Wirecutter imathandizira owerenga. Mukagula kudzera pa ulalo womwe uli patsamba lathu, tikhoza kulandira komishoni yogwirizana. Dziwani zambiri
Tinapanganso Aquasana Claryum Direct Connect chisankho chabwino - ndi yosavuta kuyiyika ndipo imatha kupereka madzi ambiri ku mipope yomwe ilipo.
Aliyense amene amamwa madzi ochulukirapo magaloni ochepa patsiku angakonde kugwiritsa ntchito njira yosefera madzi yomwe ili pansi pa thanki monga Aquasana AQ-5200. Ngati mukufuna (kapena mukufuna) madzi osefedwa, awa akhoza kuperekedwa nthawi zonse kuchokera ku pompo lina ngati pakufunika. Tikukulimbikitsani kuti mugwiritse ntchito Aquasana AQ-5200 chifukwa satifiketi yake ndiyo yabwino kwambiri kuposa njira zonse zomwe tapeza.
Aquasana AQ-5200 yapeza satifiketi yowononga kwambiri, ikupezeka paliponse, ndi yotsika mtengo, ndipo ili ndi kapangidwe kakang'ono. Ndi njira yoyamba yosefera madzi yomwe tikufuna.
Aquasana AQ-5200 yapambana satifiketi ya ANSI/NSF ndipo imatha kuchotsa zinthu zoipitsa pafupifupi 77, kuphatikizapo lead, mercury, mankhwala osungunuka achilengedwe, mankhwala osokoneza bongo, ndi zinthu zina zomwe sizimagwidwa kawirikawiri ndi opikisana nawo. Ndi imodzi mwa zosefera zochepa kwambiri zomwe zavomerezedwa kuti zigwiritsidwe ntchito pakupanga zinthu zosamatira ndipo idalandira upangiri wa zaumoyo wa EPA mu February 2019.
Mtengo wosintha zosefera ndi pafupifupi US$60, kapena nthawi yosinthira ya miyezi isanu ndi umodzi yomwe Aquasana adalimbikitsa ndi US$120 pachaka. Kuphatikiza apo, makinawa ndi akulu kuposa zitini zochepa za soda ndipo satenga malo ambiri ofunika pansi pa sinki. Makinawa omwe amagwiritsidwa ntchito kwambiri amagwiritsa ntchito zipangizo zachitsulo zapamwamba, ndipo matepi ake amabwera ndi mitundu yosiyanasiyana.
AO Smith AO-US-200 ndi yofanana ndi Aquasana AQ-5200 pankhani ya satifiketi, zofunikira, ndi miyeso. Ndi yapadera kwa Lowe's ndipo chifukwa chake siipezeka kwambiri.
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 satifiketi yabwino kwambiri, zida zachitsulo zonse, komanso mawonekedwe ang'onoang'ono, koma chifukwa imagulitsidwa ku Lowe's kokha, kuchuluka kwake sikuli kwakukulu, ndipo faucet yake ndi imodzi yokha: nickel yopukutidwa. Ngati izi zikugwirizana ndi kalembedwe kanu, tikukulimbikitsani kugula pakati pa mitundu iwiriyi pamtengo: imodzi kapena inzake nthawi zambiri imakhala yotsika mtengo. Ndalama zosinthira zosefera ndizofanana: pafupifupi $60 pa seti, kapena $120 pachaka pa miyezi isanu ndi umodzi yomwe AO Smith akulimbikitsa.
AQ-5300+ ili ndi satifiketi yabwino kwambiri, koma chifukwa cha kuchuluka kwa madzi ndi mphamvu zosefera, ndi yoyenera mabanja omwe amagwiritsa ntchito madzi ambiri, koma mtengo wake ndi wokwera ndipo imatenga malo ambiri pansi pa sinki.
