ʻO ka poʻe e inu ana ma mua o kekahi mau galani o ka wai inu i kēlā me kēia lā, ʻoi aku ka māʻona me kahi ʻōnaehana kānana ma lalo o ka poho wai e like me ka Aquasana AQ-5200.

Ua hoʻāʻo au i nā kānana wai no Wirecutter mai ka makahiki 2016.

A ua ʻike pono wau i kā mākou mau koho āpau, no ka mea, he mea nui ka nohona holoʻokoʻa, ka lōʻihi, a me ka maʻalahi o ka hoʻohana ʻana no kahi hāmeʻa āu e hoʻohana ai i nā manawa he nui i ka lā. Ua noiʻi a kākau ka ʻepekema NOAA mua ʻo John Holecek i nā alakaʻi kānana wai mua o Wirecutter, ua hana i kāna hoʻāʻo ponoʻī, ua kauoha i nā hoʻāʻo kūʻokoʻa hou aʻe, a ua aʻo mai iaʻu i ka nui o kaʻu ʻike. Ua kūkulu ʻia kaʻu hana ma luna o kona kahua.
ʻO ka mea pōʻino, ʻaʻohe pane hoʻokahi e kūpono i nā mea āpau inā pono ʻoe i kahi kānana wai. Ma ʻAmelika Hui Pū ʻIa, hoʻoponopono ʻia nā lako wai lehulehu e ka EPA ma lalo o ke Clean Water Act, a pono e hoʻokō ka wai e haʻalele ana i nā hale hana mālama wai lehulehu i nā kūlana maikaʻi loa. Akā, ʻaʻole i hoʻoponopono ʻia nā mea haumia āpau. Pēlā nō, hiki i nā mea haumia ke komo i loko o ka wai ma hope o ka haʻalele ʻana i ka hale hana mālama ma o nā paipu leakage (PDF) a i ʻole ma o nā paipu ponoʻī. Hiki i ka mālama ʻana i ka wai ma ka hale hana (a i ʻole ka haʻalele ʻole ʻia) ke hoʻonui i ka leaching ma nā pipelines ma lalo—e like me ka mea i hana ʻia ma Flint, Michigan.
No ka ʻike pono ʻana i ka mea i loko o ka wai o kāu mea hoʻolako ke haʻalele ia i ka hale hana, hiki iā ʻoe ke nānā i ka hōʻike hilinaʻi mea kūʻai aku a kāu mea hoʻolako kūloko ma ka pūnaewele; inā ʻaʻole, pono nā mea hoʻolako wai lehulehu āpau e hāʻawi iā ʻoe i kahi CCR ma ke noi. Akā ma muli o ka hiki ke haumia ma lalo o ka wai, ʻo ke ala wale nō e maopopo ai i ka wai i loko o kou home, ʻo ia ke uku i kahi keʻena hoʻokolohua maikaʻi wai kūloko e hoʻāʻo ʻia.
Ma ke ʻano he kānāwai maʻamau: ʻo ka ʻelemakule o kou home a i ʻole kou kaiāulu, ʻoi aku ka nui o ka pilikia o ka haumia ma lalo o ka wai. Wahi a ka EPA "ʻoi aku ka nui o nā hale i kūkulu ʻia ma mua o 1986 e hoʻohana i nā paipu kēpau, nā mea paʻa a me ka solder" - nā mea kahiko i maʻamau i ka wā ma mua a ʻaʻole i kūlike i nā code o kēia manawa. Hoʻonui pū ka ʻelemakule i ka hiki ke haumia ka wai honua hoʻoilina o ka ʻoihana i hoʻoponopono mua ʻia, hiki ke lilo i mea pilikia, ʻoiai ke hui pū ʻia me ka hōʻino ʻana o nā paipu lalo o ka honua e pili ana i ka makahiki.
