How does an ultrasonic diffuser work?

Ultrasonic diffusers use a ceramic plate vibrating at ultrasonic frequency to break water and fragrance oil into a fine, cool mist. This mist carries the scent into the air without heat, preserving the oil's scent profile. Simply fill the tank with water, add 5-7 drops of fragrance oil, and turn it on.

What is a waterless diffuser and how is it different?

A waterless diffuser (nebulizer) atomises pure fragrance oil into a dry micro-vapour without water. The scent is stronger and more true-to-note since there is no dilution. Waterless diffusers cover larger areas (800+ sq ft), require no cleaning, and have zero mould risk. They use more oil per session but deliver a premium scent experience.

How do I clean my ultrasonic diffuser?

Wipe the water tank dry after every few uses. For a deep clean, fill the tank with clean water and a teaspoon of white vinegar, run for 5 minutes, then drain and wipe dry. This prevents mineral buildup and old oil residue. Use RO or distilled water to avoid mineral deposits, especially in hard-water areas like Delhi.

Can I use any fragrance oil in Azhara diffusers?

Azhara diffusers are designed for use with Azhara fragrance oils and standard water-soluble fragrance oils. Avoid thick carrier oils, perfumes, or alcohol-based fragrances as they can damage the ultrasonic plate. Essential oils work well too.

Is it safe to run the diffuser overnight?

Yes. All Azhara diffusers feature auto-shutoff that turns the device off when the water level is low. For overnight use, we recommend intermittent mist mode - it cycles the mist on and off, which is gentler on the senses and makes your oil last longer.

What size room can this diffuser cover?

Ultrasonic diffusers like the Aurea cover approximately 200-300 sq ft - ideal for a standard Indian bedroom or home office. Waterless diffusers like the Ether and Stelo cover 500-800+ sq ft, suitable for living-dining areas in 2-3 BHK apartments.

Does Azhara offer free shipping on diffusers?

Yes, all diffuser orders qualify for free shipping across India as they exceed the ₹2,000 threshold. Delivery takes 2-7 working days via insured, trackable service.
