See 11 Species to Inspire You

Per Essay

It is nothing new for anyone that plants and trees function as a lung for the planet. They inspire toxic gases and release oxygen into the atmosphere, contributing immensely to air quality.

But what you may not know is that you can have plants that purify the air inside your home. That’s right! You don’t have to live in the middle of the forest or surrounded by a large green mass to breathe fresh air.

Believe me: a single plant within each environment is enough to filter and clean much of the chemical compounds that are suspended in the air.

Great news, isn’t it? So let’s check which plants purify the air and find out how you can use them indoors.

Types of pollutants most common indoors


Those who live in big cities need to deal with pollution both outside and inside the home. But it’s not just the smoke and toxic gases emitted by vehicles that come in through the window.

There are other types of pollutants equally dangerous to human health, most of which come mainly from cleaning products and insecticides. Check out the most common pollutants found in homes:


Xylene is a chemical compound derived from petroleum, more specifically from a compound known as benzene.

This substance can be found in cigarette smoke, varnishes and gasoline. Exposure to xylene can cause throat irritation, headaches, dizziness, lack of concentration and mental confusion.


Ammonia is present in several products, from hair dyes to glass cleaners, floor waxes and even certain types of detergent and fabric softener.

Exposure to ammonia can cause eye and throat irritation, as well as coughing.


Formaldehyde is popularly known as formaldehyde when presented in liquid form. Its main function is to prevent the growth of microorganisms, so it is widely used as a preservative.

Formaldehyde can be found in paints, solvents, varnishes, cigarettes, disinfectants, fungicides, germicides and nail polishes.

With a strong and irritating smell to the mucous membranes, exposure to formaldehyde can cause irritation in the eyes, throat and nose, in addition to headache, nausea, swelling of the larynx and lungs.

According to data from the International Agency for Research on Cancer (IARC), formaldehyde is proven to be a carcinogenic compound.


Benzene is another very toxic substance and one way or another is always present inside the home.

This is because benzene is used to manufacture numerous cleaning products, such as detergents, furniture polish and polishing waxes. Benzene is still found in glues, solvents, paints, car lubricants and in pesticides and insecticides.

Exposure to benzene can cause headache, dizziness, mental confusion, drowsiness, eye irritation and increased heart rate.


Trichlorethylene is mainly present in paints, solvents and varnishes. Exposure to this chemical can lead to nausea, vomiting, headaches and dizziness. In more severe cases, trichlorethylene can cause drowsiness and even coma.


Toluene is a petroleum derivative popularly known as “shoemaker’s glue”.

Glues of various types, solvents and preservatives are produced from this substance.

Toluene is also found in cleaning products, cigarettes, removers, pesticides and insecticides.

Toluene is generally absorbed by the lung through inhalation.

In such cases, the most common symptoms are tiredness, mental confusion, loss of memory, nausea, loss of appetite, vision and hearing.

However, these symptoms tend to disappear when exposure to the product ends.
