He nui te hunga e tautoko ana i ngā tātari wai o Big Berkey. Kua roa mātou e rangahau ana i ngā ipu tātari wai pai rawa atu me ngā tātari wai pai rawa atu i raro i te totohu, ā, he maha ngā pātai kua pātaihia mai ki a mātou mō te Big Berkey. E kī ana te kaihanga ka taea e tēnei tātari te tango i ngā poke maha atu i ētahi atu tātari. Heoi, kāore i rite ki ā mātou whiringa tātari kē atu, kāore a Big Berkey i whai tiwhikete motuhake ki ngā paerewa NSF/ANSI.
I muri i te 50 hāora o te rangahau me te whakamātautau taiwhanga motuhake i ngā kereme a te kaihanga Big Berkey, kāore i te tino ōrite ngā hua o ā mātou whakamātautau, me ngā hua o tētahi atu taiwhanga i kōrero mātou me tētahi atu taiwhanga tuatoru e wātea ana ngā hua ki te marea. Ki tā mātou whakaaro he whakamārama anō tēnei i te hiranga o te tiwhikete NSF/ANSI: ka taea e te tangata te whakatau hoko i runga i te whakataurite mahi pono. Hei tāpiri, nā te mea he nui ake te pūnaha Big Berkey, he utu nui ake, he uaua ake hoki te tiaki i ngā ipu me ngā tātari i raro i te totohu, kāore mātou e taunaki ahakoa kua whakamanahia.
He nui ake te utu o ngā pūnaha me ngā tātari o Berkey i ērā atu kōwhiringa tātari wai, ā, he iti ake te watea ki te whakamahi. Kāore ngā kereme mahi a ngā kaihanga i whakamanahia motuhaketia e ngā paerewa ā-motu.
E kī ana a New Millennium Concepts, te kaihanga o te Big Berkey, ka taea e te tātari te tango i te neke atu i te kotahi rau ngā poke, he nui ake tēnei i ngā tātari whāngai-papatipu kua arotakehia e mātou. I whakamātauhia e mātou ēnei kereme i runga i te tauine iti, ā, kāore i rite tonu ā mātou hua ki ngā hua taiwhanga i tonoa e New Millennium. Ina koa, ko ngā hua mai i te taiwhanga i tonoa e mātou me te taiwhanga i kirimanahia e New Millennium i whakaatu mai kāore te tātari chloroform i rite te whai hua ki te tuatoru o ngā whakamātautau o mua (i pūrongohia hoki i roto i ngā tuhinga hua a New Millennium).
Kāore tetahi o ngā whakamātautau e whakahuatia ana e mātou i konei (kāore ā mātou whakamātautau, ā Envirotek rānei, ā New Millennium contract a Los Angeles County Laboratory rānei) e tutuki ana i te pakari o te whakamātautau NSF/ANSI. Ina koa, i hiahiatia e NSF/ANSI kia rua ngā wā e whiti ana te momo tātari e whakamahia ana e Berkey i te kaha kua whakatauria o te tātari e inehia ana te wai para i mua i te tango inenga. Ahakoa he tino matatau, he ngaio hoki ngā whakamātautau katoa e kirimanahia ana e mātou me New Millennium, ki tā mātou mōhio, he iti ake te mahi a ia whakamātautau. Nā te mea kāore tetahi o ngā whakamātautau i whakahaerehia ki ngā paerewa NSF/ANSI katoa, kāore he huarahi mārama hei whakataurite tika i ngā hua, hei whakataurite rānei i te mahi whānui o te tātari Burkey ki ngā mea kua whakamatautauria e mātou i mua.
Ko tētahi wāhanga i whakaaetia e te katoa ko te tango i te mata mai i te wai inu, e whakaatu ana i te pai o te mahi a Big Berkey ki te tango i ngā konganuku taumaha. Nō reira, ki te mea he raruraru tōu ki te mata, ki ētahi atu konganuku rānei i roto i tō wai, he pai pea te tirotiro i a Big Berks hei mahi rangitahi.
