How to Choose & Care for Your Diffuser

Start with the room.

For a bedroom, desk, or reading corner, a compact ultrasonic diffuser is usually a comfortable fit. For a living room or longer sessions, choose a larger water tank. If you want stronger fragrance without refilling water, consider a cold-air or waterless diffuser.


Choose the right oil.

Ultrasonic diffusers use water with essential oils or water-compatible diffuser oils. Waterless diffusers require oils made for cold-air diffusion. Do not add body oil, carrier oil, reed-diffuser refill, or thick resin to an ultrasonic water tank.


Care for an ultrasonic diffuser.

  • Use clean, room-temperature water and stay below the maximum fill line.
  • Start with the amount of oil recommended on the bottle.
  • Empty unused water after each session.
  • Wipe the tank with a soft, non-abrasive cloth.
  • Keep water away from the air outlet and electrical base.

Care for a waterless diffuser.

  • Use only oil formulated for the device and bottle connection.
  • Begin on a low setting and increase gradually.
  • Clean the fragrance pathway before changing to a very different fragrance or when output declines.
  • Keep the unit upright on a stable surface.

Place it safely.

Set your diffuser on a stable, moisture-resistant surface with open space around the outlet. Keep it away from direct sunlight, electronics, polished surfaces, fabric, children, and pets. Stop using a diffuser that leaks, overheats, makes an unusual noise, or shows visible damage. Always follow the guide included with your product.
