Houseplants are a fun and easy way to green up the indoors, but did you know that they can also help clean and remove toxins from the air? Out of all of the common houseplants, 35 of the best indoor plants excel at this task. I’ve created a comprehensive list based on a study NASA performed several years ago that tested the efficiency of different plants and their toxin-removing powers. If you don’t have at least one or two in your home, you should consider adding them. 

As a bonus, many of these best indoor plants are considered great for beginners because they’re very forgiving, easy to grow, and easy to maintain. You’ll get a short overview of the plant, how to care for them, and any additional features they have below.

With proper care, these bamboo plants can live for years and grow at a slow rate. 

4. Banana Plant

Both outdoor and indoor banana plants need a very humus-like and rich growing medium that drains very well. They also require plenty of indirect sunlight, and many varieties need at least 12 hours every day.
