Understanding Indoor Air Quality Sensors

Detecting and monitoring various pollutants like volatile organic compounds (VOCs), particulate matter, and radon is the main function of indoor air quality sensors, which contribute significantly to maintaining a healthy living environment. With the rise in air pollution and the increasing awareness of its health implications, air quality monitors have become a popular choice for home and building owners looking to improve indoor air quality.

Types of Indoor Air Pollutants

Indoor air pollutants can come from various sources, both natural and man-made. Common pollutants include:

  • VOCs
  • Particulate matter
  • Radon
  • Carbon dioxide
  • Carbon monoxide

Particulate matter consists of tiny solids and liquids, such as dust, pollen, mold spores, and smoke, which can cause respiratory issues. VOCs are invisible gases emitted from materials like paint, varnishes, flooring, or textiles, with formaldehyde being the most widely recognized VOC.

Carbon monoxide is a toxic gas that can be produced in many ways. Unvented space heaters, car exhaust in closed garages and other gasoline-powered equipment in poorly ventilated areas all lead to the production of carbon monoxide. Elevated levels of carbon dioxide can lead to loss of consciousness and can be potentially fatal. A fundamental step towards managing indoor air quality and fostering a healthy indoor environment involves identifying and understanding these pollutants.

Sensor Technologies

Various sensor technologies are utilized in air quality monitors to detect different pollutants. Electrochemical sensors operate based on the principle of amperometry, generating a current proportional to the concentration of the target gas in the air. These sensors can detect pollutants such as NOx, SOx, H2S, NH3, VOCs, CO, H2S, NO, SO, and O3.

Laser estimation sensors, on the other hand, employ laser light scattering principles to measure the number and size of airborne particles. These sensors estimate the particulate matter (PM) in the air, including pollutants like ozone, by gauging the quantity of light scattered by the particles. Thus, air quality monitors use a combination of these sensor technologies to provide comprehensive information on indoor air quality.

Factors like accuracy, range of detected pollutants, and ease of use should be taken into consideration when choosing an air quality monitor for your home. Choosing a monitor that provides reliable and consistent measurements is crucial because inaccurate readings can trigger false alarms or instill a false sense of security.

Additionally, consider the specific pollutants you’re most concerned about and select a monitor that can detect those pollutants effectively.

Accuracy and Precision

Although consumer air quality monitors may not be as precise as laboratory detectors, they can still be helpful in detecting airborne particulates and toxic gases. The reliability of air quality readings on monitors is estimated to be between 70% and 85%. This means that while the monitors may not be perfect, they can still provide valuable information about your indoor air quality.

For example, the Temtop M10 Air Quality Monitor has been shown to produce PM2.5 readings that were almost identical to other monitors tested and in line with the readings from a professional-grade particle counter used as a control. Therefore, choosing an air quality monitor that strikes a balance between accuracy, precision, and affordability is crucial.  Full discloser:I have never used the Temtop monitor, so please check reviews before buying.

Additional Solutions for Better Indoor Air Quality

Air quality monitors play a significant role in helping to monitor air quality and maintain a healthy indoor environment, but considering outdoor air quality and other solutions can enhance your indoor air quality even more.

Additional methods for achieving better indoor air quality, such as air purifiers, HVAC filters, and proper ventilation, will be discussed in this section as complementary solutions.

Air Purifiers

Air purifiers are effective devices for removing pollutants from the air and improving overall indoor air quality. They work by filtering the air and eliminating pollutants using various technologies, such as HEPA filters, activated carbon filters, and UV-C light. Studies have shown that air purifiers can reduce indoor fine particle concentrations by up to 60%.

However, keep in mind that air purifiers are incapable of eliminating all pollutants from the air. By using an air purifier in conjunction with an air quality monitor, you can further improve your indoor air quality and ensure a healthier living environment.

HVAC Filters

Regularly changing your HVAC filters can help reduce airborne pollutants and maintain a healthy indoor environment. Pleated filters with a high MERV rating (Minimum Efficiency Reporting Value) of 6-12 are the most effective for filtering out harmful air particles.

Changing your HVAC filters every 30 days or less can help ensure optimal air quality. By keeping your HVAC system clean and well-maintained, you can further reduce indoor air pollution and improve your overall air quality.

Also keeping heating and cooling coils is critical, here is a simple and cost effective way to keep your coils clean and pure.

Ventilation and Fresh Air

Proper ventilation is essential for maintaining good indoor air quality. Here are some tips for improving ventilation in your home:

  • Open windows to let in fresh air
  • Use exhaust fans in bathrooms and kitchens to remove pollutants
  • Ventilate your home at least once a day for a minimum of five minutes
  • For even more effective ventilation, ventilate for longer periods of 15 to 20 minutes

By following these tips, you can ensure that your home has proper ventilation and improve indoor air quality.

Ensuring proper ventilation and fresh air circulation in your home can help dilute and remove indoor air pollutants, promoting better respiratory health and enhancing indoor air quality. By combining these additional solutions with air quality monitoring, you can create a cleaner and healthier living environment for you and your family.


In conclusion, monitoring and improving indoor air quality is essential for maintaining a healthy living environment. By selecting the right air quality monitor, ensuring proper placement and maintenance, and integrating it with your smart home system, you can effectively manage your indoor air quality. Additionally, by considering air purifiers, HVAC filters, and proper ventilation, you can further improve your indoor air quality and create a cleaner, healthier home.
