Senze kwakhona i-Aquasana Claryum Direct Connect ikhetheke kakuhle-kulula ukuyifaka kwaye inokubonelela ngokuhamba kwamanzi aphezulu kwiifaucets ezikhoyo.
Nabani na osela ngaphezu kweelitha ezimbalwa zamanzi okusela ngosuku unokuthanda ukusebenzisa inkqubo yokucoca ngaphantsi kwetanki njenge-Aquasana AQ-5200. Ukuba ukhetha (okanye ufuna) amanzi ahluziweyo, oku kunokubonelelwa ngokuqhubekayo ukusuka kwitephu eyahlukileyo njengoko kufuneka. Sincoma i-Aquasana AQ-5200 kuba isiqinisekiso sayo sisona silungileyo kuzo zonke iinkqubo esizifumeneyo.
I-Aquasana AQ-5200 ifumene isiqinisekiso esingcolisekileyo, sifumaneka ngokubanzi, sinexabiso elifanelekileyo, kwaye sinesakhiwo esincinci. Yinkqubo yokuqala yokuhluza amanzi angaphantsi kwetanki esiyifunayo.
I-Aquasana AQ-5200 iphumelele isiqinisekiso se-ANSI / NSF kwaye inokuphelisa phantse i-77 engcolileyo ehlukeneyo, kuquka i-load, i-mercury, i-volatile organic compounds, iziyobisi, kunye nezinye izinto ezingafane zibanjwe ngabakhuphisana nabo. Sesinye sezihluzo ezimbalwa kakhulu eziqinisekisiweyo zePFOA kunye nePFOS. Ezi khompawundi zibandakanyeka ekwenziweni kwezinto ezingabambekiyo kwaye zafumana ingcebiso yezempilo ye-EPA ngoFebruwari ka-2019.
Iindleko zokutshintsha iseti yezihluzi zimalunga ne-US$60, okanye ixesha leenyanga ezintandathu elicetyiswa ngu-Aquasana li-US$120 ngonyaka. Ngaphezu koko, inkqubo inkulu kuphela kuneetoti ezimbalwa zesoda kwaye ayithathi indawo eninzi exabisekileyo phantsi kwe-sink. Le nkqubo isetyenziswa ngokubanzi isebenzisa izixhobo zentsimbi ezikumgangatho ophezulu, kwaye iimpompo zayo ziza kwiintlobo ezahlukeneyo zokugqitywa.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 ngokubhekiselele kwisatifikethi, iinkcukacha kunye nemilinganiselo. Yahlukile kwekaLowe kwaye ke ayifumaneki kakhulu.
I-AO Smith i-AO-US-200 iyafana ne-Aquasana AQ-5200 kuzo zonke iinkalo ezibalulekileyo. (Oku kungenxa yokuba i-AO Smith ifumene i-Aquasana kwi-2016.) Inesiqinisekiso esifanayo esihle kakhulu, i-hardware yensimbi yonke, kunye ne-compact form factor, kodwa ngenxa yokuba ithengiswa kuphela kwi-Lowe, uluhlu lwayo lokuthengisa alubanzi, kunye ne-faucet yayo Kukho. isiphelo esinye kuphela: nickel ebrashiweyo. Ukuba oku kuhambelana nesitayile sakho, sincoma ukuthenga phakathi kweemodeli ezimbini ngexabiso: enye okanye enye ihlala ithotywa. Iindleko zokutshintshwa kwesihluzi ziyafana: malunga ne-$ 60 yesethi, okanye i-$ 120 ngonyaka kwisithuba seenyanga ezintandathu esicetyiswa ngu-AO Smith.
I-AQ-5300 + inesatifikethi esifanayo esihle kakhulu, kodwa ngesantya esiphezulu sokuhamba kunye nomthamo wokuhluza, ifanelekile kumakhaya asebenzisa amanzi amaninzi, kodwa ixabiso liphezulu kwaye lithatha indawo engaphezulu phantsi kwe-sink.
