Red light on power dial

Pure Enrichment MistAire XL PEHUMLRG Red Light Is On

On the MistAire XL PEHUMLRG manual, a red power-dial light means low water. Unplug and refill the tank.

No mist / humidity

Pure Enrichment MistAire XL PEHUMLRG Has No Mist

For this ultrasonic model, no mist is not normal. The manual points to power, tank installation, and a dirty ultrasonic disk.

Air blows but no mist

Pure Enrichment MistAire XL Blows Air but Produces No Mist

The XL manual separates this from a total no-power/no-mist state: check excess water in the base, residue in the tank, the ultrasonic disk, and very hard water.

Low humidity output

Pure Enrichment MistAire XL Humidity Output Is Low

The manual points to a dirty ultrasonic disk or water that is too cold when humidity output is low.

Bad smell

Pure Enrichment MistAire XL Humidity Smells Bad

The XL manual links a bad smell to poor maintenance or dirty water. Clean the humidifier thoroughly and refill with fresh water.

White dust

Pure Enrichment MistAire XL Is Leaving White Dust

Hard-water minerals can be dispersed as white dust. Use distilled water if the problem persists and keep the unit descaled.

Water around unit

Pure Enrichment MistAire XL Has Water Around the Unit

The manual first points to over-humidification, unlevel placement, or mist aimed too close to nearby objects—not automatically a cracked tank.

Increased noise

Pure Enrichment MistAire XL Is Making More Noise Than Usual

The XL manual says the unit should be on a flat, level, hard surface and not on a soft or absorbent surface.
