Levoit LV600S vs Dreo HM713S
In short: The Dreo HM713S costs $20 less; the Levoit LV600S genuinely holds a larger room (860 sq ft against 781 sq ft); the Dreo HM713S costs about $20 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
Levoit LV600S
- Levoit publishes the mL/hr output, which almost nobody in this category does - it makes the unit's real capability checkable
- 3.49 gallons a day on warm is genuine large-room capability, not a marketing number
- Owners report it visibly moving a hygrometer in a room where smaller ultrasonics did nothing
- Warm mode doubles as a mild deterrent to tank growth
- Widely available and long enough in market that parts and tanks are easy to source
- About eleven hours of tank at full warm output - refilling daily is the reality at that setting
- 280W on warm mist, a small fraction of that on cool, and the running-cost figure here assumes you use it
- No demineralisation cartridge included; white dust is the predictable result on hard water
- The gap between the 50-hour claim and the 11-hour reality at full output is the most common source of disappointment with this model
Dreo HM713S
- One of the few ultrasonics whose published coverage claim is conservative against its own published output
- Warm mist and 3.17 gal/day capability in a unit that still fits on a side table
- Dual aroma pad tray, so oils stay out of the water
- Twelve hours of tank at full output, against the 60-hour low-setting claim
- The warm setting is what makes it expensive to run; cool mist costs roughly a tenth as much
- No demineralisation cartridge in the box; on hard water it is a $25.99 three-pack on top, changed every two months