Madzi othamanga kwambiri a Aquasana AQ-5300+ ali ndi ziphaso 77 zofanana ndi zinthu zina zomwe timakonda, koma amapereka madzi othamanga kwambiri (magaloni 0.72 ndi 0.5 pamphindi) komanso mphamvu ya fyuluta (magaloni 800 ndi 500). Izi zimapangitsa kuti ikhale chisankho choyamba kwa mabanja omwe amafunikira madzi ambiri osefedwa ndipo akufuna kugwiritsa ntchito mwachangu. Imawonjezeranso fyuluta yoyambira kusefedwa, yomwe siipezeka mu AQ-5200; izi zitha kuwonjezera kuchuluka kwa madzi othamanga a fyuluta yoyipitsa m'mabanja omwe ali ndi madzi oundana. Mwanjira ina, chitsanzo cha AQ-5300+ (chokhala ndi fyuluta ya botolo la malita atatu) ndi chachikulu kwambiri kuposa AQ-5200 ndi AO Smith AO-US-200, koma nthawi yogwiritsira ntchito fyuluta ndi yofanana, miyezi isanu ndi umodzi. Ndipo mtengo wake woyambira ndi mtengo wosinthira fyuluta ndi wokwera (pafupifupi madola 80 aku US pa seti imodzi kapena madola 160 aku US pachaka). Chifukwa chake, yesani ubwino wake ndi ndalama zake zokwera.
Claryum Direct Connect ikhoza kuyikidwa popanda kuboola ndipo imapereka madzi osefedwa okwana malita 1.5 pamphindi kudzera mu pompo yanu yomwe ilipo.
Claryum Direct Connect ya Aquasana imalumikizana mwachindunji ndi pompopompo yanu yomwe ilipo, zomwe zimapangitsa kuti ikhale njira yokongola kwambiri kwa obwereka (angaletsedwe kusintha malo awo) ndi iwo omwe sangathe kuyika pompopompo yosiyana. Siyeneranso kuyikidwa pakhoma la kabati ya sinki - imangoyikidwa pambali pake. Imapereka ziphaso zofanana za ANSI/NSF 77 monga njira zina za Aquasana ndi AO Smith, ndipo imatha kupereka magaloni 1.5 a madzi osefedwa pamphindi, kuposa zinthu zina. Mphamvu yovomerezeka ya fyuluta ndi magaloni 784, kapena pafupifupi miyezi isanu ndi umodzi yogwiritsidwa ntchito. Koma ilibe sediment pre-filter, kotero ngati muli ndi vuto la sediment, si chisankho chabwino chifukwa idzatsekeka. Ndipo ndi yayikulu kwambiri—mainchesi 20½ x 4½—kotero ngati kabati yanu ya sinki ndi yaying'ono kapena yodzaza, singakhale yoyenera.
Aquasana AQ-5200 yapeza satifiketi yowononga kwambiri, ikupezeka paliponse, ndi yotsika mtengo, ndipo ili ndi kapangidwe kakang'ono. Ndi njira yoyamba yosefera madzi yomwe tikufuna.

Ndakhala ndikuyesa zosefera zamadzi za Wirecutter kuyambira mu 2016. Mu lipoti langa, ndidakambirana mwatsatanetsatane ndi bungwe lopereka chitsimikizo cha zosefera kuti ndimvetse momwe mayeso awo adachitikira, ndipo ndidafufuza mu database yawo ya anthu onse kuti nditsimikizire kuti zomwe wopanga adalemba zidathandizidwa poyesa ziphaso. Ndalankhulanso ndi oimira opanga zosefera zamadzi angapo, kuphatikiza Aquasana/AO Smith, Filtrete, Brita, ndi Pur, kuti ndiwafunse zomwe adanena. Ndipo ndakumana ndi zosankha zathu zonse, chifukwa kukhala ndi moyo wabwino, kulimba komanso kugwiritsa ntchito mosavuta ndikofunikira kwambiri pazida zomwe mumagwiritsa ntchito kangapo patsiku. Wasayansi wakale wa NOAA John Holecek adafufuza ndikulemba buku loyambirira la zosefera zamadzi la Wirecutter, adachita mayeso ake, adalamula mayeso ena odziyimira pawokha, ndipo adandiphunzitsa zambiri zomwe ndikudziwa. Ntchito yanga yamangidwa pamaziko ake.
