6 Ways Indoor Air Pollution Affects Your Health

6 Ways Indoor Air Pollution Affects Health

Could the air you are breathing in be harmful to your health and lead to lasting health effects? It is easy to forget about air as a potential risk factor for our health because we can’t tangibly see air to consider its power. Most Americans spend about 90% of their time indoors. Additionally, indoor air pollution is typically much worse than outdoor air quality unless you take steps to filter it properly. Indoor air pollution effects your health in more ways than you know.

When it comes to overall health, the quality of the air you are breathing is something to really consider.  Out of the 90% of time that most people spend indoors, 65% of that is actually in your own home. You may be thinking that your home is safe and free of toxic air pollution but you may want to think again.

Sources of Indoor Air Pollution

Many household products contain toxic chemicals that can turn into air pollutants in your personal environment. Most indoor air pollution originates from sources that release gases or particles into the air. Candles, air fresheners, cleaning products and other household items can be potential culprits of air pollutants in your home. The products in your home, aren’t the only compromising aspects of your indoor air quality.

Poor ventilation in your home can also taint your indoor air quality, without the release of air pollutants in your home from proper ventilation an accumulation of pollutants will make home in your air. In recent years, homes have been constructed to be well-sealed fortresses to help reduce utility expenses. However, a trade-off occurs when you then compromise the quality of your indoor air which can then lead to potential health issues in the future from long-term exposure.

Health Effects of Air Pollution

Indoor air pollution was ranked as one of the top five environmental risks to public health according to the United States Environmental Protection Agency (1). Scary, isn’t it? The effects that air pollutants and poor indoor air quality can have on our health is a very imminent threat to our overall health.

The severity of the potential health effects from indoor air quality depends on a few things, specifically how polluted your indoor air really is and how long you have been exposed to the hazardous pollution. Symptoms that usually are acquired from indoor air pollution can range from coughing, sneezing, watery eyes, fatigue, dizziness, headaches, and upper respiratory congestion.

Although, these short-term effects may not sound too threatening the inherent long-term effects that can affect you have the risk of being quite detrimental to your health. Long-term effects can range from weight gain, depression, allergies, autoimmune disease, cardiovascular disease or even asthma.

Indoor Air Pollution

Weight Gain

Have you been packing on the pounds but just can’t understand the sudden fluctuation on the scale? You may be following your diet and eating all the right things but the pounds keep coming on for no reason. Could your indoor air pollution play a role in this sudden and unexpected weight gain?

Simply put, yes, it is possible that your compromised indoor air could be contributing to the elevated number you see on the scale. Many things can be an added factor to weight gain including metabolism, genetics, and shockingly enough the air you breathe in every day.

A study published in the Journal of the Federation of American Societies for Experimental Biology found that two groups of rats who were served the same diet but in two different indoor air environments had surprising results. The group of rats that were exposed to and breathed in more polluted air gained more weight in comparison to the group who was exposed and breathing in clean, filtered air (2). These results can implicate the same unnerving outcomes for humans that are also exposed to indoor air pollution.


Depression is a leading cause of disability worldwide, according to The World Health Organization. In recent years depression has become a serious health condition that many people suffer from that can debilitate their quality of life. Depression is commonly associated with genetics or a life event that can progress this state, but what if the air you breathe everyday contributes to this condition?

The potential risk factor of depression can be hard to pinpoint, with research having a strong focus on air pollution that can magnify the intensity of depressive symptoms. As many as 8 out of 10 analyzed research shows a significant correlation between long-term exposure to air pollution and depression (3). This could be potentially due to the inflammatory response that being exposed to environmental toxicity has on the body.

A study conducted by the Yale School of Public Health found as well that an increase in air pollution was linked with an increase in higher levels of depression (4). Getting rid of indoor air pollution can possibly be a method of aiding in the severity of your depression and help to aid in the betterment of your overall health.


The World Health Organization estimated that 20 percent to 30 percent of all respiratory diseases are a result of ambient and indoor air pollution (5). This would stand to reason since inhalation is the key passageway for air pollutants and affects the respiratory system. More than 18 million adults and 6 million children as of 2012, suffer from asthma.

