Cool Moisture Humidifier

This Honeywell Cool Mist Humidifier delivers comfortable humidity to help keep throat and nasal passages hydrated.

Genuine Honeywell Wicking Filter A

This cool moisture humidifier works with Honeywell Replacement Filter A. Designed for optimal moisture output and inhibiting up to 99.99% of mold growth on the filter, this Genuine Honeywell Humidifier Wicking Filter captures minerals from the water and helps prevent the buildup of white dust. The updated version of the Honeywell Replacement Filter A features a blue pre-filter layer that helps capture large airborne particles from the air that passes through the filter.

Protec Antimicrobial Cleaning Cartridge

The Honeywell Cool Moisture 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.

Q: I hear the fan turning, but I don't see any mist. Is my humidifier operating properly?
A: Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no "mist" emitted. When operating normally, you will feel only cool air coming from the unit. Monitor the water level in your Tank/Base. If you notice a decrease in the Water Tank over 24 hours then the unit is operating normally.

Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A: First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture as your air is already saturated. Also verify the upper enclosure and water tank are properly seated.

Q: My filter has turned light brown and rust colored. Do I need a new filter?
A: Probably not. Since your filter has been made with Protec antimicrobial, the change in color indicates only a mineral deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect the humidifier's performance.

Q: My humidifier doesn't appear to be as clean as when I first purchased and/or I'm smelling an unpleasant odor. What should I do?
A: You probably need to replace your Protec Antimicrobial Cartridge. This cartridge helps your humidifier stay cleaner, longer and helps freshen the mist. If you have been using your humidifier regularly for over 30 days replace the Protec cartridge and follow the cleaning instructions.

Wish I could buy another!

I absolutely love mine that I bought last year. No visible mist, so I feel that the moisture is better dispersed in the room. I have never seen any sign of mildew or mold, and its so easy to clean! I wanted to buy one for my daughter, but they are out of stock! I sure hope they make some more soon!

Solid solution and well made

Easy to use, works very well, only gave a 4 because I haven't had it long enough to give a 5 since I want to see reliability/consistent performance in numerous conditions first.

Worth every penny

The tank is easier to fill than other models. It's also larger than most. When you fill it every day this makes a difference. I have to replace the filter about every two months because of the hard water where I live. Most tanks and bases are not dishwasher safe. This is another plus versus other models. If I can find any fault it's a bit bulky vs the last one I owned. The upsides are worth the trade off. Breathe better and bye bye dry winter skin.

Doesnt shut off when its empty

The price is good, but the fact that it doesn't shut off when it's empty is a problem. I fear it will put extra wear and tear on the motor. I am not there every day and therefore, can't monitor it.
