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.
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.
For the first time I have ordered a Cordless Vacuum Cleaner with a HEPA filter. It is called Roidmi F8 Storm. It is already commercialized by Xiaomi, but currently, it is available on Indiegogo for $289. The offer ends at the end of July 2018.
Formaldehyde CH2O is a very dangerous chemical-gas that can be easily found inside a house because it off-gases from paints, carpets, furniture, etc… In this article I am going to find out how well a cheap, handheld air quality monitor WP6930S compares to a more professional solution such as the uRAD A3.
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.
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.
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.
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.
It was time to review an air purifier because it is a vital device for those who suffer from air pollution and allergies. The purifier that I am going to review is called BRISE C200. It was first launched in Taiwan in 2017, although the company’s headquarter is in the Netherlands with team members in Germany and Taiwan. I have been following this company since their first steps into the air quality market.
The reason I wanted to review this purifier first is because it is the first air purifier with artificial intelligence aka A.I. and because it combines two devices in one, an air quality monitor and a purifier, obviously.Read More »
It is well known that exposure to high levels of air pollutants raises the risk of physical illnesses such as respiratory infections, lung cancer, heart disease, stroke, dementia and Alzheimer. However, there are new studies suggesting that air pollution is responsible for mental illnesses too.
Back in 1970 Lead Pb (from the Latin plumbum) was used to be added in the petrol fossil fuel, as a result, it was later associated for contributing to behavioral problems, learning difficulties and lowered IQ among children.
In recent years, Sulphur Dioxide SO2, has been associated with a high risk of hospital admissions for mental disorders in Shanghai.Read More »
Some new AQM on the market and some older devices changed positions from pre-order to order and some others unfortunately they didn’t make it and now they are unavailable. A PDF version of the table is available here: SeeTheAir_Comparison_AQM 2018_Q2
