I tā mātou tono atu ki a Ocean kia tūtohu mai i tētahi pitī tātari wai, ka mutu noa iho tā mātou tono, nō reira, anei ngā kōwhiringa i tirohia e mātou.
Tērā pea ka whiwhi moni tātou mai i ngā hua e tukuna ana i tēnei whārangi, ā, ka whai wāhi atu hoki ki ngā kaupapa hononga. Pānuihia atu >
Ko te noho wai tonu he wero tonu—i runga i te rongonui o ngā pounamu wai rahi-karani me ngā pounamu e kī ana i te maha o ngā aune me inu e koe i tētahi wā—ā, ka taea e te ipu wai tātari te āwhina i a koe kia noho hauora. Ka taea te whakatutuki i ō whāinga wai o ia rā mā te whiriwhiri i ngā ipu wai tātari hei utu mō ngā pounamu whakakorekore. Ko te tikanga, ka whakapai ake ngā ipu tātari wai i te reka me te kakara o tō wai tap. Ka taea hoki e ētahi tauira te whakaiti i ngā poke pērā i ngā konganuku taumaha, ngā matū, ngā kirihou moroiti rānei. Ahakoa kei te inu wai koe māu ake, kei te whakakī i te mīhini kawhe, kei te whakarite rānei ki te tunu kai, kua tātarihia e mātou ngā kōwhiringa maha hei kimi i te ipu tātari wai tino pai māu.
Ko te wai mai i ngā tipu maimoatanga wai tūmatanui i te Hononga o Amerika e kiia ana ko ētahi o ngā mea tino haumaru o te ao, engari ko ngā mea rerekē pērā i te mata i te puna wai o Flint, Michigan, ka taea te whakararuraru i te tangata. He tohunga mātou ki ngā ipu tātari wai e whakaputa ana i te wai whakahauora me te wai ma. He rite tonu te hangarau taketake o te maha o ngā tātari, ahakoa ko ētahi e whakaiti ana, e tango ana rānei i ētahi atu poke pea, ko ētahi he mea hanga hei tiaki i ngā kohuke e pai ana mōu. Ka whakanui hoki mātou kei te tutuki, kei te whai tiwhikete rānei te hua ki ngā paerewa i whakatakotoria e te National Science Foundation/National Standards Institute me te Water Quality Association, he kaiarotake tuatoru motuhake.
He rite tonu te hoahoa o te nuinga o ngā ipu tātari wai: he puna wai o runga, o raro hoki, me te tātari i waenganui. Ringihia te wai puna ki te wāhanga o runga, kātahi ka tatari kia tōia e te kaha ā-papa mā roto i te tātari ki te wāhanga o raro. Engari he maha atu anō ngā kōwhiringa, pērā i te whakatau i te nui o te wai e whakamahia ana e tō whānau me te nui o te wāhi kei roto i tō pouaka whakamātao. Haunga te utu o te ipu, me whakaaro anō hoki koe ki te utu o ngā tātari me te maha o ngā karani ka taea e rātou te horoi i mua i te whakakapinga (nā te mea ko ētahi o tātou e tino hiahia ana ki te whakakī tonu i ā tātou pounamu wai).
Ko te Brita Large Water Filter Pitcher te pai rawa atu o tā mātou ipu tātari wai whānui nā te mea he nui te kaha o te 10-kapu, he utu iti, ā, he roa te wā e whakamahia ana hei tātari. Mā te taupoki hono o te hāka, e mōhiotia ana ko te Tahoe, ka taea e koe te whakakī tere atu i ngā tauira e hiahia ana kia tangohia e koe te taupoki katoa. He rama tohu anō hoki kei roto e whakaatu ana mēnā kei te pai te tātari, kei te mahi, me whakakapi rānei.
