Accurate.
We bought this to test the air in our homeWe have tested it in a few places, both inside and outside and the measurements are very reliable.We have also tried to create changes in conditions: like opening the window when we knew the air outside was rather polluted or turning on the air filter in the room.In all these situations this detector was very sensitive to the changes and reflected accurate values.

Interesting device at an acceptable price.
The manual advises to use 8 minutes for calibration. However formaldehyde and tvoc turn to zero much faster. Hence I now just wait for the HCOH and TVOC to zero. 2.5pm tends to stay on 3-4 whilst calibrating. Initially it read tvocs in two bedrooms (400-480) at almost double the value of the living room but still within acceptable range. However after 15-20 minutes, after measuring some other rooms this could not be reproduced. What strikes me is the HCOH remains low but TVCO is somewhat raised. As with most of these devices one wonders about their accuracy. Are there any regulations regarding their efficacy they should adhere too?

Very bad product, waste of money!
Terrible! Returning this product as we speak! It did not last for longer than hour when turned on.
