitholile; zihlanganisa (njengezinye izixazululo zethu lapha) i-chlorine, i-lead, i-mercury, i-PFAS, izinhlobonhlobo zezibulala-zinambuzane, nama-microplastics.
I-Aquasana AQ-5200 iyisitifiketi se-ANSI/NSF futhi ingaqeda ukungcola okuhlukahlukene, okuhlanganisa umthofu, i-mercury, izibulala-zinambuzane, ama-microplastics, imithi kanye nezinye izinto ezimbalwa izimbangi ezingabamba. Kungesinye sezihlungi ezimbalwa eziqinisekisiwe ukuthi ziqukethe i-PFOA ne-PFOS, amakhemikhali amabili aphikelelayo akhathaza i-Environmental Protection Agency.
Izindleko zokushintsha isethi yezihlungi zingaba ngu-$60, noma u-$120 ngonyaka, ngokusekelwe kumjikelezo onconyiwe we-Aquasana wokubuyisela wezinyanga eziyisithupha. Futhi isistimu ingaphezudlwana nje kwamathini ambalwa esoda, ngakho ayithathi isikhala esiningi esibalulekile ngaphansi kukasinki. Ifaka ukufakwa kwensimbi kwekhwalithi ephezulu futhi ompompi batholakala ngezinhlobonhlobo zokuqeda.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 kuzo zonke izici ezibalulekile. (Lokho kungenxa yokuthi i-AO Smith ithole i-Aquasana ngo-2016.) Inezici ezifanayo ze-premium, i-hardware yensimbi yonke, kanye ne-compact form factor, kodwa njengoba ithengiswa kuphela kwa-Lowe, ayitholakali kakhulu futhi izimpompi zayo zinesiphelo esisodwa kuphela. : nickel ebhulashiwe. Izindleko zokushintsha izihlungi ziyefana: cishe u-$60 isethi ngayinye, noma u-$120 ngonyaka emjikelezweni wezinyanga eziyisithupha otuswe ngu-AO Smith.
Inezitifiketi ezinhle kakhulu ezifana ne-AQ-5200, kanye nekhono eliphezulu lokugeleza namandla okuhlunga kune-AQ-5200, kanye nesihlungi sangaphambilini sokususa amadiphozithi okugqwala.
I-Aquasana AQ-5300+ Max Flow inezitifiketi ezinhle kakhulu njengokukhetha kwethu okuphezulu, kodwa inikeza ukugeleza okuphezulu (0.72 gpm vs. 0.5 gpm) kanye nomthamo wokuhlunga (800 gpm vs. 500). gpm). Lokhu kwenza kube inketho efanelekile emakhaya adinga amanzi amaningi ahlungiwe futhi awafune ngokushesha ngangokunokwenzeka. Futhi yengeza isihlungi sangaphambili se-sediment i-AQ-5200 engenaso; lokhu kunganweba isihlungi esingcolile ngamanani aphezulu okugeleza ezindlini ezinamanzi anothile ngenhlabathi. Kodwa-ke, i-AQ-5300+ (enezihlungi usayizi webhodlela lamalitha amathathu) inkulu kakhulu kune-AQ-5200, futhi izindleko zokushintshwa kokuqala nezihlungi ziphakeme kancane (cishe ama-dollar angu-80 isethi ngayinye noma i-$ 160 ngonyaka). .
Ifaka ngaphandle kokubhoboza futhi ilethe amalitha angu-1.5 ngomzuzu wamanzi ahlungiwe ngompompi abakhona.
I-Claryum Direct Connect ye-Aquasana ixhuma ngqo koompompi abakhona, okuyenza ibe inketho ekhangayo ngokukhethekile kubaqashi (abangase bavinjelwe ukuhamba) nalabo abangakwazi ukufaka impompi yesihlungi ehlukile. Akudingeki ukuthi ifakwe odongeni lwekhabethe ngaphansi kukasinki, ivele ime ngohlangothi. Inezitifiketi ezifanayo ze-ANSI/NSF njengezinye izinhlobo ze-Aquasana ne-AO Smith futhi ingaletha amalitha angu-1.5 amanzi ahlungiwe ngomzuzu. Lesi sihlungi sinomthamo olinganiselwe wamalitha angu-784 futhi kufanele sithathe cishe izinyanga eziyisithupha. Kodwa ayinaso isihlungi sangaphambili se-sediment. Ngakho-ke, uma unezinkinga nge-sediment, lena akuyona inketho engcono kakhulu njengoba ingavala kalula. Futhi inkulu—20.5 x 4.5 amayintshi—ngakho uma ikhabethe lakho likasinki lilincane noma liminyene, lingase lingalingani.
