17 Air Quality Apps

Sotirios Papathanasiou3 Comments

Not everybody can afford an AQ Monitor or simply not everybody wants to spend money on a AQ Monitor. That’s fine because here are 17 Free/Paid apps for you to check the outdoor air quality in your area. Some of them can notify you when the Air Quality is poor and guide you on breathing cleaner air. Unfortunately some apps don’t support some regions, this is because some developers face difficulties to obtain data from local authorities. (The public air quality stations in my region suck!)

CALIOPE (Free) ♥♥♥

caliope

Caliope is an air quality forecast system for Spain, developed at Earth Sciences Department of the Barcelona Supercomputing Center – National Supercomputing Center (BSC-CNS). The app supports all Spanish regions and the website version supports most European countries. Available data O3, NO2, SO2, PM10 and PM2.5. Maps and Pollutants. The website is available in English and Spanish.

EPA AIRNow (Free) ♥

EPA

The EPA AIRNow was designed by the United States Environmental Protection Agency. Although the agency has access to all the US AQ stations and a huge amount of data, the app is plain and with a very poor design. There is nothing special about this app. Even the icons are pixelated. They should be ashamed, the app looks like an internet page from 1999.

AirVisual (Free) ♥♥♥♥♥

airvisual

AirVisual provides a free app for their device Node/Pro but it also works without it.  You can have access on a huge amount of outdoor AQ Stations around the globe. With a history browsing for all the pollutants, maps, ranking and news. The data are from public stations but also from their devices around the globe.

Wunderground (ads) ♥♥♥♥

Wunderground

Wunderground is basically an advance weather forecast app but they also provide air pollution data if you are lucky enough, which means depending the weather station they use to get the data for your area. If the weather station in your area has air quality sensors then they will provide you with the data.

Plume (Free) ♥♥♥♥

Plume Labs has design this app to help people avoid air pollution. Their app offers an air pollution forecast. It is a simple but a complete app. You will see an Air Index at the home screen, weather conditions and the activities that they recommend you to do depending the air quality at that time. They use public AQ stations but they will also combine the data from their devices in the near future. It supports notifications.

CleanSpace (Free) ♥♥♥

cleanspace

CleanSpace focuses on Carbon Monoxide air pollution. On the home screen you can see the “current” air pollution from your device but if you don’t have a device you can also browser their air pollution map. They also provide some weather data from the local weather station. A bit limited on the pollutants.

Air Quality (Free) ♥♥♥♥

Air Quality

The app exist on the app store with 2 different icons but the same name, by the same developer and the same interface. It is a very nice app with plenty of data. The app has some nice animations and a clean design.

Airpocalypse

This app is for the Chinese citizens because only supports Chinese cities. Super Clean design and some funny icons and quotes.

BreezoMeter (Free) ♥♥♥

Air Checker (ads) ♥

Wildfires and Air Pollution

Sotirios PapathanasiouLeave a comment

The last few months and due to the lack of rain and the climate change some places in the world are facing extreme wildfires, most of the times manmade. Places like Galicia-Spain, Portugal and California-USA have been facing a great danger. The wildlife has been left without its habitat and humans without clean air. Unfortunately this kind of distraction creates enormous quantities of air pollution. A lot of times the air pollution spreads downwind from the fire source and even reaches other countries, so-called Cross Border pollution.

What kind of pollutants do the wildfires produce?

Mainly wood smoke contains a mixture of PM2.5, PM10 particles and various gases. More precisely wildfire smoke is a mixture of carbon dioxide, carbon monoxide, volatile organic compounds VOCs and a wide rage of particulate matter PMs that include ash, black carbon BC and organic carbon, such as Polycyclic Aromatic Hydrocarbons PAHs.

The smoke is a very complicated mixture of pollutants in the air, and it affects human health. It comes from lots of different sources, including trees, decomposed leaves, animals, forest litter and sometimes from local houses. Even the composition of the air pollution is depending on the way the smoke is created, for example by smouldering or flaming.

How to protect yourselves?

If you live close to a forest then ask your local authorities how you can help to protect the Earth’s lungs. If you happen to be near a wildfire/forest fire then remember to wear a N95 or N99 face mask. Don’t expose yourself in the smoke for a long time, even the face masks have a limit. If you live near an ongoing wildfire, close the windows and seal your house from the outdoor air. Stay away from your house for a few days, ask a family member who lives far away from the fire to host you.

Request

I can’t stand reading or watching on TV news regarding wildfires. The damage is huge especially when humans are responsable for them. My heart breaks every time. Please respect the environment. Thank you.

DIY PM Monitor Take 2

Sotirios Papathanasiou4 Comments

Do you remember this DIY Low cost DIY PM Monitor, there is a new and better version available.

The new version offers a low cost housing and the software is more mature now. The software is open source, on github, and there are some pre-built images on their website.

A great new feature is the ability to store of a few days of data on the device which makes it more robust to internet outages and usable for periods away from wifi access, and it records every sample from the PMS5003 sensor which is more that one per second to better capture quick changes and better for mapping walking around.

You can find all the instructions on their website.

Why I am in favour of Air Quality Sensors

Sotirios Papathanasiou6 Comments

Why am I in favour of air quality sensors and I support all AQI monitors and sensors independently their price tag?

Because they help us literally See the Air. They are the only tools we can use to get hard evidence that air pollution exists and raise awareness. Someone could say that inaccurate and probably cheap sensors are useless and I will agree in some level but you have to keep in mind that not everyone can afford a +1000$ sensor. Those “cheap” sensors will allow people to discover what they breathe in some level, act on it and will make them more conscious about the pollution. I truly believe that sensors will shape future societies.

Sometimes when I talk to people about air pollution some of them don’t seem to understand that air pollution exists. They have never thought that the black smoke exiting a car is a harmful pollution. They have never thought that lighting the fireplace for a “cosy” moment has effects and consequences. They have never thought that air pollution is everywhere and can affect everyone.

When evidences are presented, people start to think and wonder. A fundamental action which distinguish humans from animals. At that moment people make a huge difference as human beings and the Oxygen that is consumed by them is not a waste. Education is the key to a better future.

uHoo vs AirVisual vs Awair

Sotirios Papathanasiou18 Comments

On this article I am going to compare three AQI monitors: AirVisual, uHoo and Awair.

All the monitors were placed together in the guest room in my house, as you can see on the picture above. I chose that room because I wanted to be able to isolate the devices from the rest of the house and from human interaction especially for the first 21 measurements. No one was allowed in that room during those measurements. After those 21 random measurements which were taken during 4 days period of time I opened the door and I created some “air pollution”. The whole experiment lasted 10 days. Below you can see the graphs with all the sensors and monitors.
