7 Best Clean Air Plants for Your Home or Office

As homes become more efficient and better insulated, more air pollutants can be trapped inside. Every house and office has indoor air pollutants. From chemicals in carpet and paint to chemical cleaners and stagnant air, these indoor pollutants, such as benzene, formaldehyde and ammonia, have been ranked among the top five environmental risks to public health. And, they are brought in by everyday things such as carpet, household cleaners, paint, insulation, pressed-wood, to name just a few.

These indoor pollutants can contribute to asthma, illness, allergies, headaches and more. The scientists at NASA have been working on finding solutions to this issue and they’ve discovered that some houseplants can actually help clean the air for us, with the added benefit of bringing a bit of nature’s beauty inside. A great and inexpensive way to combat a very real problem.

How do houseplants clean the air?

They absorb some of the air particulates when they take in carbon dioxide, which is processed into oxygen through photosynthesis. Microorganisms associated with plants are present in the potting soil and these microbes are also responsible for much of the cleaning effect. Plus, studies suggest that indoor plants may make people smarter by keeping them alert and reducing mental fatigue.

How many clean air plants do you need?
To be effective, it’s recommended that you’ll need at least two plants per 100 square feet of space, or 15 to 18 good-sized houseplants in an 1,800 square foot house. Even if you have less than that, any clean air houseplants you add will help.

Which clean air plants should you add to your home and office?
To make it easier on you, here are our top 7 clean air plants:
