What the Vornado UH200 Ultrasonic Humidifier is
The Vornado UH200 Ultrasonic Humidifier is a whole-room humidifier meant to do more than take the edge off dry air next to your bed. Vornado positions it for spaces up to 900 square feet, and the design focus is clear: move moisture around a bigger area, not just create a damp corner near the unit.
It’s an ultrasonic humidifier that can run warm mist or cool mist. That’s useful if you want cool mist most of the time but like the idea of warm mist in winter, or if you’re trying to balance comfort in a room that already runs chilly.
Unlike basic humidifiers that are basically “pick a speed and hope,” the UH200 includes an electronic humidistat and an Auto mode. In plain terms, it can aim for a target humidity range and adjust itself, which helps you avoid both dry air and the clammy windows and damp surfaces you can get when a humidifier runs too hard.
Why it stands out
The big reason to pay for the Vornado UH200 Ultrasonic Humidifier is output plus control. Vornado lists a 1.75-gallon tank and up to 4 gallons per day of moisture output. That combination is what makes a humidifier feel “whole room” instead of “personal.” A large tank by itself is not the whole story, but pairing it with a high daily output is a better sign that the machine can actually raise humidity in a larger, drier space.
The built-in humidistat is the other standout feature. Vornado says you can set it for 40 to 60% humidity or run continuous output. That matters because large-room humidifiers can overshoot if you just leave them blasting. Having a machine that can cycle around a target is a real quality of life upgrade, especially if it’s running all day in a living room or overnight in a big bedroom.
Convenience features are unusually strong here for a non-smart humidifier. You get touch-sensitive controls with LED indicators and an RF remote that senses humidity. RF is nice because it typically does not require line of sight like an old-school IR remote. If the humidifier is across the room, you can still make adjustments without walking over to it.
Finally, Vornado leans on its circulation approach to distribute humidity throughout the room and reduce the chance of water pooling on the floor. The practical takeaway is that it’s built to push moisture outward, not just dump mist straight up in one spot.
What it is like to own
Daily use is straightforward: fill the tank, choose warm or cool mist, and either pick a fan setting or let Auto handle it. The touch controls and LED indicators are the kind of interface most people can figure out without reading a manual, and the remote is genuinely helpful in a larger room where the unit might live on a side table or in a corner.
The tank size is a big part of the ownership experience. At 1.75 gallons, you are not refilling it like a tiny bedside unit, and Vornado’s stated 4 gallons per day output tells you it can also run hard when conditions demand it. In a very dry spell, that higher output can be the difference between “humidity barely moves” and “the room actually feels better.”
Cleaning and water habits still matter. This is an ultrasonic humidifier, so the water you put in it can affect what ends up around it. If your tap water is mineral-heavy, you may want to use distilled water or plan on using a mineral cartridge (Vornado lists a replacement mineral cartridge, model MD1-0018). Either way, you should expect routine emptying, rinsing, and descaling to be part of owning it, because standing water is standing water.
What to know before you buy
First, treat the “up to 900 sq ft” coverage as a best-case claim, not a promise for every home. Room layout, ceiling height, how dry your climate is, and how much outside air leaks in all change what a humidifier can do. The more useful specs to anchor on are the 4 gallons per day output and the fact that it has a humidistat to keep things from running away.
Second, warm mist capability usually means higher power draw than cool mist only operation. Vornado lists 176.7/170 watts, which is not outrageous, but it is a real appliance, not a tiny USB gadget. If you plan to run warm mist for long stretches, it’s worth knowing it will use more electricity than a basic evaporative unit that relies on a fan and wick.
Third, size and weight are part of the deal. The UH200 is about 16.36 x 8.53 x 18.41 inches and weighs 9.32 pounds. That’s fine for a living room or a dedicated spot in a bedroom, but it’s not the one you’ll happily move between rooms every day.
The specs that matter
This is aimed at living rooms, open-plan spaces, and big bedrooms. In real homes, output and layout matter more than the number, but it’s clearly not a tiny bedside unit.
A larger tank usually means longer stretches between refills, which is what you want if the humidifier is running all day or overnight in a larger room.
Output is what actually raises humidity. Higher output helps in very dry conditions or bigger spaces where small humidifiers can’t move the needle.
You can choose cool mist for everyday use or warm mist when you want that warmer-feeling humidity in winter.
A humidistat helps prevent overhumidifying, which can lead to condensation and a generally clammy room. It also means less babysitting.
Auto mode is the “set it and forget it” option. Touch controls are faster than fiddly knobs when you just want to make a quick change.
In a large room, remote control is not a gimmick. It means you’ll actually adjust settings instead of leaving it on one mode for weeks.
Humidifiers live a hard life with water and mineral buildup. A longer guarantee can matter if you’re paying for a larger, more permanent unit.
Who this product fits
You want one humidifier for a big living room
The Vornado UH200 Ultrasonic Humidifier is built for broader coverage, with a stated 4 gallons per day output and an Auto mode that can maintain a target humidity range instead of blasting nonstop.
Your bedroom is large and you wake up dry
A 1.75-gallon tank is sized for longer overnight runs, and the humidistat gives you a way to aim for a comfortable 40 to 60% range rather than guessing and risking a damp room.
You want warm mist sometimes, not always
Warm or cool mist lets you switch based on season and comfort. You can run cool mist most days and use warm mist when the air feels extra harsh in winter.
You hate getting up to change settings
The RF humidity-sensing remote is made for across-the-room control, which is exactly when a humidifier is doing whole-room duty instead of sitting on your nightstand.

Vornado UH200 Ultrasonic Humidifier FAQ
Is the Vornado UH200 Ultrasonic Humidifier good for large rooms?
It’s designed for them. Vornado rates it for whole-room humidification up to 900 square feet and lists up to 4 gallons per day of output, which is the kind of spec that matters when you’re trying to humidify a bigger space.
Does the Vornado UH200 have a humidistat?
Yes. It has an electronic humidistat with target settings in the 40 to 60% range, plus a continuous output option. That’s useful for keeping humidity steadier and avoiding overhumidifying.
Is the Vornado UH200 warm mist or cool mist?
Both. It’s an ultrasonic humidifier with warm or cool mist humidification, so you can choose the mode that fits your comfort and season.
Do I need distilled water with the Vornado UH200?
It’s an ultrasonic humidifier, so water quality matters more than with many evaporative models. If your tap water is mineral-heavy, distilled water can help reduce mineral residue, and Vornado also lists a replacement mineral cartridge (MD1-0018).
What kind of controls does the Vornado UH200 use?
It uses touch-sensitive controls with LED indicators, and it includes an RF humidity-sensing remote. You also get fan settings including High, Low, and Auto.
Should you buy the Vornado UH200 Ultrasonic Humidifier?
If you’re shopping because a small humidifier can’t keep up with your space, the Vornado UH200 Ultrasonic Humidifier makes a strong case. The combination of a 1.75-gallon tank, up to 4 gallons per day output, and an electronic humidistat is exactly what you want when the goal is whole-room comfort, not just a little mist near the unit.
Buy it if you want big-room capacity with simple controls and a remote, and you’re willing to stay on top of normal humidifier maintenance. If you’d rather avoid the water-quality quirks that come with ultrasonic humidifiers, it makes more sense to look at an evaporative model instead.