I-Aquasana AQ-5300 + ukuhamba okuphezulu kune-77 ANSI / NSF iziqinisekiso njengezinye iimveliso ezikhethiweyo, kodwa inikezela ukuhamba okuphezulu (i-0.72 kunye ne-0.5 yeegaloni ngomzuzu) kunye nomthamo wokucoca (800 kunye ne-500 yeegaloni). Oku kwenza kube lukhetho lokuqala kwiintsapho ezifuna amanzi amaninzi ahluziweyo kwaye zifuna ukuwasebenzisa ngokukhawuleza. Kwakhona yongeza i-sediment pre-filter, engafumanekiyo kwi-AQ-5200; oku kunokwandisa izinga lokuqukuqela okuphezulu kwesihluzo esingcolisayo kumakhaya atyebileyo ngamanzi entlenga. Ngamanye amazwi, imodeli ye-AQ-5300 + (exhotywe nge-3-litre filter filter) inkulu kakhulu kune-AQ-5200 kunye ne-AO Smith AO-US-200, kodwa ubomi bokucoca obucetyiswayo bufana, iinyanga ezintandathu. Kwaye iindleko zayo zangaphambili kunye neendleko zokutshintsha isihluzo ziphezulu (malunga ne-80 yeedola zase-US kwiseti okanye i-160 yeedola zase-US ngonyaka). Ngoko ke, linganisela izibonelelo zayo kunye neendleko eziphezulu.
I-Claryum Direct Connect ingafakelwa ngaphandle kokugrunjwa kwaye ihambise ukuya kuthi ga kwi-1.5 yeelitha zamanzi ahluziweyo ngomzuzu ngempompo yakho ekhoyo.
I-Aquasana's Claryum Direct Connect iqhagamshela ngokuthe ngqo kwitephu yakho ekhoyo, iyenza ibe yeyona ndlela inomtsalane ngakumbi kubaqeshi (basenokuthintelwa ekutshintsheni indawo abakuyo) kunye nabo bangakwaziyo ukufaka itephu yokucoca eyahlukileyo. Akunyanzelekanga nokuba ifakwe eludongeni lwekhabhathi yesinki-inokubekwa nje ecaleni kwayo. Inika iziqinisekiso ezifanayo ze-77 ANSI / NSF njengezinye iinketho zethu ze-Aquasana kunye ne-AO Smith, kwaye inokubonelela nge-1.5 iilitha zamanzi ahlungiweyo ngomzuzu, ngaphezu kwezinye iimveliso. Umthamo olinganisiweyo wesihluzo ziigaloni ezingama-784, okanye malunga neenyanga ezintandathu zokusetyenziswa. Kodwa ayinaso isihluzi sentlenga yangaphambili, ngoko ke ukuba unengxaki yentlenga, ayilokhetho lulungileyo kuba iyakuvala. Kwaye inkulu kakhulu-20½ x 4½ intshi-ke ukuba i-sink cabinet yakho incinci okanye igcwele, isenokungafaneleki.
I-Aquasana AQ-5200 ifumene isiqinisekiso esingcolisekileyo, sifumaneka ngokubanzi, sinexabiso elifanelekileyo, kwaye sinesakhiwo esincinci. Yinkqubo yokuqala yokuhluza amanzi angaphantsi kwetanki esiyifunayo.
I-AO Smith AO-US-200 iyafana ne-Aquasana AQ-5200 ngokubhekiselele kwisatifikethi, iinkcukacha kunye nemilinganiselo. Yahlukile kwekaLowe kwaye ke ayifumaneki kakhulu.
I-AQ-5300 + inesatifikethi esifanayo esihle kakhulu, kodwa ngesantya esiphezulu sokuhamba kunye nomthamo wokuhluza, ifanelekile kumakhaya asebenzisa amanzi amaninzi, kodwa ixabiso liphezulu kwaye lithatha indawo engaphezulu phantsi kwe-sink.
I-Claryum Direct Connect ingafakelwa ngaphandle kokugrunjwa kwaye ihambise ukuya kuthi ga kwi-1.5 yeelitha zamanzi ahluziweyo ngomzuzu ngempompo yakho ekhoyo.
