Not the first time I've heard about this and it makes sense. Sadly people mentioning things like this get censored / deplatformed because their opinions go against the government policy. Like this person in my country:

Some countries are boasting that their superior policies prevent the spread so the other countries should learn from them. I doubt it. While the difference of Sweden and nearby countries can be explained by the policy difference, It's hard to believe most Asian countries doesn't suffer that severely can be explained by policy alone.

Here is an air quality presentation by none other than Hey spokesman DHH:

I’ve been using Awair[0] for almost a year and I did found a few problems with my habits around managing air.

What problems did you find and how did you solve it? Do you feel the difference other than the numbers displayed?

1. The fact that the humidity is often too low where I am at. I got a humidifier. Before using this thing I had dry nostrils, but never paid attention to it. Now it’s better.

2. The way cooking affects pm2.5. I don’t have great ventilation in the kitchen, so I started ventilating via windows for a better air quality at home. I do not feel effects of this though.

3. How fast the CO2 levels are rising with closed windows. Since my childhood it was regular in my family to sleep with windows closed, and ventilate maybe couple of times per day. And in the summer time the windows were closed when the air was cooled with a conditioner.

It turns out, that in an hour with closed windows the CO2 level is already higher than what is considered healthy. Nowadays it seems like I can say when room needs ventilation without a sensor, just cause I feel the air is not "nutritious" enough. I do feel worse (tired, slight headache) when not ventilating.

This resource evaluates some sensors (not all) [1]. As expected accuracy varies even within MFG+model. It's important to be aware of and learn of the inaccuracies and learn from them (trends rather then raw numbers)
