What is the Best Air Quality Monitor?

Your home is a place that should always feel safe. However, if you are concerned about air quality, you may not feel safe. The air you breathe can contain toxins, chemicals, dust and other particles. With the help of an air quality monitor, you can learn what pollutants are present in the indoor air and solve the problem. Some air quality monitors are hand-held, so you can take them with you and test the air quality in your office or car.

Our purchasing guide will help you find the best air quality monitors to protect your family and pets. Temtop's portable air quality monitor is ideal for environmental testing at home, in offices, in cars, indoors and outdoors. It is the ideal tool to monitor air quality for up to six hours on a full charge and has a color LCD screen that is easy to read.

Here are some considerations when selecting an air quality monitor:

Pollution Detected

Air quality monitors can detect all the different pollutants in the atmosphere, but not all models can detect the same materials. Before buying, check your monitor for detectable contaminants to make sure you can see your top concerns.

Common Pollutants

CO2 (carbon dioxide) and CO (carbon monoxide) :

Although carbon dioxide is naturally present in the air, it can be dangerous when it accumulates because of problems in a home heating system. If CO concentrations are found to be high enough, it can be a deadly gas. Because it is colorless and odorless, it is not easy to detect. Air quality monitors measure CO2 and/or CO in PPM.

Fine dust (PM), such as dust, pollen, mold and smoke:

Particulate matter often hovers in the air, causing allergic reactions and other breathing problems. PM refers to particles between 2.5 and 10 microns in diameter, called PM10. Objects smaller than 2.5 microns are called PM2.5. Not all air filters remove PM2.5 particles. Even if you use a filter system, you may have something at home.

Volatile organic compounds (VOC) :

VOC is released in the form of gases from certain solids and liquids and has both short - and long-term health effects. Vocs are released by paints, gasoline, pesticides, aerosols and other chemicals. Air quality monitors can detect one part per billion (PPB) of VOC.


A radioactive gas that occurs naturally in the environment but can cause cancer. Because it is colorless and odorless, it is dangerous to accumulate in a house. Since not all air quality monitors can record ra values, separate tests may be required.


If you use an air quality monitor in more than one place, you'll find a small model that's easy to carry around. They usually fit in your hands, and some even attach the monitor to a garment or bag with a clip. Other monitors are large physical models that should be kept in one place.


Some air-quality monitors, including those with rechargeable batteries, run on batteries. You must connect to other monitors and limit where and how you can use them. The advantage of the electric model is that you don't have to worry about monitoring your house's air quality.


Display Screen:

Not all air-quality monitors have screens. Some models only light up when certain contaminants are found. Using the screen makes it easier to use the monitor because you can easily see the monitor's test results.


If you do not need equipment that monitors only the air quality of your house, choose an air quality monitor with filtering capabilities. In this way, you can purify certain pollutants from the air, which can not only diagnose the problem, but also solve it.

Wireless Connect:

Some air quality monitors can connect to your home WiFi network and send readings to smart home devices. That way, you can keep your data in a smartphone app to track your house's air quality over a longer period of time.


Pay between £30 and £400 for an air quality monitor. Basic models without screens typically cost between £30 and £100, while basic models with screens and filters cost between £100 and £200. A large fixed seat model to clean the air costs between £200 and £500.

Handheld monitors are often easy to carry and can be used to monitor air quality in homes, offices and even cars. You can also find the source more easily by moving it to the location of the suspect problem. In general, fixed models are best suited for consistent emergency monitoring.

Replace or clean filters in HVAC household systems to ensure that air is cleaned as efficiently as possible. You may need to test the heating system for problems that might release potential toxins. Regular vacuuming and dusting can also help limit particulate matter in the air.