Inezitifiketi ezinhle kakhulu ezifana ne-AQ-5200, kanye nekhono eliphezulu lokugeleza namandla okuhlunga kune-AQ-5200, kanye nesihlungi sangaphambilini sokususa amadiphozithi okugqwala.
Ifaka ngaphandle kokubhoboza futhi ilethe amalitha angu-1.5 ngomzuzu wamanzi ahlungiwe ngompompi abakhona.
Bengilokhu ngihlola izihlungi zamanzi ze-Wirecutter kusukela ngo-2016. Embikweni wami, ngikhulume kabanzi nezinhlangano zokuqinisekisa izihlungi ukuze ngiqonde ukuthi ukuhlola kwazo kwenziwa kanjani, futhi ngajula kusizindalwazi sazo somphakathi ukuze ngiqinisekise ukuthi izimangalo zabakhiqizi zisekelwa: Ukuhlola okuqinisekisiwe. . Ngiphinde ngakhuluma nabamele abakhiqizi abambalwa bokuhlunga amanzi, okuhlanganisa i-Aquasana/AO Smith, i-Filtrete, i-Brita ne-Pur, ukuphikisa izimangalo zabo. Ngizamile mathupha zonke izinketho zethu ngoba ukwethembeka kukonke, ukuqina, nokusebenziseka kubaluleke kakhulu kudivayisi esetshenziswa izikhathi ezimbalwa ngosuku.
Owayengusosayensi we-NOAA uJohn Holecek ucwaninge futhi wabhala incwadi yokuqala yesihlungi samanzi e-Wirecutter, wazihlola ngokwakhe, wagunyaza ukuhlolwa okwengeziwe okuzimele, futhi wangifundisa okuningi engikwaziyo. Umsebenzi wami usekelwe emsebenzini wakhe.
Ngeshwa, ayikho impendulo yendawo yonke embuzweni wokuthi udinga isihlungi samanzi noma cha. E-United States, amanzi omphakathi alawulwa yi-US Environmental Protection Agency ngaphansi koMthetho Wamanzi Ahlanzekile, futhi izindawo zokuhlanza amanzi zomphakathi eziphuma emanzini kufanele zihlangabezane nezindinganiso eziqinile zekhwalithi. Kodwa akuzona zonke izinto ezingase zibe ukungcola ezilawulwayo. Ukwengeza, ukungcola kungangena emanzini ngemva kokuba ephumile endaweni yokuhlanza, kungaba ngamapayipi avuzayo (PDF) noma ngokuvuza emapayipini ngokwawo. Ukuhlanzwa kwamanzi okwenziwa (noma ukunganakwa) esitshalweni kungabhebhethekisa ukugeleza kwamapayipi angezansi komfula, njengoba kwenzeka e-Flint, Michigan.
Ukuze uthole ukuthi yini ngempela emanzini omphakeli wakho, ungakwazi ukusesha ku-inthanethi umbiko wokuthenjwa komthengi wendawo womphakeli wakho wasendaweni we-EPA; ngaphandle kwalokho, bonke abaphakeli bamanzi bomphakathi kudingeka ukuthi bakunikeze ama-CCR abo uma ucela. Kodwa ngenxa yokungcola okungaba khona ezansi nomfula, okuwukuphela kwendlela yokunquma ukuthi yini esemanzini endlu yakho ukukhokha ilebhu yendawo yekhwalithi yamanzi ukuze iwahlole.
Njengomthetho ojwayelekile, lapho ikhaya lakho noma indawo yakini indala, iba nkulu ingozi yokungcoliswa komfula. I-Environmental Protection Agency ibika ukuthi “izindlu ezakhiwa ngaphambi kuka-1986 zinamathuba amaningi okuba namapayipi omthofu, izinto ezisetshenziswayo kanye nezinsimbi”—izinto ezindala, ezake zavamile ezingawahlanganisi amakhodi amanje. Iminyaka yobudala iphinde inyuse amathuba okungcoliswa kwamanzi angaphansi komhlaba asekhulile yizimboni ezilawulwa ngaphambilini, ezingaba yingozi, ikakhulukazi uma kuhlanganiswa nokucekelwa phansi okuhlobene neminyaka yamapayipi angaphansi komhlaba.
