It is a known fact that we spend a large portion of our time indoors. This means we are more likely to breathe in indoor air than we do, outdoor air. The air indoors is recycled over and over allowing it to trap debris and dust in the air, which makes it more polluted than outdoor air. The quality of indoor air might not matter to some, but for people who suffer from respiratory-related illnesses, the condition of the air they breathe in is very important. Dust, pollutants, and harmful gases such as carbon monoxide from the exhaust, can be detected with the use of an indoor air quality monitor. An indoor air quality (IAQ) monitor is a sensor-based device that is used to measure the concentration of air pollutants, temperature, humidity levels in your environment. With an indoor air quality monitor, you can become aware of whichever pollutant is causing your allergies and fix the problem. It comes in various sizes, portable and can be used anywhere in the home. An indoor air quality monitor detects poisonous gases in the home and alerts you in real-time, protecting you from any health hazards like asthma attacks or breathing issues. 

In this article, we’ll help you select the best air quality monitor that suits your home. Here is a review of the top 8 portable air quality monitors for the year 2020.

The Best Features of An Air Quality Monitor to Look for Buying Guide  

If you are looking to buy the best indoor air quality monitor, there are a few factors you would need to consider before making your pick. 

  • Accuracy and Reliability:

The first thing to look out for when purchasing an indoor air quality monitor is the accuracy of its measurements. A good indoor air quality monitor should be able to provide a correct reading of the amount of pollutants present in your air. This is important because the readings are what enable you to identify the pollutants and their cause. It should also provide reliable readings that are repeatable and do not fluctuate. 

  • Response time: 

Devices that respond faster are often indicative of high quality. When purchasing an indoor air quality monitor, consider how much time it takes to measure and present accurate results.

  • Calibration and sensitivity:

The best indoor air quality monitors are already calibrated and do not require any further calibration. They are also very sensitive and can detect low levels of pollutants in the air.
