Best Air Quality Monitors for Mold

We have reviewed the best air quality monitors for mold. If you are in a hurry, then the table below gives a quick snapshot of the top 5.

Table could not be displayed.

Indoor Air Quality (IAQ) refers to the air quality within buildings and residential complexes. It is an important measure of the health and comfort level of the inhabitants. You might be surprised to know that indoor air quality can even reach levels over fifty to a hundred times worse than the outdoor air quality. 

The ill-effects of exposure to indoor air pollutants can sometimes be experienced immediately, but at other times, you might end up not realizing them before years have passed by. The most common symptoms include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. 

How quickly you react to indoor air pollutants depends on several factors such as age and pre-existing medical conditions. It is also possible that multiple exposures over a short period of time can cause a severe reaction.

Most people never realize that they might be continuously breathing polluted indoor air, suffering from ill-effects of repeated exposure to health hazards. So how does one get to know about IAQ?

The determination of IAQ is done by collecting air samples, monitoring human exposure to pollutants, and computer modeling of airflow inside buildings. Real-time indoor air quality monitors are used for this purpose. 

These real-time monitors identify several factors like temperature, humidity, luminosity, carbon dioxide presence, carbon monoxide presence, etc. in real-time. This is then put together as easy to understand readings for consumers to analyze their indoor environment in detail. 

By having an IAQ machine, residents can be forewarned and can take action in real-time to secure a safe and healthy place to live. The most common indoor health hazards can be categorized into three categories:

  • Chemical (Radon, Carbon monoxide, Nitrogen dioxide, etc.)
  • Physical  (Second-hand tobacco smoke, particulate matter from fireplaces with size greater than 2.5 micrometers, etc.
  • Biological  (pollen, molds, bacteria, viruses, etc.)

What makes the Best Air Quality Monitor for mold?

While considering which air quality monitor will be the best for detecting pollutants, choose a device that is accurate and easy to understand. Once you’re alerted of the presence of dangerous particulate matter, you can take action to tackle it initially by opening windows to allow ventilation.

Some air quality monitors can trigger other smart built-in appliances such as an air purifier, a fan, or a dehumidifier. Lastly, a good IAQ monitor should provide enough red flags for you to examine and eliminate the source of trouble in your air quality.

Here are some of the features that are must-have for determining the best air quality monitor for your living space!

Monitor Reading Coherency

Using an air quality monitor should help you better understand your environment. Look for a product with a simple, intuitive screen and controls that allow you to check the air quality instantly. These appliances are designed to help to make complicated issues simplistic. When shopping for the finest air quality monitors, look for devices that are easy to interpret.

Least Particle Size Detectable by Monitor

The fine particles having size 2.5 micrometers and less are considered to be hazardous to health. They lead to breathing problems, respiratory illnesses, lung diseases, Bronchitis, and even Cancer. Low-quality particulate matter sensors can only read particle sizes down to 1.0 micrometers. The best air quality monitors will not be able to detect much below the 0.5 um mark.

Smart and Innovative Framework

Most people do not want to keep checking their air monitors and note down the readings. Most air quality monitors have connectivity to your phones and laptops, and can record your data for your further analysis and study


Monitors should be able to report the accurate concentration of the gas or pollutant that is to be measured. The device should also not report inaccurate readings or false-positive and false-negative results. The device should respond quickly as quick response time is usually a characteristic of a higher-quality device.

The device needs to be sensitive enough to pick up low levels of pollutants. The results should be repeatable and not waver at separate time intervals. Finally, the device should already be calibrated, with no further calibration necessary.


Another feature of an ideal air quality monitor is its durability. 

For instance, while measuring gases, and ozone in particular, if the sensor is not good enough, the readings will not be accurate, especially when considering the long-term usage. Also, exposure to extreme heat, dust, temperature fluctuations, and being dropped or dented can all have an impact on how long a sensor lasts

#7 Airthings Wave 1st Generation

Airthings Wave 1st Generation


Find out more on Amazon

The Airthings wave 1st Gen is largely a radon gas detector, though it also monitors humidity and temperature, and therefore it comes highly recommended as an air monitor specifically for molds.

This is a really interesting smart device that has possibly the simplest interface ever – just wave in front of the machine and it will show you a color-coded air quality meter – green/yellow/red.

But that’s not all it can do. You can connect it via Bluetooth to your phone/laptop and use the compatible app to get a complete dashboard with detailed insights into your air quality.

In addition to this, it can be connected to most smart home devices – Alexa, Google assistant, and “If this then that”.

The device is battery powered, so it doesn’t need an AC outlet (one less EMF radiation to worry about). 



  • The Bluetooth connection is not consistent and therefore you cannot have constant monitoring of the air if that is what you are looking for
  • There are sync issues with other smart home devices, especially IFTTT.
  • Does not have wi-fi connectivity, only Bluetooth. Sometimes it is difficult to connect devices with only Bluetooth, especially if there is a wall or object in between

Airthings Wave 1st Generation...
  • CONTINUOUS MONITORING: Radon gas fluctuates daily. Access your radon levels in real-time to take control, make changes and minimize potential health effects.
  • RELIABLE RADON RESULTS: An accurate and reliable radon detector for every home, office and building with extra humidity and temperature sensors as standard.
  • QUICK AND CLEAR RESULTS: Connect via Bluetooth to the Air things App or log in to the Air things Dashboard online for detailed insights into your air.
  • EASY TO UNDERSTAND: Simply wave in front of the device to receive a color-coded visual indicator of the overall air quality; Green (Low), Yellow (Warning), Red (Danger).
  • NO LAB FEES: Get both long and short term radon results straight to your smartphone and easily generate a radon report through the Air things Dashboard.

The real-time monitoring by an Air Quality Monitor is a significant method to detect the presence of indoor air pollutants. These pollutants are present in our homes without our knowledge, leading to health-issues either instantly or over long periods, depending upon factors such as age and duration of exposure. 

These monitors also provide support for the clinical analysis by medical specialists to analyze the history of IAQ conditions of the environment and link these data with their health issues. By controlling IAQ, it is conceivable to identify the hazardous air quality conditions appropriately and plan interventions for enhanced living environments.
