Uhm.. how?
"Shipping November 2018" and the order button is labeled "Pre-Order".
I'm a bit amazed - and disappointed - by how little information there is on that product page. The "tech specs" are size and weight and that's it, for this kind of product? Pretty much everything is missing that I would expect to know for this kind of product specifically. I even played the clip, still not a single piece of actually relevant information. The only sentence that says anything regarding the intended use is
> Flow measures real-time concentrations of NO2, VOC, PM2.5 and PM10: everything you need to understand your exposure and build healthy routines.
Given that they seem to target the "average person" they should probably explain somewhere what those abbreviations mean (I do, but what "average person" knows what VOC is?).
No way I would order given the lack of information, given that the price is $139 (or Euros).
After a quick search for similar products I found this comparison of several products (2016): http://energysmartohio.com/indoor-air-quality/which-indoor-a...