Ndivavanya izihluzi zamanzi kwi-Wirecutter ukusukela ngo-2016. Kwingxelo yam, bendinencoko eneenkcukacha kunye nombutho wokuqinisekisa izihluzi ukuze ndiqonde ukuba uvavanyo lwabo lwenziwa njani, kwaye ndaphonononga kwiziko ledatha likawonkewonke ukuze ndiqinisekise ukuba ingxelo yomenzi ixhaswe kuvavanyo lwesatifikethi. . Ndaye ndathetha nabameli beemveliso ezininzi zokucoca amanzi, kuquka i-Aquasana / AO Smith, iFiltrete, iBrita, kunye nePur, ukubabuza ukuba bathini. Kwaye ndiye ndazibonela ngokwam zonke iinketho zethu, kuba ukuhlala ngokupheleleyo, ukuqina kunye nobuhlobo bomsebenzisi kubaluleke kakhulu kwizixhobo ozisebenzisayo amaxesha amaninzi ngemini. Owayesakuba ngusosayensi we-NOAA uJohn Holecek uphande kwaye wabhala isikhokelo sokucoca amanzi sangaphambili seWirecutter, waziqhubela ezakhe iimvavanyo, wagunyazisa iimvavanyo ezingakumbi ezizimeleyo, kwaye wandifundisa okuninzi endikwaziyo. umsebenzi wam wakhelwe phezu kwesiseko sakhe.
Ngelishwa, akukho mpendulo efanayo malunga nokuba isihluzo samanzi siyafuneka. EUnited States, unikezelo lwamanzi lukawonke-wonke lulawulwa yi-EPA ngokuhambelana noMthetho waManzi aCocekileyo, kwaye iindawo zokucocwa kwamanzi ezishiya uluntu kufuneka zihlangabezane nemigangatho engqongqo yomgangatho. Kodwa ayizizo zonke izinto ezinokungcolisa ezinokuthi zilawuleke. Ngokufanayo, izinto ezingcolisayo zinokungena emanzini emva kokushiya iplanti yokucoca ngokungena okanye ngokuphuma kwimibhobho evuzayo (PDF). Ukucocwa kwamanzi okwenziwa (okanye ukungahoywa) kumzi-mveliso kunokwandisa ukuvuza kwimibhobho esezantsi-njengoko kwenzeka eFlint, eMichigan.
Ukuqonda ngokuchanekileyo izithako emanzini xa umthengisi eshiya i-factory, unokufumana ngokuqhelekileyo ingxelo yokuzithemba komthengi we-EPA yomthengisi wendawo kwi-Intanethi; ukuba akunjalo, bonke ababoneleli ngamanzi kufuneka bakubonelele ngeCCR yabo ngokweemfuno zakho. Nangona kunjalo, ngenxa yongcoliseko olunokubakho emazantsi omlambo, ekuphela kwendlela yokumisela ukubunjwa kwamanzi akho kukucela ilabhoratri yomgangatho wamanzi yendawo ukuba ivavanywe.
Ngokusekwe kumava: xa umdala indlu yakho okanye uluntu, kokukhona umngcipheko wongcoliseko olusezantsi. IArhente yoKhuseleko lweNdalo yaseUnited States yathi “izindlu ezazakhiwe ngaphambi kowe-1986 kusenokwenzeka ukuba zisebenzise imibhobho yelothe, izinto ezilungelelanisiweyo, kunye nesolder”—ezazifudula zixhaphakile ngezinto ezindala ezazingayifikeleli imilinganiselo yangoku. Ubudala bukwanyusa amathuba okungcoliseka kwamanzi aphantsi komhlaba ashiywe lishishini langaphambili lolawulo, elinokuba yingozi, ngakumbi xa zidityaniswe nokuthotywa okuhambelana nemibhobho egugayo engaphantsi komhlaba.
Ukuba usapho lwakho lusela ngaphezulu kweelitha ezimbini ukuya kwezintathu zamanzi okusela ngosuku, ngoko ke isihluzo esingaphantsi kwesinki sinokuba bhetele kunesihluzo setanki. Inkqubo ephantsi kwesitya ibonelela ngamanzi okusela ahluziweyo kwimfuno, ngaphandle kokulinda ukugqitywa kwenkqubo yokucoca, njengetanki lamanzi. Ukuhluzwa kwe-"On-demand" kuthetha ukuba inkqubo engaphantsi kwe-sink inokubonelela ngamanzi aneleyo okupheka-umzekelo, unokugcwalisa imbiza ngamanzi ahluziweyo ukupheka i-pasta, kodwa awuyi kuphinda uzalise imbiza ngokuphindaphindiweyo kule nto.
