Ua kūkulu ʻia kaʻu hana ma luna o kona kahua.
ʻO ka mea pōʻino, ʻaʻohe pane like no ka pono o kahi kānana wai. Ma ʻAmelika Hui Pū ʻIa, ua hoʻoponopono ʻia ka lako wai lehulehu e ka EPA e like me ke Kānāwai Wai Maʻemaʻe, a pono e hoʻokō ka wai e haʻalele ana i nā hale hana hoʻomaʻemaʻe wai lehulehu i nā kūlana maikaʻi koʻikoʻi.

Ma muli o ka ʻike: ʻo ka ʻelemakule o kou hale a i ʻole kou kaiāulu, ʻoi aku ka nui o ka pilikia o ka haumia ma lalo o ka wai. Ua ʻōlelo ka US Environmental Protection Agency "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 maʻamau i kū ʻole i nā kikoʻī o kēia manawa.

Inā inu kou ʻohana ma mua o ʻelua a ʻekolu galani o ka wai inu i ka lā, a laila ʻoi aku ka maikaʻi o kahi kānana ma lalo o ka poho holoi ma mua o kahi kānana pahu.

Ke hoʻohālikelike ʻia me nā kānana poho, ʻoi aku ka nui o ka mana o nā kānana ma lalo o ka poho a ʻoi aku ka lōʻihi o ke ola lawelawe - ʻo ka maʻamau he mau haneli galani a me ʻeono mahina a ʻoi aku paha, ʻoiai ʻo ka hapa nui o nā kānana poho he 40 galani a me ʻelua mahina. No ka mea, hoʻohana nā kānana ma lalo o ka poho i ke kaomi wai ma kahi o ka umekaumaha e hoʻokuke i ka wai ma o ke kānana, hiki i kā lākou mau kānana ke ʻoi aku ka paʻa, no laila hiki iā lākou ke wehe i kahi ākea o nā mea haumia hiki.

Ma hope o ka hoʻāʻo ʻana, ua pani mākou i ka kānana Pur Pitcher i hoʻopau ʻia me kahi kānana Faster Pour Pitcher.
E pili ana kēia alakaʻi i kahi ʻano kikoʻī o ke kānana ma lalo o ka poho wai: ʻo ia hoʻi nā mea e hoʻohana ana i kahi kānana cartridge a hoʻouna i ka wai i kānana ʻia i kahi piula wai ʻokoʻa. ʻO kēia nā kānana ma lalo o ka poho wai kaulana loa. He liʻiliʻi loa ka wahi e lawe ai lākou a he maʻalahi ke hoʻokomo a mālama. Hoʻohana lākou i nā mea adsorbent—ʻo ka maʻamau he kalapona i hoʻāla ʻia a me nā resins hoʻololi ion, e like me nā kānana pahu wai—e hoʻopaʻa a hoʻopau i nā mea haumia. ʻAʻole mākou e kamaʻilio e pili ana i nā kānana, nā ʻōnaehana osmosis hoʻohuli, a i ʻole nā ​​​​​​piula a i ʻole nā ​​​​​​mea hoʻokaʻawale ʻē aʻe i hoʻokomo ʻia ma nā piula wai.
I mea e hōʻoia ai e paipai wale mākou i nā kānana hilinaʻi, ua koi mau mākou ua hala kā mākou koho i ka palapala hōʻoia maʻamau o ka ʻoihana: ANSI/NSF. ʻO ka American National Standards Institute a me NSF International he mau hui pilikino waiwai ʻole e hana pū ana me ka EPA, nā ʻelele o ka ʻoihana, a me nā loea ʻē aʻe e hoʻokumu i nā kūlana maikaʻi koʻikoʻi a me nā protocol hoʻāʻo no nā tausani o nā huahana, me nā kānana wai. ʻO nā keʻena hōʻoia nui ʻelua no nā mea hoʻomaʻemaʻe wai ʻo NSF International ponoʻī a me ka Water Quality Association (WQA). Ua ʻae piha ʻia nā mea ʻelua e ANSI a me ka Canadian Standards Council ma ʻAmelika ʻĀkau, hiki ke hoʻāʻo ʻia no ka palapala hōʻoia ANSI/NSF, a pono nā mea ʻelua e hoʻokō me nā kūlana hoʻāʻo like a me nā protocol. Hiki i ke kānana ke hoʻokō wale i nā kūlana hōʻoia ma hope o kona hala ʻana i kona ola i manaʻo ʻia. E hoʻohana i nā laʻana "paʻakikī" i hoʻomākaukau ʻia, ʻoi aku ka haumia ma mua o ka hapa nui o ka wai piula wai.
Ma kēia alakaʻi, kālele mākou i nā kānana i loaʻa nā palapala hōʻoia no ka chlorine, ke kēpau, a me VOC (aka volatile organic compound).
He mea nui ka palapala hōʻoia chlorine (ma lalo o ANSI/Standard 42) no ka mea ʻo ka chlorine ke kumu nui o ka wai paipa "ʻono ʻole". Akā, he hana hoʻopunipuni kēia: ua hala nā ʻano kānana wai āpau i kāna palapala hōʻoia.
He mea paʻakikī ke hoʻokō ʻana i ka hōʻoia alakaʻi no ka mea ʻo ia hoʻi ka hōʻemi ʻana i nā hopena waiwai i ke alakaʻi ma mua o 99%.