Haunga te uauatanga o te whakatairite i ngā hua taiwhanga taupatupatu, kāore a New Millennium Concepts i whakautu mai ki ngā tono uiui maha hei matapaki i ā mātou kitenga. I te nuinga, he māramatanga koretake tā ā mātou pūrongo mō ngā pūnaha a Berkey, he rerekē tēnei i te nuinga o ngā kaihanga tātari.
Mō te tātari wai o ia rā, he iti ake te nuinga o ngā tātari ipu me raro i te totohu kua whakamanahia e te NSF/ANSI, he watea ake, he iti ake te utu ki te hoko me te tiaki, ā, he māmā ake hoki te whakamahi. Ka whakaratohia hoki e rātou te kawenga e pā ana ki te whakamātautau motuhake me te mārama.
Kia maumahara ko te nuinga o ngā pūnaha wai ā-tāone he mea haumaru, nō reira, ki te kore koe e mōhio he raruraru kei te rohe, kāore pea koe e hiahia ki te tātari mō ngā take hauora. Mena he āwangawanga nui tōu mō te whakarite mō ngā āhuatanga ohorere, whakaarohia ngā tohutohu mai i tā mātou aratohu whakarite mō ngā āhuatanga ohorere, kei roto ko ngā hua me ngā tohutohu mō te pupuri i te wai ma kia wātea.
Mai i te tau 2016, kua tirotirohia e au tā mātou aratohu mō ngā tātari wai, tae atu ki ngā ipu me ngā pūnaha i raro i te totohu. He kairangahau NOAA o mua a John Holecek, ā, kua whakahaerehia e ia ngā whakamātautau kounga hau me te wai mā mātou mai i te tau 2014. I whakaputa ia i ngā otinga whakamātautau, ā, i mahi tahi me ngā taiwhanga motuhake mō Wirecutter ki te tuhi i tēnei aratohu me te aratohu tātari ipu. Kua whakamanahia a EnviroMatrix Analytical e te Tari Hauora Tūmatanui o California ki te whakamātautau i te wai inu i ngā wā katoa.
He rongonui ngā pūnaha tātari Big Berkey me ngā pūnaha rite mai i Alexapure me ProOne (i mua ko Propur) i waenga i te hunga e whakawhirinaki ana ki te wai puna, kei roto pea ngā poke ka tangohia e ngā tipu maimoatanga wai ā-tāone. He nui hoki te hunga e tautoko ana i a Burkey i waenga i ngā tohunga whakarite mō ngā āhuatanga ohorere me ngā hunga whakahē a te kāwanatanga. 1 Ka pānuitia e ngā kaihokohoko Berkey ēnei pūnaha hei taputapu haumaru ohorere, ā, e ai ki ētahi whakatau tata ka taea e rātou te whakarato wai inu tātari ki te 170 tāngata ia rā.
Ahakoa te take o tō hiahia ki a Berkey, ki tētahi atu pūnaha tātari wai rānei, me whakanui mātou ko te nuinga o ngā wai ā-rohe i te Hononga o Amerika he tino ma i te tīmatanga. Kāore he tātari e taea te tango i ngā poke kāore anō kia kitea, nō reira, ki te kore he raruraru e mōhiotia ana, kāore pea koe e hiahia ki tētahi tātari.
E kī ana ngā kaihanga o te Big Berkey ka taea e te taputapu te tango i te neke atu i te kotahi rau ngā poke (he nui atu i tētahi atu tātari whāngai-papa kua arotakehia e mātou). Nā te mea kāore tēnei tātari i te tiwhikete NSF/ANSI (he rerekē i ngā tātari katoa e taunakihia ana e mātou i roto i ētahi atu aratohu), kāore he pūtake pakari hei whakarite ki ētahi atu tātari kua whakamatautauria e mātou i mua. Nō reira i whakatau mātou ki te whakahaere whakamātautau motuhake hei ngana ki te tārua i ētahi o ēnei hua.