Xa kuthelekiswa nezihluzo ze-sink, ngaphantsi kwezihluzo ze-sink zikholisa ukuba nomthamo omkhulu kunye nobomi benkonzo ende-ngokuqhelekileyo amakhulu eegaloni kunye neenyanga ezintandathu nangaphezulu, ngelixa uninzi lwezihluzo ze-sink ziyi-40 yeegaloni kunye neenyanga ezimbini. Kuba izihluzi ezingaphantsi kwe-sink zisebenzisa uxinzelelo lwamanzi endaweni yomxhuzulane ukutyhala amanzi ngesihluzo, izihluzi zazo zinokuba xinene, ngoko ke zinokususa uluhlu olubanzi lwezinto ezinokuthi zingcolise.
Icala elisezantsi lelokuba zibiza kakhulu kunezihluzo zepitcher, kwaye ixabiso elipheleleyo kunye nexesha eliphakathi lokutshintsha izihluzi nazo zibiza kakhulu. Inkqubo iphinda ithathe indawo kwikhabhathi yesinki enokuthi isetyenziswe ukugcinwa.
Ukufakela isihluzi phantsi kwe-sink kufuna isiseko semibhobho kunye nofakelo lwe-hardware, kodwa lo msebenzi ulula kuphela ukuba isinki yakho sele inomngxuma wempompo owahlukileyo. Ukuba akunjalo, kufuneka unqonqoze indawo ye-faucet eyakhelwe-ngaphakathi (ungabona i-disc ephakanyisiweyo kwi-sink yensimbi, okanye uphawu kwi-synthetic stone sink). Ukuba umngxuma we-percussion awukho, kufuneka ugqobhoze umngxuma kwi-sink. Ukuba i-sink yakho ifakwe ezantsi, kufuneka kwakhona uqhube umngxuma kwi-countertop. Ukuba okwangoku unesepha, isithuba somoya kwi-dishwasher, okanye isitshizi esibanjwa ngesandla kwi-sink, ungasisusa kwaye usifake apho.
Emva kovavanyo, sitshintshe isihluzi esiyekiweyo sePur Pitcher ngesihluzo esiKhawulezayo sokugalela iPitcher.
Esi sikhokelo simalunga nodidi oluthile lwesihluzo esingaphantsi kwe-sink: abo basebenzisa i-cartridge filter kwaye bathumele amanzi ahluziweyo kwimpompo eyahlukileyo. Ezi zezona zihluzo zidumileyo ngaphantsi kwe-sink. Bathatha indawo encinci kakhulu kwaye ngokuqhelekileyo kulula ukuyifaka kunye nokugcina. Basebenzisa izixhobo ze-adsorbent-ngokuqhelekileyo i-carbon esebenzayo kunye ne-ion exchange resins, njengezihlungi zetanki zamanzi-ukubopha kunye nokunciphisa ukungcola. Asithethi ngezihluzi, iinkqubo ze-osmosis ezibuyela umva, okanye ezinye iipayiji okanye izinikezeli ezifakwe kwiimpompo.
Ukuqinisekisa ukuba sicebisa kuphela izihluzi ezithembekileyo, sihlala sigxininisa ukuba ukhetho lwethu luphumelele isiqinisekiso somgangatho weshishini: ANSI/NSF. I-American National Standards Institute kunye ne-NSF International yimibutho yabucala engenzi nzuzo esebenza kunye ne-EPA, abameli boshishino, kunye nezinye iingcali ukuseka imigangatho engqongqo yomgangatho kunye neeprothokholi zokuvavanya amawaka eemveliso, kuquka izihluzo zamanzi. Iilabhoratri ezimbini eziphambili zoqinisekiso lwabacoci bamanzi yiNSF International ngokwayo kunye noMbutho woMgangatho waManzi (WQA). Zombini zivunywe ngokupheleleyo yi-ANSI kunye neBhunga leMigangatho yaseCanada eNyakatho Melika, inokuvavanywa kwisatifikethi se-ANSI / NSF, kwaye zombini kufuneka ihambelane ngqo nemigangatho yovavanyo efanayo kunye neeprotocol. Isihluzi sinokuhlangabezana kuphela nemigangatho yesatifikethi emva kokuba sigqithise kakhulu ubomi obulindelweyo. Sebenzisa iisampulu ezilungisiweyo "ezingumngeni", ezingcoliseke kakhulu kunamanzi amaninzi etephu.
