Holmes Ultrasonic Cylinder Humidifier HM411-BTU-FCA

This humidifier worked great for a while. Like everyone else, the high setting only lasts a handful of hours, and the light is very bright. I went to turn it on tonight, and it became making a loud humming/grinding noise! Very disappointing, since it’s a brand I trust and re ignore for quality!

I bought this last week and I am very disappointed. It says on the box that it can run up to 15 hours - this is not true. On the high setting it runs for at max. 3 hours, and on the low setting you can maybe get it to run for 8 hours. The low setting barely lets out any mist. This is a waste of money, I regret not reading the reviews before buying.

I regret not reading the reviews first unfortunately I bought this one and it has zero power can’t c any mist coming out unlike the different one I got for my sons room.

It has a great output quality, but after about 1 year, it now makes this awful humming sound and is random when it does it.

Am giving 2 stars instead of 1 because the output on this machine is actually great, it is the fact that it doesn't last more than a few hours on the "high" setting that is unfortunate. I bought for my daughter's room, but won't even last until we go to bed a few hours after she does.

I was surprised at how powerful this unit is. It works great for individual care. I also like it’s safety features.

I purchased this item two days ago. Chose this model because (a) No filter and (b) Purported to be quiet (and it IS quiet so Holmes got that right, so far). First night ran it ALL night on LOW setting. Second night tried the HIGH setting and even though I turned it on at 11 pm, by time I awoke at 5 am the unit had turned off. Thankfully it does have that capability. However, the capability it SHOULD have is that it can run on HIGH ALL night - that's 8 hours. It doesn't do that, so back it goes. Nice try Holmes - usually like your products but this time you failed miserably. Maybe change the "up to 15 hours" notation to "will run 8 hours on LOW, and only 4 hours on HIGH" - never mind the "up to" that never means anything.

I really should have read the reviews before purchasing. I was in the store unfortunately and needed one asap, and the box information sounded great. It only worked well for about a week, although from the beginning I was refilling the small tank way too often, then it started getting loud. And just from an aesthetic point of view, the power light was very bright, much brighter than it needed to be, especially for someone like me who likes to sleep in pitch darkness. I ended up covering the power button with duct tape, just over the light, and it took 4 strips to even dim it, and you could still see it through the tape. But, eventually spring came and we didn't need the humidifier any longer. so I let it dry out completely and then put it in storage. Now we are at present day. I was so happy to remember that I had a humidifier because the air got so dry so quickly, so I set it up on my dresser. Not 2 minutes later I heard a lot of dripping, only to find out that the entire tank had emptied onto my dresser and carpet but the humidifier was still trying to run! So I hit the power button, but it wouldn't shut off! I had to frantically pull my dresser out to try and reach the plug over my soaked dresser and wall (which was super nerve wracking, I didn't like the fact that it dumped water down right next to my outlet!). So I promptly took the humidifier outside and threw it in the trash. Please do not purchase this because it is a safety hazard, and from reading all the other reviews that say it did the same thing, I have to assume the company knows about this issue. Do not put this in a room with your children, let alone in the house with your children. I hope they at least fixed that issue before manufacturing more.
