Cold-Air Diffusion TechnologyWhat is cold-air diffusion for scenting?

Cold-air diffusion (nebulising technology) is the safest and cleanest way to diffuse 100% pure essential oils and fragrances, ensuring you get the absolute best out of every drop.

Instead of using heat, fans, or evaporation, VALAER scent machines use filtered ambient air to transform fragrances into an ultra-dry micro-mist. This ground-breaking technology uses no water, alcohol, or heat, allowing scents to be diffused in their purest form. The result: a cleaner, more consistent, and richer fragrance experience.

There are compelling reasons why cold-air diffusion is the gold standard for diffusing home fragrances and essential oils:

• Superior Coverage: Cold-air diffusers can transform spaces twice the size of those covered by typical candles, reed diffusers, plug-ins, or ultrasonic diffusers.

• Ultra-Pure: Our diffusers do not heat or dilute the fragrance oil. This perfectly preserves the integrity of every scent composition, without the risk of mould growth or lingering residue.

How does it work?

The oil is diffused via nebulisation—a process that breaks down essential oil into an extremely fine, dry mist that leaves no trace behind. The oil is then dispersed through the core of the diffuser using the ambient air in the room.

An internal air filter ensures that no dust particles or impurities from the outside environment interfere with the nebulising process. The result is a subtle, consistent, and perfectly scented indoor climate.

Furthermore, VALAER home diffusers are equipped with an internal intensity control, giving you full command over the entire process. Whether you prefer a subtle nuance or a bold presence: the choice is yours.

Our Cold-Air Diffusers All VALAER scent machines are designed with both aesthetics and high-performance in mind.

We utilise patented cold-air diffusion technology that protects the molecular integrity of our fragrance oils, ensuring you experience scents in their cleanest, most pure form. These revolutionary diffusers release fragrance as a micro-mist to ensure precise, long-lasting, and superior-quality coverage.

VALAER home diffusers are available in various minimalist designs that blend seamlessly into your interior. We also offer wall-mounted models that can easily be connected to your home’s HVAC or central climate control system. Many of our designs feature an intelligent control panel (and smart app control), allowing you to easily set scent intensity and specific operating schedules.
