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.
Umuryango wubuvuzi nturamenya neza umubare wibikoresho byoza ikirere bifasha guhagarika ikwirakwizwa rya coronavirus. Ntagushidikanya ko bashobora gufasha ababana na allergie kandi yarakoreshejwe imyaka myinshi, ariko kuyungurura ibisobanuro bito bito birimo COVID-19 biragoye cyane. Nta muganga uvuga ko ibikoresho byogeza ikirere bishobora gutwara iki kibazo. Abahanga barasaba kwambara masike no kwitandukanya na societe nkumurongo wambere wo kwirwanaho. Biroroshye cyane kwemeza ko COVID-19 ibice bitigera byinjira mu kirere kuruta kuyungurura nyuma yo gutatana. Nyamara, ibikoresho byinshi byo kweza ikirere ntabwo byangije iki kibazo.
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.
Gusa ndashaka kuguha igitekerezo. Mu cyumba cyo gukoreramo, umwuka uhinduka buri minota itatu kugeza kuri itandatu, mugihe mu nyubako y'ibiro, ihinduka inshuro nyinshi mu isaha.
“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.
Mubyukuri, biragoye kwiga uburyo bwo gufungura idirishya kugirango uhindure umwuka. Umwuka uhumeka mumwanya wimbere biragoye kubigereranya cyangwa no guhanura. Icyitegererezo cyiza cyo kubaka kwisi biragoye gukemura ikibazo cyo gufungura idirishya kuko sisitemu yo mu kirere iragoye cyane. Icy'ingenzi, gufungura Windows bishobora kuba byiza nkibisukura ikirere, cyangwa bikarushaho gukora neza. Gukoresha umwuka wo mu nzu ushobora kuba urimo COVID-19 hamwe n’umwuka wo hanze utagira virusi bizagabanya ubukana bwa virusi mu kirere, bityo bigabanye amahirwe yo kwandura. Abashakashatsi baracyafite ikibazo cyo kumenya umubare uhumeka nubwoko bwiza. Ntabwo byumvikanyweho bihagije mubuvuzi.
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.”
Kutagira ibisubizo byose ntabwo ari byiza, ariko nibyiza kuruta kwitwaza ko ufite ibisubizo. Kuba inyangamugayo kubishobora cyangwa bidashobora gukora birashobora gufasha abantu guhitamo neza kubijyanye no kwirinda umutekano. Kimwe n'imitwe myinshi ijyanye no gutunganya ikirere, imitwe ntabwo. Nibyiza, barashobora kwibeshya kubwumutekano. Mugihe kibi cyane, ionizers, generator ya plasma hamwe nubushyuhe bwa electrostatike birashobora guteza ingaruka nziza. Ibi bikoresho byishyuza ibice kugirango bifatanye hejuru aho kureremba mu kirere, bityo bikabyara ozone nkibicuruzwa.
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.
Imyitozo myiza yumuyaga mwiza uzenguruka guhumeka. Mu biro bigezweho, gufungura Windows ntibishoboka kubwimpamvu nyinshi. Mubisanzwe, Windows ntishobora gufungurwa na gato. Muri iki kibazo, urashobora kwemeza ikoreshwa ryibikoresho byo mu kirere byujuje ubuziranenge. Kubera ko filozisiyo yo mu kirere idashingiye kuri ozone idatanga ingaruka mbi, gusa ibibi byibikoresho byungurura ikirere byigiciro ni urusaku. Igipimo cyiza cyo kohereza ikirere (CADR) cyigikoresho kirakubwira byinshi mubikorwa byacyo. Uru rutonde ruzirikana imikorere ya filteri nimbaraga zabafana kugirango bamenye umubare wumwuka unyura muyungurura. Hejuru ya CADR, nini umwanya wo kweza. Kugura ibikoresho byiza ni ukumenya gusa ingano yicyumba. Wibuke, uko igikoresho kinini, niko umufana azenguruka ikirere, kandi ijwi rikazamuka. Mubiro byo mu biro, urusaku rwinshi rugomba gutekerezwa. Igiciro cyogusukura ikirere cyiza cya HEPA gitangirira hafi $ 200, kandi igiciro cyacyo cyiyongera uko urwego rwa CADR rwiyongera. Abantu bamwe ndetse biyubakira ibyuma bisukura ikirere bahambira akayunguruzo ka MERV kubakunzi ba bokisi munsi y $ 30.
Iyo ukorana nibikoresho bisabwa mubuvuzi, burigihe ni ngombwa gutandukanya ukuri nimpimbano no kungukirwa no kwamamaza. Abakora ibicuruzwa bizeye ko bazunguka cyane kubikoresho bikenerwa na COVID-19 byoroheje isoko byuzuza isoko ibikoresho byogeza ikirere byoroshye. Abahanga bemeza ko ibikoresho byo mu rwego rwo hejuru rwose bitazangirika. Birashoboka rwose gukora ibyuma bisukura ikirere ukoresheje amagana cyangwa ibihumbi byamadorari mubikoresho byoza ikirere, ariko ntidushobora kumenya umubare wabyo. Igisubizo cyiza nukwambara mask, kandi niba bishoboka, fungura idirishya.
Propmodo isobanura kandi isobanura imigendekere yubucuruzi bwimitungo itimukanwa ihuza amakuru, ubushakashatsi, ibyabaye na serivisi zamamaza.
