ʻO nā kānana ea he mea nui i loko o kekahi ʻōnaehana ea a i ʻole ea. ʻO kā lākou hana nui ka wehe ʻana i nā mea ʻino a me nā mea haumia mai ka lewa, e hāʻawi ana i ka ea maʻemaʻe no ka hanu ʻana a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ea o loko. ʻO ke kumumanaʻo e hana ai nā kānana ea e pili ana i ka manaʻo maʻalahi o ka kānana ʻana i ka lepo a me nā mea ʻē aʻe mai ka lewa i kona hele ʻana i ka kānana.

Hana nā kānana ea ma ka hoʻohana ʻana i kahi media, hiki ke hana ʻia me nā ʻano mea like ʻole, e pahele i ka lepo, pollen, uahi, a me nā mea ʻē aʻe e hiki ke hōʻeha i ke olakino kanaka. I ka holo ʻana o ka ea ma ka kānana, hopu ka media i kēia mau ʻāpana, e pale ana iā lākou mai ka hele ʻana a kaʻahele i ka lewa. I ka wā lōʻihi, e hoʻopaʻa ʻia ka media kānana me nā ʻāpana, e hōʻemi ana i kona pono a me ka hopena i ka emi ʻana o ka maikaʻi o ka ea o loko. No laila, he mea nui e hoʻololi mau a hoʻomaʻemaʻe paha i nā kānana ea e mālama i ko lākou pono.

Hoʻohana nā ʻano kānana ea like ʻole i nā ʻano a me nā mea hana e kānana i ka lepo a me nā mea ʻē aʻe. ʻO kekahi o nā mea kānana ea i hoʻohana pinepine ʻia me nā kānana HEPA, nā kānana electrostatic, a me nā kānana kalapona i hoʻāla ʻia. Hana ʻia nā kānana HEPA me kahi ʻupena paʻa o nā fiber e hiki ke hopu i nā ʻāpana liʻiliʻi loa, aʻo nā kānana electrostatic e hoʻohana i ka uila static e huki a paʻa i nā ʻāpana. Hoʻolālā ʻia nā kānana kalapona i hoʻāla ʻia no ka wehe ʻana i nā mea ʻala a me nā mea hoʻohuihui kūlohelohe mai ka lewa. He mea nui e koho i ke ʻano pono o ka kānana ea no kāu mau pono kikoʻī a no ka hōʻoia ʻana ua kūpono ia i kāu ʻōnaehana ea a i ʻole ea.

Ma waho aʻe o ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ea i loko, hiki i nā kānana ea ke kōkua i ka hōʻemi ʻana i nā kumukūʻai ikehu. ʻO nā kānana ea maʻemaʻe e hiki ai ke kahe ʻana o ka ea ma o ka ʻōnaehana ventila, e hōʻemi ana i ka ukana ma ka ʻōnaehana a hoʻomaikaʻi i kona pono. 'O ia ho'i, 'a'ole pono e hana ikaika ka 'ōnaehana no ka mālama 'ana i ka mahana i makemake 'ia, e ho'emi 'ia nā bila ikehu.

ʻO ka holoʻokoʻa, he mea nui nā kānana ea i ka mālama ʻana i ka maikaʻi o ka ea o loko a me ka hoʻoikaika ʻana i ke olakino maikaʻi. Ma ka hoʻomaopopo ʻana i ke kumumanaʻo o ka ea kānana kānana lepo, hiki iā ʻoe ke koho i ke ʻano kūpono o ka kānana ea no kāu mau pono a e hōʻoia i ka hana maikaʻi ʻana e hoʻomaʻemaʻe i ka ea āu e hanu ai.
