There are many plants that reduce VOC's (volatile organic compounds) in indoor environments. That is a fancy way to say they clean the air in our indoor living and work spaces. Pothos among these is arguably the easiest houseplant to care for. Also Aglonema, Spath, and Nephytis are among the popular air cleaners. There are many more but all that I have mentioned are very easy care, the Spath (peace lilly) would require the most attention of all that I have listed, it has an incredibly dramatic but not fatal reaction when it runs low on water.
