With more than 10 Indian cities in the list of top 20 most polluted cities in the world, as per WHO, an air purifier is a must whether you’re at home or in the office. The best air purifier is one that can efficiently clean the air of a given area without taking much space while keeping the noise decibel level as low as possible. We’ve compiled a list of the best air purifiers across price ranges, designed to be compact yet powerful and to clean the air in the room within a short span of time. Brands such as Xiaomi, Dyson, Philips, Panasonic, Honeywell, Kent, and Atlanta Healthcare are on top of buyers’ minds when they are looking to buy the best air purifiers in India.
Before we get down to the list of the best air purifiers in India, here’s a quick explainer on elements that make an air purifier worth buying. There are no formal standards on buying air purifiers in India yet but do keep these points in mind when you are out looking to purchase one.
- Pre-filter – This is used to filter out the PM10 particles – PM10 refers to large particulate matter (10 micrometers in size).
- HEPA filter – It’s the most important component of an air purifier as it filters the PM2.5 particles. PM2.5 is the finer particulate matter (2.5-micrometre in size) that is small enough to enter the lungs undetected and cause long-term damage.
- Activated carbon filter – The filter traps gases and removes the odour. It should be noted that while the pre-filter can be washed (much like the pre-filter of an AC), the HEPA filter cannot be washed and must be replaced.
- CADR or Clean Air Delivery Rate – This is the speed at which an air purifier cleans the air in the room (measured in cubic meters per hour or m3).
- Size – An air purifier that has a larger coverage area than the room you’re going to use it in is more effective, consumes less energy, and will be quieter. So make sure you have the right dimensions of the room in mind before you make the purchase.
- Whatever else you get are just brownies on top. These include remote control, wireless connectivity, humidifier, and display, among other things.