Mwatsoka, palibe yankho lofanana la ngati fyuluta yamadzi ikufunika. Ku United States, madzi a anthu onse amayendetsedwa ndi EPA motsatira 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. Mofananamo, zinthu zodetsa zimatha kulowa m'madzi mutatuluka m'malo oyeretsera mwa kulowa kapena kutuluka m'mapaipi otuluka (PDF). Kuyeretsa madzi kochitidwa (kapena kunyalanyazidwa) kufakitale kungapangitse kuti madzi atuluke m'mapaipi otsika—monga momwe zinachitikira ku Flint, Michigan.
Kuti mumvetse bwino zosakaniza zomwe zili m'madzi pamene wogulitsa akuchoka ku fakitale, nthawi zambiri mumatha kupeza lipoti la chidaliro cha ogula la EPA la wogulitsa wakomweko pa intaneti; ngati sichoncho, ogulitsa madzi onse apagulu ayenera kukupatsani CCR yawo malinga ndi zomwe mukufuna. Komabe, chifukwa cha kuipitsidwa komwe kungachitike pambuyo pake, njira yokhayo yodziwira kapangidwe ka madzi anu ndikufunsa labotale yamtundu wa madzi yakomweko kuti ikayesedwe.
Kutengera ndi zomwe zachitika: nyumba yanu kapena dera lanu likakula, chiopsezo cha kuipitsidwa kwa madzi m'madzi chimakhala chachikulu. Bungwe la US Environmental Protection Agency linati "nyumba zomwe zinamangidwa isanafike 1986 zimakhala ndi mwayi wogwiritsa ntchito mapaipi a lead, zida zomangira, ndi solder" - zomwe kale zinali zinthu zakale zomwe sizinakwaniritse zofunikira zamakono. Ukalamba umawonjezeranso mwayi woti madzi apansi panthaka aipitsidwe ndi makampani akale olamulira, zomwe zingakhale zoopsa, makamaka zikaphatikizidwa ndi kuwonongeka komwe kumakhudzana ndi mapaipi apansi panthaka okalamba.
Ngati banja lanu limamwa madzi opitilira malita awiri kapena atatu patsiku, ndiye kuti fyuluta yosungira madzi pansi pa sinki ingakhale yabwino kuposa fyuluta yosungira madzi pansi pa sinki. Dongosolo lomwe lili pansi pa sinki limapereka madzi osefedwa nthawi iliyonse akafuna, osadikira kuti njira yosefedwa ithe, monga momwe thanki yamadzi imasefedwa. Kusefedwa kwa madzi "pakufunika" kumatanthauzanso kuti dongosolo losungira madzi pansi pa sinki lingapereke madzi okwanira ophikira - mwachitsanzo, mutha kudzaza mphika ndi madzi osefedwa kuti muphike pasitala, koma simudzadzazanso mphikawo mobwerezabwereza chifukwa cha izi.
Poyerekeza ndi zosefera za sinki, zosefera za pansi pa sinki zimakhala ndi mphamvu yayikulu komanso nthawi yayitali yogwira ntchito - nthawi zambiri magaloni mazana ambiri ndi miyezi isanu ndi umodzi kapena kuposerapo, pomwe zosefera zambiri za sinki zimakhala magaloni 40 ndi miyezi iwiri. Chifukwa zosefera za pansi pa sinki zimagwiritsa ntchito mphamvu ya madzi m'malo mwa mphamvu yokoka kuti zikankhire madzi mu sefa, zosefera zawo zimatha kukhala zokhuthala, kotero zimatha kuchotsa zinthu zambiri zodetsa.
Vuto lake ndilakuti ndi okwera mtengo kuposa zosefera za pitcher, ndipo mtengo wake weniweni komanso nthawi yapakati yosinthira zosefera nazonso ndi zokwera mtengo. Dongosololi limatenganso malo mu kabati la sinki lomwe lingagwiritsidwe ntchito kusungiramo zinthu.
