Intengiso ka-Okthobha ka-Amazon iyaqhubeka. Ukuze ufumane ezinye izibonelelo zeWirecutter ezifanele ukuthengwa, jonga uluhlu lwethu lwezona zibonelelo zibalaseleyo zePrime Day.
Nabani na osela amanzi angaphezu kweelitha ezimbalwa ngosuku uya kwaneliswa kakhulu yinkqubo yokucoca amanzi angaphantsi kwesinki efana ne-Aquasana AQ-5200. Ngokungafaniyo nejagi, isihluzo esingaphantsi kwesinki sibonelela ngamanzi rhoqo xa kufuneka. Sicebisa i-Aquasana AQ-5200 kuba iziqinisekiso zayo zezona zibalaseleyo kuyo nayiphi na inkqubo esiyifumeneyo; ziquka (njengezinye izisombululo zethu apha) i-chlorine, i-lead, i-mercury, i-PFAS, iintlobo ngeentlobo zee-pesticides, kunye ne-microplastics.
I-Aquasana AQ-5200 inesiqinisekiso se-ANSI/NSF kwaye inokususa phantse zonke iintlobo zezinto ezingcolisayo, kuquka i-lead, i-mercury, izibulali-zinambuzane, ii-microplastics, amayeza kunye nezinye izinto ezinokuthi zibanjwe ngabantu abambalwa abakhuphisana nabo. Yenye yezihluzo ezimbalwa eziqinisekisiweyo ukuba ziqulathe i-PFOA kunye ne-PFOS, iikhemikhali ezimbini ezihlala zihleli ezixhalabisa i-Arhente yoKhuseleko lweNdalo.
Ixabiso lokutshintsha iseti yezihluzo limalunga ne-$60, okanye i-$120 ngonyaka, ngokusekelwe kumjikelo wokutshintshwa ocetyiswayo yi-Aquasana weenyanga ezintandathu. Kwaye le nkqubo inkulu kancinci kuneetini ezimbalwa zesoda, ngoko ayithathi ndawo ingako ixabisekileyo phantsi kwesinki. Inezixhobo zesinyithi ezikumgangatho ophezulu kwaye iimpompo ziyafumaneka kwiindidi ezahlukeneyo zokugqiba.
I-AO Smith I-AO-US-200 ifana kakhulu ne-Aquasana AQ-5200 kuzo zonke iinkalo ezibalulekileyo. (Kungenxa yokuba i-AO Smith yafumana i-Aquasana ngo-2016.) Ineempawu ezifanayo zeprimiyamu, izixhobo zesinyithi zonke, kunye ne-compact form factor, kodwa ekubeni ithengiswa kuphela kwaLowe's, ayifumaneki kakhulu kwaye iifaucet zayo zinokugqitywa okukodwa kuphela. : i-nickel ebhrashiweyo. Iindleko zokutshintsha isihluzo ziyafana: malunga ne-$60 ngeseti nganye, okanye i-$120 ngonyaka kumjikelo weenyanga ezintandathu ocetyiswe yi-AO Smith.
Ineziqinisekiso ezifanayo nezibalaseleyo njenge-AQ-5200, kunye nokukwazi ukuhamba kwamanzi kunye nokucoca okuphezulu kune-AQ-5200, kunye nesihluzi sangaphambi kokususa iintsalela zomhlwa.
I-Aquasana AQ-5300+ Max Flow ineziqinisekiso ezifanayo nezibalaseleyo njengokhetho lwethu oluphezulu, kodwa inika ukuhamba okuphezulu (0.72 gpm vs. 0.5 gpm) kunye nomthamo wokucoca (800 gpm vs. 500). Oku kwenza ukuba ibe lukhetho olufanelekileyo kumakhaya afuna amanzi amaninzi ahluziweyo kwaye afuna ngokukhawuleza. Ikwadibanisa isihluzo sangaphambi kwesediment esingenayo i-AQ-5200; oku kunokwandisa isihluzo esingcolisayo ngamanani aphezulu okuhamba kwamanzi kumakhaya anamanzi atyebileyo kwisediment. Nangona kunjalo, i-AQ-5300+ (enezihluzo ezinobukhulu bebhotile yeelitha ezintathu) inkulu kakhulu kune-AQ-5200, kwaye iindleko zokuqala kunye nokutshintsha isihluzo ziphezulu kancinci (malunga ne-$80 ngeseti nganye okanye i-$160 ngonyaka).
Ifakelwa ngaphandle kokubhoboza kwaye ihambisa ukuya kuthi ga kwi-1.5 yeegaloni zamanzi ngomzuzu ngokusebenzisa iimpompo ezikhoyo.
