Question: Is the humidifier supposed to have water in the base part?
Document: Oh my gosh - it was a NIGHTMARE. First of all, you use TWO FILTERS at a time - and they come one or three in a box. What's with that?!?!? The filter doesn't fit nicely in any obvious place. You have to take the base apart - completely - and you WILL have water everywhere so do it in a tub or sink. I needed a wetvac by the time I was done.
Both of these design improvements make it much easier to move the unit when there is water in the tank/base.On the negative side, I agree with a lot of users here that filling up the tank is awkward due to the lack of a flat top to hold the tank up.Performance is decent and I've verified with an external hygrometer that the humidistat is accurate.
?Really, who's going to do that?And, using an antibacterial solution and soap?Well, the unit comes apart easily and cleaning it was no problem, just a little mess if the tank still has water in it. You need to work on it in the shower or kitchen sink. The bad part are the filter pads. They are a paper like material that I have only seen in baby diapers, with a nylon net around them.
In the past, I have been very disappointed with humidifiers. Either they leak or don't seem to do much of anything. However, this Holmes U Tower humidifier is sleek in design and has a few nice features such as:- The two filters are easily accessible at the base of the unit.- The tank is easy to handle, fill, and not too heavy to carry.
Ive gotten 2 of these already they are very sensitive you need to maintain the filter often, i run a printing company with DTG printers so the humidity needs to be on point this humidifier works great silent than like a month later it starts to get louder?! im pleased with the humidity part but noise and maintenance is a pain in the ass
This humidifier was returned after 2 nights. The fan was obviously not installed correctly as it made a terribly annoying noise that was so loud it needed to be shut off. Also, the reading on the digital display indicated that the humidifier, while set on high, only increased the level from 22 to 30% humidity in the house. I think the most annoying part was trying to fill up the tank and having it slide off the edge of the bath to have it spill all over.
The big draw of this model is that you are supposed to be able to set the humidity level to a certain point and the humidifier will run as necessary to keep it there. But what ends up happening is that it simply cycles on and off (sometimes for just a second or two) in order to keep the humidity level constant. I thought maybe just my unit was defective until I saw other people had identified the same problem. The only conclusion is that this is a design flaw.
Obviously, a major part of the fault lies with the manufacturer. Be advised to immediately test such products and, if any problems occur, formally request an immediate remedy and keep records. When I told my son about this experience he said that he thought the company making the product had changed.
Just bought this thing...filled it up once - worked great - had to fill it up again and it's so awkward to hold - it slipped and cracked completely. Called to order a replacement tank and they don't even have any!!!! So, basically I threw all my money out the window! Very upset. They said to call back in two weeks to try to order the part?
The only big worry is the fan. after the first week it started to be louder exactly the same way explained by another reviewer, it sounded like a small engine starting up(although is a motor and not an engine lol). The weird part is that today its stopped doing that. The fan still is a bit loud but not enough to stop me from sleeping although I have not tried that since its current location is at the living room.
Answer: Yes. The water flows from the reservoir into the base where it's wicked up by two evaporative pads (inside the housing). The air flowing over these pads becomes humidified and exits the top of the unit.
