In the era of deadly airborne viruses, air purification equipment has now shown various shapes and sizes. At last month’s Consumer Electronics Show CES, the company introduced a new portable air filter device for your bedside, cup holder, table top, meeting room, and even hanging around your neck. Although each of these devices can purify the air, the problem is that none of them can ventilate. Science increasingly shows that if you are serious about stopping the spread of the coronavirus, masks, social distancing and opening windows may do more than expensive electronic purification equipment.
Most air purifier designs use the same basic method. There is a filter and fan. The fan draws in and circulates air through the filter. The filters in these types of equipment are usually made of paper, fiber (usually glass fiber) or some type of net, which allows it to remove contaminants such as dust and pollen well, but cannot remove gas or less. particle. It is important to remember that the work efficiency claimed by the air purifier manufacturer is accurate after laboratory testing, but it is almost impossible to recreate the specific laboratory conditions. The location, installation, flow rate and running time of the purifier will greatly affect its working effect. Ventilation is usually a big problem. After the air is “purified”, the fan circulates it out, but the air is not ventilated to other areas of the space. Therefore, air purifiers often repeatedly purify the same air in their vicinity. The smaller the device, the greater the basic problem.
Bulshada caafimaadku wali ma hubo inta aaladaha sifaynta hawada ay dhab ahaantii gacan ka geystaan joojinta faafitaanka coronavirus. Shaki kuma jiro inay caawin karaan dadka xasaasiyadda qaba oo la isticmaalayey sannado badan, laakiin sifaynta faahfaahinta walxaha yaryar ee ay ku jiraan COVID-19 aad ayey u adag tahay. Ma jiro dhakhtar sheegay in qalabka sifaynta hawada ee la qaadi karo uu xallin karo dhibaatadan. Khubaradu waxay ku talinayaan xidhashada waji-xidhka iyo ka fogaanshaha bulshada oo ah safka koowaad ee difaaca. Aad bay uga sahlan tahay in la hubiyo in walxaha COVID-19 aysan waligood hawada gelin intii la sifeyn lahaa ka dib marka ay kala firdhaan. Si kastaba ha ahaatee, inta badan qalabka sifaynta hawada ma aysan waxyeeleynin xaaladdan.
More useful than filtration is to increase ventilation. Studies have shown that keeping the air “fresh” is one of the best ways to stop diffusion. Known as air change, the rate at which air is completely replaced in a space is a key indicator of the level of symbiosis risk. The more changes in the air, the better. Mayo Clinic professor and researcher Dr. Mark Ereth explained in our recent “Flexible Workplace” report how much air is needed to pass through a room to help eliminate ultrafine particles such as COVID-19. In an office building, there are several times an hour every three to six minutes,” he said. There is evidence that, with the aid of a central ventilation system, air purifiers increase the air exchange rate or volume. But open the windows is also like this.
Kaliya waxaan rabaa inaan fikrad ku siiyo. Qolka qalliinka, hawadu waa la beddelaa saddex ilaa lix daqiiqo, halka dhismaha xafiiska, la beddelo dhowr jeer saacaddii.
“The most important thing to consider when buying an air filter is whether the space you want to use in it already has good ventilation-then the air filter won’t increase too much,” Dr. Shelly Miller, an environmental expert, Colorado An engineer at the University of Boulder told Webmd that his research focuses on the spread of airborne diseases.
Si loo saxo, way adag tahay in la barto sida loo furo daaqad si loo beddelo hawo-qaadista. Socodka hawada ee meel gudaha ah way adag tahay in la qaabeeyo ama xitaa la saadaaliyo. Qaabka dhismaha ugu fiican aduunka waa ay adagtahay in la xaliyo dhibaatada furitaanka daaqada sababtoo ah nidaamka hawadu aad ayuu u dhib badan yahay Ku qasidda hawada gudaha ee laga yaabo inay ku jirto COVID-19 hawo bannaanka oo aan fayras lahayn waxay yaraynaysaa isku-ururinta fayrasku ku jiro hawada, iyadoo hoos u dhigaysa fursadda caabuqa. Cilmi-baadhayaashu waxay weli ku dhibtoonayaan inay ogaadaan inta hawo-qaadashada ah iyo nooca ugu fiican. Ma jiro wax la isku raacsan yahay oo ku filan bulshada caafimaadka.