Uma umndeni wakho usebenzisa amanzi okuphuza angaphezu kwamalitha amabili kuya kwamathathu ngosuku, isihlungi samanzi esingaphansi kukasinki singase sibe yisinqumo esingcono kunesisefo sembiza. Amasistimu angaphansi kukasinki aletha amanzi okuphuza ahlungiwe lapho efunwa, okuqeda isidingo sokulinda inqubo yokuhlunga iphele njengokungathi ngembiza. Ukuhlunga okufunwayo kuphinde kusho ukuthi uhlelo olungaphansi kwe-sink lunganikeza amanzi anele okupheka-isibonelo, ungagcwalisa ibhodwe ngamanzi ahlungiwe ukupheka i-pasta, kodwa awusoze waphinda ugcwalise i-pitcher ngaleyo njongo. .
Uma kuqhathaniswa nezihlungi ze-pitcher, izihlungi ezingaphansi kukasinki zivame ukuba nomthamo omkhulu nempilo ende-imvamisa amamalitha angamakhulu ambalwa nezinyanga eziyisithupha noma ngaphezulu uma kuqhathaniswa nosayizi wamalitha angama-40 wezihlungi eziningi ze-pitcher nezinyanga ezimbili. Ngenxa yokuthi izihlungi ezingaphansi kukasinki zisebenzisa umfutho wamanzi kunokuba amandla adonsela phansi asunduze amanzi ngesihlungi, izihlungi zazo zingaba ziminyene futhi ngenxa yalokho zisuse uhla olubanzi lwezinto ezingaba ukungcola.
Okubi ukuthi zibiza kakhulu ngaphambili kunezihlungi ze-pitcher, futhi izihlungi ezishintshayo nazo zibiza kakhulu ngokwemibandela ephelele nangesilinganiso ngokuhamba kwesikhathi. Uhlelo luphinde luthathe isikhala sekhabhinethi ngaphansi kukasinki obengase usetshenziselwe ukulondoloza.
Ukufaka isihlungi esingaphansi kukasinki kudinga ukufakwa kwamapayipi okuyisisekelo kanye nezingxenyekazi zekhompuyutha, kodwa umsebenzi ulula kuphela uma usinki wakho usuvele unendawo yokuvula impompi ehlukile. Uma kungenjalo, kuzodingeka ukuthi ususe enye yezindawo zikampompi owakhelwe ngaphakathi (idiski eliphakanyisiwe kusinki wensimbi noma umaka kusinki wamatshe wokwenziwa). Uma ungenayo imbobo yokukhipha, kuzodingeka ubhoboze imbobo kusinki noma ku-countertop uma usinki wakho wehlisiwe. Uma unomshini wokukhipha insipho noma isifafazi sesandla kusinki wakho, ungawususa bese ufake umpompi. (Ungawufaki umpompi lapho kunegebe lomoya - lokhu ukuvikela amanzi okugeza angcolile ukuthi angangeni emshinini wokuwasha izitsha.)
Cishe ingxenye yawo wonke amanzi kampompi anamakhemikhali aphikelelayo. Nansi indlela yokunquma ukuthi usengozini futhi ukhawulele ukuchayeka kwakho.
Lo mhlahlandlela umayelana nohlobo oluthile lwesihlungi esingaphansi kukasinki: lezo ezisebenzisa isihlungi se-cartridge. Zithatha indawo encane kakhulu futhi ngokuvamile kulula ukuzifaka nokuyinakekela. Basebenzisa izinto ze-adsorbent (imvamisa i-carbon ecushiwe nama-ion exchange resins njengezihlungi ze-pitcher) ukuze babophe futhi banciphise ukungcola. Iningi likhuphukela kumpompi ohlukile (ofakiwe), okusho ukuthi uzodinga imbobo efakwa ku-countertop; Imbobo eyenzelwe ipayipi lokufutha izosebenza, noma ungabhoboza imbobo entsha. Asikhulumi ngezihlungi ze-faucet-mount, amasistimu we-osmosis ahlehlayo, noma ezinye izimbiza zamanzi noma iziphakeli.
