Vornado
Vornado EV100
Vornado prints room sizes that the physics actually backs up. One gallon a day supports about 246 square feet by the standard winter calculation; Vornado prints 260 on the box. That is not a rounding coincidence - the same relationship holds across their whole line, which means somebody there is doing the load calculation instead of the marketing. The EV100 itself is a plain, small, well-built evaporative: one gallon, one wick, automatic humidity control, and a five-year guarantee that is unusually long for the money. It will not humidify an open-plan floor, and Vornado does not claim it will.
The room-size claim, reconciled
246 sq ft supported · box says 260 sq ft
The box says 260 sq ft; the winter load calculation puts the output at 246 sq ft — an overstatement of about 6%, which is modest for this category.
Holding 260 sq ft takes about 1.06 gal/day, which drains this 1-gallon tank in roughly 23 hr.
What a year costs
one wick per unit; Vornado's two-pack is $14.99 and asks for a change every one to two months in season, so about three a year. Electricity assumes the rated 14.3 W for 12 hours a day across a 150-day heating season at 16¢ per kilowatt-hour.
Specifications
A claim the maker makes
Vornado says the wick is treated with an antimicrobial to inhibit growth on the filter. We quote it rather than repeat it: this site has not tested it and neither has anyone independent.
Maintenance profile
- Top fill
- No — tank comes off and goes to the sink
- Replaceable media
- Wick, replaced through the season
Facts, not a score. Which of these matter depends entirely on whether the unit ends up somewhere you will actually clean it.
Features
- Published output of 1 gallon in 24 hours against a 260 sq ft claim
- Automatic humidity control
- SimpleTank with a removable cap for cleaning
- Evaporative - no white dust, tap water fine
- 5-year guarantee
- Vortex air distribution
Pros
- The room-size claim is genuinely supportable - the rarest thing in this category and the reason to buy Vornado over a spec-sheet rival
- Five-year guarantee at $70, against the one year most of this catalog offers
- Evaporative and self-limiting: it physically cannot over-humidify a room the way an unregulated ultrasonic can
- Owners consistently describe build quality a tier above the price
- Tank cap unscrews wide enough to clean inside properly
Cons
- One gallon a day genuinely is a small-room output - buyers comparing spec sheets against ultrasonics claiming 500 sq ft will think it underpowered, and the spec sheets are the ones lying
- Wicks at roughly $7.50 each every month or two
- Audible fan; it is how an evaporative works
- Bottom-fill tank has to go to the sink
What owners say
Summarised from owner discussions and long-form owner reviews. Nobody here has used this unit.
A plain, small, well-made evaporative, and the clearest example of the pattern that makes Vornado unusual: one gallon a day, 260 square feet on the box, and the load calculation says 246. The maker is doing the arithmetic rather than the marketing.
Owner reports on this particular model are few; the plastic body is thin for the money. The main risk with it is buyer disappointment for the wrong reason — set next to an ultrasonic claiming twice the room at the same price, it looks weak on paper, and the spec sheets are the ones being dishonest.
What owners like
- Vornado backs it with a five-year guarantee, the same as the rest of its evaporative line
- The room-size claim is supportable rather than aspirational, which almost nothing else at this price manages
- Evaporative and self-limiting, so it cannot soak a small room the way an unregulated ultrasonic can
- Five-year guarantee at $70
Common complaints
- The plastic body is thin, which owners note against the brand's otherwise good reputation
- One gallon a day genuinely is small-room output, so buyers comparing spec sheets against ultrasonics claiming 500 sq ft will think it underpowered
- A single wick every month or two is a modest but permanent cost
- Audible fan, and no display, timer or app
Questions owners ask
Is 260 square feet really all it does?
How long does the wick last?
Can it over-humidify a small room?

Vornado EV200
Two tanks instead of one, two wicks instead of one, and 2.4 gallons a day against a 580 sq ft claim - within about two percent of the load calculation, one of several Vornado figures that land that close. Refilling means carrying two 0.75-gallon tanks rather than one heavy one, which sounds like a downgrade and is not: most people find two light trips easier than one awkward one, and you can run it on a single tank overnight. Fifteen hours at full output is the honest tank life, and Vornado does not pretend otherwise.

Vornado EVDC300 Energy Smart
A DC motor is the only interesting thing here and it is interesting enough to justify the model. On its Energy Smart setting the EVDC300 draws as little as a single watt, against the fourteen to forty-five watts Vornado's AC evaporatives pull, and it runs the whole winter for the price of a few coffees. Output is 2.3 gallons a day - within one percent of what its 560 sq ft claim actually needs - from a one-gallon tank, which is the catch: ten hours between fills if you run it hard. It is the fill interval, not the capability, that decides whether this or the two-tank EV200 is the right one.

Vornado EVDC500 Energy Smart
The EVDC300's larger sibling: same DC motor and single-watt idle, two tanks instead of one, and enough output to matter in a real living room. At 3.5 gallons a day it is the most capable tabletop Vornado makes, and its 840 sq ft figure again sits within a few percent of the load calculation. Fourteen hours at full output, so still a daily job in a dry house - but two tanks make that a lighter job than one. The question it poses against the Evap40 console is whether you would rather carry water twice a day and keep the floor space, or once a day and give up a corner.