Hei whakamātautau i ēnei kereme, pērā i te whakamātautau ipu, i whakarite a John Holecek i tāna i kī ai ko ngā "otinga raruraru" ā, i whakahaerehia mā roto i tētahi pūnaha Big Berkey (he tātari Black Berkey kei roto). Kātahi ka tukuna e ia ngā tauira o te otinga me te wai tātari ki a EnviroMatrix Analytical, he taiwhanga motuhake kua whakamanahia e te Kāwanatanga o California, hei tātari. Hei whakahaere i te whakamātautau Big Burkey, i whakarite ia i ngā otinga e rua: tētahi kei roto he nui te mata rewa, me tētahi kei roto he chloroform. Ka hoatu he whakaaro mō te whai huatanga whānui o te tātari e pā ana ki ngā konganuku taumaha me ngā matū waro.
I whakarite a John i ngā tauira whakahaere kia tutuki, kia hipa rānei i ngā kukū poke kua tohua i roto i te tiwhikete NSF/ANSI (150 µg/L mō te mata me te 300 µg/L mō te chloroform). E ai ki te whakamātautau tae Berkey (ataata), i muri i te whakaū i te tāutanga me te mahi tika o te tātari, ka rere ia i te karani o te otinga poke i roto i te Berkey ka maka te tātari (wai me tetahi atu mea i puta i roto i te tātari). Hei ine i te otinga poke, ka tātarihia e ia e rua karani wai katoa i roto i te Burkey, ka tangohia he tauira whakahaere mai i te karani tuarua, ka kohia e ia e rua ngā tauira whakamātautau o te tātari mai i roto. Kātahi ka tukuna ngā tauira whakahaere me ngā tauira wai rere ki EnviroMatrix Analytical hei whakamātautau. Nā te mea he tino pōturi te chloroform, ā, "e hiahia ana" ki te mimiti me te hono atu ki ētahi atu matū kei roto, ka whakaranua e John te chloroform ki roto i te otinga poke i mua tata tonu i te tātari.
Ka whakamahia e EnviroMatrix Analytical te ine i te hau chromatography-mass spectrometry (GC-MS) hei ine i te chloroform me ētahi atu pūhui waro mimiti (VOC rānei). I inehia te ihirangi mata mā te whakamahi i te ine i te papatipu plasma coupled inductively coupled (ICP-MS) e ai ki te Tikanga EPA 200.8.
He rerekē te āhua o ngā hua o EnviroMatrix Analytical, ā, he tautoko anō hoki i ngā kereme a New Millennium. Kāore i te tino whai hua ngā tātari pango Berkey ki te tango i te chloroform. I tētahi atu taha, he tino pai tā rātou mahi ki te whakaiti i te mata. (Tirohia te wāhanga e whai ake nei mō ngā hua katoa.)
I tohaina e mātou ngā hua o ā mātou taiwhanga ki a Jamie Young, he kaimātai matū, he rangatira/kaiwhakahaere hoki o tētahi taiwhanga whakamātautau wai raihana o New Jersey (i mōhiotia i taua wā ko Envirotek) i raro i te mana whakahaere o New Millennium Concepts (kaihanga o te pūnaha Big Berkey) i whakatūria i te tau 2014. Ko tāu ake whakamātautau tēnei. He tātari Black Berkey tēnei. I whakaū a 2 Young i ā mātou kitenga me te chloroform me te mata.
Kua whakahaua e New Millennium ētahi atu whakamātautau i mua, tae atu ki tētahi i te tau 2012 i whakahaerehia e te Komihana Ahuwhenua o te Rohe o Los Angeles/Te Tari Taumaha me te Ine Taiao Toxicology Laboratory; i roto i tēnei pūrongo, kua whakarārangihia te chloroform (PDF) hei Black Berkey e ai ki ngā paerewa o te tari (EPA, ehara i te mea ko tētahi o ngā poke i tangohia e NSF/ANSI). Whai muri i te whakamātautau i te tau 2012, i whakawhitia te mahi paitini ki te Tari Hauora Tūmatanui o Los Angeles. I whakapā atu mātou ki te DPH, ā, i whakaūhia e rātou he tika te pūrongo taketake. Engari i whakaahuahia e New Millennium te whakamātautau a Young hei "wāhanga hou" ā, ko ana hua ko ngā mea hou kua whakarārangihia i roto i te Birkey Water Knowledge Base, e puritia ana e New Millennium hei whakarārangi i ngā hua whakamātautau me te whakautu i ngā pātai e pātaihia pinepine ana i runga i tētahi paetukutuku motuhake.
