Water vapor from a humidifier seems to raise PM2.5 level. Even with an air purifier in eco mode overnight.pic.twitter.com/zLY8i9o903

Lazyweb to the rescue: ultrasonic humidifiers eject small droplets, which are detectable by some particulate sensors. Said droplets may also contain minerals, which will be left behind when they evaporate. Ditto may contain mold or bacteria if you do not maintain the humidifier!
Tips are: use distilled water, replace daily, clean twice a week.
No idea if the minerals are of particular (
) concern. But my random-ass guess is they would presumably re-dissolve easily, and not get all up in your bronchioles like soot? Very much a guess tho.
Shouldn't they fix it under warranty if you can reason that it's a manufacturing error? It probably depends on how strongly the law protects consumers in your country.
