Kugulitsa kwa Amazon mu Okutobala kukupitirira. Kuti mudziwe zambiri zokhudza mapangano a Wirecutter omwe ndi ofunika kugula, onani mndandanda wathu wa mapangano abwino kwambiri a Prime Day.
Aliyense amene amamwa madzi ochulukirapo pa tsiku adzakhutira kwambiri ndi makina osefera pansi pa sinki monga Aquasana AQ-5200. Mosiyana ndi jug, fyuluta pansi pa sinki imapereka madzi nthawi zonse akafuna. Tikukulimbikitsani kugwiritsa ntchito Aquasana AQ-5200 chifukwa ziphaso zake ndi zabwino kwambiri kuposa njira ina iliyonse yomwe tapeza; zimaphatikizapo (monga njira zina zonse zomwe tapeza pano) chlorine, lead, mercury, PFAS, mitundu yosiyanasiyana ya mankhwala ophera tizilombo, ndi microplastics.
Aquasana AQ-5200 ndi yovomerezeka ndi ANSI/NSF ndipo imatha kuchotsa zinthu zambiri zodetsa, kuphatikizapo lead, mercury, mankhwala ophera tizilombo, microplastics, mankhwala ndi zinthu zina zomwe opikisana nawo ochepa angatenge. Ndi imodzi mwa zosefera zochepa zomwe zili ndi PFOA ndi PFOS, mankhwala awiri osatha omwe amadetsa nkhawa bungwe la Environmental Protection Agency.
Mtengo wosintha zosefera ndi pafupifupi $60, kapena $120 pachaka, kutengera nthawi yosinthira ya miyezi isanu ndi umodzi yomwe Aquasana amalangiza. Ndipo makinawa ndi akulu pang'ono kuposa zitini zingapo za soda, kotero satenga malo ambiri ofunika pansi pa sinki. Ili ndi zitsulo zapamwamba kwambiri ndipo ma faucet amapezeka m'mitundu yosiyanasiyana.
AO Smith AO-US-200 ndi yofanana ndi Aquasana AQ-5200 m'mbali zonse zofunika. (Izi zili choncho chifukwa AO Smith adagula Aquasana mu 2016.) Ili ndi zinthu zomwezo zapamwamba, zida zachitsulo zonse, komanso mawonekedwe ang'onoang'ono, koma popeza imagulitsidwa ku Lowe's kokha, siipezeka kwambiri ndipo ma faucet ake ali ndi kumaliza kamodzi kokha. : nickel yopukutidwa. Ndalama zosinthira zosefera ndizofanana: pafupifupi $60 pa seti iliyonse, kapena $120 pachaka pa miyezi isanu ndi umodzi yomwe AO Smith adalimbikitsa.
Ili ndi ziphaso zabwino kwambiri monga AQ-5200, komanso mphamvu zambiri zoyendera ndi kusefera kuposa AQ-5200, komanso fyuluta yoyambira kuchotsa dzimbiri.
Aquasana AQ-5300+ Max Flow ili ndi ziphaso zabwino kwambiri monga zomwe tasankha, koma imapereka madzi ambiri (0.72 gpm vs. 0.5 gpm) ndi mphamvu yosefera (800 gpm vs. 500). Izi zimapangitsa kuti ikhale njira yoyenera kwa mabanja omwe amafunikira madzi ambiri osefedwa ndipo amawafuna mwachangu momwe angathere. Imawonjezeranso sediment pre-filter yomwe AQ-5200 ilibe; izi zitha kukulitsa sediment fyuluta pamadzi ambiri m'nyumba zomwe zili ndi madzi ambiri osungunuka. Komabe, AQ-5300+ (yokhala ndi mafyuluta akuluakulu ngati botolo la malita atatu) ndi yayikulu kwambiri kuposa AQ-5200, ndipo ndalama zoyambira ndi zosinthira fyuluta ndizokwera pang'ono (pafupifupi $80 pa seti iliyonse kapena $160 pachaka).
Imayikidwa popanda kuboola ndipo imapereka madzi osefedwa okwana malita 1.5 pa mphindi imodzi kudzera m'mapaipi omwe alipo.