Kuyika fyuluta pansi pa sinki kumafuna kukhazikitsa mapaipi ndi zida zoyambira, koma ntchitoyi ndi yosavuta pokhapokha ngati sinki yanu ili kale ndi bowo lapamadzi losiyana. Ngati sichoncho, muyenera kuchotsa malo a pompo yomangidwa mkati (mutha kuwona diski yokwezedwa pa sinki yachitsulo, kapena chizindikiro pa sinki yopangidwa ndi miyala). Ngati dzenje logunda silikupezeka, muyenera kuboola dzenje mu sinki. Ngati sinki yanu yayikidwa pansi, muyeneranso kuboola dzenje pa kauntala. Ngati pakadali pano muli ndi chotsukira sopo, mpata wa mpweya mu chotsukira mbale, kapena chopopera chogwira ndi manja pa sinki, mutha kuchichotsa ndikuchiyika pamenepo.
Pambuyo poyesa, tasintha fyuluta ya Pur Pitcher yomwe sinagwiritsidwe ntchito ndi fyuluta ya Faster Pour Pitcher.
Bukuli likunena za mtundu winawake wa fyuluta yosungira madzi pansi pa sinki: yomwe imagwiritsa ntchito fyuluta ya cartridge ndikutumiza madzi osefedwa ku pompo lina. Izi ndi fyuluta zodziwika kwambiri zosungira madzi pansi pa sinki. Zimatenga malo ochepa kwambiri ndipo nthawi zambiri zimakhala zosavuta kuyika ndi kusamalira. Zimagwiritsa ntchito zinthu zokoka madzi—nthawi zambiri ma resini osinthika a kaboni ndi ayoni, monga ma fyuluta a thanki yamadzi—kuti zimange ndikuchotsa zodetsa. Sitikulankhula za ma fyuluta, makina osinthira osmosis, kapena ma pitcher kapena zotulutsira madzi zina zomwe zimayikidwa pa ma tapi.
Kuti tiwonetsetse kuti tikulimbikitsa zosefera zodalirika zokha, nthawi zonse takhala tikunena kuti zomwe tasankha zadutsa satifiketi yokhazikika yamakampani: ANSI/NSF. American National Standards Institute ndi NSF International ndi mabungwe osachita phindu omwe amagwira ntchito ndi EPA, oimira mafakitale, ndi akatswiri ena kuti akhazikitse miyezo yokhwima yaubwino ndi njira zoyesera zinthu zambirimbiri, kuphatikizapo zosefera zamadzi. Ma laboratories awiri akuluakulu otsimikizira za oyeretsa madzi ndi NSF International yokha ndi Water Quality Association (WQA). Onse awiri ali ovomerezeka mokwanira ndi ANSI ndi Canadian Standards Council ku North America, amatha kuyesedwa ngati ali ndi satifiketi ya ANSI/NSF, ndipo onse ayenera kutsatira miyezo yoyesera ndi njira zomwezo. Sefayi imatha kukwaniritsa miyezo yokhazikika ya satifiketi ikapitirira nthawi yomwe imayembekezeredwa. Gwiritsani ntchito zitsanzo "zovuta" zokonzedwa, zomwe zimakhala zodetsedwa kwambiri kuposa madzi ambiri apampopi.
Mu bukhuli, tikuyang'ana kwambiri pa zosefera zomwe zili ndi chlorine, lead, ndi VOC (yomwe imadziwikanso kuti volatile organic compound).
Chitsimikizo cha chlorine (pansi pa ANSI/Standard 42) n'chofunika chifukwa chlorine nthawi zambiri ndiye amachititsa madzi apampopi "osakoma bwino". Koma ichi ndi chinyengo: pafupifupi mitundu yonse ya zosefera madzi yadutsa chitsimikizo chake.
Chitsimikizo cha lead ndi chovuta kupeza chifukwa chimatanthauza 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 a biocides ndi zinthu zina zoyambira mafakitale. Si zosefera zonse zomwe zili pansi pa sinki zomwe zili ndi zitsimikizo ziwirizi, kotero poyang'ana kwambiri zosefera zomwe zili ndi zitsimikizo ziwiri, tazindikira zomwe zili ndi magwiridwe antchito apamwamba kwambiri.
