What type of diffuser should I use?

Divinely aromatic, essential oils are highly concentrated and potent forms of nature that are at the heart of every HYSSES product. More than just aromatic scents, essential oils are all-natural plant extracts capable of complex effects on human physiology and physical well-being. You have made the right decision if you are considering essential oils to cure various ailments or to maintain your health in a holistic way. This is where the nebuliser or the mist diffuser comes into play; you can come home from work, add a few drops of your favourite essential oil, and relax as your stress melts away. Aroma nebuliser vs. Ultrasonic mist diffuser, which one is right for you?

What type of diffuser should I use?

Do you face respiratory issues or breathing problems while sleeping? Consider having a nebuliser in your room during your essential oil aromatherapy sessions or at night. Often considered the best type of machine for the therapeutic use of essential oil diffusion, the Nebuliser uses cold air nebulising technology to break down the essential oils into microdroplets which are then dispersed into the air as a mist. These microdroplets are the optimum size for inhalation through the lungs, entering the bloodstream, and allowing deep therapeutic action. In addition, the microdroplets can stay suspended in the air for longer periods, maximising the scenting effects and therapeutic benefits of essential oil. The latest series of HYSSES Aroma Nebuliser operates either with or without an adaptor. With an in-built battery that will operate for up to 6 hours, you can also easily relocate it anywhere. The HYSSES Ultrasonic Mist Diffuser uses ultrasonic frequencies to create vibrations on the water surface. The vibrations produce negative ions and vaporises essential oil into microdroplets. The microdroplets can stay suspended in the air for longer periods, maximising the scenting effects and therapeutic benefits of essential oil. Indulge in HYSSES avant-garde Ultrasonic Water Mist that integrates modern technology with heritage craftsmanship to give that quality statement to your lifestyle. Powered with an in-built battery, the machine can now be easily relocated and moved anywhere conveniently. The machines come with Safety Mark and local technical after-sales support services.

Differences between Nebuliser & Water Mist






·         Uses the full potential of essential oil. Oil is atomised into tiny particles and dispersed into the air as waterless mist. The scent strength is stronger than Water Mist

·         For mould or humidity issues, nebuliser is a better option for water-less operation


·         Water mist atomises both water and essential oil to humidify the air instantly. Low air humidity results in dehydrated & aged skin.

·         Higher humidity combat dry air and helps to avoid cold and flu.

·         It also helps to clear nasal passages irritated by allergies.

·         Reduces dust in the air. The water mist diffuser acts as an ioniser, it releases negative ions which attach to positive ions. This causes the dust in the air to fall to the ground.

·         Easily and cheaply available in mass-produced plastic versions. However, the essential oils may degrade, melt the plastics, and form toxic compounds.

·         HYSSES Ultrasonic Water Mist uses essential oil compatible materials i.e. glass, ceramics, or wood to ensure integrity in the benefits of the essential oils (without toxicity) is maintained.




·         Avoid thicker viscosity oils or paired with thinner oil

·         Avoid diluted oils, as well as water-based essential oils

·         The glass filament is very delicate and can be clogged if it is not well cleaned. It requires frequent cleaning with proper maintenance



·         Water mist releases a lot of moisture into the air (similar to a humidifier) which may not be ideal for homes that don’t require humidification

·         The scent emitted is slightly weaker as compared to Nebuliser

·         Available in cheaply mass-produced plastics machines which may be mistaken as Water Mist