Claryum Direct Connect ya Aquasana imalumikizana mwachindunji ndi ma faucet omwe alipo, zomwe zimapangitsa kuti ikhale njira yokongola kwambiri kwa obwereka (omwe angakhale oletsedwa kusuntha) ndi omwe sangathe kuyika faucet yosiyana. Siyeneranso kuyikidwa pakhoma la kabati pansi pa sinki, imangoima pambali pake. Ili ndi ziphaso zofanana za ANSI/NSF monga mitundu ina ya Aquasana ndi AO Smith ndipo imatha kupereka magaloni 1.5 a madzi osefedwa pamphindi. Fyuluta iyi ili ndi mphamvu yokwana magaloni 784 ndipo iyenera kukhala pafupifupi miyezi isanu ndi umodzi. Koma ilibe sediment pre-filter. Chifukwa chake, ngati muli ndi vuto ndi sediment, iyi si njira yabwino kwambiri chifukwa imatha kutsekeka mosavuta. Ndipo ndi yayikulu—20.5 x 4.5 mainchesi—kotero ngati sinki yanu ndi yaying'ono kapena yodzaza kwambiri, singakwane.
Ili ndi ziphaso zabwino kwambiri monga AQ-5200, komanso mphamvu zambiri zoyendera ndi kusefera kuposa AQ-5200, komanso fyuluta yoyambira kuchotsa dzimbiri.
Imayikidwa popanda kuboola ndipo imapereka madzi osefedwa okwana malita 1.5 pa mphindi imodzi kudzera m'mapaipi omwe alipo.
Ndakhala ndikuyesa zosefera madzi za Wirecutter kuyambira mu 2016. Mu lipoti langa, ndalankhula mwatsatanetsatane ndi mabungwe opereka chitsimikizo cha zosefera kuti ndimvetse momwe mayeso awo amachitikira, ndipo ndafufuza m'ma database awo aboma kuti nditsimikizire kuti zomwe opanga amanena zikuthandizidwa ndi: Kuyesa kovomerezeka. Ndalankhulanso ndi oimira opanga zosefera madzi angapo, kuphatikiza Aquasana/AO Smith, Filtrete, Brita ndi Pur, kuti nditsutse zomwe akunena. Ine ndekha ndayesa njira zathu zonse chifukwa kudalirika konse, kulimba, ndi kugwiritsidwa ntchito ndikofunikira kwambiri pa chipangizo chomwe chimagwiritsidwa ntchito kangapo patsiku.
Wasayansi wakale wa NOAA, John Holecek, adafufuza ndikulemba buku loyamba la Wirecutter water filter, adachita mayeso akeake, adalamula mayeso ena odziyimira pawokha, ndipo adandiphunzitsa zambiri zomwe ndikudziwa. Ntchito yanga imachokera pa ntchito yake.
Mwatsoka, palibe yankho lachindunji pa funso lakuti ngati mukufuna fyuluta yamadzi kapena ayi. Ku United States, madzi a anthu onse amayendetsedwa ndi bungwe la US Environmental Protection Agency motsatira lamulo la Clean Water Act, ndipo madzi ochokera m'malo oyeretsera madzi a anthu onse ayenera kukwaniritsa miyezo yokhwima. Koma si zinthu zonse zodetsa zomwe zingachitike zomwe zimayendetsedwa. Kuphatikiza apo, zinthu zodetsa zimatha kulowa m'madzi atatuluka m'malo oyeretsera, kaya kudzera m'mapaipi otuluka (PDF) kapena mwa kutuluka m'mapaipi okha. Kuyeretsa madzi komwe kumachitika (kapena kunyalanyazidwa) pafakitale kungapangitse kuti kutuluka kwa madzi m'mapaipi otsika, monga momwe zinachitikira ku Flint, Michigan.
Kuti mudziwe zomwe zili m'madzi a ogulitsa anu, nthawi zambiri mutha kufufuza pa intaneti lipoti lodalirika la ogula la ogulitsa anu la EPA; apo ayi, ogulitsa madzi onse a anthu onse ayenera kukupatsani ma CCR awo akafunsidwa. Koma chifukwa cha kuipitsidwa komwe kungachitike pambuyo pake, njira yokhayo yodziwira zomwe zili m'madzi a m'nyumba mwanu ndi kulipira labotale yamtundu wa madzi kuti ayesere.
