Indoor Air Quality – It’s Importance & Dangers.

“Indoor Air Quality” is something which has been ignored by our society for a very long time. Now, when mainstream media has brought this topic into the spotlight people have started to pay some attention to it.

What is Indoor Air Quality…??                            What is indoor air air quality

Quality of Air within homes, buildings, and structures are generally considered as Indoor Air. Air Quality is generally decided by checking the number of suspended particles in the air, biological contaminants, and chemical contaminants.

Indoor Air is generally considered as not to less polluted than the outdoor air, but that is not true in all the cases.

Several studies have shown that indoor air, in fact, is 2-5 times more polluted than the outdoor air. When we think about air pollution we imagine a big factory releasing huge smoke from its chimney, Vehicles releasing smoke from their exhaust on traffic signal and so on, but there is probably more polluted air within our house than the outside.

Importance of Indoor Air.

As Nowadays we spend significantly more time indoors so maintaining good air quality is crucial. Especially for children as they spend 90% of their time indoors.

Children are more active and perform more physical activity compared to an average adult, so children are likely to breathe more air in a given time as compared to adults.

Types of Contaminants.

As there are different types of contaminants, we have divided them into 3 main categories.

1) Biological Contaminants.

2) Chemical Contaminants

3) Solid/Liquid Suspended Particles.

Let’s See What are these,

1) Biological Contaminants:-  indoor biological contaminants

Biological Contaminants are Bacteria, Fungi, Viruses, Dust mites, Animal Dandrum. These are Biological Contaminants, can be controlled by cleaning the house regularly, fixing spots where moisture accumulates etc. Biological Contaminants are dangerous but their frequency of occurrence is low if take precaution.

2) Chemical Contaminants:- 

Chemical in cigarette smoke indoor iar pollution

Volatile Organic Compounds (VOC’s) are organic chemicals. They include both naturally occurring chemical components and man-made chemical components, It includes tobacco smoke, chemicals used in wall pains, some upholstery. Furniture polish, floor carpet, and different cleaning and consumer products have chemicals in them.

This Chemical Contamination can greatly be reduced by avoiding indoor smoking habits, choosing chemical free paints, upholstery, carpet, and buying consumer products which are environment-friendly.

3) Solid/Liquid Suspended Particles:- 

suspended liquid particles in the air toxic

These are very tiny particles (7-10) nm which are light enough so they can suspend in the air freely. These suspended particles have more potential to get inside of our body very easily even if we are several feet away from the contaminant source.

Suspended Particles are generally come inside of the house from pets, perfume sprays, outside air carrying dirt, dirty shoes, and their frequency is much higher than other types of contaminants, hence they are much more difficult to deal with.

What Are The Dangers of Breathing Polluted Air…??

1) Short Term Effects.

2) Long Term Effects.


1) Short Term Effects:-                                            headache due to inhaling toxic indoor air

Headaches, Coughing, Sneezing, Watery Eyes, Fatigue, Dizziness, Respiratory Problems etc. These symptoms can be seen after just coming in contact with polluted air.

Usually, the Short Term Symptoms are ignored by many, but over the time these Symptoms turn into Long term Effects, discussed below.

2) Long Term Effects:-

Longer Exposure to the polluted air results into some serious illnesses like,

1) Asthma

2) Severe Lung Disease

3) Eye injury

4) Weight Gain

5) Depression

6) Autoimmune Diseases.

Let’s See how These Illnesses occur due to Polluted Air.

1) Asthma:-                                                                        Asthma due to inhaling polluted indoor air

The World Health Organization (WHO) estimated that 20-30 percent of all the respiratory Diseases are the result of Ambient and Indoor Air Pollution. As Respiratory pathway is a key passage for pollutants to enter in our body.

By Ignoring the Importance of Indoor Air Quality, More than 20 Million Adults and 6 Million Children are Affected by Asthma.

2) Severe Lung Disease:-                                                              Severe lung disease due to indoor air pollution

An article publishes by Physicians For Social Responsibility strongly suggest that Long Term Exposure to the polluted air is one of the causes of Lung Cancer.

Chronic Obstructive Pulmonary Disease (COPD) is strongly linked to Indoor Air. Damage to the lung causes COPD. There are millions of tiny particles in the air called “Irritants”

Damage to the lungs can occur in 2 ways,

1) By Inhaling Small Amount of Irritant Over Longer Period of Time.

2) By Inhaling Larger Amount of Irritant Over Shorter Period of Time.

So maintaining Indoor Air Quality is very Crucial for keeping our Lungs Healthy.

3) Eye Injury:-                                                                                      Eye irritation due to indoor air pollution

We know that ‘Eyes’ are one of the most important and fragile parts of our body, but it is also very vulnerable against suspended air particles called ‘Irritants’.

As Discussed earlier, Tiny particles are suspended in the air and some of them do have very sharp tiny edges, so whenever these tiny particles Enter into our eyes a feeling of itching occurs. For this itching we rub our eyelids, using fingers. This leads to rubbing effect between our eyeball, irritant particle and with our eyelid.

Now whenever such irritant enters in our eye we do the same thing of rubbing, but beware, doing this again and again over a longer period of time can damage your eye and could lead to even partial Blindness.

