After becoming allergic to New Delhi's polluted air in 1992, Meattle claimed to have discovered that three common houseplants could help reduce the pollutants in the air.<ref>[https://www.ted.com/speakers/kamal_meattle Kamal Meattle Bio]</ref> The three plants and their properties are listed below:<br />
<br />
=== [[Dypsis lutescens|Areca palm]] (''Chrysalidocarpus lutescens'') ===<br />
*Works well in the day time<br />
*Great for living areas<br />
*One needs about 4 shoulder-high plants/person<br />
*Needs to be put outdoors once every 3–4 months<br />
*The leaves of the plant need to be wiped every day in Delhi and perhaps once a week in a cleaner city<br />
*The soil used should be of [[Vermicompost|vermi manure]] or use [[hydroponics]]<br />
<br />
=== [[Sansevieria trifasciata|Mother-in-law's tongue]] (''Sansevieria trifasciata'') ===<br />
*Converts CO<sub>2</sub> into O<sub>2</sub> at night<br />
*One requires about 6–8 such waist-high plants per person in the bedroom<br />
*Leaves need to be wiped in the same way as the Areca Palm<br />
*The soil used should be of [[Vermicompost|vermi manure]] or use [[hydroponics]]<br />
<br />
=== [[Epipremnum aureum|Money plant]] (''Epipremnum aureum'') ===<br />
*Excellent for removing [[formaldehyde]] and other [[volatile organic compound]]s<br />
*Best grown using [[hydroponics]]<br />