Kawirikawiri, nyumba yanu kapena dera lanu likakula, chiopsezo cha kuipitsidwa kwa madzi m'madzi chimakhala chachikulu. Bungwe la Environmental Protection Agency linanena kuti “nyumba zomwe zinamangidwa isanafike chaka cha 1986 zimakhala ndi mapaipi a lead, zida zomangira ndi solder”—zipangizo zakale, zomwe kale zinali zofala zomwe sizikugwirizana ndi malamulo amakono. Ukalamba umawonjezeranso mwayi woipitsidwa kwa madzi apansi panthaka okalamba ndi mafakitale omwe kale ankalamulidwa, zomwe zingakhale zoopsa, makamaka zikaphatikizidwa ndi kuwonongeka kwa mapaipi apansi panthaka chifukwa cha ukalamba.
Ngati banja lanu limagwiritsa ntchito madzi opitilira malita awiri kapena atatu a madzi akumwa patsiku, fyuluta yamadzi yosalowa m'madzi ingakhale chisankho chabwino kuposa fyuluta ya mtsuko. Makina osalowa m'madzi amapereka madzi osefedwa nthawi iliyonse akafuna, zomwe zimapangitsa kuti pasakhale kudikira kuti njira yosefedwa ithe monga momwe zimakhalira ndi mtsuko. Kusefa nthawi iliyonse kumatanthauzanso kuti makina osalowa m'madzi angapereke madzi okwanira ophikira—mwachitsanzo, mutha kudzaza mphika ndi madzi osefedwa kuti muphike pasitala, koma simudzafunika kudzazanso mtsukowo pachifukwa chimenecho.
Poyerekeza ndi zosefera za pitcher, zosefera za under-sink nthawi zambiri zimakhala ndi mphamvu yayikulu komanso nthawi yayitali—nthawi zambiri zimakhala magaloni mazana angapo ndi miyezi isanu ndi umodzi kapena kuposerapo poyerekeza ndi kukula kwa magaloni 40 a zosefera zambiri za pitcher ndi miyezi iwiri. Chifukwa zosefera za under-sink zimagwiritsa ntchito mphamvu ya madzi m'malo mwa mphamvu yokoka kuti zikankhire madzi mu fyuluta, zosefera zawo zimatha kukhala zokhuthala kwambiri motero zimachotsa zinthu zambiri zomwe zingadetse.
Vuto lake ndilakuti zimakhala zodula kwambiri kutsogolo kuposa zosefera za pitcher, ndipo zosefera zina zimakhala zodula kwambiri malinga ndi momwe zinthu zilili komanso pa avareji pakapita nthawi. Dongosololi limatenganso malo a makabati pansi pa sinki omwe akanatha kugwiritsidwa ntchito posungira.
Kuyika fyuluta pansi pa sinki kumafuna kukhazikitsa mapaipi ndi zida zoyambira, koma ntchitoyi ndi yosavuta ngati sinki yanu ili kale ndi mpata wa pompo ina. Apo ayi, muyenera kuchotsa malo amodzi a pompo omwe ali mkati mwake (diski yokwezedwa pa sinki yachitsulo kapena chizindikiro pa sinki yopangidwa ndi miyala). Ngati mulibe dzenje lotulukira, muyenera kuboola dzenje mu sinki kapena pa kauntala ngati sinki yanu ilibe malo okwanira. Ngati muli ndi chotsukira sopo kapena chopopera ndi manja pa sinki yanu, mutha kuchichotsa ndikuyika pompo. (Musayike pompo pomwe pali mpata wa mpweya - izi ndi kuteteza madzi odetsedwa kuti asalowe mu chotsukira mbale.)
Pafupifupi theka la madzi onse apampopi ali ndi mankhwala osatha. Umu ndi momwe mungadziwire ngati muli pachiwopsezo ndikuchepetsa kukhudzana ndi madzi.
