Vornado EVDC500 Energy Smart vs Vornado Evap40
In short: The Vornado EVDC500 Energy Smart costs $30 less; the Vornado Evap40 genuinely holds a larger room (985 sq ft against 862 sq ft); they are different mechanisms entirely — evaporative against console evaporative; the Vornado EVDC500 Energy Smart costs about $9 less a year in wicks and watts.

Highlighted cells are the better number in that row, and only where a direction is unambiguous — more output and more supported room, less noise, cost and price. Honest room size and runtime are computed from each maker’s own published figures; here is the calculation.
Pros and cons
Vornado EVDC500 Energy Smart
- Most output of any portable Vornado while still drawing barely more power than a nightlight
- Honest coverage claim in a size bracket where every competitor inflates
- Dual tanks make the daily refill manageable
- Five-year guarantee, which counts for more on a motor that runs every hour of the season
- Two wicks, so the consumable bill matches the EV200's rather than the cheaper EVDC300's
- Fourteen hours at full output, so the dual tanks buy convenience rather than a second day
- At $120 it is competing with console evaporatives that hold three times the water
- No app and no scheduling, which at $120 is a real gap next to the ultrasonics
Vornado Evap40
- The one unit here whose headline runtime and headline coverage describe the same setting - Vornado says so explicitly
- A genuine day between fills at full output, which almost nothing portable manages
- Dual tanks split the 4-gallon refill into two carryable halves
- No white dust, tap water fine, and an evaporative's natural ceiling on over-humidifying
- Five-year guarantee and US manufacture at a price below the imported consoles
- Two wicks at a one-to-two-month interval is roughly $45 a year
- At full speed it is clearly audible - this is a console fan, not a bedroom appliance
- No app, no timer, no filter-change reminder
- Four gallons of water is heavy furniture once filled, and it does not move easily