Ka tūtohu mātou i te Tātari Elite Retrofit, he mea whaimana ki te whakaiti i te mata, te mercury, te BPA, me ētahi patupatu me ngā matū pumau. He nui ake ngā poke e hopukina ana e ia i te tātari mā noa, ā, e ono marama te roa—e toru ngā wā roa ake. Heoi, e kī ana ētahi kiritaki i muri i ētahi marama ka āraia te tātari, ka whakapotohia tōna roanga. Ki te kore koe e hiahia ki te whakakapi i tetahi mea i roto i ngā wā tata nei, ko te utu ā-tau mō ngā tātari ka tata ki te $35.
He tokomaha e mōhio ana ki a LifeStraw mō āna tātari wai whakaora ora me āna tātari puni, engari he hoahoa anō hoki tā te kamupene i ngā hua ataahua, whai hua mō tō kāinga. Ko te utu hokohoko mō te LifeStraw Home Water Filtration Pitcher he $65 pea, ā, e wātea ana i roto i ngā tae maha i roto i tētahi ipu karāhe porowhita hou e pai ana ki te hunga e ngana ana ki te whakaiti i te whakamahinga kirihou i roto i ō rātou kāinga. He pai te pā o te pouaka silicone ōrite, he tiaki i ngā karawarawa me ngā pakaru, ā, he pai te pupuri.
He pūnaha wāhanga-rua tēnei tātari, ā, ka taea te whakahaere i ngā poke neke atu i te 30 e kore e taea e ētahi atu tāke wai te whakahaere. He tiwhikete NSF/ANSI tēnei hei whakaiti i te chlorine, te mercury me te mata. E tutuki ana hoki i ngā paerewa maha kua whakamatautauria e ngā taiwhanga whaimana mō ngā patu pepeke, ngā patu taru me ētahi matū pumau, ā, ka taea te pure i te wai kua pōuriuria e te onepu, te paru, ētahi atu paru rānei. E ai ki te kamupene ka taea te whakamahi i te tātari i te wā e whakatūpatohia ana te wai kohua, engari mēnā i tupu tēnā i tōku rohe, ka kohuatia tonu e au te wai.
Ko te painga o te tātari e rua ngā wāhanga, ka taea e te LifeStraw Home te tango i te nui o ngā poke. Ko te ngoikoretanga, me whakakapi ia wāhanga i ngā wā rerekē. Tata ki te kotahi tau te roa o te kiriuhi, ā, me whakakapi ngā tātari waro me te whakawhiti katote iti ake i ia rua marama (tata ki te 40 karani). Ko te utu mō ia tau he tata ki te $75, he nui ake tēnei i te nuinga o ngā ipu kē atu i runga i tēnei rārangi. Kua kite hoki ngā kaiwhakamahi he puhoi te tātari, nō reira he pai ake te whakakī i te ipu i mua i te whakahokinga ki roto i te pouaka whakamātao. (He mea atawhai tēnei ki ētahi atu ipu kē atu.)
Kāore te tātari wai Hydros Slim Pitch 40-aune e whakamahi i te pūnaha tātari tāke-rua paerewa, engari he pai ake mō te tere. Ka whakamahia e tēnei ipu iti engari kaha he tātari waro anga kokonati hei tango i te 90% o te haurehu me te 99% o te paru. Kāore e aro ki ētahi atu poke pea. Kāore he kakau o tēnei ipu rokiroki e rima-kapu, engari he ngāwari ki te pupuri me te whakakī, ā, he mea pai mō ngā ipu angiangi.
Tērā pea ka whakaaro tētahi whānau he tamariki nohinohi ā rātou e tohe ana ki te riringi i ā rātou ake inu he mea kino te kore o te kakau, engari ka uru ngāwari ki te tatau o te pouaka whakamātao me te kore e noho katoa te wāhi. Kei te Hydro Slim Pitcher hoki he pouaka kanapa, ā, kei te wātea te tātari i roto i ngā tae maha pērā i te papura, te kakariki raima, te kikorangi me te whero, e hoatu ana he pa whaiaro ake. Ka taea hoki te whakauru i te tātari ki te werohanga wai hei tāpiri i te kakara hua, otaota rānei.
Me whakakapi ngā tātari Hydros i ia rua marama, ā, e $30 pea te utu i te tau. Ka taea hoki te whakawhiti me ētahi atu hua Hydros.