Inā inu kou ʻohana ma mua o ʻelua a ʻekolu galani o ka wai inu i kēlā me kēia lā, ʻoi aku ka maikaʻi o kahi kānana wai ma lalo o ka poho holoi ma mua o kahi kānana hue. Hāʻawi ka ʻōnaehana ma lalo o ka poho holoi i ka wai inu i kānana ʻia ma ke noi me ka ʻole o ke kali ʻana i ka pau ʻana o ke kaʻina kānana, e like me ka pahu wai. ʻO ke kānana "ma ke noi" ʻo ia hoʻi hiki i ka ʻōnaehana ma lalo o ka poho holoi ke hāʻawi i ka wai lawa no ka kuke ʻana - no ka laʻana, hiki iā ʻoe ke hoʻopiha i kahi ipuhao me ka wai i kānana ʻia e kuke ai i ka pasta, akā ʻaʻole ʻoe e hoʻopiha hou i ka hue no kēlā.
ʻOi aku ka lōʻihi o ka mana a me ke ola o nā kānana ma lalo o ka poho holoi ma mua o nā kānana canister—ʻo ia hoʻi he mau haneli galani a me ʻeono mahina a ʻoi aku paha, i hoʻohālikelike ʻia me 40 galani a me 40 galani no ka hapa nui o nā kānana canister. ʻelua mahina. A no ka mea, hoʻohana nā kānana ma lalo o ka poho holoi i ke kaomi wai ma mua o ka umekaumaha e hoʻokuke i ka wai ma o ke kānana, hiki i kā lākou mau kānana ke ʻoi aku ka mānoanoa, no laila hiki iā lākou ke wehe i kahi ākea o nā mea haumia hiki.
Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ke kumukūʻai ma mua o nā kānana pitcher, a ʻoi aku ke kumukūʻai o nā pani kānana ma ke ʻano maoli a me ka awelika i ka hala ʻana o ka manawa. Lawe pū ka ʻōnaehana i kahi i loko o ke keʻena poho holoi i loaʻa no ka mālama ʻana.
ʻO ke kau ʻana i kahi kānana ma lalo o ka poho holoi e pono ai ka hoʻokomo ʻana i ka plumbing maʻamau a me ka lako, akā he hana maʻalahi wale nō inā loaʻa i kāu poho holoi kahi lua hoʻokahi. Inā ʻaʻole, pono ʻoe e kīkēkē i kekahi o nā wahi faucet i kūkulu ʻia (ʻike ʻia e like me nā disc i hāpai ʻia ma nā poho holoi kila, a i ʻole nā ​​māka ma nā poho holoi pōhaku synthetic). Me ka ʻole o kahi kīkēkē, pono ʻoe e wili i kahi lua i loko o ka poho holoi, a inā aia kāu poho holoi ma lalo o ke kūʻai, pono nō hoʻi ʻoe e wili i kahi lua i loko o ke kūʻai. Inā loaʻa iā ʻoe kahi mea hoʻokaʻawale kopa, kahi hakahaka ea no ka mea holoi kīʻaha, a i ʻole ka mea pīpī lima ma ka poho holoi, hiki iā ʻoe ke wehe a hoʻokomo i ka faucet ma laila.
Ua hōʻoia ʻia kēia mau kānana wai, nā pahu wai a me nā mea hoʻokaʻawale wai e wehe i nā mea haumia a hoʻomaikaʻi i ka wai inu home.
ʻO kēia alakaʻi e pili ana i kahi ʻano kikoʻī o ka kānana ma lalo o ka poho holoi: ʻo ia hoʻi nā mea e hoʻohana ana i kahi kānana cartridge a hoʻouna i ka wai kānana i kahi faucet ʻokoʻa. ʻO kēia nā kānana ma lalo o ka poho holoi kaulana loa. Lawe lākou i kahi liʻiliʻi a maʻalahi hoʻi e hoʻokomo a mālama. Hoʻohana lākou i nā mea adsorbent—ʻo ka maʻamau ka carbon activated a me nā resins ion-exchange, e like me nā kānana pitcher—e hoʻopaʻa a hoʻopau i nā mea haumia. ʻAʻole mākou e kamaʻilio e pili ana i nā kānana i kau ʻia ma ka faucet, nā ʻōnaehana osmosis hoʻohuli, a i ʻole nā ​​​​​​tank a i ʻole nā ​​​​​​dispenser ʻē aʻe.
