No ka hoʻomaopopo pono ʻana i nā mea i loko o ka wai ke haʻalele ka mea hoʻolako i ka hale hana, hiki iā ʻoe ke ʻike i ka hōʻike hilinaʻi o ka mea kūʻai aku o ka EPA o ka mea hoʻolako kūloko ma ka Pūnaewele; inā ʻaʻole, pono nā mea hoʻolako wai āpau e hāʻawi iā ʻoe i kā lākou CCR e like me kāu koi.

No ka hōʻoia ʻana e paipai wale mākou i nā kānana hilinaʻi, ua koi mau mākou ua hala kā mākou koho i ka palapala hōʻoia maʻamau: ANSI/NSF. ʻO ka American National Standards Institute a me ka NSF International he mau hui waiwai ʻole e hana pū me ka EPA, nā ʻelele ʻoihana, a me nā loea ʻē aʻe e hoʻokumu i nā kūlana koʻikoʻi a me nā protocol hoʻāʻo no nā tausani o nā huahana, me nā kānana wai. ʻO nā laboratories hōʻoia nui ʻelua no ka hoʻomaʻemaʻe wai ʻo NSF International ponoʻī a me ka Water Quality Association (WQA).

Ma kēia alakaʻi, nānā mākou i nā kānana i loaʻa nā palapala hōʻoia chlorine, lead, a me VOC (aka volatile organic compound).
He mea koʻikoʻi ka hōʻoia ʻana o ka chlorine (ma lalo o ANSI/Standard 42) no ka mea, ʻo ka chlorine ka mea maʻamau no ka wai paipu "ʻono ʻino". Akā, ua kokoke kēia i kahi gimmick: kokoke i nā ʻano kānana wai āpau i hala i kāna palapala hōʻoia.

(I ka manawa kūkākūkā, ʻekolu wale nō mea hana o kēia ʻano kānana i loaʻa i ka PFOA / S hōʻoia. ʻoi aku ka maikaʻi o kēia.) Ua hala pū ʻo ia i ka palapala VOC. 'O ia ho'i, hiki iā ia ke ho'opau pono ma mua o 50 mau pūhui mea ola like 'ole, me ka nui o nā pesticides a me nā mea hana mua.
Ma waho aʻe o nā resins carbon activated a me nā ion exchange resins (ʻo ka hapa nui, inā ʻaʻole ʻo nā mea āpau, nā kānana under-tank he mea maʻamau), 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 kahi ʻano porous o ke kalapona hoʻāla i hana ʻia e ka mālama ʻana i ke kalapona me ke kinoea wela wela. No Cryptosporidium a me Giardia, hana ʻo Aquasana i nā kānana ma ka hōʻemi ʻana i ka nui o ka pore i 0.5 microns, ʻo ia ka lawa e hopu kino ai iā lākou.
ʻO ka hōʻoia maikaʻi loa o ka kānana Aquasana AQ-5200 ke kumu nui a mākou i koho ai. Akā ʻo kona hoʻolālā a me nā mea hana hoʻi he mea kū hoʻokahi. Hana ʻia ka faucet me ka metala paʻa, e like me ke ʻano o ke ʻano T e hoʻopili ai i ka 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 kea a me nā hewa hoʻonohonoho. Hoʻohana ʻo AQ-5200 i nā mea hoʻopili e hōʻoia i kahi sila paʻa a palekana ma waena o kāu paipu a me ka paipu plastik e lawe ana i ka wai i ka kānana a me ka faucet; hoʻohana kekahi mau mea hoʻokūkū i nā mea hoʻokomo maʻalahi, ʻaʻole palekana loa. Loaʻa ka faucet AQ-5200 i ʻekolu hoʻopau (brushed nickel, polished chrome and oiled bronze), a ʻaʻohe koho o kekahi mau mea hoʻokūkū.
Makemake pū mākou i ka mea hoʻohālikelike compact o ka ʻōnaehana AQ-5200. Hoʻohana ʻo ia i nā kānana ʻelua, ʻoi aku ka nui o kēlā me kēia ma mua o ka pā soda; ʻO kekahi mau kānana ʻē aʻe, me ka Aquasana AQ-5300+ ma lalo, ʻo ia ka nui o ka ʻōmole lita. Ma hope o ka hoʻokomo ʻana i ka kānana ma ka bracket kau ʻana, ʻo nā ana o AQ-5200 he 9 iniha ke kiʻekiʻe, 8 ʻīniha ākea, a me 4 iniha ka hohonu; ʻO Aquasana AQ-5300+ he 13 x 12 x 4 iniha. ʻO ia ke ʻano o ka AQ-5200 e noho liʻiliʻi loa i loko o ka pahu pahu, hiki ke hoʻokomo ʻia ma kahi ākea ʻaʻole hiki ke hoʻokipa ʻia e nā ʻōnaehana ʻoi aku ka nui, a waiho i kahi nui no ka waiho ʻana ma lalo o ka paila. Pono ʻoe ma kahi o 11 mau ʻīniha o ke ākea kū pololei (ana i lalo mai luna o ka pā) e ʻae i ka hoʻololi ʻana i ka kānana, a ma kahi o 9 mau ʻīniha o kahi ākea ākea ʻole ma ka paia o ke keʻena e hoʻokomo i ka pā.
ʻIke maikaʻi ʻia ka AQ-5200 no nā kānana wai, me nā hōkū 4.5 mai loko o 800 mau loiloi ma ka pūnaewele Aquasana (mai loko o nā hōkū ʻelima), a me 4.5 mau hōkū mai kahi kokoke i 500 mau loiloi ma Home Depot.
ʻO ka mea hope loa, ʻo Aquasana AQ-5200 ke kumukūʻai i kēia manawa ma kahi o US $140 no ka ʻōnaehana holoʻokoʻa (maʻa mau kokoke i ka US $100), a ʻo kahi pūʻulu o nā kānana pani e uku ʻia ʻo US $60 (ʻo kēlā me kēia manawa hoʻololi ʻeono mahina he US $120 i kēlā me kēia makahiki). ʻO Aquasana AQ- ʻO ka 5200 kekahi o nā huahana waiwai nui o kā mākou mea hoʻokūkū, ʻoi aku ka liʻiliʻi o nā haneli kālā ma mua o kekahi mau hiʻohiʻona i hōʻoia ʻia. Aia i loko o ka hāmeʻa kahi manawa e hoʻomaka ai ke kani ʻana i ka wā e pono ai ʻoe e hoʻololi i ka kānana, akā manaʻo mākou e kau pū ʻoe i kahi hoʻomanaʻo hoʻomanaʻo kalena ma kāu kelepona. (ʻAʻole paha ʻoe e poina iā ia.)
Ke hoʻohālikelike ʻia me kekahi mau mea hoʻokūkū, ʻo ka Aquasana AQ-5200 he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (0.5 gpm vs. 0.72 a ʻoi paha) a me ka haʻahaʻa haʻahaʻa (500 galani vs. 750 a ʻoi paha). He hopena pololei kēia o kāna kānana liʻiliʻi kino. Ma keʻano laulā, manaʻo mākou ua hoʻopau ʻia kēia mau hemahema liʻiliʻi e kona compactness. Inā ʻike ʻoe makemake ʻoe i ke kahe kiʻekiʻe a me ka hiki, ua loaʻa iā Aquasana AQ-5300+ ka kahe helu o 0.72 gpm a me 800 galani, akā me ka papa hoʻonohonoho hoʻololi kānana ʻeono mahina, ʻo Aquasana Claryum Direct Connect he kahe kahe a hiki i 1.5 gpm a helu ʻia i 784 galani a me ʻeono mahina.
