Question: Is this cool or warm mist?
Document: Not knowing whether a cool or warm mist humidifier is the way to go, i decided to go with this model because of the positive reviews. While i do like the control features: humidity on/off sensor, auto fan, humidity percentage - it's just too dang loud for a single room.
I would not recommend buying this product at this time.I bought a "Honeywell Germ Free Cool Mist Humidifier" instead and have been very satisfied with it. It is of similar size, very quiet, and cheaper.
Other evaporator humidifiers are usually very loud. This one isn't quiet but its not the loudest either. Its more like a constant hum. It can get annoying in the bedroom, but should be unnoticeable anywhere else. It works in a large space and allows you to choose the humidity.I switch over from the cool mist humidifiers because those would only work in a small space and they would leave a sticky white film/dust everyone if you live in an area with hard water.
My Crane vaporizer creates an extra-humid environment close to my bed, and allows the cool mist to be directed at my sleeping area. ***  SETUP. When you power the VORNADO EVAP3 HUMIDIFIER on, you use buttons to set the fan speed (high, low, auto) and the humidity level (35%, 40%, 45%, 50%, 55%, 60%, Continuous). The fan will start only if the built-in Humidistat detects a room humidity level that is lower than your chosen setting.
The VORNADO EVAP3 WHOLE ROOM HUMIDIFIER will automatically  maintain a whole room at the desired humidity level (35% to 60%). It can also be run continuously for maximum humidity (although 60% or more humidity can result in undesirable condensation/frost on your room's windows). The output is cool air that circulates and makes the entire room feel a little cooler (just like any electric fan). When the humidifier is operating at a high humidity setting in winter, I need to use my electric blanket (low setting) to counter the cooling effect.Because it's a whole-room humidifier, this product is NOT necessarily a substitute for a small cool-air bedside vaporizer (e.g.,Crane Ultrasonic Cool Mist Humidifier).
We've purchased a lot of humidifiers over the years. Things likeCrane Adorable Ultrasonic Cool Mist Humidifier with 2.1 Gallon Output per Day - Penguinwhich looks cute and worked well, but barely lasted a year. We've also purchased things like theOptimus U-31005 2.0 Gallon Cool Mist Ultrasonic Humidifierwhich worked too well as we'd wake up to a foggy room and the piece grew algae amazingly quickly and was extremely hard to clean. So now my family is on the Vornado Evap 3 Whole Room Humidifier. It works decently, as you can feel the room's humidity increasing without seeing copious amounts of mist, but that's about the only positive thing I can say about it.For one thing, the machine is the loudest humidifier I've ever had.
Although more expensive, I highly recommend the Ultrasonic Vornado. With that unit. more water gets pushed into the environment (I would estimate about double the water) and you can actually see the mist entering your room. This is invisible and works at a much lower rate. If you need a high-output humidifer, look elsewhere. Build quality is also lower than the Ultrasonic.
The container does not fit under a bathroom tap, and it is not flat, so it is not easily balanced while filling. Although the container does need to be turned upside down to be replaced it doesn't spill all over the place.-The fan works well. Even on low the mist is spread well throughout a large room, rather than just concentrating in one area.-The mist does evaporate, meaning humidity is increased, but moisture doesn't settle on furniture, walls, or the floor.-The controls are simple and easy to use.
First bit of information: Evaporative humidifiers don't produce mist! If you're looking for steam or mist, this won't give you any.It does, however, work quite well. Our son sleeps with fans all the time, so this works out great for him. If your baby can't handle sleeping with noise, though, the Vornado Evap3 isn't particularly quiet.Remember that whatever water you put in there will go into your lungs. You'll either want filters or high quality water. We use reverse osmosis water in the humidifier so we don't have to use filters.
This humidifier works good, a little noisy in living room but not bad. Got it from costco not here. Filters need to be Changed regularly. It's not made in usa but what is anymore. Really easy to cleanI was debating on doing a whole house humidifier for a while, after I talked to a HVAC business owner I decided against installing one. He explained to me that the humidifiers that install on your furnace are nothing but germ traps and that he would never put one on his own house. He went on to say that if you do have to go that route to install a on demand mist type.
Answer: Cool mist only but doesn't send out a dust like some warm air ones do...such as an ultra-sonic humidifier.
