Ma waena o kāu ʻoihana pākaukau 9-a-5, ʻo ka hola a i ʻole ʻoe e hoʻopau i ka hao ma ke keʻena hauʻoli, a me kāu mau pāʻani Netflix i ka pō a pau, ʻaʻole ia he mea kupanaha ke hoʻolilo ʻoe ma kahi o 90 pakeneka o kou manawa i loko o ka hale. ʻO ke kumu i ka maʻi coronavirus a me nā kauoha o ka noho ʻana ma hope o ka home, a ʻo ka manawa hope loa āu i holoholo ai i ka honua i waho — ʻoiai inā he hele wāwae wale nō i ka hale kūʻai — ʻekolu paha mau lā i hala.

Me kēlā mau manawa ʻē aʻe āu i hoʻolilo ai ma kou hale haʻahaʻa, ua ʻohi paha ʻoe i ka manaʻo e hoʻololi iā ia i wahi ola olakino, e hoʻomaka me ke kūʻai ʻana i nā mea kanu hoʻomaʻemaʻe ea. Ma hope o nā mea a pau, hiki ke piʻi ʻelua a ʻelima mau manawa ke kiʻekiʻe o nā mea haumia i loko o ka hale ma mua o waho, mahalo i nā lako hoʻomaʻemaʻe, pena, a me nā mea hana i hoʻohana ʻia i kou hale, e like me ka Environmental Protection Agency. A ʻo kēia mau mea hoʻoheheʻe kūlohelohe (VOC, aka, nā kinoea i hoʻokuʻu ʻia mai kēia mau huahana hale a me nā mea hou aku) hiki ke alakaʻi i nā hopena olakino maikaʻi ʻole, e like me ka huhū o ka maka, ka ihu, a me ka puʻu; ʻeha ke poʻo a me ka nausea; a me ka hōʻino o ke ake, i waena o nā mea ʻē aʻe, no ka EPA.

Akā, aia kēlā pā hale e noho ana ma kāu windowsill a i ʻole ka nahesa ma ka papa ʻaina ma hope o kou wahi moe e hana ana i kekahi mea e kōkua ai i ke kūlana?

Minamina, ʻoiai inā like kou home ma ka ʻaoʻao Discover's Instagram, ʻaʻole ia he ea e maʻemaʻe e like me ka oxygen ma waho o kahi pahu. "ʻO ka manaʻo kuhihewa loa ʻo ia ka hoʻomaʻemaʻe ʻana o nā mea kanu i ka ea-ʻaʻole lākou," wahi a Michael Dixon, ka luna o ka Controlled Environment Systems Research Facility ma ke Kulanui o Guelph ma ke kūkulu hema o Ontario, Kanada. "He mea liʻiliʻi loa ka hana ʻana i nā home ma ka lewa o ka lewa o kahi e komo ai lākou, a ʻoi aku paha ka nui o kā lākou hopena ma muli o ka maikaʻi o ko lākou kūlana maikaʻi."

ʻO ka ʻoiaʻiʻo, he loiloi 2019 o 12 i paʻi ʻia i nā noiʻi e pili ana i nā mea kanu potated ma nā VOC airborne i ʻike wale ʻia. Paʻi 'ia ma ka Nūpepa o Exposure Science and Environmental Epidemiology, ua ʻike ʻia ka loiloi i ka hoʻololi ʻana o ka ea, a i ʻole ka wehe ʻana i nā puka aniani a i ʻole ka hoʻohana ʻana i nā ʻōnaehana ea, hoʻemi i ka nui o nā VOC ma mua o ka hiki i nā mea kanu ke lawe iā lākou mai ka lewa. ʻO ia ka mea e pono ai ʻoe ma kahi o 100 a 1000 mau mea kanu i kēlā me kēia mika mika (ma kahi o 10 kapuaʻi kuea) o ka papahele e hemo ai nā VOC e like me ka wehe ʻana o ka puka o kāu puka lumi. Inā makemake ʻoe e noho maoli i kou hale, ʻaʻole kūpono kēlā.

