Vornado Evap40 4-Gallon Evaporative Humidifier, Adjustable Humidistat, 3 Speed Settings, Coverage up to 1,000 sqft, 4-Gallon Output (24 Hrs), Dual Tank, Perfect for Home, Bedroom, and Large Spaces

If you want a good reliable humidifier for your space this is the one to buy. I wanted an evaporative humidifier for a number of reasons: they don't produce a residue like the ultrasonic humidifiers and cool/warm mist humidifiers can. They won't over-humidify a space like the other types can -- air will only take on as much humidity as it can hold, and evaporation slows the closer the air gets its potential saturation level. And to ensure that over-humidification doesn't happen this humidifier also features a humidistat that will switch the unit off if the humidity exceeds the level where you set it. I bought my Vornado three years ago because it's such a simple design. The top fan unit, 2 water supply jugs, the reservoir pan, and wicks. Nothing fancy at all, just like the best evaporative humidifiers I've used in the past. As far as I'm concerned the simpler the design the less chance of something breaking. At the lowest two fan speeds the unit makes hardly any noise. Even the highest fan speed I don't think it is overly loud -- I sleep fine with it running in my bedroom. My recommendations for this humidifier: Purchase a humidity meter to monitor the levels in the room so you can better dial-in the Vornado's humidistat to your preference. Use distilled water. You don't have to, the humidifier works fine with regular tap water. But in the long run distilled water will give much better and consistent results. Have at least one if not two new wick sets sitting in reserve. That way when you have to replace them you can do so right away, then order another replacement. To combat/prevent bacterial growth -- use copper. Don't waste money on additives to combat bacteria. Copper works great as an antimicrobial and keeps bacterial growth in check (that is, zero). Preferably copper mesh (usually available through garden stores), but pennies will work fine (wash them clean before using them). The problem with pennies is, over time, the copper plating will get 'used up' and then it'll be the zinc core exposed to the water (this took about a year when I first used them). Zinc is supposedly antimicrobial as well, but I didn't want to chance it, and copper-less pennies look disgusting :) . I have a six-inch strip of copper mesh in each water jug. I have never had issues with bacterial growth in the jugs nor in the reservoir nor on the wicks while using copper as an antimicrobial. Regularly clean your Vornado, including vacuuming off any accumulated dust. Be especially diligent if you use only tap water and not distilled water because limescale will accumulate in the pan and on the outer surfaces of the water jugs. I run mine 24/7, except when its humidistat setting shuts it down or while cleaning the unit. The humidistat is sort of finicky, it's not really "exact" so much as the best way to set it is if the room is too humid, turn the humidistat until the unit powers down, then wait. I realized I had to finesse the setting over a period of days, fiddling between shutting down and turning on, until I got it set just right. Once I did get it dialed in I never had to worry about it again. I recommend purchasing a humidity monitor if you really want to watch those levels. For those first three years I used tap water, which works fine. However my tap water has a high mineral content, which means the evaporative wicks harden with limescale rather quickly -- as in a matter of days. At first I was rotating wicks once a week -- I'd have one pair of wicks working, then swap it out and soak the wick in vinegar water to disperse the minerals, rinse it out, then swap it back in the following week while I de-scaled the second wick pair. Problem is, over time, the wicks deteriorate from the vinegar soak cycles. As in they start falling apart. They re-mineralize quicker the older they get. And the ability to control mineralization continues to deteriorate over time. I purchased new wicks every three months just to keep up with the deterioration. I finally decided to switch to distilled water. The humidifier uses about 2 gallons of water a day so purchasing distilled water off-the-shelf is not an option, that's too expensive. I purchased a home distiller and distill 2 gallons of water a day. I also purchased an empty 2.5 gallon jug to have 2 gallons of distilled water ready for when one of the Vornado jugs empties. I fill the Vornado jug, then distill more water into the 2.5 gallon jug. Sure, it's a little extra work, but the benefits outweigh the inconvenience. One month after the switch to distilled water the humidifier wicks have remained supple, they are not mineralizing at all. To be honest I'm not sure when I'm going to have to replace the wicks, I've been running the same filter set for a month and they're doing great. I'm sure, over time, I'll figure it out. Already I can see I'm on track to saving a lot of $$ not having to replace two pairs of wicks every three months. Home-distilled water is a lot cheaper than purchasing it off-the-shelf. It is definitely worth the added cost to purchase a small home distiller. I know my distiller will pay for itself in less than a year compared to what I was paying for replacement wicks and vinegar. I am on my second Vornado EVAP40. The first one died after three years of constant use. The power-cord wire corroded with oxidation inside the unit which increased the resistance on the AC wire until it cooked its insulation and the unit quit working. I contacted Vornado customer service and explained the situation. I sent them the pictures they requested. Vornado honored their 5-year warranty and sent me a brand-new unit. Vornado is amazing and stands by their product, I have nothing but good things to say about them, their customer service, and this humidifier. If my unit had been out of warranty I would have purchased another one anyhow because it is that good compared to all the other humidifiers I've tried over the years.

