19 Houseplants for Clean Air

Indoor air can be littered with contaminants like formaldehyde from carpets and adhesives, volatile organic compounds (VOCs) from paints, petrochemicals from fragrances, and a laundry list of chemicals from fabric softeners. While it’s always important to let some fresh air in, research by NASA found that many houseplants are capable of reducing harmful toxins in the air, such as: benzene, formaldehyde, trichloroethylene (TCE), toluene, and more.  The NASA – ALCA clean air study recommended 15-18 good sized oxygen producing plants and air cleaning plants for a 1,800 square foot house.

Benzene is a cancer-causing agent found in many glues, solvents, paints, and art supplies. Formaldehyde is a cancer-causing agent that off-gases from furniture and carpets. Trichloroethylene is a solvent used with metal parts, dry cleaning, paints and paint remover. Toluene is found in nail polish and nail polish remover as well as foam.

The two ways by which plants can clean air are by absorbing contaminants through pores on the leaves, and by metabolizing contaminants through organisms living in the soil. To find beneficial houseplants for your home, watch for the labels on houseplants at home improvement stores or nurseries.

Scientific studies have shown the following list of plants to be the leading air-purifying.  Many of them will also remove mold spores and bacteria from the air while contributing to the humidity level.Dracinia Houseplant