I-Claryum Direct Connect ka-Aquasana iqhagamshela ngqo kwiimpompo ezikhoyo, nto leyo eyenza ukuba ibe lukhetho olunomtsalane kakhulu kubantu abaqeshileyo (abanokuthintelwa kukuhamba) kunye nabo bangakwaziyo ukufaka i-filter faucet eyahlukileyo. Akunyanzelekanga nokuba ifakwe eludongeni lwekhabhinethi phantsi kwesinki, imile nje ecaleni kwayo. Ineziqinisekiso ze-ANSI/NSF ezifanayo nezinye iimodeli ze-Aquasana kunye ne-AO Smith kwaye inokuhambisa ukuya kuthi ga kwi-1.5 yeegaloni zamanzi ahluziweyo ngomzuzu. Esi sihluzo sinomthamo olinganiselweyo weegaloni ezingama-784 kwaye kufuneka sihlale malunga neenyanga ezintandathu. Kodwa asinayo i-sediment pre-filter. Ke ngoko, ukuba uneengxaki nge-sediment, le ayilona khetho lilungileyo kuba inokuxinana lula. Kwaye inkulu—20.5 x 4.5 intshi—ngoko ke ukuba ikhabhinethi yakho yesinki incinci okanye ixinene kakhulu, isenokungangeni.
Ineziqinisekiso ezifanayo nezibalaseleyo njenge-AQ-5200, kunye nokukwazi ukuhamba kwamanzi kunye nokucoca okuphezulu kune-AQ-5200, kunye nesihluzi sangaphambi kokususa iintsalela zomhlwa.
Ifakelwa ngaphandle kokubhoboza kwaye ihambisa ukuya kuthi ga kwi-1.5 yeegaloni zamanzi ngomzuzu ngokusebenzisa iimpompo ezikhoyo.
Ndibe ndivavanya izihluzo zamanzi zeWirecutter ukusukela ngo-2016. Kwingxelo yam, ndithethe ngokweenkcukacha nemibutho eqinisekisa izihluzo ukuze ndiqonde indlela oluqhutywa ngayo uvavanyo lwabo, kwaye ndangena kwiidathabheyisi zabo zikawonke-wonke ukuqinisekisa ukuba amabango abavelisi axhaswa yi: Uvavanyo oluqinisekisiweyo. Ndithethe nabameli babavelisi abaninzi bezihluzo zamanzi, kuquka i-Aquasana/AO Smith, i-Filtrete, i-Brita kunye ne-Pur, ukuze ndiphikise amabango abo. Mna ngokwam ndizame zonke iindlela zethu kuba ukuthembeka ngokubanzi, ukuqina, kunye nokusetyenziswa kubaluleke kakhulu kwisixhobo esisetyenziswa izihlandlo ezininzi ngemini.
Owayesakuba yingcali yesayensi ye-NOAA uJohn Holecek uphande waza wabhala incwadi yokuqala yesihluzo samanzi seWirecutter, wenza uvavanyo lwakhe, wayalela ukuba kwenziwe olunye uvavanyo oluzimeleyo, waza wandifundisa okuninzi koko ndikwaziyo. Umsebenzi wam usekelwe kumsebenzi wakhe.
Ngelishwa, akukho mpendulo iqhelekileyo kumbuzo wokuba ingaba uyayidinga na i-water filter okanye akunjalo. E-United States, unikezelo lwamanzi kawonke-wonke lulawulwa yi-US Environmental Protection Agency phantsi koMthetho waManzi acocekileyo, kwaye amanzi aphuma kwizityalo zonyango lwamanzi kawonke-wonke kufuneka ahlangabezane nemigangatho engqongqo yomgangatho. Kodwa ayizizo zonke izinto ezingcolisayo ezilawulwayo. Ukongeza, izinto ezingcolisayo zinokungena emanzini emva kokuba ephumile kwisityalo sonyango, nokuba ngemibhobho evuzayo (PDF) okanye ngokuphuma kwimibhobho ngokwazo. Unyango lwamanzi olwenziwe (okanye olungahoywayo) kwisityalo lunokubhebhethekisa ukuvuza kwimibhobho esezantsi, njengoko kwenzekile eFlint, eMichigan.
