How to Buy the Best Air Purifier in India?
The air quality in India is dismal. Post-Diwali, Delhi has started to
look like an apocalyptic landscape. The future is here, without the
flying cars or personal robots, but with the poisonous air. But even
outside of Delhi, and all through the year, the air quality across major
cities of India has been highly deteriorating. There are a lot of
different reasons for this - rapid construction of our cities, and the
widespread destruction of trees this involves, the huge number of cars,
burning crop stubble in farms, burning trash in cities, and also, the
burning of crackers, all come together to make our cities unlivable.
And while there might be some long term solutions to these problems, the
fact is that just as most of us have gotten used to living with water
purifiers in our homes, it seems we are going to have to accept air purifiers in India too.If pollutants like pollen, dust, dust mites, mould, tobacco smoke, and
pet dander trigger seasonal allergies and have you reaching out for a
box of tissues, you need an air purifier," says Jayati Singh, Business
Head - Air, Philips Personal Health, India. "If you are among the 20-28
million asthmatics in the country. If you have children in the house,
with underdeveloped immune systems, making them particularly susceptible
to air borne pollutants. If someone in your house is pregnant. If your
house/ office is in a construction zone. If you have a pet in the house.
[In any of these scenarios] an air purifier is the way to go."HEPA filterThe problem is that, as consumers, we
don't really know enough about these products to make a good decision
when it's time to buy one. Go online, and you'll see any number of
products on offer, from ionisers that release charged particles to
separate the dust from the air, to humidifiers and other similar
products that claim they will improve the air quality by pushing the
dust out of the air, and air filters that work like a water purifier, in
that it sucks in the air from the room, pushes it through a filter, and
pushes clean air out. These use High Efficiency Particulate Air (HEPA)
filters (or HEPA-type filters in cheaper models), and are used in
hospitals as well - most people recommend avoiding ozonisers and ionizers.
