## Description

Product Description The Evap40 Whole Room Evaporative Vortex Humidifier creates a comfortable, perfectly humidified living space quickly and quietly. Vornado's deep pitch blades pull large volumes of harsh, dry air through two humidifying filters, and then, using Vornado's signature Vortex Action, circulates the humidified air throughout the room, providing complete and uniform humidification in spaces up to 1,000 sq. ft. The Evap40 delivers automatic humidity control with a built-in humidistat. An easy-to-use control panel allows you to choose your desired humidity level and fan speed (low, medium, or high). Its extra-large 4 gallon capacity provides up to a 4 gallon water output when operated continuously on high, allowing for long, uninterrupted operation and fewer refills. Backed by Vornado's 5 year limited warranty. Do not use gasoline, thinners, solvents or other chemicals for cleaning. Humidifier components are not dishwasher safe. Do not submerge humidifier tops in water. Power: 43 Watts.

Improper use or shipping the product outside the U.S. will void all warranties.

Review: If you want a good reliable humidifier this is the one to buy - 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.
Review: The Vornado Evap40 works great and Vornado has an excellent warranty - 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.

### ⭐⭐⭐⭐ Great humidifier
*by J***C on December 19, 2025*

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.
