Do houseplants actually clean the air in your home? How is Briiv equivalent to 3,043 plants?

This myth came from a study way back in the 1980's by the nice folks at NASA. 
Although we'd love to be able to fill our homes with exotic plants and enjoy cleaner air than the French Alps, this sadly isn't true. 

As plants are static and don't have any air being pulled through them, they just can't physically remove any of the harmful particulates that are floating around in our homes.

Although plants may not clean the air of particles as much as we thought, they do one important thing exceptionally well, and that's to lock away CO2 as they grow and release oxygen through photosynthesis.
