Our bodies are exposed to toxic chemicals everyday, from objects around us. Air-filtering plants can get rid of these chemicals, and these 12 are also safe around pets.

The researchers at NASA have put together a list of around 30 air-filtering plants for the home, filtering out benzene, formaldehyde, trichloroethylene, xylene and toluene, and ammonia.

Where do these chemicals come from and what do they do?


Benzene is among the 20 most commonly used chemicals in the USA. It is mainly as a starting ngredient in other chemicals, in plastics, rubbers, dyes, drugs, pesticides, detergents and lubricants. It naturally occurs in crude oil and gasoline, which means it appears in vehicle exhaust smoke, as well as cigarette smoke.

It is formed from natural processes, such as volcanoes and forest fires too, but exposure is higest from human activities.

Symptoms include drowsiness, headaches, eye irritation, dizziness and confusion.


Found in synthetic fabrics, paper bags, waxed bags, insulation, plywood panelling and more. It is released from these materials into the air around us.

It also occurs naturally in the environment, produced in small amounts by most living organisms as part of normal metabolic processes.

Symptoms associated with short term exposure include nose, mouth and throat irritation, and swelling of the larynx and lungs.


Found in printing inks, lacquers, adhesives, paints and paint remover.

Symptoms include dizziness, nausea and vomiting, headaches, and dowsiness.

Xylene and toluene

Found in the leather and paint industries, in tobacco smoke, vehical exhaust fumes, rubber and printing.

Symptoms with short term exposure include headaches, dizziness and throat irritation , and heart problems, liver and kidney damge and coma.


Found in window cleaners, smelling salts, floor waxes and fertilzers.

Symptoms include eye irritation, sore throat and coughing.
