Chlorophytum
Chlorophytum:
One pot of Chlorophytum in a 8-10 square meters of room is enough to perform as an air filter, which releases oxygen and absorbs Carcinogens like formaldehyde and Styrene. Chlorophytum is very strong in absorbing carbon monoxide and formaldehyde normally up 95% and 85%. It decomposes benzene and Nicotine in tobaccos. So they are called green filters.
