Delhi Air Pollution: Real-time Air Quality Index (AQI)
What is a good PM 2.5 reading?
24-Hour PM2.5 Levels (μg/m3)
|PM2.5||Air Quality Index|
|0 to 12.0||Good 0 to 50|
|12.1 to 35.4||Moderate 51 to 100|
|35.5 to 55.4||Unhealthy for Sensitive Groups 101 to 150|
|55.5 to 150.4||Unhealthy 151 to 200|
Is PM 2.5 really dangerous?
Fine particles ( PM2.5 ) pose the greatest health risk. These fine particles can get deep into lungs and some may even get into the bloodstream. Exposure to these particles can affect a person’s lungs and heart. Coarse particles ( PM 10– 2.5 ) are of less concern, although they can irritate a person’s eyes, nose, and throat.
What is a safe PM 2.5 level?
In the US, exposure to very fine particulate matter known as PM2. 5 is considered safe by the US Environmental Protection Agency’s national ambient air quality standards so long as a person breathes in an average of 12 micrograms per cubic meter of air (μg/m3) or less per day over the duration of a year.
Which area of Delhi is most polluted?
New Delhi : “The Delhi Pollution Authority has identified five new highly polluted regions in the capital. These include Gandhi Nagar, Peeragarhi, Azadpur Mandi, Rohtak Road and Sarai Rohila,” EPCA member Sunita Narain said.
Which city has the worst air quality?
Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2. 5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). List of most-polluted cities by particulate matter concentration.

How can I reduce PM 2.5 at home?
Take additional steps to keep pollution in your home low. Avoid using anything that burns, such as wood fireplaces, gas logs and even candles or incense. Keep the room clean – but don’t vacuum unless your vacuum has a HEPA filter. That stirs up particles already inside your home . Wet mopping can help reduce dust.
How do you solve PM 2.5 Problems?
We can reduce the levels of particulate matter pollution by reducing the amount of particulate matter produced through smoke and by reducing vehicle emissions. Reduce the amount of particulate matter produced through smoke: Stop smoking; if you do smoke, do not smoke indoors. Mulch garden refuse instead of burning it.
How long do PM 2.5 filters last?
Filters can last from 16 to 24 hours of ordinary use, but should be replaced within 8 hours when performing dusty activities.
What does PM 2.5 come from?
PM 2.5 comes primarily from combustion. Fireplaces, car engines, and coal- or natural gas–fired power plants are all major PM 2.5 sources.
What does PM 2.5 do to your lungs?
How can PM2.5 affect my health? Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs . Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath.
What is anti pm 2.5 Mask?
A PM2. 5 pollution mask is a mask that is designed to filter out particulate matter in the air. These particulate matter can include dust, soil, pollen and chemicals. Viruses can also be captured by anti pollution masks like any other particles. 5 refers to particulates that are at least 2.5 microns in size.
Does N95 mask protect against PM2 5?
From all the test result, N95 is good enough for filtering most of the PM2 . 5 particles, but sensitive persons can consider using N99 version of those masks (N99 stands for filtering more the 99% of airborne particles).
What is a normal PM2 5 level?
14, 2012 the U.S. Environmental Protection Agency (EPA) strengthened the nation’s air quality standards for fine particle pollution to improve public health protection by revising the primary annual PM2 . 5 standard to 12 micrograms per cubic meter (µg/m3) and retaining the 24- hour fine particle standard of 35 µg/m3.