Ukuze ufumane kanye kanye ukuba yintoni na emanzini omthengisi wakho, unokukhangela kwi-intanethi ingxelo yokuzithemba kwabathengi evunyiweyo yi-EPA yomthengisi wakho wasekuhlaleni; kungenjalo, bonke ababoneleli bamanzi kawonke-wonke kufuneka bakunike ii-CCR zabo xa becela. Kodwa ngenxa yongcoliseko olunokubakho oluya kulandela, indlela ekuphela kwayo yokufumanisa ukuba yintoni na emanzini ekhayeni lakho kukuhlawula ilebhu yomgangatho wamanzi yasekuhlaleni ukuze iwavavanye.
Njengomgaqo jikelele, okukhona ikhaya lakho okanye indawo ohlala kuyo indala, kokukhona umngcipheko wokungcola okungaphantsi komsinga uphezulu. I-Environmental Protection Agency ibika ukuba “amakhaya akhiwe ngaphambi kowama-1986 anokuba nemibhobho yelothe, izixhobo kunye ne-solder”—izinto ezindala, ezazikade ziqhelekile ezingahlangabezaniyo neekhowudi zangoku. Ukuguga kwandisa amathuba okungcoliswa kwamanzi angaphantsi komhlaba agugayo ngamashishini alawulwa ngaphambili, nto leyo enokuba yingozi, ingakumbi xa idibene nokuwohloka kwemibhobho engaphantsi komhlaba okunxulumene nobudala.
Ukuba usapho lwakho lusebenzisa amanzi okusela angaphezu kweelitha ezimbini ukuya kwezintathu ngosuku, isihluzo samanzi esingaphantsi kwesinki sinokuba lukhetho olungcono kunesihluzo sepitcher. Iinkqubo ezingaphantsi kwesinki zibonelela ngamanzi okusela ahluziweyo xa kufuneka, zisusa isidingo sokulinda inkqubo yokucoca igqitywe njengakwipitcher. Ukucoca xa kufuneka kukwathetha ukuba inkqubo engaphantsi kwesinki inokubonelela ngamanzi aneleyo okupheka—umzekelo, ungazalisa imbiza ngamanzi ahluziweyo ukupheka ipasta, kodwa akusayi kufuneka uyizalise kwakhona ipitcher ngaloo njongo.
Xa kuthelekiswa nezihluzo zepitcher, izihluzo ezingaphantsi kwesinki zidla ngokuba namandla amakhulu kwaye zihlala ixesha elide—ngesiqhelo zifikelela kumakhulu aliqela eegaloni kunye neenyanga ezintandathu nangaphezulu xa kuthelekiswa nobukhulu beegaloni ezingama-40 zeefilitha ezininzi zepitcher kunye neenyanga ezimbini. Ngenxa yokuba izihluzo ezingaphantsi kwesinki zisebenzisa uxinzelelo lwamanzi endaweni yomxhuzulane ukutyhala amanzi kwisihluzo, izihluzo zazo zinokuba nzima kwaye ngaloo ndlela zisuse uluhlu olubanzi lwezinto ezingcolisayo.
Ingxaki kukuba zibiza kakhulu ngaphambili kunezihluzi zepitcher, kwaye izihluzi ezitshintshayo nazo zibiza kakhulu ngokwexabiso elipheleleyo nangomndilili ngokuhamba kwexesha. Le nkqubo ikwathatha indawo yeekhabhathi phantsi kwesinki ebinokusetyenziselwa ukugcina izinto.
Ukufaka isihluzo esingaphantsi kwesinki kufuna ukufakwa kwezixhobo zombhobho kunye nepayipi, kodwa umsebenzi ulula kuphela ukuba isinki yakho sele inomngxuma wempompo eyahlukileyo. Ngaphandle koko, kuya kufuneka ususe enye yeendawo zempompo eyakhelwe ngaphakathi (idiski ephakanyisiweyo kwisinki yentsimbi okanye uphawu kwisinki yelitye elenziweyo). Ukuba awunamngxuma wokugqobhoza, kuya kufuneka ugqobhoze umngxuma kwisinki okanye kwikhawuntara ukuba isinki yakho ayifakwanga kakuhle. Ukuba unesixhobo sokukhupha isepha okanye isitshizi sesandla kwisinki yakho, ungayisusa kwaye ufake impompo. (Musa ukufaka impompo apho kukho umngxuma womoya - oku kwenzelwa ukuthintela amanzi angcolileyo okuhlamba ukuba angangeni kwisitya sokuhlamba izitya.)
Phantse isiqingatha samanzi empompini aqulethe iikhemikhali ezingapheliyo. Nantsi indlela yokufumanisa ukuba usemngciphekweni kwaye unciphise ukuvezwa kwakho.
