A reader of the blog took the initiative to establish a contact between PurpleAir and me, as a result the PurpleAir II outdoor Particulate Matter monitor is here for a review. Thank you Daniel.
The monitor is very compact and it can be easily distinguished from the rest because it has 2 Particulate Matter sensors. Both of them work together to establish better results and a coefficient of determination (R²).Read More »
We all enjoy a clean and cosy house free from dust and pollutants. Unfortunately, sometimes we commit serious mistakes when it comes to the decisions we take and the ways we choose to clean it. One of the most common mistakes is using vacuum cleaners that don’t have a HEPA filter. We already know how dangerous are PM2.5 particles because they can penetrate deeply inside our bodies and affect our lungs, heart and even our brains.
The battle begins, I am going to dive right into the comparison. In this comparison I am only going to compare the PM2.5 sensors because a good PM2.5 sensors says a lot about the quality of the device. The participants are:
Here are all the available and not IAQ Monitors on the market. This time I included a new row with the Year each device became or will become available.
A PDF version of the table is available here: Comparison AIQ 2018 Q4
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.
