Customer Reviews

All in all, not a very good design and obviously poor construction.
Jamie Jorgensen
You can also limit the flow to what will evaporate before it lands on the floor, so that you shouldn't get a wet spot on the floor nearby if you set it right.

I tried looking it up online at the Holmes website and they don't even list it as a product.

I returned this item to the store after just a few uses. It worked for the first few nights but then after that it stopped putting out steam. After reading the troubleshooting portion of the manual, it warned that the humidifier must not be moved when humidifier is working because it sets off some little whatnot inside. The "remedy" is to simply unplug it & pour out all the water from the machine & then set it up again. This is supposed to reset that whatnot back to were it's supposed to be so that the humidifier can start putting out steam again. Well I did this and made sure to place it exactly where I wanted it on the table before turning it on; I didn't dare move (or even touch) the darn thing. So when I turned it on, there appeared to be steam coming out so I assumed there would be no more problems & went to sleep. In the morning I saw that the tank was still filled up to the top with water so it obviously must have stopped putting out steam soon after I turned on the machine. I was VERY disappointed. What a piece of junk if you can't even move this thing even slightly without displacing some thing inside that will make it stop working. I haven't been able to get a new one yet as now I know better to do more research before choosing a humidifier.

For a child's room, you need a small ultrasonic cool mist humidifier. (Warm mist is too dangerous, and evaporative cool mist models have noisy fans.) It's hard to find a good option - most people want the Chevy Suburban of humidifiers, it seems, with the biggest tank and the most humidification possible, so that's all that seems to be available.

But in a small room those bigger humidifiers not only take up a lot of room, they put out much more humidity than the room needs. A too dry room is bad for health, but so is a too damp room. In fact, even a smallish humidifier can be too much if it has only one or two settings for the flow of humidity, as many do. You end up having to guess how much to fill it up so that it runs out of water before stuff starts to grow on the walls.

The Holmes HM500 is small and has a variable humidity setting, so after a little testing you can determine what setting will keep the room at a healthy humidity. You can also limit the flow to what will evaporate before it lands on the floor, so that you shouldn't get a wet spot on the floor nearby if you set it right.

It will put out a pretty impressive stream of fog on the maximum setting, but more than you can probably expect will evaporate before it reaches the ground unless the unit is up high. (It might be great for special effects or a terrarium or vapor therapy, or something, though.)

A small fan pushes the mist out the nozzle, so this model isn't silent but it is quiet - especially it's several feet away. Many will find the noise soothing, some won't like it. The fan keeps running even when the tank is out of water, to dry out the base they say, so FYI - don't forget to turn it off if you're planning to be out for a while.

We got this today and are returning it tomorrow.

As advertised, it put out a substantial volume of cool mist, like other ultrasonic humidifiers. Unlike others that we have owned, however, it put the mist out at such a low velocity that a substantial amount of the mist sank (instead of rising) and puddled on the floor next to it.

We could (and did) put a towel down; but there's no reason to settle for a poorly designed product when other, similar devices work well.

I bought this from Target because I just needed a small humidifier for next to my bed at night. The very first time I used it, it leaked water all over the place. I checked the troubleshooting section of the user's guide and it just said that it probably was the cap on the water tank was not closed tightly enough. I tightened the cap and fixed a little floaty thing that had come loose. The same thing happened again. In fact the only time that it did not leak water all over the place was when I barely filled the tank just enough to allow the base to have the little amount of water it needed to make mist. When I did that it worked great for about 10 minutes and then no matter what I did, it would not propel the mist out of the spout on the tank. If I took the tank off the base while it was running I could see that the base was making mist it just wasn't going up to the spout for some reason. I tried looking it up online at the Holmes website and they don't even list it as a product. What a waste of money. I was never able to use this product.

If you want your carpet to be soaking wet every morning, this is the unit for you! It seems to have a design flaw that allows too much water to run from the tank down into the lower humidifier section. The result is 1) no vapor, and 2) water all over the place. (I suppose the water in the carpet WILL eventually evaporate, and that IS a sort of humidification...)

Read how many of the other reviews here talk about leakage - and decide how many days you want to waste trying to get this thing to not leak. I suspect you've got better ways to spend your time!
