Global warming is real, as temperatures rise every year and the heatwave becomes intolerable, especially in cities like Mumbai and Delhi. So personal cooling should become our reality too, sounds only fair, right? Unless you live inside a smoke-belching chimney you probably think the air in your house is pretty clean. Apart from your guffs and the occasional slice of burned toast, what could possibly be making it dirty? The answer: invisible things called Volatile Organic Compounds (VOCs) that are released into the air by cosmetics, cleaning products, scented candles, fumes are created by cookers and fireplaces; and there are all kinds of allergens associated with plants and pets. Dyson has forever been thinking about clean air, and this time around, gone and created the Pure Cool Me (₹25,900) - an air-purifying fan that claims to filter out 99.95% of nasty particles floating about. It’s portable design allows it to be used at the desk if you, like us are glued to your work stations all day, or put it by your bedside and don’t let the nasties in the air hold fresh air back. Point it at your face or set it to rotate through 70 degrees, there’s a sleep timer onboard too, and Dyson’s boffins have made sure it’s as quiet as possible, so it won’t disturb your coughing and sneezing.