Kwesi sikhokelo, sigxile kwizihluzi ezineklorini, ilothe, kunye ne-VOC (i-volatile organic compound) iziqinisekiso.
Ukuqinisekiswa kwe-Chlorine (phantsi kwe-ANSI / i-Standard 42) ibalulekile kuba iklorini idla ngokuba ngunobangela ophambili "kwincasa embi" yamanzi empompo. Kodwa oku kuphantse kube yigimmick: phantse zonke iintlobo zezihluzi zamanzi zigqithise isiqinisekiso sayo.
Isiqinisekiso esikhokelayo kunzima ukusifezekisa kuba sithetha ukunciphisa izisombululo ezityebileyo ngelothe ngaphezulu kwe-99%.
Isiqinisekiso se-VOC sikwangumngeni kuba oko kuthetha ukuba isihluzi sinokususa ngaphezu kwe-50 ikhompawundi eziphilayo, kuquka ezininzi ze-biocides eziqhelekileyo kunye ne-precursors ye-industrial. Ayizizo zonke izihluzi ezingaphantsi kwesinki ezineziqinisekiso zibini, ke ngokujolisa kwizihluzi ezinezatifikethi ezibini, sichonge ezo zinokusebenza okuphezulu kakhulu.
Siye sacutha ukhangelo lwethu ngakumbi kwaye sakhetha izihluzi eziye zaqinisekiswa phantsi komgangatho omtsha we-ANSI/NSF 401, oquka ungcoliseko olusakhulayo, olufana neziyobisi, olufumaneka kumanzi aseMelika. Ngokufanayo, ayizizo zonke izihluzi ezinesatifikethi se-401, ngoko ke izihluzi ezinazo (kunye ne-lead kunye ne-VOC certification) liqela elikhethiweyo kakhulu.
Kweli candelo lingqongqo, emva koko sijonge abo banomthamo omncinci we-500 yeegaloni. Oku kulingana nobomi bokucoca malunga neenyanga ezi-6 phantsi kokusetyenziswa kakhulu (2¾ iigaloni ngosuku). Kwiintsapho ezininzi, oku kwanele ukuhlangabezana neemfuno zokusela kunye nokupheka imihla ngemihla. (Umvelisi ubonelela ngeshedyuli ecetyiswayo yokutshintsha isihluzi, ngesiqhelo kwiinyanga kuneegaloni; silandela ezi ngcebiso kuvavanyo lwethu kunye nokubalwa kweendleko. Sicebisa ngalo lonke ixesha kufakwe umenzi woqobo endaweni yesihluzo somntu wesithathu. )
Ekugqibeleni, silinganise iindleko zangaphambili zenkqubo yonke kunye neendleko eziqhubekayo zokutshintsha isihluzo. Asimiselanga xabiso lisezantsi okanye eliphezulu, kodwa uphando lwethu lubonisa ukuba nangona ixabiso langaphambili lisuka kwi-US$100 ukuya kwi-US$1,250, kwaye iindleko zokucoca zisuka kwi-US$60 ukuya phantse kwi-US$300, lo mahluko awukho ngaphezulu kakhulu. Imodeli ebiza kakhulu kwiinkcukacha. Sifumene iindidi ezininzi zeefilitha ezingaphantsi kwe-sinki ezibiza kakuhle ngaphantsi kwe-US$200, ngelixa zibonelela ngesatifikethi esigqwesileyo kunye nobomi obude. Aba baye baba ngabagqwesileyo bethu. Ukongeza, sikwajonge:
Ngexesha lophando, ngamanye amaxesha siye sadibana neengxelo zokuvuza eziyingozi ezivela kumnini wesihluzo samanzi phantsi kwe-sink. Ekubeni isihluzo sidityaniswe kumbhobho wokungena wamanzi abandayo ngombhobho, ukuba isiqhagamshelanisi okanye umbhobho wophukile, amanzi aya kubaleka de ivalve yokuvala ivalwe-nto leyo ethetha ukuba kungathatha iiyure okanye iintsuku ukuba ufumanise. ingxaki, eya kukunika Zisa iziphumo ezibi. Umonakalo wamanzi. Oku akuqhelekanga, kodwa kufuneka ulinganise iingozi xa ucinga ukuthenga isihluzo phantsi kwe-sink. Ukuba uyayithenga, nceda ulandele imiyalelo yofakelo ngononophelo, unakekele ukuba ungaweli imisonto yesidibanisi, uze uvule ngokucothayo amanzi ukujonga ukuvuza.
