Kupu Whakataki: I te wā e whiriwhiri ana i tētahi kaiwhakapai wai, ko te tohu "NSF Certified" he paerewa koura mō te pono. Engari ka whakamanahia e tētahi kaiwhakapai wai kua whakamanahia e te NSF te haumaru tino? He aha te tikanga o te "tohu NSF"? Kua whakaarohia e koe te pūtaiao kei muri i tēnei hiri me tōna hononga nui ki tētahi wāhanga iti engari he mea nui i roto i tō kaiwhakapai wai—te hiri rapa? Ka rukuhia e tēnei tuhinga ngā mahi takirua a te NSF, ka whakautua ngā pātai matua, ā, ka whakakitea me pēhea te mahi tahi a ngā wāhanga matua hei tiaki i tō wai.
1. NSF: Ngā Kaupapa Takirua hei Tūāpapa Pūtaiao me te Kaitiaki Haumaru
E rua ngā hinonga matua o te NSF e hanga ana i ngā parepare mō te ahunga whakamua o te pūtaiao me te haumaru o ngā hua:
- Te Pūtaiao ā-Motu (NSF):
- He tari ā-motu o Amerika i whakatūria i te tau 1950 me te kaupapa matua he whakatairanga i te ahunga whakamua o te pūtaiao.
- Ka tautoko i ngā rangahau taketake (hei tauira, te tūhuratanga ātea, te ira tangata, te pūtaiao taiao), ka whakarato i te pūtake mātauranga mō te hauora o te motu, te whai rawa, te oranga ngākau, me te haumarutanga.
- Mā āna rangahau ka whakakahangia te auahatanga hangarau me ngā ahumahi hangarau teitei.
- NSF (i mua ko NSF International):
- He whakahaere motuhake, kore-moni, kore-kāwanatanga i whakatūria i te tau 1944, e mahi ana hei mana whakahaere o te ao mō te hauora me te haumaru tūmatanui.
- Pakihi Matua: Te whakawhanake i ngā paerewa hua, ngā ratonga whakamātautau me te tiwhikete e kapi ana i te wai, te kai, ngā pūtaiao hauora, me ngā taonga kaihoko.
- Whāinga: Whakaitihia ngā mōrearea hauora me te tiaki i te taiao.
- Mana Whakahaere: E mahi ana i roto i te 180+ whenua, he Pokapū Mahi Tahi me te Whakahaere Hauora o te Ao (WHO) mō te haumaru kai, te kounga wai, me te haumaru o ngā taputapu hauora.
- He maha ngā paerewa maimoatanga wai inu kua tangohia hei Paerewa ā-Motu o Amerika (Paerewa NSF/ANSI).
2. Tiwhikete NSF: Te Paerewa mō te Mahi me te Haumaru o te Kaiwhakaora Wai
I te mea e tipu haere ana te āwangawanga o ngā kaihoko mō te haumaru o te wai inu, kua noho ko ngā mīhini horoi wai hei whiringa matua mō te tiaki hauora o te kāinga. Ko te pūnaha tiwhikete a te NSF te paearu pūtaiao e aromatawai ana mēnā ka tutuki i te mīhini horoi te whakatutuki i ana kereme horoi.
- Ngā Paerewa Pūmau: Ka whakatūhia e te NSF ngā paerewa pūmau mō ngā kaihoro wai. Ko ētahi tauira matua ko:
- NSF/ANSI 42: E aro ana ki ngā pānga ataahua (te reka, te kakara, ngā matūriki pēnei i te chlorine).
- NSF/ANSI 53: E whakahau ana i ngā whakaritenga mō te whakaiti i ngā poke hauora motuhake (hei tauira, te mata, ngā patu pepeke, ngā VOC, ngā THM, te asbestos). Ko te tikanga o te tiwhikete he whakaiti whai hua.
- NSF/ANSI 401: E aro ana ki ngā poke e puta ake ana/e tūpono ana (hei tauira, ētahi rongoā, ngā matū whakaputa pepeke).
- NSF P231 (Ngā Pūwhakamātautau Wai Moroiti): Ka arotake motuhake i ngā pūnaha mō te whakaiti i ngā moroiti (hei tauira, ngā huakita, ngā huaketo, ngā whēkau).