Ua hoʻohaiki hou mākou i kā mākou ʻimi a koho i nā kānana i hōʻoia hou ʻia ma lalo o ka ANSI/NSF Standard 401 hou, kahi e uhi ana i nā mea haumia e kū mai ana, e like me nā lāʻau lapaʻau, e loaʻa nui ana ma nā wai o ʻAmelika. Pēlā nō, ʻaʻole i loaʻa i nā kānana āpau ka palapala hōʻoia 401, no laila he hui koho loa nā kānana i loaʻa iā ia (a me ka palapala hōʻoia kēpau a me VOC).
Ma kēia ʻāpana paʻa, a laila e ʻimi mākou i nā mea me ka liʻiliʻi o 500 galani. Ua like kēia me ke ola kānana o kahi o 6 mau mahina ma lalo o ka hoʻohana nui ʻana (2¾ galani i kēlā me kēia lā). No ka hapa nui o nā ʻohana, ua lawa kēia e hoʻokō i nā pono inu a me ka kuke ʻana i kēlā me kēia lā. (Hāʻawi ka mea hana i kahi papa hana hoʻololi kānana i ʻōlelo ʻia, maʻamau i nā mahina ma mua o nā galani; hahai mākou i kēia mau ʻōlelo aʻoaʻo i kā mākou loiloi a me nā helu kumukūʻai. Paipai mākou e hoʻohana mau i ka mea pani a ka mea hana mua ma kahi o kahi kānana ʻaoʻao ʻekolu.)
ʻO ka mea hope loa, ua kaupaona mākou i ke kumukūʻai mua o ka ʻōnaehana holoʻokoʻa a me ke kumukūʻai e hoʻomau nei no ka hoʻololi ʻana i ke kānana. ʻAʻole mākou i hoʻonohonoho i kahi palena kumukūʻai haʻahaʻa a kiʻekiʻe paha, akā hōʻike kā mākou noiʻi ʻoiai ke kumukūʻai mua mai US$100 a US$1,250, a ʻo ke kumukūʻai kānana mai US$60 a kokoke i US$300, ʻaʻole i ʻoi aku ka maikaʻi o kēia mau ʻokoʻa. ʻO ke kumu hoʻohālike pipiʻi i nā kikoʻī.

Eia kekahi, ke ʻimi nei mākou i:

Ua hala pū ʻo Aquasana AQ-5200 i ka hōʻoia o 15 "nā mea haumia e kū mai ana", e hoʻonui nei i nā ʻōnaehana lako wai lehulehu, me ka bisphenol A, ibuprofen, a me ka estrone (kahi estrogen i hoʻohana ʻia no ka pale ʻana i ka hāpai ʻana); No nā hui PFOA a me PFOS-fluorine i hoʻohana ʻia e hana i nā mea ʻaʻole e pipili, a loaʻa iā ia kahi ʻōlelo aʻoaʻo olakino EPA i Pepeluali 2019. (I ka manawa o ke kūkākūkā ʻana, ʻekolu wale nō mea hana o kēia ʻano kānana i loaʻa ka palapala hōʻoia PFOA/S, kahi e hoʻolilo ai i kēia i mea koʻikoʻi.) Ua hala pū ia i ka palapala hōʻoia VOC. ʻO ke ʻano kēia e hiki iā ia ke hoʻoneʻe pono ma mua o 50 mau pūhui organik like ʻole, me nā pesticides he nui a me nā mea mua o ka ʻoihana.
Ma waho aʻe o ke kalapona i hoʻāla ʻia a me nā resins hoʻololi ion (ʻo ka hapa nui, inā ʻaʻole nā ​​​​mea āpau, he mea maʻamau nā kānana ma lalo o ka pahu), hoʻohana pū ʻo Aquasana i ʻelua mau ʻenehana kānana hou e loaʻa ai ka palapala hōʻoia. No nā chloramines, hoʻohui ia i ke kalapona catalytic, ʻo ia ke ʻano porous o ke kalapona i hoʻāla ʻia i hana ʻia ma ka mālama ʻana i ke kalapona me ke kinoea wela kiʻekiʻe. No Cryptosporidium lāua ʻo Giardia, hana ʻo Aquasana i nā kānana ma ka hoʻemi ʻana i ka nui o ka pore i 0.5 microns, kahi i lawa ai e hopu kino iā lākou.
ʻO ka hōʻoia maikaʻi loa o ka kānana Aquasana AQ-5200 ke kumu nui i koho ai mākou iā ia. Akā ʻo kona hoʻolālā a me nā mea hana e hoʻolilo iā ia i mea kū hoʻokahi. Hana ʻia ka faucet i ka metala paʻa, e like me ke kaula T-ʻano e hoʻopili ai i ke kānana i ka paipu. Hoʻohana kekahi mau mea hoʻokūkū i ka plastic no hoʻokahi a ʻelua paha o lākou, e hōʻemi ana i nā kumukūʻai, akā e hoʻonui ana i ka pilikia o ke kaula cross-threading a me nā hewa hoʻonohonoho. Hoʻohana ʻo AQ-5200 i nā mea hoʻopili compression e hōʻoia i kahi sila paʻa a palekana ma waena o kāu 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-in maʻalahi, ʻaʻole palekana loa. Loaʻa ka faucet AQ-5200 i ʻekolu mau hoʻopau (nickel brushed, chrome polished a me ke keleawe ʻaila), a ʻaʻohe koho a 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 kānana ʻē aʻe, me ka Aquasana AQ-5300+ ma lalo, ua like ka nui me ka ʻōmole lita. Ma hope o ke kau ʻana i ke kānana ma ke kākoʻo hoʻopaʻa ʻana, ʻo ke ana o AQ-5200 he 9 ʻīniha ke kiʻekiʻe, 8 ʻīniha ka laulā, a me 4 ʻīniha ka hohonu; ʻO 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 ke keʻena poho holoi, hiki ke hoʻokomo ʻia i loko o kahi ākea haiki ʻaʻole hiki ke hoʻokipa ʻia e nā ʻōnaehana nui aʻe, a waiho i kahi ākea no ka mālama ʻana ma lalo o ke poho holoi. Pono ʻoe ma kahi o 11 ʻīniha o kahi ākea kū pololei (i ana ʻia mai luna mai o ka pā) e ʻae i ka hoʻololi ʻana i ke kānana, a ma kahi o 9 ʻīniha o kahi ākea ākea ʻole ma ka paia o ke keʻena e hoʻokomo i ka pā.
Ua loiloi maikaʻi ʻia ka AQ-5200 no nā kānana wai, me 4.5 mau hōkū mai loko mai o 800 mau loiloi ma ka pūnaewele Aquasana (mai loko mai o ʻelima mau hōkū), a me 4.5 mau hōkū mai loko mai o 500 mau loiloi ma Home Depot.
ʻO ka mea hope loa, ʻo ke kumukūʻai o Aquasana AQ-5200 i kēia manawa ma kahi o US$140 no ka ʻōnaehana holoʻokoʻa (ʻaneʻane kokoke i US$100), a ʻo ke kumukūʻai o kahi hoʻonohonoho o nā kānana pani he US$60 (ʻo kēlā me kēia manawa pani ʻeono mahina he US$120 i kēlā me kēia makahiki). ʻO Aquasana AQ- ʻO ka 5200 kekahi o nā huahana waiwai nui loa o kā mākou mau mea hoʻokūkū, he mau haneli kālā ke kumu kūʻai haʻahaʻa ma mua o kekahi mau hiʻohiʻona i hōʻoia ʻole ʻia. Loaʻa i ka hāmeʻa kahi timer e hoʻomaka e kani ke pono ʻoe e hoʻololi i ke kānana, akā ke paipai nei mākou e hoʻonohonoho pū ʻoe 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 ka nui o ke kahe ʻana 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. Ma keʻano laulā, ke manaʻoʻiʻo nei mākou ua hoʻopau ʻia kēia mau hemahema liʻiliʻi e kona liʻiliʻi. Inā ʻike ʻoe makemake ʻoe i ke kahe a me ka mana kiʻekiʻe, loaʻa iā Aquasana AQ-5300+ kahi kahe i helu ʻia he 0.72 gpm a me 800 galani, akā me ka papa hana hoʻololi kānana ʻeono mahina like, loaʻa iā Aquasana Claryum Direct Connect kahi kahe a hiki i 1.5 gpm a ua helu ʻia i 784 galani a me ʻeono mahina.