Ukuqinisekisa ukuthi sincoma kuphela izihlungi ongazethemba, sihlala sigcizelela ukuthi ukukhetha kwethu kugunyazwe ngezinga lomkhakha: ANSI/NSF. I-American National Standards Institute kanye ne-NSF International yizinhlangano ezizimele, ezingenzi nzuzo ezisebenza ne-Environmental Protection Agency, imboni kanye nabanye ochwepheshe ukuthuthukisa amazinga aqinile ekhwalithi nezinqubo zokuhlola zezinkulungwane zemikhiqizo, okuhlanganisa nezihlungi zamanzi. Amalabhorethri amabili ayinhloko wokunikeza izitifiketi zokuhlunga amanzi yi-NSF International ngokwayo kanye neNhlangano Yekhwalithi Yamanzi (WQA). Yomibili le mikhiqizo igunyazwe ngokugcwele yi-ANSI kanye noMkhandlu Wamazinga WaseCanada eNyakatho Melika ngokuhlolwa kwesitifiketi se-ANSI/NSF, futhi yomibili kufanele ihambisane namazinga afanayo nezinqubo zokuhlola. Kuphela ngemva kokusebenzisa amasampula “okuhlola” alungisiwe, ayengcoliswe kakhulu kunamanzi amaningi kampompi, lapho isihlungi sahlala khona ngaphezu kwempilo eyayilindelwe futhi sahlangabezana nezindinganiso zokunikeza isitifiketi.
Kulo mhlahlandlela, sizogxila kuzihlungi ezigunyazwe i-chlorine, i-lead, ne-volatile organic compounds (VOCs).
Ukuqinisekiswa kwe-chlorine kubalulekile ngoba i-chlorine iyicala elivamile "ephunga elibi" emanzini kampompi. Kodwa lokhu cishe kuyisibusiso: cishe zonke izinhlobo zokuhlunga amanzi ziqinisekisiwe.
Ukuthola isitifiketi somthofu kunzima ngoba kusho ukwehlisa izixazululo ezinothile ngomthofu ngaphezu kwama-99%.
Ukuqinisekiswa kwe-VOC nakho kuyinselele ngoba kusho ukuthi isihlungi empeleni singasusa izinhlanganisela eziphilayo ezingaphezu kuka-50, okuhlanganisa ama-biocides amaningi avamile kanye nezandulela zezimboni. Akuzona zonke izihlungi ezingaphansi kukasinki ezinezitifiketi zombili, ngakho ngokugxila kuzihlungi ezinazo zombili izitifiketi, sihlonze izihlungi ezenza kangcono kakhulu.
Sinciphise usesho lwethu ngokuqhubekayo futhi sakhetha izihlungi ezinezitifiketi ezengeziwe ezingeni elisha ngokuqhathaniswa le-ANSI/NSF 401, elimboza ukungcola okuvelayo okutholakala ngokwandayo emanzini e-United States, njengemithi. Ngokufanayo, akuzona zonke izihlungi ezinezitifiketi ezingama-401. Ngakho-ke, lezo zikhungo eziqinisekisiwe ezingama-401 (kanye nomthofu kanye ne-VOC eqinisekisiwe) ziseqenjini elikhethwe ngokucophelela.
Bese-ke, ngaphakathi kwalesi siqeshana esiqinile, sibheka imikhiqizo enomthamo omncane wamamalitha angama-500. Lokhu kulingana cishe nezinyanga eziyisithupha zempilo yokuhlunga ngaphansi kokusetshenziswa kanzima (amalitha angu-2.75 ngosuku). La manzi ahlungiwe anele imindeni eminingi ukuphuza nokupheka nsuku zonke. (Abakhiqizi bahlinzeka ngamashejuli anconyiwe okushintsha izihlungi, ngokuvamile ngezinyanga kunamagalani; silandela lezi zincomo ezilinganisweni zethu nasezibalweni zezindleko. Sincoma ukuthi ngaso sonke isikhathi sisebenzise izingxenye zomkhiqizi zangempela esikhundleni sezihlungi zezinkampani zangaphandle.)
