Customers are saying

Customers are satisfied with the Ultrasonic 2 Gal. Warm and Cool Mist Aromatherapy Humidifier's large tank size, quiet operation, and ease of use. Many appreciate the humidifier's ability to produce a great mist, along with features like the night light and timer. While some find refilling the large tank cumbersome and the unit heavy when full, the positive aspects outweigh these minor drawbacks for most users. The aromatherapy function is also a frequently praised feature.

    I purchased this to keep the humidity in my bedroom up while recovering from a tonsillectomy. One of my favorite features is the movable spout on the top. I was able to position it from my nightstand to have the stream coming out to fall right near me. I also like the light option. I had to wake up every hour to drink water and keep my throat moist. It gave me just enough light to see my water bottle but wasn't so bright that it kept me up. Now that I have recovered enough to not need it every night we moved it to the living room and could feel the difference. It is a little clunky to fill but well worth it to not have to worry about it running out of water. All in all it was a great purchase and I am very pleased.

    Excellent humidifier, large tank, very quiet, easy to install. The mist can be set to warm, but when it spreads into the cold air, it just quickly becomes cold. Not an issue for me though. The only minor thing I wish they could improve is that the tank is a bit heavy when filled up.

    This device appears to have 6 settings (l,m,h) plus one more of each for warm mist. The warm doesn’t feel warm like a sauna but seems to produce a little more mist at least for the low setting which is all I use. I also use the warm setting to encourage the mist to hang in the air rather sink to the ground. Not sure if this is all in my mind. Low setting with warm mist is enough to raise the humidity level a few points for me. If it floods and no mist is produced when the unit is turned on, the instructions manual says to remove some water, which works but is tedious. I found that you can just leave it running and eventually the mist will come. The biggest design issue to me is the offset handles which make carrying/handling the tank awkward. Feels like I’m going to drop the tank loaded with water one of these days. Drop one star. Can’t say anything about reliability yet. Considering that Doctor Who’s Pompeii episode had people turning into stone for breathing volcanic dust, everyone using ultrasonic humidifiers will eventually turn into white statues. Get into a good pose when this happens.

    I have been using this humiidifier for approximately 3 weeks now. It is very quiet and easy to refill. I have only filled it up halfway and it will humidify for hours. I placed it in our large dining/living room and it is more than sufficient. Instructions were easy to follow. I have not used the aromatherapy yet. Waiting to find the right scent.

    Works great! Full tank on the high setting lasts ~12 hours, which is superb, and ~30 hours on low. Haven't used the aromatherapy option yet, so can't comment. If I needed two, I would get another one of these.

    Pros: Large tank for longer time between refills. Quiet no noise operation. Cool or warm air usage. 3 speeds. Cons: Leaves white dust on everything, even with the purchase of recommended tank filter. Tank filled with water is kind of heavy.

    My wife and I bought this for our newborns nursery. We personally have owned four different humidifiers in the last two years simply because they didn’t work well or ended up being challenging to clean thus becoming unsanitary. When building our new nursery we knew we wanted something silent, with amazing functionality. This humidifier hit it on the head. The fact that you can alternate between cool mist and warm mist is great for a nursery where a little one will begin to move around and you want to switch it to cool mist while they’re active and warm mist at night. All of the other features are amazing as well!

    Wonderful Humdifier. Very quiet, no mess and will run for 24 hours. I got it as we had Covid and wanted to have the air from it. It comes wiht a defuser where essential oils can be used. I really love the way it lights up. I am so glad I purchased it.

    It is very quiet and produces a nice mist. The options are very good. However, refilling is a pain. It is hard to hold onto. It is very heavy after refilling and drips water all over.

    Been using this humidifier for the past few weeks an it works well! Very quiet and efficient. Huge tank and seems to last forever. So far no white dust. I did use sediment cartridge, not the one from guardian but Ai O Swiss which fits beautifully and works better for whit dust than the oem cartridge

    I have been looking to purchase a humidifier and noticed this one on sale. I have been pretty pleased so far. The only part not enjoyable is refilling it as I am using eight hours nightly. But so far I give it a thumbs up overall!

    I bought 2 units that we use to fine mist essential oils for health reasons - usually frankincense and eucalyptus - 1,000 times better than other diffusers and lasts forever with one filling. Best purchase to date.