Ma hope o ka Myth

No laila, pehea ka manaʻo kuhihewa e hoʻohuli ai kekahi mau mea kanu i kou home i kahi oasis hou? Ua hoʻomaka hou ia i ka hopena o nā 1980s me ka ʻepekema NASA ʻo Bill Wolverton, i ʻōlelo ʻo Dixon, nāna i kākau i kahi noi ma 2011 e pili ana i ke kumuhana i paʻi ʻia ma. Biotechnology piha. I mea e ʻike ai i nā mea kanu i hana maikaʻi loa i ka kānana ʻana i nā mea haumia ʻē aʻe, ua hoʻāʻo ʻo Wolverton i kahi kakini hale kanu maʻamau - e like me ka gerbera daisy a me ka pama ʻohe - i ko lākou hiki ke hoʻoneʻe i nā mea ʻawaʻawa o ka hale mai kahi keʻena i hoʻopaʻa ʻia he 30-iniha a 30-iniha. , e like me ka NASA. Ma hope o 24 mau hola, ua ʻike ʻo Wolverton ua lawe maikaʻi nā mea kanu i 10 a 90 paha pākēneka o nā mea hoʻohaumia, e like me formaldehyde, benzene, a me trichlorethylene, i ka lewa. (E pili ana: Hoʻopilikia ka maikaʻi o ka ea i kāu hoʻomaʻamaʻa [a me kou olakino] ma mua o kou manaʻo)

ʻO ka pilikia me ka noiʻi: Ua hoʻokau ʻo Wolverton i nā mea kanu i ka nui o nā mea haumia 10 a 100 mau manawa ʻoi aku ka nui ma mua o kāu e ʻike maʻamau i ka ea maikaʻi ʻole o loko, a waiho ʻia lākou i loko o nā keʻena liʻiliʻi, wahi a Dixon. No ka loaʻa ʻana o nā hopena like, ua helu ʻo Wolverton e pono ʻoe e loaʻa ma kahi o 70 mau mea kanu spider i loko o kahi home 1800-square-foot hou. Unuhi: ʻaʻole pili nā hopena i kahi hoʻonohonoho honua maoli e like me kāu condo mid-size.

I kekahi mau hihia, hiki i kāu kūlana Mom Mom ke hana i kou ʻano maikaʻi o ka lewa. Hiki i ka lepo potting ke kumu o nā mea haumia i ka lewa, ʻoiai inā ʻoe ma luna o ka wai a hoʻohana paha i ka mea momona nui, wahi a Dixon. Hiki i ka lepo pulu ke hoʻonui i ka ulu ʻana o nā microorganism i hiki ke hoʻāla i nā maʻi āpau i kekahi poʻe, a ʻo nā paʻakai o ka nui o ka momona i hiki ke hoʻolei i ka lewa, hoʻohui ʻo ia.

Loaʻa i nā mea kanu hoʻomaʻemaʻe ea *kekahi* hopena?

E noʻonoʻo hou i kāu papa biology o ke kula kiʻekiʻe, a loaʻa iā ʻoe kahi ʻike kūpaʻa o ka mea a kāu mea kanu hoʻomaʻemaʻe lewa e hiki ai * * maoli * hana: Lawe i ka carbon dioxide a hāʻawi i ka oxygen ma o photosynthesis, wahi a Dixon. Loaʻa i nā home houseplants nā ala metabolic (nā hopena kemika i nā hunaola e kūkulu a wāwahi i nā moleola no nā kaʻina hana cellular) e hoʻohana ai i ka carbon dioxide, akā ʻaʻohe lawa o nā mea i lawe i nā mea hoʻoweliweli weliweli i loaʻa i ka ea maikaʻi ʻole e hana i ka hopena koʻikoʻi, wehewehe ʻo ia. (Ma ka liʻiliʻi e mālama i kahi māla i loko e hāʻawi iā ʻoe i kahi hua hou.)

