Islands of quality

摘要

The Paharpur Business Centre in Delhi offers the sort of amenities its blue-chip tenants expect: resident secretaries, payroll services, leased telecom lines. It also supplies custom-made air. The trees nearby are scrubbed with high-powered hoses to improve the local atmosphere in one of the world's most polluted cities. Indoors, the air is further filtered to near-mountaintop quality. Tenants can monitor Paharpur's air quality on the company's website.
