Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
You are paying $29 for an app. The Dreo HM713S does warm and cool mist across 550-750 sq ft with a tighter ±5% humidistat for about $80. The LV600S earns its premium only if your other gear already runs on VeSync.

Traps — this verdict avoids
Why the Levoit LV600S is right for you
It avoids every trap below — and for two, under $150, it is the pick because it delivers:
The white dust tax
Ultrasonic humidifiers throw fine white mineral dust with hard water above 120 ppm TDS — it settles on furniture and electronics. You need distilled water, a demineralization cartridge, or an evaporative unit.
Phantom coverage
Coverage ratings are manufacturer numbers for a closed room at standard conditions. Open floor plans and ceilings over 9 ft cut real coverage 30-50% — size up, or shut the door.
The filter subscription
Evaporative wicks need replacing every 1-3 months at $10-20 each — $40-120 a year that never shows up on the price tag.
