How many plants would you need in your house to improve indoor air quality?

Question

I’ve heard people say plants in the home can improve air quality, because they breathe the carbon dioxide we exhale, and they exhale fresh oxygen, and also sometimes pollutants and particulate matter get breathed in by the plants too, taken out of the air.

But would you need like an impractically large amount of plants to accomplish this? I can’t imagine a single flower pot in a bedroom is doing much.

It’s a myth. Plants do remove certain pollutants but the rate at which they do it is minuscule. You’d get ten times the benefit by opening a window for example. Keep indoor plants because they look good but don’t expect any measurable change to air quality.
