1. Areca Palm (Chrysalidocarpus lutescens)

• Works well in the day time
• Great for living areas
• One needs about 4 shoulder high plants/person
• Needs to be put outdoors once every 3-4 months
• The leaves of the plant need to be wiped everyday in Delhi and perhaps once a month in a cleaner city
• The soil used should be of vermi manure or use hydroponics

2. Mother-in-law’s Tongue (Sansevieria trifasciata)

• Converts CO2 into O2 at night
• One requires about 6-8 such waist high plants per person in the bedroom
• Leaves need to be wiped in the same way as the Areca Palm
• The soil used should be of vermi manure or use hydroponics

3. Money Plant (Epipremnum aureum)
