Elechomes Humidifiers for Bedroom (6L), Ultra-Quiet Warm and Cool Mist Humidifiers for Home, Baby and Plants, Humidity Sensor, Sleep Mode, Timer, UC5501, White

Overall I'm very pleased with the humidifier, it works well and I really like the auto shut off feature/sensor that will hold the humidity constant throughout the night (or day). I had a small issue with mine where, I believe, the sensor wasn't working properly and Elechomes support was a pleasure to deal with and sent me a new unit. No problems with this one. Thanks Elechomes .

First of all, this humidifier does what it's supposed to do - it monitors the humidity in a room and gets going once the humidity drops below a set percentage. The tank is big and easy to fill, and it plops right back into the machine. The filter (sold separately) is also super easy to install. I love that it has two nozzles on top of each other that can point in different directions and cover a wider area. The reason I subtracted a star is the noises it's making. Not the nozzles or the steam - when it comes on, there is a noise almost like a faint growl (I suspected cat shenanigans before I realized it is the humidifier). After installing the filter, from time to time there is a "belching" sound as a bubble of air travels through it. Other than that, I'm very happy with my purchase and hope it will last me a long time! Edit: I added a star to this review because of the fantastic customer service! They were super quick in their responses and very generous, I seriously could not be happier. Thank you, Elechome!

TL;DR: Good humidifier, some quirks, scale from hard water (even with tank filter) is a pain in the butt to clean. After having used this humidifier almost every day for the past month, I can say that overall I'm happy with it's performance and functionality. It has a few quirks that I don't love (no way to turn off beeps when adjusting settings, warm mist doesn't work in sleep mode, difficult to clean scale off heating plate, warm mist settings are a bit finicky). I would love to get an update from the manufacturer on if there's any recommendation for cleaning hardened scale residue aside from just dish soap and sponge/dish brush. I've had to resort to using my nails to get the really stuck on parts. Overall I recommend it, especially at this price point I think it is best on the market at the moment. However, if you have hard water, even if you're using the tank filter attachment, the scale makes this a pain in the ass to clean.

This is my second humidifier I received - the first one had (what I believe to be) an electrical issue that kept shorting out. The company was so kind and understanding and sent me a replacement. Look at the mist that comes out of this!! I could not be happier. I just received the replacement so I haven’t been using it that long yet, but I can already tell the air is less dry. I have asthma, and this has helped my breathing so much already. Also, I think my plants are going to love the boost of humidity too! I am so incredibly thankful they sent me a replacement - this humidifier is beyond amazing!

I really wanted to like this unit. It had features that I wanted and got good reviews. Unfortunately, my experience with this humidifier was not a positive one. Maybe I got a factory reject. The humidifier completely stopped working 2 days after the return window closed. Now I have to start the search all over. I am hoping that the manufacturer sees this and offers to replace it as a good will gesture. I will report back if this happens. Here are other indications that this unit was destined to fail prematurely. The unit worked well for the 1st 2 days. I had it set to produce high quantity, cool mist until 50% RH (relative humidity) was reached, then shut off until the room's ambient RH fell to 45% or below, at which point, the unit should have turned back on. No sleep timer or any other controls were engaged. My experience as a field inspector has shown me many times over that the built-in humidistats on these types of units are of low quality and unreliable. Therefore, I put 2 calibrated stand alone digital hygrometers in the room. As mentioned, the humidifier performed as advertised for the 1st 2 days. Problems began on day 3. The humidistat on the unit start reading higher than the two separate digital hygrometers. A couple of percentage points higher would have been acceptable, but it soon became 20% points higher. This is completely unacceptable. I had to keep turning up my desired set point on the humidifier to trick it into staying on in order to achieve and maintain my desired endpoint of 45-49% RH. This is critical to protect valuable stringed instruments stored in this small 9x10 ft bedroom. This soon became an impossible task. I would check everything before leaving for work in the morning. By the time I returned home, the room was down to 30-32% RH, and after about 2 weeks, the %RH was in the 20's! Yikes. The water tank was full, so I believe the sensor thought that it didn't need to turn on. At this point, I decide to completely forgo using a preset RH. Instead, I set it to the lowest cool mist output setting & let it run continuously. This didn't work either. Towards the end, the humidistat on the unit thought it was over 90% in the room. My 2 hygrometers were reading % RH in the 70's. I cleaned the unit one last time. Afterwards, the unit has never been able to be turned on. The on-board buttons do not engage. The remote control does not work either. Now the unit is completely unusable & I cannot return it. Lastly, I found that the base is not easily cleanable, btw. There are nooks & crannies that required me to break out my set of extremely tiny brushes to mechanically scrub those channels. Swishing a little vinegar is only step 1. You must use a Q-tip, small brush, paper towel- anything to mechanically remove residue, dirt, microbes, etc. from surfaces. Maybe that's my hospital training, but it is absolutely true. This is another thing that the manufacturer needs to re-evaluate. Make all of those tiny channels wider so that normal people can actually get in there with a Q-tip. I should also note that I purchased the recommended separate water filter plus the humidifier tank cleaner cartridge that acts as an antimicrobial water treatment by continually releasing aluminum oxide and silver into the water. Both items were used every time. All in all, this humidifier looked good on paper but was a huge disappointment and ultimately, a waste of my time and money. Sadly, I cannot recommend this product.

Overall I am pleased with this unit. It is very quiet. I haven't cleaned it yet and I haven't used the sleep mode yet, so I did not rate these two topics. I do need to be critical of one thing, however. You will receive this humidifier without a filter and when you read the manual, Elechomes RECOMMENDS a filter for best use. In the overall write up for the item it doesn't tell you that the filter is not included. I was using purified water but as frequently as I'm filling it up, I'm not going to spend the money to buy about 15 gallons of purified water every week. I just reluctantly bought a filter to use tap water. I think that if a filter is recommended by the seller, then it should be included with the item. Filters will cost you an additional $16-$20. Just be aware.

I scoured the internet for hours looking through hundreds of humidifiers before deciding to purchase this product, and I have to say that I am very dissapointed. The unit is easy to use, the materials are high quality, and the output looks impressive, but it doesn't perform as advertised. I have an 850 square foot apartment, and even after running this thing at maximum output for several days straight, I wasn't able to raise the humidity by a noticeable amount. Now you might be thinking "the page says up to 750 square feet of coverage, your space is too big" and you'd be right, but I've tested it in several different scenarios with rooms closed off and sealed, with the same results. In a 560 ft2 space, the best result I've seen was an increase from 27% to 33% relative humidity at a temperature of 70°F over more than a day of continuous operation on maximum output. In a 14' x 16' (224 ft2) room its more than sufficient, but from everything I've gathered from several tests on larger spaces, I believe that the coverage area for this unit is vastly overstated. I've contacted Amazon customer support but they just directed me to the manufacturer. There is still a chance that my unit is defective, but the output stream looks like what is shown in videos and pictures I've seen, so I'll be returning this if the manufacturer is not able to provide a unit with the advertised capacity.

After being born and raised in a highly humid environment, my family and dogs struggled with the impacts of a much, much dryer climate. We have an open floorplan house and was able to place this humidifier in a spot that takes care of both the upstairs and downstairs. Once we got the humidity above a certain point, both my husband and dog felt instant relief. It's incredibly easy to fill. It's quiet and sounds a bit like a babbling brook if anything. I can barely hear it when it does make noise. The sleep mode is simple to turn on and off. After using it for 5 days, I would highly recommend. Will update after more time with the product if I encounter any issues.
