What is a normal AQI?

The Air Quality Index ( AQI) can be categorized from Good to dangerous. AQI would state as Good when the range is between 0 to 50. When the AQI is between 51 to 100, it will state Moderate to alert us that the air quality might cause health concerns for certain group of people.

50-100 Moderate
100-150Unhealthy for sensitive groups
150- 200Unhealthy
200- 300 Harmful 
300- 500Dangerous 

What is a healthy humidity level?

In general, the relative humidity value is 50%, but the optimal value is different in every room. The value in living, sleeping and working rooms should be between 40-60%, in the kitchen between 50-60% and in the bathroom between 50-70%.

What is PM 2.5 and how different it is from PM 10?

Particulate matter (PM) refers to tiny particles or droplets in the air with a diameter of 2.5 micrometers or less. PM 2.5 are so tiny that they can enter the Bronchia and the Alveoli, while the PM 10 can only reach the nasal cavity, its just the matter of the size between PM 10 and PM 2.5. Both can be associated with health concern issues, since the particles are so small that can transmit deeper into our respiratory system.

When is a safe level of CO²?

When the CO2 level is at under 1,000 ppm it will be categorized as Good. As long as CO2 level is under 2,000 ppm it will still be categorized as normal. However, when the CO2 level is over 2,000 ppm then it might be cause headaches, sleepiness, and feeling of stuffy air.

What is CO² ppm?

The carbon dioxide (CO²) concentration is measured in ppm. Ppm is the abbreviation for “parts per million” i.e. 1 ppm = 1 times 10-6. Carbon dioxide levels can rise very quickly in poorly ventilated rooms.

What is VOC (Volatile Organic Compounds)?

VOCs are volatile organic compounds that are usually used for indoor air quality assessment, for which there are recommendations from the Federal Environment Agency (Umweltbundesamtes) with regard to the maximum values. VOC are gaseous and vaporous substances of organic origin in the air at room temperature or higher temperatures. VOCs include aldehydes, alcohol, hydrocarbons, benzene, but also many other organic compounds that are formed in biological processes.

What is TVOC?

TVOC – Total Volatile Organic Compounds

TVOC can be explained as all the VOCs added up together. To be simple, TVOC are a group of thousands of organic chemicals that evaporate at low temperatures.

What is an Air Quality Monitor?

The Air Quality Monitor is a multifunctional product which can detect:

  • Carbon dioxide (CO)
  • Total Volatile Organic Compounds (TVOC)
  • Particulate Matter 2.5, 1.0, 10 
  • Air quality index
  • Temperature
  • Humidity

The air quality detection device, combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO), Total Volatile Organic Compounds (TVOC), PM 2.5, PM 10, PM 1.0, temperature and humidity on its digital LED display.