Bukuli likunena za mtundu winawake wa fyuluta ya pansi pa sinki: yomwe imagwiritsa ntchito fyuluta ya cartridge. Imatenga malo ochepa kwambiri ndipo nthawi zambiri imakhala yosavuta kuyiyika ndi kusamalira. Imagwiritsa ntchito zinthu zokoka (nthawi zambiri ma resins osinthika a kaboni ndi ma ion monga ma fyuluta a pitcher) kuti imange ndikuchotsa zodetsa. Zambiri zimayikidwa pa faucet yosiyana (yophatikizidwa), zomwe zikutanthauza kuti mudzafunika dzenje lokwezera pa kauntala; Dzenje lopangidwira payipi yopopera lidzagwira ntchito, kapena mutha kuboola dzenje latsopano. Sitikulankhula za ma fyuluta oyika faucet, makina osinthira osmosis, kapena ma pitcher ena amadzi kapena zotulutsira madzi.
Kuti tiwonetsetse kuti tikupangira mafyuluta okha omwe mungawadalire, nthawi zonse timaumirira kuti zomwe tasankha zikhale zovomerezeka malinga ndi muyezo wamakampani: ANSI/NSF. American National Standards Institute ndi NSF International ndi mabungwe achinsinsi, osachita phindu omwe amagwira ntchito ndi Environmental Protection Agency, makampani ndi akatswiri ena kuti apange miyezo yokhwima yaubwino ndi njira zoyesera zinthu zambirimbiri, kuphatikizapo mafyuluta amadzi. Ma laboratories awiri akuluakulu otsimikizira mafyuluta amadzi ndi NSF International yokha ndi Water Quality Association (WQA). Zinthu zonsezi ndizovomerezeka mokwanira ndi ANSI ndi Canadian Standards Council ku North America kuti ziyesedwe za ANSI/NSF, ndipo zonse ziyenera kutsatira miyezo yomweyo ndi njira zoyesera. Pambuyo pogwiritsa ntchito zitsanzo zokonzedwa "zoyesera", zomwe zinali zodetsedwa kwambiri kuposa madzi ambiri apampopi, fyulutayo idapitilira nthawi yayitali kuposa momwe imayembekezeredwa ndipo idakwaniritsa miyezo ya certification.
Mu bukhuli, tiyang'ana kwambiri pa zosefera zomwe zili ndi ziphaso za chlorine, lead, ndi volatile organic compounds (VOCs).
Chitsimikizo cha chlorine n'chofunika chifukwa chlorine ndiye chinthu chofala chomwe chimayambitsa "fungo loipa" m'madzi apampopi. Koma izi ndi zabwino kwambiri: pafupifupi mitundu yonse ya zosefera madzi ndi zovomerezeka.
Kupeza satifiketi ya lead ndi kovuta chifukwa kumatanthauza kuchepetsa mayankho okhala ndi lead ndi zoposa 99%.
Chitsimikizo cha VOC chilinso chovuta chifukwa zikutanthauza kuti fyuluta imatha kuchotsa mankhwala opitilira 50 achilengedwe, kuphatikiza mankhwala ambiri odziwika bwino komanso zinthu zoyambira mafakitale. Si zosefera zonse zomwe zili pansi pa sinki zomwe zili ndi zitsimikizo zonse ziwiri, kotero poyang'ana kwambiri zosefera zomwe zili ndi zitsimikizo zonse ziwiri, tapeza zosefera zomwe zimagwira ntchito bwino kwambiri.
Tinachepetsa kufufuza kwathu ndipo tinasankha zosefera ndi ziphaso zina ku muyezo watsopano wa ANSI/NSF 401, womwe umaphimba zinthu zodetsa zomwe zikupezeka m'madzi ku United States, monga mankhwala. Momwemonso, si zosefera zonse zomwe zili ndi ziphaso za 401. Chifukwa chake, malo omwe ali ndi ziphaso za 401 (komanso lead ndi VOC) ali mgulu losankhidwa mosamala.
Kenako, mkati mwa gawo lokhazikika ili, timafunafuna zinthu zokhala ndi mphamvu yochepera magaloni 500. Izi zikufanana ndi miyezi isanu ndi umodzi ya moyo wa fyuluta pogwiritsa ntchito kwambiri (magaloni 2.75 patsiku). Madzi osefedwa awa ndi okwanira mabanja ambiri kumwa ndi kuphika tsiku ndi tsiku. (Opanga amapereka ndondomeko zovomerezeka zosinthira fyuluta, nthawi zambiri m'miyezi osati m'magaloni; timatsatira malangizo awa mu ziwerengero zathu ndi kuwerengera mtengo. Timalimbikitsa nthawi zonse kugwiritsa ntchito zida zosinthira zopangidwa ndi opanga m'malo mwa zosefera za chipani chachitatu.)
