Ndakhala ndikuyesa zosefera zamadzi za Wirecutter kuyambira 2016. Mu lipoti langa, ndidakambirana mwatsatanetsatane ndi bungwe lotsimikizira zosefera kuti ndimvetsetse momwe kuyezetsa kwawo kunachitikira, ndikuwunikiranso munkhokwe yawo yapagulu kuti nditsimikizire kuti mawu a wopanga adathandizidwa pakuyesa certification. . Ndinalankhulanso ndi oimira angapo opanga zosefera madzi, kuphatikizapo Aquasana/AO Smith, Filtrete, Brita, ndi Pur, kuti ndiwafunse zomwe ananena. Ndipo ine ndekha ndakhala ndikukumana ndi zosankha zathu zonse, chifukwa kukhazikika, kulimba komanso kugwiritsa ntchito bwino ndizofunikira kwambiri pazida zomwe mumagwiritsa ntchito kangapo patsiku. Wasayansi wakale wa NOAA a John Holecek adafufuza ndikulemba kalozera wazosefera wamadzi wa Wirecutter, adayesa yekha, adapereka mayeso odziyimira pawokha, ndikundiphunzitsa zambiri zomwe ndikudziwa. Ntchito yanga yamangidwa pa maziko ake.
Tsoka ilo, palibe yankho lofanana ngati fyuluta yamadzi ikufunika. Ku United States, madzi opezeka pagulu amayendetsedwa ndi EPA molingana ndi lamulo la Water Water Act, ndipo malo opangira madzi otuluka pagulu ayenera kukwaniritsa miyezo yabwino kwambiri. Koma sizinthu zonse zoipitsa zomwe zimayendetsedwa ndi malamulo. Momwemonso, zowononga zimatha kulowa m'madzi zikachoka pamalo opangira mankhwalawo polowera kapena kutsika kuchokera ku mapaipi akutha (PDF). Kuthira madzi kochitidwa (kapena kunyalanyazidwa) ku fakitale kungapangitse kukhetsa madzi m'mapaipi otsika - monga zidachitikira ku Flint, Michigan.
Kuti mumvetse bwino zomwe zili m'madzi pamene wogulitsa akuchoka ku fakitale, nthawi zambiri mumatha kupeza lipoti lachikhulupiriro cha ogula la EPA ya ogulitsa m'deralo pa intaneti; ngati sichoncho, onse ogulitsa madzi a boma ayenera kukupatsani CCR yawo malinga ndi zomwe mukufuna. Komabe, chifukwa cha kuipitsidwa komwe kungachitike kumunsi kwa mtsinje, njira yokhayo yodziwira momwe madzi anu alili ndi kufunsa labotale yaubwino wa madzi kuti ayezedwe.
Kutengera ndi zomwe mwakumana nazo: nyumba yanu kapena dera lanu likamakalamba, chiwopsezo cha kuwonongeka kwa mitsinje chimakulirakulira. Bungwe loona za chitetezo cha zachilengedwe la ku United States linati “nyumba zomangidwa chaka cha 1986 chisanafike n’zosavuta kugwiritsa ntchito mapaipi opangidwa ndi mtovu, zinthu zina, ndi solder”—zimene kale zinali zinthu zakale zomwe sizinagwirizane ndi mmene zinthu zilili panopa. Zaka zimawonjezeranso mwayi wa kuipitsidwa kwa madzi apansi osiyidwa ndi makampani omwe kale anali olamulira, zomwe zingakhale zoopsa, makamaka zikaphatikizidwa ndi kuwonongeka kokhudzana ndi ukalamba wa mapaipi apansi panthaka.
