S. trifasciata was found effective for filtering benzene, formaldehyde, trichloroethyline, xylene and toluene from its environment by the 1989 Nasa Clean Air Study.
S. trifasciata contains saponins which cause pain, salivation and nausea when ingested. In pets and children this can progress to vomiting and diarrhea.
Though it prefers humidity and bright indirect sunlight, D. marginata remains healthy in most room conditions. It should be watered only when the top of the soil is completely dry.
Dracaena marginata was found effective for filtering benzene, formaldehyde, trichloroethyline, xylene and toluene from its environment by the 1989 Nasa Clean Air Study.
Though D. marginata will survive most indoor environments, a lush and healthy plant requires good light and daily misting, and should be repotted anually.
Spathiphyllum was found effective for filtering benzene, formaldehyde, trichloroethyline, xylene, toluene and ammonia from its environment by the 1989 Nasa Clean Air Study.
Spathiphyllum contains calcium oxalate, a severe irritant. Some individuals may suffer skin rashes from handling the plant. Ingestion causes burning and swelling of the mouth and throat, as well as nausea and vomiting. In pets, this can progress to kidney failure if left untreated. (Note that Spathiphyllum is not a true lily, and rarely lethal to pets.)
