Which Cities in India Have The Poorest Quality of Air?

Air pollution has grown to be a serious issue of concern across the globe. The health problems arising due to an increase in the levels of toxins in the air are alarming. Various factors like the increase in industrialization, overpopulation, and an increase in the number of vehicles on the street contribute to the high pollution levels. India has found a prominent spot in the 14th position when it comes to being the world’s most polluted cities. It has been estimated that about 7 million people lose their lives due to air pollution every year. This is quite an alarming rate as one might least expect to die due to inhaling the toxic air. PM 2.5 is the average amount that has been used to rank the most polluted cities in India. 

  1. Kanpur: The annual average level of PM 2.5 in Kanpur is 173, which is 17 times more than the levels recommended by the WHO. This is mainly due to the leather factories in the city.
  2. Faridabad: This is the second most polluted city in India. The increase in pollution is mainly due to the construction, burning of crops, industrial fumes, and vehicles. 
  3. Varanasi: Being a Holy city, the region enjoys an influx of tourism throughout the year. The average level of PM 2.5 in the city was as high as 151.
  4. Gaya: Again, being a holy city in Bihar, the city is subjected to an increase in tourism throughout the year. The average PM 2.5 level is 149 here, and this is 15 times more than the recommended levels by the WHO
  5. Patna: Located on the banks of the holy river Ganga, this is one of the most polluted cities in India. The average PM 2.5 level is 144 as reported by the WHO.
  6. Delhi– The capital city has been continuously on the news for its toxic air. The condition worsens as the Winter approaches. The average PM 2.5 levels are 114 micrograms as per WHO reports.

Best Air Purifier in India- Buying Guide

There are a few aspects that we need to bear in mind when picking out the best air purifier brand in India. As we place our health dependant upon the efficiency of an air purifier, you must purchase a good one. Let us help you ‘learn’ about a few pointers that will make it easier for you to select rightly:  

1. Types of Air Purifiers: There are five different types of air purifiers:

a. HEPA Purifiers

This is one of the oldest and most trusted technologies. It was first used in the making of gas masks during WWII. Now, it has found a popular application as a household name when it comes to air-purifiers. HEPA stands for high-efficiency particulate air. It functions by straining out the microscopic particles of diameter 0.3 micrometres. The filter has an efficiency of removing 99.97% of particles from the air.

b. Adsorbent Purifiers

These are known to trap both Chemicals and odour in the air. It is also featured in some of the best air purifiers for smoke. The filter makes use of adsorbent materials that attract toxic matter through various physical or chemical processes.

c. UV Purifiers

The UV filters in these purifiers are known to utilize the process of ultraviolet germicidal irradiation to break down the chemical bonds of the microbes. This is useful in the efficient killing of the Viruses and Bacteria present in the air.

d. Ionic Purifiers

This Air purifier type emits ions. The ions are positively or negatively charged particles and are released from the purifier through a process called Corona Discharge. The ions attach themselves to the toxic particles and cause them to settle over solid surfaces. This can easily be wiped off during cleaning.

e. Ozone Generators

This type can utilize either the UV light or the Corona discharge to eradicate the toxic materials in the air. This works by breaking the Oxygen molecule into two separate oxygen atoms. This recombines into the surrounding Oxygen molecule to form a three Oxygen Atom structure. The Ozone filters are widely used in some of the best air purifiers in India and are also efficient. 

2. Filtration Technology

This is the process of filtration where particular laden air is made to pass-through a Porous material. This helps in the separation of the toxic materials from the air and thus resulting in the expulsion of cleaner air on the other side. You need to check through the filtration technology that is applied in a particular Air purifier, as it directly determines the efficiency of the results.

3. Room Size

Room size matters a lot when it comes to the effectiveness of the air purifier. When purchasing the home appliance, be sure to go for the one that has an efficiency of 20-40% more than the one you require for. Air purifiers are available to work in three specific room sizes:

155sq ft- Small Room
300 Sq ft- Medium Room
500 Sq ft- Large room

4. ACH and CADR

ACH- Air change per Hour

CADR – Clean Air Delivery Range

These are the two terms one needs to learn of when selecting the best air purifier and humidifier in India. You need to follow the 2/3 rd rule. According to this, you need to go for an air purifier that has a CADR of more than 2/3 rd of the room in sq ft with a maximum height of 2.4 meters. 

As for the ACH levels, it is recommended a minimum rating of 4.

5. Maintenance

Good maintenance is the key to efficiency and fine working of an air purifier. The user needs to learn a few pointers when operating the appliance:

  • When you have to clean or move the air purifier, be sure to unplug it.
  • It is essential to clean the Pre-filter at least once a month
  • Make sure that the Pre-filter is completely dried before you place it back into the device.
  • The HEPA filter can be cleaned through gentle vacuuming once a month. This helps remove the pollutants and particles caught-up on its surface.
  • It is prohibited to use water or regular household detergent to clean the filters.
  • Also, never apply force or pressure when cleaning the surface of the filter.

6. Energy Efficiency

The air purifier is one appliance that needs to be on a work-mode round the clock. This can lead to various energy consumption concerns. It is therefore recommended to opt for a choice that is energy efficient in its workings. There are some of the best air purifiers in India that are designed to be cost-effective. These types are known to be 40% more efficient and can save up to 225 kWh in yearly savings. It is necessary to go for this option as every one of us needs to be responsible for our environment.

7. Placement
