5 Questions Know How to Start Refreshing Air
Some common questions for you to learn how to start refreshing the air around you.
If you don’t know the benefits of indoor air filtration, we have answered some common questions for you to learn how to start refreshing the air around you:
1.What should the air quality be?
The World Health Organization states levels of different sizes of particulate matter (PM) that enter the respiratory tract in the air should be no higher than 10μg/m³ for PM2.5 and at or below 20μg/m³ for PM10.
According to the air quality index, the PM2.5 level between 0-50 has little risk to health; 51-100 may be at risk to a few sensitive people; 101-150 is unhealthy air quality for sensitive groups; Anything over 150 is unhealthy and dangerous. The indoor air filter in the high quality HEPA indoor air purifier will keep the air quality of your building at a safe level.
2.What is a HEPA filter?
HEPA filter is a particulate filter, which can remove more than 99% of the smallest particles in the air, such as dust, mite eggs, pollen, smoke, bacteria and aerosols.
3.Why do we need to create a healthy indoor air filtration system?
Harmful particles and gases in the air have adverse effects on human health. During the outbreak of airborne viruses, people are increasingly concerned about the quality of the air we breathe. For example, the current COVID-19. Virologists agree that COVID-19 is mainly transmitted through respiration, while it is not very common to transmit it through surface smears or droplets. Cleaner air contains fewer aerosols that carry these infectious particles.
4.How do indoor air purifiers work?
What does an indoor air purifier do? We know that COVID-19 can be transmitted through airborne aerosols, and indoor air may contain more infected aerosols. These tiny droplets are released into the environment by breathing and speaking, and then spread throughout the room. Air purifiers play a vital role in improving indoor air quality by reducing virus concentrations in air that cannot be effectively ventilated.
