On a tangent note: don’t use ultrasonic humidifiers. Unless distilled water is used, they create a shit-ton of pm2.5 particles. Use evaporative humidifiers (just disks with myriads of small notches for water to cling on and a fan): https://us.smartmiglobal.com/pages/smartmi-evaporative-humid...

How did we survive the last 3.5 billion years?

Also we died at a young age. Everyone dying at 40 isn't incompatible with the species surviving but it's what advice like that is usually trying to avoid (and even less extreme outcomes).

If you’re willing to use distilled water, ultrasonic humidifiers have their own advantages over evaporative.
I’m personally willing to buy distilled water. It’s a dollar per gallon, and we only need the humidifier during a short few months. You can even buy a small countertop water distiller for under $60.

The best solution I've found a few years ago is one Venta LW 45 for every 30 m² of space. That's enough to run them on the lowest speed while maintaining acceptable humidity and CO₂ levels. Higher speeds are too noisy. Smaller machines evaporate less. For sub-zero outside temperatures, it's necessary to add at least 5 g of water to each cubic metre of air coming from outside. The recommended ventilation rate of 30 m³…

Which venta are you referencing here?
I also have one and love how easy it is to clean.

We didn't have access to modern technology... like ultrasonic speakers? Also we died at a young age. Everyone dying at 40 isn't incompatible with the species surviving but it's what advice like that is usually trying to avoid (and even less extreme outcomes).

The concept of everyone dying at 40 is a myth/misunderstanding anyways - the reality was a lot more bimodal than that.
1. We've reduced infant (and childhood) mortality. My comment isn't talking about this effect but it did drag down average life expectancy substantially. Including this effect life expectancy at birth in the stone age might have been as low as 20... but as you say the bimodality means this is a deceptive statistic when used this way.
2. We've made it so you on average live longer even if you survive childhood, my comment is really just about this part of the effect. It's still a simplification because saying "on average if you survive childhood you die at 40" isn't the same as "everyone dies at 40" but closer to "adults die at all ages in a reasonable smooth monotonic curve and 40 is about the average age they live to but some get lucky and live to 80 or whatever". But then "don't use ultrasonic dehumidifiers" is like this too, using one won't kill you at some specific age, it will just slightly increase your chance of death every year for the rest of your life however long that ends up being.
The number 40 was picked out of a hat, too. It should be right for some areas at some times just by coincidence though and since I was non-specific that makes me right ;)
