Houseplants: Do you know that air pollution is one of the five great threats to human health in the world?
Air pollution is associated with several diseases including asthma, headache, chemical sensitivity, and even cancer.
The concentration of many domestic pollutants is two to five times higher than that of outdoor. Fortunately, by using houseplants we can bring a part of nature to our homes to have a healthier environment.
In the late 1980s, NASA researchers investigated the ability of houseplants to clean the air and remove toxic agents such as benzene.
They published a list of plants that can clean the air. It is best to have the following plants at your home or work office to breathe easily:
Aloe vera
This plant is a native to South Africa that absorbs benzene and formaldehyde of the air.
Aloe vera releases oxygen and absorbs carbon dioxide at night and it is ideal for the bedroom.
Areca Palm
This palm is native to Madagascar and is one of the best plants to eliminate all kinds of toxins, especially formaldehyde.
English ivy
Hedera helix commonly known as English ivy, is a plant that grows well at home and is suitable for the bedroom.
Researchers believe that this plant will eliminate all indoor air pollution within 12 hours.
Spider Plant
It is native to Africa and removes formaldehyde, benzene and xylene found in auto exhaust, synthetic perfume and paint.
NASA found this plant can remove 96 percent of the carbon monoxide and 99 percent of the nitrogen dioxide within a sealed chamber.
Ficus benjamina
This plant is also one of the excellent air cleaner that eliminates all pollution from carpets and furniture such as formaldehyde, benzene and trichlorethylene.
Peace Lily
Peace Lily or spathyphylum flower is a beautiful plant that can remove to 60% of indoor air pollutions and toxins.
The interesting thing about this plant is that it absorbs very small pollen or spores through its leaves and uses its roots as food.
Aglaonema
Aglaonema or Chinese evergreen is the simplest domestic plant, because it grows well in houses and low light places. The best thing of this plant is that it eliminates more toxins.
