Every winter, the national capital of India gets the same story - the poisonous haze over Delhi skies. The residents always complain of obstructed breathing issues throughout the winters. The ever-increasing problem of air pollution is not limited to winter days but in summers too. The problem is not going to end sooner as pollution levels in India are set to worsen in future. Therefore, the best way to safeguard your health is to invest in a good quality air purifier. But the decision to pick just any purifier doesn't make sense. Instead, there must be a thorough research before picking the best air purifier in India.

By choosing one of the best air purifiers in India for your home, you can at least do your bit to save you and your loved ones from the clutches of severe pollution. So, let's get to know how you can make the best choice.

What is an air purifier?

Just like a home cooler, an air purifier gets air in using a fan and then processes it through extremely fine filter to get it away of particulate matter. Once the particulate matter has been eliminated, the clean part is pushed back into the room. Basis the size of the room and capacity of the purifier, it tends to take anywhere from 10 minutes to an hour to filter.

Things to look while choosing the best purifier

Brand: Today many renowned electronic appliance manufacturers have their air cleaner in the market that claim to provide the best results. According to expert, it is always recommended to choose a leading brand so as to get effective results. Do make sure that the purifier you are buying employs HEPA filters as they are assured to eliminate around 99 per cent pollutants.

Portability and weight: Though there many purifiers that perform as central air purifying device for the entire home, they are costly and may not be feasible for majority of buyers. On the contrary, choose something that sets the right balance between size and performance. A very small air purifier may appear appealing but it may not have sufficient capacity to purify air in a room effectively. While a purifier that is excessively big may not be a wise investment because you may have to use it as a fixed unit in the room.

Capacity: It is really very important to know the effectiveness of an air purifier before buying. And in this regard, one should look for the CADR (clean-air delivery rate). Though many manufacturers try to hide this number from consumers, better working air purifiers tend to have higher CADR number. In general, anything above 300 is wonderful. Anything lower than 100 is not worthy.
