Thailand School sets the AQ bar high – An example to be followed

Sotirios Papathanasiou4 Comments

On Earth, there are over 7 billion people but very few of them have a clear vision of a future and how important air quality is for our health. You will find politicians that are unwilling to enforce air quality laws, you will find educators scared to share with parents the indoor air quality, and you will find lots of people unaware of what they breathe or what they burn.

Among all of them, you will find very few people that want to make things right for the rest. In this case, the Head of School at Prem Tinsulanonda International School in Chiang Mai, Thailand was brave and educated enough to recognize the power of air quality data.

Chiang Mai is a city in exotic Thailand that always ranks in the top polluted cities in the world between March and April. The reason is the burning season. I was taught about the 4 seasons (Spring/Summer/Autumn/Winter) at school but it turns out that they have a fifth season − normally in March and April − when crop waste burning and forest fires fill the air with particles, PM2.5 levels can reach 300 μg/m³.

Review: XT Mini by Ethera Labs

Sotirios Papathanasiou1 Comment

Managing air quality monitors (AQM) in buildings is not always an easy task especially if you have deployed a lot of them. When there are many rooms that you have to take into consideration it can become very costly, very fast to equip all those rooms. Is there a way to monitor rooms without an AQM?

Well, it turns out there is a way to monitor the environmental and air quality conditions in rooms that do not have physical monitors nowadays. How?

Ethera Labs, which is a French company, with over 10 years of experience in professional IAQ solutions has integrated powerful Machine Learning (ML) algorithms that predict the conditions in rooms where air quality monitors are not installed, yes that’s right, you have read correctly. They have trained special neural networks by taking a lot of parameters into consideration in order to predict accurately the conditions and alerts users in case they need to take actions or even address an AQ/Environmental incident automatically.

By connecting the station to BMS, they manage to achieve energy efficiency while directly managing the ventilation system, as well as portable air purifiers or giving building operator the right information in advance so they can take action at the right time. They achieve two goals, great air quality and energy efficiency.

Hardware-wise Ethera Labs offers an arrange of monitors that can address different building specifications and needs. In this article, I will review the Mini XT Basic (MX-KIT020) and the NEMo Cloud/Supervision Cloud platforms.

Review: Aether Air HA30 an in-Vehicle Air Purifier

Sotirios Papathanasiou5 Comments

Commuting to work is proved to contribute the biggest daily exposure to air pollutants according to the University of California. Car filters are not very good at filtering out PM1, PM2.5, and PM10 particles from vehicle emissions as they were originally designed to catch large particles like dust and pollen. Gas filtration is non-existence even today in any vehicle, as a result, drivers and vehicle passengers breathe notorious toxic fumes.

Although I believe that if you live in a city and you work in the same city, you should find a better way to commute, for some people this is not an option. Consequently, they need to find a way to protect themselves and mitigate their exposure to air pollution.

Aether Air HA30 is an in-vehicle air purifier capable of filtering particulate matter and eliminating nitrogen dioxide (NO2) among other chemicals.

It uses the same technology as the HA500 domestic purifier but in a smaller package. The D-Orbital Nano Oxide (DNO) filter, which is an innovative filtration system invented by the founding CTO of Oxford Catalyst plc (a leader in novel industrial catalysts)” and a HEPA 13 filter.

uRADMonitor SMOGGIE-PM | Call for Volunteers Take 2 [Ended]

Sotirios Papathanasiou14 Comments

Back in 2019 uRADMonitor and I organized a “Call for Volunteers” where we gave away 10 monitors all around the world.

Once more we are looking for five volunteers who want to receive a Smoggie-PM monitor. The new version comes with new transparent icy look case and visual indication of the pollution concentration thanks to the LED light.

Volunteers all around the world who are willing to install an Air Quality Monitor in their backyard or balcony or window or any other outdoor environment in order to build a better air quality network and to help you raise awareness in your neighborhood/community.

The only requirement from your side is to have a good Wi-Fi internet connection 24/7 and keep the device on constantly in order to broadcast the measurements to an open map. The WiFi signal must reach the monitor outdoors.

Just email or tweet or DM me on any social media platform, tell me where are you planning to install the monitor and why should I choose you.

What is SMOGGIE-PM?

Smoggie-PM is an ultra low-cost high performance Air Quality Monitor, with Wi-Fi connectivity and a laser scattering sensor (Plantower PMS5003) that measures Particulate Matter PM1, PM2.5 and PM10 and makes it available on your phone or laptop in real time. Also, it is equipped with a Temperature/Humidity/Pressure sensor (Bosch BME280).

Smoggie is an automated, fixed, Air Quality monitoring station. It has WiFi connectivity to send the air quality measurements to the uRADMonitor Cloud in real time. It needs 5V to run, powered by a standard micro-USB cable (the same your smartphone uses in order to charge it). The new versions have a color LED light that reflect the pollution levels in real-time.

Review: HA500 Air Purifier by Healthy Air Technology

Sotirios Papathanasiou13 Comments

It is not always an easy task to keep indoor air free from pollutants, especially, when Nitrogen Dioxide (NO2) is present in indoor environments. In most cases, there is little you can do to eliminate NO2 and other gases like Sulphur Dioxide (SO2), Formaldehyde (TVOC), or even pathogens like H1N1 Influenza A virus (pandemic flu), and Staphylococcus aureus (or similar bacteria).

Here comes the HA500 Air Purifier by Healthy Air Technology which is able to eliminate all of these pollutants/pathogens from indoor environments. It does that thanks to the triple-layered system with a primary filter, HEPA 13 filter, and Pollution Eraser DNO filter. DNO means D-Orbital Nano Oxide which is made of two parts. 

1st part: The Carrier – Activated charcoal. The material that is used in military gas masks, and captures pollutants within the pores of the charcoal.
2nd part: The Transition metal oxides – Transition metal oxides are coated in the activated charcoal to form catalysts, and these catalysts break down pollutants and toxic gases into harmless chemicals and then release these harmless materials back into the atmosphere like water, oxygen, carbon dioxide, etc. The DNO is invented by the founding CTO of Oxford Catalyst plc (a leader in novel industrial catalysts).

Poll: Results Discussion – Air Pollution

Sotirios Papathanasiou5 Comments

Last week I started a brief poll on Twitter because I wanted to obtain feedback from the community. The subject was simple “Which source of #AirPollution affects you the most?”

263 people responded and unfortunately, I can’t say that the results surprise me. Vehicle traffic was voted as number #1 source of air pollution with a massive 53% and it was followed by 32% wood burning for heating like wood-burning stoves, fireplaces, etc. 7% of the users voted that agriculture is the source of air pollution in their communities and an 8% voted other.

I would like to comment about each category individually, but first of all, I would like to make something clear. All sources are equally important, I don’t rank them from most to least important but I classify them based on what people think is the source in their community, and it varies a lot.