Could this increasing trend be the result of poor indoor air quality? Asthma, a respiratory disease, can be severely impacted by poor indoor air quality and can be caused by breathing in toxic air pollutants in your environment. Air pollutants are small particles that find their way into your air, and taint the air you breathe which can than lead to potential respiratory issues.

Indoor air pollutants and allergens play a major role in triggering asthma attacks, as well as eliciting asthma symptoms or just making a person’s asthma worse in general.


Allergies come around as allergens find their way into your air, as one in five Americans will likely experience allergy-related illnesses at some point in their lives, and indoor allergens are predicted to be the key component for many, according to the Institute of Medicine (6). The pollutants in your home’s air can trigger the onset of allergy symptoms such as skin rash, headaches, sneezing, runny nose, swelling, and fatigue.

When pollen is in the air it is usually when allergies come roaring their ugly head in full force. In recent years as the temperature drops in the winter and we shelter ourselves indoors, allergies have been steadily increasing as air pollutants flood your home’s air. Not only does your home contain indoor air pollutants that have been brought by various household items such as the cleaning products you use in your home, but your home’s air also contains outdoor allergens that force their way into your tightly ventilated home.

Your home’s HVAC filter can play a critical role in trying to eliminate allergens from your personal indoor environment. Most HVAC filters lack the ability to capture and eliminate a broad spectrum of chemicals and odors that come into contact with the filter, and these filters tend to get used fairly quickly, meaning you are changing them more frequently than you really should.

With the EnviroKlenz HVAC filter you can effectively remove allergens and chemicals in your air, which in turn will help to minimize the impact allergies have on you all year round.

Autoimmune Diseases

Autoimmune diseases have recently come to light as more and more are diagnosed each year with these debilitating diseases. Autoimmune diseases are characterized as an immune response which in turns leads to the destruction of the body’s own tissues and organs. A new Canadian study suggests that the recent increase in diagnoses of autoimmune diseases can be attributed to air pollution.

Another study found that one category of particulate matter, diesel exhaust nanoparticles showed to have an inflammatory response on the cells of those who suffer from systematic autoimmune rheumatic disease (7).

Also, fine particulate exposure was correlated with an inherent risk of systematic autoimmune diseases (8). Someone suffering from autoimmune disease, their body treats their organs and tissues as invaders that the body tries to kill off, and any environmental trigger can enact this response, making air pollutants a danger to those with an autoimmune disease.

Cardiovascular Disease

Every 40 seconds in the United States somebody dies from cardiovascular disease, according to the American Heart Association. This alarming statistic sheds light on the precarious and dangerous condition of cardiovascular disease. What can attribute to this statistic? Indoor air quality could be just one of the potential contributing factors to cardiovascular disease.

The EPA has conducted research and studies to try to progress our understanding of the possible link between air pollution and heart health. Findings have concluded that oxidative imbalances occur, and when you inhale air pollutants it can negatively affect your cardiovascular system (9). Essentially, increased environmental air pollution results an increase in oxidative stress and inflammation at the cellular level of the body which leads to an increased risk of arterial calcification.

Pollution particles smaller than 2.5 microns are the main cause for concern says researchers. Due to the fine size of these particles they aren’t easily partitioned and can become more easily digested in the human body, which than can lead to irritation of the lungs and blood vessels around the heart (10, 11).

How to Prevent Air Pollution in Your Home

Are you ready to go through your home now and decontaminate for possible pollutant culprits? Pollutants can enter into your home in several ways either originating in your home or sneaking in through your clothes or other items that collect the pollutants, such as pollen and allergens.

Indoor pollutants can come from a variation of things including pet dander from your animal, to cleaning products, or even cooking fumes. Preventing air pollution in your home is possible though. You can successfully combat and minimize the amount of air pollutants in your home by simply treating the air in your home.

Purify Your Indoor Air

Treating your air is the key in eliminating air pollution in your home. What exactly is the best way to treat the air in your home without releasing more chemicals into your air? Buying a home air purifier system can help to drastically improve the quality of the air in your home. The EnviroKlenz Mobile Air System has a two-stage filtration, a patented earth mineral technology air cartridge and a hospital grade HEPA filter. It is completely safe to use and non-toxic.

