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.
Komunitas medis isih ora yakin pira piranti pembersih udara sing bener-bener mbantu nyegah panyebaran koronavirus. Ora ana keraguan manawa bisa nulungi penderita alergi lan wis digunakake pirang-pirang taun, nanging nyaring rincian partikel cilik sing ngemot COVID-19 luwih angel. Ora ana dhokter sing ujar manawa peralatan pembersih udara portabel bisa ngatasi masalah iki. Para ahli nyaranake nganggo topeng lan tetep adoh saka masyarakat minangka garis pertahanan pertama. Luwih gampang kanggo mesthekake yen partikel COVID-19 ora tau mlebu udhara tinimbang nyaring sawise disebar. Nanging, umume peralatan pembersih udara ora ngrusak kahanan kasebut.
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.
Mung arep menehi idea. Ing kamar operasi, udhara diganti saben telung nganti enem menit, nalika ing gedung kantor diganti kaping pirang-pirang saben jam.
“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.
Kanggo tepat, angel sinau carane mbukak jendhela kanggo ngganti ventilasi. Aliran udara ing njero ruangan angel dimodelake utawa malah diprediksi. Model bangunan paling apik ing donya angel kanggo ngatasi masalah mbukak jendhela amarga sistem aliran udara rumit banget. Ngencerake hawa njero ruangan sing bisa ngemot COVID-19 kanthi hawa ruangan sing bebas virus bakal nyuda konsentrasi virus ing udhara, saengga nyuda kemungkinan infeksi. Peneliti isih berjuang kanggo ngerteni sepira ventilasi lan jinis sing paling apik. Ana mung ora cukup konsensus ing komunitas medis.
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.”
Ora duwe kabeh jawaban ora becik, nanging luwih becik tinimbang pura-pura duwe jawaban. Jujur babagan apa sing bisa ditindakake utawa ora bisa mbantu wong nggawe pilihan pribadi sing luwih apik babagan carane tetep aman. Kaya akeh kepala sing ana hubungane karo pembersih udara, kepala ora. Ing paling apik, padha bisa mistaken kanggo rasa aman. Ing kasus sing paling ala, ionizer, generator plasma lan precipitator elektrostatik bisa ngasilake bebaya positif. Piranti kasebut ngisi partikel supaya tetep ing permukaan tinimbang ngambang ing udhara, saéngga ngasilake ozon minangka produk sampingan.
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.
Praktek paling apik kanggo hawa resik revolve watara ventilasi. Ing kantor modern, mbukak jendhela bisa uga ora bisa ditindakake amarga akeh alasan. Biasane, jendhela ora bisa dibukak kabeh. Ing kasus iki, sampeyan bisa mesthekake nggunakake piranti filtrasi udhara kualitas dhuwur. Wiwit filtrasi udara sing ora adhedhasar ozon ora ngasilake efek samping sing mbebayani, mung kekurangan peralatan filtrasi udara portabel yaiku biaya lan gangguan. Tingkat transfer udhara resik (CADR) piranti nuduhake paling efektif. Rating iki njupuk menyang akun efficiency saka Filter lan daya saka penggemar kanggo nemtokake carane akeh online mili liwat Filter. Sing luwih dhuwur CADR, luwih gedhe ruang pemurnian. Tuku peralatan sing tepat mung kanggo nemtokake ukuran kamar sing pas. Elinga, piranti sing luwih gedhe, kipas sing luwih kuat bakal ngedhunake hawa, lan swara sing luwih banter. Ing lingkungan kantor, akeh gangguan kudu dianggep. Rega pembersih udara HEPA sing berkualitas tinggi diwiwiti sekitar $200, lan regane mundhak nalika tingkat CADR mundhak. Sawetara wong malah nggawe pembersih udara dhewe kanthi naleni saringan MERV menyang penggemar kothak kanthi rega kurang saka $30.
Nalika ngatasi peralatan kanthi syarat medis, mesthi penting kanggo misahake kasunyatan saka fiksi lan entuk manfaat saka marketing. Produsen produk sing ngarep-arep entuk bathi saka panjaluk gedhe kanggo peralatan mitigasi COVID-19 wis mbanjiri pasar kanthi peralatan pembersih udara portabel. Para ahli percaya manawa peralatan sing berkualitas tinggi mesthi ora bakal cilaka. Pancen bisa nggawe pembersih udara kanthi mbuwang atusan utawa malah ewonan dolar kanggo peralatan pembersih udara, nanging kita ora bakal ngerti jumlahe. Wangsulan sing luwih apik yaiku nganggo topeng, lan yen bisa, bukak jendhela.