Columbia University virologist Angela Rasmussen told Vox: “There is no perfect “safe” level of ventilation because we actually don’t know what “safe” is because we don’t know how much exposure will cause spread.”
Jawaabaha oo dhan la'aantu maaha mid ku habboon, laakiin way ka fiican tahay inaad iska dhigto inaad jawaabo hayso. Ka daacadnimada waxa laga yaabo inay shaqeeyaan ama laga yaabo inay shaqeeyaan waxay dadka ka caawin kartaa inay sameeyaan doorashooyin shakhsiyeed oo wanaagsan oo ku saabsan sidii ay ammaan ugu ahaan lahaayeen. Sida madax badan oo la xidhiidha nadiifiyeyaasha hawada, madaxyadu ma sameeyaan. Sida ugu fiican, waxaa lagu khaldi karaa dareen ammaan. Xaaladda ugu xun, ionizers, koronto-dhaliyeyaasha balaasmaha iyo korantada ayaa soo saari kara khataro togan. Qalabyadani waxay dallacaan qaybo si ay dusha sare ugu dhegaan halkii ay hawada ku sabayn lahaayeen, si ay u soo saaraan ozone sida wax soo saarkooda.
ASHRAE, a professional association that specializes in setting standards for ventilation and air-conditioning, said that when using equipment that may generate large amounts of ozone (respiratory tract irritant) as a by-product of its operation, “must be extra careful.” HEPA and ASHRAE recommend avoiding the use of any air purification devices that produce ozone as a by-product of cleaning indoor air in living spaces.
Hababka ugu wanaagsan ee hawada nadiifka ah waxay ku wareegaan hawo-qaadista. Xafiiska casriga ah, furitaanka daaqadaha ayaa laga yaabaa inaanay suurtogal ahayn sababo badan dartood. Sida caadiga ah, gabi ahaanba daaqadaha lama furi karo. Xaaladdan oo kale, waxaad xaqiijin kartaa isticmaalka qalabka sifeynta hawada tayada sare leh. Maaddaama shaandhaynta hawada aan-ozone-ku-salaysan aanay soo saarin waxyeellooyin waxyeello leh, faa'iido darrada kaliya ee qalabka sifaynta hawada ee la qaadi karo waa kharash iyo buuq. Heerka xawilaadda hawada nadiifka ah (CADR) ee qalabku wuxuu kuu sheegayaa waxtarkiisa inta badan. Qiimayntani waxay tixgalinaysaa waxtarka shaandhada iyo awooda marawaxad si loo ogaado inta hawadu ku socoto shaandhada. Markasta oo uu sareeyo CADR, waa sii weynaada booska nadiifinta. Iibsashada qalabka saxda ah waa kaliya in la go'aamiyo cabbirka qolka saxda ah. Xasuusnoow, mar kasta oo qalabku uu weynaado, ayaa marwadu ay sii xoogaysanaysaa hawada, iyo inta uu codku sii kordhin doono. Deegaanka xafiiska, buuq badan waa in la tixgeliyaa. Qiimaha nadiifiyaha hawada ee tayada sare leh ee HEPA wuxuu ka bilaabmaa qiyaastii $200, qiimihiisana wuu kordhaa marka heerka CADR uu kordho. Dadka qaarkiis xitaa waxay dhistaan hawo-sifeeye iyaga u gaar ah iyagoo ku xiraya filtarrada MERV si ay ugu xiraan taageerayaasha wax ka yar $30.
Markaad la macaamilayso qalabka shuruudaha caafimaadka, had iyo jeer waa muhiim in la kala saaro xaqiiqda iyo khayaaliga iyo in laga faa'iidaysto suuqgeyn. Soosaarayaasha badeecadaha oo rajaynaya inay ka faa'iidaystaan baahida weyn ee loo qabo qalabka yaraynta COVID-19 ayaa suuqa ku daadadiyay qalabka sifaynta hawada la qaadan karo. Khubaradu waxay rumaysan yihiin in qalabka tayada sare leh hubaal aanu waxyeello u geysan doonin. Runtii waa suurtogal in la sameeyo nadiifiyeyaasha hawada iyadoo lagu kharash gareynayo boqollaal ama xitaa kumanaan doolar qalabka sifaynta hawada, laakiin waxaa laga yaabaa inaan waligeen ogaanin inta ay le'eg tahay. Jawaabta ugu fiican waa in la xidho maaskaro, haddii ay suurtagal tahay, fur daaqadda.
