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.
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.
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

It has been over a year since the last time I used the Awair an Air Quality Monitor. As a result, I believe it is time for someone else to use it instead of waiting inside its box. I am offering it for free to a lucky reader of my blog.
It is not a new product but it has been well maintained by me. It is a great AQ Monitor with a lovely design for monitoring CO2, Temperature and Humidity. You can read my comparison tests 1, 2 and 3. It features a PM sensor which unfortunately isn’t very good (Don’t rely on the PM sensor too much) and a VOC sensor in case you would like to get a broader picture of gases inside your house. The device comes with a EU Type C plug.
To be able to win the AQ Monitor you have to follow me on Twitter and retweet the original tweet that includes the hashtag #SeeTheAirAQM.
Additionally, for those who will leave a comment below they will have double chances of winning, remember to mention your twitter name.
The winner of the prize draw will be selected at random on 15th April 2018 at 12pm.
Shipping costs and possible customs fees are not included. The winner has to pay for the parcel and he/she is free to choose a postal service of his/her choice. The box with the device and cable weighs 920grams/2.03pounds.
Many times I have mentioned that a simple VOC sensor isn’t enough to determinate if the air quality is good or not especially in interior environments. Formaldehyde CH2O is a VOC and since I have an AQ monitor uRAD A3 that features both a Formaldehyde sensor and a VOC sensor I will try to find out if there is a correlation between them.
I have been monitoring my house for Formaldehyde for over a month now by leaving the AQM on including while I was out on a trip for 4 days and during that time the house was well closed. This kind of experiment allowed me to determinate if my furniture, paint, etc outgassing Formaldehyde.Read More »