I mea e hōʻoia ai ua ʻōlelo wale mākou i nā kānana hiki iā ʻoe ke hilinaʻi, ua hoʻopaʻa mākou ua hōʻoia ʻia kā mākou koho i ke kūlana ʻoihana: ANSI/NSF. ʻO ka American National Standards Institute a me NSF International he mau hui pilikino, ʻaʻole no ka loaʻa kālā e hana pū ana me ka EPA, nā ʻelele ʻoihana a me nā loea ʻē aʻe e hoʻomohala i nā kūlana maikaʻi koʻikoʻi a me nā protocol hoʻāʻo no nā tausani o nā huahana, me nā kānana wai. ʻO nā keʻena hoʻokolohua ʻelua i hōʻoia ʻia no nā kānana wai ʻo NSF International ponoʻī a me ka Water Quality Association (WQA).

No kēia alakaʻi, ke kālele nei mākou i nā kānana i loaʻa nā palapala hōʻoia no ka chlorine, ke kēpau, a me VOC (aka volatile organic compounds).
He mea nui ka palapala hōʻoia chlorine (e like me ANSI/Standard 42) no ka mea ʻo ka chlorine pinepine ke kumu o ka "ʻono maikaʻi ʻole" o ka wai piula. Akā he hōʻike maopopo nō hoʻi ia: Ua hōʻoia ʻia ka aneane o nā ʻano kānana wai āpau.
He mea paʻakikī ke hoʻokō ʻana i ka palapala hōʻoia alakaʻi no ka mea ʻo ia hoʻi ka hōʻemi ʻana i nā hopena waiwai i ke alakaʻi ma mua o 99%.

(I ka manawa o ke kūkākūkā ʻana, ʻekolu wale nō mea hana o ia mau kānana i hōʻoia ʻia e PFOA/S, e hoʻolilo ana i kēia i mea koʻikoʻi.) Ua hōʻoia ʻia hoʻi ʻo VOC. ʻO ke ʻano kēia hiki iā ia ke wehe pono i nā hui organik like ʻole he 50, me nā pesticides he nui a me nā precursors ʻoihana.
Ma waho aʻe o ke kalapona i hoʻāla ʻia a me nā resins hoʻololi ion (maʻamau inā ʻaʻole nā ​​​​kānana āpau ma lalo o ka poho), hoʻohana ʻo Aquasana i ʻelua mau ʻenehana kānana hou e hoʻokō ai i ka palapala hōʻoia. No nā chloramines, hoʻohui ia i ke kalapona catalytic, kahi porous a no laila ʻoi aku ka reactive activated carbon i hana ʻia ma ka mālama ʻana i ke kalapona me kahi kinoea wela kiʻekiʻe. No Cryptosporidium lāua ʻo Giardia, hana ʻo Aquasana i ke kānana ma ka hoʻemi ʻana i ka nui o ka pore i 0.5 microns, liʻiliʻi e hiki ai ke hoʻopaʻa kino iā lākou.
ʻO ka palapala hōʻoia kiʻekiʻe o ka kānana Aquasana AQ-5200 ke kumu nui i koho ai mākou iā ia. Akā ʻo kona hoʻolālā a me nā mea hana hoʻi e hoʻokaʻawale iā ia. Hana ʻia ka faucet i ka metala paʻa, e like me nā T-clamps e hoʻopili ai i ke kānana i ka paipu. Hoʻohana kekahi mau mea hoʻokūkū i ka plastic no kekahi a i ʻole nā ​​​​mea ʻelua, e hōʻemi ana i nā kumukūʻai akā e hoʻonui ana i ka pilikia o ke kaula cross a me ke kau ʻana hewa. Hoʻohana ka AQ-5200 i nā mea hoʻopili compression e hōʻoia i kahi sila paʻa a paʻa ma waena o ka paipu a me ka paipu plastic e lawe ana i ka wai i ke kānana a me ka faucet; hoʻohana kekahi mau mea hoʻokūkū i nā mea hoʻopili push-on maʻalahi, ʻaʻole i palekana. Loaʻa ka faucet AQ-5200 i ʻekolu mau hoʻopau (nickel brushed, chrome polished, a me ke keleawe ʻaila), ʻoiai ʻaʻohe koho o kekahi mau mea hoʻokūkū.