Esi sikhokelo simalunga nohlobo oluthile lwesihluzo esingaphantsi kwesinki: ezo zisebenzisa isihluzo sekhatriji. Zithatha indawo encinci kakhulu kwaye kulula kakhulu ukuzifaka nokuzigcina. Zisebenzisa izinto ezifaka i-adsorbent (ngokuqhelekileyo ii-activated carbon kunye ne-ion exchange resins ezifana nezihluzo zepitcher) ukubopha nokuphelisa ukungcola. Uninzi lufakelwa kwi-faucet eyahlukileyo (ifakiwe), oko kuthetha ukuba uya kufuna umngxuma wokufaka kwi-countertop; Umngxuma owenzelwe ipayipi yokutshiza uya kusebenza, okanye ungagqobhoza umngxuma omtsha. Asithethi ngezihluzo zokufaka i-faucet, iinkqubo ze-reverse osmosis, okanye ezinye ii-water pitchers okanye ii-dispensers.
Ukuqinisekisa ukuba sicebisa kuphela izihluzo onokuzithemba, sihlala sigxininisa ukuba ukhetho lwethu luqinisekiswe ngokwemigangatho yoshishino: i-ANSI/NSF. I-American National Standards Institute kunye ne-NSF International yimibutho yabucala, engenzi nzuzo esebenza ne-Environmental Protection Agency, ishishini kunye nezinye iingcali ukuphuhlisa imigangatho yomgangatho engqongqo kunye neenkqubo zokuvavanya amawaka eemveliso, kuquka izihluzo zamanzi. Iilabhoratri ezimbini eziphambili zokuqinisekiswa kwezihluzo zamanzi yi-NSF International ngokwayo kunye ne-Water Quality Association (WQA). Zombini iimveliso zivunyiwe ngokupheleleyo yi-ANSI kunye neKhansile yeMigangatho yaseKhanada eMntla Melika ukuze kuvavanywe isiqinisekiso se-ANSI/NSF, kwaye zombini kufuneka zilandele imigangatho efanayo kunye neenkqubo zokuvavanya. Kuphela emva kokusebenzisa iisampulu "zovavanyo" ezilungisiweyo, ezazingcoliseke kakhulu kunamanzi amaninzi epompo, apho isihluzo sahlala ixesha elide ngaphaya kobomi obulindelweyo kwaye sahlangabezana nemigangatho yokuqinisekiswa.
Kule khokelo, siza kugxila kwiifilitha eziqinisekisiweyo ukuba zine-chlorine, i-lead, kunye nee-volatile organic compounds (ii-VOC).
Isiqinisekiso se-chlorine sibalulekile kuba i-chlorine yeyona nto ixhaphakileyo kwivumba "elibi" emanzini empompi. Kodwa oku kuphantse kube yintsikelelo: phantse zonke iintlobo zezihluzi zamanzi ziqinisekisiwe.
Ukufumana isiqinisekiso se-lead kunzima kuba kuthetha ukunciphisa izisombululo ezityebileyo nge-lead ngaphezulu kwama-99%.
Isatifikethi se-VOC sikwanzima kuba sithetha ukuba isihluzo sinokususa iikhompawundi zendalo ezingaphezu kwama-50, kuquka ii-biocides ezininzi eziqhelekileyo kunye nezinto ezisetyenziswa kwimizi-mveliso. Ayizizo zonke izihluzi ezingaphantsi kwesinki ezineziqinisekiso zombini, ngoko ke ngokugxila kwizihluzi ezineziqinisekiso zombini, sichonge izihluzi ezisebenza ngcono kakhulu.
Sinciphise uphando lwethu ngakumbi saza sakhetha izihluzi ngeziqinisekiso ezongezelelweyo ukuya kumgangatho omtsha we-ANSI/NSF 401, ogubungela izinto ezingcolisayo ezifumaneka emanzini e-United States, ezifana namayeza. Ngokufanayo, ayizizo zonke izihluzi ezineziqinisekiso ze-401. Ke ngoko, ezo zibonelelo zineziqinisekiso ze-401 (kunye ne-lead kunye ne-VOC) zikwiqela elikhethwe ngononophelo.
Emva koko, ngaphakathi kwesi sixhobo siqinileyo, sikhangela iimveliso ezinomthamo omncinci weegaloni ezingama-500. Oku kulingana neenyanga ezintandathu zobomi bokucoca phantsi kokusetyenziswa kakhulu (iigaloni ezingama-2.75 ngosuku). La manzi ahluziweyo anele uninzi lweentsapho ukusela nokupheka imihla ngemihla. (Abavelisi banikezela ngeeshedyuli ezicetyiswayo zokutshintsha izihluzi, ngesiqhelo kwiinyanga kuneegaloni; silandela ezi ngcebiso kuqikelelo lwethu kunye nokubala iindleko. Sicebisa ukuba sisebenzise iindawo zokutshintsha zomenzi wokuqala endaweni yezihluzi zomntu wesithathu.)
