Is The Air In Your Home Polluted?

is the air in your home polluted? benefits of house plants

When we change our habits towards wellness one area of our life we often overlook is our home. We concentrate on exercise, improving out diet, balancing supplements, adopting practices like yoga or mindfulness. But often we don’t even consider the air inside our home may be highly polluted.

Causes Of Toxic Air

Building Biology  is a holistic discipline which examines and identifies irritants and hazards in residential and public structures. These include building materials, the products we use, air quality, water, biological contaminants (mould) and pest control, as well as electromagnetic fields (EMF’s) radiation (EMR) and geopathic stress.

It developed in response to a growing awareness of the impact toxic components in our immediate environment are having on our health. According to Building Biologist Nicole Biljsma  it “provides a holistic examination of the built environment and provides realistic solutions to create buildings that support mind, body and soul.”

When problems are found with the air quality within buildings the first line of attack is to eliminate the source of pollution. This may be caused by the actual building materials, furnishings, products used within the space, pest control, or cleaning methods.

Once the source of the pollution has been addressed air purifiers and filters are generally the next step taken towards achieving clean air.


Natural Remedies For Pollution In Your Home

Before you buy an expensive electric air purifier for your home consider that bringing household plants is one very simple way to improve air quality in your home.

Plants are said to be the lungs and kidneys of the building. Research at NASA’s Space Center has shown that the presence of certain indoor plants actually improves indoor air quality.

The plants are able to grab and filter common pollutants found indoors and so purify the air.

NASA has made a list of the most beneficial plants in order of their effectiveness.



Why Our Homes Are Polluted

Many of the products including carpet, fabric, wall coverings, furniture, and paints we use to furnish our homes, schools and workplaces contain highly toxic chemicals which are released into the air, creating indoor air pollution.

In 2009 the US Environmental Protection Agency stated that “The air within our homes can be seriously more polluted than the outdoor air in even the largest and most industrialized cities”.

Many newer homes are now designed to ‘seal’ in the air in order to better regulate the internal environment and reduce the use of carbon fuels for heating and cooling.

Living in these sealed homes can result in a disorder know as Sick Building Syndrome.


Sick Building Syndrome


Sick Building Syndrome is a recognised disorder which results from the build up of toxins in our environment. One in particular is formaldehyde.

It’s becoming more widespread with the increase of energy efficient buildings. These sealed buildings allow little exchange of fresh outdoor air for the stale polluted indoor air. This lads to the indoor air becoming ten times more polluted than the air outside. In developed societies we spend up to 90% of our time indoors. Therefore we are now spending most of our life in extremely toxic surroundings. Indoor air quality is quickly becoming a particularly concerning problem.

Simply introducing plants into the environment can greatly reduce these problems.

Research from the Environmental Research Laboratory of John C. Stennis Space Center has shown that rooms filled with the right plants have 50-60% fewer airborne moulds and bacteria than those without plants.

It is widely known that plants take in carbon dioxide and release oxygen. But it appears the plants can also suck toxic chemicals out of the air by absorbing the pollutants into their leaves. They then transport them to the roots where they are transformed into food.

NASA findings show that plants are able to remove up to 87% of air toxins over 24 hours.

Amazing Benefits Of House Plants

Indoor plants can bring a host of physical and mental health benefits.

Houseplants purify the air in a number of ways.

The air in environments with ducted heating dries out quickly, causing respiratory congestion and dry skin. Plants are ideal additions in these places. They balance humidity levels by maintaining the moisture levels in the air at an optimum level. This level is low enough to reduce illness and at the same time, high enough to prevent mould formation

The Norwegian University of Agriculture found indoor plants fight certain illnesses. Symptoms of the following health problems were all reduced.

  • Fatigue by 20%
  • Headache by 45%
  • Sore/dry throat by30%
  • Coughs by 40%
  • Dry facial skin by 25%

Other research has shown house plants have a psychological benefit, increasing self-esteem, improving mood, reducing stress, anxiety and depression and increasing feelings of calm, relaxation and optimism.

With their ability to impact stress levels and reduce blood pressure levels, the important role of indoor plants in a society with a rising incidence of Adrenal Fatigue  seems apparent.

Being surrounded by indoor plants can also make you think better, as they improve memory, concentration and attention, as well as boost creativity. Perhaps bringing one into you study or office will improve your productivity as well as reduce the EMR from your computer.



Best Air-Purifying House Plants

These are the top ten air-purifying plants as classified by NASA, along with their NASA rating (out of 10):

  1. The Areca Palm   8.5
  2. The Lady Palm   8.5
  3. The Bamboo Palm   8.4
  4. The Rubber Plant   8.0
  5. The Dracaena   7.8
  6. English Ivy   7.8
  7. The Dwarf Date Palm   7.8
  8. The Ficus Alii   7.7
  9. The Boston Fern   7.5
  10. The Peace Lilly   7.5

It’s said that Common English Ivy (Hedera helix) ranked sixth in the NASA list is “a fix for allergies” and Boston Fern (Nephrolepis exaltata) is the “most efficient filtering plant”.

A little research can help determine which of the recommended plants are better for your personal needs. Some may address your health problems better than others.

There are many other beneficial plants not included on this list.  Gerbera reduces levels of the chemical solvent benzene. Chrysanthemum, the extremely hardy Spider plant and Aloe, are others you could also find helpful.

For best results you need about 15 plants for a 15 square home or 140m² office to keep the air clean.

Make the motto of your home and workspace  ‘MORE GREEN – LESS STRESS’
