Raws li kev tshawb fawb luam tawm nyob rau hauv phau ntawv Journal Clinical and Translational Allergy, portable air filtration units with enough clean air delivery rates can effectively remove mites, cat and dog allergen, and particulate matter from indoor ambient air.
Cov kws tshawb fawb hu nws qhov kev kawm dav dav tshaj plaws, tsom mus rau kev ua haujlwm ntawm huab cua kom pom tseeb rau ntau yam ntawm huab cua hauv chav pw.
"Ob xyoos ua ntej txoj kev tshawb no, ntau tus kws tshawb fawb hauv Tebchaws Europe thiab kuv tau muaj lub rooj sib tham tshawb fawb txog huab cua zoo thiab kev ua xua," said Jeroen Buters, PharmD, toxicologist, tus thawj coj ntawm Lub Chaw Tiv Thaiv Kev Tiv Thaiv thiab Ib puag ncig, thiab tus tswv cuab ntawm German Center Munich. Kev Lag Luam Lub Chaw Tshawb Fawb Lub ntsws ntawm University thiab Helmholtz Center hais rau Healio.
Cov kws tshawb fawb tau tshuaj xyuas Dermatophagoides pteronyssinus Der p 1 thiab Dermatophagoides farinaeDer f 1 tsev plua plav mite allergen, Fel d 1 miv allergen thiab Can f 1 aub allergen, tag nrho cov no tuaj yeem kuaj pom nyob rau hauv cov khoom hauv huab cua (PM)
"Txhua tus neeg xav tias Dermatophagoides pteronyssinus yog cov kab mob ua xua loj hauv tsev neeg.Tsis yog - tsawg kawg tsis nyob hauv Munich, thiab tej zaum tsis yog lwm qhov.Nyob ntawd nws yog Dermatophagoides farinae, lwm yam kab ntsig zoo sib xws.Yuav luag tag nrho cov neeg mob tau kho nrog kev rho tawm ntawm D pteronyssinus.Vim tias qhov zoo sib xws ntawm lawv, qhov no yog qhov ua tau zoo, "Butters hais.
“Tsis tas li ntawd, txhua tus mite nyob txawv, yog li koj paub zoo dua qhov koj tab tom tham txog.Qhov tseeb, muaj ntau tus neeg hauv Munich uas nkag siab rau D. farina dua D. pteronyssinus, "nws hais ntxiv..
Cov neeg tshawb xyuas tau tswj xyuas thiab kev cuam tshuam hauv txhua tsev neeg ntawm 4 lub lis piam ib ntus.Thaum mus ntsib kev cuam tshuam, lawv sawv cev rau cov xwm txheej cuam tshuam los ntawm kev co hauv ncoo rau 30 vib nas this, npog lub txaj rau 30 vib nas this, thiab daim ntawv txaj rau 60 vib nas this.
Tsis tas li ntawd, cov kws tshawb fawb tau ntsuas Der f 1 concentrations nyob rau hauv cov chav nyob ntawm plaub lub tsev thiab pom tias qhov nruab nrab concentration yog 63.2% qis dua cov nyob hauv chav pw.
“Ib txoj kev tshawb fawb Australian pom muaj cov tshuaj allergens nyob rau hauv lub chav sofa.Peb tsis tau.Peb pom nws hauv txaj.Tej zaum nws yog Australian-European gradient, "Butters hais.
Tam sim ntawd tom qab txhua qhov kev tshwm sim, cov kws tshawb fawb tau qhib lub tshuab lim dej thiab khiav mus rau 1 teev.Qhov txheej txheem no tau rov ua plaub zaug thaum txhua qhov kev mus ntsib, rau tag nrho 4 teev ntawm kev kuaj hauv ib tsev neeg.Cov kws tshawb fawb tom qab ntawd tshuaj xyuas cov khoom uas tau sau hauv lub lim.
Txawm hais tias tsuas yog 3 tsev neeg muaj miv thiab 2 tsev neeg muaj dev, 20 tsev neeg Der f 1, 4 tsev neeg Der p 1, 10 tsev neeg Can f 1 thiab 21 tsev neeg Fel d 1 tsim nyog kom muaj nuj nqis.
