Question: From the picture it looks like the water tank is lighted.  Is this true?  I want a unit for my bedroom but I like it as dark as possible.
Document: Because these designers of electronic nowadays, and this unit especially, all think they need BLUE LED lights for the function buttons. Do these people ever see what it looks like in the dark?? May as well be daylight. I had to tape a black sock over the controls to make it usable. Otherwise may as well be sleeping with the room lights onQ
The Vornado Evap3 Whole Room Evaporative Humidifier is pretty much exactly what you want to have in a humidifier. It has a huge tank for water, it is not unbearably loud (compared to others in this price range), and it has plenty of adjustments to fit your use case.We have it in the living room, but I don't think it is a good idea to put it in the bedroom unless you like the sound of fans when you sleep (actually, I do). At the high settings, the fan noise is definitely noticeable.
The unit has a touch control and you can set the percent humidity you want... a nice feature, but not real accurate. I recommended you get a decent humidity meter and place it in a spot away from the humidifier. By trial and error you'll get things where you want them. The unit is a bit noisy on high (most are) but I was impressed with the quietness of the lower speeds. The manufacturer says it will move air throughout the room. I'm not sure I can agree with that - it didn't seem to move THAT much air, but who knows?Having tried several brand and types of room humidifiers, I would say this is probably the second-best one I've used... and for a small room like a bedroom it should suffice.
It's well built and well engineered, slightly too expensive, and smaller than it looks. Part of the good engineering is that the fan and humidity sensor are all one sealed piece, and the tank and filter holder are separate. There is no way for water to get into the motor as it does with the other units (which makes them fail after a couple years). However, since water does not ever touch any of the works, it lacks a sensor to tell when it has run dry. I had a bigger unit that would run all day for my little condo here.
Basically, humidifiers are a pain in the back to deal with and all of them have their pros and cons. I just don't want to have to buy wick filters every month and worry about making sure to get the right size and hunt for the best price.The water level in the tank is easy to determine at least, and a full tank lasts a good 24-hour period. Like with any humidifier, keep it clean. Be meticulous about this. It has to become part of your routine, as these are not maintenance-free items.
Amazingly quiet for most of the time.5)  Good, deep-set filter set up to absorb lots of moisture without drying out.Where there's room for IMPROVEMENT --1) LEDs are absolutely blinding, especially in the dark, so while you can see the lights lit up, you can't read what they're indicating.2) Gasket on the tank doesn't fit tightly and tends to fall out, or worse, INTO the tank, on almost every filling. Fishing it out of the tank, and/or just trying to get it back in place to screw the cap on is a serious design flaw.3)  True, it advertises &#34;up to 700 sq.
I think that it could probably go three nights without refilling, but I don't want to risk it running dry since there isn't an auto shutoff feature. I like that it is a closed reservoir, since I have a cat that sheds a lot, and I wouldn't want fur getting into the water tank.I have this sitting in our upstairs hallway, around which all of the bedrooms are clustered. I've been using it for about 5 weeks now, and my sinuses seem much improved. I no longer have blood in my mucus, and I haven't had a sinus headache or a sinus infection yet this winter.
The indicator lights on this model are bright blue and light up half of a large bedroom. I've had other Vornado humidifiers and they are great at humidifying but i need a dark room when I sleep. This will probably go back unless I can make Duck Tape work. Why would a manufacture design something like this for a bedroom. Disappointing! !
In my bedroom, it was pretty noticeable. The lights would be easy to cover (with a little sticker or dark tape), therefore it's not a huge deal...but Mr. Penguin had no lights whatsoever, so I never had the brightness issue before. The other con is that the unit has filters you need to replace every so often. Of course, as a higher-quality machine, you should expect higher-quality items (such as filters)...your plain and simple humidifier would have nothing of the sort.Overall, a great machine.
On low, in a 250 square foot bedroom it holds the humidity 10% above ambient. No complaints there. It's also easy to fill, and the whole unit is very easy to disassemble for cleaning or maintenance (wick replacements, etc.). And of course, as I mentioned, it looks very nice.Lastly, I can't speak to the integrated humidity sensor/controller. I imagine it works fine, but I really haven't used it as I always just leave it running at the low setting.Overall, unless you're willing to pay a premium for nice aesthetics, I think you can find slightly better quality and value elsewhere.
Answer: The water tank does not light up. But there are 2 tiny blue lights on the display indicating speed and humidity level and those are quite bright. Mine is in the living room and it definitely acts as a night light.
