Excessive noise

HoMedics UHE-CMTF91 Is Making Excessive Noise

For the UHE-CMTF91, HoMedics lists two first checks: make sure the unit is level and make sure the water level is not low.

White dust

HoMedics UHE-CMTF91 Is Leaving White Dust

White dust is mineral residue from hard water, not a humidifier defect. Use distilled water and replace the demineralization cartridge as its performance declines.

Peculiar odor

HoMedics UHE-CMTF91 Has a Peculiar Odor

A new-unit smell can be aired out; an in-use odor points to dirty or old water that should be emptied and replaced.

Stops at humidity target

HoMedics UHE-CMTF91 Turns Off at the Humidity Setting

This is normal humidistat behavior. The unit turns off when it reaches the set humidity and resumes when room humidity drops about 5% below the setting.
