Don’t they filter the oxygen?
Also called the mother-in-law’s tongue, the snake plant is an inexpensive way to bring clean air into your bedroom at night. This low maintenance plant converts carbon dioxide into oxygen while you sleep. The snake plant also eliminates volatile compounds like formaldehyde, trichloroethylene, xylene, toluene, and benzene from the air which are all toxic to humans.