Tinachepetsa kusaka kwathu ndipo tinasankha zosefera zomwe zinavomerezedwanso pansi pa ANSI/NSF Standard 401 yatsopano, yomwe imakhudza zinthu zodetsa zomwe zikubwera, monga mankhwala, zomwe zimapezeka kwambiri m'madzi aku America. Mofananamo, si zosefera zonse zomwe zili ndi satifiketi ya 401, kotero zosefera zomwe zili nazo (ndi satifiketi ya lead ndi VOC) ndi gulu losankha kwambiri.
Mu gawo lokhwima ili, timayang'ana omwe ali ndi mphamvu zosachepera magaloni 500. Izi zikufanana ndi nthawi ya fyuluta ya miyezi pafupifupi 6 yomwe imagwiritsidwa ntchito kwambiri (magaloni 2¾ patsiku). Kwa mabanja ambiri, izi ndizokwanira kukwaniritsa zosowa za tsiku ndi tsiku za kumwa ndi kuphika. (Wopanga amapereka ndondomeko yosinthira fyuluta, nthawi zambiri m'miyezi osati m'magaloni; timatsatira malangizo awa mukuwunika kwathu ndi kuwerengera mtengo. Timalimbikitsa nthawi zonse kugwiritsa ntchito chosinthira cha wopanga woyambirira m'malo mwa fyuluta ya chipani chachitatu.)
Pomaliza, tinayesa mtengo woyambira wa makina onse komanso mtengo wopitilira wosinthira fyuluta. Sitinakhazikitse mtengo wotsika kapena wapamwamba, koma kafukufuku wathu akuwonetsa kuti ngakhale mtengo woyambira umayambira pa US$100 mpaka US$1,250, ndipo mtengo woyambira fyuluta umayambira pa US$60 mpaka pafupifupi US$300, kusiyana kumeneku sikuli kwakukulu kwambiri. Mtundu wokwera mtengo kwambiri m'mafotokozedwe. Tapeza mitundu ingapo ya fyuluta yotsika mtengo yomwe imadula pansi pa US$200, pomwe imapereka satifiketi yabwino komanso moyo wautali. Awa adakhala omaliza athu. Kuphatikiza apo, tikuyang'ananso:
Pa kafukufukuyu, nthawi zina tinkakumana ndi malipoti oopsa okhudza kutayikira kwa madzi kuchokera kwa mwiniwake wa fyuluta yamadzi pansi pa sinki. Popeza fyulutayo imalumikizidwa ndi chitoliro cholowera madzi ozizira kudzera mu chitoliro, ngati cholumikizira kapena payipi yasweka, madziwo amatuluka mpaka valavu yotseka itatsekedwa - zomwe zikutanthauza kuti zingatenge maola kapena masiku kuti mupeze vutoli, zomwe zingakubweretsereni mavuto aakulu. Kuwonongeka kwa madzi. Izi sizachilendo, koma muyenera kuyeza zoopsa mukaganizira zogula fyuluta pansi pa sinki. Ngati mugula, chonde tsatirani malangizo oyika mosamala, samalani kuti musadutse ulusi wolumikizira, kenako pang'onopang'ono muyatse madzi kuti muwone ngati akutayikira.
Fyuluta ya reverse osmosis kapena R/O poyamba inkagwiritsa ntchito mtundu womwewo wa fyuluta ya cartridge monga momwe tinasankhira pano, koma inawonjezera njira yachiwiri yosefera reverse osmosis: nembanemba yokhala ndi mabowo abwino yomwe imalola madzi kudutsa koma imasefa mchere wosungunuka. Zinthu ndi zinthu zina.
Tikhoza kukambirana mozama za zosefera za R/O m'mabukhu amtsogolo. Pano, tinazikana kwathunthu. Poyerekeza ndi zosefera zokometsera madzi, zimapereka ubwino wochepa; zimapanga madzi ambiri otayika (nthawi zambiri magaloni 4 a madzi otayika "otsukidwa" pa galoni iliyonse ya zosefera), pomwe zosefera zokometsera madzi sizitenga malo. Ndi zazikulu kwambiri chifukwa, mosiyana ndi zosefera zokometsera madzi, zimagwiritsa ntchito matanki a galoni imodzi kapena magaloni awiri kusungira madzi osefedwa; ndi zochedwa kwambiri kuposa zosefera zokometsera madzi pansi pa sinki.
