In between all the measures to battle the severe air pollution levels in Delhi, there’s one more option for you — a bar that has “pure air”. Delhi’s first-ever oxygen bar — named “Oxy Pure” — offers 15 minutes of 80-90 percent pure oxygen starting from Rs 299.

The bar,     1     in May, also offers its customers several aromas（香味）to choose from that can be filled with oxygen. The aromas include lemongrass, cherry, mango and more.

Customers are given a lightweight tube, used for supplementary oxygen     2    . The device is placed near the customer’s nose through which they are advised to breathe in the aroma-filled oxygen.

According to the aroma you choose, each session     3     to improve one’s sleep patterns and digestion, cure headaches and even claims to work as a remedy for     4    .

“I was passing by and saw that they were offering pure oxygen. I thought I would give it a try and went for the lemongrass flavour. It was     5    ,” Manjul Mehta, a customer at Oxy Pure told Delhi Daily.

Speaking to Delhi Daily, Bonny Irengbam, senior sales assistant at the bar, said customers were     6     positively after a few sessions.

“Some people, who try it for the first time, will feel relaxed and fresh. But only people who undergo the sessions regularly will get real     7     of the aroma,” he added. “Though we have regular customers, we don’t encourage back-to-back sessions, as     8     levels of oxygen in the body can make a person dizzy. It is     9     to do it once or twice a month or to stick with the 10-15 minute sessions a day,” he said.

Dr. Rajesh Chawla, a senior consultant in medicine said that though such sessions do not have any side-effects, it does not help in the long run either. “Even if you breathe in the so-called pure oxygen for two hours in a day, you will go back to breathing the polluted air for the rest of the 22 hours”, he said. He added that the concept is purely a(n)     10     move.
