Peace lily (Spathiphyllum)
Shade and weekly watering are all the peace lily needs to survive and produce blooms. It topped NASA’s list for removing all three of most common VOCs — formaldehyde, benzene and trichloroethylene. It can also combat toluene and xylene.
HGTV Gardens says peace lilies are renowned for their easy care. "The peace lily is hardy, forgiving, and will even let you know when it is thirsty — look for the telltale droop."