"Nyob rau hauv yuav luag tag nrho cov kev tshawb fawb, qee tsev neeg tsis muaj kab mob mite.Nrog rau peb txoj hauv kev zoo, peb pom muaj allergens nyob txhua qhov chaw, "Butters tau hais tias, sau tseg tias tus naj npawb ntawm cov miv allergens kuj xav tsis thoob.
Butters hais tias "Tsuas yog peb ntawm 22 tsev neeg muaj miv, tab sis miv allergens tseem muaj nyob txhua qhov chaw," Butters hais.
Tag Nrho Der f 1 hauv huab cua tau txo qis (P < .001) los ntawm huab cua pom, tab sis qhov txo qis hauv Der p 1 tsis tseem ceeb, cov kws tshawb fawb tau hais tias. Tsis tas li ntawd, qhov nruab nrab tag nrho Der f 1 tau txo los ntawm 75.2% thiab qhov nruab nrab tag nrho Der p 1 poob los ntawm 65.5%.
Huab cua pom kuj txo qis tag nrho Fel d 1 (P < .01) los ntawm qhov nruab nrab ntawm 76.6% thiab tag nrho Can f 1 (P < .01) los ntawm qhov nruab nrab ntawm 89.3%.
Thaum lub sij hawm tswj xyuas, qhov nruab nrab Can f1 yog 219 pg/m3 rau cov tsev neeg uas muaj dev thiab 22.8 pg/m3 rau cov tsev neeg tsis muaj dev. Thaum lub sij hawm mus xyuas, qhov nruab nrab Can f 1 yog 19.7 pg / m3 rau cov tsev neeg nrog dev thiab 2.6 pg / m3 rau tsev neeg tsis muaj dev.
Thaum lub sij hawm tswj xyuas, qhov nruab nrab FeI d 1 suav yog 50.7 pg/m3 rau cov tsev neeg uas muaj miv thiab 5.1 pg/m3 rau cov tsev neeg uas tsis muaj miv. Thaum lub sij hawm mus saib xyuas, cov tsev neeg uas muaj miv muaj suav 35.2 pg/m3, hos cov tsev neeg uas tsis muaj miv tau suav ntawm 0.9 pg / m3.
Feem ntau Der f 1 thiab Der p 1 tau kuaj pom hauv PMs nrog qhov dav siab dua 10 microns (PM> 10) lossis nruab nrab ntawm 2.5 thiab 10 microns (PM2.5-10).Feem ntau cov tshuaj tiv thaiv miv thiab dev kuj cuam tshuam nrog PMs ntawm qhov ntau thiab tsawg. .
Tsis tas li ntawd, Can f 1 tau txo qis thoob plaws txhua qhov PM qhov ntev nrog ntsuas qhov ua xua, nrog qhov nruab nrab ntawm 87.5% (P < .01) rau PM > 10 (P < . < .01).
Thaum cov khoom me me nrog cov tshuaj ua xua nyob hauv huab cua ntev dua thiab muaj feem yuav nqus tau ntau dua li cov khoom loj, huab cua pom kuj tshem tawm cov khoom me me zoo dua, tso cai rau cov kws tshawb fawb hais.Huab cua lim dhau los ua ib lub tswv yim zoo rau tshem tawm cov allergens thiab txo qhov raug.
"Kev txo cov tshuaj tsis haum yog mob taub hau, tab sis nws ua rau cov neeg muaj kev fab tshuaj zoo dua.Txoj kev no tshem tawm cov allergens yog ib qho yooj yim, "Buters hais tias, sau tseg tias txo cov miv allergens (uas nws hu ua plaub loj allergens) yog qhov nyuaj tshwj xeeb.
Nws hais tias, "Koj tuaj yeem ntxuav tus miv - hmoov zoo - lossis khiav tus miv mus," Kuv paub tsis muaj lwm txoj hauv kev los tshem tawm cov kab mob miv.Air filtration ua. "
Tom ntej no, cov kws tshawb fawb yuav tshuaj xyuas seb cov neeg ua xua puas tuaj yeem pw tsaug zog zoo dua nrog lub tshuab lim cua.
