Customers are saying

Customers love the Ultrasonic 2 Gal. Warm and Cool Mist Aromatherapy Humidifier for its large tank size, quiet operation, and ease of use. Many appreciate the adjustable mist settings, overall performance, night light, and timer features. While refilling can be a challenge and the unit is heavy when full, users are happy that there are no filters to worry about.

    Excellent ionizing humidifier!

    Excellent humidifier works great! My only dislike is not the product itself, but all these newer humidifiers use an atomizer technique so the vapor comes out cold and super fine particles which quickly fills the room with a smoke like fog. I wanted a humidifier not a FOG machine! Not only is this annoying, but everything in the room gets covered with fine particulate moisture causing any dust in the room to stick to EVERYTHING leaving a fine white dust coating. Due to this, we literally have to clean glasses, phone tv and computer screens, desktops, furniture, after every couple hours running the humidifier. See example picture attached, I cleaned my keyboard obviously to use it for this review, but take note of my Galaxy Watch 5, desktop, monitor and laptop covered in moisture and dust. We never had this dust problem prior to getting this humidifier and another brand in the kids room next to ours. I will say it has greatly improved our breathing, I suffer from constant stuffy nose from dry air, we live in Las Vegas in the desert, but after getting the humidifiers and running them near 24-7 I can breathe freely no stuffy nose! Another odd thing is the fog coming out of the humidifier smells like PEE (from both brands humidifier), and our rooms now smell like a urinal. I do not believe this to be fault of the humidifier, but maybe of the city water. Unfortunately as far as I know you can add anything to the water to neutralize the odor without ruining the humidifier ionizer. The machine does come with a small compartment to add a few drops of essential oil to a small sponge, but its soo small you cant even notice the essential oil scent in the air. Keep this in mind when deciding to get this type of humidifier.

    It is a nice size but not easy to fill. You have to remove the whole top and turn it over to put the 2 gallons of water in it. It is easy to fill at that point but I always spill some water because of this and it is heavy when full. You have to flip it over to put it back together. Just a bit awkward. It would be nice to have it fill from the top for one this size. One can also add essential oils in a specific place wish is nice. It comes with one cardboard for this and would nice if it came with a bunch of them so you could change out the oil without the hassle of figuring out how to buy more. It is quiet and easy to use. Does last longer depending on the setting and time you use it for.

    Best purchase of the year. I bought one for me and for my daughters home. Quiet, easy to use, lightweight, makes it easy to breathe with all the heat right now in our homes.

    Does a good job of adding moisture to the room when set to high. Water storage unit takes a lot of water which lasts a couple of days and is heavy when full. Need to use caution when refilling as does drip when taking the water storage unit off. Runs nice and quiet. Slightly on the expensive side.

    Like the warm mist/cool mist feature, base is light weight, ultra quiet (except for the occasional glug glug), and has an antibacterial feature. The top is heavy when filled to capacity but overall, I am satisfied.

    good humidifier, quiet, good size tank. drips when you try to refill blows a lot of mist so keep it on something plastic (not carpet) and don't direct toward anything you don't want wet

    I like how it holds 2 gallons of water, however it is not easy to refill. It can be messy and spill water when moving to refill. There is no humidity level monitor but it does have a timer and a night light.

    Ran humidifier with soft tap water. Horrible white dust everywhere. Bought the filter to capture some of the minerals. Really didn't make much of a difference. We are now using distilled water in addition to the filter. It is now running clean. Puts out nice mist. We only run it about 4 hrs per day to maintain humidity level. Very quiet.

    It works! I had another humidifier and it didn't feel like it did anything. The dry air really makes it hard for me to breathe at night. Putting this on the 4-hour timer before going to bed is perfect! At first we were leaving it on all night at full power and we'd get a white residue on everything in our place, even outside our bedroom. It's also important to clean this thing every week. Going 2 weeks without cleaning it makes the vapor start to smell.

    Decent Humidifier

    A pretty decent humidifier. Best Buy price matched for me and saved $50. The warm mist function doesn't really give warm air, but other that that works great. It does tend to dribble a lot of water when you detach and reattach the tank during filling, wish this had a top fill option. Tank holds 2 gallons and does get heavy if you fill to capacity but lasts a long time.

    Nice humidifier. The addition of being able to add essential oils is really great too. It was a good deal at Best Buy and had good reviews an various websites. You have to be really careful so it doesn’t mold. Other than that, it’s a great humidifier. The heat settings are good and this puts out a ton of vapor on high. The nightlight is nice for kids too.

    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.

    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 have a very large bedroom and, during winter months, frequently wake up to a sore throat and dry sinuses. I run this product for 8hrs (on HIGH), about 6-8 feet away from the bed. I am now free of the dryness. Running it this way will last 2 days on a full container. My only compliant: the dripping from the water container during refill. To be honest, this is probably an issue with every humidifier but water will also drip out of steam dispenser when turned upside down for refill. It's not excessive but just enough to be frustrating. That being said, it's still a great humidifier. I would have given it a 4.5 star if I could.

    Seems like a nice humidifier. Nice big 2 gal. tank but because of that I would think it would be awkward and difficult to fill for smaller people. I am a healthy, athletic adult male and even I think its heavy and hard to handle when filling it up and when its full. You have to remove the tank, remove cap on bottom and then fill. Would not recommend for smaller people. Just trying to help your decision