Ngati banja lanu limamwa madzi akumwa opitilira malita awiri kapena atatu patsiku, ndiye kuti fyuluta ya pansi pa sinki ingakhale yabwino kuposa sefa ya thanki. Dongosolo lomwe lili pansi pa sinki limapereka madzi akumwa osefedwa pakufunika, osadikirira kumaliza kusefera, ngati thanki yamadzi. Kusefedwa kwa "pofuna" kumatanthauzanso kuti makina osungira pansi angapereke madzi okwanira kuphika-mwachitsanzo, mukhoza kudzaza mphika ndi madzi osefa kuti muphike pasitala, koma simudzadzaza mphika mobwerezabwereza chifukwa cha izi.
Poyerekeza ndi zosefera zakuya, pansi pa zosefera zakuya zimakhala ndi mphamvu zokulirapo komanso moyo wautali wautumiki-kawirikawiri magaloni mazana ndi miyezi isanu ndi umodzi kapena kuposerapo, pomwe zosefera zambiri zakuya ndi magaloni 40 Ndi miyezi iwiri. Chifukwa zosefera zapansi pa sinki zimagwiritsa ntchito kuthamanga kwa madzi m'malo mwa mphamvu yokoka kukankhira madzi kudzera mu fyuluta, zosefera zawo zimatha kukhala zolimba, kotero zimatha kuchotsa zowononga zambiri zomwe zingatheke.
Choyipa chake ndikuti ndi okwera mtengo kuposa zosefera za mbiya, ndipo mtengo wathunthu komanso nthawi yosinthira zosefera ndizokwera mtengo kwambiri. Dongosololi limatenganso malo mu kabati yakuya yomwe ingagwiritsidwe ntchito posungirako.
Kuyika fyuluta pansi pa sinki kumafuna mipope yoyambira ndi kuyika kwa hardware, koma ntchitoyi ndi yosavuta pokhapokha ngati sink yanu ili kale ndi dzenje lapadera. Ngati sichoncho, muyenera kugwetsa malo a faucet yomangidwa (mutha kuwona chimbale chokwera pazitsulo zachitsulo, kapena chizindikiro pamadzi opangira miyala). Ngati dzenje la percussion lilibe, muyenera kubowola mu sinki. Ngati sink yanu yaikidwa pansi, muyeneranso kubowola dzenje pa countertop. Ngati panopa muli ndi chotsutsira sopo, chotchingira mpweya mu chotsukira mbale, kapena chopopera pamanja pa sinki, mutha kuchichotsa ndikuchiyika pamenepo.
Titayesa, tasintha fyuluta yosiyidwa ya Pur Pitcher ndi fyuluta ya Fast Pour Pitcher.
Bukuli likunena za mtundu wina wa fyuluta ya pansi-sinki: omwe amagwiritsa ntchito fyuluta ya cartridge ndikutumiza madzi osefedwa pampopi wina. Izi ndi zosefera zodziwika bwino za pansi pa sinki. Amatenga malo ochepa kwambiri ndipo nthawi zambiri amakhala osavuta kukhazikitsa ndi kukonza. Amagwiritsa ntchito zinthu zopangira ma adsorbent - zomwe nthawi zambiri zimakhala zosinthidwa kaboni ndi ion, monga zosefera zamadzi - kuti amange ndi kuletsa zowononga. Sitikulankhula za zosefera, makina osinthira osmosis, kapena zotengera zina kapena zoperekera zomwe zimayikidwa pamapopi.
Kuwonetsetsa kuti timangopangira zosefera zodalirika, nthawi zonse takhala tikulimbikira kuti kusankha kwathu kwadutsa ziphaso zamakampani: ANSI/NSF. American National Standards Institute ndi NSF International ndi mabungwe osachita phindu omwe amagwira ntchito ndi EPA, oyimilira mafakitale, ndi akatswiri ena kuti akhazikitse miyezo yokhazikika komanso yoyeserera pazinthu zambiri, kuphatikiza zosefera zamadzi. Ma laboratories awiri otsimikizira oyeretsa madzi ndi NSF International palokha ndi Water Quality Association (WQA). Onsewa ndi ovomerezeka ndi ANSI ndi Canadian Standards Council ku North America, akhoza kuyesedwa kuti apeze certification ya ANSI/NSF, ndipo onse ayenera kutsatira miyezo ndi ma protocol omwewo. Fyulutayo imatha kukwaniritsa miyezo yotsimikizika ikadutsa kwambiri moyo wake womwe ukuyembekezeka. Gwiritsani ntchito zitsanzo "zovuta" zomwe zakonzedwa, zomwe zili zoipitsidwa kwambiri kuposa madzi ambiri apampopi.
