NEW DELHI: At a time the entire Delhi is struggling for clean air, there's one spot in the city where you can breathe "pure oxygen" for 15 minutes.

While pure oxygen is considered odourless, "Oxy Pure", opened in May this year at Select City Walk, offers it in various flavours such as eucalyptus, lavender, vanilla, peppermint, gardenias, spearmint, lemongrass, cinnamon, orange, cherry among others.

The bar, a first-of-its-kind in Delhi, charges Rs 299 to Rs 499 for 15 minutes of pure oxygen that the owner, Aryavir, claims works like magic on those complaining of mental fatigue, sleep disorders, blood pressure issues and stress.

When pollution levels have spiked, portable oxygen cylinders are also in vogue and are being bought through e-commerce sites.

The bar, which receives around 15-20 customers on any ordinary day, has been witnessing an appreciable growth in business amid a public health emergency due to a harmful spike in pollution levels.

"We have been receiving 25-30 people every day. You can say it's because of extreme pollution which is killing everyone," said Bonny Irengbam, the head staff.
