Guide to buying Air Purifiers in India

Important points to consider before buying Air Purifier in India

With rising levels of pollution and increasing threats to health from the diseases caused, people are resorting to air purifiers to breathe in clean air. I recently bought one for my home too. There are ample air purifier choices available in the market today, which really confuses the buyer. The most important consideration for me was of course the price, technology and also the brand reputation, since the filters need to be replaced from time to time and hence should be available in the market. While they claim to be non-hazardous in nature, caution should be exercised while choosing your device, since some technologies might not be very suitable for your health in the long run. For example air purifiers that use UV light or ionisation can bring down your immunity level over some time.

Different technologies used in Air Purifiers:

1)Filters – Filters help to filter out pollutants in the air, especially large particulate matter and heavy pollutants that are present in the Indian air. Generally the purifiers have a HEPA and a carbon filter. However one needs to change these filters from time to time, which will add to expenses.

2)Ionisation – Air purifiers also use the ionisation technique, wherein the charged particles or ions attract the polluting molecules from the air.

3)Nanotechnology – This technology removes nitrogen oxide and sulphur oxide and the harmful volatile organic compounds.

Other technologies include ozone generators and UV light radiation to purify the air.

Top Air Purifier sellers in India

1) Sharp Air Purifiers

Sharp air purifiers offer a range of air purifiers specifically for general purpose in homes, offices, restaurants etc and for specialized purpose like in airports, hospitals etc. Sharp uses Plasmacluster ion technology in addition to its active filters to purify the air. The plasmacluster ion technology splits the moisture in the room into positive hydrogen and negative oxygen ions, which attach to the unwanted components in the air and help in purification. Sharp thus purifies the air using dual air-purification techniques through ions and filters. Some of the Sharp air purifiers also come with humidifiers that help to maintain air humidity level between 55% and 65%, ideal for human body.

The air purification still takes place within the device itself and not in the room. Furthermore, unwanted particles are not broken down, nor are the cell walls of the micro-organisms damaged in these cases.