- NSF P535 (Mō te Mākete Haina): I hangaia mō ngā taputapu maimoatanga wai inu i Haina. E kapi ana i te haumaru o ngā rauemi, ngā whakaritenga mahi taketake, me te manatoko i ngā kereme whakaiti mō ngā poke motuhake (hei tauira, te mata, te mercury, PFOA/PFOS, BPA).
- Pātai Matua kua Whakautua: He aha te tikanga o te māka NSF?
- Whakamārama Hira: EHARA te tiwhikete NSF i te pūnaha "whakamātautau" (hei tauira, Tohu A, B). Kāore he mea e kiia ana he "tohu NSF". Ko te tiwhikete NSF he manatoko Paahi/Hē ki ngā paerewa motuhake.
- Te Tikanga Matua: Ko te tikanga o te kaihoro wai e kī ana he tiwhikete NSF kua paahitia e ia te whakamātautau me te aromatawai NSF motuhake mō tētahi, neke atu rānei o ngā paerewa motuhake (hei tauira, NSF/ANSI 53, NSF P231) e kīia ana e ia ka tutuki. Ka aro ia paerewa ki ngā āheinga whakaiti poke rerekē, ki ngā whakaritenga haumaru rauemi rānei.
- Arotahi ki te Kaihoko: Kaua e rapu i tētahi "taumata" kāore i te kitea, engari me aro tonu ngā kaihoko ki ngā paerewa NSF kua paahitia e te hua (ko te tikanga kua whakarārangihia i roto i ngā whakaritenga hua, ka taea rānei te manatoko mā te pātengi raraunga ipurangi a NSF). Hei tauira, ko tētahi kaihoroi e kī ana he "Tiwhikete NSF" tērā pea kua paahitia e ia te NSF/ANSI 42 anake (whakapaipai ataahua), ehara i te NSF/ANSI 53 (whakaiti i ngā poke hauora). He mea nui te mōhio ki ngā tiwhikete motuhake.
- Uara Mākete:
- Te Whakawhirinakitanga o te Kaihoko: Ko ngā tiwhikete NSF motuhake kua tohua mārama he tohu matua mō te whakawhirinakitanga o ngā kaihoko, e tohu ana kua oti te whakamātautau motuhake a te hua mō ngā āheinga kua kīia (te whakaiti i te poke, te haumaru o ngā rauemi).
- Painga Waitohu: Mō ngā kaihanga, ko te whiwhi tiwhikete NSF uaua (pēnei i te P231) he tohu kaha mō te kounga o te hua, e whakarei ake ana i te ingoa o te waitohu me te whakataetae.
- Ngā Akoranga Take:
- Aqualuxe Maha-Parakore: Mā te whakamahi i te hangarau poraka waro pēhanga-teitei, ka tutuki i a ia te 99.99% te whakaiti i ngā huaketo, te 99.9999% te whakaiti i ngā huakita, ā, ka whai hua te whakaiti i te 100+ ngā poke. Koinei anake te pūnaha kotahi-wāhanga o te ao kua whakamanahia ki te NSF P231 (Ngā Kaiwhakaora Miroiti). (E whakaatu ana i te angitu i tētahi paerewa miroiti pakari, ehara i te "taumata" pōuriuri)
- Philips Water: E 20 o āna mīhini horoi wai whakamuri i angitu ki te whiwhi i te tiwhikete NSF P535, koia te kamupene ā-rohe tuatahi i Haina ki te mahi pera, ā, i whakakaha ake i tōna kaiārahi mākete. (Ngā āhuatanga matua e tutuki ana i tētahi paerewa whānui kua whakaritea mō Haina)
3. Te "Toa Kore i Waiatatia" o te Kaiwhakapai Wai: Te Tūranga Hiranga o ngā Hiri Rapa
I roto i te hoahoa matatini o te kaihoroi, he iti ngā hiri rapa engari he "kaitiaki" nui. Kāore te tiwhikete NSF e aromatawai noa i te mahi tātari; ko ana whakaritenga "haumaru rauemi" e pā tika ana ki ngā wāhanga nui pēnei i ngā hiri.
