NASA scientists studied the relationship of houseplants and air quality and came up with a list of the plants that are most efficient at reducing indoor pollutants. The NASA studies generated the recommendation that you use 15 to 18 good-sized houseplants in 6 to 8-inch diameter containers to improve air quality in an average 1,800 square foot house. The more vigorously they grow, the better job they'll do for you. Those plants include: Hedera helix (English ivy), Chlorophytum comosum (spider plant), Epipiremnum aureum (golden pothos), Spathiphyllum `Mauna Loa' (peace lily), Aglaonema modestum (Chinese evergreen), Chamaedorea sefritzii (bamboo or reed palm), Sansevieria trifasciata (snake plant), Philodendron scandens `oxycardium' (heartleaf philodendron), Philodendron selloum (selloum philodendron),
Philodendron domesticum (elephant ear philodendron), Dracaena marginata (red-edged dracaena), Dracaena fragrans `Massangeana' (cornstalk dracaena), Dracaena deremensis `Janet Craig' (Janet Craig dracaena), Dracaena deremensis `Warneckii' (Warneck dracaena), and Ficus benjamina (weeping fig). Hope this list is helpful.