Ko te tātari rere-rahi a Brita he mea mō te hunga e kino ana ki te tatari. Kei roto katoa i te ingoa: ina ringihia he wai, ka haere mā roto i te tātari waro whakahohe kua tāutahia ki te waha. Ko te hunga kua whakamātau ki te whakakī i tētahi pounamu wai karani e mōhio ana he tukanga maha-taahiraa mō tētahi hāka noa. Me whakakī te tāke wai kia kotahi te iti rawa, kātahi ka tatari kia haere mā roto i te tātari. He torutoru meneti noa iho, engari e mōhio ana koe ki te kīwaha: kāore te wai e tātarihia. Ka whakakorea e Brita Stream te tukanga tatari.
Ko te ngoikoretanga, ehara i te mea he tātari poke kaha. Kua whakamanahia hei tango i te reka me te haunga o te chlorine me te pupuri i te fluoride, ngā kohuke me ngā electrolytes. He tātari hautai tēnei, he rerekē ki ngā putanga whare kirihou e mōhiotia ana i ētahi atu hua Brita. Me whakakapi ngā tātari i ia 40 karani, ā, mō te maha o ngā kete, tata ki te $38 te utu mō te tuku mō te tau.
He utu nui te Aarke purifier mō te $150, engari he mea hanga mai i ngā rauemi kounga teitei, akuaku pērā i te karāhe me te maitai kore waikura, ā, kei roto hoki he tātari ka taea te whakamahi anō. Koinei pea te kōwhiringa tino pai mō te taiao i runga i tēnei rārangi nā te mea kāore e whakamahia he tātari kirihou ka mutu ki te para i muri i te whakamahinga. Engari, ka whakamahia e te pūnaha ngā matūriki tātari i whakawhanakehia e Aarke i te mahi tahi me te kamupene hangarau wai BWT.
Ka whakaitihia e ēnei kirikiri te chlorine, ngā konganuku taumaha me te tauine raima, ā, ka āwhina i te ārai i ngā paru i runga i ō rihi. E 32 karani te roa o ngā kirikiri i mua i te whakakapinga. E rua ngā momo kirikiri a te kamupene: ngā kirikiri parakore me ngā kirikiri kukū, e tāpiri ana i te konupora me te huri i te wai paipa hei kawakore. Kei waenga i te $20 ki te $30 ngā utu mō te kete e toru.
He rerekē te āhua o te ipu LARQ PureVis: e rua ngā taahiraa o te ipu hei tātari i te wai, hei ārai hoki i te tipu o ngā huakita. Ka uru tuatahi te wai ki roto i te tātari tipu NanoZero hei tango i te chlorine, te mercury, te cadmium me te parahi. Kātahi ka tukuna e te "UV wand" o te ipu te mārama hei patu i ngā huakita me ngā huaketo i roto i te wai.
Me utu anō hoki te LARQ i ia rua marama mā te whakamahi i te rihi USB-A kua whakaurua. Kei roto hoki i te kete katoa he taupānga iOS anake hei āwhina i a koe ki te aroturuki i te wā me huri ngā tātari me te nui o te wai e whakamahia ana e koe. Ko te utu mō tēnei pounamu wai kei roto i ngā taputapu he tata ki te $170, engari ka pai pea ki te hunga kua taunga ki ngā taputapu atamai me te aroturuki i ngā inenga whaiaro (koia te take i hangaia ai e te kamupene tā mātou pounamu wai atamai tino pai). E rua ngā taumata tātari a te LARQ, ā, ahakoa he roa ake te ora i te nuinga o ngā tātari kei runga i tēnei rārangi, ko te utu mō te tau kotahi ka $100 te utu mō te tātari taumata-whakauru, tae atu rānei ki te $150 mō te putanga moni.