Ekugcineni, silinganise izindleko zokuqala zesistimu yonke ngokumelene nezindleko eziqhubekayo zokushintsha izihlungi. Asizange sibeke iphansi lentengo noma uphahla, kodwa ucwaningo lwethu lubonise ukuthi nakuba izindleko zokuqala zisukela ku-$100 kuya ku-$1,250 futhi izindleko zokuhlunga zisukela ku-$60 kuya cishe ku-$300, lo mehluko awuhumushelanga ekusebenzeni okuphakeme kakhulu. Amamodeli abiza kakhulu. Sithole izihlungi ezimbalwa ezingaphansi kukasinki ezibiza ngaphansi kuka-$200 kodwa zisenezitifiketi ezinhle kakhulu nokuqina. Laba ngabantu abagcine sebengowamanqamu. Phakathi kwezinye izinto esizifunayo:
Phakathi nocwaningo lwethu, ngezikhathi ezithile sasithola imibiko yokuvuza okuyinhlekelele kubanikazi bezihlungi zamanzi ezingaphansi kukasinki. Ngenxa yokuthi isihlungi sixhunywe kumthombo wamanzi abandayo, uma isixhumi noma ipayipi liphuka, amanzi angase avuze kuze kuvalwe ivalvu yokuvala, ngakho kungase kuthathe amahora noma izinsuku ukuthola inkinga, okuholela emiphumeleni emibi kuwe. Ukulimala kwamanzi. Akuvamile, kodwa uma ucabanga ukuthenga isihlungi esingaphansi kukasinki, udinga ukukala ubungozi. Uma uyithengile, landela imiyalelo yokuyifaka ngokucophelela, uqaphele ukuthi ungasonti izixhumi ngokungalungile, bese uvula amanzi kancane kancane ukuze uhlole ukuvuza. Ukuze uthole ukuthula kwengqondo okwengeziwe (ukuxazulula zonke izinkinga zakho zamapayipi amanzi, hhayi nje isihlungi esingaphansi kukasinki), cabanga ukufaka umtshina ovuzayo ohlakaniphile.
Izihlungi ze-Reverse Osmosis (R/O) ekuqaleni zinohlobo olufanayo lwesihlungi se-cartridge njengalesi esisikhethe lapha, kodwa sengeza indlela yokuhlunga ye-osmosis yesibili ehlehlayo: ulwelwesi olunombobo oluvumela amanzi ukuthi ludlule kodwa luhlunge amaminerali ancibilikisiwe nezinye izinto. . izinto.
Singase sixoxe ngezihlungi ze-R/O ngemininingwane eyengeziwe esifundweni esizayo. Lapha siyabenqaba ngokuphelele. Zinezinzuzo ezilinganiselwe zokusebenza ngaphezu kwezihlungi ze-adsorption; bakhiqiza inqwaba yamanzi angcolile (imvamisa amamalitha angu-4 amanzi angcolile "okugeza" ngegalani ngalinye elihlungiwe), kuyilapho izihlungi ze-adsorption zingakhiqizi amanzi angcolile; Bathatha indawo eyengeziwe ngoba, ngokungafani nezihlungi ze-adsorption, basebenzisa ithangi elingu-1 noma 2 galoni ukugcina amanzi ahlungiwe; futhi zisebenza kancane kakhulu kunezihlungi ze-adsorption ezingaphansi kukasinki.
Besihlola izihlungi zamanzi elabhorethri iminyaka eminingana edlule, futhi into eyinhloko esiyithatha ekuhlolweni kwethu ukuthi isitifiketi se-ANSI/NSF siyinkomba ethembekile yokusebenza kwesihlungi. Lokhu akumangazi uma kubhekwa ukuqina okwedlulele kokuhlolwa kwezitifiketi. Kusukela lapho, siye sathembela kusitifiketi se-ANSI/NSF ukuze sikhethe izimbangi esikhundleni sokuhlola kwethu okulinganiselwe.
Ngo-2018, sahlola isistimu yokuhlunga amanzi e-Big Berkey edumile, engaqinisekisiwe nge-ANSI/NSF kodwa ethi ihlolwe kakhulu ukuze ihlangabezane namazinga e-ANSI/NSF. Lokhu okwenziwayo kuphinde kwaqinisa ukuzibophezela kwethu ekutholeni isitifiketi se-ANSI/NSF sangempela kanye nokungathembani kwethu izimangalo “ze-ANSI/NSF Verified”.
