In the last few years, pollution has increased drastically, and India has some of the most polluted cities in the world.

In the top 20 most polluted cities globally, our country has 13 cities that include, Kanpur, Faridabad, Gaya, Gurugram, Varanasi, Agra, Muzaffarpur, Bhiwadi, Lucknow, Ghaziabad, Jaipur, Patiala, and our capital Delhi.

Apart from these, there are 100s more, that have intolerable pollution levels. Much higher than most cities in the developed world.

Also, pollution has become excessive in North India (NCR, Haryana, Punjab) after Diwali, and also due to the burning of stubble by farmers.

With an ever-increasing population, we are not able to control pollution. Extreme air pollution causes irreversible damage to our lungs and inhaling this foul air can lead to several pulmonary diseases.

This is one of the reasons why Air Purifiers came into the spotlight, that at least protects our home, office/workplace and offers better Air.

What Is An Air Purifier?

Air Purifier is a device that cleans or sanitizes the air present in the atmosphere and removes the pollutants such as particulate matter, toxins, bacteria, and viruses. In simple words, Air Purifier filters out the hazardous substances present in the air and gives us clean air.

I recently bought one Air purifier (Philips AC2887) for my office that is located near a road and desperately needed fresh air. So far the experience is good and if you are living in a polluted environment, having an Air Purifier is essential for your health.

I will try to help & get you the best purifier as per your requirement and budget.

What things to consider before buying an Air Purifier?

  1. Size of your room – The size of your room decides the capacity of the Air purifier that you are planning to buy. Smaller offices or rooms can be cleaned easily with basic Air purifiers.
  2. Presence of HEPA Filter – Generally, there are two filters present in Air Purifiers – A Composite filter and a HEPA filter. But HEPA is the most important filter between them because it filters pollutants from Air mechanically. Some Air Purifiers also have a Carbon Filter that can remove the foul smell from the Air.
  3. Presence of LED-Indicator – The LED indicator is essential for showing if you need to change the filter or tells us the real-time pollution level.
  4. Performance – The performance of the Air purifiers is measured using two measurements – CADR and ACH.
    • CADR – It stands for Clean Air Delivery Rate, it indicates the level of Air emitted by an air purifier. A higher CADR tends to higher filtration capacity.
    • ACH –  It stands for Air Changes Per Hour, it tells us how many times an air purifier purifies the air of the room.

So, these are some of the things which you can keep in mind before buying any Air purifier.

For your ease, we have done some deep diving and selected the top 10 air purifiers that you can buy currently for cleaning the air in your home or small office.
