Question
Which houseplants generate the most oxygen?
Which houseplants purify the most air?

Answer
Hi there,

There is a misunderstanding about the idea that certain plants are better producers of oxygen or better air purifiers. Much of this misunderstanding has come from abbreviated reports or excerpts from some research studies done by a former NASA scientist.

The bottom line is that healthy plants that are growing vigorously and that are large and have lots of leaf surface area are best at producing oxygen and cleaning the air. Although there are minor differences from one species to another, the health and size and leaf surface of a particular plant are much more important factors than the plant species.

I recommend that you select plants based on the available light because proper light will affect plant health and growth rate more than any other factor. And a healthy plant is what you want. Match the plants light requirements with the light that you have available for it.

Please let me know if any of this is unclear or if you have any additional questions.

If this information has been helpful, please take the time to give me a rating and nomination.