Kāore i te ōrite ngā tikanga whakamātautau a Wirecutter, Young me te Rohe o Los Angeles. Nā te mea kāore tetahi o ēnei e tutuki ana i ngā paerewa NSF/ANSI, kāore he pūtake paerewa mō te whakataurite i ngā hua.
Nō reira, kāore tō mātou whakaaro whānui mō te pūnaha Big Berkey e whakawhirinaki nui ana ki ngā hua o ā mātou whakamātautau. He ngāwari te whakamahi i te Big Berkey, ā, he iti hoki te utu, nō reira ka tūtohu mātou i tētahi tātari ipu whāngai-papatipu noa mō te nuinga o ngā kaipānui, ahakoa e mahi ana te Berkey i ngā mea katoa e kīia ana e te New Millennium ka taea e ia te mahi hei tātari.
I tapahia hoki e mātou ētahi tātari Black Berkey kia kite i te āhua o te hanganga, me te kimi taunakitanga kei roto i ēnei tātari "neke atu i te" ono ngā momo huānga tātari, e ai ki te tari hokohoko a Berkey. I kitea e mātou ahakoa he nui ake, he kikī ake hoki te tātari Berkey i ngā tātari Brita me 3M Filtrete, te āhua nei he rite tonu te tikanga tātari: he waro whakahohe kua whakakiia ki te kapia whakawhiti katote.
Kei roto ngā pūnaha tātari Berkey i te kāwai nui o ngā tātari whāngai-papatipu. Ka whakamahia e ēnei taputapu ngāwari te papatipu hei utu i te wai pūtake mai i te rūma o runga mā te tātari mata pai; ka kohia te wai kua tātarihia ki te rūma o raro, ā, ka taea te tohatoha mai i reira. He tikanga whai hua tēnei, ā, he whānui te whakamahinga, ā, he tauira noa iho ēnei o ngā tātari ipu.
He tino whai hua ngā tātari Berkey mō te rongoā i ngā wai inu kua poke i te mata. I roto i ā mātou whakamātautau, i whakaitihia e rātou ngā taumata mata mai i te 170 µg/L ki te 0.12 µg/L noa iho, he nui atu i te whakaritenga tiwhikete NSF/ANSI mō te whakaiti i ngā taumata mata mai i te 150 µg/L ki te 10 µg/L, iti iho rānei.
Engari i roto i ā mātou whakamātautau me te chloroform, i ngoikore te mahi a te tātari Black Berkey, i whakaitihia te ihirangi chloroform o te tauira whakamātautau mā te 13% noa iho, mai i te 150 µg/L ki te 130 µg/L. Me whakaitihia te NSF/ANSI mā te 95% mai i te 300 µg/L ki te 15 µg/L, iti iho rānei. (I whakaritea tā mātou otinga whakamātautau ki te paerewa NSF/ANSI o te 300 µg/L, engari nā te āhua pōturi o te chloroform ka tere te hanga i ngā pūhui hou, ka mimiti rānei, nō reira ka heke tōna kukū ki te 150 µg/L i te wā i whakamātautauhia ai. Engari ka hopukina hoki e te whakamātautau EnviroMatrix Analytical (ētahi atu pūhui waro pōturi ka taea e te chloroform te whakaputa, nō reira e whakapono ana mātou he tika ngā hua.) I ngoikore hoki te mahi a Jamie Young, he miihini whakamātautau wai raihana nō New Jersey nāna i whakahaere te wāhanga whakamātautau hou mō ngā New Millennium Concepts, me te chloroform mai i te tātari Black Berkey.
Heoi, e kī ana a New Millennium Concepts i runga i te pouaka tātari ka whakaitihia e te tātari Black Berkey te chloroform mā te 99.8% ki "i raro iho i ngā rohe ka kitea i roto i te taiwhanga." (Ko te āhua nei i ahu mai tēnei tau i ngā hua whakamātautau i whakahaerehia e te Los Angeles County Laboratory i te tau 2012. Kei te wātea ngā hua whakamātautau [PDF] i roto i te pūtake mātauranga Berkey Water, e hono ana ki (engari ehara i te wāhanga o) te pae matua o Berkey.)
Kia mārama ai, kāore mātou, a Envirotek, me te Rohe o Los Angeles i tārua i te kawa NSF/ANSI Paerewa 53 katoa e whakamahia ana mō ngā tātari taumaha pērā i te Black Berkey.
I roto i tā mātou take, i whakahaerehia e mātou he whakamātautau taiwhanga i muri i te tātaritanga a ngā Black Berkeys i ētahi karani wai kua whakaritea ki te kukū tohutoro NSF/ANSI. Engari me tu atu ngā tātari whāngai-papa i te rua o te kaha rere kua whakatauria i mua i te whakamātautau i te tiwhikete NSF/ANSI. Mō te tātari Black Berkey, ko te tikanga he 6,000 karani.
Pērā i a mātou, i whakarite a Jamie Young i te otinga whakamātautau ki te Paerewa 53 o te NSF/ANSI, engari kāore i uru ki te kawa Paerewa 53 katoa, e hiahiatia ana kia 6,000 karani o te otinga poke i whakamahia e Black Berries kia puta mā roto i te tātari. I kōrero ia i roto i āna whakamātautau he pai te mahi a te tātari me te mata, ā, i whakaū i ā mātou ake kitenga. Heoi, i kī ia kāore e tutuki i a rātou ngā paerewa tango NSF i muri i te tātari tata ki te 1,100 karani—neke atu i te kotahi hautoru o te roanga ora o te New Millennium 3,000-karani mō ngā tātari Black Berkey.
E whai ana te Rohe o Los Angeles i tētahi tikanga motuhake a te EPA, arā, kotahi noa te tauira 2-rita o te otinga tauira ka puta mā te tātari. Kāore i rite ki a mātou me Young, i kitea e te rohe kua tangohia e te tātari Black Berkey te chloroform kia rite ki ngā paerewa whakamātautau, i tēnei wā neke atu i te 99.8%, mai i te 250 µg/L ki raro iho i te 0.5 µg/L.
Nā te kore ōrite o ngā hua o ā mātou whakamātautau ki ērā mai i ngā taiwhanga e rua i tonoa e Burkey, ka whakaroa mātou ki te taunaki i tēnei tātari, ina koa ka kitea e koe ētahi atu kōwhiringa kua whakamanahia motuhake e whakautu ana i ēnei pātai tuwhera katoa.
I te nuinga o te wā, e tautoko ana ō mātou wheako whakamātautau i tō mātou tūnga: e taunaki ana mātou i ngā tātari wai me te tiwhikete NSF/ANSI, engari kāore a Berkey i te whai tiwhikete pēnei. Nā te mea he tino pakari, he mārama hoki ngā paerewa tiwhikete NSF/ANSI: ka taea e te katoa te pānui i ēnei i runga i te paetukutuku NSF. Ko ngā taiwhanga motuhake kua whakaaetia mō te whakamātautau tiwhikete NSF/ANSI he tino whaimana. I a mātou e tuhi ana mō tēnei aratohu, i kōrero mātou ki a NSF, ā, i mōhio mātou he nui ake i te $1 miriona te utu hei whakahaere i te whakamātautau tiwhikete o ngā matū katoa e kīia ana e New Millennium Concepts ka tangohia e te tātari Black Berkey. I kī a New Millennium e whakapono ana ia kāore e tika te tiwhikete NSF, me te kī ko te utu tētahi atu take kāore anō kia whakahaerehia he whakamātautau.