4) Weight Gain:-                                                                    new study found that Weight gain due to inhaling polluted indoor air

Can You Believe It…?? You must be thinking, how Weight Gain could be related to the Polluted Indoor Air…??

Here is the truth, A Study Published in The Journal of Federation of American Society For Experimental Biology found that when 2 Groups of rat fed the same diet, but in different Indoor Air Environment, showed surprising results

The group which breathed in more Polluted Indoor Air, gain more weight than the group who breathed in a Clean and Filtered Air.

This Study shows how our body responds when we breathe polluted air and changes the natural way our metabolism works.

5) Depression:-                                                                      Depression can occur due to inhaling toxic indoor air

As many as 8 out of 10 Analyzed research shows a significant relation between Depression and Polluted Air on Long Term Exposure.

A Study Done by The Yale University of Public Health found as well that, Increase in Air Pollution was Linked to the Increase in the Levels of Depression.

6) Auto-Immune Disease:-                                                            Autoimmune disease due to polluted indoor air

Nowadays, Diagnosis of Auto-Immune Disease has Increased dramatically. In Auto-Immune Disease Body’s Own Immune System Attacks its own body organs.

One Canadian Study Shows Increase in The Cases of Auto-Immune Disease could be Related to the Increase in Air Pollution.

Another Study Shows Solid Particles from the Diesel Engine increases Inflammation in the Rheumatoid Arthritis Patients. Such Solid Particles are suspended in air and, could end up inside of our homes.

  1. That’s a great article and important message, I think how to prevent air pollution in the home is very important, thank you for this article, I will share this to all of my friends!

  2. This is an informative article; I know air pollution is dangerous, but I ignore it always. After I know that short term and long term effects, I will turn on my air purifier every day. Thank you for sharing!

  3. Nicely written article. Airborne allergies are something my nephew deals with. Are you familiar at all with negative ion air cleaners? What’s your opinion on them?

    1. Yes, of course, Negative Ion Air Purifiers works very well. they are also efficient in catching airborne particles and making them heavy enough so they would fall on the floor. The catch here is there is some study showing some health benefits of Ionic Air purifier but some Ionic purifiers produce Ozone during its working.
      So I would say it’s up to the consumer, if they don’t mind going extra mile for removing the little ozone produced by Ionic Air Purifier from their house by some means, then Ionic Air Purifiers are The Best option for them.

  4. What a great and insightful article you wrote. I never thought of Air Quality nor Its Importance & Dangers but now I know better thanks to you and your post. I will definitely put it into consideration from henceforth and come back here for more insightful contents.
    Thanks for sharing!

    1. Thanks, David for reading my article, If you have any doubt or just want any advice related to Indoor Air & Air purifier please ask…I’m Happy to help you…!!

      have a good Day.

  5. Cannot wait until warmer weather and opening the windows and let the house breathe a little. I showed my son the other day with a flashlight the dust that comes off his bed when he hits it with his hand. He was amazed at the amount of stuff floating around in the air.
    Do you think having the windows open at least once a week helps with indoor air quality. I do not have an air purifier, I do clean daily to try to keep dust down. I have an electronic air filter on the HVAC system, do you think they are worth the extra cost to keep particles out of the air.

    1. Very Good question John…I’m Glad you Asked,

      Yes, It definitely helps to open windows for improving Indoor Air Quality, I would even suggest to open them a couple of times a week. As studies have shown that indoor air is 2-5 times more polluted than outdoor air.

      The thing is Electronic ( also called Electrostatic) Air Purifiers don’t even come close to the filtration power of a High-Quality Allergen filter like Honeywell or Dyson. Let me tell you how

      1)The electronic air purifiers work on the principle of Electrostatics, as dust particles pass through the first layer of electric filter those particles get positively charged due to friction between the filter & air. These charged particles end up sticking to other particles in the filter thus trapping them inside the filter.

      2)these filters can collect only small and lighter particles, but what about the larger and heavy particles, molds and spores…??
      Electric filters cannot purify these and it certainly cannot get rid of the odor.

      3) As these filters of electric purifier sit inside of your air ducts, after some time you will notice an accumulation of dust particles inside of your duct, As these dust particles are charged they tend to stick to the surface of the duct & it makes very difficult to clean them.

      4) Over time the dust accumulated in the filter will block the Airflow inside of your house, making your Air Conditioning system to work even harder resulting in increased electricity bill and higher wear of air conditioning part.

      The HEPA filter can catch the particles as small as 0.3 microns and when used along with activated charcoal filter it even takes care of the odor.

      I personally see only 1 benefit of using Electric Air Purifier that we can wash them and reuse them again and again, but there is a catch, When we wash those filters we end up cleaning only front 1-2 layers of filter and these filters generally have 8-10 layers of filtration so the layers remained unwashed, are perfect place for growth of molds & mildew.

      So, I would Recommend buying a conventional Air Purifier which is far more effective in Purifying Air & if you have someone in your house who is suffering from asthma or any airborne allergies you should definitely buy a Good quality air purifier right away.

      I am about to write an article related to Electric Air Purifiers, so stay tuned.

      I hope you are satisfied with my answer If You want to ask anything related to this topic feel free to ask any time.