Pamapeto pake, tinayesa mtengo woyamba wa makina onsewa poyerekeza ndi mtengo womwe ulipo wosintha zosefera. Sitinakhazikitse mtengo kapena denga, koma kafukufuku wathu wasonyeza kuti ngakhale mtengo woyamba unali pakati pa $100 ndi $1,250 ndipo mtengo wa zosefera unali pakati pa $60 ndi pafupifupi $300, kusiyana kumeneku sikunatanthauze kuti ntchito yabwino kwambiri. Mitundu yokwera mtengo kwambiri. Tapeza zosefera zingapo zomwe zimakhala pansi pa sinki zomwe zimawononga ndalama zosakwana $200 koma zili ndi ziphaso zabwino komanso kulimba. Awa ndi anthu omwe adakhala omaliza athu. Pakati pa zinthu zina zomwe tikuyang'ana:
Pa kafukufuku wathu, nthawi zina timalandira malipoti okhudza kutuluka kwa madzi koopsa kuchokera kwa eni ake a zosefera zamadzi zomwe zili pansi pa sinki. Chifukwa chakuti fyulutayo imalumikizidwa ndi madzi ozizira, ngati cholumikizira kapena payipi yasweka, madzi amatha kutuluka mpaka valavu yotseka itatsekedwa, kotero zingatenge maola kapena masiku kuti mudziwe vutoli, zomwe zingakubweretsereni mavuto aakulu. Kuwonongeka kwa madzi. Sizachilendo, koma mukaganizira zogula fyuluta yomwe ili pansi pa sinki, muyenera kuwunika zoopsa. Ngati mwagula imodzi, tsatirani malangizo oyika mosamala, samalani kuti musapotoze zolumikizira molakwika, kenako pang'onopang'ono muyatsenso madziwo kuti muwone ngati akutuluka. Kuti mukhale ndi mtendere wamumtima (kuthetsa mavuto anu onse a mapaipi, osati fyuluta yomwe ili pansi pa sinki yokha), ganizirani kuyika chowunikira chanzeru chotulutsa madzi.
Zosefera za reverse osmosis (R/O) poyamba zimakhala ndi mtundu womwewo wa cartridge filter monga womwe tidasankha pano, koma onjezani njira yachiwiri yosefera reverse osmosis: nembanemba yokhala ndi mabowo ochepa yomwe imalola madzi kudutsa koma imasefera mchere wosungunuka ndi zinthu zina.
Tikhoza kukambirana zambiri za zosefera za R/O mwatsatanetsatane mu phunziro la mtsogolo. Apa tikuzikana kwathunthu. Zili ndi ubwino wochepa poyerekeza ndi zosefera za adsorption; zimapanga madzi ambiri otayira (nthawi zambiri magaloni 4 a madzi otayira "osambitsa" pa galoni iliyonse yosefedwa), pomwe zosefera za adsorption sizipanga madzi otayira; Zimatenga malo ambiri chifukwa, mosiyana ndi zosefera za adsorption, zimagwiritsa ntchito thanki ya galoni imodzi kapena ziwiri kusungira madzi osefedwa; ndipo zimagwira ntchito pang'onopang'ono kuposa zosefera za adsorption zomwe zili pansi pa sinki.
Kwa zaka zingapo zapitazi takhala tikuyesera zosefera madzi m'ma laboratories, ndipo mfundo yaikulu yochokera mu mayeso athu ndi yakuti satifiketi ya ANSI/NSF ndi chizindikiro chodalirika cha magwiridwe antchito a zosefera. Izi sizosadabwitsa chifukwa cha kukhwima kwa mayeso a satifiketi. Kuyambira pamenepo, tadalira satifiketi ya ANSI/NSF kusankha opikisana nawo m'malo mongoyesa zathu zochepa.
Mu 2018, tinayesa njira yotchuka yosefera madzi ya Big Berkey, yomwe siili ndi satifiketi ya ANSI/NSF koma imati yayesedwa kwambiri kuti ikwaniritse miyezo ya ANSI/NSF. Izi zinalimbitsa kudzipereka kwathu ku satifiketi yeniyeni ya ANSI/NSF komanso kusakhulupirira kwathu zonena za "ANSI/NSF Verified".
