The Next Air Quality Monitor

Sotirios Papathanasiou14 Comments

There are hundreds of Air Quality monitors out there but still there isn’t a single one designed and built to meet people’s needs and capture the market’s attention, each time they miss something. Companies are missing key functions for a good Air Quality monitor, hardware-wise and software-wise.

After years of experience and countless conversations with users and professionals via email/twitter/skype I know what is missing from the market.

If you are an entrepreneur or a business developer or a company that is planning to develop one more air quality monitor, remember to contact me first because I am going to bring substantial information to your company for the Next Air Quality Monitor.

PM2.5 & PM10 Sizes

Sotirios Papathanasiou2 Comments

On the short 3D animation below we can see what are the actual sizes for the PM2.5 and PM10 particles in comparison with a pin, a human hair and a sea salt grain. Pay attention on how tiny is the PM2.5 particle. Now, imagine these particles penetrating deep inside your lungs and the damage they can cause.

Summer is here and once more fires are burning woods and forests in the northern hemisphere from Greece to USA and unfortunately most of the times because someone irresponsible and crazy enough “thought” that he/she will benefit from it.

In this article I am going to discuss the chemical reactions that occur while wood is burnt and the gasses that release into the atmosphere.

Electric cars VS The World…

Sotirios Papathanasiou4 Comments

I recently came across an article in Science focus where they discuss “How environmentally friendly are electric cars?”

They also have a chart on the article with the CO2 emission each technology Petrol, Hybrid, Electric and Hydrogen produces. I fundamentally believe that this chart can create wrong impressions to the average driver who lacks knowledge on how energy is produced and what emissions are.

Time-to-time See The Air readers contact me because they want to know if some portable Air Quality monitors made in China worth an investment, so I decided to research and find out which of them is the best. First, I cross checked the features as they were presented online and I noticed that some of them have a laser Particulate Matter PM2.5 sensor, which is good, and some other use an optical one. With that in mind, I purchased the WP6930S.

Musk’s Flamethrower

Sotirios Papathanasiou1 Comment

Elon Musk needs money for his projects, so he decided to sell a flamethrower and apparently everyone is so exited about this useless device. A huge hype for a device that doesn’t complete any purpose.

Of course, my real worries aren’t whether the flamethrower has a purpose or not but what consequences will have to the environment. A device which throws flames everywhere and is capable to destroy forests, houses and burn habitats. More importantly, we suppose to fight against global warming and yet we create more devices which burn oxygen and generate carbon dioxide CO2 and air pollution.

BRISE C200 PM2.5 Efficiency Tests

Sotirios Papathanasiou7 Comments

On the previous article, I presented a new air purifier with an A.I. Engine called BRISE C200. In general, the best way to prove the efficiency of an air purifier is by taking measurements with a respectable 3rd party AQ monitor while there is an air quality issue ongoing inside the room and that is what I did. I used the uRAd A3 Monitor for the measurements and the device was placed near the purifier.

At first, I had set the purifier off on purpose because I didn’t want the A.I. engine to kick in automatically before I was able to register the event. When a PM2.5 spike was registered, as you can see on the picture below from 4μg/m3 to 26μg/m3, I turned on the purifier and the air quality inside the room immediately improved till it returned to the normal PM2.5 concentration and the purifier turned itself off automatically.

AQ-BRISEC200

In the picture below you can see the FC200 4-in-1 Combo filter after one month of usage. The carbon pre-filter has captured PM10 particles, hair, dust and even a little dead spider, which was caught by the purifier’s air flow when it was set on Turbo Mode. After that, we can see the blue anti-bacteria filter and under it the HEPA filter responsable for capturing all PM2.5 particles. Finally, the TiO2 will absorb harmful chemical vapors.

FILTERS C200 BRISE

I wanted to repeat the experiment with the BRISE C200 purifier and a different AQ Monitor in a different room and day, so with the help of the AirVisual AQM I set them up in my bedroom. This time it took 14 min into Turbo Mode to clean the air, the bedroom is a bit bigger. When the purifier achieved a concentration of ±1μg/m3, I turned it off and with the door closed the air inside the room was kept clean, but immediately after I opened the door the air quality was decreased. Below you can see the results.
