MAC500s reduces airborne
virus effectively
The difference between droplet and airborne transmission
Droplet transmission
Coughs and sneezes can spread
droplets of saliva and mucus
Airborne transmission
Tiny particles, possibly produced
by talking, are suspended in the
air for longer and travel further.
Less than
5 microns
More than
5 microns
Viruses in aerosols (smaller than 100 μm) can remain suspended in air for many seconds to
hours, like smoke, and be inhaled.
They are highly concentrated near an infected person, so they can infect people most easily
in close proximity.
But aerosols containing infectious virus can also travel more than 2 m and accumulate in
poorly ventilated indoor air, leading to superspreading events.

In May 2021, the Centers for Disease Control ocially recognized that SARS-CoV-2—the virus that causes
COVID-19—is airborne, meaning it is highly transmissible through the air. It took more than a year into
pandemic and even now very little is done to mitigate airborne transmission risk. Fighting airborne virus is the
key to stop the virus from spreading.
ASHRAE: “Airborne transmission of SARS-CoV-2 is signicant and should be controlled.”*
CDC: “The principal mode by which people are infected with SARS-CoV-2 is throughexposure to respiratory
droplets carrying infectious virus.”**

Cough: Travel up to 5,8 m (19 feet)
3,000 droplets
Sneeze: Travel up to 7,9 m (26 feet)
40,000 droplets”
Aerosols created by a sneeze, cough,
singing, talking etc. can contain virus and
can linger in the air for several hours.
The aerosols emitted from the human
body are hotter than ambient air which
makes them rise in normal room
temperature.
• Aerosol can travel far longer than
2 meter (6 feet).
• Aerosols can contain virus.
• Aerosols are invisible to the human eye.
• Aerosols transmitted from a human
tend to rise in the room as these
aerosols are warmer than ambient air.