Kusukela lapho, okuhlanganisa no-2019, ukuhlola kwethu kugxile ekusetshenzisweni komhlaba wangempela 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 ezihamba phambili ze-ANSI/NSF phakathi kwezimbangi zethu ze-chlorine, ama-chloramines, umthofu, i-mercury, ama-VOC, “izinto ezingcolisayo” eziningi ezivelayo, ama-microplastics, kanye ne-PFOA ne-PFOS. Ukwengeza, ompompi nezinto ezilungiswayo zenziwe ngensimbi eqinile, engcono kunepulasitiki esetshenziswa abanye abakhiqizi. Ngaphezu kwalokho, uhlelo luhlangene kakhulu. Ekugcineni, i-Aquasana AQ-5200 ingenye yezinketho ezingcono kakhulu esizitholile zokuhlunga ngaphansi kukasinki, nalo lonke uhlelo (isihlungi, izindlu, umpompi, nehadiwe) ngokuvamile kubiza cishe u-$140 ngaphambili noma isethi yokubili. ukushintshwa kwesihlungi nge-$60. Lokhu kungaphansi kwezimbangi eziningi ezinezitifiketi ezibuthakathaka.
I-ANSI/NSF Certification (PDF) ye-AQ-5200 Iqukethe i-chlorine, esetshenziselwa ukubulala amagciwane emanzini kamasipala futhi iyimbangela ehamba phambili “yokunganuki” emanzini kampompi; umthofu, ongaphuma kumapayipi amadala kanye ne-solder yamapayipi. ; i-mercury; I-Cryptosporidium ne-Giardia esebenzayo, amagciwane amabili angaba khona; I-Chloramine iyisibulala-magciwane esiphikelelayo se-chlorine-ammonia esisetshenziswa kakhulu ezitshalweni zokuhlunga eningizimu ye-United States. I-chlorine ehlanzekile ibola ngokushesha emanzini afudumele. I-AQ-5200 iphinde iqinisekiswe ngokumelene “nokungcola okuvelayo” okungu-15 okuvela ngokwandayo emanzini, okuhlanganisa i-BPA, ibuprofen ne-estrone (i-estrogen esetshenziswa ekulawuleni ukuzalwa), ama-microplastics, kanye ne-PFOA ne-PFOS, izinhlanganisela ezisekelwe ezimbonini ze-fluoride. itholakala kabanzi emanzini kampompi ase-US. Iphinde iqinisekiswe nge-VOC. Lokhu kusho ukuthi ingasusa ngempumelelo izinhlanganisela zezinto eziphilayo ezingaphezu kuka-50, okuhlanganisa izibulala-zinambuzane eziningi kanye nezandulela zezimboni.
Ngaphezu kwe-carbon ecushiwe ne-ion exchange resin (esetshenziswa ezihlungini eziningi ezingaphansi kukasinki), i-Aquasana isebenzisa ubuchwepheshe obubili bokuhlunga ukuze bathole isitifiketi. Kuma-chloramines, ikhabhoni ye-catalytic yengezwe, okungukuthi, ikhabhoni ecushiwe, enezimbotshana futhi esebenza kakhulu, eyenziwe ngokuphatha ikhabhoni ngegesi ephezulu yokushisa. Ku-cryptosporidium kanye ne-giardia, i-Aquasana ikhiqiza izihlungi ezinobukhulu bembobo obuncishisiwe bufika kuma-microns angu-0.5, amancane ngokwanele ukuba uwabambe ngokomzimba.