Ko ngā whare nui ake, ko te hunga rānei e inu ana i te karani wai i te rā, me hiahia pea ki te Tātari Wai PUR PLUS 30-Kapu. He hoahoa angiangi, hōhonu hoki tēnei ipu nui, ā, he paipa hiri, ā, ko te utu hokohoko he $70 pea. Kua whakamanahia ngā tātari PUR PLUS ki te whakaiti i te 70 atu poke, tae atu ki te mata, te mercury me ētahi patupatu. He mea hanga mai i te waro whakahohe mai i ngā anga kokonati. He pūtake kohuke tōna e whakakapi ana i ētahi kohuke taiao pērā i te konupūmā me te konupora hei whakarato i te reka hou, me te kore he reka, he haunga rānei o te chlorine. Engari e 40 karani, e rua marama rānei te roa. Ko te utu mō te tau kotahi ina hoko maha-pūkete he $50 pea te nuinga.
He tau whaiaro te nui o te wai e tika ana kia inuhia e koe, ehara i te mea e waru ngā karāhe wai e rongohia ana e tātou i a tātou e tipu ake ana. Mā te whai wai reka mā te ringa ka āwhina i a koe ki te whakatutuki i ō whāinga wai. He iti ake te utu o ngā ipu tātari wai, ā, he pai ake hoki mō te taiao i te penapena wai pounamu kotahi te whakamahinga. Hei whiriwhiri i te ipu tika māu, me whai whakaaro koe ki ētahi mea.
Ko te kirihou te rauemi matua mō te maha o ngā ipu, ā, he rauemi matua hoki mō te maha o ngā tātari. Ahakoa he uaua ki te kimi hua kāore he kirihou, he maha ngā kōwhiringa. Ko ētahi e tuku ana i ngā rauemi kounga teitei pērā i te karāhe, te maitai kore waikura, ngā wāhanga silicone kai-kai rānei. Tirohia ngā taunakitanga a te kaihanga kia kite ai mēnā kei te hiahia koe ki te horoi ā-ringa i ngā wāhanga, ki te maka rānei ki roto i te mīhini horoi rihi. Nā te rongonui o ngā ipu tātari wai kua kite hoki ngā kaihanga e aro nui ana ki te ataahua, nō reira kāore e uaua ki te kimi i tētahi kōwhiringa ātaahua ka koa koe ki te waiho ki runga i tō kaute.
He rerekē te utu, te hoahoa me ngā mea ka whakaitihia, ka tangohia rānei e ngā tātari. Ko te nuinga o ngā tātari i roto i tēnei arotake he waro whakahohe, e mimiti ana i te hauota, e whakaiti ana hoki i te asbestos, te mata, te mercury me ngā matū waro pūngāwerewere. Mena he pātai motuhake āu, pēnei i te tango i ētahi matū, i ngā konganuku taumaha rānei, tirohia te paetukutuku a te kaihanga mō ngā raraunga mahi.
Ehara mātou i te taiwhanga, nō reira e pai ake ana mātou ki ngā hua kua whakamanahia e te NSF International, e te Water Quality Association rānei. Heoi, ka whakarārangihia e mātou ngā hua e "tutuki" ana i ngā paerewa whakamātautau taiwhanga motuhake.
Whakaarohia te nui o te wai e inuhia ana e tō whānau, me te maha o ngā karani wai ka taea te pupuri i te tātari i mua i te whakakapinga. Me whakakapi te tātari kia taea ai e te tāke te mahi tonu. Ko ētahi ka tukatuka noa i te 40 karani wai, nō reira, me whakakapi pea te tātari i roto i ngā whare maroke, whare nui rānei i mua i te rua marama. He pai ake pea te whiriwhiri i tētahi tātari kua hangaia kia roa ake te ora. Kaua hoki e wareware ki te tatau i te nui o te utu hei whakakapi i roto i te tau.