Mu bukhuli, timayang'ana kwambiri zosefera zomwe zili ndi ma certification a chlorine, lead, ndi VOC (aka volatile organic compound).
Chitsimikizo cha klorini (pansi pa ANSI/Standard 42) n'chofunika chifukwa klorini nthawi zambiri ndi amene amachititsa kuti madzi a pampopi "ayipe". Koma ichi ndi pafupifupi gimmick: pafupifupi mitundu yonse ya zosefera madzi zadutsa chiphaso chake.
Chitsimikizo chotsogolera n'chovuta kukwaniritsa chifukwa chimatanthauza kuchepetsa mayankho olemera ndi 99%.
Chitsimikizo cha VOC chimakhalanso chovuta chifukwa zikutanthauza kuti fyulutayo imatha kuchotsa zinthu zopitilira 50, kuphatikiza ma biocides ambiri ndi zoyambira zamafakitale. Sikuti zosefera zonse zapansi panthaka zili ndi ziphaso ziwirizi, kotero poyang'ana kwambiri zosefera zomwe zili ndi ziphaso ziwiri, tazindikira omwe ali ndi magwiridwe antchito apamwamba kwambiri.
Tinachepetsa kusaka kwathu ndikusankha zosefera zomwe zidatsimikiziridwa pansi pa ANSI/NSF Standard 401 yatsopano, yomwe imakhudza zowononga zomwe zikubwera, monga mankhwala, zomwe zimapezeka kwambiri m'madzi aku America. Mofananamo, si zosefera zonse zomwe zili ndi certification 401, kotero zosefera zomwe zili nazo (ndi lead ndi VOC certification) ndi gulu losankha kwambiri.
Mugawo lokhwima ili, timayang'ana omwe ali ndi mphamvu zochepa zokwana magaloni 500. Izi ndizofanana ndi moyo wasefa pafupifupi miyezi isanu ndi umodzi yogwiritsidwa ntchito kwambiri (magalani 2¾ patsiku). Kwa mabanja ambiri, izi ndi zokwanira kukwaniritsa zosowa za tsiku ndi tsiku zakumwa ndi kuphika. (Opanga amapereka ndondomeko yovomerezeka yosinthira zosefera, nthawi zambiri m'miyezi osati magaloni; timatsatira malingalirowa pakuwunika kwathu ndi kuwerengera mtengo. Timalimbikitsa kugwiritsa ntchito chosinthira choyambirira m'malo mogwiritsa ntchito zosefera za gulu lina.)