The technology works on a broad spectrum of chemicals and odors to capture and neutralize them at the source. Unlike many other air purification systems that take in chemicals and re-releases them back into the environment, acting counterproductively. Make sure to do your research before purchasing an air purifier for your home.

Indoor air quality can be a very serious issue for many people, however the attention it gets can be less than what is necessary. With the recent studies that have found potential links to health ailments like weight gain, depression, allergies, autoimmune disease, cardiovascular disease and even asthma, air quality should be at the forefront of people’s minds. Working towards protecting yourself and your home from poor indoor air quality and air pollutants can help you to better defend yourself against potential hazardous health ailments.

4 Ways to Improve Indoor Air Quality

It is vital that we look to for ways to improve indoor air quality.  A total of 10,000 liters of air enters your lungs every day, with the potential of breathing in harmful toxins being a very imminent threat to your health. The Global Burden of Disease (GBD) found that exposure to air pollution and particulate material was ranked as one of the top 10 risk factors for disease globally (1).

We tend to deem that air pollution is prominent in our outdoor environment due to high levels of chemicals produced in the environment by external factors such as cars and factories. Although, these factors do indeed produce a copious amount of chemicals, the environment that poses the biggest risk to you is undeniably your personal indoor environment. Finding ways to improve indoor air quality can be one of the biggest things you do for your health.

Toxic Chemicals in Our Home

Toxic chemicals can be in abundance in your home, without you even being aware. The U.S. Environmental Protection Agency (EPA) affirmed this by stating that indoor air is 2 to 5 times more polluted than outdoor air (2). Thus, discovering that indoor air is for the vast majority of people to be the unhealthiest air they breathe in during their day.

Chemicals are all around, surrounding you in the most inconspicuous of household items from your everyday laundry detergent to chemicals used on your furniture in the extensive manufacturing process. In recent years, a strong link between indoor air pollution and health related ailments has developed, therefore forming an undertaking to educate people on the impact indoor air pollution can have on your overall health.

Air Quality and Health

Indoor air quality has become a recent focus for many in the health profession, as research has shown a significant correlation to indoor air quality and certain health conditions such as respiratory, cardiovascular and autoimmune diseases. Air pollutants have several factors that impact their severity on your health including their size, shape, and the amount of time you are exposed to the pollutant (3).

Particulate matter can be a mixture of particles that can unfavorably affect somebody’s health, with the size of the particulate matter being the biggest determinant of causing possible health-related problems. To control particulate matter in your home, utilizing an effective HVAC filter for chemical odors and VOC removal can also help to remove not only particles from your indoor air but also bacteria from the environment. Particulate removal can aid drastically in improving your indoor air quality and helping to improve your overall health.

Health Effects of Indoor Air Pollution

Indoor air pollutants can impact your health and lead to negative health effects that can lead to severe symptoms and even disease. Air pollutants can affect certain areas of the body such as the respiratory system, immune system, skin and mucus membranes, cardiovascular system, liver, kidneys, and gastrointestinal (4).

The potential impact that indoor air pollution can have is cause for concern for many people. Keeping an eye out on possible symptoms stemming from indoor air pollution can help you to have a better understanding of when indoor air pollution is effecting your health. The symptoms to look out for include:

Ways to Improve Indoor Air Quality

Whatever is in your home’s air ends up in your body so finding ways to make it as clean as possible is the first step in shielding your health.  Contaminant and toxins can be in the most unsuspecting places in your home, according to German chemist Michael Braungart he found that nearly everything we use, from our furniture to our cleaners, releases small particles or gases that are harmful to be ingesting on a regular basis (5).

Carpets, upholstery, wood products, and cleaning products can emit volatile organic compounds (VOCs) into your environment. You may be wondering how you can protect not only yourself but your home from these potentially dangerous chemicals. The steps below are to help you in the pursuit of improving your indoor air quality in your home.

Using Non-Toxic Cleaning Ingredients in Your House

Cleaning products can be a big contributor to indoor air pollution in your personal environment. To think that you are actually trying to help minimize dirt and pollutants in your home by cleaning. And then unknowingly contributing more pollutants in your environment, making your mission counterproductive.

