Nice, compact humidifier - 04/11/2018
Reviewer: Charlene Fluder
So far have only had it about a week now this humidifier does just what I need it to do---increase humidity in my hallway where my classical guitars hang on the wall and kitchen. It's easy to use and will be easy to clean, given the simplicity of its design.
Works for me! - 04/11/2018
Reviewer: Joan McDougall
Had a problem with my ultrasonic humidifiers: new cat was knocking them over. So decided to try an evaporative humidifier and this one looked good on paper.
It's quiet, even on the high setting, and I no longer have headaches from dry air--which is the main reason Ive had humidifiers since the 70s. It looks good and while the cat occasionally moves it, most of the time he leaves it alone. The only problem is the tank is on the small size and I have to frequently refill it. May eventually get a larger one, but will most likely get Honeywell again.

I've been using Honeywell products for a long time and I've never had any problems with their products. This humidifier has the easiest mess free water reservoir to fill & cleaning & changing the filter is a breeze. it's so quiet and works so efficiently...

Love these humidifiers. They are so easy to clean and they work really well. Our humidity hasn't dropped below 60%.

Solid and effective - 01/21/2018
Reviewer: James Clark
It humidifies our 288 sq. ft. bedroom well. Highest fan setting is noisy, med. is white noise, low is almost silent. We use it on med. Nothing to say on reliability as we have had it only a week.

HCM-350B - 12/21/2017
Reviewer: Stephen Sager
I bought this Humidifier because I was having problems with my eyes going dry at home. Eye drops were not enough. It made a difference the first night I used it. The machine is very quiet to me on high for when I put it on low I cannot even hear it. It works very well for me.

The Honeywell 350B humidifier is very effective at improving humidity levels in your home during the dry winter months. Mine has made a big difference in the comfort of my home.
Very quiet! - 12/11/2017
Reviewer: Candace Gregoire
I bought this for my bedroom and it works very well, keeping the humidity level between 40-50%. The tank is very easy to fill and has a large opening for cleaning. I run it on low at night and can hardly tell it's on, it's so quiet. I run it on high during the day and will use most of a tank of water. I've only had it for a couple of weeks now, but so far, I am very happy with this unit.

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.
