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.
Communitas medicorum adhuc non est certus quot machinas purificationis aeris adiuvant reprimendi dilatationem coronavirus. Non dubium est quin allergy laborantes adiuvent et multis annis adhibiti sunt, sed eliquare singulas particulas parvas quae COVID-19 multo difficiliores sunt. Nullus medicus dicit apparatum purificationis portatilem aere hoc problema solvere posse. Periti larvis commendant vestiti et a societate ut prima defensionis linea morantur. Facilius est ut particulae COVID-19 aerem numquam ingrediantur quam eas eliquare postquam dispersae sint. Maxime autem aer purificationis huic rei non nocuit.
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.
Iustus volo tibi dare ideam. In conclavi operante, aer mutatur singulis tribus ad sex minutas, dum in officio aedificio pluries per horam mutatur.
“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.
Difficilis esse, difficile est videre quomodo evacuatione mutare fenestram aperire. Fluxus in spatio amet, difficile est fingere vel etiam praedicere. Exemplar optimum aedificium in mundo difficile est problema aperitionis fenestrae solvere quod ratio aeris fluxus tam multiplex est. Maxime fenestrae apertae tam efficaces esse possunt quam purificatores aeris, vel etiam efficacius. Dilutatio aeris indoor quod COVID-19 contineat cum aere virus libero velit, coactionem viri in aere reducet, inde casu infectionis minuendi. Investigatores adhuc nituntur invenire quantam evacuationem et quod genus sit optimum. Consensus simpliciter non est satis in communitate medicinae.
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.”
Non omnia responsa habentia non est specimen, sed melius est quam habere responsa simulans. Esse honestum quid possit vel non operari potest adiuvare homines electiones personales melius facere quomodo in tuto manere. Sicut multa capita pertinentia ad aerem purificatorium, capita non habent. In melius, securitatis sensus falli possunt. In gravissimo casu, ionizers, plasma generantium et praecipitatores electrostaticae casus positivum producere possunt. Quae machinae particulas incurrunt ita ut in aere natantes loco superficiei haereant, inde ozonem ut byproductum producant.
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.
Exercitia optima pro aere puro circum evacuatione volvuntur. In officio moderno, fenestrae apertae multis de causis fieri non possunt. Usitas, fenestrae omnino aperiri non possunt. In hoc casu, uti potes curare GENERALIS aeris filtrationis machinas. Cum filtratio aeris non-ozone fundata non gignit effectus nociva, solum incommoda aerea filtrationis portatilis sumptus et strepitus sunt. Mundus aer translationis rate (CADR) machinae efficaciam suam maxime tibi narrat. Haec aestimatione consideratur efficientiam colum et vim ventilationis determinare quantum aer per colum fluit. Altior cadr, tanto purgatio spatii. Emptio instrumenti ius tantum est ad magnitudinem cubiculi ius determinare. Memento, majoris fabrica, ventilabrum fortius circulabit aerem, et sonus majoris erit. In officio ambitus, strepitus multum considerari debet. Pretium summus qualitas aeris mundantis HEPA in circuitu $ 200 incipit, et pretium eius augetur quantum in gradu CADR augetur. Aliqui etiam proprium aerem purificatorium construunt, filtras ad pixidem alligant MERV minus quam $30.
Cum de apparatu cum medicinis requisitis, semper refert rem fictam separare et a venalitate prodesse. Producti artifices sperantes lucrum ex ingenti postulatione COVID-19 mitigationis instrumenti mercatum inundaverunt cum apparatu aeris portatili purificationis. Periti putant apparatum GENERALE certe laedi non posse. Fieri quidem potest ut aerem purificatorium expendendo centenaria vel etiam milia dollariorum instrumento purificationis aerem efficere possit, sed numquam scire possumus quot sunt. Sed melius est personam gerere et, si fieri potest, fenestram aperi.