Kuyambira pamenepo, kuphatikizapo mu 2019, mayeso athu akuyang'ana kwambiri momwe zinthu zingakhalire zogwiritsidwa ntchito komanso zinthu zothandiza komanso zofooka zomwe zimaonekera mukamagwiritsa ntchito zinthuzi.
Tinasankha Aquasana AQ-5200, yomwe imadziwikanso kuti Aquasana Claryum Dual-Stage. Chofunika kwambiri ndichakuti zosefera zake zili ndi ziphaso zabwino kwambiri za ANSI/NSF pakati pa opikisana nawo athu za chlorine, chloramines, lead, mercury, VOCs, "zonyansa zambiri zomwe zikubwera," microplastics, ndi PFOA ndi PFOS. Kuphatikiza apo, ma faucet ndi zida zake zimapangidwa ndi chitsulo cholimba, chomwe chili bwino kuposa pulasitiki yomwe imagwiritsidwa ntchito ndi opanga ena. Kuphatikiza apo, dongosololi ndi laling'ono kwambiri. Pamapeto pake, Aquasana AQ-5200 ndi imodzi mwa njira zabwino kwambiri zomwe tapeza pazosefera pansi pa sinki, ndi dongosolo lonse (fyuluta, nyumba, faucet, ndi zida) nthawi zambiri zimawononga pafupifupi $140 patsogolo kapena seti ya seti ziwiri. m'malo mwa fyuluta ndi $60. Izi ndi zochepa kuposa opikisana nawo ambiri omwe ali ndi ziphaso zofooka.
Chitsimikizo cha ANSI/NSF (PDF) cha AQ-5200 Chili ndi chlorine, yomwe imagwiritsidwa ntchito kupha tizilombo toyambitsa matenda m'madzi a m'matauni ndipo ndiye chifukwa chachikulu cha "fungo loipa" m'madzi apampopi; lead, yomwe imatha kutuluka m'mapaipi akale ndi chosungunula mapaipi. ; mercury; Viable Cryptosporidium ndi Giardia, tizilombo toyambitsa matenda awiri omwe angakhalepo; Chloramine ndi mankhwala ophera tizilombo a chlorine-ammonia omwe amagwiritsidwa ntchito kwambiri m'mafakitale osefera kum'mwera kwa United States. Chlorine yoyera imawola mwachangu m'madzi ofunda. AQ-5200 yavomerezedwanso motsutsana ndi "zodetsa" 15 zomwe zikuwonekera kwambiri m'madzi, kuphatikiza BPA, ibuprofen ndi estrone (estrogen yomwe imagwiritsidwa ntchito poletsa kubereka), microplastics, komanso PFOA ndi PFOS, mankhwala ochokera ku fluoride yamakampani. amapezeka kwambiri m'madzi apampopi aku US. Ilinso ndi chitsimikizo cha VOC. Izi zikutanthauza kuti imatha kuchotsa bwino mankhwala opitilira 50 achilengedwe, kuphatikiza mankhwala ambiri ophera tizilombo ndi zinthu zina zoyambira mafakitale.
Kuwonjezera pa utomoni wosinthidwa wa kaboni ndi ayoni (zomwe zimagwiritsidwa ntchito mu zosefera zambiri, ngati si zonse, pansi pa sinki), Aquasana imagwiritsa ntchito ukadaulo wina wowonjezera wosefera kuti ipeze satifiketi. Pa ma chloramine, kaboni woyambitsa umawonjezedwa, kutanthauza, kaboni woyambitsa, womwe ndi woboola ndipo motero umagwira ntchito bwino, wopangidwa pochiza kaboni ndi mpweya wotentha kwambiri. Pa cryptosporidium ndi giardia, Aquasana imapanga zosefera zokhala ndi ma pore size ochepera 0.5 microns, zomwe ndi zazing'ono mokwanira kuzigwira.