Ekugqibeleni, silinganise iindleko zokuqala zenkqubo yonke ngokuthelekisa neendleko eziqhubekayo zokutshintsha izihluzi. Asikabeki xabiso okanye isilingi, kodwa uphando lwethu lubonise ukuba nangona iindleko zokuqala zaziqala kwi-$100 ukuya kwi-$1,250 kwaye iindleko zezihluzi zaziqala kwi-$60 ukuya phantse kwi-$300, la mahluko awazange aguqulele ekusebenzeni okuphezulu kakhulu. Iimodeli ezibiza kakhulu. Sifumene izihluzi ezininzi ezingaphantsi kwesinki ezixabisa ngaphantsi kwe-$200 kodwa ziseneziqinisekiso ezigqwesileyo kunye nokuqina. Aba ngabantu ababa ngabaphumeleleyo kuthi. Phakathi kwezinye izinto esizifunayo:
Ngexesha lophando lwethu, ngamanye amaxesha besifumana iingxelo zokuvuza okubi kakhulu kubanini bezihluzo zamanzi ezingaphantsi kwesinki. Ngenxa yokuba isihluzo siqhagamshelwe kumthombo wamanzi abandayo, ukuba isixhumi okanye ipayipi iyaphuka, amanzi anokuvuza de ivalvu ivalwe, ngoko ke kungathatha iiyure okanye iintsuku ukufumanisa ingxaki, nto leyo enokubangela iziphumo ezibi kuwe. Umonakalo wamanzi. Akuvamile, kodwa xa ucinga ngokuthenga isihluzo esingaphantsi kwesinki, kufuneka ulinganisele iingozi. Ukuba uthenge esinye, landela imiyalelo yokufakela ngononophelo, uqaphele ukuba ungajiki izixhumi ngendlela engafanelekanga, uze ubuye uvule amanzi kancinci ukuze ujonge ukuvuza. Ukuze ufumane uxolo lwengqondo olongezelelekileyo (ukusombulula zonke iingxaki zakho zombhobho, kungekuphela nje isihluzo esingaphantsi kwesinki), cinga ngokufaka isixhobo sokubona ukuvuza esikrelekrele.
Izihluzi ze-reverse osmosis (R/O) ekuqaleni zinohlobo olufanayo lwesihluzi sekhatriji njengeso sikhethileyo apha, kodwa yongeza indlela yesibini yokucoca i-reverse osmosis: i-membrane enemingxuma emincinci evumela amanzi ukuba adlule kodwa ihluze iiminerali ezinyibilikisiweyo kunye nezinye izinto.
Singaxoxa ngeefilitha ze-R/O ngokweenkcukacha kwisifundo sexesha elizayo. Apha siyazalela ngokupheleleyo. Zineengenelo ezilinganiselweyo zokusebenza kunezifilitha zokufunxa; zivelisa amanzi amaninzi amdaka (ngesiqhelo iilitha ezi-4 zamanzi "okuhlamba" inkunkuma ngegaloni nganye ehluziweyo), ngelixa izifilitha zokufunxa zingavelisi manzi amdaka; Zithatha indawo engakumbi kuba, ngokungafaniyo nezifilitha zokufunxa, zisebenzisa itanki eli-1 okanye eli-2 legaloni ukugcina amanzi ahluziweyo; kwaye zisebenza kancinci kakhulu kunezifilitha zokufunxa ezingaphantsi kwesinki.
Besivavanya izihluzi zamanzi kwilabhoratri kwiminyaka eliqela edlulileyo, kwaye into ephambili esiyifundayo kuvavanyo lwethu kukuba isiqinisekiso se-ANSI/NSF sisalathisi esithembekileyo sokusebenza kwesihluzi. Oku akumangalisi xa ucinga ngobunzima obukhulu bovavanyo lwesiqinisekiso. Ukususela ngoko, sithembele kwisiqinisekiso se-ANSI/NSF ukukhetha abakhuphisana nabo endaweni yovavanyo lwethu olulinganiselweyo.
