Factors You Should Consider while Choosing Air Purifier in India


HEPA Filtration

High-efficiency particulate absorbing, also known as HEPA, is an air filtration process in which the machine pushes the air through a thin mesh. The pollutants get trapped in this mesh, and what comes out is clean, breathable air. In current times, HEPA filtration is considered the best system available in the market for homes and offices. The standard benchmark for the size of particulates that it should be able to capture is 0.1 micron.

Maximum Air Exchange Rate

The maximum air exchange rate can be defined as the amount of air that can pass through the filtration process in one minute. Make sure you get the purifier that has a higher air exchange rate.

Filter change alert

Depending on the model you choose and the condition of air at your home, you will need to change the filter after some time. The air purifier should have a system that can inform you when the screen is due for a change.

Air Quality Monitor

The air purifier should have an air quality monitor that tells you about the level of pollutants in the room; it is operational. It helps in keeping a check on the quality of the air around you. Some purifiers come with multiple speed options which help in cleaning the air at different speeds. You can choose based on air quality.


You should check the capacity of the air purifier before you make the purchase. Every purifier has a different capacity and can clean only a specific size of the room. Choosing the wrong purifier for your home or office will not serve the purpose.

Avoid Ozone Air Purifiers

The process in which the purifier uses ozone gas to clean the air is known as Ozonation. It is beneficial when you want to kill microbes, mold, or remove foul smell. However, this type of system comes with a price. If anyone inhales Ozone even in a small amount, it can cause chest pain, shortness of breath, coughing, and throat irritation. In case severe ozone poisoning happens, it can cause severe and irreversible damage to the lungs. Thus it is essential to avoid Ozone based purifiers for home.

Different Types of Air purifiers in the Indian Market

HEPA Air Purifiers

These purifiers were developed to filter radioactive particles, and in the last few years, they have gained a lot of popularity because of their possible applications. It is the best purification system available in the market and can remove particulates as small as 0.001 microns. The complete process is divided into multiple stages to ensure the best results.

UV Air Purifiers

Ultraviolet light is a popular way to kill micro-organisms. It is one of the most suitable methods of disinfecting indoor atmosphere, especially in hospitals and labs. It can kill any bacteria and pathogen in the air, but the problem is it cannot remove dust, debris, and allergens from the air around you. If the purifier you are choosing has UV filtration as a part of the whole purification system, only then you should opt for it. Also, some companies promote their purifiers as UV based, but in reality, they have Ozone based filtration system which will do the same job but have the potential to put your health at risk as well. Thus it is essential to be very careful.

Ozone Air Purifier

The ozone purification system is only ideal for locations where you have mold, foul smell, or pathogen problem, and you want to get rid of it. Otherwise, keeping in the health problems associated with Ozone in mind, it is better to avoid it.
