According to the World Health Organization (WHO), air pollution poses one of the biggest risks to human health. Unfortunately, many people think that air pollution is only a problem if you live in a big city. However,  pollutants like carbon dioxide, pollen, and dust can affect any part of the world including rural areas. An air quality monitor will help you control the air pollutants around homes, schools, offices, hospitals, and factories.

An air quality monitor is designed to check and report the presence of harmful gases, chemicals, and fine particles in the air. Since the application may vary from one monitor to the next, it is important that you are clear on what you need from your air quality monitor. However, with so many considerations to make, you may find it hard to choose the best product. We prepared this review to help you find the right monitor easily.

Air Quality Monitor Faqs

 

1. WHAT IS AN AIR QUALITY MONITOR?

According to the US Environmental Protection Agency, the air that we breathe consists of a large number of pollutants, even it looks clear. An air quality monitor is a tool that shows the quantity of pollutants in the air.

 

2. WHAT DOES AN AIR QUALITY MONITOR DO?

While necessary for life, the air that we breathe is filled with harmful substances like carbon dioxide (CO2), formaldehyde, mold, dust, and bacteria. An air quality monitor keeps us aware of the level of these substances, which can lead to breathing problems, heart disease, lung cancer, and respiratory infections.

 

3. HOW DOES IT WORK?

The main parts in an air quality monitor include the fan, which sucks in air from the environment, and a series of sensors. Gas sensors check for the presence of harmful gases like Carbon Dioxide while particle sensors look for dust, pollen, and other fine particles.

 

4. WHERE CAN YOU BUY THEM?

Online stores like Amazon have a wide variety of air quality monitors.

 

5. HOW DO I CHOOSE ONE?

You can choose an air quality monitor based on size, type of sensors, and budget. For example, people with respiratory health problems like asthma bear the greatest burden from particle pollution. They will need to look at sensors that detect the presence of fine particles like pollen and dust.