M'zaka zingapo zapitazi, takhala tikuchita mayeso a labotale pa zosefera zamadzi. Chomaliza chomwe tapeza kuchokera ku mayesowa ndichakuti satifiketi ya ANSI/NSF ndi muyeso wodalirika wa magwiridwe antchito a zosefera. Popeza mayeso a satifiketi ndi ovuta kwambiri, izi sizodabwitsa. Kuyambira pamenepo, tadalira satifiketi ya ANSI/NSF m'malo mwa mayeso athu ochepa kuti tisankhe opikisana nawo.
Mu 2018, tinayesa njira yotchuka yosefera madzi ya Big Berkey, yomwe sinatsimikizidwe ndi ANSI/NSF, koma inati yayesedwa kwambiri mogwirizana ndi miyezo ya ANSI/NSF. Izi zinalimbitsanso kukakamira kwathu pa satifiketi yeniyeni ya ANSI/NSF komanso kusakhulupirira kwathu mawu akuti "ANSI/NSF yoyesedwa".
Kuyambira nthawi imeneyo, kuphatikizapo 2019, mayeso athu akhala akuyang'ana kwambiri momwe zinthu zingagwiritsidwire ntchito komanso zinthu zosiyanasiyana zothandiza komanso zofooka zomwe zidzaonekera mukagwiritsa ntchito zinthuzi.
Aquasana AQ-5200 yapeza satifiketi yowononga kwambiri, ikupezeka paliponse, ndi yotsika mtengo, ndipo ili ndi kapangidwe kakang'ono. Ndi njira yoyamba yosefera madzi yomwe tikufuna.
Tinasankha Aquasana AQ-5200, yomwe imadziwikanso kuti Aquasana Claryum Dual-Stage. Pakadali pano, chinthu chofunika kwambiri ndichakuti fyuluta yake yapeza satifiketi yabwino kwambiri ya ANSI/NSF pakati pa opikisana nawo, kuphatikizapo chlorine, chloramine, lead, mercury, VOC, mitundu yosiyanasiyana ya "zonyansa zomwe zikubwera", ndi perfluorooctanoic acid ndi Perfluorooctane sulfonic acid. Kuphatikiza apo, zida zake za faucet ndi plumbing zimapangidwa ndi chitsulo cholimba, chomwe chili bwino kuposa mapulasitiki omwe amagwiritsidwa ntchito ndi opanga ena. Ndipo dongosololi ndi laling'ono kwambiri. Pomaliza, Aquasana AQ-5200 ndi imodzi mwa zinthu zamtengo wapatali kwambiri zomwe tidapeza mu fyuluta pansi pa sinki. Mtengo wolipiriratu wa dongosolo lonse (fyuluta, nyumba, faucet ndi zida) nthawi zambiri ndi US$140, ndipo ziwiri ndi US$60. Sinthani fyuluta. Izi ndizochepa kuposa opikisana nawo ambiri omwe ali ndi ziphaso zofooka.
Aquasana AQ-5200 yapambana satifiketi ya ANSI/NSF (PDF) ndipo imatha kuthana ndi zodetsa 77. Pamodzi ndi Aquasana AQ-5300+ yovomerezeka yomweyi ndi AO Smith AO-US-200, izi zimapangitsa AQ-5200 kukhala njira yamphamvu kwambiri yotsimikizira yomwe tidasankha. (AO Smith adagula Aquasana mu 2016 ndipo adagwiritsa ntchito ukadaulo wake wambiri; AO Smith alibe mapulani othetsa mndandanda wa Aquasana.) Mosiyana ndi zimenezi, Pur Pitcher Filter yabwino kwambiri yokhala ndi Lead Reduction ili ndi satifiketi ya 23.