Makemake pū mākou i ke ʻano liʻiliʻi o ka ʻōnaehana AQ-5200. Hoʻohana ia i ʻelua mau kānana, ʻoi aku ka nui o kēlā me kēia ma mua o kahi kini soda; ʻo kekahi mau mea ʻē aʻe, me ka Aquasana AQ-5300+ ma lalo, ua like ka nui me ka ʻōmole lita. Me ke kānana i hoʻokomo ʻia ma ke kākoʻo hoʻopaʻa ʻana, ʻo ke ana o ka AQ-5200 he 9 ʻīniha ke kiʻekiʻe, 8 ʻīniha ka laulā, a me 4 ʻīniha ka hohonu; ʻo ke ana o ka Aquasana AQ-5300+ he 13 x 12 x 4 ʻīniha. ʻO ke ʻano kēia, ʻoi aku ka liʻiliʻi o ka wahi o ka AQ-5200 i loko o kahi keʻena poho holoi, hiki ke hoʻokomo ʻia i nā wahi paʻa kahi e hiki ʻole ai i nā ʻōnaehana nui ke komo, a waiho i kahi hou aʻe no ka mālama ʻana ma lalo o ka poho holoi. Pono ʻoe ma kahi o 11 ʻīniha o kahi kū pololei (i ana ʻia mai luna mai o ka pā) e ʻae ai i ka hoʻololi ʻana i ke kānana, a ma kahi o 9 ʻīniha o kahi ākea i keʻakeʻa ʻole ʻia ma ka paia o ke keʻena e hoʻokomo i ka pā.
Ua loaʻa ka helu maikaʻi loa o ka AQ-5200 no nā kānana wai, e loaʻa ana he 4.5 mai loko mai o 5 mai loko mai o 800 mau loiloi ma ka pūnaewele ʻo Aquasana a me 4.5 mai loko mai o kahi kokoke i 500 mau loiloi ma Home Depot.
ʻO ka mea hope loa, ʻo ke kumukūʻai o kēia manawa o kahi ʻōnaehana piha no ka Aquasana AQ-5200 ma kahi o $140 (kūʻai pinepine ʻia no kahi kokoke i $100) a me $60 no kahi hoʻonohonoho o nā kānana pani ($120 i kēlā me kēia makahiki no kahi pōʻaiapuni pani 6 mahina), ʻo ka Aquasana AQ-5200 ʻO ia kekahi o nā waiwai maikaʻi loa i waena o kā mākou mau mea hoʻokūkū a he mau haneli kālā keu ma mua o kekahi mau hiʻohiʻona me nā palapala hōʻoia liʻiliʻi. Loaʻa i ka ʻāpana kahi timer e hoʻomaka ana e kani ke pono ʻoe e hoʻololi i ke kānana, akā ke paipai nei mākou e hoʻonohonoho i kahi hoʻomanaʻo kalena hou ma kāu kelepona. (ʻAʻole paha ʻoe e poina.)
Ke hoʻohālikelike ʻia me kekahi mau mea hoʻokūkū, ʻoi aku ka haʻahaʻa o ke kahe kiʻekiʻe o ka Aquasana AQ-5200 (0.5 gpm vs. 0.72 a ʻoi aku paha) a me ka haʻahaʻa o ka mana (500 galani vs. 750 a ʻoi aku paha). He hopena pololei kēia o kāna kānana liʻiliʻi kino. Ma keʻano holoʻokoʻa, manaʻo mākou ua kaumaha kēia mau hemahema liʻiliʻi e kona compactness. Inā ʻike ʻoe e pono ana ʻoe i ke kahe a me ka mana kiʻekiʻe, ua helu ʻia ka Aquasana AQ-5300+ ma 0.72 gpm a me 800 galani, akā me ka papa hana hoʻololi kānana ʻeono mahina like, hāʻawi ka Aquasana Clarium Direct Connect i nā helu a hiki i ka 1.5 gpm Flow a i 784 galani a me ʻeono mahina.
