Ultrasonic Diffusers

Soft mist, soft light, soft scent. MERA ultrasonic diffusers turn water and a few drops of oil into a fine, fragrant mist — often with a gentle glow — for a calming, room-filling aroma that's easy to control.

How to choose

Larger tanks run longer and cover bigger rooms; look for timer and light settings to suit your routine. Quiet operation makes these a favorite for bedrooms, nurseries, and offices.

Best for

  • Calming, room-filling scent
  • Bedrooms, living rooms, and offices
  • Flame-free homes with kids or pets
