Indoor air quality plays a major role in the health and safety of a home. Pollution is not exclusive to the outdoors, as both outdoor and indoor air can be compromised by pollution. Indoor air can be polluted by airborne chemicals, toxins, and other nasty particulates that can trigger allergies and other health reactions.
It is for this reason that every home should be equipped with an air quality monitor. If you are someone who travels frequently, it is important to have an air quality monitor on hand to ensure that you are residing in a safe atmosphere with good indoor air quality.
The unfortunate reality is that exposure to poor air quality for extended periods of time can have detrimental and long term health effects. It’s important to find the best air quality monitor for your home or your unique lifestyle to maintain your health.

Air Quality Monitor Buying Guide
It’s important to never underestimate the invisible pollutants in the air that you breathe. The problem is, air quality is invisible to the eye. This is why there are air quality monitors that are designed to detect airborne pollutant materials like harmful chemicals, gasses, and temperature and humidity levels.
While not every air quality monitor is made equal, it’s important to find the right air quality monitor for your home to ensure that the air you’re breathing indoors is not detrimental to your health in fact, some air quality monitors even assess outdoor air quality so that you can avoid highly polluted areas.
Why to Monitor Your Air
There are many reasons why homeowners and business owners of all kinds will want to assess the quality of air they are breathing on a daily basis.
The reality is that your indoor air can be packed with allergens that, as a result, can trigger allergies. Common allergens in indoor air include dust mites, mold, and pet dander — most of which can be detected by an air quality monitor . Once you identify the presence of these allergens in your home, you can make some changes in your habits, filters, and cleaning practices to rectify this situation. For example, you may identify that your home requires a HEPA air purifier to help purify your air.
Allergens like those listed above as well as other factors like fragrances and volatile organic chemicals can make it harder for people to breathe — this is because breathing in polluted indoor air makes it that much harder for a person with asthma to breathe regularly.
Those living in polluted indoor air can have a spectrum of health impacts ranging from headaches, and fatigue, to coughing, sneezing, congestion and shortness of breath. Harmful particulates are also known to cause irritation of the throat, nose, eyes, and skin . This is why there are guidelines for indoor air quality .
The reality is that particulates and chemicals are not the only things that can compromise your home’s indoor air quality. Temperature and humidity also play a major role as air needs to be effectively ventilated to combat pollutants and to ensure the circulation of fresh air.
Many air quality monitors (albeit not all) will read humidity and temperature levels to ensure that your ventilation is working properly and to alert you of any high or low levels to be cautious of.
The reality is that while humidity and polluted air can be harmful to your health, high levels of humidity can cause moisture and as a result develop mold, and compromise the structural integrity of your home .
What to Monitor in Your Indoor Air
CO2 (Carbon Dioxide)
Carbon Dioxide is an invisible gas as it is both colourless and tasteless. This gas weighs more than air, and is actually not toxic by nature. The reality is that there are standard levels of CO2 in outdoor air, but this gas can be suffocating if it exceeds the volume of oxygen in a person’s brain. This unsafe ratio can result in headache, tinnitus, respiratory disorder, and increase blood pressure .
Other harmful gasses that can be measured by an air quality monitor includes smoke, fog, and carbon monoxide.
VOC (Volatile Organic Compounds)
The United States Environmental Protection Agency defines volatile organic compounds (VOCS) as compounds that “are emitted as gases from certain solids or liquids.” VOC concentrations are significantly higher indoors than outdoors due to the contained space, and include a wide range of chemicals that can have varying health impacts.
According to the Minnesota Department of Health, the most common VOCs include :
- Ethylene glycol
- Methylene chloride
VOCs can be released by a wide variety of products ranging from furniture to common household items including hair and cleaning products. Air quality monitors can help detect the presence of any of these VOCs in your indoor air.
Particulate matter refers to the solid and liquid particles that can be airborne and pollute the air. When breathed in, particulate matter can trigger allergies, make it harder to breath, and impact the heart and lungs .
Particulate matter comes in different shapes and sizes which is why some are easier to detect than others. This matter is measured and identified based on size (i.e. PM2.5). Different air quality monitors can detect particulate matter of varying sizes, and will notify the user when the particulate matter in the indoor air exceeds safe levels
While most air quality monitors detect harmful gasses, chemicals and particulates, some will also monitor humidity levels. The reality is that exceedingly high or low humidity levels can be harmful. Control humidity levels to avoid having too much humidity in your home.
According to the Government of Canada, high levels of humidity can cause mold to grow (which can have lasting health effects), and low levels can cause dryness in the air.
Consistent temperature is essential for the comfort and health of those living in a space. Ventilation and air circulation helps to regulate temperature, but it is important to detect when temperatures are inconsistent. Cold climates are dry and warm climates can cause moisture build up which, as we know, can lead to mold. Some air quality monitors will also help users to measure their temperature during the day and overnight.
