> Conclusion: [...] However, the defined cut off values for the air quality and its description as “Good”, “OK”, and “Not Good” are not based on science or international recommendations and create the false understanding that the air is good, when in fact it is not good at all.
- jansan 5y agoConsidering that the article was basically written by somone who is selling competing products I would take this statement with a truckload of salt.
- colechristensen 5y agoI’m not selling anything and unless the writer is outright lying about the number ranges, I agree with them. The “green” range is way too lenient and the sensor will only help you keep away from really terrible air quality, most people would have it green always while doing nothing at all.
- jansan 5y agoAs I understand it "yellow" will indicate better air quality than "Unhealthy for Sensitive Groups" according to the US standard. I see a difference between "Unhealthy for Sensitive Groups" and "really terrible air quality" as you describe it.
- colechristensen 5y agoThere's acutely unhealthy for sensitive groups and there's long term unhealthy for anyone. Convincing reasons exist to think that significantly lower levels than are acutely unhealthy have long term health impacts. On top of that, you don't really need a sensor to know whether or not your air has particulate levels that are acutely unhealthy, you just know it. If you don't care or only want to know if your air is quite bad, sure, buy one of these. I don't think it's a reasonable level, but you do you.
