10 Best Plants You Can Grow Indoors for Air Purification

Harmful pollutants arise from cigarette smoke, paint, plastics, chemicals in carpets, cleaning solutions and numerous building and furniture materials.

Indoor air pollutants can trigger coughing, chest tightness, frequent headaches, sore throats, watery or itchy eyes, shortness of breath and asthma attacks.

Some of the most dangerous indoor air pollutants include carbon monoxide, radon gas, formaldehyde, benzene, ammonia and trichloroethylene.

We often think of pollution as an outdoor problem, but indoor air can also be polluted with harmful chemicals. According to the U.S. Environmental Protection Agency, people spend 90 percent of their time indoors and poor air quality can cause great harm to their health.

Nature offers a simple and effective solution for indoor air purification. Many plants help remove pollutants from the air naturally.

In fact, a 1989 NASA study suggests having at least one houseplant with air purification power for every 100 square feet of home or office space.

However, be careful in your selection of houseplants if you have pets in your house as some houseplants such as English ivy, red-edged dracaena, peace lily, weeping fig, rubber plant and florist’s chrysanthemum can be toxic to pets.