Ngowama-2018, savavanya inkqubo yokucoca amanzi edumileyo iBig Berkey, engaqinisekiswanga yi-ANSI/NSF kodwa ithi ivavanywe kakhulu ukuhlangabezana nemigangatho ye-ANSI/NSF. Olu lwazi lomeleze ngakumbi ukuzibophelela kwethu kwisiqinisekiso sokwenyani se-ANSI/NSF kunye nokungathembi kwethu amabango athi “ANSI/NSF Verified”.
Ukususela ngoko, kuquka nango-2019, uvavanyo lwethu luye lwagxila ekusebenziseni izinto zokwenyani kunye neempawu ezisebenzayo kunye neentsilelo ezibonakala ngokucacileyo njengoko usebenzisa iimveliso.
Sikhethe i-Aquasana AQ-5200, ekwaziwa ngokuba yi-Aquasana Claryum Dual-Stage. Eyona nto ibalulekileyo kukuba izihluzo zayo zineziqinisekiso ze-ANSI/NSF ezilungileyo phakathi kwabakhuphisana nathi ze-chlorine, ii-chloramines, i-lead, i-mercury, ii-VOC, "izinto ezininzi ezingcolisayo ezivelayo," ii-microplastics, kunye ne-PFOA kunye ne-PFOS. Ukongeza, iifaucet kunye nezinto ezisetyenziswayo zenziwe ngesinyithi esiqinileyo, esingcono kuneplastiki esetyenziswa ngabanye abavelisi. Ukongeza, inkqubo incinci kakhulu. Ekugqibeleni, i-Aquasana AQ-5200 yenye yezona ndlela zibalaseleyo esizifumeneyo kwizihluzo ezingaphantsi kwesinki, kunye nenkqubo yonke (isihluzo, indlu, i-faucet, kunye nehardware) idla ngokubiza malunga ne-$140 ngaphambili okanye iseti yezihluzo ezimbini ezithatha indawo ye-$60. Oku kuncinci kunabaninzi abakhuphisana nabo abaneziqinisekiso ezibuthathaka.
Isiqinisekiso se-ANSI/NSF (PDF) se-AQ-5200 Iqulethe i-chlorine, esetyenziselwa ukubulala iintsholongwane kwiindawo zamanzi zikamasipala kwaye yeyona nto iphambili ebangela "ivumba elibi" emanzini epompo; i-lead, enokuphuma kwimibhobho emidala kunye ne-pipe solder. ; i-mercury; i-Viable Cryptosporidium kunye ne-Giardia, iintsholongwane ezimbini ezinokubakho; i-Chloramine sisibulali-ntsholongwane se-chlorine-ammonia esihlala sisetyenziswa kwizityalo zokucoca kumazantsi e-United States. I-chlorine ecocekileyo ibola ngokukhawuleza emanzini afudumeleyo. I-AQ-5200 ikwaqinisekisiwe ngokuchasene "nezinto ezingcolisayo ezivelayo" ezili-15 ezibonakala ngakumbi kwiindawo zamanzi, kubandakanya i-BPA, i-ibuprofen kunye ne-estrone (i-estrogen esetyenziswa kulawulo lokuzalwa), ii-microplastics, kunye ne-PFOA kunye ne-PFOS, iikhompawundi ezisekwe kwi-fluoride yemizi-mveliso. zifumaneka kakhulu emanzini epompo ase-US. Ikwaqinisekisiwe yi-VOC. Oku kuthetha ukuba inokususa ngempumelelo iikhompawundi ezahlukeneyo ze-organic ezingaphezu kwama-50, kubandakanya izibulali-zinambuzane ezininzi kunye nezinto ezisandula ukwenziwa kwimizi-mveliso.
Ukongeza kwi-activated carbon kunye ne-ion exchange resin (ezisetyenziswa kwizihluzi ezininzi, ukuba azikho zonke, ezingaphantsi kwesinki), i-Aquasana isebenzisa ubuchwepheshe obubini bokucoca ukuze ifumane isiqinisekiso. Kwi-chloramines, kongezwa i-catalytic carbon, oko kukuthi, i-activated carbon, enemingxuma kwaye ngenxa yoko isabela ngakumbi, eyenziwe ngokunyanga i-carbon ngegesi enobushushu obuphezulu. Kwi-cryptosporidium kunye ne-giardia, i-Aquasana ivelisa izihluzi ezinobukhulu beemingxuma ezincitshiswe ukuya kwi-0.5 microns, ezincinci ngokwaneleyo ukuba zibambe ngokwasemzimbeni.