Chitsimikizo cha fyuluta ya Aquasana AQ-5200 chinali chifukwa chachikulu chomwe tinasankhira. Koma kapangidwe kake ndi zipangizo zake zimasiyanitsanso ndi zina. Faucet imapangidwa ndi chitsulo cholimba, monga momwe zilili ndi T-piece yomwe imalumikiza fyuluta ku chitoliro. Opikisana ena amagwiritsa ntchito pulasitiki pa chimodzi kapena zonse ziwiri, zomwe zimachepetsa ndalama koma zimawonjezera chiopsezo cha mabatani odumphadumpha ndi kuyika kosayenera. AQ-5200 imagwiritsa ntchito zolumikizira zokakamiza kuti ipange chisindikizo cholimba komanso chotetezeka pakati pa chitoliro ndi chubu cha pulasitiki chomwe chimanyamula madzi kupita ku fyuluta ndi chitoliro. Opikisana ena amagwiritsa ntchito zolumikizira zosavuta, zomwe sizodalirika kwenikweni. Faucet ya AQ-5200 imapezeka m'mitundu itatu (nickel yopukutidwa, chrome yopukutidwa ndi bronze yopukutidwa ndi mafuta), pomwe opikisana ena sakukupatsani mwayi wosankha.
Timakondanso kapangidwe kake ka AQ-5200. Imagwiritsa ntchito ma fyuluta awiri, iliyonse yayikulu pang'ono kuposa chidebe cha soda; ma fyuluta ena, kuphatikiza Aquasana AQ-5300+ pansipa, amapangidwira mabotolo a lita. Ndi fyuluta yoyikidwa pa bulaketi yoyikira, AQ-5200 imakhala ndi mainchesi 9 kutalika, mainchesi 8 m'lifupi, ndi mainchesi 4 kuya; Aquasana AQ-5300+ imakhala ndi mainchesi 13 x 12 x 4. Izi zikutanthauza kuti AQ-5200 imatenga malo ochepa kwambiri pansi pa kabati, zomwe zimapangitsa kuti iikidwe m'malo opapatiza pomwe makina akuluakulu sangaikidwe, zomwe zimapangitsa kuti malo osungira pansi pa kabati akhale ambiri. Mudzafunika malo okwana mainchesi 11 (oyezedwa kuchokera pamwamba pa kabati kupita pansi) kuti musinthe fyuluta ndi mainchesi pafupifupi 9 ozungulira m'makoma a kabati kuti muyike kabati.
AQ-5200 yalandira ndemanga zabwino kwambiri monga fyuluta yamadzi, yapeza nyenyezi 4.5 mwa ndemanga 5 mwa ndemanga zoposa 800 patsamba la Aquasana ndi nyenyezi 4.5 mwa ndemanga pafupifupi 500 ku Home Depot.
Pomaliza, pamtengo wamakono wa pafupifupi $140 pa makina onse (nthawi zambiri mtengo wake ndi pafupifupi $100) ndi $60 pa seti ya zosefera zosinthira ($120 pachaka ndi nthawi yosinthira ya miyezi isanu ndi umodzi), Aquasana AQ-5200 ndi yomwe tikufuna. Imodzi mwa mapangano abwino kwambiri pakati pa omwe akupikisana nawo komanso yotsika mtengo kwambiri kuposa mitundu ina yokhala ndi ziphaso zochepa. Chipangizochi chili ndi nthawi yomwe imalira mukafuna kusintha zosefera, koma tikukulimbikitsani kuti muyikenso zikumbutso za kalendala pafoni yanu nthawi zonse. (Simungathe kuphonya izi.)
Poyerekeza ndi ena omwe akupikisana nawo, Aquasana AQ-5200 ili ndi chiwongola dzanja chochepa kwambiri (0.5 gpm vs. 0.72 kapena kuposerapo) komanso mphamvu yochepa (magaloni 500 vs. magaloni 750 kapena kuposerapo). Izi ndi zotsatira zachindunji za kukula kwa fyuluta yaying'ono. Ponseponse, tikuganiza kuti zofooka zazing'onozi zimaposa kukula kwake kochepa. Ngati mukudziwa kuti mukufuna kuyenda bwino komanso magwiridwe antchito apamwamba, Aquasana AQ-5300+ ili ndi chiwongola dzanja cha 0.72 GPM ndi magaloni 800 koma ili ndi ndondomeko yofanana yosinthira fyuluta ya miyezi isanu ndi umodzi, pomwe Aquasana Claryum Direct Connect ili ndi chiwongola dzanja chofika magaloni 1.5 pamphindi. , chiwongola dzanja chodziwika bwino ndi magaloni 1.5 pamphindi. mpaka magaloni 784 ndi miyezi isanu ndi umodzi.
