Grow Clean Air!

In this TED Talk, Indian research Kamal Meattle shows how an arrangement of three common houseplants, when used in specific spots in a home or office building, can result in measurably cleaner indoor air.

With its air-filtering plants and sustainable architecture, Kamal Meattle's office park in New Delhi is a model of green business. Meattle himself is a longtime activist for cleaning up India's air.

The three house plants Kamal suggests are:

Areca Palm

Mother In-Laws Tongue

Money Plant (Golden Pothos)
