Often people do not understand why they feel sick on a regular basis and why we develop symptoms that worsen over time. We hardly know that inside our house, various toxins are present at any time: toluene, xylene, ethyl acetate, methylene, acetone and chloroform, none of which are healthy.

Among other toxins present, three are of major concern: benzene, trichloroethylene and formaldehyde, which could lead to serious health problems like asthma, cancer and various allergies.

In recent years, scientists at NASA and the Associated Landscape Contractors of America (ALCA) have discovered that there are various houseplants that keep our household air clean and pure and balance indoor humidity. Not only do these plants absorb pollutants, they also scrub harmful gases out of the air and help fight pollution. How incredible!

Let's visit a gallery of a few of these beneficial types of houseplants, which can take good care of indoor pollution.

A beautiful houseplant with long grassy leaves, the spider plant is also a rapidly growing plant. This elegant plant is great at removing poisonous gases as well as other impurities like formaldehyde and xylene. For better effect, it should be kept in the kitchen or near the fireplace as these are the places where carbon monooxide accumulates a lot.