Recent studies have connected cleaning sprays with asthma development, making the concern of cleaning supplies in your environment a possible fear. Most cleaning products contain terpene, hydrocarbons, terpene alcohols, and other related unsaturated compounds.

Natural Cleaning Products

These chemicals, specifically terpenes, can react with ozone to form a variation of secondary pollutants including formaldehyde and ultrafine particles (6). The pollutants that are then released into your air can be compromising the quality of the air in your home.

For many of us we have our go-to products that we always use during our cleaning process, but looking at the ingredients listed on your products can help you make better decisions when purchasing cleaning supplies in the future. I recommend switching to non-toxic, natural cleaning products to help you drastically increase the quality of the air in your personal environment, and help to minimize the potential release of added pollutants in your home.

Substitute Your Air Freshener for Essential Oils

Another major air pollutant that pollutes your home’s air quality can be air fresheners. Air fresheners, like other cleaning sprays, contain similar chemicals and thus have the same chemical reactions, producing secondary pollutants in the air of your home. These pollutants can have potentially serious health impacts including sensory irritation, respiratory symptoms, dysfunction of the lungs, and cause damage to the central nervous system (7).

Air fresheners over the past years has been deemed a source of various volatile organic compounds (VOCs) found in indoor environments which can be the leading source of these health impacts produced by air freshening products. So, how can you get rid of the odors that are stuck in your home without the use of air fresheners?

An ideal substitute in lieu of toxic air fresheners can be using essential oils in your home. Essential oils are natural organic compounds that are extracted from plants and contain a vast amount of healing properties. Using essential oils to freshen your personal environment rather than air fresheners will help you to avoid polluting your home’s air with harmful chemicals and airborne irritants.

Home Hygiene

Maintaining proper hygiene helps in the mitigation of bacteria and germs that collect on surfaces of your personal environment. Home hygiene isn’t necessarily the act of cleaning but more so a practice that should be implemented in your everyday routine. Without home hygiene, bacteria and viruses can begin to populate your indoor air and lead to the development of infectious diseases.

Recent studies have suggested that a promotion of improved hygiene in the home could have a significant impact in reducing infectious diseases (8). Wiping down surfaces can help in the effort to minimize bacteria and viruses in your home, as well as making sure you yourself are taking proper hygiene steps such as washing your hands frequently. By practicing good environmental hygiene practices and working towards eliminating bacteria and viruses at home you can help improve the overall air quality and your health long-term.

For a great natural all-purpose cleaner, try combining the following: 1/2 Cup vinegar, 5 cups of water, 5 drops each of wild orange, clove, lemon, tea tree, and rosemary. This can be used to naturally clean non-porous surfaces in the bathroom and kitchen.

Home Air Purifier

Air pollutants can be released from an abundance of surfaces and items in your home. In today’s homes, ventilation is very limited to help with lower cost utilities but with little ventilation leads to a trapping of pollutants in your home. These pollutants can significantly impact your health and cause health related illnesses such as allergies, asthma, and respiratory diseases. Several allergists advocate air purifiers to their patients to help reduce health symptoms and increase the quality of air in the personal environment.

Dr. Daryl R. Altman, an allergist at the Joseph P. Addabbo Family Health Center in Queens, said purifiers are part of the mission against allergens like dust and pollen that affect your indoor air quality (9). Other doctors, also recommend air purifiers to help with the elimination of airborne allergens and pollutants, such as Dr. Nicolas Busaba, an ear, nose, and throat doctor at Harvard-affiliated Massachusetts Eye and Ear Infirmary (10). Dr. Busaba recommends an air purifier with a high efficiency particulate air (HEPA) filters to capture particles in the air.

EnviroKlenz Air Filtration System

The EnviroKlenz Mobile Air System utilizes not only a HEPA grade filter but also uses a two-stage filtration with their patented earth mineral technology. Effectively removing not only particulate matter in your indoor air environment but also toxins, chemicals, and strange odors in the air to improve the quality of the air you are breathing.

Toxins and chemicals in your indoor environment have the potential to be quite hazardous to your health. Implementing these methods to improve your personal environments indoor air quality can help you in the pursuit to aid in the betterment of your overall health.