Potsirizira pake, tinayesa mtengo wapatsogolo wa dongosolo lonse ndi mtengo wopitirizabe wochotsa fyulutayo. Sitinakhazikitse malire amtengo wotsika kapena apamwamba, koma kafukufuku wathu akuwonetsa kuti ngakhale mtengo wam'tsogolo umachokera ku US $ 100 mpaka US $ 1,250, ndipo mtengo wasefawu umachokera ku US $ 60 mpaka pafupifupi US $ 300, kusiyana kumeneku sikuposa kwambiri. Chitsanzo chokwera mtengo kwambiri muzofotokozera. Tapeza mitundu ingapo ya zosefera zapansi panthaka zomwe zimawononga ndalama zosachepera US$200, pomwe zimapereka ziphaso zabwino kwambiri komanso moyo wautali. Awa adakhala omaliza athu. Kuphatikiza apo, tikuyang'ananso:
Pakafukufukuyu, nthawi zina tidakumana ndi malipoti owopsa ochokera kwa eni ake a fyuluta yamadzi pansi pa sinkiyo. Popeza fyulutayo imalumikizidwa ndi chitoliro cholowetsa madzi ozizira kudzera mu chitoliro, ngati cholumikizira kapena payipi yathyoka, madzi amatuluka mpaka valavu yotseka itatsekedwa - zomwe zikutanthauza kuti zingatenge maola kapena masiku kuti muzindikire. vuto, amene adzakupatsani Bweretsani mavuto aakulu. Kuwonongeka kwamadzi. Izi sizachilendo, koma muyenera kuyeza kuopsa poganizira kugula fyuluta pansi lakuya. Mukagula, chonde tsatirani malangizo oyika mosamala, kusamala kuti musadutse ulusi wolumikizira, ndiyeno muyatse madzi pang'onopang'ono kuti muwone ngati akutuluka.
Reverse osmosis kapena R/O fyuluta poyambilira idagwiritsa ntchito fyuluta yamtundu womwewo wa cartridge monga tidasankha pano, koma idawonjezera njira yachiwiri yosefera ya osmosis: nembanemba yabwino kwambiri yomwe imalola kuti madzi adutse koma amasefa mchere wosungunuka. Zinthu ndi zinthu zina.
Titha kukambirana mozama zosefera za R/O m'mabuku amtsogolo. Apa, tidawakana kotheratu. Poyerekeza ndi zosefera za adsorption, zimapereka maubwino ochepera; amapanga madzi ambiri otayika (kawirikawiri magaloni 4 a madzi otayika "osungunuka" pa galoni ya kusefedwa), pamene zosefera za adsorption sizitero; amatenga malo Ndi aakulu kwambiri chifukwa, mosiyana ndi zosefera za adsorption, amagwiritsa ntchito 1 galoni kapena 2 galoni matanki kusunga madzi osefedwa; amachedwa kwambiri kuposa zosefera adsorption pansi pa sinki.
M'zaka zingapo zapitazi, tapanga mayeso a labotale pa zosefera zamadzi. Mfundo yaikulu yomwe tapeza kuchokera ku mayeserowa ndi yakuti certification ya ANSI/NSF ndi muyeso wodalirika wa kusefa. Poganizira kukhwima kwambiri pakuyesa certification, izi sizodabwitsa. Kuyambira pamenepo, takhala tikudalira certification ya ANSI/NSF m'malo mongoyesa tokha kuti tisankhe opikisana nawo.
Mu 2018, tidayesa makina osefera amadzi a Big Berkey otchuka, omwe sanatsimikizidwe ndi ANSI/NSF, koma akuti adayesedwa mozama motsatira miyezo ya ANSI/NSF. Zomwe zidachitikazi zidaphatikizanso kulimbikira kwathu pa satifiketi yowona ya ANSI/NSF komanso kusakhulupirira kwathu mawu a "ANSI/NSF tested".
Kuyambira nthawi imeneyo, kuphatikiza 2019, mayeso athu ayang'ana kwambiri momwe angagwiritsire ntchito zenizeni padziko lapansi komanso zinthu zosiyanasiyana zothandiza komanso zofooka zomwe zidzawonekere mukamagwiritsa ntchito zinthuzi.
Aquasana AQ-5200 yapeza chiphaso choyipitsidwa kwambiri, imapezeka ponseponse, ndiyotsika mtengo, ndipo ili ndi mawonekedwe ophatikizika. Ndi njira yoyamba yosefera madzi pansi pa thanki yomwe tikuyang'ana.
