Why is it important to monitor air quality during and after wildfires?

Monitor PM1 and PM2.5 in real-time

Wildfire smoke contains fine and ultra-fine particles that are dangerous to human health.

Identify severity of air pollution

Particles can travel long distances and linger in the air for several weeks in unfavorable weather conditions.

Keep track of air quality indoors and outdoors

Smoke can penetrate via ventilation, door gaps, and windows. Track your air purifier performance with real-time particle measurements.

People at-risk

People with respiratory conditions such as asthma or COPD, pregnant women, children, and seniors are more susceptible to wildfire smoke. Monitoring air quality helps at-risk individuals protect their health by reducing exposure.

General population

During wildfires, smoke can travel long distances, affecting regions far from the fire. Poor air quality can irritate the respiratory system, causing coughing and breathing issues. Being aware helps minimize exposure and protect well-being.


Monitoring wildfire-related air quality is vital for researchers due to its link to pollution and climate change. We offer a complimentary Cloud and Bluetooth API. We have already partnered with more than 100 scientific projects.

I live in Northern California where air quality has been a big issue due to wildfires. I've used Atmotube PRO to help track down areas with relatively good air where it's ok to run without my mask on and then notify me when I've moved into an area that's more polluted and I should mask up. It's made me feel less anxious.

"Atmotube PRO reading 0 on scale that goes to 100 - 0 being the worst air quality possible. That picture is looking across the Hudson River from New Jersey to Manhattan. The big apple is lost in the Canadian wildfire smoke."

"I live in Northern California where air quality has been a big issue the last few years due to wildfires. I've used this to help track down areas with relatively good air where it's ok to run without my mask on and then notify me when I've moved into an area that's more polluted, and I should slow down and mask up. Overall it's made me feel less anxious."

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.

You can find the list of VOCs here:
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.
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 portable is it? How much does it weigh?
Atmotube PRO weights 3.7 ounces (104 grams) and it is portable. Height × Width × Depth: 3.4 × 2 × 0.9 in (86 × 50 × 22 mm)
Internal storage
Atmotube PRO's internal data storage is 10 days. To retrieve the collected data, the device should be synchronized with the mobile app at least once within 10 days.