ʻOiai kēlā manawa, ʻaʻole hoʻomaʻemaʻe lewa nā mīkini home, CO2-busting machine. Ma muli o ka hapa haʻahaʻa o nā wahi i loko o ka liʻiliʻi i nā pae māmā, hana mau nā mea kanu i ka manawa ke kūlike ka helu o ka hanu (lawe ʻana i ka carbon dioxide a me ka hoʻokuʻu ʻana i ka oxygen a me kekahi CO2) me ka photosynthesis, wahi a Dixon. I kēia manawa, ke lawe nei kahi mea kanu i ka nui like o CO2 mai ka lewa e like me kāna hana ʻana. ʻO ka hopena, "ʻo ka manaʻo o nā mea kanu potted he mea pāʻani nui i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka lewa o kahi lumi o loko," wahi āna.

Akā, ʻo nā ʻano hoʻomaʻemaʻe lewa o kekahi mau mea kanu ʻaʻole ia he hoax piha. I kekahi loa nā kūlana kūikawā, hiki i nā VOC ke hana i meaʻai no nā kaiāulu microbes (re: bacteria and fungi) i loko o ke aʻa o ka mea kanu, e hana ana i kahi "biofilter" e hōʻemi ai i nā mea haumia i ka lewa. Akā naʻe, ʻaʻole kēia he mea hiki iā ʻoe ke hoʻokō me kāu mea kanu pothos, wahi a Dixon. No ka poʻe hoʻomaka, ua hoʻonohonoho ʻia kēia mau biofilters o nā mea kanu e uhi i nā paia āpau a ʻekolu a ʻehā mau papa kiʻekiʻe ke kiʻekiʻe.

ʻO kēia mau pā nui piha i nā mea kanu he porous a he wai kaʻapuni ma o lākou e hana i kahi kūlana maikaʻi loa no nā microbes e ola hauʻoli, i kapa ʻia ʻo biofilm. ʻO nā mea pā i loko o ka ʻōnaehana huki i ka ea o ka lumi ma ka lepo, a hoʻoheheʻe kekahi VOC i loko o ka biofilm, wahi a Dixon. Ke hana nā mea kanu i ka photosynthesis a me ka hoʻokahe ʻana i nā waiʻaleʻa i ke aʻa, e ʻai ana nā kaiāulu microbial e noho ana i loko o ka biofilm-me nā mea haumia i omo ʻia i loko, wehewehe ʻo ia. "ʻO nā meaola maʻalahi a mākou e launa pū ai me nā ea maikaʻi ʻole i loko o ka ʻaoʻao kahi ʻano meaʻai māmā [no nā microbes]," wahi a Dixon. "ʻAʻole lawa ka kiʻekiʻe o ka [VOC] i mea e kākoʻo piha ai i ka nui microbial-no laila hana nā mea kanu [ma o ka photosynthesis]."

ʻO ka hoʻāʻo ʻana e DIY i kāu biofilter ponoʻī i loko o kahi mea kanu i loko o ka ipuhao he "paʻakikī loa," ma muli o kēlā mau kukui haʻahaʻa i loaʻa i nā hale, wahi a Dixon. ʻAʻole e haʻi ʻia, paʻakikī nui lākou e mālama a ʻaʻole loaʻa no ka hoʻohana home i kēia manawa. Akā,ʻaʻoleʻoe i SOL loa inā makemakeʻoe e hoʻomaʻemaʻe i kou ea i loko: "Ma keʻano maoli, e wehe wale i ka puka makani, e hoʻonui ai i ka hoʻololi kinoea me waho," wahi āna. (A inā muggy loa kou home, e hoʻohuli i kekahi o kēia mau dehumidifiers kiʻekiʻe loa.)

A ʻoiai ʻaʻole hiki i kāu mea kanu hoʻomaʻemaʻe lewa ke hana i ka hana āu i manaʻo ai, ʻo ka liʻiliʻi ma kahi o ka greenery e hiki ke kōkua iā ʻoe e hana hou aʻe a hoʻemi i kou mau koʻikoʻi, e like me ka noiʻi ʻana mai ke Kulanui ʻo Wakinekona State. Eia kekahi, ʻo ka mālama ʻana iā lākou he hana #adulting maikaʻi ma mua o kou hāpai ʻana i kahi ʻīlio, ʻeā?
