Frequently Asked Questions
What are the VOCs?
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. In fact, they may be emitted by a wide array of products, including paints and lacquers, paint strippers, cleaning supplies, household products such as varnishes and wax, cleaning and disinfecting, products, building materials (plywood and particleboard) and furnishings, office equipment such as copiers and printers, glues and adhesives.
VOCs can cause eye, nose, and throat irritation as well as headaches, loss of coordination, and nausea. They may also cause damage to the liver, kidney, and central nervous system. Some are suspected or known to cause cancer.

What are the PMs?
Particulate Matter (PM), also known as soot, is made of microscopic solid particles or liquid droplets that are either emitted directly into the air or formed by pollutants that combine in the atmosphere. PM is usually measured in three size ranges, which are the most harmful to health: PM10, PM2.5, and PM1
PM10 or coarse dust particles refer to particles with a diameter less than or equal to 10 microns in size. They are about 30 times smaller than the width of a human hair and are small enough to evade our defensive nose hairs and get inhaled into our lungs. Sources of this PM10 include crushing/grinding operations, and dust stirred up by vehicles. Pollen, mold, and plant and insect particles are also considered PM10. Finally, the evaporation of sea spray can also produce large particles in coastal areas.
Dangerous level: 125 μg/m³ (microgram per cubic meter) or more.
PM2.5 or fine particles are 2.5 micrometers in diameter or smaller. Fine particles are produced from all types of combustion, including motor vehicles, power plants, residential wood burning, wildfires, agricultural burning, and some industrial processes. While PM10 ends up in your lungs, PM2.5 is more dangerous as it can transfer from your lungs into your bloodstream. From your bloodstream, it can it end up anywhere in your body, thereby making it “the invisible killer”.
Dangerous level: 90 μg/m³ or more.
PM1 – particulate matter with a diameter smaller than 1 micron – is a major subset of PM2.5. These are extremely fine particles that are even more likely to reach deeper into the respiratory system than PM2.5. PM1 is the by-product of emissions from factories, vehicular pollution, construction activities, and road dust. It is not dispersed and stays suspended in the air that you breathe.
Dangerous level: 61 μg/m³ or more.
Why should I use Atmotube?
People don’t realize how what’s in the air might affect our health. But there are potential dangers in the air around you. Atmotube devices can help you to detect VOC and PM pollutants and do proactive actions such as air ventilation, air purification or finding source of pollution.
How does Atmotube PLUS/PRO VOC sensor work?
Atmotube constantly monitors air pollution in real time. We utilize a MOX-based (Metal-oxide) sensor in our product. The functionality of a MOX gas sensor is based on the conductivity-change of the gas-sensitive MOX semi-conductor layers at gas exposure, which can be externally measured and analyzed. A specific MOX gas-sensitive layer reacts to oxidizable gases with increasing of the layer resistance and to reducible gases with decreasing of the layer resistance.
How does Atmotube PRO PM sensor work?
Laser scattering principle is used for PM sensor, scattering is produced by using laser to radiate suspending particles in the air, then scattering light is collected in a certain degree, and finally the curve of scattering light change with time is obtained. In the end, equivalent particle diameter and the number of particles with different diameter per unit volume can be calculated by microprocessor based on MIE theory.
How often does it take measurements?
Atmotube PLUS and PRO take VOC measurements every 2 seconds and store it to the memory every 1 minute.
Atmotube PRO measures PM on demand (by button press or via application). It takes measurements every 1 second when on.
How long does it work on single charge?
Atmotube PLUS takes can work 1 week on a single charge.
Atmotube PRO can also work a week on a single charge if you use PM sensor 10 times a day for about 10 minutes each time.
How portable is it? How much does it weigh?
Atmotube PLUS only weighs 1.4 ounces (40 grams), so it’s perfectly portable, even pocketable. It has carabiner mount to let you to clip it anywhere, on any bag or even a key ring.
Atmotube PRO weights 3.3 ounces (95 grams) and it is also quite portable.
Do I need to download the app to use Atmotube?
Yes, Atmotube sends all measured data to your mobile phone via Bluetooth Low Energy (LE) protocol. You can download our free Atmotube app from Google Play or App Store.
Can I use Atmotube without the phone?
Yes, you can – Atmotube has internal memory to store data for several days. To detect current level of pollution you can press the button and check LED color.You can sync the data later with smartphone. If you need GPS location for the readings the phone need to be close to the Atmotube device.
Will Atmotube work with any Smartphone?
Atmotube is compatible with iOS 9+ devices and Android 4.3+ devices with Bluetooth Low Energy support.
Is the Atmotube mobile app free?
Will I receive any alerts if the air quality is poor?
Yes, you will get immediate notification if Atmotube detects air quality lower than specific level to your smartphone. This notification is customizable via settings.
What is Air Quality Score?
Atmotube detects a very wide range of harmful gases, toxins and volatile organic compounds as well as PM. For your convenience we created an accumulative parameter called Air Quality Score (AQS) that can instantly give you an understanding of the quality of air around. AQS changes from 0 (severely polluted air) to 100 (very clean) points. There’s a LED on the front of Atmotube. What does each color mean? The LED color represents the current Air Quality Score. (Red - severely polluted, Orange - very polluted, Yellow - polluted, Green - moderate, Blue - good).
Is Atmotube waterproof?
Atmotube design is meant to provide a good airflow for the sensors inside, so it can’t be waterproof at the same time. Please do not put it in water. What is the operating temperature of Atmotube? Recommended operating temperature for Atmotube sensors is from -5°C to +50°C.
How is Atmotube calibrated?
Each sensor will be pre-calibrated. Sensors have sophisticated embedded algorithms to perform automatic calibration over time.
How does the Air Quality Map work?
If you will decide to contribute to Global Map - your GPS coordinates will be linked with your AQS measurements, periodically uploaded to our secure cloud, and then will be aggregated on the air quality map. The map is available for public viewing.
Who can see my Air Quality data?
Only you can view your AQS history data. But you can share it on the map to make your contribution into the global air quality map.
