## 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.

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: Life saver, worked when no other humidifier helped. Absolutely worth it - This vornado humidifier is truly a life saver. I had a levoit tower $150 humidifier that didn't make a dent in my extremely dry room. We have old radiator heating and a lot of exposed pipes and it gets extremely dry 20% humidity dry. For some reason the dryness was worse this year and I was struggling to breathe, wheezing, I couldn't get my Levoit humidifier to go above 30%-35% even running 24/7 on the highest setting. I decided to try an evaporative humidifier and after a few days of research settled on this one because of the fan and I thought it would reach a better range with my tall ceilings. Within a few hours of using it got my humidity up by 25%. I finally was reaching comfortable levels of humidity and could breathe like normal. I use distilled water as I have a water distilled machine, totally worth it, I haven't had to change the filters yet or dealt with any grossness. I fill 2 gallons at a time usually, and if I want to use less for a shorter amount of time I usually just fill one side instead of both. There is a learning curve to get the containers on without spilling. Instinctively we want to go slow especially because it's full of water, but you have to just lay the containers down on the grove and quickly put them in in one fast movement. Don't need to use force just go quick otherwise water will spill. Once I realized that I haven't spilled it at all or had any leaking issues. I keep it running once the water is done to dry out and dry the wicks. It does make a "glug glug" noise every few hours depending on how high you're running it but I don't think it's loud or bothersome, I barely noticed it at first. The fan sounds like a fan, not sure why it seems people expect it to be quiet, any fan on max is going to make some noise, it's no louder than any other fan I have really. It's not quiet but I don't think it's unreasonably loud, could take some getting used to if you're sensitive to these types of sounds. There was a smell initially, it was off-putting but I was prepared based on reviews. It was the wicks not the decide itself so think it's unavoidable with any wicks. It took a few days to go away but eventually did completely. I'm impressed and surprised by the simplicity of the whole thing really. I'm used to the Levoits that's a bunch of pieces and is a pain to clean, this thing is really simple but functions great. I'm so glad I made the switch. No hate on the Levoit it wasn't the only humidifier I've had but was the fanciest most expensive one and I definitely had higher hopes and expectations for it. Thankfully, this one succeeded where the other failed Photos are 1) the humidity level in my room after this current humidifier was off for a few hours when I wasn't home 2) humidity level within 2 hours of turning on the vornado humidifier 3) my Levoit humidifier, and even when it was running for hours on high I couldn't get above 34% humidity at most

### ⭐⭐⭐⭐ Great Humidifier For Large Rooms, But....
*by J***S on March 28, 2024*

Before I review this product I feel it is important to differentiate the three different types of humidifier. Important note, all 3 types will have the occasional "glug glug glug" sound as water empties from the tank into the humidifier unit. - First, the Cool Mist. These use high-frequency sound vibrations to create a very fine water mist. The mist these emit is cool, and they are very quiet. They have no fan so slight hum is typically all you hear. They can end up leaving moisture on their surroundings, the cool mist does not just disappear up into the room but often will partially settle back down onto the table, floor, etc... It won't be dripping wet, but you need to be aware of this potential moisture issue. You'll need a source of air circulation to evenly humidify an entire room with this type. These require no filters or other consumables, use of mineral absorbing gadgets in the water is often mentioned but not required. They can be a real pain to clean depending on how many corners, nooks, and crannies were designed into the unit. Filling the unit with vinegar water for a soak will simplify things. The main drawback to these is the ultra fine white dust that gets on everything, everywhere. All the minerals in your water will end up in the air, and then in your closets, drawers, and cabinets, and on every surface everywhere. - Second, the Warm Mist. These use a mini hot plate to boil the water and emit a cloud of steam. It will be warm to hot if you stick your hand in it. Not only do they humidify but they can also cause minimal increases in room temperature. They also have no fan and run fairly quiet, but a little noisier than the ultrasonic Cool Mist type. Again, you'll need a source of air circulation to evenly humidify an entire room with this type. These also require no filters, but many will need small, inexpensive pads to absorb the minerals in the water which helps prevent them from solidifying into a layer over the heating plate. These units can be ridiculously difficult to clean depending on the design, and care must be taken to not scratch up the heat plate. - Third, the Evaporative humidifier. These have large wicks which soak up water, and a fan pulls air through the wicks, evaporating some of the water, then sends the humidified air out into the room, These emit no mist or cloud of steam. Given the fact that they have a fan they are a little noisier than the other two types, but they will humidify the entire room a lot better and quicker than the other 2 types because of the air circulation. Typically these are easy to clean if done regularly although this depends in large part on what's in your water. Also, this type uses wicks which will have to be replaced at regular intervals determined by the mineral content of your water. They go for around $10-$15, so be aware there are continuing costs if you use this type of humidifier. This unit is an Evaporative type, and it works quite well. Here in the Pennsylvania winter it easily keeps a large bedroom with attached sitting room at 50% humidity on the medium fan setting with the humidity control set between half and two thirds. It will run for a 2-3 days (sometimes more) without needing a refill due to the large tanks, which is phenomenal compared to other units I've tried. Refilling is super easy since there are no caps or valves. Fan noise is minimal on medium setting, almost imperceptible on the low setting unless you are in a very, very quiet setting or have it placed unnecessarily close to your bed. The occasional "glug glug glug" of the tank refilling the chamber is louder than the fan unless you're using the high fan setting. As of the date of this review it has been up and running for 7 weeks and I have not yet needed to replace the wicks. I have flipped them once, that's it. Overall I am very happy with how this unit performs, but there are a couple negatives. First, the humidity control is wildly inaccurate on mine. One day it will be shutting off when the room is at 42% humidity, a couple days later it will still be running when the room is at 60% humidity. That's a big difference, going from easy breathing to rain forest without touching the settings. Keep a separate inexpensive humidity meter in the room to accurately gauge the humidity and make adjustments to the settings as necessary. Second negative, the price. This thing is outrageously expensive given the complete lack of technology inside it. There's a 4 position on/off/fan speed rotary switch, a dial for the inaccurate humidity setting, and a fan. No touch screen controls, in fact no screen of any kind. No fancy digital controls, no bells or whistles, we're talking 1970s tech if not earlier so the comparatively high price is really unjustified. Also, the product page claims in two different places that this unit "senses how much humidity and circulation is needed to maintain your ideal environment and makes adjustments automatically." I have yet to hear this thing vary the fan speed, so I'd have to say it is not sensing and/or responding to the need for more air circulation, or less for that matter. I've no idea what adjustments it is supposed to be making, and the included manual makes no mention of this ability. It turns on, or off, when the supposedly appropriate humidity level has been reached. That's it. I'd have to rate this claim as false. Overall it's a highly effective unit, fairly quiet, easy to fill, easy to clean, with minimal costs for consumables. I'd recommend it.