Ukuqinisekiswa kwesihlungi se-Aquasana AQ-5200 kwakuyisizathu esiyinhloko esisikhethile. Kodwa ukwakheka kwayo nezinto zokwakha nakho kuyayihlukanisa kwezinye. Umpompi wenziwe ngensimbi eqinile, kanjalo ne-T-piece exhuma isihlungi nepayipi. Abanye abancintisana nabo basebenzisa ipulasitiki eyodwa noma kokubili, okunciphisa izindleko kodwa kwandisa ingozi yokuwela izinkinobho nokufakwa okungalungile. I-AQ-5200 isebenzisa ukufakwa kokuminyanisa ukwenza isivalo esiqinile, esivikelekile phakathi kwepayipi neshubhu lepulasitiki elithwala amanzi liwayise kusihlungi nakumpompi. Abanye abancintisana nabo basebenzisa ukufakwa okulula, okungathembeki kangako. Isimpompi se-AQ-5200 sitholakala ngezinhlamvu ezintathu (i-nickel ebhulashiwe, i-chrome epholishiwe kanye nethusi elixutshwe ngamafutha), kanti abanye oqhudelana nabo bakushiye ungenakuzikhethela.
Siphinde sithanda i-compact form factor yohlelo lwe-AQ-5200. Isebenzisa ipheya lezihlungi, ngasinye sikhulu kancane kunekani likasoda; ezinye izihlungi, kufaka phakathi i-Aquasana AQ-5300+ ngezansi, zenzelwe amabhodlela amalitha. Ngesihlungi esifakwe kubakaki abakhwezwayo, i-AQ-5200 ikala amayintshi angu-9 ukuphakama, amayintshi angu-8 ububanzi, nama-intshi angu-4 ukushona; I-Aquasana AQ-5300+ ikala 13 x 12 x 4 amayintshi. Lokhu kusho ukuthi i-AQ-5200 ithatha isikhala sekhabethe esingaphansi kukasinki, esivumela ukuthi sifakwe ezindaweni eziqinile lapho amasistimu amakhulu engakwazi ukufakwa khona, okushiya indawo yokugcina engaphansi kukasinki. Uzodinga cishe amayintshi angu-11 esikhala esiqondile (esikalwe ukusuka phezulu kwekhabhinethi siye phansi) ukuze umiselele isihlungi kanye namayintshi acishe abe ngu-9 esikhala esivundlile samahhala eduze kwezindonga zekhabhinethi ukuze ufake ikhabethe.
I-AQ-5200 ithole ukubuyekezwa okuhle kakhulu njengesihlungi samanzi, izuza izinkanyezi ezingu-4.5 kwezingu-5 kwezingaphezu kuka-800 izibuyekezo kuwebhusayithi ye-Aquasana kanye nezinkanyezi ezingu-4.5 kuzibuyekezo ezicishe zibe ngu-500 e-Home Depot.
Okokugcina, ngentengo yamanje engaba ngu-$140 kulo lonke uhlelo (imvamisa intengo ilinganiselwa ku-$100) kanye no-$60 ngesethi yezihlungi ezishintshayo ($120 ngonyaka ngomjikelezo wokubuyisela wezinyanga eziyisithupha), i-Aquasana AQ-5200 iyilokho esiyikho. ngifuna isidingo. Enye yamadili angcono kakhulu emncintiswaneni kanye namakhulu amadola ashibhe kunamanye amamodeli anezitifiketi ezinde kancane. Idivayisi inesibali sikhathi esikhalayo uma udinga ukushintsha isihlungi, kodwa sincoma ukuthi futhi usethe izikhumbuzi zekhalenda ezivamile efonini yakho. (Akunakwenzeka ukuphuthelwa lokhu.)
Uma kuqhathaniswa nabanye oqhudelana nabo, i-Aquasana AQ-5200 inezinga lokugeleza eliphezulu eliphansi (0.5 gpm vs. 0.72 noma ngaphezulu) kanye nomthamo omncane (amalitha angu-500 vs. 750 amalitha noma ngaphezulu). Lona umphumela oqondile wosayizi wokuhlunga omncane. Sekukonke, sicabanga ukuthi lokhu kushiyeka okuncane kudlulwa ngosayizi wayo ohlangene. Uma wazi ukuthi udinga ukugeleza nokusebenza okuphezulu, i-Aquasana AQ-5300+ ilinganiselwe ku-0.72 GPM namalitha angu-800 kodwa ineshejuli efanayo yokushintsha isihlungi yezinyanga eziyisithupha, kuyilapho i-Aquasana Claryum Direct Connect inezinga lokugeleza elingafika kumalitha angu-1.5. ngomzuzu. , isilinganiso sokugeleza okujwayelekile singamalitha angu-1.5 ngomzuzu. kuze kufike kumalitha angama-784 nezinyanga eziyisithupha.
