Pure EnrichmentHUME Ultrasonic Cool Mist Humidifier - Easy-Clean 3.5L Tank Lasts up to 50 Hours; Whisper Quiet, & Auto Shut-Off for Large Living Rooms, Basements, Bedrooms, Nurseries, & Plants

This is a great little humidifier. I was looking for an effective, quiet, easy to clean humidifier that has no filter. This was it. It puts out enough humidity (that I measure with a separate humidistat placed across the room) for our bedroom. The tank has lasted all night on high except one night when it was extremely dry in the house. I usually only need it on medium. There is one simple dial for controlling the humidity, which I love because it is a humidifier - I am not trying to land an airplane. It is almost completely silent (I had an evaporative humidifier that I recently threw out because it was way too loud). It is easy to fill - you take the top off, fill it, and put it back on. The only improvement I would suggest is that the light on it is way too bright for a bedroom.I put something in front of the light and that helped. I am still rating it a 5 because it actually works, is easy to clean (no filter embedded with chemicals), it looks great, and it is quiet. The design on it is nice enough that I bought another one for my great room.

First and foremost, the Hume Ultrasonic Cool Mist Humidifier is very quiet – silent, in fact. This is a beautifully designed, well-constructed, high quality humidifier. In addition, the Hume Ultrasonic Cool Mist Humidifier adequately humidifies our 13’ x 9’ 8” home office during the dry winter months. I also appreciate the humidifier’s ease of operation along with the simple cleaning and descaling procedures. If that wasn’t enough, the Hume Ultrasonic CoolMist Humidifier also has the option for a humidifier decalcification filter to keep the water tank free of hard mineral deposits, available here: https://www.amazon.com/dp/B077H6KQ4Z/_encoding=UTF8?coliid=I1FSHX0YYTN79R&colid=16W4KSA0NUSMO&psc=0 The humidifier’s compact size is an added bonus for smaller spaces and it holds enough water (3.5 Liters) to operate for 12 continuous hours on the highest setting. The operation couldn’t be easier thanks to the mist control knob; just set the dial to your desired level of moisture output (300ml/h on high 70ml/h on low). Lastly, I’m impressed with the Hume Ultrasonic Cool Mist Humidifier’s industry-leading 5 year warranty that begins on the date of purchase which gives me peace of mind.

Works well but extremely difficult to clean and refill. The humidifier works well, but the design is extremely weird and difficult to clean. The tank itself is easy to clean however it's not the tank that's the problem. The base is where it gets dirty and is hard to clean due to the small areas that are hard to reach with small brushes. After a few days of using this the base started getting gunky and had a pinkish residue all over it. There was some gunk floating in the water in the base too. I cleaned it with some soap, a small toothbrush to reach tight areas and water. It wasn't as easy thing to get around the plastic parts. Days later again the base started getting dirty.The tank is also weird to fill. I would have appreciated a top opening so one can just fill a pitch with water and pour it in but you have to remove the tank and there's a knob you have to unscrew at the bottom. Because of size of the knob it's a bit hard to get a good grip on and unscrew, especially with it wet.The unit looks nice and sleek but the maintenance issues and just awkward way of refilling it makes me regret this purchase. This is my second Pure Enrichment purchase, I did not like the other purchase as well because it had an extremely obnoxious odor. Not buying this brand again.Every 3 days this amount of mold builds up and I have to fully commit 15 minutes to using a variety of cleaning brushes to fully clean it.

I have been very impressed with this humidifier thus far. I bought it, because I already own 2 dehumidifiers from made by Pure Enrichment and have been very happy with them.I bought this humidifier, because my 2 year old was getting nose bleeds on a regular basis; the doctor told us that it isn't anything to be overly concerned with, but it is being caused by the air being too dry. I put this little guy next to our bedside, and we haven't had a single middle of the night nose bleed situation since.At first, I was going to buy a humidifier, which you could set the humidity percentage on. Unfortunately, most of these give highly inaccurate humidity readings. In most cases, this is not because the sensors are bad, but rather that the sensors are in a bad position; the only ones I have been able to find have been either on the humidifier itself, or on the cord, 6 inches from the humidifier. Of course those readings are going to be higher than the rest of the room, the humidifier is literally misting the sensors.So, after coming to this conclusion, I decided to get a humidifier with a dial. Why a dial? Because the other option is one with a High or Low setting. The dial lets you fine tune the amount of humidification your humidifier is giving off much more precisely. The dial in combination with a humidity sensor is a great way to get the humidity level exactly where you want it.Also, having a dial, ensures that your humidifier will go right back to the setting you had it at if the power cuts out for any reason. The dial also makes this humidifier extremely compatible with smart outlets. That is actually my next step, get a smart outlet and schedule the humidifier to come on about an hour before bedtime.The last thing that I will talk about is the white dust problem that people often have with ultrasonic humidifiers. I can't speak for everyone out there, as everybody's tap water will depend on their water source, but I have not experienced this problem at all. At first, I was planning on buying distilled water for my humidifier to avoid any chance of the problem, but then I decided to give my tap water a chance. Pure Enrichment sells a decalcification filter separately, but it is specifically designed for this humidifier. It only claims to reduce the white dust, but in my experience so far, I have not seen any white dust what so ever.One of the main problems I have experience with buying products online, is sometimes the products don't live up to their pictures/descriptions. Several times, I have ordered something which looks great in terms of description and pictures, but when it arrives the feel is completely different.That is not the case with Pure Enrichment. I have had the opposite experience with everything I have bought from them. Their products don't feel like typical cheap flimsy junk; they feel solid and well built.

I purchased two of the these humidifiers for my grow room and it is helping a lot in maintaining the humidity and my plants love it. It is super easy to fill the humidifier with water. Hardly makes any noise. Will purchase again.