Malangizo ogwiritsira ntchito makina a AQ-5200 ndi ochepa pang'ono ndipo zigawo zina sizikuwonetsedwa pamndandanda wa zigawo kapena pazithunzi. Izi sizidzavutitsa eni ake ambiri. Kwenikweni, chomwe muyenera kuchita ndikulumikiza mapaipi angapo ku madzi ndi mipopi, ndipo chilichonse chidzadzifotokozera chokha. (Kupatulapo ndi makina ochapira okongoletsera achitsulo chosapanga dzimbiri, omwe sanatchulidwe; amayikidwa poyamba pa pompo, kenako ndi makina ochapira a rabara owonda.) Kunena zoona, kuchokera pa zomwe tidawona mu kafukufuku wathu. Koma tikukhulupirira kuti malangizowa adzasinthidwa mtsogolomu. Pakadali pano, nayi kanema kuchokera ku Aquasana wokhudza momwe mungayikitsire AQ-5200.
Monga tafotokozera pamwambapa mu gawo la How We Choose, zosefera zamadzi zomwe zili pansi pa sinki (kuphatikizapo AQ-5200) nthawi zina zimalephera kwambiri, zomwe zimapangitsa kuti madzi awonongeke kwambiri ngati vutoli silinazindikirike ndikukonzedwa mwachangu. Samalani kwambiri mukakhazikitsa zolumikizira zolumikizirana osati zolumikizirana ndikuwonetsetsa kuti ma payipi ali otetezeka kenako pang'onopang'ono muyatsenso madzi kuti mupeze ndikukonza kutayikira kusanachitike ngozi. Zipangizo zozindikira kutayikira kwanzeru zimatha kuzindikira kutayikira koopsa, mosasamala kanthu za chifukwa chake, zisanawononge kwambiri.
Monga mitundu yathu yonse, Aquasana AQ-5200 imabwera ndi faucet yakeyake, yomwe singagwirizane ndi kalembedwe kanu. Muthanso kukhazikitsa faucet ina yomwe mungasankhe bola ngati kukula kwa faucet ndi mainchesi ⅜. Koma muyenera kuyerekeza kuchuluka kwa madzi ake ndi 0.5 GPM ya Aquasana chifukwa chitsimikizo cha fyuluta chimadalira kuchuluka kwa madzi. Dziwani kuti, kugwiritsa ntchito faucet yanu kumatanthauza kuti makina anu salinso ndi satifiketi ya ANSI/NSF.
Ngati mukukayikira kuti madzi anu ali ndi matope (mtundu wa lalanje womwe umabwera chifukwa cha dzimbiri ndi chizindikiro; komanso zomwe mudakumana nazo kale ndi fyuluta iliyonse, kuphatikizapo miphika, yomwe imatsekeka isanathe nthawi yomwe imayembekezeredwa), mungafune kuyang'ana mafyuluta ena ofanana nawo. Aquasana AQ-5300 yokhala ndi fyuluta yowonjezera ya matope.
Pogulitsidwa ngati fyuluta yamadzi oyera ya carbon block iwiri (yokonzekera kulumidwa) ya makina osefera madzi omwe ali pansi pa sinki, AO Smith AO-US-200 ndi yofanana ndi Aquasana AQ-5200 yapamwamba kwambiri m'njira zonse zofunika. Ili ndi ziphaso zofanana za ANS/NSF (PDF), kukula kofanana, ukadaulo wosefera, kapangidwe ka zitsulo zonse, zomangira zokakamiza, kuchuluka kwa madzi oyenda a 0.5 GPM, ndi mphamvu ya magaloni 500. Nthawi zambiri imabwera ndi zosefera zina pamtengo womwewo. Palibe chovuta pa izi: AO Smith idagula Aquasana mu 2016 ndipo, wolankhulira AO Smith adatiuza, "ikugwiritsa ntchito" ukadaulo wa Aquasana ndipo ilibe mapulani ochotsa mtundu wa Aquasana.