Isihluzo se-osmosis esingemva okanye i-R/O isihluzo ekuqaleni sasisebenzisa uhlobo olufanayo lwesihluzo sekhatriji njengoko sikhethe apha, kodwa songeze indlela yesibini yokuhluza i-osmosis: inwebu ecolekileyo evumela amanzi ukuba adlule kodwa ihluze iiminerali ezinyityilisiweyo. Izinto kunye nezinye izinto.
Singaxoxa ngezihluzi ze-R/O nzulu kwizikhokelo ezizayo. Apha, sabakhaba ngokupheleleyo. Xa kuthelekiswa nezihluzo ze-adsorption, zibonelela ngeenzuzo ezilinganiselweyo zokusebenza; bavelisa amanzi amaninzi amdaka (ngokuqhelekileyo iilitha ezi-4 zamanzi "agungxulwayo" achithwayo kwi-gallon yokucoca), ngelixa izihlungi ze-adsorption zingenzi; bathatha indawo Inkulu kakhulu kuba, ngokungafaniyo nezihluzi ze-adsorption, zisebenzisa i-gallon e-1 okanye iitanki ezi-2 zokugcina amanzi ahluziweyo; zicotha kakhulu kunezihluzo ze-adsorption phantsi kwe-sink.
Kule minyaka imbalwa idlulileyo, siye saqhuba iimvavanyo zaselebhu kwizihluzo zamanzi. Isiphelo esiphambili esisithathileyo kwiimvavanyo kukuba isiqinisekiso se-ANSI/NSF ngumlinganiselo othembekileyo wokusebenza kohluzo. Ngenxa yokuqina okugqithisileyo kovavanyo lwesatifikethi, oku akumangalisi. Ukusukela ngoko, siye sathembela kwisatifikethi se-ANSI/NSF endaweni yovavanyo lwethu olulinganiselweyo ukukhetha abo sikhuphisana nabo.
Ngo-2018, sivavanye inkqubo yokucoca amanzi e-Big Berkey eyaziwayo, engazange iqinisekiswe yi-ANSI / NSF, kodwa ithi ihlolwe ngokubanzi ngokuhambelana nemigangatho ye-ANSI / NSF. Loo mava aqinise ngakumbi ukunyanzeliswa kwethu kwisiqinisekiso sokwenyani se-ANSI/NSF kunye nokungathembi kwethu ingxelo “ye-ANSI/NSF ivavanyiwe”.
Ukusukela ngoko, kubandakanywa no-2019, iimvavanyo zethu zigxile kusetyenziso lwehlabathi lokwenyani kunye neempawu ezahlukeneyo ezisebenzayo kunye nokusilela okuya kubonakala xa usebenzisa ezi mveliso.
I-Aquasana AQ-5200 ifumene isiqinisekiso esingcolisekileyo, sifumaneka ngokubanzi, sinexabiso elifanelekileyo, kwaye sinesakhiwo esincinci. Yinkqubo yokuqala yokuhluza amanzi angaphantsi kwetanki esiyifunayo.
Sakhetha i-Aquasana AQ-5200, eyaziwa ngokuba yi-Aquasana Claryum Dual-Stage. Ukuza kuthi ga ngoku, eyona nto ibaluleke kakhulu kukuba isihluzo saso sifumene isiqinisekiso se-ANSI / NSF esingcono kakhulu phakathi kwabakhuphisana nabo, kuquka i-chlorine, i-chloramine, i-lead, i-mercury, i-VOC, iindidi "zokungcola okuvelayo", kunye ne-perfluorooctanoic acid kunye ne-Perfluorooctane sulfonic acid. Ukongeza, itephu kunye nezixhobo zemibhobho zemibhobho zenziwe ngentsimbi eyomeleleyo, ebhetele kuneeplastiki ezisetyenziswa ngabanye abavelisi. Kwaye le nkqubo nayo ixinene kakhulu. Ekugqibeleni, i-Aquasana AQ-5200 yenye yeemveliso ezixabisekileyo esizifumene kwisihlunu phantsi kwe-sink. Iindleko ezihlawulwa kwangaphambili zenkqubo yonke (isihluzo, indlu, itephu kunye nehardware) idla ngokuba yi-US$140, kwaye ezimbini zii-US$60. Buyisela isihluzi. Oku kungaphantsi kwabakhuphisana abaninzi abanezatifikethi ezibuthathaka.
