This is a good little unit and very quiet. I use the Hydro-Cell and the Demineralization cartridge and clean it once a week. It still grows mold like crazy even with distilled water. Don’t have a mold problem with anything else in the house and the unit is very difficult to clean (particularly the outflow) after the mold takes hold (easily in two days). Trying a warm mist unit next…

Nice size and well-thought out design

Really fantastic product. It is very quiet and easy to use. The sleek design is also good as it does not take up a lot of room. Well worth the price. I definitely recommend you spend the extra money for this high quality humidifier.

Died within 18 months, luckily, comes with a 3 year mfg warranty.

I’d really like to rate this at a 3.5. The build quality is suspect. I own two of these, the first died within 18 months of purchase. Luckily it is covered under a 3 year warranty. The nozzle doesn’t provide enough direction to the mist, which regardless of aim generally flows up from the humidifier. However, I like the demineralization cartridge, which eliminates fine white powder associated with hard water. It also looks nice, the blue light provides a night light and turns red when the reservoir is empty. The footprint is relatively small, I can place it on my nightstand without overcrowding it. It’s also very quiet. Would be a 4 star unit if I could count on it to last 5 years or longer.

Meets our need

This humidifier is good and we’re happy with it. It’s a little pricey though. But I paid the higher price for this one because of some (non-Amazon) reviews I had read. It has an automatic shut-off which is really important so it won’t keep going when it runs out of water. You can also adjust how much humidity you want it to put into the room, which is also important so that you will get enough humidity but not too much, because you wouldn’t want to cause mold in the room. I think one downside is the shape because it could tip over easily. But we compensate for that by anchoring the humidifier with tape onto the cart we have it on.

Awesome

I was looking for a humidifier to help ease dry itchy skin (VERY itchy) due to winter indoor air quality/dryness. This really did the trick. This is definitely worth the investment. I really like the texture of the mist… it really stays in the air and disperses nicely. It’s also very quiet, and the noise it does make is very soothing. The blue glow is also very calming, but can be shut off if you don’t want it. The filter and carbon hydro cell are very easy to use but only needed if you want to use tap water. If use distilled water you don’t need either filter. This is a great purchase I definitely recommend it.