Ko ngā ipu tātari wai te mea pai rawa atu mō te hunga e hiahia ana ki te whakapai ake i te reka o ā rātou wai tap—ka taea e ngā ipu katoa o tēnei rārangi te mahi i tēnā. Ka taea e ētahi ipu tātari wai te tango i ngā poke me ngā paru tāpiri, ko ētahi kāore anō kia whakahaeretia, pērā i ngā matū pumau. (Hei whakamōhiotanga, i whakaputa te EPA i ngā ture kua whakaarohia mō te PFA i te marama o Poutū-te-rangi.) Mena kei te hiahia koe ki te kounga o te wai, ka taea e koe te tirotiro i te pūrongo kounga wai ā-tau i runga i te paetukutuku EPA, he pātengi raraunga Environmental Working Group kei roto i te Wai Tap, te whakamātautau rānei i tō wai kāinga.
Ko ngā ipu tātari wai, kāore e tango i ngā huakita. Ko te nuinga o ngā ipu tātari wai e whakamahi ana i ngā tātari waro, i ngā tātari whakawhiti katote rānei, kāore e whakaiti i ngā moroiti pēnei i te huakita. Heoi, ka taea e LifeStraw Home me LARQ te whakaiti, te pehi rānei i ētahi huakita mā te whakamahi i ngā tātari kiriuhi me te mārama UV. Mena he mea nui te whakahaere i ngā huakita, tirohia ngā kōwhiringa purenga wai, tētahi pūnaha tātari rerekē rānei mā te whakamahi i te osmosis whakamuri.
Tirohia te pukapuka ā-ringa mō te kaipupuri wai kia kitea ai ko ēhea ngā wāhanga me horoi ā-ringa, ko ēhea hoki ka taea te horoi ki te mīhini horoi rihi. Heoi anō, kia tino horoia te ipu. Ka taea e ngā huakita, te harore, me ngā kakara kino te kohikohi i roto i ngā taputapu kīhini katoa, ā, kāore he rerekētanga o ngā ipu tātari wai.
E hoa mā, kāore koutou e matewai i ngā wā katoa. Ahakoa ko te utu iti, te oranga tonutanga, te hoahoa pai rānei tō kaupapa matua, kua kitea e mātou ngā ipu tātari wai pai rawa atu mō tō kāinga. He ipu tātari wai Brita nui mō te wai tap me te wai inu me te tohu whakakapinga tātari SmartLight + 1 tātari tino pai. Ko tā mātou whiringa mō te tātari pai rawa atu. Ka whakahoutia te tātari Brita tawhito, kia watea ake ai. He taupoki, he kakau whānui me te tātari mohio mō ngā hua ka roa ake te ora engari he iti ake te utu. He nui ake. Ahakoa ko tēhea te mea e whiriwhiria e koe, kia tino hurihia te tātari i ia wā kia whiwhi ai i te painga nui me te whakaiti i ngā poke.
Neke atu i te 150 tau ki muri ka tīmata a Popular Science ki te tuhituhi mō te hangarau. I te wā i whakaputaina ai e mātou tā mātou putanga tuatahi i te tau 1872, kāore he mea e kiia nei ko te "tuhinga taputapu", engari mēnā i pērā, ko tā mātou kaupapa ki te whakamārama i te ao auaha mō ngā kaipānui o ia rā, ko te tikanga kei roto katoa mātou i te ao. Kei te whakatapua katoa a PopSci ki te āwhina i ngā kaipānui ki te whakatere i te tini o ngā taputapu kei te mākete.
He tekau tau te roa o te wheako o ā mātou kaituhi me ngā ētita ki te tirotiro me te arotake i ngā taputapu hiko a te kiritaki. He pai ki a tātou katoa ā tātou hiahia – mai i te oro kounga teitei ki ngā kēmu ataata, ngā kāmera me ētahi atu – engari ina whakaarohia e mātou ngā taputapu i waho atu i tō mātou whare noho tata, ka whakapau kaha mātou ki te kimi i ngā reo me ngā whakaaro pono hei āwhina i te tangata ki te whiriwhiri i te mea pai rawa atu. E mōhio ana mātou kāore mātou e mōhio ki ngā mea katoa, engari e harikoa ana mātou ki te whakamātautau i te koretake o te tātari ka puta mai i te hokohoko tuihono kia kore ai e hiahiatia e ngā kaipānui.
