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) components include finely divided solids or liquids such as dust, pollen, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapours that can be suspended in the air for extended periods of time. The most serious problems cause particles which are less than 10 micrometres (PM10, PM2.5, PM1) - they can simply enter the lungs and contribute to respiratory problems and other diseases. People with pre-existing respiratory and heart conditions, diabetes, the young, and older people are particularly vulnerable.

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.

When will my Atmotube ship?

According to our plan we will start shipping Atmotube PLUS in early December 2018 and Atmotube PRO in early March 2019. Our first supporters will receive their orders first.

Where will you ship?

We ship Atmotubes worldwide!

What will Atmotube PLUS and PRO cost at retail?

The target retail price of Atmotube PLUS is $99 plus sales tax, Atmotube PRO is 189$ plus sales tax.

Does Atmotube come with a warranty?

Yes! We offer a 12 month manufacturer’s warranty on all our products.