- Mahi Matua: Kia tino hiritia te ara wai (ngā whare tātari, ngā hononga paipa), kia ārai i ngā turuturu me te poke i waenga i te wai kāore i tukatukahia me te wai kua tukatukahia. He mea nui ēnei mō te mahi haumaru me te whai hua.
- Ngā Mōrearea Kounga: Ka taea e ngā hiri kounga-kore te turuturu, te pakaru, te tuku rānei i ngā matū kino. Ka tino whakararu tēnei i te mahi purenga, ka poke te wai kua rongoatia, ka kino te waeine, ka kino ngā taonga (hei tauira, ngā papa waipuke), ā, ka tūpono he mōrearea hauora. Ahakoa he tātari mahi-teitei kua whakamanahia, ka taea e te pakaru, te poke rānei o te hiri te whakararu i te haumaru o te pūnaha katoa me te mana o te tiwhikete NSF.
4. Te Whakapakari i te Raina Parepare Whakamutunga:Ngā Hiri Rapa Mahi-Teitei
He tohunga mātou ki te whakarato i ngā otinga hiri rapa mahi-teitei mō te umanga horoi wai, me te mārama ki te hiranga o ēnei mea mō te pono o te pūnaha me te pupuri i te mana whaimana o te tiwhikete NSF:
- Haumaru Rauemi: Kōwhiringa pakari o ngā rauemi e tutuki ana i ngā whakaritenga NSF (hei tauira, te tutuki i te NSF/ANSI 61 mō ngā wāhanga pūnaha wai inu), ka whakamatautauria kia kore ai e mimiti, e heke, e poke rānei i te wā roa e pā ana ki te wai, te tiaki i te parakore o te wai, me te tutuki i ngā ture haumaru rauemi a te NSF.
- Te Hanganga Tika: Mā ngā tikanga whakaputa matatau ka tino tika te mahi me te mahi hiri pai rawa atu mō te pumau mō te wā roa i roto i ngā pūnaha wai uaua.
- Te Whakataurite Pūmau: Mā te whakahaere kounga maha-wāhanga (e hangai ana ki ngā whakaritenga whakamātautau NSF) mai i ngā rauemi mata ki ngā taonga kua oti te whakaoti, ka oati te pono me te roa o ngā hua.
- Mahi Tino Pai:
- Ātete Pakeke Tino Pai: Ka mau tonu te ngāwari me te hiri i raro i te makuku roa, ngā pāmahana rerekē, me ngā taumata pH, ka roa ake te ora me te whakarite kia tutuki mō te wā roa.
- Pono: Ka tino whakaiti i ngā turuturu, ngā hekenga o te mahi, ngā whakatikatika rānei nā te rahunga o te hiri, ka tukuna he mahi roa, he mahi haumaru, kāore he āwangawanga.
- Whakaritenga: Te kaha ki te whakarato i ngā otinga hiri kua whakaritea kia rite ki ngā hoahoa waitohu/tauira motuhake o te kaihoroi me ngā whakaritenga tiwhikete NSF.
Whakamutunga: Tiwhikete ≠ Kounga Korekore, Ngā Wāhanga Tika e Whakapūmau ana i te Haumaru Tonu
Ko te tiwhikete NSF he whakamana pūtaiao e tutuki ana te kaihoro wai i ngā paearu haumaru me te mahi motuhake mā te whakamātautau pakari, e whakarato ana i ngā aratohu mārama mō ngā kaihoko. Kia maumahara, ko te tohu tēnei ko te paahitia o ngā paerewa tuturu, ehara i te "taumata" ruarua. Heoi, ko te haumaru me te mana tiwhikete mō te wā roa o te kaihoro wai e whakawhirinaki ana ki te hiranga me te pakari o ōna wāhanga matua o roto, pērā i ngā hiri rapa. Ka mahi tahi rātou, ka hanga he mekameka katoa e tiaki ana i te wai inu whare. Ko te whiriwhiri i tētahi kaihoro wai me ngā tiwhikete NSF kua whakamāramahia mārama (hei tauira, NSF/ANSI 53, NSF P231, NSF P535) me te whakarite i te kounga o ōna wāhanga matua (ina koa ko ngā hiri haumaru-nui) ko te kōwhiringa atamai mō ngā kaihoko e rapu ana i te wai inu hauora, pono, mō te wā roa.
