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...

Alec from Technology Connections also has a great video comparing humidifiers here

That Smartmi model seems to have toxic IoT in it.

I'm currently using the Vornado EV100 non-IoT evaporative humidifier, and my only complaints are relatively minor, as humidifiers go (consumable wick, fan noise, insanely bright blue LEDs). https://www.vornado.com/shop/humidifiers/evaporative/ev100-e...

You don’t need to connect it — works completely offline.

Also no consumable parts there: just plastic disks which you clean with couple of spoons of citric acid dissolved in water from time to time.
