Our diffusers turn aroma oil into a fine, dry mist using cold-air nano technology. There's no water and no heat, so the scent stays true. Fill the oil bottle with Dr Scent oil (never add water), put it back and switch it on. Then use your phone to set the scent intensity, and the days and hours you want the diffuser to work.

Use Dr Scent aroma oils only. They're made for nano-mist diffusers. Thick, water-based or other brands' oils can clog the nozzle, and damage from them isn't covered by the warranty.

In the Dr Medium, a 500 ml bottle lasts about 2 months, and a 1000 ml bottle about 4 months. These figures are at intensity grade 7 for 8 hours a day. Lower grades or fewer hours make a bottle last longer.

See every intensity grade and work out your own use in our Intensity & Oil Use Guide

The Dr Medium holds 500 ml of oil at a time. We recommend the 1000 ml bottle: it refills the diffuser twice, lasts about 4 months and is our best value per ml. Choose 500 ml if you're trying a new scent.

Plug-in. Sit it on a table, mount it on the wall, or connect it to your ducted air-conditioning (HVAC). The tools for wall mounting and HVAC are included.

Wipe the oil bottle and the diffuser head with a soft, dry cloth each time you change oil. Don't rinse the diffuser or use cleaning products. If the mist gets weaker, contact us. A blocked nozzle is a quick fix and is covered under warranty.

Our oils are formulated to IFRA Standards, the international safe-use limits for fragrance ingredients, and our diffusers use no water or heat. Because everyone reacts to scent differently, start on a low intensity and keep an eye on children and pets the first time you use a new scent. Keep the diffuser out of reach of children and pets.

Somewhere central and higher up, so the mist spreads before it settles: a shelf, a cabinet top or the wall. Keep the nozzle at least 30 cm from walls, furniture, artwork and electronics, and point it away from air-conditioning returns.

Ultrasonic diffusers mix a few drops of oil with water and make a wet mist that covers a small room and adds humidity to the space. Ours diffuse pure oil as a dry mist, so the scent is stronger, covers more space, adds no moisture and there's no water tank to clean.

Yes. The Dr Medium can be connected to your ducted air-conditioning (HVAC) system, and it comes with the tools to do it. Contact us for help with setup.
