Pure Enrichment PEHUMIDIF Has Low Mist Output
Scale on the ultrasonic disk can reduce mist output. Pure Enrichment recommends cleaning/descaling rather than scraping the disk.
Pure Enrichment PEHUMIDIF Is Leaving White Dust
Hard-water minerals can create white dust on this ultrasonic model. Distilled water is optional but can reduce mineral precipitation.
Pure Enrichment PEHUMIDIF Is Leaving Water Around the Unit
First rule out excessive mist output/room saturation and placement before assuming the tank leaks.
Pure Enrichment PEHUMIDIF Mist Smells Bad
Treat a stale or musty mist smell as a cleaning/water issue first: empty old water, clean the wet parts, rinse, and refill with fresh water.
Pure Enrichment PEHUMIDIF Needs Cleaning Too Often
Hard water can shorten the time between descales. Pure Enrichment recommends rinsing/air-drying between uses and says scale removal may be needed weekly or every other week.