I have owned the Vornado Evap40 humidifier for about 3 years now. I initially was looking for a humidifier to try to make a dent in the super dry air of a Colorado winter and all I was finding were kinky 1 gallon or Goliath 10 gallon models and the Vornado seemed to fit my needs perfectly. It holds 4 gallons of water giving about 4 days of constant running, and the footprint isn’t massive. The Vornado does a great job of evaporating water into the air. It’s nothing fancy, it has two large filters that act as huge water wicks and a fan to pull air through them and blow the evaporated water into the air. Since it isn’t heating the water or anything it can be used for summer and winter. It makes a constant noise, like a desk fan, but I don’t find it too loud and it has three settings, the middle one you can barely hear but for a very dry winter you will want it on full. The two water tanks are pretty cleverly designed, no caps or valves. You fill them and then tip them into the machine, just read the instructions and they flow well. It can make large gurgling noises as the water glugs out so maybe for a bedroom it might annoy a very very light sleeper but I have it in my living room. The good thing is you can fill just one tank if you are feeling lazy or whatever and still get multiple days of humidification. After 3 years of non-stop 24/7 running on high my unit finally started to fail. The motor made a squeaking sound and it wasn’t working right. The humidifier comes with a 5 year warranty, I filled out one online form, sent one picture to Vornado of the unit with its cord cut to show that I had disabled the broken unit, and they shipped me a new unit that got to me in like 3 days. Literally no questions asked warranty service, no proof of purchase or anything asked, very very easy, I’d definitely buy more Vornado products just based on that.

This is working well for my living room/downstairs and loft area. It is around 500-600 sq feet. We also have high ceilings. I use a seperate humifiers for each bedroom. We heat our whole home with wood and it gets very dry inside. This is keeping our humidity around 40-42%. Last year without this humidifier we were around 29 or lower. We keep in on medium fan highest humidity level and it runs constantly. It does make some sound on medium but its easy to get used to. The high setting is very loud. I am sure it would make our humidity go lower on high, but because its in our main living area.. it would be too loud to hear the tv or just annoying to listen to! Occasionally it does make a sound as the water is filling the inside. That is easy to get used to as well and not disturbing. Very easy to clean and fill. I clean weekly per the instructions (bleach and water) and soak the wicks in 1 cup vinegar to 1 gallon of water for a half hour,rinse clean. The wicks lasts about 1 month this is with running 24/7. I just use tap water but I do not have hard water. I am happy with my purchase.

The Vornado Evap40 is a great humidifier. I went with evaporative type to avoid mist dust. With a large open floorpan, smaller humidifiers just did not work well. I purchased this about a year ago and used it last winter until spring then restarted this fall/winter. It runs 24/7 on either low or medium, aiming to keep indoor humidity about 45 percent with seperate humidistat. I replace the wicks monthly and use tap water, which is replaced daily. Cleaning is a breeze, I add a dilute vinegar solution to sit for 15 minutes or so, quick scrub then rinse. This is a great change from trying to remove scale buildup when cleaning warm mist humidifiers, which I did for years. I would estimate the humidifier uses about 3 gallons per day, although it could put out more on high speed. Not needed in my situation. Although there is some noise, it's white noise on low and medium. High, which is never used, gets noisy. If TV or music is on I don't notice the humidifier sound. I highly recommend.

I bought this Jan 2022 because it has a lot of water storage capacity. Humidifier are pretty basic by design. You have a water bowel than a filter/sponge absorbers water and a fan to suck up the moisture and mystify the air blowing through it. You would think that the most important part of the unit would be designed to operated in high humidity area and have a sealed design so moisture doesn’t get into the motor/bearings internals and seize up only after 4weeks of use. Worked fine until I drained out water and turned it off. 5days later turned the switch back on and just heard a hum coming from fan motor. Tried to spin the fan blade by hand and felt resistance like internal armor/bearings is seized. Going to see if Vornando honors their 5yr warranty

Humidificador lo estaba utilizando en mi recámara. Los resultados fueron muy malos. Terminé regalándolo.

This humidifier is a best of the worst situation. It works ok well enough compared to the rest of the garbage that's being sold these days. Despite being a dial, the humidistat inside of it is only has 2 real settings. There's a sweet spot in the dial where, if you're just below it, it stops the fan if humidity is above 35%. If you go above it, it doesn't turn off until at least 50%. Didn't wanna turn my apartment into a rain forest to test further. The wicks can get pricey to replace, even more-so if the water in your house is hard. The filters start to mold after 3 weeks even if you use distilled water and clean the unit itself weekly. Adding bacteriostatic chemicals to keep it mold free works, but then you end up inhaling toxic chemicals so you're literally picking your poison. The most annoying thing though, is that I was willing to put up with the constant wick replacement--I even bought a second unit--except they haven't had the official wicks in stock on amazon for almost a month now and they're not easy to find elsewhere or they're significantly more expensive. I would return these if I could. They shouldn't list these for sale when they cant keep the wicks in stock anywhere.

Not one to write too many Amazon reviews but here I am. So I knew within about 30 seconds of opening the box that this was absolute junk and I'd be returning it immediately, which I did. It's pressed, thin and badly made plastic and the design is something I'd expect a 9th grader to come up with in science class. Some things of note: 1) The unit ISN'T held together by any hardware. That's right - it basically comes apart when you go to fill it up. You have to line up the (laughingly thin and flimsy) plastic when putting the tanks back it. 2) The product is essentially this: a 300mm fan ($20 at any computer store) that sits atop some standing water in $5 worth of cheap plastic. 3) I filled it up, which in itself is precarious and awkward, put a dry cloth on top of the fan and let it run for 25 minutes. The cloth was still bone dry. I tried the same with my hand a dry piece of paper and nothing happened. 4) The wicks sit in the standing water, but they only get wet on the bottom. Maybe 2 inches get wet? So basically you have these cheaply made filters sitting in standing water with a very cheaply made fan trying to suck out the "moisture" that isn't even there. 5) The "temperature control" knob is basically a speed setting. It doesn't do anything. This unit has no temperature control, no sensors no automatic shut off. I honestly feel like I've been a part of a practical joke. I'm shocked at how bad this is. I meant what I said: I could make this product at home for $20.

Does not humidify air.. literally went up but 1-5% and I wouldn’t be able to tell you for sure if it was this product or not. Doesn’t work.
