Reviewing the CleanSpace Tag was a priority for me as it is the only available affordable $50 and easy to carry on device that measures air pollution and helps #seetheair everywhere.
Carbon Monoxide CO Sensor 0.3 to 492 ppm
Bluetooth Smart (BLE)
It weighs only 51g. When I first took it on my hands I thought it was empty inside, but it wasn’t of course. It is almost the same size as the iPhone 5/5s/5c, but thinner which makes it super convenient for handling it. Also it comes in a cool packaging, recyclable 100%.
I always thought that air quality inside parking lots were suffocating. And now I have some proofs. I took a quick measurement with the CleanSpace Tag and left from there as soon as possible. 86.9ppm of Carbon Monoxide!!! Tragically there was a man without any kind of mask working inside this parking lot guiding drivers where to park.
Next week a complete review for the CleanSpace is coming. Stay tuned!
2017 New Air Purifiers in the market that use new ideas and technologies to clean the air from VOCs to PMs. As you can see on the green column I have mentioned the best and the cheapest way to improve air quality indoors, it’s a reminder for those that can apply this principle and when the outdoor air is cleaner than the indoor.
Prices may vary during time.
Some Companies don’t specify on their datasheets some of the infos.
There are hundreds of air purifiers out there I have just included some of them, if you want to suggest another one please feel free to mention it on a comment below and I will be happy to add it.
The classification of the design is based on my personal criteria, what’s aesthetically nice or not.
The Modular City Air Cleaner aka MCAC is a stracture-device made by a company called Vivex Engineering. Their aim is to alleviate cities from air pollution.
Well, we all know how polluted is the air in cities full of thin dust that are residual of rust, asphalt, tyres, rubber, various ashes, crumble of cement, stones and other more.
The MCACcan be realized in various shapes in function of the final destination of use and can be equipped with or without internal fans (in case of canalized applications). What is even more great about the MCAC is that has been designed as a power saving-oriented machine and it can be equipped with photovoltaic panels for energetic autonomy. It can be integrated in already existing structures as for example inside the beams of a bridge. The generator looks very compact size, has a pressure drop of about 10 Pa and has a very low power consumption of approximately 40W per1000m³/h of treated air.
The device uses the Cold Plasma technology which has the biggest effect against bacteria, viruses, dust. See the performance range table below.
The air crosses the plasma step and then goes to the scrubber step. There the air passes through water and the water is enhanced by substances taken off the air and is collected in a tank below. A complex automatic loading of clean water, periodically provide integrated water that is absorbed from the air due to evaporate and purge a portion of that contained in the tank. The purified air come out from the top.
The Cold Plasma generates by-products like Hydroxyl H and OH, Ozone O3, Oxygen peroxide H2O2 and Nitrogen Monoxide NO. The NO + O3 are converted in NO2 + O2 but as the company has implicated some additional filtration steps then the bad by-products of the cold plasma process are eliminated. For example when NO2+O2 passes through the washing step is converted in Nitrous acid HNO2 because it is soluble in water and remain inside a water tank where becomes Nitrite Salts, so the air comes out clean.
It performs very well with most of the air pollutants. In the table below you can see how effective is with dust particles PMs, Nitrogen Oxide NO2 and Carbon Monoxide CO.
This technology isn’t low-priced but it is affordable for governments and municipalities especially in big cities like Madrid, Milan, Paris, London, etc where air pollution is very high and citizens need desperately clean air.
