They do mention that CO2 levels are typically higher indoors and that Americans spend 87% of their time indoors, but it would have been interesting to see a prediction for how much sooner this would become a problem inside.

Modern houses are actually quite a problem for this. A well insulated house also tend to be quite well sealed. I’ve seen my bedroom pass 5000ppm. I suspect a lot of people are working in 1000ppm environments or higher for long periods.

For those interested, IKEA recently released a air quality sensor that does CO2 for a very low price. ALPSTUGA

What do you even do about CO2 in that scenario. I can monitor it and collect data, but addressing it feels like a losing battle, especially in winter.

My plan is to replace the bathroom extractor with a heat exchanger. It takes outside air, warms it using the exhaust air, then dumps it into the bedrooms.

The living areas are easier. Opening a window for 10 minutes isn’t an issue when you’re awake and moving about.

You can also get vent replacement versions. They flip flop between venting out, and pulling in, storing heat in a heatsink as appropriate.
