Buyer’s Guide/ Things to Remember

Buying an Air purifier is still a tough task for most of us. Before buying an air purifier for your home you need to have a look at various aspects of it. There are already too many brands, models & types of air purifiers in India.

So to help you with this we have listed some of the factors that one must need to keep in mind while buying an air purifier for your home.

Choose the Right Filter

Air purifiers mostly use two types of Filters, One is composite and the other one is HEPA composite. To choose the best air purifier of India for your home, always go with the air purifiers having HEPA composite filters.

HEPA filtration is the most effective type of filtration process to remove small dust particles. HEPA Filters have the ability to remove particles down to the size of 0.1 microns. There are other Filters as well in the market but only a few of them can catch the effectiveness of HEPA Filters.

Choose the one with Higher CADR

CADR stands for Clean Air Delivery Rate which represents the amount of purified air an air purifier is emitting every hour. So always choose the air purifier with Higher CADR.

Check ACH before buying

ACH stands for Air Changes per hour, which means how many times the air has been filtered through the air purifier. So Check according to the pollution level of your city & choose the right filter with good ACH value.

Look for the Air Quality Indicator

This will help you a lot to monitor the indoor air quality in real-time. Always choose the smart air purifier. Smart purifiers will:

  • Automatically change the fan speed according to the AQI.
  • Display real-time AQI.
  • Display the Humidity level of the room.
  • Be operational by the Mobile App.

Quiet air purifier

Air purifiers are not as silent as they promise. So always check the noise level of an air purifier before buying. According to the WHO while sleeping human ear can handle a 35-40db sound level without giving any stress to the body.

Most of the air purifiers produce noise in the range of 35-70db based on their fan speeds. While breathing only a human make the sound of range 0-30 db and if you are talking then it goes to 30-60 db. So don’t buy a very talkative air purifier for home.

Perfect for your Room

All air purifier is designed for different types of rooms. Search for the one which will be perfect for your room or house.

For example, if you want one air purifier just for your bedroom you might not need the one with large coverage area. So choose wisely.

Budget Friendly

There are already so many models of air purifiers in India. So choose the one that fits under your budget.

Energy Efficiency

Check the power consumption of the device before investing. This will save the environment as well as your pocket from the heavy electricity bills.
