Airgradient Avaliações 4

Very hard to connect with their minimal instructions. The machine is inaccurate: Finally reported PM 2.5 particles as "1" when local government ACI said the number was 39 and my Dylos recorded 42. The temperature and humidity was also off by 5 points temp (Airgradient 78 vs local therm 73deg; Humidity also off a few %) Elsewhere there is a warning that the company purchases a Chinese PM2.5 indicator which frequently reads only "1"--so this may be a known problem over a year old and unfixed!! I bought it specifically to track PM 2.5 due to relationship with lung disease and long term risks.

I see why they refuse returns or refunds.. I am sure that lawyers have a term for their behavior??

It took a little bit of tinkering to get it going. - nothing short of awesome.

We did have one issue with a product not being as described (not assembled even though paid for assembled version); however, they did fix the issue with responsive customer service.
Their products are innovative and serve an important function. We have more than one brand of AQI monitors and Air Gradient's products are shown to be accurate using these as well as the ones provided by the US Government.
Recommended company.

If you need any kind of support, do NOT buy airgradient devices.
They have tons of excuses and then they disapear instead of replace a malfunction sensor for 10$.
If you live anywhere, where it's below 0 degree celsius, do NOT buy airgradient devices.

It shows 0 when it's really -4 outside, so if you trust the outdoor device.
Things will freeze and get destroyed!
Indoor devices seems to work at least!
