EV100 Evaporative Whole Room Humidifier with SimpleTank, Easy-Fill, 1 Gallon Capacity, 2 Speeds, Electronic Humidistat, Antimicrobial Treated Wick, Perfect for Home, Bedroom, and Living Room

Very happy with this humidifier. I put in our lower level family room; works quietly and efficiently. Doesn’t leave any white dust since has a wicking filter; the dust I had problems with in the mist type of humidifier. Fills easily and may be the best humidified of its size I’ve bought over the years.

Either you will have white dust to clean up if you buy a cheap humidifier or you can buy this Vornado and change the wick filters now and then and you'll have no white dust. This is my third Vornado humidifier. I also own the EVAP40 with 2 tanks but that one alone couldn't handle the entire 1500 square foot home. So I purchased this one for the master bedroom, which measures 15 x18 feet. It works fine and the fan on low is quiet enough I don't lose any sleep. I've had this a month and no leaking at all. I'm thinking the people who complain about leaking either don't read instruction manuals or didn't test for minute cracking after unboxing. The manual says to do this. Mine was fine, so I had it set up in less than 5 minutes. The water container is easy to fill and carry. I have hard water where I live and the wick filters last me 7-8 weeks. So depending on when I set the humidifiers up for the winter season, I only need to replace them once. Sometimes I can get by with only 1 set of filters by soaking them in vinegar and then replacing them back into the humidifier. BTW, the Vornado customer service is excellent. On my original EVAP40 I bought in 2008, the fan motor started making a strange sound only 3 days before the warranty expired (a 5 year warranty). I contacted Vornado and they immediately sent a replacement no charge. All they wanted in return was the cut off cord of the old unit. The EVAP40 I'm using now is 11 years old. I also have several Vornado air circulator fans that are almost 15 years old and even now, those work as new.

I looked at reviews before buying and purchased even with the many problems reported. Almost all reported problems are not true, I'll address those below. In general, the unit works as expected, humidifying a small space effectively, but it's just too loud for my tastes. The only thing it's missing is auto-shutoff when dry if you're looking for that feature. Its lowest humidity level is 40% which is too high for freezing climates, causing excessive window condensation. Leaking: there is an entire page of the instructions dedicated to checking and testing your unit for leaks. Mine didn't leak and if yours does, it's either a cracked tray from shipping or user error (for example, the first time my spouse refilled it, they didn't seat the tank correctly into the base). Heed their warnings and test run your unit where it won't water damage the surface it's on if it leaks. Humidifying: the unit absolutely does work if you use it correctly. The reviews that claim it does nothing are clearly user error. The bottom edge of the wick must be completely touching the base because the water level is only 1/4" deep, if that. Second, it must be covering all the air intake slots--I found that I had to adjust it after it was wet (lift the white fan housing off but leave the grey housing on the base to adjust). The airflow doesn't bypass the wick and the wick doesn't flop over like two users claimed. Remember, this is an evaporative humidifier so if your ambient air already has high humidity, it's not going to work well, just like evaporative coolers don't work well in humid climates. One other thing to keep in mind if you use this on carpet, the full tank will make the unit tilt that direction so water won't adequately fill the space around the wick, therefore, you need to put something under the tank part of the base to level it out--I used a ceramic drink coaster. Blue lights: the two tiny LEDs for fan speed and humidity level go dim after 20-30 seconds and are very dim. Either other reviewers had defective units or Vornado addressed the issue in the newer iterations. These lights are not an issue unless you're looking directly into them. Cycling on/off constantly: mine works fine, cycling on/off at a reasonable interval. If yours is erratic, it's defective. Noise: this is the only issue I'd have to agree with other reviewers--it's too loud. I bought the smaller EV100 to use in our bedroom and even the low fan speed is way too loud. Our Vornado Evap40 on low is practically silent compared to the EV100 (it's not that quiet, but you get the drift). There is a definite change in pitch from high to low, but it isn't much. I've contacted Vornado support via email questioning this issue and I'll update my review if it was a defect or working as expected. If it is normal, I'll only run it during the day and shut it off at night. If you like white noise then it won't be an issue for you.

I have had an earlier version of the EV100 humidifier for well over a decade, with excellent performance. The fan motor was clearly weakening, so I ordered another one. I knew, on ordering, that the unit with the same model number no longer LOOKED the same, but the specs were identical, so I expected an equivalent device. That is not what I got. The new "equivalent" device has one evaporation pad, rather than two, cutting by half the output ability of the unit, even though the specs haven't changed! But that wasn't the worst of it. When I started using it, in tandem with the old one, I realized in a matter of hours that it was putting out less than a third of the output of the old one (with the weakened fan). Upon investigation, I found that the pad in the "new" unit I had received was actually a used pad. And not just used, but nearly entirely clogged with salts, indicating it had been used for at least two months, and was no longer absorbing water! This is downright fraud. I ordered and paid for a new unit, and got one that was clearly a used, returned unit that had never even been properly refurbished. I replaced the pad with a new one I had around for the old unit, and the output jumped by a factor of 3, making it equivalent to the impaired old unit. So by operating both of them, we are getting about the amount of humidification we used to get from the old "EV100" unit, when it was newer. I have decided not to return the new unit, since it is now working only slightly below expectations. But purchasers of this unit should be on the lookout for fraudulent replacement of new units with used ones. It is, of course, unknown to me whether the fraud occurred at Amazon or at the Vornado factory, but fraud it was. And deeply disturbing.

The product description is very accurate. It is easy to fill and easy to clean and the sound level on low is very quiet but it does make a little noise on high but that is to be expected. I started on high when I first got it but now I can run it on low all the time. Easily humidifies a very large room (combined living room and kitchen open concept about 500 square feet). I live in a region with very hard water so I use my Brita water filter and it really seems to make a difference in reducing the mineral build up on the wicks. Overall, very pleased with the quality, design, esthetics, use and noise levels! Nice to see another rare quality product on Amazon.

It's noisy as the heater sound of the house, but it works so good. All the ultra sound humidifiers need to be cleaned everyday, but this one is ok to use longer than that without cleaning. Air circulation in my room is a plus!

I have a hygrometer that I use to check the humidity of in my apartment. It can get as low as 11% humidity in my apartment. So after I threw out my old ultrasonic humidifier I decided to pick this one up. In the interim, I would boil water in the kitchen to raise the humidity to a comfortable 40% as my hygrometer would show me. When I got this humidifier, I filled it up and plugged it in, heard the fan going and set it to 60% humidiity. After several hours the humidity level did not rise 1%! OK lets give it 24 hours. After 24 hours, it used up all the water, I checked that the wick filter was damp and the fan was working but still no rise in humidity! I filled up the tank again, let it run for another 24 hours and used up all the water and still no rise in humidity! But soon as I start boiling some water, in less the a few minutes the humidity would start to rise and I can hit 30% humidity within an 1 hour so. This product does not work! If anyone else has a hygrometer and has this product, let me know if it works for you. It didn't look or sound defective as all the fan speeds were adjusting to the the level of humidity I was setting but it just wasn't doing anything. I sent it back for a full refund. Getting another ultrasonic and testing it out.

I can’t use it on my bedroom overnight because of the noise, but I use it on my home office. It does work and it’s easy to use.