Ziphasozi zikuphatikizapo chlorine, yomwe imagwiritsidwa ntchito kupha tizilombo toyambitsa matenda m'madzi a m'matauni ndipo ndiyo chifukwa chachikulu cha "kununkhiza" madzi a m'mpopi; lead, yomwe imatha kutuluka m'mapaipi akale ndi chosungunula mapaipi; mercury; Cryptosporidium yamoyo ndi Giardia, Matenda awiri omwe angakhalepo; chloramine ndi mankhwala ophera tizilombo toyambitsa matenda a chloramine, omwe amagwiritsidwa ntchito kwambiri m'mafakitale osefera kum'mwera kwa United States, komwe chlorine yoyera imawonongeka mwachangu m'madzi ofunda. Aquasana AQ-5200 yapambananso chiphaso cha "zonyansa zotuluka" 15, zomwe zikuwonjezeka m'makina operekera madzi a anthu onse, kuphatikizapo bisphenol A, ibuprofen, ndi estrone (estrogen yogwiritsidwa ntchito poletsa kubereka); Pa mankhwala ochokera ku PFOA ndi PFOS-fluorine omwe amagwiritsidwa ntchito popanga zinthu zosamatira, ndipo adalandira upangiri wa zaumoyo wa EPA mu February 2019. (Panthawi yokambirana, opanga atatu okha a mtundu uwu wa fyuluta adapeza chiphaso cha PFOA/S, zomwe zimapangitsa izi kukhala zodziwika bwino.) Yapambananso chiphaso cha VOC. Izi zikutanthauza kuti imatha kuchotsa bwino mankhwala opitilira 50 osiyanasiyana achilengedwe, kuphatikizapo mankhwala ambiri ophera tizilombo ndi zinthu zina zoyambira mafakitale.
Kuwonjezera pa ma resini osinthika a kaboni ndi ma ion (ma filter ambiri, ngati si onse, omwe ali pansi pa thanki ndi ofala), Aquasana imagwiritsanso ntchito ukadaulo wina wowonjezera wosefera kuti ipeze satifiketi. Pa ma chloramine, imawonjezera kaboni wothandiza, womwe ndi mtundu wa kaboni wothandiza womwe umapangidwa pochiza kaboni ndi mpweya wotentha kwambiri. Pa Cryptosporidium ndi Giardia, Aquasana imapanga zosefera pochepetsa kukula kwa ma pore kufika pa 0.5 microns, zomwe zimakwanira kuzigwira.
Chitsimikizo chabwino kwambiri cha fyuluta ya Aquasana AQ-5200 ndicho chifukwa chachikulu chomwe tidasankhira. Koma kapangidwe kake ndi zipangizo zake zimapangitsanso kuti ikhale yapadera. Faucet imapangidwa ndi chitsulo cholimba, monga momwe zilili ndi chogwirira cha T chomwe chimalumikiza fyuluta ku chitoliro. Opikisana ena amagwiritsa ntchito pulasitiki pa chimodzi kapena ziwiri mwa izo, kuchepetsa ndalama, koma kumawonjezera chiopsezo cha ulusi wopingasa ndi zolakwika zoyika. AQ-5200 imagwiritsa ntchito zolumikizira zokakamiza kuti zitsimikizire kuti pali chisindikizo cholimba komanso chotetezeka pakati pa chitoliro chanu ndi chitoliro cha pulasitiki chomwe chimanyamula madzi kupita ku fyuluta ndi chitoliro; opikisana ena amagwiritsa ntchito zolumikizira zosavuta, zomwe sizili zotetezeka kwambiri. Faucet ya AQ-5200 imapezeka m'mitundu itatu (nickel yopukutidwa, chrome yopukutidwa ndi bronze wothira mafuta), ndipo opikisana ena alibe chochita.
Timakondanso kapangidwe kake ka AQ-5200. Imagwiritsa ntchito ma fyuluta awiri, omwe iliyonse ndi yayikulu pang'ono kuposa chidebe cha soda; ma fyuluta ena, kuphatikiza Aquasana AQ-5300+ pansipa, ndi kukula kwa botolo la lita imodzi.
