According to Francesca Dominici, a Harvard biostatistics professor said: “If you’re getting COVID-19, and you’ve been breathing polluted air, it’s really like putting gasoline on the fire.”
A study published in Environmental Pollution, researchers from Aarhus University in Denmark and the University of Siena in Italy found a clear correlation between air pollution and death rates from COVID-19 in Italy. The authors of the study in Environmental Pollution found a significant variation in the lethality of the virus, depending upon geography, with northern regions such as Lombardy and Emilia-Romagna seeing a lethality rate around 12%, while the rest of Italy had a lethality rate around 4.5%. Meanwhile, new research published in the journal Science of the Total Environment shows that almost 80% of deaths across four countries – Italy, Spain, France, and Germany – were in the most polluted regions.
As COVID-19 attacks through respiratory tracts and targets the lungs, it makes sense that death rates would be higher in places with poor air quality. Though higher air pollution is typically associated with more densely populated cities, air pollution is everywhere to varying degrees. Pollutant particles, known as PM2.5, penetrate deep into the human body, increasing complications in coronavirus patients. Nitrogen dioxide, a pollutant produced by diesel vehicles, has long been linked to lung damage, and long-term exposure to the pollutant may be a key contributor in COVID-19 fatality.
Based on the above research, we should do everything we can to keep our immediate air space as clean as possible – especially indoors. Use an indoor air purification system, keep plants around you and open those windows to get good circulation. These are all good tips to keep your indoor air clean.
Let’s take the question a step further:
We shouldn’t just care about its virus-killing capability, e.g. whether it has a UV, ozone, or ionizers inside. It is also important to consider its clean air delivery rate (CADR), a key parameter for air purifiers.
CADR indicates how quickly an air purifier could remove the pollution particles in the air.
Airdog air purifiers actively kill viruses by using high voltage inside. This is different from the traditional HEPA filter system of passive filtration.
Airdog products offer very high CADR for different room sizes. Our X5 model has a CADR of 220 CFM, which could circulate a 450 sq. ft. room four times in an hour. The X8 model has a CADR of 500 CFM, which could circulate 1000 sq. ft. room four times in an hour.
Another important factor is that the Airdog TPA technology collects particles down to 14.6 nm, which is beyond the traditional HEPA filters capture the scope of 300 nm (or written as 0.3 microns).
Since viruses are parasitic and want to attach to a carrier microbe, it is important to reduce airborne particles, especially those ultrafine particles, to help eliminate the virus carriers and thus reduce virus spreading.
Airdog air purifiers can help clean your indoor air at a microscopic level and thus add a layer of deterrence against viruses.
Stay safe and stay strong. We are all in this fight together!