I-Aquasana AQ-5200 idlulile isiqinisekiso se-ANSI / NSF (PDF) kwaye inokusingatha izinto ezingcolileyo ze-77. Kanye kunye ne-Aquasana AQ-5300 + efanayo eqinisekisiweyo kunye ne-AO Smith AO-US-200, oku kwenza i-AQ-5200 ibe yeyona nkqubo inamandla yokuqinisekisa esisikhethayo. (I-AO Smith ifumene i-Aquasana kwi-2016 kwaye yamkele ininzi yeteknoloji yayo; U-AO Smith akanalo izicwangciso zokuphelisa uchungechunge lwe-Aquasana.) Ngokwahlukileyo, i-Pur Pitcher Filter egqwesileyo kunye nokuNcitshiswa kweNkokeli iqinisekisiwe kwi-23.
Ezi ziqinisekiso ziquka iklorini, esetyenziselwa ukubulala iintsholongwane kumanzi kamasipala kwaye ngoyena nobangela “wokunuka” kwamanzi empompo; i-lead, enokuthi ikhutshwe kwimibhobho endala kunye ne-solder yombhobho; imekyuri phila Cryptosporidium kunye Giardia , Iintsholongwane ezimbini ezinokubakho; I-chloramine sisibulali-ntsholongwane se-chloramine esizingileyo, esisetyenziswa kakhulu kwizityalo zokuhluza kumazantsi e-United States, apho i-chlorine ecocekileyo iya kuthotywa ngokukhawuleza emanzini afudumeleyo. I-Aquasana AQ-5200 iphinde idlulise isatifikethi se-15 "ezingcolileyo ezikhulayo", ezikhulayo kwiinkqubo zokubonelela ngamanzi kawonkewonke, kuquka i-bisphenol A, ibuprofen, kunye ne-estrone (i-estrogen esetyenziselwa ukukhulelwa); Kwi-PFOA kunye ne-PFOS-fluorine-based based compounds esetyenziselwa ukwenza izinto ezingenanto, kwaye ifumene isiluleko sezempilo se-EPA ngoFebruwari 2019. (Ngexesha lokubonisana, kuphela abavelisi abathathu bolu hlobo lwesihluzi baye bafumana isatifikethi se-PFOA / S, esiye safumana isiqinisekiso se-PFOA / S. yenza oku kuphawuleke ngokukodwa.) Ikwapasile nesatifikethi se-VOC. Oku kuthetha ukuba inokususa ngokufanelekileyo ngaphezu kwe-50 yeekhompawundi ezahlukeneyo ze-organic, kubandakanywa izitshabalalisi ezininzi kunye ne-industrial precursors.
Ukongeza kwi-carbon esebenzayo kunye ne-ion exchange resins (uninzi, ukuba alukho zonke, izihlungi ezingaphantsi kwetanki ziqhelekileyo), i-Aquasana isebenzisa iteknoloji ezimbini ezongezelelweyo zokucoca ukufumana isatifikethi. Kwi-chloramines, yongeza i-catalytic carbon, eyona ndlela i-porous ye-carbon activated eyenziwa ngokuphatha i-carbon kunye ne-high-temperature gas. I-Cryptosporidium kunye ne-Giardia, i-Aquasana yenza izihlungi ngokunciphisa ubungakanani be-pore ukuya kwi-0.5 microns, eyaneleyo ukubamba ngokwenyama.
