What a great idea! I would like to try this at home. Perhaps make a room dedicated to growing these plants outside and then capturing the oxygen via vents and fans.
The three plants you need are:
| common name | name | botanical name | per person | maintenance | function | cost per person |
| the living room
plant |
areca palm | chrysalidocarpus
lutescens |
4 | wipe leaves daily,
take them out doors 3-4 months |
||
| the bedroom
plant |
mother-in-law's tongue | sansevierio
trifasciata |
6-8 waist height | converts oxygen at night | ||
| the specialist
plant |
money plan | epipremnum
aureum |
1 | removes some volatile chemicals |