Tinasankha Aquasana AQ-5200, yomwe imadziwikanso kuti Aquasana Claryum Dual-Stage. Pakalipano, mbali yake yofunika kwambiri ndi yakuti fyuluta yake yapeza certification ya ANSI / NSF yabwino kwambiri pakati pa mpikisano wathu, kuphatikizapo chlorine, chloramine, lead, mercury, VOC, "zowononga" zosiyanasiyana zomwe zikutuluka, ndi perfluorooctanoic acid ndi Perfluorooctane sulfonic acid. Kuphatikiza apo, zida zake zopopera ndi mapaipi amapangidwa ndi chitsulo cholimba, chomwe ndi chabwino kuposa mapulasitiki omwe amagwiritsidwa ntchito ndi opanga ena. Ndipo dongosololi ndilophatikizana kwambiri. Pomaliza, Aquasana AQ-5200 ndi imodzi mwazinthu zamtengo wapatali zomwe tapeza mu fyuluta pansi pa sinki. Mtengo wolipiriratu wadongosolo lonse (sefa, nyumba, faucet ndi zida) nthawi zambiri ndi US $ 140, ndipo ziwiri ndi US $ 60. Bwezerani zosefera. Izi ndizochepera opikisana nawo ambiri omwe ali ndi ziphaso zofooka.
Aquasana AQ-5200 yadutsa chiphaso cha ANSI/NSF (PDF) ndipo imatha kuthana ndi zowononga 77. Pamodzi ndi certification ya Aquasana AQ-5300+ ndi AO Smith AO-US-200, izi zimapangitsa AQ-5200 kukhala dongosolo lamphamvu kwambiri la certification lomwe tingasankhe. (AO Smith adapeza Aquasana mu 2016 ndipo adagwiritsa ntchito teknoloji yake yambiri; AO Smith alibe ndondomeko yochotseratu mndandanda wa Aquasana.) Mosiyana ndi izi, Filter yabwino kwambiri ya Pur Pitcher yokhala ndi Lead Reduction imatsimikiziridwa pa 23.
Zitsimikizo izi zikuphatikizapo chlorine, yomwe imagwiritsidwa ntchito kupha tizilombo toyambitsa matenda m'madzi a tauni ndipo ndi chifukwa chachikulu cha "kununkhira" kwa madzi apampopi; kutsogolera, amene akhoza leached ku mipope akale ndi solder chitoliro; mercury; moyo Cryptosporidium ndi Giardia , Awiri angathe tizilombo toyambitsa matenda; chloramine ndi mankhwala ophera tizilombo toyambitsa matenda a chloramine, omwe amagwiritsidwa ntchito mochulukira muzosefera zakumwera kwa United States, komwe chlorine yoyera imawonongeka mwachangu m'madzi ofunda. Aquasana AQ-5200 yadutsanso chivomerezo cha 15 "zowononga zowonongeka", zomwe zikuwonjezeka mu machitidwe operekera madzi a anthu, kuphatikizapo bisphenol A, ibuprofen, ndi estrone (estrogen yomwe imagwiritsidwa ntchito poletsa mimba); Pazinthu za PFOA ndi PFOS-fluorine zomwe zimagwiritsidwa ntchito popanga zinthu zopanda ndodo, ndipo adalandira uphungu wa zaumoyo wa EPA mu February 2019. (Panthawi yokambirana, opanga atatu okha amtundu uwu wa fyuluta adalandira chiphaso cha PFOA/S, chomwe zimapangitsa izi kukhala zofunika kwambiri.) Yadutsanso satifiketi ya VOC. Izi zikutanthauza kuti imatha kuchotsa bwino zinthu zopitilira 50, kuphatikiza mankhwala ambiri ophera tizilombo ndi zoyambira zamafakitale.
Kuphatikiza pa activated carbon and ion exchange resins (zambiri, ngati si zonse, zosefera zapansi pa thanki ndizofala), Aquasana amagwiritsanso ntchito matekinoloje awiri owonjezera osefera kuti apeze ziphaso. Kwa ma chloramines, amawonjezera mpweya wa catalytic, womwe ndi mtundu waporous wa carbon activated wopangidwa pochiza mpweya ndi mpweya wotentha kwambiri.
