The research of the Nasa

NASA, the us space agency, sought ways to purify the air in space stations.

The list of plants NASA also states the ability to eliminate significant amounts of benzene, formaldehyde and trichloroethylene.

A second and a third list was taken from the book of a certain Wolverton and focused on removal of specific chemicals, such as xylene, toluene, and ammonia.

Also already knew that plants absorb carbon dioxide and release oxygen.

Researchers at NASA suggested for a clean air efficient use of at least one plant for every 10 square metres of space at home or in the office.
