Your home should be free from Air Pollution

You get home after a long day at work and to get away from all that is unwanted - noise, people, work, traffic, smog, that annoying neighbor, unwanted distractions, the extreme cold or the extreme heat, and the list goes on and on.

Never do you ever come home thinking that the air environment in your home may be unhealthy! After all, all the windows and doors are shut and there is nothing in your home that should be polluting the air. In-fact you have your air conditioning running on a hot summer day and you just changed the air filter on it. So, air is the last thing on your mind when you get home and your home should be free from air pollution.

You should feel healthy in your home

Irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue

After going to bed, you wake up early in the morning with this excruciating headache, your chest feels like an elephant is sitting on it and you are having trouble breathing. Instead of jumping out of bed and working on that art project you have been wanting to finish up, your fatigue body wants to simply stay in bed! The first thought that comes to your mind is that you may have caught the flu. Perhaps you did but perhaps you are exhibiting the typical symptoms associated with excessive exposure to Indoor Air Pollution. According to the Environmental Protection Agency (EPA), health impacts may be experienced soon after exposure or years later. These symptoms often include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Often these symptoms are confused with flu because of how similar they are.

Discomfort in your home

Indoor Air Pollution Facts

Now here is an interesting fact; According to the EPA, our indoor environment is twoto five times more toxic than our outdoor environment, and in some cases, the air measurements indoors could be 100 times more polluted!

According to World Health Organization (WHO), 4.3 million people a year die from the exposure to household air pollution. Perhaps its time to take some action!

Indoor air pollutants play a significant role in triggering asthma attacks according to EPA. Triggers are things that can cause asthma symptoms, an episode or attack or make asthma worse.

Some of the worst health impacts based on research by WHO, prolong or high exposure to indoor air pollution may results in health issues including pneumonia, stroke, ischaemic heart disease, chronic obstructive pulmonary disease (COPD), and lung cancer.

Steps to reduce your exposure to air pollution

So what does all of this mean? There are specific steps you can take to reduce the levels of exposure - you can do this with some simple changes in your indoor environment, your lifestyle and with some help from innovative nanotechnology. Yes the world of Internet of Things (IoT) and the advancement of nano sensors is slowly but surely making its way to your home. I am sure for many of you, it can't come soon enough.

For me, its important to know what's in the air and I compare it to reviewing the ingredients label on packaged food every time. Just like wanting to eat healthy, I would like to breathe in an environment that I know is healthy for my body.

What is Nanotechnology

Nanotechnology deals with materials at nano-scale or 100 nanometers (nm) or less. One meter is equivalent to 1,000,000,000 nm.

  • A sheet of paper is about 100,000 nm thick
  • There are 25M nanometers per inch
  • A Strand of human DNA is 2.5 nm in diameter
  • A human hair is approximately 100,000 nm wide

An example of nanotechnology structure

Nanotechnology Defined

According to the U.S. National Nantechnology Initiatve (NNI), Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers (nm), where unique phenomena enable novel applications. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. For example, carbon nanotubes are used in various nanotechnology applications including fluid sensing technologies. Carbon nanotubes may be between 1nm to 2nm in width.

Nano Gas Sensor

Nano gas sensors are currently being developed to be very small (as small as 5mm by 5mm), use extremely low power, and can target and detect multiple gases in the environment simultaneously. These features are necessary to be able to pick out a very specific gas that is harmful to our health in an indoor environment where there could easily be over 200 gases and other volatile organic compounds (VOCs).

The technology advancement in nano sensors and with the Internet of Things (IoT), more devices in your home will now have the ability to incorporate nano gas sensors into their product lines. For example, your smoke detector will soon be able to detect not only smoke but also other gases that may be harmful in your indoor environment such as a methane gas leak, or formaldehyde.


In conclusion, as urban development continues to expand all around us, the impacts of air pollution will continue to impact our health. Indoor air pollution can be the result of many airborne toxins that get trapped in your home and these toxins may be a result of a faulty heating system or may be brought into your home when you built the new wooden flooring.

Knowing what's in the air your breathe at home can make all the difference between feeling great or miserable and until recently the only way to know that the air is not healthy would have been indicated by the way you felt. With recent advancements in nano innovation, nano gas sensors capable of detecting multiple harmful airborne toxins will be able to alert you and provide specific actions you can take before it becomes a health issue for you and your family.

      No one likes being poisoned. I would buy it if I have the cash. I mean, the air quality where I am at is not the best, so I would rather have it than not have it.

      Anything to avoid a trip to the Emergency room for my daughter that suffers from severe pollution related allergies. Can't wait for any help!

      Thanks to all that have sent me emails and also shared your comments here. I appreciate your candid feedback and can appreciate your concerns about technology taking over your lives if you want yet another tech in your home. The key to all of this is getting educated and then to decide the balance of technology as it relates to improving health. For those of you excited to know what's in the air and how it's impacting your health, stay tuned as several companies are working to get this tech out to the consumers.

      70% Yes – I would love to have it

      20% Maybe – Not sure how it can help

      10% No – I don’t need another sensor in the hous

      I think this is a great idea - hope it will show up in stores soon. I live close to the freeway and every time I open windows in the am during traffic hours, I can feel the difference in the way i am able to breathe. Just don't know what is causing it though. It would be great to finally understand what is causing my heavy breathing. Thanks for the information!

      I don't need another sensor in the house at this time but it's good to know that this is out there if I change my mind.

      The more I think about it, the more I can see how positive of an impact something like this could have. There are so many stories about families that barely make it out of their homes because of carbon monoxide leaks, and as a result many homes, apartments, schools, and daycare centers now have detectors for it.

      But from the sound of this, this new thing would take those carbon monoxide detectors one step farther. My son has had moderate asthma his whole life and we do so much to keep the air he breathes clean, but it is never enough. If we had a way to know that the air quality in our home was poor, then we could take preventative steps prior to an attack. We could make sure he is doing calm activities that day. Or give him his medicine prior to an attack even starting to stop it in its tracks. There have been so many trips to the emergency room that could have been prevented had he just used his inhaler sooner. It sounds like this "technology advancement" could help not only my son, but many others in similar situations, live a much more comfortable life.

      I know I can speak for many when I say I can not wait to see where this technology goes.

      I can totally relate to this whole story. I feel like waking up is 50/50 chance of feeling like I have the flu. It would be so great if I could just check something like a thermostat in the mornings to know what my air quality is.
