Air quality monitors can be equipped with different types of sensors to detect different types of pollution. The accuracy and reliability of the sensor are important. The better the sensor, the more accurately it can record and report the level of pollution in the environment. There are several air quality monitors on the market today, and their performance accuracy varies greatly.

Are air quality monitors accurate?

As for VOC detection, there are currently no inexpensive VOC sensors that can be integrated into consumer products at a reasonable price and provide accurate VOC levels. Commercially available air quality monitors with VOC detection capabilities are available, but the accuracy of these sensors is questionable. To determine the accuracy of air quality monitors, we need to compare them with the more sophisticated air monitoring equipment that professionals often use to record air pollution. These devices have better sensors and better calibration. Because of their accuracy, they can be compared very well with any air quality monitor.

How do you use an air quality monitor?

Air quality monitors usually measure only a limited number of contaminated areas. Good air quality monitors are 0.3 to 2.5 microns in size. This is not always the case, as air quality monitors may not be able to detect harmful pollutants in the air because particles cannot be measured. Most home air quality monitors are best used in combination with leak-free air purifiers. Air purifiers can remove almost all particulate pollutants, including ultrafine particles, from the air, even if they are not measured using air quality monitors. When combining an air quality monitor with an air purifier, readings from the air quality monitor can be used to determine when air pollution has increased. Therefore, you can adjust the air purifier's speed Settings to match the level. You can go down.

An air quality monitor used to measure urban pollution

Particle pollutants come in a variety of sizes, of which the most commonly discussed are PM2.5 and PM10. But the most important thing is to measure 0.3 microns. Because particle pollution of this size has the worst health effects. This type of particulate pollution is also most common in cities due to exhaust fumes from burning cars. When inhaled, the ultrafine contaminant enters the bloodstream through the lungs.

The measurements below represent typical daily air pollution in London. More than 200,000 particles per cubic liter. It was a very warm day, with the temperature reaching 20 degrees.

This number may increase if you are in a long traffic jam or behind another car. All cars will provide some level of particulate filtration after activating their air conditioning and ventilation systems. However, compared to automotive air purifiers that do not provide the filtering efficiency achieved by HEPA, automotive filters equipped with standard equipment generally have very low filtration efficiency and are leak free.

Clearly, driving poses a significant health risk to people who are vulnerable to this type of pollution, as there is no easy way to reduce pollution levels. You can close Windows to limit car pollution, but increase carbon dioxide (CO2) levels. The IQAir Atem automotive Air Purifier provides A HEPA filtering function that can be used in vehicles to reduce pollution.

Laser particle scanner

As we all know, laser particle scanner or particle counter is used to measure the particle pollution of high precision professional equipment. It is far more reliable than most air-quality monitors on the market today, which use cheap sensors to detect pollution. Some laser particle scanners can measure particles of different sizes and provide instant readings compared to other devices every few seconds or longer. The laser particle scanner is very accurate and you can see where the pollution is greatest and where the sources are. Laser particle scanners are very expensive, not expensive for most people.

Particle Scan Pro allows you to measure particle pollution in a variety of sizes from 0.3 to 5.0 microns. Particle Scan Pro provides data logging. This causes the device to store particle measurements of the environment at intervals based on user-defined Settings. This allows you to analyze the data and determine patterns and trends in particle pollution. Particle Scan Pro can also record measurements on a computer in real time via A USB cable or network.
