Protec Antimicrobial Cleaning Cartridge

The Honeywell Ultrasonic Cool Mist Humidifier can also use Protec Humidifier Cleaning Balls. Protec Antimicrobial Cleaning Cartridges feature a patented antimicrobial, Aquastat that continuously works to hinder the growth of bacteria and mold. They're also capable of preventing the buildup of slime in the water and humidifier surfaces. Protec Antimicrobial Cleaning Cartridges work in all humidifiers and are safe/non-toxic. Aquastat contains no harsh chemicals or harsh acids making the cleaning action just as gentle as water on your humidifier surfaces and components.

How do I clean my Honeywell Ultrasonic Cool Moisture Humidifier?
For ultrasonic humidifiers, periodic cleaning of the nebulizer will help it perform at its best. The nebulizer, which is a round disc found in the base of the unit, vibrates at ultrasonic speed to create mist. Over time, minerals from your water may collect on the nebulizer causing it to slow to a pace that is not enough to create mist.

Turn off and unplug the humidifier. Empty water from the tank and base of the unit. Fill the base with undiluted white vinegar (just enough to cover the nebulizer) and let it soak for at least 20 minutes. If you see a strong mineral build up, you may want to let it soak longer. Do not run the humidifier with vinegar in it. Gently wipe nebulizer and reservoir area with a soft cloth to remove the mineral deposits. Empty the vinegar and rinse the base with water until the smell of vinegar is gone.

Love it!

Love this humidifier! Bought it brand new at my neighbors yard sale for $10, but I would’ve paid full price for it knowing how good it would be for my little room. Kudos to you guys!

Simple product, works so far

Well-designed, I suppose. But more just simply built. Few moving parts means less to break.

Works great so far

Works great so far. Don't find it to be loud at all, as some have complained about.
