According to experts, home AC units do not pose any additional risk of Covid-19 infection, especially at a time when people are isolated inside their homes with no outside contact. If people visit a centrally air conditioned mall during a pandemic, the risk of getting exposed to the coronavirus directly from an infected person is far greater than getting it from the recycled AC air. The use of air conditioners can lead to tiny droplets that contain the coronavirus being carried on the flow of air, raising the risks of infection even for people who are some distance from infected individuals. At IntellectPeritus, we have collected around 100 patent documents related to Indoor Air Sanitizers as sample report and have tried to put value added technology categories to generate specific insights quickly using our deliverable “Innovigence Corona” If you are interested in detailed or any customized report for Indoor Air Sanitizer, please feel free to write to us at sales@intellectperitus.com

2. According to experts, home AC units do not pose any additional risk of Covid-
19 infection, especially at a time when people are isolated inside their homes
with no outside contact.
However, coronavirus can spread within spaces that are centrally air
conditioned such as shopping malls and some modern apartments, especially
if an infected person is inside such spaces.
If people visit a centrally air conditioned mall during a pandemic, the risk of
getting exposed to the coronavirus directly from an infected person is far
greater than getting it from the recycled AC air. The use of air conditioners
can lead to tiny droplets that contain the coronavirus being carried on the
flow of air, raising the risks of infection even for people who are some
distance from infected individuals.
An air purifier or air cleaner is purifier which removes contaminants from the
air in a room to improve indoor air quality. When used properly, air purifiers
can help reduce airborne contaminants including viruses in a home or
confined space.
At IntellectPeritus, we have collected around 100 patent documents related to
Indoor Air Sanitizers as sample report and have tried to put value added
technology categories to generate specific insights quickly using our