Isiqinisekiso se-Aquasana AQ-5200 filter yayiyeyona nto iphambili esiyikhethileyo. Kodwa uyilo kunye nezixhobo zayo nazo ziyayihlukanisa nezinye. I-faucet yenziwe ngentsimbi eqinileyo, kunye ne-T-piece edibanisa i-filter kumbhobho. Abanye abakhuphisana nabo basebenzisa iplastiki kwenye okanye zombini, nto leyo enciphisa iindleko kodwa yandisa umngcipheko wokuwela amaqhosha kunye nokufakwa okungafanelekanga. I-AQ-5200 isebenzisa izixhobo zokucinezela ukwenza uphawu oluqinileyo nolukhuselekileyo phakathi kombhobho kunye netyhubhu yeplastiki ethwala amanzi ukuya kwisihluzo nakwi-faucet. Abanye abakhuphisana nabo basebenzisa izixhobo ezilula, ezingathembekanga kangako. I-AQ-5200 faucet ifumaneka ngeendlela ezintathu (i-nickel ebhrashiweyo, i-chrome epholisiweyo kunye ne-bronze ebhrashiweyo ngeoyile), ngelixa abanye abakhuphisana nabo bengakushiyi nanye indlela.
Sikwathanda ne-compact form factor yenkqubo ye-AQ-5200. Isebenzisa izihluzi ezimbini, ngasinye sikhulu kancinci kune-soda can; ezinye izihluzi, kuquka i-Aquasana AQ-5300+ ngezantsi, zenzelwe iibhotile zelitha. Xa isihluzi sifakwe kwi-bracket yokufakela, i-AQ-5200 inobude obuziisentimitha ezili-9, ububanzi obuziisentimitha ezili-8, kunye nobunzulu obuziisentimitha ezili-4; I-Aquasana AQ-5300+ inobude obuziisentimitha ezili-13 x 12 x 4. Oku kuthetha ukuba i-AQ-5200 ithatha indawo encinci kakhulu yekhabhinethi engaphantsi kwesinki, ivumela ukuba ifakwe kwiindawo ezixineneyo apho iinkqubo ezinkulu zingenakufakelwa khona, ishiya indawo yokugcina engaphezulu kwesinki. Uya kufuna indawo ethe nkqo emalunga ne-intshi ezili-11 (elinganiswe ukusuka phezulu kwekhabhinethi ukuya ezantsi) ukuze utshintshe isihluzi kunye nendawo ethe tyaba emalunga ne-intshi ezili-9 ecaleni kweendonga zekhabhinethi ukuze ufake ikhabhinethi.
I-AQ-5200 ifumene uphononongo oluhle kakhulu njengesihluzo samanzi, ifumene iinkwenkwezi ezi-4.5 kwi-5 kwi-800 ngaphezulu kwe-800 kwiwebhusayithi ye-Aquasana kunye neenkwenkwezi ezi-4.5 kwi-500 phantse kwi-500 kwi-Home Depot.
Okokugqibela, ngexabiso langoku elimalunga ne-$140 kuyo yonke inkqubo (ngesiqhelo ixabiso limalunga ne-$100) kunye ne-$60 kwiseti yezihluzo zokutshintsha ($120 ngonyaka kunye nomjikelo wokutshintsha weenyanga ezintandathu), i-Aquasana AQ-5200 yinto esiyifunayo. Enye yezona zivumelwano zibalaseleyo phakathi kwabakhuphisanayo kwaye ixabisa amakhulu eedola kunezinye iimodeli ezineziqinisekiso ezincinci. Esi sixhobo sinexesha elikhalayo xa ufuna ukutshintsha isihluzo, kodwa sicebisa ukuba usete nezikhumbuzi zekhalenda rhoqo kwifowuni yakho. (Akunakwenzeka ukuba uphoswe koku.)
Xa kuthelekiswa nabanye abakhuphisana nabo, i-Aquasana AQ-5200 inesantya sokuhamba esiphezulu esiphantsi (0.5 gpm vs. 0.72 okanye ngaphezulu) kunye nomthamo omncinci (500 gallons vs. 750 gallons okanye ngaphezulu). Oku kubangelwa ngqo bubungakanani besihluzo esincinci ngokomzimba. Ngokubanzi, sicinga ukuba ezi ntsilelo zincinci zingaphezulu kobukhulu bayo obuncinci. Ukuba uyazi ukuba ufuna ukuhamba okuphezulu nokusebenza, i-Aquasana AQ-5300+ ilinganiswe kwi-0.72 GPM kunye neegaloni ezingama-800 kodwa ineshedyuli efanayo yokutshintsha isihluzo seenyanga ezintandathu, ngelixa i-Aquasana Claryum Direct Connect inesantya sokuhamba esifikelela kwi-1.5 gallons ngomzuzu. , isantya sokuhamba esiqhelekileyo yi-1.5 gallons ngomzuzu. ukuya kuthi ga kwi-784 gallons kunye neenyanga ezintandathu.
