No visible mist

Honeywell HEV615 Has No Visible Mist

That is expected for the HEV615. It is an evaporative cool-moisture humidifier, so the fan moves moisture from a wet wick without producing ultrasonic fog.

Honeywell HEV615 Has Low Humidity Output

A hard, crusty, odorous, or mineral-loaded wick can reduce output. Honeywell recommends wetting/flipping the wick and replacing it based on condition and use.
