Want to buy an air purifier amid increasing air pollution? Keep these tips in mind while buying

As soon as winter begins, the cities of North India start drowning in poisonous smog. Burning of stubble in the fields, increasing traffic, construction work and stoppage of cold winds, all these together poison the air.

According to experts, in the month of November, the amount of particulate matter (PM2.5) in Delhi’s air exceeds the World Health Organization limit by 20 times. In such a situation, air purifier is no longer a luxury but has become a necessity, but it is very important to keep certain things in mind while purchasing it.

First of all understand Purification Technology. A good air purifier is equipped with multiple layers of filters. Pre-Filter first traps dust, hair and large particles. After this, the HEPA Filter removes microscopic particles present in the air, such as PM2.5, bacteria and allergens.

Whereas the Activated Carbon Filter absorbs the odor, smoke and harmful gases present inside the house. Some advanced models also have an Ionizer Filter, which neutralizes small particles present in the air. The second important thing is Coverage Area. If the size of your room is large, then a small purifier will not be able to clean the air.

Before purchasing, know the area of ​​your room and choose the purifier accordingly. Also look at the CADR rating, which tells you how quickly the device can clean the air. The higher the CADR, the better performance you will get.

Third thing is Noise Level. If you are buying a purifier for the bedroom, then choose only a low-noise model. Nowadays, there are many devices available which have the option of Silent Mode, so that your sleep is not disturbed. Apart from this, it is important to pay attention to energy efficiency, because the air purifier remains on for many hours.

Choosing an energy-efficient model will also reduce electricity bills. Also, filter replacement should be easy so that it can be changed regularly. In today’s era, purifiers with smart features are also being liked a lot. Features like Wi-Fi Connectivity, App Control, and Air Quality Indicator are available in these. With this you can check the air quality and switch the device on and off right from your mobile.
