Best waterless diffuser in Australia: what to check before you buy

The best waterless diffuser for you runs long enough for your room, has a timer or settings you will actually use, is quiet enough for where you put it, fits the oil bottles you buy, and is easy to keep clean. For damp rooms, the main reason to go waterless is that it adds no water to the air. Check these seven points before you pay.

For a diffuser without a water tank, see our Waterless Diffuser for A$59.99; it puts fine oil droplets into the air and adds no water to the room.

1. Run time and settings

How long does it run on one charge or one cycle? Can you set intensity? You want enough control to run it 30 to 60 minutes in one room without babysitting it.

2. Oil use

Waterless units use oil faster than ultrasonic ones because nothing dilutes it. Ask the seller how long a bottle lasts in daily use. More: nebulising diffuser.

3. Noise

Air pumps make some sound. If it is for a bedroom, look for a seller who says it is quiet enough for overnight use.

4. Bottle fit

Some units screw straight onto a standard essential-oil bottle. Some need their own reservoir. Check the thread size and bottle sizes it takes.

5. Cleaning

No water tank means no slime. You still need to keep the nozzle clear. Check the manual for how.

6. Power

Plug-in, USB, or rechargeable battery? A battery unit can go on a bathroom shelf with no cord near the shower.

7. Price and what is in the box

Is a wall plug included? Is oil included? What is the return policy?

Which rooms need a waterless unit most

Bathrooms, laundries, bedrooms on an external wall, and any room that fogs its windows. In those rooms an ultrasonic unit adds water you do not need. Full comparison: waterless vs ultrasonic diffuser.

For damp rooms we built the Protection Kit: our Waterless Diffuser with one, two or three bottles of First Light. First Light is our six-oil blend of clove, litsea cubeba, tea tree, eucalyptus, peppermint and cedarwood. Lab tested: 99.2% on direct contact. See the lab test. See the lab test.

Use the diffuser in a ventilated room and keep the unit and the bottle out of reach. Directions: how to use and product use and safety.

FAQ

What should I look for in a waterless diffuser?

Run time and settings, oil use, noise, bottle fit, cleaning, power source, and price including what is in the box.

Are waterless diffusers better than ultrasonic diffusers?

For damp rooms, yes, because they add no water. Ultrasonic units use less oil because they dilute it in water.

Do waterless diffusers use a lot of oil?

More than ultrasonic ones. With our unit and First Light, one 15 ml bottle lasts about six weeks of daily use in one room.

Can I use a waterless diffuser in a bathroom?

Yes, on a shelf away from the shower spray. A battery unit avoids a cord near water. Follow the product directions.
