Alle [[plante]]r [[absorbere]]r [[carbondioxid]] (CO<sub>2</sub>) og frigiver som affaldsprodukt [[oxygen]] (ilt); herudover eliminerer/absorberer luftrensende planter betydelige mængder af en eller flere af disse usunde
* [[Benzen]] – anvendes og frigøres bl.a. fra: [[benzin]], [[blæk]], [[olie]], [[maling]], [[plast]] og [[gummi]].
* [[formaldehyd]] – frigøres bl.a. fra limen i spånplader (møbler, køkkener...). Ved afbrænding af [[naturgas]], [[petroleum]] – og i [[cigaret]]røg.

ScienceDaily] Citat: "...The study concluded that "while ornamental plants are known to remove certain [[flygtige organiske forbindelser|VOCs]], they also emit a variety of VOCs, some of which are known to be biologically active. The longevity of these compounds has not been adequately studied, and the impact of these compounds on humans is unknown."..."</ref>
