Works great so far! I didn't want to purchase a humidifier that I had to change the filter and I didn't want to refill it too often, so this was most certainly the best choice! I keep it in my reptile room, snakes love it!

operates very quietly, does not keep us awake.
bottom fill water tank slight disadvantage, heavy to turn over and carry.

I think it's a really a great humidifier. It's our first humidifier, and it's by far the best! It's super quiet, it's on all night. I love the fact that you can turn the LED night light on or off, so you don't have to be covering it with a towel. All of the functions / buttons work great, they're just enough for what's needed - a low medium or high setting, cold/warm, etc. My favourite part is the double nozzle that you can turn so the vapour can go in two directions! Covers the room faster and it's not concentrated in one spot. You see this especially if you have it on a medium or high setting. This is a really really great feature.

Having bought two previous humidifiers, one with filter and one without, this is the best on we have so far. The noise is minimal, the lights are adjustable and very pleasant and the humidifying is just right. I do use it for my toddler's room so I have to place it on the floor since I fear placing it on a higher surface might encourage her to tug at it and topple it over. Otherwise, it is just what we needed to control the effects of allergies.

Bought this humidifier to use in the bedroom at night. Works very well and is extremely quiet. The chrome on/off switch is very smooth making it difficult to turn. Water reservoir is large, lasting about a week between refills.

I am a chronic allergy/sinus sufferer and was badly in need of a good humidifier for the winter months in Southeast MI. I live in a house that has forced air heating and the air can get VERY dry and cause my sinusitis to flare up causing poor sleep and air quality in my house. I use this product in a medium-sized bedroom (12x18). After doing some homework I landed on Germ Guardian product to help with my problems.
First i'll spell out the pros of this product:
-VERY quiet. Even it's highest setting it is barely a whisper in any room you're in. The ONLY noise you will hear with this device is an infrequent gurgle from a water bubble rising to the surface in the tank. Again, VERY QUIET.
-Large 2.4 gallon tank should hold you over for 3-4 days depending on level of humidification needed. The tank itself is not that hard to fill either, unlike some of the clumsier tanks i've dealt with.
-Small footprint. This device will sit well on any small cabinet, table or shelf.
-Ultrasonic humidification emits a steady stream of humidified vapors but they do not leave behind any white residue or particulate like some wick and/or filtered humidifiers. It works especially well with our osmosis purified water.
-Control stream of mist easily. This device can emit a fairly concentrated stream of mist. Luckily you have a full 360 rotation and can also split the strim of the emitting aperature. Handy if you have to place the device near other electronics or moisture-sensitive items.
This product is not without a few drawbacks, but they are minimal:
-The adjustment indicator is analog - meaning there is no digital indicator to set your humidity level at. It may take some trial and error to get it just right for you.
-Cold and Warm mist feature does not work all that well. In order for you to get the warm mist to be consistent you must run the device for a long period of time. After 2-3 hours of operation the mist will start to feel noticably warmer on your skin. The cold mist is cold...
-Extremely bright LED power light on front of the device. You can remedy this simply by putting a piece of masking tape over it or turning the device around.
-Cleaning is a bit tedious but nothing too intense. You can easily clean the tank and the unit in less than 10 minutes.
I have read some other reviews on the product before purchasing and most read similarly. One claim I have noticed is that this product claims to humidify a 700sqft room but does not actually have the capacity to do so. I do not use mine in such a large room so it is not an issue but be aware.
All in all I am extremely pleased with this product. I would recommend for anyone with similar needs.

Quiet, efficient, large capacity and great look make this a superb product. Low to no maintenance a big plus. Highly recommend to those who get dry skin in the winter.

I've been through my share of humidifiers including a smaller model by this same company which didn't last very long. I've had this one for a few weeks now and it works great! Easy dial control to set the amount of moisture you want in the air. The water tank is large enough to last for a few days. Let's see how long it lasts..

This is the best humidifier I have found. I love the fact that it does not use filters and is very quite. It was more than I wanted to spend, but was able to purchase as a "deal of the day" for $80. My only complaint is that the tank is hard to manage when filling.

Powerful humidifier with high capacity.
Fan is too weak, so moisture builds up on surfaces near humidifier.

We use it in our family room and it increases the humidity to about 40% in the winter. We use it on the cold setting as the other does not provide much warmth.

Even when it runs out of water it will turn itself off. My house is static-free with the extra humidity now!

Great for 1250 sq ft

This reviewer received promo considerations or sweepstakes entry for writing a review.
I purchased this as a secondary unit for my 1254 sq ft condo. I like to run one on one day and the other on another to fully allow to dry in between so the units don't get stinky. For my space, this one is great!
Pro:
holds a lot of water so I don't have to consistently fill up
humidifies well--the occasional shock in different rooms are less frequent
very quiet--if it wasn't for the mist, I wouldn't know it's on
Con:
I hate that it doesn't come with the optional decalcification filter or water cartridge, which I'd be more opt to replace if it was
the opening is too small for me to get in/clean inside of tank. If opening was a bit larger, I could stick my hand in/clean occasionally.

I really like the mulitple settings and how quiet it runs. The automatic shutoff is a wonderful idea.
The only draw back is how the way it refills.
After you fill it tank, you have to turn it over to to put it back on. Its kinda heavy if you fill it full with water.

So far FANTASTIC

I don't know how well it lasts since I've only had it 24 hrs. The mist coming out is as good now as it was when I plugged it in. It's quiet and the night light is great. I have sinus and lung trouble so having this in the room I'm in most often with the doors closed has helped me already. I just wish it had a medicine cup so I could use my essential oil that helps me and my asthmatic dog breathe easier. Great product so far and I'm so glad I bought it.