Ahakoa te mahi tātari tuturu, he nui ngā raruraru tūturu o tēnei tātari, ā, he māmā noa iho ki a mātou te taunaki i tētahi o ā mātou whiringa tātari wai kē atu i mua i te taunaki i te Big Berkey. Tuatahi, he nui ake te utu mō te hoko me te tiaki i te pūnaha Berkey i tētahi atu tātari e taunakihia ana e mātou. Kāore i rite ki ngā tātari e taunakihia ana e mātou, he nui, he ātaahua hoki te Berkey. Kua hangaia kia whakatakotoria ki runga i te tēpu. Engari nā te mea he 19 inihi te teitei, kāore e uru ki raro i te maha o ngā kāpata pakitara, e 18 inihi te nuinga o te wā e tāutahia ana ki runga ake i te papa kaute. He roa rawa hoki te Berkey kia uru ki te nuinga o ngā whirihoranga pouaka whakamātao. Mā tēnei, he iti ake te tūponotanga ka noho matao te wai i Berkey (he ngāwari ki te mahi me tā mātou whiringa kaipuke me te tātari). Kei a New Millennium Concepts he whāriki 5-inihi hei whakangāwari ake i te whakairi i ngā mōhiti i raro i te paipa Big Berkey, engari he nui ake te utu o ēnei whāriki, ā, ka tāpirihia he teitei ki tētahi waeine kua roa kē.
I tuhituhi tētahi kaituhi Wirecutter nāna i pupuri tētahi Big Berkey mō tana wheako: "Haunga te rahi rawa o te taputapu, ka taea e te tāke o runga te whakakī rawa mēnā ka wareware koe ki te whakawātea i te tāke o raro. He taumaha, he matotoru hoki, ā, ka tīmata tonu te tātari. Nō reira me hapai ake e koe kia wātea ai te wāhi mō te tātari waro (he roa, he ngoikore) kātahi ka waiho ki roto i te totohu o raro i mua i te tīmatanga o te turuturu ki runga i te papa, i te kaute rānei."
I tētahi atu ētita o Wirecutter, he Big Berkey tāna (me te tātari uku whakakapinga a te kamupene) engari i mutu wawe te whakamahi. "He koha nā taku hoa rangatira nā te mea i kite ahau i tētahi i te whare o tētahi hoa, ā, i whakaaro ahau he tino reka te wai i puta mai," tana kī. "He tino rerekē te noho tahi me tētahi. He nui, he koretake hoki te wāhi o te papa kaute, i te taha whakapae me te taha poutū. Ā, he iti rawa te totohu o te kīhini i noho ai mātou, ā, he mahi uaua ki te horoi."
E kite ana hoki mātou i te tini o ngā rangatira e amuamu ana mō te tipu o te rimurimu me te huakita, me te nuinga o te wā, ko te hūpē i roto i ā rātou Great Berkies. E mōhio ana a New Millenium Concepts ki tēnei raruraru, ā, e taunaki ana kia tāpirihia ngā Berkey Biofilm Drops ki te wai tātari. He take nui tēnei, ā, kua whakatapua e te tini o ngā kaihokohoko Berkey tētahi whārangi katoa ki tēnei raruraru.
He maha ngā kaihokohoko e whakaae ana he raruraru te tipu o ngā huakita, engari he maha tonu te kī ka puta mai i muri i ētahi tau o te whakamahinga, engari kāore tēnei i te āhua o ā mātou ētita. "I tīmata i roto i te iti iho i te kotahi tau," tana kī. "He haunga te wai, ā, ka tīmata te hongi haunga o ngā rūma o runga me raro. Ka horoia e au, ka horoia ngā tātari ka tangohia kia tae atu ki ngā hononga iti katoa, ā, ka tino horoia te roto o te taputapu. I roto i ngā rā e rua, e toru rānei. I muri i ētahi rā ka noho noa te haunga o te wai, kātahi ka poke anō. I mutu taku whakamahi i a Birki, ā, ka pōuri ahau."
