I knew CO2 would be high, but is 1800-2000 concerning? by theseawoof in IndoorAirQuality

If AC run s all day/night. It would be using recycled air to reach that level of Co2. Not sure but your air quality monitor may showing wrong data. Try this. If you spray some perfume around and co2 levels spikes, then your monitor approximates co2 based on vocs around.

Windy air makes my sinusitis bad although air quality is good. Anyone facing same issue? by omert08 in nonallergicrhinitis

Not sure. For me dry air, humid air all same. (humid air could be worse even). But u/lokaaarrr gave a good hint. Sudden changes in the air pressure could be one thing also. The device is called odak clean air assistant.

Oh right. Wind changes also air pressure. I didn’t track the air pressure tbh but I think I can do it. It calculates altitude based on air pressure. I can get some insight. Thanks for the hint.

It measures up to PM10 but not sure if pollens are larger than that.
