Pro Filters airborne toxins
Spathiphyllum was found effective for filtering benzene, formaldehyde, trichloroethyline, xylene, toluene and ammonia from its environment by the 1989 Nasa Clean Air Study.
Pro Low upkeep
Peace lilies prefer shade, and will grow under incandescent bulbs. They need water infrequently, and recover well if watering is delayed.
Con Moderately toxic
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.)