Hei tango katoa i te rimurimu me te paru huakita mai i te tātari Black Berkey, horoia te mata ki te Scotch-Brite, me mahi anō hoki mō ngā puna wai o runga me raro, ā, hei whakamutunga, rerehia he wai mā te tātari. Me nui te tiaki mō tētahi mea kua hangaia hei whakamarie i te tangata mō tō rātou wai.
Mena kei te aro nui koe ki te whakarite mō ngā āhuatanga ohorere, ā, e hiahia ana koe kia wātea te wai ma i ngā wā ohorere, ka tūtohu mātou kia whakamahia ngā hua rokiroki wai i roto i tā mātou Aratohu Whakarite mō ngā Āhua ohorere. Mena he tātari wai pai tāu e hiahia ana, ka tūtohu mātou kia rapu koe i tētahi tātari kua whakamanahia e te NSF/ANSI, pērā i ā mātou aratohu ki ngā Ipu Tātari Wai Pai rawa atu me ngā Tātari Wai Pai rawa atu i raro i te Totohu.
E rua ngā rauemi rerekē e whakamahia ana e te nuinga o ngā tātari taumaha hei tango i ngā poke i roto i te wai. Ka mimiti, ka herea rānei e te waro whakahohe ngā matū waro, tae atu ki ngā wahie me ngā whakarewa hinu, te maha o ngā patu pepeke me te maha o ngā rongoā. Ka tangohia e ngā kapia whakawhiti katote te maha o ngā konganuku rewa i roto i te wai, ka whakakapi i ngā konganuku taumaha paitini (pērā i te mata, te mercury me te cadmium) ki ngā konganuku taumaha māmā ake, kāore e kino te nuinga (pērā i te konutai, te wāhanga matua o te tote tēpu).
Ko tā mātou whiringa tātari ipu (mai i a Brita) me ngā tātari i raro i te totohu (mai i a 3M Filtrete) he mea hanga pēnei. Kāore a New Millennium Concepts e whakaatu ana i te hanganga o te tātari Black Berkey, engari he maha ngā kaihokohoko e whakanui ana i tōna hoahoa, tae atu ki a TheBerkey.com: "Ko tā mātou huānga tātari Black Berkey he mea hanga mai i te ranunga motuhake o ngā momo pāpāho e ono neke atu. Ko te tauira he maha ngā momo, tae atu ki te waro anga kokonati kounga teitei, kua whakauruhia katoa ki roto i tētahi hanganga tino kiato kei roto he miriona ngā pūwero moroiti." I te wā i tapahia ai e mātou he takirua tātari Black Berkey, i hangaia mai i ngā katote kua whakakīia kei roto he poraka waro whakahohe e whakawhiti ana i te kapia. Ka whakaū a Jamie Young i tēnei kitenga.
He kaituhi matua a Tim Heffernan, he tohunga ia ki te kounga o te hau me te wai, me te whai huatanga o te pūngao o te kāinga. He kaituhi o mua ia mō The Atlantic, Popular Mechanics me ētahi atu maheni ā-motu, ā, i uru atu ia ki Wirecutter i te tau 2015. E toru āna pahikara, kāore he taputapu.
Kua whaimanahia ēnei tātari, hū me ngā ipu wai hei tango i ngā poke me te whakapai ake i te kounga o te wai inu i roto i tō whare.
Whai muri i te whakamātautau i ngā puna wai mōkai e 13 (me te huri i tētahi hei taonga ngaungau), i kitea e mātou ko te Puna Putiputi Ngeru te mea pai rawa atu mō te nuinga o ngā ngeru (me ētahi kurī).
Ko Wirecutter te ratonga taunaki hua a The New York Times. Ka whakakotahi ā mātou kairīpoata i ngā rangahau motuhake me ngā whakamātautau pakari (i ētahi wā) hei āwhina i a koe ki te whakatau hoko tere me te maia. Ahakoa kei te rapu koe i ngā hua kounga, kei te rapu tohutohu āwhina rānei, ka āwhina mātou i a koe ki te kimi i ngā whakautu tika (i te wā tuatahi).
