Masks have been used since ages for both ceremonial and practical purposes. I have always had a fascination for different types of masks. Whenever I go to some new place, along with the other knickknacks and souvenirs, I generally bring home a mask, which finds a place on the wall of my living room. However, lately more than the decorative masks, I have been buying face masks for protection against the rising pollution levels.
I got an anti-pollution mask when I went to Delhi last year in November. After Diwali, the air pollution levels in Delhi had reached a phenomenal high. The schools there had declared a three-day holiday during what was being called as the Great smog event, and people were advised to stay indoors. The premise was that inside our house, we were safe from pollution.
It was not until recently that I realized how wrong that perception was. My sense of safety from pollution inside the house was severely challenged after I heard that indoor air can be 5 times more polluted than outdoor air.
