Cost-Saving Tips

  • $ Ultrasonic models use only 25W vs 250-400W for warm mist, saving $20-60/year on electricity.
  • $ Filterless ultrasonic humidifiers eliminate wick replacement costs ($30-60/year savings).
  • $ Using distilled water extends filter life and reduces mineral buildup maintenance.
  • $ Auto humidity control runs the unit only when needed, reducing both energy and filter wear.
