An AQI above 400 is considered “severe” and can affect healthy people and seriously impact those with existing illnesses.

Delhi Air Quality Index (AQI)

According to the Central Pollution Control Board (CPCB), the concentration of lung-damaging fine particles known as PM2.5 was above 450 micrograms per cubic metre, around eight times the safe limit of 60 micrograms per cubic metre, in many areas. PM 2.5 level from 61 to 120 is considered “moderate to poor”, 121 to 250 is “very poor”, 251 to 350 is “severe” and more than 350 is “severe plus”. Air purifier reduces air contamination inside the house along with indoor pollution.

Hence, air filters with good High-Efficiency Particulate Air (HEPA) efficiency are more effective in combating indoor pollution. As air pollution in Delhi hits an alarming level, people are queuing up to buy air purifiers to protect themselves from the toxic air. 

According to Muzaffar Izamuddin, Design Manager, Environmental Care at Dyson, every year during this season, we tend to witness a rise in AQI levels, and this year is no different.  While we may be aware of outdoor air pollution, awareness of indoor air pollution remains low, and this can be up to 10 times worse than outdoor air pollution. 

There are a number of ways to help improve your personal air quality exposure such as adapting your daily routine to include fewer polluting activities, as well as using a purifier to control your indoor air quality. 

“Dyson’s purifying technology senses air quality, allowing you to monitor and remove pollutants inside your home. Combined with our air multiplier technology and advanced HEPA filtration, Dyson air purifiers can tackle indoor air pollution and help improve your well-being at home.safeguard themselves,” Izamuddin added.

What is HEPA 

A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites and tobacco smoke. A HEPA filter sucks airborne contaminants and pushes out clean, fresh air.