Imiyalo yokusebenza yohlelo lwe-AQ-5200 inomdwebo omncane futhi ezinye izingxenye aziboniswa ohlwini lwezingxenye noma imidwebo. Lokhu ngeke kubakhathaze abanikazi abaningi. Ngokuyisisekelo, okumele ukwenze nje ukuxhuma amapayipi ambalwa emanzini kanye nompompi, futhi yonke into izozichaza kancane. (Okuhlukile iwasha yokuhlobisa yensimbi engagqwali, engafakiwe ohlwini; ifakwa kuqala kumpompi, kulandele iwasha yerabha encane.) Uma sikhuluma iqiniso, kulokho esikubonile ocwaningweni lwethu. Kodwa siyethemba ukuthi iziqondiso zizobuyekezwa esikhathini esizayo. Okwamanje, nansi ividiyo evela kwa-Aquasana yokuthi ungayifaka kanjani i-AQ-5200.
Njengoba kushiwo ngenhla esigabeni esithi Sikhethe Kanjani, izihlungi zamanzi ezingaphansi kukasinki (kuhlanganise ne-AQ-5200) ngezinye izikhathi zihluleka ngendlela eyingozi, zidale umonakalo omkhulu wamanzi uma inkinga ingabonwa futhi ilungiswe ngokushesha. Qaphela ikakhulukazi lapho ufaka futhi ungazixhumi futhi uqinisekisa ukuthi ukuxhunywa kwepayipi kuvikelekile bese uvula amanzi kancane kancane ukuze uthole futhi ulungise ukuvuza ngaphambi kokuthi kube yinhlekelele. Ama-smart leak detectors angathola ukuvuza okuyinhlekelele, kungakhathaliseki ukuthi imbangela yawo, ngaphambi kokuba adale umonakalo omubi kakhulu.
Njengawo wonke amamodeli ethu, i-Aquasana AQ-5200 iza nompompi wayo ozimele, okungenzeka ungahambisani nesitayela sakho. Ungakwazi futhi ukufaka impompi ehlukene oyikhethayo inqobo nje uma usayizi woxhumano lwempompi iyiyintshi engu-⅜. Kodwa udinga ukuqhathanisa izinga lokugeleza kwayo ne-Aquasana engu-0.5 GPM ngoba ukuqinisekiswa kwesihlungi kusekelwe kuzinga lokugeleza. Sicela uqaphele ukuthi ngokobuchwepheshe, ukusebenzisa umpompi wakho kusho ukuthi isistimu yakho ayisaqinisekisiwe nge-ANSI/NSF.
Uma usola ukuthi amanzi akho aqukethe intlenga (i-tint ewolintshi ebangelwa ukugqwala iyinkomba; kanye nolwazi lwangaphambilini nganoma yiluphi uhlobo lwesihlungi, okuhlanganisa nezimbiza, ezivala ngaphambi kweminyaka yazo yokuphila okulindelekile), ungase ufune ukuhlola ezinye izihlungi ezifanayo. I-Aquasana AQ-5300 enesihlungi sangaphambili se-sediment.
Ithengiswa njenge (lungiselela ukulunywa) isihlungi samanzi esinezigaba ezimbili se-carbon block yamasistimu okuhlunga amanzi angaphansi kukasinki, i-AO Smith AO-US-200 iyasebenza nangokomzimba iyafana ne-top-of-the-line Aquasana AQ- 5200 ngazo zonke izindlela ezibalulekile. Inezitifiketi ezifanayo ze-ANS/NSF (PDF), usayizi ohlangene ofanayo, ubuchwepheshe bokuhlunga, ukwakhiwa kwensimbi yonke, ukufakwa kokucindezelwa, izinga lokugeleza elingu-0.5 GPM, kanye nomthamo wamagalani angama-500. Futhi ngokuvamile iza nesethi yezihlungi ezishintshayo cishe ngentengo efanayo. Akukho lutho olubi ngalokhu: U-AO Smith wathola i-Aquasana ngo-2016 futhi, umkhulumeli we-AO Smith wasitshela, “usebenzisa” ubuchwepheshe be-Aquasana futhi akanazo izinhlelo zokuqeda uphawu lwe-Aquasana.
