Customer Reviews
TotalComfort™ Cool Mist Ultrasonic Humidifier is rated 3.2 out of 5 by 10.
Rated 4 out of 5 by from Nice Little Humidifier I am really happy with this little guy! Easy to fill and operate. I like the night light feature and auto shut off when the tank is empty. It's perfect for a small bedroom. The aroma therapy tray/pad great as well. I put a few drops of lavender oil on I me of the pads and it filed my room with a relaxing fragrance. The instruction manual is very easy to understand. I deducted one star because after 4 days of use the "Clean Me" light is already and I don't have particularly hard water. Overall I am very pleased and would recommend this product.

Rated 1 out of 5 by from Miss Debbie I purchased this exact humidifier today. When I got it home and read the pamphlet, wanted to be sure the top came off before I put the filter in water for 10 minutes. It said turn counter clockwise. I tried for a while, at least 30 minutes. Then, I thought maybe the top lid should come off by turning the other way. Finally I called 1-800-466-3342. They were closed. Hours 8:30 am until 5:00 pm Monday thru Friday. You would think this company had better hours. So I figured I would attempt to exchange it. I brought it back to the store and picked up another one to see if I could do an even exchange, and the store agreed. There were two other people including a manager whom once I saw him pop the cover off in frustration and that broke to no surprise. Really, and this was a male. No one could figure out including me why the lid does not screw off as it states by turning it counter clockwise . As it stated afterwards the lid goes on by turning footpaths right. So no I waisted my afternoon, and gas. Very glad I walked away. Very unfortunate. As two of this same product, and 3 people after reading instructions should have been able to get the top lid undone. I am having to input that I used this product. I never could, I tried two of the same product and has same problem with the lid. Or top that us suppose to screw off, and then turn right to tighten.

Rated 1 out of 5 by from Won’t stay on I bought this humidifier less than a day ago and am already regretting it. It won’t stay on longer than an hour regaurdless of the timer. Also the cleaning indicator light is already on despite using distilled water and not even going through an entire tank. Thoroughly unhappy.

Rated 4 out of 5 by from Not silent, but quiet enough This product has roughly a 1 gallon tank, not the 5 gallon tank HoMedics states on there website. Despite there false advertising, the features on this product still were enough for us to purchase. It works as advertised, provides a nice mist that does not get area wet around or underneath the humidifier. The feature I most like is the timer. Set it and forget it with the auto shut off. One word of advice, if you have hard water, you will see the red light indicating clean the filter come on frequently and you will have to reset roughly every three days. Not hard to do, and it does not affect the machines performance, just a pain to do.

Rated 5 out of 5 by from Perfect size & isn’t an eyesore I bought this a month ago and I’m loving it. If you’re confused- READ THE MANUAL! It’s extremely straightforward. It isn’t awful to look at and it’s really easy to refill. I would definitely recommend this!

Is "5.0 gallon / 2.0 L tank" a typo? 5 Gal???

Asked by: DouglasS
I saw that too and thought the same thing. Amazon has the same one and it states 0.5 Gal....But if you do the math, 2.0 L does in-fact equal approximately 0.5 gallons. I believe it is most definitely a typo.

The water just keeps coming  out of the mist hole when I try filling it with water

Asked by: Carebear
Carebear, Don't fill water into the hole you see when you turn the tank, instead turn hard the cap that has Spring on it. Once you get that cap out, you can fill water from there and put the cap back. The instructions are terrible. They assume customers will risk turning that cap the first time as it's freaking soooo hard on my unit that I was worried I will crack it.

Does it have a filter?

Asked by: DisneyGirl
The humidifier uses a demineralization cartridge that is placed inside the water tank.

what is the transducer? how do i clean it?

Asked by: rile
Remove the water tank from the humidifier base and set aside. Pour out any remaining water inside the water reservoir. Clean the transducer/ultrasonic membrane with a 50/50 mix of white vinegar and water on a cotton swab. Wipe off with a damp cotton swab. Press and hold the clean button for 3 seconds until the clean light turns off. NEVER touch the transducer/ultrasonic membrane with your fingers; the natural oils in the skin can damage the surface.NEVER submerge the base in water or any other liquid.

Bought mine today, plugged it in. Pressed the power button......nothing! Pressed the power button again....nothing. Thing won’t turn on. Tried multiple outlets. Appears to not work at all. Am I missing something? Plan on taking it back as defective.

Asked by: Bry Guy
We are sorry to hear this. Press the power button once to turn the humidifier on and the humidifier should begin operating at low mist. Press the power button a second time to select high mist output. If the humidifier is not turning on, please return to your place of purchase for exchange or refund.

Just got this today. It was working fine. Now it shut off after a few minutes even when the timer is not set and the water tank is full. I checked the power source and everything. Why does it do this? Is it defective?

Asked by: Lauriegia
We are sorry to hear this. Please contact Consumer Relations at 1-800-466-3342 for assistance.

how do you fill the tank without all the water pouring out the misting hole at the top???

Asked by: anotherLIsa
Remove the tank from the humidifier base. Turn the tank upside down and remove the tank cap. Fill the water tank with clean, cool (not cold) water. We recommend using distilled water if you live in a hard water area. Never add essential oils or any other additives into the water tank or water reservoir. Even a few drops will damage the unit. Replace the tank cap by turning to the right until tight. Flip over, and place the tank back on the humidifier base, making sure it is firmly seated.