Imiyalelo yokusebenza kwenkqubo ye-AQ-5200 ayicacanga kangako kwaye ezinye iindawo aziboniswanga kuluhlu lwamacandelo okanye kwimizobo. Oku akuyi kubakhathaza uninzi lwabanini. Ngokusisiseko, okufuneka ukwenze kukudibanisa imibhobho embalwa kumthombo wamanzi kunye neempompo, kwaye yonke into iya kuzichaza. (Okwahlukileyo yi-washer yokuhombisa yentsimbi engagqwaliyo, engadweliswanga; ifakwe kuqala kwimpompo, ilandelwe yi-washer yerabha ebhityileyo.) Ngokwenyani, kwinto esiyibonileyo kuphando lwethu. Kodwa sinethemba lokuba izikhokelo ziya kuhlaziywa kwixesha elizayo. Okwangoku, nantsi ividiyo evela ku-Aquasana malunga nendlela yokufaka i-AQ-5200.
Njengoko kukhankanyiwe apha ngasentla kwicandelo leHow We Choose, izihluzi zamanzi ezingaphantsi kwesinki (kuquka i-AQ-5200) ngamanye amaxesha ziyasilela ngendlela engalindelekanga, nto leyo ebangela umonakalo omkhulu wamanzi ukuba ingxaki ayifunyaniswanga kwaye ayilungiswanga ngokukhawuleza. Lumka ngakumbi xa ufaka kwaye ungafaki izihlanganisi ezidibanisayo kwaye uqinisekisa ukuba uqhagamshelo lwepayipi lukhuselekile uze ubuyisele amanzi kancinci kancinci ukuze ukwazi ukufumana nokulungisa ukuvuza ngaphambi kokuba kube yintlekele. Izibonisi zokuvuza ezikrelekrele zinokubona ukuvuza okubi, nokuba yintoni na imbangela yako, ngaphambi kokuba zenze umonakalo omkhulu.
Njengazo zonke iimodeli zethu, i-Aquasana AQ-5200 iza ne-faucet yayo ezimeleyo, esenokungahambelani nesitayile sakho. Ungayifaka ne-faucet eyahlukileyo oyikhethileyo logama nje ubungakanani boqhagamshelo lwe-faucet buyi-intshi ezi-⅜. Kodwa kufuneka uthelekise izinga lokuhamba kwayo ne-Aquasana's 0.5 GPM kuba isiqinisekiso sesihluzi sisekelwe kwinqanaba lokuhamba. Nceda uqaphele ukuba ngokwetekhnoloji, ukusebenzisa i-faucet yakho kuthetha ukuba inkqubo yakho ayisaqinisekiswa yi-ANSI/NSF.
Ukuba ukrokrela ukuba amanzi akho ane-sediment (umbala o-orenji obangelwa ngumhlwa uyindlela yokubonisa; kunye namava angaphambili ngalo naluphi na uhlobo lwesihluzo, kuquka neepitcher, ezivalekileyo ngaphambi kokuba zihlale ixesha elide), ungafuna ukujonga ezinye izihluzo ezifanayo. I-Aquasana AQ-5300 ene-sediment pre-filter eyongezelelweyo.
Ithengiswa njengesihluzo samanzi acocekileyo esineebhloko ezimbini zekhabhoni (esilungele ukulunywa) kwiinkqubo zokucoca amanzi ezingaphantsi kwesinki, i-AO Smith AO-US-200 ifana kakhulu ne-Aquasana AQ-5200 ephezulu kuzo zonke iindlela ezibalulekileyo. Ineziqinisekiso ezifanayo ze-ANS/NSF (PDF), ubungakanani obufanayo, iteknoloji yokucoca, ulwakhiwo lwesinyithi esipheleleyo, izixhobo zoxinzelelo, izinga lokuhamba kwe-0.5 GPM, kunye nomthamo weegaloni ezingama-500. Ikwahlala iza neseti yezihluzo zokutshintsha ngexabiso elifanayo. Akukho nto imbi ngale nto: I-AO Smith yafumana i-Aquasana ngo-2016 kwaye, isithethi se-AO Smith sisixelele ukuba, "isebenzisa" ubuchule be-Aquasana kwaye ayinazicwangciso zokuphelisa uphawu lwe-Aquasana.
