Quoted from Kompas.com, this research was published by Centers of Disease Control and Prevention (CDC).
Air purifier HEPA filters are known to reduce the risk of exposure to indoor COVID-19 simulated aerosols by up to 65 percent.
If coupled with the use of masks in closed spaces, the risk can be reduced by 90 percent.
High efficiency particulate air (HEPA) filter is an air filter in the form of folds which in theory can filter dust, powder, mold, bacteria, and air particles measuring 0.3 microns to 99.97 percent.
HEPA filters are useful for filtering air and cleaning surfaces from dust and particles that trigger allergies or asthma.
It is known that allergenic particles, such as dust, pollen, and others, are more than 0.3 microns in size so they can be filtered in the HEPA filter.
So, using this filter at home can help relieve allergy and asthma symptoms.
Now, new research says air purifier With a HEPA filter, you can reduce the transmission of COVID-19.
Covid-19 is a disease caused by the SARS-CoV-2 virus that spreads through droplets and aerosols when a person breathes, coughs, talks, and sings.
This research was conducted by simulating the spread of the SARS-CoV-2 virus indoors by adding an air purifier with a HEPA filter.
The research was conducted in a meeting room and carried out three kinds of simulations.
The result is that air purifiers with HEPA filters can reduce indoor aerosol exposure by up to 65 percent without the use of masks.
Meanwhile, the use of masks alone in a room without an air purifier can protect against aerosol exposure by up to 72 percent.
By combining air purifier With HEPA filters and the use of masks, the risk of Covid-19 transmission can be reduced by up to 90 percent.
