However, you can also get air quality monitors that can detect noise levels (dB) and Volatile Organic Compounds (VOCs). It is worth noting that these units are usually more expensive to buy. Therefore, if you are only concerned with healthy levels of carbon monoxide and carbon dioxide in your home, you can just invest in a simple air quality monitor. But if any member of your family has an allergy or other respiratorys conditions, you might want to consider investing in a model that has the capability to detect small particles and VOCs.

Size of Particulate Matter (PM)

Besides monitoring carbon dioxide and VOCs, a good air quality monitor should also be able to measure PM levels. You should realize that PM levels play a crucial role in determining the overall indoor air quality in an environment.

So, it is imperative that you buy an air quality monitor that has the capability to measures size of particulate matter. Otherwise, you might not get accurate readings from your device.

Temperature and Humidity Sensing Capability

The best air quality monitor should be equipped with temperature and humidity sensors. You should realize that high humidity levels can cause mold as well as increased levels of mold spores in the air.

These impurities are associated with nose and throat irritation, sore eyes, as well as coughing and wheezing in asthmatic individuals. So, it is advisable to invest in a monitor that can detect these impurities in the air in your home.

How are the Readings from the Air Quality Monitors Relayed?

It is imperative that you properly understand and interpret the results from the sensors in your air quality monitor. You know what this means? You need an air quality monitor with a good interface and app, which can translate the air quality readings and present them in a way that is easy for you to read and understand.

In fact, a good air quality monitor should send warnings, in the form of alerts to an app, text or email. In that way, you will always be up to date on how polluted the air is in your environment. Besides being able to display the reading on the device itself, the air quality monitor should also have data logging capabilities. And what’s the significance of that?

You will be able to track long-term trends. Moreover, the best air quality monitor should be able to determine air cleanliness based on a relative measure. Namely, the device should understand when the air is really clean, instead of just indicating the changes in the air quality.

Generally, a good air quality monitor should have an easy to read LCD screen. You want to look at the screen and be able to actually determine the quality of the air without having to refer to an app or computer.
