I love when companies manage to release a second generation of their original product. In this case, Awair released the new Awair 2nd Edition a few months ago.
They clearly have learned a lot and the adjustments they have done and offer with the new version are notable at least hardware-wise. Software-wise the tweaks are small in comparison with the old version but welcome. This can be a good thing because old users can enjoy similar features like the new ones.
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.
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 »
Who says that everything is made in China or USA? Well, let me introduce you the uRAD Monitor A3 an Air Quality Monitor which is made in Romania, Europe since 2012. The design, firmware design, server software and big data database maintenance and development are all made there and amazingly enough even the unit that I have on my hands is made personally by the CEO Radu Motisan. As a result I am very proud to review it and talk about the cons and pros.
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.
Finally is here. After having an adventure with the postal service for +40 days the uHoo device found its way to my home. I want to thank uHoo for its persistence.
Let me start by saying that this is a very promising device because it features 9 separate Sensors for Air Quality monitoring and there isn’t any other device with so many sensors for indoor use. The company was founded in August 2014 and it took them two and a half years to develop uHoo.
Have you ever noticed that the water tastes different when you leave it in a glass on your nightstand overnight?
In general during the 8h sleep, CO2 is built inside the room. Especially in winter when we don’t ventilate as frequent and CO2 can reach levels higher than 2,000ppm inside the house. CO2 is a soluble gas and water is the perfect solvent. As a result a process called Acidification is occurred naturally and the PH lowers during that process. That gives your bedside glass of water a horrible taste.
In this experiment I will demonstrate how fast Carbon Dioxide CO2 rises inside a room by lighting two small candles.
I chose my study room as it can be easily isolated, plus I have got all the AQI monitors inside this room for the purpose of the experiment. The room is 7.3m². The experiment is easy, I lit 2 candles and closed the door and window of the room. Then I waiting with myself inside the room till the CO2 reached 1200ppm. Basically I logged the time when the CO2 was 430ppm and when it reached the 1200ppm with and without the candles.
With the candles the CO2 needed 35 minutes to reach the 1200ppm limit as you can see on the graph below and without any candle and with exactly the same conditions as before the CO2 needed 59 minutes to reach the upper limit.
You gain 25 minutes of more oxygen and less CO2 until the room reaches the 1200ppm limit which means more productive time and fewer headaches.
They look nice and they smell even better, but unfortunately most of them are made of toxic ingredients and when you light them, they diffuse all these toxic ingredients inside your house.
Most commercial candles are full of toxic ingredients that many times they don’t even write on the package like Paraffin, Acetone, Trichlorofluoromethane, Carbon Disulfide, 2-Butanone, Trichloroethane, Trichloroethene, Carbon Tetrachloride, Tetrachloroethene, Chlorobenzene, Ethylbenzene, Styrene, Xylene, Phenol, Cresol and Cyclopentene. Most of them are VOCs and the majority of the AQI monitors with VOC sensor will recognize the toxins in the air. Now, when paraffin burned releases toluene and benzene which are highly toxic and carcinogens (these fumes are the same as when diesel is burnt).Read More »
