How essential is an air purifier?

Air pollution is a burning topic in India. As per a recent WHO report, India has 13 of the 20 most polluted cities in the world. Every year approximately 1.3 million Indians die of diseases caused by air pollution.

Indoor and Outdoor Air Pollution.

Emission from vehicles, industrial emission, construction and burning of agricultural and household wastes etc. are the major contributors to air pollution.
There is a misconception that indoor air is safer than the air outside, but Indoor air is as dangerous as the outdoor air due to additional polluting factors like cooking, mould spores and bacteria, pet fur and dust trapped on carpets and other surfaces.
The air quality worsens in winter due to atmospheric factors (temperature inversion, valley effect, etc.) and due to the additional pollutants entering the atmosphere from burning of biomass for heating.

AQI – Air Quality Measurement

AQI is an index used for Air Quality measurements. AQI below 50 is considered good and as the number increases the quality of air deteriorates.

Do I need an Air Purifier?

Are you living in one of the metros/cities where the pollution is higher than the safe levels? Then it is advisable to use an air purifier to manage indoor air pollution levels.
Before deciding to buy an air purifier, it is advisable to check the Air Quality in your city. You can check the Air Quality Index of your town at the below link
https://www.aqi.in/
If the AQI values are below 100 and family members are not hypersensitive, then an air purifier is not necessary. However, if family members are sensitive to dust/allergens or if the AQI index is higher, then it is advisable to have an air purifier.

Which type of Air Purifier should I choose?

Multi-stage purification.

These days most air purifiers have multiple filters to perform multi-stage purification. For an Air Purifier to be effective against the PM10 and PM2.5 pollutants it should have a HEPA filter. HEPA filters can also filter out standard allergens from the air. The activated carbon filter can remove odour from air to some extent. Additionally, some air purifiers can eliminate bacteria and viruses by subjecting them to UV radiation. Some air purifiers have an ozone generator, ozone is a strong oxidizing agent and can disinfect the air. Ozone is a secondary air pollutant which can harm human health. So, it is advisable to avoid air purifiers with ozone generators.
If you are allergic or if you live in an area where the air quality is bad, you should always select an Air Purifier with HEPA filter.

Optimum Clean Air Delivery Rate (CADR)

CADR is the measure of air purified by an air purifier in cubic feet per minute. A higher value indicates higher efficiency. While buying an air purifier, check the CADR of the device.

Coverage of the Air Purifier

Air purifiers are effective only over a limited area. While selecting a device check the specification to find the effective area the air filter can purify. Walls and other obstructions will reduce the coverage of the machine so it should be placed away from such obstructions.

Power Consumption

Ideally, an Air Purifier should be allowed to work at least 18 hours a day; the device should be energy efficient.

Frequency of Filter Replacement

The filters should be replaced periodically (as mentioned by the device manufacturer) for the purification to be effective. If the Air Purifier has multiple filters, they should be replaced as well. The filters are moderately expensive. So consider filter replacement costs while deciding on an air filter.
