|When NASA was looking for ways to purify air in space stations, they studied plants. Common houseplants freshen indoor air by removing toxic chemicals.The studies looked at several representative kinds of toxins: formaldehyde, benzene, tricholorethylene, ammonia, carbon dioxide and nitrogen dioxide.|
Though all plants probably have some filtering ability, the following plants did the best job in combating indoor air pollution:
Heartleaf Philodendron - Philodendron scandens 'oxycardium'
Elephant Ear Philodendron - Philodrendron domesticum
Cornstalk Dracaena - Dracena fragrans 'Massangeana'
English Ivy - Hedera helix
Spider Plant - Chlorophytum cososum
Janet Craig Dracaena - Draceaena dremensis
'Warneckii' Dracaena - Dracaena dremensis
Weeping Fig - Ficus benjamina
Golden Pothos - Epipiremnum aureum
Peace Lily - Spathiphyllum 'Mauna Loa'
Selloum - Philodendron selloum
Chinese Evergreen - Aglanema modestum
Bamboo Palm - Chamaedorea sefritzii
Mother-in-law's Tongue - Sanseveria trifasciata
Red-Edged Dracaena - Dracaena margnata
Spider plants are good at removing carbon monoxide and nitrogen dioxide.
The best plants for removing trichloroethylene (found in paint, varnish, adhesive and ink) are dieffenbachia, English ivy, gerbera daisies, chrysanthemums, peach lily, bamboo palm, Dracaena Warnecki, and mother-in-law's tongue.
Formaldehyde is most effectively removed by spider plants, bamboo plams, golden pothos, peach lily, Dracena Maginata, Dracena "janet Craig", mother-in-laws' tongue and philodendrons. Think of these plants when you get new furniture or are remodeling.
Painting? Benzene is in paints and oils, and is used as solvents. The best plants to remove benzene are dieffenbachia, English ivy, gerbera daisy, chrysanthemum, peach lily, bamboo palm, Dracaena Warneckei, and mother-in-law's-tongue.
One plant cleans about 100 square feet. About 15 planst in six inch posts will be enough for a home under 2,000 sq. ft.
