Roger: Hi Suzana, I heard that you are working on air-pollution-related projects.
Suzana: Hi Roger, yes. Got some issues with air pollution?
Roger: Yes…my kid recently got some respiratory problems. I am planning to have air quality monitors at home. Just saw some promotion online selling monitors at € 100.
Suzana: At € 100?! What kind of parameters is it measuring?
Roger: Um… I am not quite sure. It tells it’s the best seller, with high accuracy, easy to use… and some LED lights showing air is good, moderate and bad…
Suzana: Oh! That looks good. Did you consider the parameters measured, and their certified accuracy? How easy it is to see full history anywhere, anytime? Does it show the health impact, or is it an obscure quality score?
Roger: That many?! It is more than just a machine showing green light…. Can you tell me more about each of the factors?
Suzana: Yes, sure! It is important that you know what you need and what you are going to buy. Otherwise, it is a waste of time, money and resources!!