Isiqinisekiso esigqwesileyo sesihluzo se-Aquasana AQ-5200 sesona sizathu siyikhethileyo. Kodwa uyilo lwayo kunye nezixhobo ziyenza ibe yodwa. I-faucet yenziwe ngesinyithi esomeleleyo, njengoko kunjalo ne-T-shaped fixture edibanisa isihluzo kumbhobho. Abanye abakhuphisana nabo basebenzisa iplastiki enye okanye ezimbini kubo, ukunciphisa iindleko, kodwa ukwandisa umngcipheko we-thread cross-threading kunye neempazamo zofakelo. I-AQ-5200 isebenzisa i-compression fittings ukuqinisekisa isitywina esiqinileyo nesikhuselekileyo phakathi kombhobho wakho kunye nombhobho weplastiki ohambisa amanzi kwisihluzo kunye ne-faucet; abanye abakhuphisana nabo basebenzisa izixhobo ezilula zokutyhala, ezingakhuselekanga kakhulu. I-AQ-5200 faucet ifumaneka kwii-finals ezintathu (i-nickel e-brushed, i-chrome epholisiweyo kunye ne-oiled bronze), kwaye abanye abakhuphisana nabo abanakukhetha.
Sikwathanda i-compact form factor yenkqubo ye-AQ-5200. Isebenzisa iperi yezihluzi, nganye kuzo inkulu kancinane kunetoti yesoda; ezinye izihluzi, kuquka i-Aquasana AQ-5300+ engezantsi, ubukhulu bebhotile yelitha. Emva kokufaka isihluzo kwi-bracket yokufaka, imilinganiselo ye-AQ-5200 i-9 intshi ukuphakama, i-8 intshi ububanzi, kunye ne-4 intshi ubunzulu; I-Aquasana AQ-5300+ yi-13 x 12 x 4 intshi. Oku kuthetha ukuba i-AQ-5200 ithatha indawo encinci kakhulu kwikhabhinethi ye-sink, inokufakwa kwindawo emxinwa engakwazi ukufakwa kwiinkqubo ezinkulu, kwaye ishiya indawo eninzi yokugcina phantsi kwesitya. Udinga malunga ne-intshizi ezili-11 zesithuba esithe nkqo (esilinganiswe ezantsi ukusuka phezulu kwendawo ebiyelweyo) ukuvumela isihluzo ukuba sitshintshwe, kwaye malunga ne-intshizi ezili-9 zesithuba esithe tye esingavalelwanga ecaleni kodonga lwekhabhathi yokufaka indawo ebiyelweyo.
I-AQ-5200 ihlaziywe kakuhle kwiifilitha zamanzi, kunye neenkwenkwezi ze-4.5 ngaphandle kokuphononongwa okungaphezulu kwe-800 kwiwebhusayithi ye-Aquasana (ngaphandle kweenkwenkwezi ezintlanu), kunye neenkwenkwezi ze-4.5 malunga nokuhlaziywa kwe-500 kwi-Home Depot.

I-Aquasana AQ- I-5200 yenye yezona mveliso zibaluleke kakhulu sikhuphisana nabo, amakhulu eedola atshiphu ngexabiso eliphantsi kuneminye imifuziselo eqinisekisiweyo. Isixhobo sibandakanya isibali-xesha esiya kuqalisa ukubeep xa ufuna ukutshintsha isihluzo, kodwa sicebisa ukuba usete isikhumbuzi sekhalenda esiphinda kwifowuni yakho. (Akunakwenzeka ukuba uyiphose.)
Xa kuthelekiswa nabanye abakhuphisana nabo, i-Aquasana AQ-5200 inomlinganiselo ophantsi wokuhamba okuphezulu (0.5 gpm vs. 0.72 okanye ngaphezulu) kunye nomthamo ophantsi (ii-500 iilitha vs. 750 okanye ngaphezulu). Esi sisiphumo esithe ngqo sesihluzo saso esincinci ngokwasemzimbeni. Ngokubanzi, sikholelwa ukuba ezi ntsilelo zincinci zilungiswa kukubumbana kwayo. Ukuba uyazi ukuba ufuna ukuhamba okuphezulu kunye nomthamo, i-Aquasana AQ-5300 + ine-flow rated flow of 0.72 gpm kunye ne-800 galoni, kodwa kunye neshedyuli efanayo yokutshintsha isihluzo seenyanga ezintandathu, i-Aquasana Claryum Direct Connect inezinga lokuhamba ukuya kuthi ga kwi-1.5. gpm kwaye Ilinganiswe kwi-784 iigaloni kunye neenyanga ezintandathu.
